Description

Technical Field

[0001] This invention belongs to the field of temperature tracing technology, and particularly relates to an intelligent temperature-controlled heat tracing tape and its manufacturing method. Background Technology

[0002] Intelligent temperature tracing tape (self-regulating electric temperature tracing tape) is a pipe insulation and antifreeze device that achieves automatic temperature regulation through conductive polymer materials. Its core features include self-temperature control, energy efficiency, and adaptability to complex environments. By using a PTC conductive composite material layer, the resistance automatically increases when the temperature rises to reduce power consumption, achieving precise temperature control without the need for an external temperature controller.

[0003] In the manufacturing process of temperature tracing tape, high molecular polymers (such as polyethylene) and carbon black (conductive filler) need to be mixed. The proportion of carbon black needs to be precisely controlled within a certain range to achieve PTC characteristics. Therefore, how to accurately control the proportion of carbon black during the manufacturing process is crucial to ensuring the temperature control performance of the temperature tracing tape.

[0004] To address the aforementioned technical problems, this application provides an intelligent temperature-controlled heat tracing cable and its manufacturing method. Summary of the Invention

[0005] To achieve the objectives of this invention, the following technical solution is adopted: Specifically, this application provides a method for manufacturing an intelligent temperature-controlled heating tape, which includes: S1 determines the temperature measurement data of the temperature tracing belt based on the test data of the temperature tracing belt, and determines the number of test samples of the temperature tracing belt at each length based on the temperature measurement data when there is a deviation in the uniformity of the distribution of the conductive composite material of the temperature tracing belt. S2 determines the manufacturing method of the heat tracing band based on the number of test samples and the test results of the matching carbon black ratio of the conductive composite material at each length when the test results meet the requirements. This determination is based on the similarity of the matching carbon black ratio of the conductive composite material at each length and the resistivity data.

[0006] The beneficial effects of this invention are as follows: Based on the uniformity of the conductive composite material distribution of the temperature tracing belt, the number of test samples for each length of the temperature tracing belt is determined. This allows for the determination of the uniformity deviation of the conductive composite material distribution from the perspective of the uniformity of temperature measurement data. Furthermore, based on the uniformity deviation of the distribution, the number of test samples for each length is determined, thus ensuring that the test results can more accurately reflect the true state.

[0007] Based on the similarity of the matching carbon black ratio of conductive composite materials at various lengths and the resistivity data, the manufacturing method of the heat tracing tape is determined. This enables the screening of matching carbon black ratios that meet the requirements for temperature detection data at most lengths, and the screening of matching carbon black ratios with lower resistivity based on the resistivity data of the matching carbon black ratios. Furthermore, it combines the screening of lengths where the temperature test data does not meet the requirements for matching carbon black ratios that meet the requirements for temperature detection data at most lengths, thereby avoiding the technical problem of poor operational reliability caused by manufacturing the heat tracing tape at the aforementioned lengths.

[0008] Furthermore, the temperature measurement data of the temperature tracing belt includes temperature measurement data at different temperature measurement points during the testing process.

[0009] Furthermore, it was determined that there was a deviation in the uniformity of the distribution of the conductive composite material of the temperature tracing zone, specifically including: Based on the temperature measurement data, the temperature measurement data of the temperature tracing belt at different temperature measurement points during the test process are determined; Based on temperature measurement data at different temperature measurement points, the distribution data of abnormal temperature measurement points of the temperature tracing belt are determined; Using the distribution data, it is determined whether there is any deviation in the uniformity of the distribution of the conductive composite material in the temperature tracing zone.

[0010] Furthermore, when determining whether the test results for the matched carbon black ratio range of the conductive composite material at various lengths meet the requirements, specifically including: Determine the matching carbon black percentage data for the conductive composite material at the stated length; Based on the matching carbon black ratio data and the number of test samples, determine whether the test results of the matching carbon black ratio range of the conductive composite material at each length meet the requirements.

[0011] Furthermore, the method for determining the manufacturing method of the heat tracing belt is as follows: Based on the similarity of the matching carbon black ratio of conductive composite materials at various lengths, the length to which the matching carbon black ratio belongs is determined and used as the matching length. Based on the resistivity data of the matched carbon black percentage, determine the unit resistance at different matching lengths within the matched carbon black percentage. Based on the unit resistance at different matching lengths and the matching length data of the proportion of matching carbon black, the manufacturing method of the heat tracing band is determined.

[0012] Secondly, the present invention provides an intelligent temperature-controlled heating cable, employing the aforementioned manufacturing method of an intelligent temperature-controlled heating cable, comprising: Conductive composite materials, metal wires, polyolefin insulation layers, metal shielding layers, outer sheaths, junction boxes and connectors.

[0017] To enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. Based on the embodiments of this specification, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this specification.

[0018] In this application, when the carbon black content in the conductive composite material of the heat tracing tape is uneven, a test scheme is determined for different lengths based on the uniformity of the distribution. The test results under different carbon black contents are used to screen lengths with poor temperature control reliability, thereby determining the manufacturing method of the heat tracing tape, thus ensuring the reliability of temperature control and the safety of operation of the heat tracing tape.

[0019] Example 1 like Figure 1As shown, this application provides a method for manufacturing an intelligent temperature-controlled heating tape, specifically including: S1 determines the temperature measurement data of the temperature tracing belt based on the test data of the temperature tracing belt, and determines the number of test samples of the temperature tracing belt at each length based on the temperature measurement data when there is a deviation in the uniformity of the distribution of the conductive composite material of the temperature tracing belt. Furthermore, the temperature measurement data of the temperature tracing belt includes temperature measurement data at different temperature measurement points during the testing process.

[0020] Specifically, such as Figure 2 As shown, there are deviations in the uniformity of the distribution of the conductive composite material in the temperature tracing zone, specifically including: Based on the temperature measurement data, the temperature measurement data of the temperature tracing belt at different temperature measurement points during the test process are determined; Based on temperature measurement data at different temperature measurement points, the distribution data of abnormal temperature measurement points of the temperature tracing belt are determined; By using the distribution data of abnormal temperature measurement points in the temperature tracing belt, the number of abnormal temperature measurement points in the temperature tracing belt is determined. Based on the number of abnormal temperature measurement points in different temperature tracing belts, it is determined whether there is a deviation in the uniformity of the distribution of the conductive composite material of the temperature tracing belt.

[0021] It should be noted that when the average length of the temperature tracing tape does not meet the requirements during the test process, if the number of abnormal temperature measurement points exceeds the preset threshold for the number of temperature measurement points, it is determined that there is a deviation in the uniformity of the distribution of the conductive composite material of the temperature tracing tape.

[0022] In a possible specific embodiment, when a temperature measurement process with more than 4 abnormal temperature measurement points and an average length of less than 20 meters for the temperature tracing tape is used, it is determined that there is a deviation in the uniformity of the distribution of the conductive composite material of the temperature tracing tape.

[0023] It is understood that the uniformity of distribution includes test data from abnormal temperature measurement points in the temperature tracing zone at different lengths.

[0024] Specifically, such as Figure 3 As shown, the method for determining the number of test samples of the specified length using the temperature tracing band is as follows: Based on the uniform distribution, the distribution data of abnormal temperature measurement points of the temperature tracing belt at different lengths during the test process are determined; Based on the distribution data, the test process corresponding to the temperature tracing strip with a number of abnormal temperature measurement points greater than the preset threshold for the number of temperature measurement points under different lengths is determined and regarded as an abnormal test process. By using abnormal test process data corresponding to different lengths, the proportion of abnormal test processes at different lengths is determined, and the number of test samples of the temperature tracing band at that length is determined based on the proportion of abnormal test processes at different lengths.

[0025] It should be noted that when the average percentage of abnormal test processes under different lengths does not meet the requirements, the baseline quantity is used to determine the number of test samples under different lengths.

[0026] In one possible embodiment, if the average percentage of the number of abnormal test processes under different lengths is greater than 0.07, then it is determined that the average percentage of the number of abnormal test processes under different lengths does not meet the requirements.

[0027] It should be noted that the lengths include 10m, 20m, 30m, 40m, 50m, etc., with intervals of 10 meters up to 100m.

[0028] It should be noted that the number of test samples refers to the number of samples whose operating temperature was observed during the test process under different carbon black ratios.

[0029] Furthermore, when the average percentage of abnormal test processes under different lengths meets the requirements, it is also necessary to determine when the length where the percentage of abnormal test processes does not meet the requirements is less than the preset length threshold. In this case, the benchmark quantity is used to determine the number of test samples under different lengths.

[0030] Additionally, it can be understood that when the length where the proportion of abnormal test processes does not meet the requirements is less than a preset length threshold, the number of test samples is determined by a baseline quantity under the length where the proportion of abnormal test processes does not meet the requirements. However, under the length where the proportion of abnormal test processes meets the requirements, the number of test samples under the length is determined based on the proportion of abnormal temperature measurement processes under the specified length.

[0031] It should be noted that the matched carbon black ratio refers to the carbon black ratio of the conductive composite material at which there are no abnormal temperature measurement points.

[0032] S2 determines the manufacturing method of the heat tracing band based on the number of test samples and the test results of the matching carbon black ratio of the conductive composite material at each length when the test results meet the requirements. This determination is based on the similarity of the matching carbon black ratio of the conductive composite material at each length and the resistivity data.

[0033] Specifically, such as Figure 4 As shown, the test results confirm that the matched carbon black ratio range of the conductive composite material at various lengths meets the requirements, specifically including: Determine the matching carbon black percentage data for the conductive composite material at the stated length; Based on the matching carbon black ratio data and the number of test samples, determine whether the test results of the matching carbon black ratio range of the conductive composite material at each length meet the requirements.

[0034] It is understood that, based on the aforementioned matching carbon black ratio data and the number of test samples, the test results for the matching carbon black ratio range of the conductive composite material at various lengths are used to determine whether they meet the requirements. Specifically, this includes: The matching ratio at each length is determined by the ratio of the proportion of the matched carbon black at the specified length to the number of test samples. Based on the matching ratio at different lengths, the test results of the matching carbon black ratio range of the conductive composite material at each length are determined to meet the requirements.

[0035] It should be noted that if the matching ratio is greater than the preset matching ratio threshold at different test lengths, then the test results of the matching carbon black ratio range of the conductive composite material at each length meet the requirements.

[0036] In one possible embodiment, if the matching ratio is greater than 0.05 at different test lengths, then the test results for the matching carbon black ratio range of the conductive composite material at each length are determined to meet the requirements.

[0037] Specifically, such as Figure 5 As shown, the method for determining the manufacturing method of the temperature tracing belt is as follows: Based on the similarity of the proportion of matched carbon black in conductive composite materials at various lengths, the length to which the proportion of matched carbon black belongs is determined and is taken as the matching length. Based on the number of the matching lengths, the proportion of matched carbon black with the largest number of matching lengths is determined and is taken as the available proportion. Based on the resistivity data of the available percentage, determine the unit resistance at different matching lengths within the available percentage; The manufacturing method of the heat tracing band is determined based on the unit resistance at different lengths and the matching length data of the available proportion.

[0038] It should be noted that if the unit resistance of the available percentage at different lengths does not meet the requirements or the number of matching lengths corresponding to the available percentage does not meet the requirements, then it is determined that the test process will continue at different lengths until the matching carbon black percentage that meets the above conditions is obtained, that is, the unit resistance at different lengths meets the requirements and the number of matching lengths corresponding to the available percentage meets the requirements.

[0039] In one possible specific embodiment, the process continues until the unit resistance at different lengths is less than 30 ohms and the number of matching lengths corresponding to the available percentage is not less than 4.

[0040] Additionally, it should be noted that when the unit resistance of the available percentage meets the requirements at different lengths or the number of matching lengths corresponding to the available percentage meets the requirements, if the available percentage belongs to the matching carbon black percentage at all lengths, then the available percentage is used as a manufacturing parameter, and the manufacturing process of the heat tracing tape is based on the manufacturing parameter.

[0041] It should also be noted that if the available percentage is not uniformly within the matching carbon black percentage across all lengths, and the number of matching carbon black percentages for lengths that are not within the matching carbon black percentage is insufficient, then the available percentage will be used as a manufacturing parameter, and the heat tracing tape will be manufactured based on this parameter. Furthermore, the lengths that are not within the matching carbon black percentage will no longer be manufactured.

[0042] Furthermore, if a length that does not belong to the matching carbon black percentage under the available percentage, and the corresponding number of matching carbon black percentages is uneven and does not meet the requirements, then it is determined that the testing process will continue under different lengths until a matching carbon black percentage that meets all the above conditions is obtained, that is, until a length that does not belong to the matching carbon black percentage under the available percentage, and the corresponding number of matching carbon black percentages does not meet the requirements, or until an available percentage that belongs to the matching carbon black percentage under all lengths is obtained.

[0043] Example 2 Secondly, the present invention provides an intelligent temperature-controlled heating cable, employing the aforementioned manufacturing method of an intelligent temperature-controlled heating cable, comprising: Conductive composite materials, metal wires, polyolefin insulation layers, metal shielding layers, outer sheaths, junction boxes and connectors.

[0044] Furthermore, it was determined that there was a deviation in the uniformity of the distribution of the conductive composite material of the temperature tracing zone, specifically including: Based on the temperature measurement data, the temperature measurement data of the temperature tracing belt at different temperature measurement points during the test process are determined; Based on temperature measurement data at different temperature measurement points, the distribution data of abnormal temperature measurement points of the temperature tracing belt are determined; Using the distribution data, it is determined whether there is any deviation in the uniformity of the distribution of the conductive composite material in the temperature tracing zone.

[0045] It is understood that the abnormal temperature measurement point is a temperature measurement point where the deviation of the average value of the temperature measurement data from different temperature measurement points of the temperature tracing belt does not meet the requirements.

[0046] In one possible embodiment, if the deviation of the average temperature data of the temperature measurement point from the average temperature measurement data of different temperature measurement points of the temperature tracing band is greater than 5 degrees Celsius, then the temperature measurement point is determined to be an abnormal temperature measurement point.

[0047] It is understandable that when there are abnormal temperature measurement points in the temperature tracing bands in different test processes, it is determined that there is a deviation in the uniformity of the distribution of the conductive composite material of the temperature tracing bands.

[0048] It should be noted that when the distribution of the conductive composite material of the heat tracing tape is uniform and there is no deviation, the heat tracing tape is still manufactured according to the original manufacturing method.

[0049] It should be noted that during the test, the temperature tracing belt was operated continuously for 72 hours under rated voltage, and temperature measurement was performed at different temperature measurement points using temperature measuring equipment during the test.

[0050] Example 3 Furthermore, the method for determining the number of test samples of the length of the temperature tracing band is as follows: Based on the uniform distribution, the distribution data of abnormal temperature measurement points of the temperature tracing belt at different lengths during the test process are determined; Based on the distribution data, the test process corresponding to the temperature tracing strip with a number of abnormal temperature measurement points greater than the preset threshold for the number of temperature measurement points under different lengths is determined and regarded as an abnormal test process. By using abnormal test process data corresponding to different lengths, the number of test samples of the temperature tracing band at that length is determined.

[0051] It is understood that the abnormal test process is the test process corresponding to when the number of abnormal temperature measurement points of the temperature tracing band under the specified length is greater than the preset threshold for the number of temperature measurement points.

[0052] It should be noted that when the proportion of abnormal test processes does not meet the required length, the number of abnormal temperature measurement points at different lengths is relatively small. Based on this, the number of test samples at the specified length is determined according to the proportion of abnormal temperature measurement processes at the specified length.

[0053] In one possible embodiment, if the proportion of abnormal test processes in the test process is less than 0.05 at different lengths, it is determined that there is no length where the proportion of abnormal test processes does not meet the requirements. In this case, the number of test samples at the length is determined by multiplying the proportion of abnormal test processes in the test process by a preset ratio coefficient, wherein the preset ratio coefficient is 1000.

[0054] Furthermore, when the proportion of abnormal test processes does not meet the required length, the maximum value of the proportion of abnormal test processes under different lengths is determined. If the maximum value of the proportion of abnormal test processes under different lengths does not meet the requirements, or if the length where the proportion of abnormal test processes does not meet the requirements is less than the preset length threshold, then the benchmark quantity is used to determine the number of test samples under different lengths.

[0055] In one possible specific embodiment, if the maximum percentage of abnormal test processes at different lengths is greater than 0.1, or if the length at which the percentage of abnormal test processes does not meet the requirement is no more than 20 meters, then the number of test samples will be set to 100 at different lengths.

[0056] Additionally, it is understandable that if the maximum value of the proportion of abnormal test processes under different lengths meets the requirements, or if there are lengths where the proportion of abnormal test processes does not meet the requirements but is not less than the preset length threshold, then the proportion of abnormal test processes under lengths where the proportion of abnormal test processes does not meet the requirements is determined as the weight value. When the sum of the weight values ​​of abnormal test processes where the proportion of abnormal test processes under different lengths does not meet the requirements is greater than the preset weight threshold, then the benchmark quantity is used to determine the number of test samples under different lengths.

[0057] In one possible specific embodiment, if the proportion of abnormal test processes under different lengths does not meet the requirement that the sum of the weight values ​​of abnormal test processes is greater than 0.2, then it is determined that the baseline quantity is used to determine the number of test samples under different lengths.

[0058] Furthermore, it should be noted that when the sum of the weight values ​​of abnormal test processes that do not meet the requirements under different lengths is greater than the preset weight threshold, the number of test samples is determined by a benchmark quantity under the length where the number of abnormal test processes does not meet the requirements, while under the length where the number of abnormal test processes meets the requirements, the number of test samples under the length is determined according to the number of abnormal temperature measurement processes under the length.

[0059] Example 4 Furthermore, the method for determining the manufacturing method of the heat tracing belt is as follows: Based on the similarity of the matching carbon black ratio of conductive composite materials at various lengths, the length to which the matching carbon black ratio belongs is determined and used as the matching length. Based on the resistivity data of the matched carbon black percentage, determine the unit resistance at different matching lengths within the matched carbon black percentage. Based on the unit resistance at different matching lengths and the matching length data of the proportion of matching carbon black, the manufacturing method of the heat tracing band is determined.

[0060] It should be noted that the unit resistance refers to the resistance per meter of the temperature-trapped zone.

[0061] It is understandable that when there is a matching carbon black percentage that is consistent with the required unit resistance under different lengths, the matching carbon black percentage that is consistent with the required unit resistance under different lengths is used as a manufacturing parameter, and the manufacturing process of the heat tracing tape is carried out based on the manufacturing parameter.

[0062] In one possible embodiment, if the unit resistance is less than 30 ohms, then the unit resistance is determined to meet the requirement.

[0063] Additionally, it should be noted that when there is no matching carbon black percentage that meets the requirements for unit resistance across different lengths, the matching carbon black percentage that meets the unit resistance requirement is obtained and used as a candidate percentage. When the number of matching lengths meets the requirements for the candidate percentage, it is used as the target matching percentage. If the number of target matching percentages does not meet the requirements, the testing process continues at different lengths until the number of target matching percentages meets the requirements or until there is a matching carbon black percentage that meets the requirements for unit resistance across different lengths.

[0064] In one possible specific embodiment, the proportion of candidate lengths with a number of matching lengths of not less than 3 is used as the target matching proportion, wherein when the number of target matching proportions is more than 10, it is determined that the number of target matching proportions meets the requirements.

[0065] Furthermore, when the number of the target matching percentages meets the requirements, the number of target matching percentages corresponding to different matching lengths is obtained according to the matching lengths corresponding to the target matching percentages. When the number of target matching percentages is less than the number of matching lengths that meet the requirements, the test process continues at different lengths until the number of target matching percentages meets the requirements or there is a number of matching carbon black percentages that are all matching carbon black percentages at different lengths and whose unit resistance meets the requirements.

[0066] In one possible specific embodiment, when the number of target matching percentages is less than 5 and the number of matching lengths is not less than 2, it is determined that the number of target matching percentages does not meet the requirement and the number of matching lengths does not meet the requirement.

[0067] Additionally, it should be noted that when the number of matching lengths with a target matching ratio that is less than the preset target matching ratio threshold meets the requirements, the matching lengths under different target matching ratios are obtained. If the number of target matching ratios corresponding to the matching lengths under the target matching ratios all meet the requirements, it indicates that the reliability of temperature control of the matching lengths under the target matching ratios all meet the requirements. Therefore, the target matching ratio is used as the available matching ratio. In one possible embodiment, if the number of target matching percentages corresponding to the matching length under the target matching percentage is not less than 5, then it is determined that the number of target matching percentages corresponding to the matching length meets the requirements.

[0068] It should be noted that when the number of lengths that are not part of the available matching percentage and the corresponding target matching percentages do not meet the requirements, the available matching percentage is used as a manufacturing parameter, and the heat tracing tape is manufactured based on the manufacturing parameter. The lengths that are not part of the available matching percentage are no longer manufactured.

[0069] It should also be noted that when the number of lengths that are not part of the available matching percentage and the corresponding target matching percentages are uneven and do not meet the requirements, it indicates that the lengths that are not part of the available matching percentage may be missing due to insufficient test data. In this case, testing should continue under different target matching percentages until an available matching percentage is obtained in which the number of lengths that are not part of the available matching percentage and the corresponding target matching percentages do not meet the requirements.

[0070] It is understandable that as the proportion of carbon black increases, the unit resistance decreases. As a result, in the case of non-uniformity, the PTC effect in the conductive composite material weakens, leading to a higher probability of overheating. At the same time, the decrease in the proportion of carbon black may result in a larger voltage drop at the end when the length is too long, which may also lead to a higher probability of abnormal temperature measurement points. Therefore, there may be some differences in the matching carbon black proportion under different lengths.
