Description

Technical Field

[0001] This invention relates to the field of combustion testing technology, and in particular to a method for automatically calculating and determining the critical radiative flux of flooring materials. Background Technology

[0002] According to current standards and specifications, when testing the combustion performance of flooring materials using the radiant heat source method as per GB / T 11785-2005 "Determination of Combustion Performance of Flooring Materials - Radiant Heat Source Method", the test process requires first using a simulated sample. Once the radiant heat source plate reaches a stable combustion state, the radiant flux at different locations on the simulated sample is measured and recorded using a radiant flux measurement probe, forming a radiant flux curve. Then, the simulated sample is replaced with the actual flooring material sample used for the test, and a combustion test is conducted. During the test, the distance the flame propagates across the sample surface at different times is recorded. After the test, based on the flame propagation distance and the radiant flux curve, the critical radiant flux for different propagation distances is calculated.

[0003] For existing critical radiative flux tests on paving materials, some methods involve plotting radiative flux curves and using manipulative plots to estimate the critical radiative flux at different times. This method has several drawbacks: (1) The calculation accuracy is low, and the manual drawing method cannot meet the requirements of standard GB / T 11785-2005 for "calculating the critical radiative flux, accurate to 0.2kW / m²". 2 Technical requirements.

[0004] (2) The manual drawing method cannot trace the calculation process of critical radiation flux.

[0005] (3) The manual drawing method requires drawing and calculating the critical radiation flux for each flame propagation distance separately, which is inefficient.

[0006] (4) The current method does not have the function of automatically determining the critical radiation flux.

[0007] Furthermore, the current software for the critical radiation flux testing device for paving materials does not include a method for automatically calculating the critical radiation flux, nor does it mention a method for automatically determining the critical radiation flux. Summary of the Invention

[0008] In view of the above problems, the present invention is proposed to provide an automatic calculation and determination method for the critical radiation flux of paving materials that overcomes or at least partially solves the above problems.

[0009] This invention discloses an automatic calculation and determination method for the critical radiative flux of paving materials, the method comprising: S1. The critical radiation flux test equipment for paving materials has finished preheating and the test begins. S2.

After the test data stabilizes, the computer software records the thermal radiation flux value at this moment and assigns it to F210, with the unit being kW / m². 2Similarly, the thermal radiation flux values ​​at different locations of 310 mm, 410 mm, 510 mm, 610 mm, 710 mm, 810 mm, and 910 mm were obtained, and these values ​​were assigned to F310, F410, F510, F610, F710, F810, and F910, respectively, with units of kW / m². 2 Take out the simulated sample and complete the establishment of the radiation flux curve.

[0022] The present invention provides a scheme for automatically calculating and determining the critical radiative flux of paving materials, and the specific steps are as follows: Step (1): The critical radiation flux test equipment for paving materials is preheated and the test begins; Step (2): Establishing the radiation flux curve. The radiation flux curve can be established by selecting a historical radiation flux curve or by creating a new radiation flux curve. If a historical radiation flux curve is selected, proceed to step (3); if a new radiation flux curve is created, proceed to step (4).

[0023] Step (3): Select historical radiation flux curves. Using computer software, select historical radiation flux curve data to obtain the thermal radiation flux values ​​at different locations (110 mm, 210 mm, 310 mm, 410 mm, 510 mm, 610 mm, 710 mm, 810 mm, and 910 mm) of the simulated sample during a previous radiation flux curve calibration process.

[0024] Step (4): Create a new radiation flux curve. Place the simulated sample into the test apparatus and wait for the test conditions to stabilize. Then, operate the thermal radiation flux measurement probe and place it at the measurement position corresponding to 110 mm of the simulated sample. After the thermal radiation flux test data stabilizes, operate the computer software to record the thermal radiation flux value at this moment and assign it to F110, with the unit being kW / m². 2 The thermal radiation flux measurement probe was then moved to the measurement position corresponding to 210 mm of the simulated sample. After the test data stabilized, the computer software recorded the thermal radiation flux value at that moment and assigned it to F210, with units of kW / m². 2 Similarly, the thermal radiation flux values ​​at different locations of 310 mm, 410 mm, 510 mm, 610 mm, 710 mm, 810 mm, and 910 mm were obtained, and these values ​​were assigned to F310, F410, F510, F610, F710, F810, and F910, respectively, with units of kW / m².2 Once the simulated sample is removed, the radiation flux curve is established. The computer software synchronously records the blackbody temperature of the radiation plate, the chamber temperature, and the calibration date data during the calibration process.

[0025] Step (5): Start a new test. Place the test flooring material sample into the test apparatus, ignite the test flooring material sample, and begin the test. During the test, record the farthest distance of flame propagation at 10 min, 20 min, and 30 min, and assign the values ​​to S10, S20, and S30 respectively, in mm. At the same time, record the farthest distance of flame propagation when the flame is extinguished and assign the value to SX, in mm.

[0026] Step (6): Calculation of radiation flux data.

[0027] Using the flame propagation distances of S10, S20, S30, and SX as the values ​​of S, and substituting them into the following calculation process, four HF values ​​are obtained and assigned to HF10, HF20, HF30, and HFX, respectively, with units of kW / m. 2 .

[0028] Reference Figure 2 The method for calculating radiation flux data is as follows: a) When S ≤ 110, HF ≥ 11; b) When 110 < S ≤ 210, HF = 0.01·(F110-F210)·(S-110)+F210; c) When 210 < S ≤ 310, HF = 0.01·(F210-F310)·(S-210) + F310; d) When 310 < S ≤ 410, HF = 0.01·(F310-F410)·(S-310) + F410; e) When 410 < S ≤ 510, HF = 0.01·(F410-F510)·(S-410)+ F510; f) When 510 < S ≤ 610, HF = 0.01·(F510-F610)·(S-510) + F610; g) When 610 < S ≤ 710, HF = 0.01·(F610-F710)·(S-610) + F710; h) When 710 < S ≤ 810, HF = 0.01·(F710-F810)·(S-710) + F810; i) When 810 < S ≤ 910, HF = 0.01·(F810-F910)·(S-810)+ F910; j) When 910 < S, HF ≤ 1.1.

[0029] The calculation of radiation flux is complete.

[0030] Step (7): Determination of critical radiative flux. Comparing HF10, HF20, HF30, and HFX, the minimum value, CHF, is taken as the critical radiative flux of this sample, with units of kW / m². 2 .

[0031] Step (8): Determination of critical radiative flux.

[0032] Reference Figure 3 The method for determining the critical radiative flux is as follows: a) When CHF ≥ 8.0, the critical radiation flux of the sample meets the requirements of grades A (A2) and B1 (B); b) When 8.0 > CHF ≥ 4.5, the critical radiation flux of the sample meets the requirements of Class B1 (C). c) When 4.5 > CHF ≥ 3.0, the critical radiation flux of the sample meets the requirements of Class B2 (D). d) When CHF < 3.0, the critical radiation flux of the sample does not meet the requirements of B2(D) level.

[0033] The determination of radiation flux is complete.
