Description

Technical Field

[0001] The present invention relates to the technical field of anti-rust oil preparation, and particularly to a preparation process of dehydrating anti-rust oil. Background Art

[0002] Dehydrating anti-rust oil is an oil product with dual functions of dehydration and rust prevention. It can quickly remove the moisture on the metal surface, and at the same time form a protective film on the metal surface to prevent the metal from rusting. It is widely used in fields such as the machining industry, the steel industry, the hardware products industry, and the electronics industry.

[0003] Currently, the preparation process of dehydrating anti-rust oil generally includes steps such as premixing, thorough mixing, rough filtration operation, fine filtration operation, quality inspection, and packaging and storage. Among them, quality inspection is one of the most important steps to verify dehydrating anti-rust oil. Quality inspection includes many inspection items, and among them, the anti-rust performance inspection item of dehydrating anti-rust oil is the most important. It is generally tested through a salt spray test. The current test process is mainly to place the sample coated with dehydrating anti-rust oil in the test chamber, simulate a humid environment according to the set standard, atomize the brine to corrode the surface of the sample, and then record the rusting time of the sample and observe the rusting state, and evaluate the anti-rust performance by recording data.

[0004] However, the above anti-rust performance verification process has the following problems: In the current salt spray test process, the sample needs to be placed and fixed in the test chamber. Its main placement method is to place the sample in an inclined manner at an angle of 15 degrees to 30 degrees and fix it firmly, and then conduct the salt spray test. Although this placement method enables the salt spray to better cover the sample surface, in the actual use process of the sample coated with dehydrating anti-rust oil, its upper surface is not always in the above inclined angle. Therefore, the results obtained from the salt spray test based on the above inclined placement have limitations and low accuracy; secondly, in order to obtain more test data, multiple samples need to be tested. However, in the current salt spray test process, only a single sample is tested each time. Therefore, in the overall detection process, steps such as placing the sample, adjusting the angle, and detecting need to be repeated multiple times, and the overall detection efficiency needs to be improved; furthermore, when the inclined angle is a variable, and 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 test data, the repetition and complexity of the overall detection steps will further increase, and then further affect the overall detection efficiency.

Detailed implementation manners

[0036] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0037] Such as Figure 1 And Figure 2As shown in the figure, a preparation process of dehydrating antirust oil includes the following steps: S1. Premixing: First, add the base oil into the blending kettle, start the stirring operation, and generally control the rotation speed at 300 - 500 revolutions per minute; then add the antirust agent, dehydrating agent, and additive in sequence according to the formula ratio, and perform premixing under the action of the stirring force. During the premixing process, control the temperature at 40 - 60 °C to reduce the viscosity of the material and promote mixing.

[0038] S2. Thorough mixing: Increase the stirring speed to 600 - 800 revolutions per minute and continuously stir for a certain period of time to make all components mix evenly. During the thorough mixing stage, the uniformity of the dehydrating antirust oil can be observed by sampling and testing. For example, check whether the antirust agent is completely dissolved in the base oil, and whether the dehydrating agent and additive 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 dehydrating antirust oil after thorough mixing is coarsely filtered through a filter screen. The mesh number of the filter screen for the coarse filtration operation is generally 80 - 100 meshes, mainly to remove larger impurity particles in the dehydrating antirust oil, such as undissolved solid additives or foreign impurities. The coarse filtration operation step can initially purify the product and prevent problems such as blockage caused by large particle impurities during subsequent use.

[0040] S4. Fine filtration operation: The dehydrating antirust oil from the coarse filtration operation is finely filtered through a filter screen. The mesh number of the filter screen for the fine filtration operation is 200 - 300 meshes. The fine filtration operation can remove tiny impurities, gums, etc., making the appearance of the dehydrating antirust oil clearer and more transparent, and improving the quality and stability of the product; during the fine filtration process, it is necessary to pay attention to maintaining a certain pressure and flow rate to avoid filter screen blockage affecting the filtration effect.

[0041] S5. Quality inspection: The dehydrating antirust oil after the fine filtration operation is subjected to an antirust performance test through a salt spray test device, and the antirust performance is evaluated according to the results of the quality inspection. If the antirust performance of the product does not meet the standard, the formula or production process needs to be adjusted; after passing the salt spray test, other test items such as dehydration performance, viscosity, flash point, and pour point are also carried out until the product quality meets the standard.

[0042] S6. Packaging and storage: The dehydrating antirust oil with qualified quality inspection is packaged and stored in metal barrels. A special filling machine should be used during packaging to ensure accurate filling volume; the dehydrating antirust oil should be stored in a warehouse with a cool, dry, and well-ventilated environment. The temperature of the warehouse is generally controlled at 5 - 35 °C, and the humidity does not exceed 70%.

[0043] As Figure 2 and Figure 3As shown, the salt spray test equipment involved in step S5 includes a test chamber 1. The upper end of the test chamber 1 is open. Both the left and right end faces of the test chamber 1 are fixedly provided with two vertically axisymmetric mounting columns 2 that are symmetric front and back through fixing blocks. A sealing door 20 for blocking the open end of the test chamber 1 is slidably mounted up and down on all the mounting columns 2 through sliding blocks. An external electric push rod (not shown in the figure) is commonly provided between the sealing door 20 and the test chamber 1.

[0044] As Figure 2 , Figure 3 and Figure 4 shown, a clamping mechanism 3 for clamping and locking all the templates is commonly provided on the test chamber 1 and the sealing door 20. The clamping mechanism 3 includes an arc-shaped plate 30. Arc-shaped plates 30 are fixedly provided both inside the test chamber 1 and below the sealing door 20. The inner arc surfaces of the two arc-shaped plates 30 face each other up and down. A plurality of pressing plate seats 300 arranged at equal intervals from left to right are rotatably provided on the inner arc surface of the arc-shaped plate 30. The two pressing plate seats 300 that face each other up and down clamp and lock the corresponding template after closing. The test chamber 1 is provided with an adjusting unit 32 for independently adjusting the inclination angle of the clamped template. The adjusting unit 32 includes a pulling rod 320. Pulling rods 320 corresponding to the pressing plate seats 300 on the lower arc-shaped plate 30 are slidably arranged back and forth on the front end surface of the test chamber 1. An implementation plate 321 is fixedly provided on the rear end surface of the pulling rod 320.

[0045] As Figure 2 , Figure 3 and Figure 4 shown, the test chamber 1 further includes a test unit 4. The test unit 4 includes a partition plate one 40. A partition plate one 40 is commonly fixedly provided between the lower arc-shaped plate 30 and the bottom wall of the inner cavity of the test chamber 1. The outer arc surface of the upper arc-shaped plate 30 is fixedly provided with a partition plate two 41. The partition plate two 41 slides up and down through the sealing door 20. The partition plate one 40, the partition plate two 41, and all the pressing plate seats 300 cooperate with each other to divide the test chamber 1 into two front and rear test chambers after the clamping mechanism 3 completes clamping. Two sets of working devices located in the two test chambers respectively are provided in the test chamber 1. The working devices include a heater and a spraying device (the working devices are prior art and not shown in the figure).

[0046] During operation, first, multiple templates (coated with dehydrating antirust oil) are manually placed on the pressure plate seats 300 at corresponding positions on the lower arc-shaped plate 30. The external electric push rod works to lower the sealing door 20 and the upper arc-shaped plate 30. Eventually, the two pressure plate seats 300 facing each other up and down close together to clamp and fix the templates. Then, through the adjustment unit 32, the multiple templates are set at different inclination angles (for example, the leftmost template is horizontal, and the remaining templates are inclined at different angles from left to right in sequence). Therefore, multiple control groups with only different inclination angles are formed. At the same time, the front and rear cavities are separated by the first partition plate 40 and the second partition plate 41. By controlling the heaters in the front and rear cavities for operation, the temperatures in the two cavities are simulated to the specified temperatures in a humid environment. At the same time, the spraying equipment works to make the brine form a spray and spray it into the corresponding cavity, so as to conduct a salt spray test on the templates. After the test is completed, all the templates are taken out, and the rust prevention performance is evaluated by recording the rusting time of the templates and observing the rusting state.

[0047] It should be noted that the heaters in the two test cavities work separately to make the temperatures in the two cavities different, but at this time the operation conditions of the spraying equipment are the same. Therefore, the front and rear cavities form control groups for salt spray tests under different temperature conditions. Secondly, by controlling the spraying amounts in the two cavities by the spraying equipment to be different, but at this time the heating temperatures of the heaters are the same. Therefore, control groups for salt spray tests under different spraying amounts are formed in the front and rear cavities. At the same time, in cooperation with the salt spray control tests with different inclination angles, control experiments in multiple situations are realized, the test efficiency and the matching degree with the actual use situation are improved, and further the reliability of the test results is improved.

[0048] As Figure 3 、 Figure 4 and Figure 5 As shown in

[0049] As Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, the clamping mechanism 3 further includes an auxiliary group disposed on the lower platen base 300. The auxiliary group includes elastic strips 31. Two elastic strips 31 distributed left and right are fixedly provided on the front and rear end faces of the lower platen base 300, and the elastic strips 31 are located below the corresponding placement grooves 301. A clamping block 310 is fixedly provided at one end of the elastic strip 31 away from the corresponding platen base 300. The upper end face of the clamping block 310 inclines downward from top to bottom towards the direction close to the platen base 300.

[0050] During the process of placing the templates, first, multiple templates are manually placed in the corresponding placement grooves 301 of the lower platen base 300 respectively. At this time, through the mutual cooperation between the four elastic strips 31 and the four clamping blocks 310 corresponding to the platen base 300, the templates are initially clamped and preliminarily supported at the same time, facilitating subsequent re-clamping and limiting of the templates.

[0051] After that, the external electric push rod works to move the sealing door 20 downward. The sealing door 20 drives all the upper platen bases 300 to move downward synchronously and gradually begins to dock and close with the lower platen base 300. During this process, the docking blocks 304 on the upper platen base 300 are gradually inserted into the corresponding lower docking grooves 303 to guide the downward movement process of the upper platen base 300. Finally, the two corresponding upper and lower platen bases 300 are closed, and the templates located between them are clamped and locked. The rubber pads 302 provided improve the sealing effect of the gap between the placement groove 301 and the template, ensure the partition effect between the front and rear test chambers, avoid the problem that the two test chambers interfere with each other due to poor intermediate sealing effect, affect the test results, and at the same time strengthen the limiting effect on the template to prevent the template from sliding or falling off.

[0052] As Figure 2 、 Figure 3 and Figure 4 shown, the test unit 4 further includes sliding grooves 42. Sliding grooves 42 are opened on the left and right end faces of the test chamber 1. The upper arc-shaped plate 30 is slidably disposed in the sliding grooves 42. A blocking block 420 corresponding to the sliding grooves 42 is fixedly provided on the upper end face of the upper arc-shaped plate 30. Rubber sealing strips 421 are provided on the front, rear, and upper end faces of the blocking block 420.

[0053] As Figure 2 、 Figure 4 and Figure 5 shown, two guiding grooves 422 distributed left and right are opened on the front and rear end faces of the upper arc-shaped plate 30. The two relatively front and rear guiding grooves 422 cooperate with the inner walls of the sliding grooves 42 to guide the movement of the upper arc-shaped plate 30.

[0054] As Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, the test unit 4 further includes a connecting platform 43 , and the connecting platform 43 is fixedly provided on the upper end surface of the second partition plate 41 via a fixing rod, and 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 operates 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 and limiting 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. In 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, thereby 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, thereby guiding the subsequent process of closing and clamping the sample between the upper pressure plate seat 300 and the lower pressure plate seat 300, and cooperating with the guidance between the docking block 304 and the docking groove 303, thereby ensuring that the upper and lower pressure plate seats 300 can be accurately docked, thereby ensuring the sealing effect after the two are docked.

[0057] like Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the adjustment unit 32 also includes a hinge bar 322, and the rear end of the implementation plate 321 is rotatably provided with a hinge bar 322, and the hinge bar 322 is hingedly provided on the corresponding pressure plate seat 300 on the lower side, and the front end face of the pull rod 320 is fixedly provided with a locking plate 323, and the upper end of the locking plate 323 is provided with a plurality of locking grooves 324 arranged equidistantly from front to back, and the front end face of the sealing door 20 is fixedly provided with a lifting frame 325 through an L-shaped frame, and the lower end face of the lifting frame 325 is fixedly provided with a locking bar 326 corresponding to the locking plate 323 one by one, and the lower end of the locking bar 326 is chamfered, the locking groove 324 is an inverted right-angled trapezoid, and the rear inner wall of the locking groove 324 is an inclined surface.

[0058] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the adjusting unit 32 further includes a pre-locking group 33 disposed in the test chamber 1. The pre-locking group 33 includes a U-shaped frame 330. A frame group corresponding to the implementation plate 321 one by one is fixedly arranged in the test chamber 1. The frame group includes two U-shaped frames 330 that are symmetric left and right and located on the left and right sides of the implementation plate 321. A plurality of semi-circular grooves 331 arranged at equal intervals from front to back are formed on the left and right end faces of the implementation plate 321. A plurality of rubber material clamping balls 332 arranged at equal intervals from front to back are fixedly arranged on the vertical section of the U-shaped frame 330. The distance between adjacent clamping balls 332 is the same as the distance between adjacent semi-circular grooves 331. A cavity is arranged inside the upper half section of the upper pressing plate seat 300.

[0059] During operation, after the lower movement of the sealing door 20 causes the upper pressing plate seat 300 to press the sample plate, an operator adjusts the inclination angle of the sample plate according to the test requirements. The specific process is as follows: The operator pulls the locking plate 323 corresponding to the corresponding pressing plate seat 300, so that the locking plate 323 drives the pulling rod 320 and the implementation plate 321 to move backward. The backward movement of the implementation plate 321 causes the corresponding pressing plate seat 300 to tilt through the hinge strip 322. During the above process, as the implementation plate 321 moves, the clamping ball 332 moves out of the original semi-circular groove 331 and is clamped into the adjacent semi-circular groove 331 behind. It should be noted that in the initial state, the clamping ball 332 is clamped in the corresponding semi-circular groove 331, and the pre-locking of the implementation plate 321 is realized through the cooperation between the clamping ball 332 and the semi-circular groove 331. The distance between adjacent two locking grooves 324 is an integer multiple of the distance between adjacent two semi-circular grooves 331. Therefore, when the operator moves the locking plate 323 to adjust the inclination angle of the lower pressing plate seat 300, when any locking groove 324 on the locking plate 323 is vertically opposite to the corresponding locking strip 326, the clamping ball 332 can be located in the corresponding semi-circular groove 331, ensuring the pre-locking function of the clamping ball 332, so as to improve the position stability of the sample plate at the current angle before the locking groove 324 and the locking plate 323 are clamped.

[0060] Repeat the above adjustment process so that each sample plate 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 strips 326 to move downward synchronously through the lifting frame 325, so that the locking strips 326 are inserted into the locking grooves 324 directly below them, limiting and locking the position of the locking plate 323 and the angle of the pressing plate seat 300, and then the salt spray test is carried out.

[0061] It should be noted that after the salt spray test is completed, the sealing door 20 moves upward, so that the upper pressing plate seat 300 elastically presses the corresponding template, and the locking bar 326 exits the locking groove 324. Then, the locking plate 323 is manually moved, so that the lower pressing plate seat 300 drives the upper pressing plate seat 300 to reset. The sealing door 20 moves upward again to drive all the upper pressing plate seats 300 to reset synchronously. Since the upper half of the upper pressing plate seat 300 is provided with a cavity, the overall center of gravity is biased downward. Therefore, when no clamping operation is performed, the upper pressing plate seat 300 always faces vertically downward (the docking block 304 thereon faces vertically downward), which is convenient for docking and closing between the upper and lower pressing plate seats 300.
