Description

Technical Field

[0001] The invention relates to the technical field of rust-proof oil preparation, in particular to a preparation process of dehydrated rust-proof oil. Background Art

[0002] Dehydration anti-rust oil is an oil product with dual functions of dehydration and rust prevention. It can quickly remove moisture from the metal surface and form a protective film on the metal surface to prevent the metal from rusting. It is widely used in mechanical processing industry, steel industry, hardware industry, electronics industry and other fields.

[0003] At present, the preparation process of dehydrated rust-proof oil generally includes the steps of pre-mixing, thorough mixing, coarse filtration, fine filtration, quality inspection and packaging and storage. Among them, quality inspection is one of the most important steps to verify the dehydrated rust-proof oil. Quality inspection includes many inspection items, among which the anti-rust performance inspection item of dehydrated rust-proof oil is the most important. It is generally tested through salt spray test. The current test process mainly involves placing the sample coated with dehydrated rust-proof oil in a test box, simulating a humid environment according to the set standard, and atomizing salt water to corrode the surface of the sample. Then, the rusting time of the sample is recorded and the rusting state is observed, and the anti-rust performance is evaluated by recording the data.

[0004] However, the above-mentioned anti-rust performance verification process has the following problems: during the current salt spray test, the sample needs to be placed and fixed in the test chamber. The main placement method is to tilt the sample at an angle of 15 to 30 degrees and fix it and then conduct the salt spray test. Although this placement method allows the salt spray to better cover the sample surface, the upper surface of the sample coated with dehydrated rust preventive oil is not always at the above-mentioned tilt angle during actual use. Therefore, the results obtained based on the above-mentioned tilted salt spray test have limitations and low accuracy; secondly, in order to obtain more test data, multiple samples need to be tested, but during the current salt spray test, only a single sample is tested each time. Therefore, in the overall detection process, the steps of sample placement, angle adjustment, and detection need to be repeated many times, and the overall detection efficiency needs to be improved; furthermore, when the tilt angle is a variable, the other test conditions of multiple samples in the same batch are the same. If you want to control other test conditions as variables and increase the test data, the repetition and complexity of the overall detection steps will increase further, which will further affect the overall detection efficiency.

DETAILED DESCRIPTION

[0036] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] like Figure 1 and Figure 2As shown, a preparation process of a dehydrated rust preventive oil includes the following steps: S1, premixing: first, add the base oil into the mixing kettle, start the stirring operation, and the speed is generally controlled at 300-500 rpm; then, add the rust inhibitor, dehydrating agent and additives in sequence according to the formula ratio, and premix under the action of stirring force. During the premixing process, the temperature is controlled at 40-60°C to reduce the viscosity of the materials and promote mixing.

[0038] S2. Thorough mixing: Increase the stirring speed to 600-800 rpm and continue stirring for a certain period of time to fully mix the various ingredients. During the thorough mixing stage, sampling and testing can be used to observe the uniformity of the dehydrated rust preventive oil, such as whether the rust inhibitor is completely dissolved in the base oil and whether the dehydrating agent and additives are evenly dispersed. If undissolved particles or stratification are found, the stirring time needs to be extended or the stirring speed needs to be adjusted.

[0039] S3. Coarse filtration operation: The fully mixed dehydrated rust-proof oil is coarsely filtered through a filter. The mesh number of the coarse filtration operation is generally 80-100 mesh. It is mainly used to remove larger impurity particles in the dehydrated rust-proof oil, such as incompletely dissolved solid additives or foreign impurities. The coarse filtration operation step can preliminarily purify the product and prevent large particles of impurities from causing blockage and other problems in subsequent use.

[0040] S4. Fine filtration: The dehydrated rust-proof oil from the coarse filtration is filtered through a filter screen with a mesh size of 200-300. The fine filtration can remove tiny impurities, colloids, etc., making the appearance of the dehydrated rust-proof oil clearer and more transparent, thereby improving the quality and stability of the product. During the fine filtration process, it is important to maintain a certain pressure and flow rate to avoid clogging of the filter screen and affecting the filtration effect.

[0041] S5. Quality inspection: The dehydrated anti-rust oil after fine filtration is tested for anti-rust performance through salt spray test equipment. The anti-rust performance is evaluated based on the results of the quality inspection. If the anti-rust performance of the product does not meet the standards, the formula or production process needs to be adjusted. After the salt spray test is passed, dehydration performance, viscosity, flash point and pour point tests are also carried out until the product quality meets the standards.

[0042] S6. Packaging and storage: Dehydrated rust-proof oil that has passed quality inspection should be packaged and stored in metal barrels. A special filling machine should be used during packaging to ensure the accuracy of the filling volume. Dehydrated rust-proof oil should be stored in a cool, dry and well-ventilated warehouse. The temperature of the warehouse is generally controlled at 5-35℃ and the humidity does not exceed 70%.

[0043] like Figure 2 and Figure 3As shown, the salt spray test equipment involved in step S5 includes a test box 1, the upper end of the test box 1 is open, and two mounting columns 2 with front-to-back symmetry and vertical axes are fixed on the left and right end surfaces of the test box 1 through fixed blocks. A sealing door 20 for sealing the open end of the test box 1 is installed on all the mounting columns 2 through sliding blocks. An external electric push rod (not shown in the figure) is provided between the sealing door 20 and the test box 1.

[0044] like Figure 2 、 Figure 3 and Figure 4 As shown, the test box 1 and the sealing door 20 are jointly provided with a clamping mechanism 3 for clamping and locking all templates, and the clamping mechanism 3 includes an arc-shaped plate 30, and the arc-shaped plates 30 are fixedly provided in the test box 1 and under the sealing door 20, and the inner arc surfaces of the two arc-shaped plates 30 are opposite to each other, and the inner arc surfaces of the arc-shaped plates 30 are rotatably provided with a plurality of pressure plate seats 300 arranged equidistantly from left to right. The two pressure plate seats 300 opposite to each other clamp and lock the corresponding templates after closing, and the test box 1 is provided with an adjustment unit 32 for independently adjusting the inclination angle of the clamped template, and the adjustment unit 32 includes a pulling rod 320, and the front end of the test box 1 is provided with a pulling rod 320 corresponding to the pressure plate seat 300 on the lower arc plate 30 for sliding back and forth, and the rear end face of the pulling rod 320 is fixedly provided with an implementation plate 321.

[0045] like Figure 2 、 Figure 3 and Figure 4 As shown, the test box 1 also includes a test unit 4, and the test unit 4 includes a partition plate 1 40. A partition plate 1 40 is fixedly provided between the lower arc plate 30 and the bottom wall of the inner cavity of the test box 1. A partition plate 2 41 is fixedly provided on the outer arc surface of the upper arc plate 30. The partition plate 2 41 slides up and down through the sealing door 20. The partition plate 1 40, the partition plate 2 41 and all the pressure plate seats 300 cooperate with each other. After the clamping mechanism 3 completes the clamping, the test box 1 is divided into two front and rear test chambers. Two groups of operating equipment are provided in the test box 1, which are respectively located in the two test chambers. The operating equipment includes a heater and a spray equipment (the operating equipment is prior art and is not shown in the figure).

[0046] During operation, first, multiple samples (coated with dehydrated anti-rust oil) are manually placed on the pressure plate seat 300 at the corresponding position on the lower curved plate 30, and the external electric push rod is operated to move the sealing door 20 and the upper curved plate 30 downward. Finally, the two upper and lower pressure plate seats 300 are closed to clamp and fix the samples. Then, the adjustment unit 32 is used to make the multiple samples have different inclination angles (for example, the leftmost sample is horizontal, and the remaining samples are tilted at different angles from left to right), so that multiple groups of control groups with different inclination angles are formed. At the same time, the front and rear cavities are separated by partition plate 1 40 and partition plate 2 41. By controlling the heaters in the front and rear cavities to operate, the temperature in the two cavities simulates the specified temperature in a humid environment. At the same time, the spray equipment is operated to form salt water into a spray and spray it into the corresponding cavity, thereby performing a salt spray test on the samples. After the test, all samples are taken out, and the anti-rust performance is evaluated by recording the time when the samples rust and observing the rust state.

[0047] It should be noted that the temperatures in the two cavities are different because the heaters in the two test cavities work separately, but the operating conditions of the spray equipment are the same at this time. Therefore, the front and rear cavities form a control group of the salt spray test under different temperature conditions. Secondly, the spray volume in the two cavities is controlled to be different by the spray equipment, but the heating temperature of the heater is the same at this time. Therefore, the front and rear cavities form a control group of the salt spray test under different spray volume conditions. At the same time, salt spray control tests with different inclination angles are combined to realize control experiments under various conditions, improve the test efficiency and the matching degree with the actual usage conditions, and thus improve the reliability of the test results.

[0048] like Figure 3 、 Figure 4 and Figure 5 As shown, the clamping mechanism 3 also includes a placement groove 301. The placement groove 301 is formed on the opposing surfaces of the two corresponding upper and lower pressure plate seats 300, and a rubber pad 302 is fixedly installed in the placement groove 301. The upper end surface of the lower pressure plate seat 300 is formed with two docking grooves 303, and the two docking grooves 303 are respectively located on the left and right sides of the corresponding placement groove 301. The lower end surface of the upper pressure plate seat 300 is fixedly provided with docking blocks 304 corresponding to the docking grooves 303. The lower ends of the docking blocks 304 are chamfered.

[0049] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, the clamping mechanism 3 also includes an auxiliary group arranged on the lower pressure plate seat 300, and the auxiliary group includes an elastic strip 31. Two elastic strips 31 distributed left and right are fixedly provided on the front and rear end surfaces of the lower pressure plate seat 300, and the elastic strip 31 is located below the corresponding placement groove 301. A clamping block 310 is fixedly provided at one end of the elastic strip 31 away from the corresponding pressure plate seat 300, and the upper end surface of the clamping block 310 is inclined from top to bottom toward the direction close to the pressure plate seat 300.

[0050] In the process of placing the templates, multiple templates are first placed manually in the placement grooves 301 corresponding to the lower pressure plate seat 300. At this time, through the mutual cooperation between the four elastic strips 31 and the four clamping blocks 310 corresponding to the pressure plate seat 300, the templates are initially clamped and supported, which facilitates the subsequent clamping and limiting of the templates.

[0051] Afterwards, the external electric push rod works to move the sealing door 20 downward, and the sealing door 20 drives all the upper pressure plate seats 300 to move downward synchronously, and gradually begins to engage and close with the lower pressure plate seat 300. During this process, the docking block 304 on the upper pressure plate seat 300 is gradually stuck in the corresponding lower docking groove 303, guiding the downward movement of the upper pressure plate seat 300. Finally, the two corresponding upper and lower pressure plate seats 300 are closed, and the sample located between the two is clamped and locked. The rubber pad 302 is provided to improve the sealing effect of the gap between the placement groove 301 and the sample, to ensure the partition effect between the front and rear test chambers, to avoid the two test chambers interfering with each other due to poor sealing effect in the middle, affecting the test results, and at the same time, it also strengthens the limiting effect of the sample to prevent the sample from sliding or falling off.

[0052] like Figure 2 、 Figure 3 and Figure 4 As shown, the test unit 4 also includes a sliding groove 42. The left and right end surfaces of the test box 1 are both provided with sliding grooves 42. The upper curved plate 30 is slidably set in the sliding groove 42. The upper end surface of the upper curved plate 30 is fixedly provided with a blocking block 420 corresponding to the sliding groove 42 one by one. The front and rear end surfaces and the upper end surface of the blocking block 420 are both provided with a sealing strip 421 made of rubber material.

[0053] like Figure 2 、 Figure 4 and Figure 5 As shown, two guide grooves 422 distributed left and right are provided on both the front and rear end surfaces of the upper curved plate 30 . The two front and rear opposite guide grooves 422 cooperate with the inner wall of the sliding groove 42 to guide the movement of the upper curved plate 30 .

[0054] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, the test unit 4 further includes a connecting platform 43 , and the upper end surface of the second partition plate 41 is fixed with the connecting platform 43 via a fixing rod. A plurality of springs 430 arranged in a rectangular shape are fixedly provided between the connecting platform 43 and the sealing door 20 .

[0055] During operation, after all samples are placed, the external electric push rod works to move the sealing door 20 downward, and the sealing door 20 drives the partition plate 2 41, the upper arc plate 30 and all the upper pressure plate seats 300 to move downward synchronously. The upper pressure plate seat 300 moves down and presses the sample and then stops moving. As the sealing door 20 continues to move downward to the upper end of the test box 1 and the sealing block 420 are tightly attached, the test box 1 is closed, and at the same time, the upper pressure plate seat 300 completes the rigid tightening of the corresponding sample, thereby completing the compression limit of the sample.

[0056] Secondly, in the above process, the upper curved plate 30 drives the sealing block 420 to move into the sliding groove 42. When the sealing door 20 and the upper end of the test box 1 are closed, the upper end of the sealing block 420 is flush with the upper end of the test box 1, completing the sealing of the upper end of the test box 1. During this process, the provided sealing strip 421 is deformed to seal the gap between the sealing block 420 and the inner wall of the sliding groove 42, ensuring the sealing effect of the two test chambers during the test. At the same time, the downward movement of the curved plate 30 is guided by the guide groove 422 to guide the subsequent closing and clamping process of the template between the upper pressure plate seat 300 and the lower pressure plate seat 300, and cooperate with the guidance between the docking block 304 and the docking groove 303 to ensure that the upper and lower pressure plate seats 300 can be accurately docked, which is conducive to ensuring the sealing effect after the two are docked.

[0057] like Figure 2 、 Figure 3 、 Figure 6 and Figure 7 When the locking plate 323 is unlocked, the locking plate 323 is unlocked and the locking plate 324 is unlocked, and the cam 324 is unlocked, so that the cam 324 can be unlocked. When the locking plate 323 is unlocked, the locking plate 323 is unlocked and the locking plate 324 is unlocked. The cam 324 is unlocked and the locking plate 324 is unlocked.

[0058] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, the adjustment unit 32 also includes a pre-locking group 33 arranged in the test box 1, and the pre-locking group 33 includes a U-shaped frame 330. A frame group corresponding to the implementation plate 321 is fixedly provided in the test box 1, and the frame group includes two U-shaped frames 330 located on the left and right sides of the implementation plate 321 and symmetrical on the left and right sides. The left and right end surfaces of the implementation plate 321 are provided with a plurality of semicircular grooves 331 equidistantly arranged from front to back. A plurality of rubber-made locking balls 332 equidistantly arranged front to back are fixedly provided on the vertical section of the U-shaped frame 330. The spacing between adjacent locking balls 332 is the same as the spacing between adjacent semicircular grooves 331, and a cavity is provided inside the upper half of the upper pressure plate seat 300.

[0059] During operation, after the sealing door 20 moves downward so that the upper pressure plate seat 300 presses the sample, the tilt angle of the sample is manually adjusted according to the test needs. The specific process is as follows: manually pull the locking plate 323 corresponding to the corresponding pressure plate seat 300, so that the locking plate 323 drives the pulling rod 320 and the implementation plate 321 to move backward. The implementation plate 321 moves backward and tilts the corresponding pressure plate seat 300 through the hinge bar 322. During the above process, as the implementation plate 321 moves, the locking ball 332 moves out of the original semicircular groove 331 and is locked into the adjacent semicircular groove 331 at the rear. It should be noted that in the initial state, the locking ball 332 is locked in the corresponding semicircular groove 331, and the pre-locking of the implementation plate 321 is achieved through the cooperation between the locking ball 332 and the semicircular groove 331. The distance between two adjacent locking grooves 324 is an integer multiple of the distance between two adjacent semicircular grooves 331. Therefore, when the locking plate 323 is manually moved to adjust the inclination angle of the lower pressure plate seat 300, when any locking groove 324 on the locking plate 323 is relative to the corresponding locking bar 326, the locking ball 332 can be located in the corresponding semicircular groove 331, ensuring the pre-locking function of the locking ball 332, so as to improve the position stability of the template at the current angle before the locking groove 324 and the locking plate 323 are engaged.

[0060] Repeat the above adjustment process so that each sample has a set inclination angle. As the external electric push rod continues to operate, the sealing door 20 continues to move downward. The sealing door 20 drives all the locking bars 326 to move downward synchronously through the lifting frame 325, so that the locking bar 326 is inserted into the opposite locking groove 324 directly below it, limiting the position of the locking plate 323 and the angle of the pressure plate seat 300, and then the salt spray test is carried out.

[0061] It should be noted that after completing the salt spray test, the sealing door 20 moves up, so that the upper pressure plate seat 300 elastically presses the corresponding template, and the locking bar 326 exits the locking groove 324, and then the locking plate 323 is manually moved, so that the lower pressure plate seat 300 drives the upper pressure plate seat 300 to reset, and the sealing door 20 moves up again to drive all the upper pressure plate seats 300 to reset synchronously. The upper pressure plate seat 300 has a cavity in the upper half and its overall center of gravity is biased downward. Therefore, when the clamping operation is not performed, the upper pressure plate seat 300 is always vertically downward (the docking block 304 on it is vertically downward), which is convenient for docking and closing between the upper and lower pressure plate seats 300.
