In recent years, with the development of science and technology and industry, the acrylic mirror industry is more and more mature, and the application range is also very wide. But now the quality of acrylic materials on the market is uneven, good quality acrylic, and poor quality acrylic, there is still a big difference in the use of.   1. Visual observation method   This is based on the material characteristics of acrylic itself to judge, acrylic light transmittance can reach more than 92%, pay attention to the following points when buying:   1) Whether the acrylic sheet has serious fading   2) How is the gloss of acrylic sheet   3) How light transmittance of acrylic sheet   If there are the above three problems, it means that the quality of acrylic sheet is relatively inferior.   Second, the transmittance observation method   The light transmittance of acrylic can reach more than 92%, and the light color after passing through the acrylic sheet is the same as the original light color.   Use a flashlight with positive white light to illuminate the acrylic (because positive white light is better to distinguish), if the color of the light through the blue or yellow words, it indicates that the quality of the acrylic plate is relatively inferior.   Third, hot melt paste method   The adhesive degree of good quality acrylic plate and poor quality acrylic plate is not the same, the good quality acrylic plate is easily separated after hot melt, and the poor quality acrylic plate is not easy to separate after hot melt.   4. Ignition method   One of the characteristics of acrylic: flame retardant. Before purchasing, you can ask the manufacturer for a few more samples and test with small samples.   Ignite the sample, if the sample is easy to burn up, it means that the quality of the acrylic plate is not good. Because good quality acrylic is not easy to light.   5. Touch the Law   The more direct way, just touch it, see how it feels.   If you feel the feeling of lime, feel the dust, look closely and there are some small pits, then this must be a poor quality acrylic plate   High quality acrylic sheet, feel creamy, and the surface is smooth and flat.

1. Raw material management   The storage place of rubber raw materials must be kept dry, clean, no debris, no oil; Store in a cool and ventilated place during high temperature in summer. Before all rubber materials are stored, the appearance, hardness and humidity of rubber raw materials must be checked, and recorded and archived. After confirming the qualification, production can be carried out. Natural and synthetic rubber have very low moisture content, such as moisture content. 1% (typical value is 0.20%~0.40%MC, and some moisture content is even lower), if the moisture is too high, it will have a significant impact on the production molding process. When storing rubber raw materials, it should be 20~25cm from the ground and more than 30cm from the wall.   2. Warehouse management   The finished product warehouse shall be protected against moisture, mildew, lightning and pollution. When storing rubber products, they should be classified and placed in positioning codes, 20~25cm from the ground, 30cm from the wall, and there are obvious classification signs. The temperature and humidity in the warehouse should meet the storage requirements of the products. If conditions are best equipped with dehumidifier. Storage according to the product instructions of rubber parts, avoid direct sunlight, heat, moisture and do not contact with solvent oil, lubricating oil and other solid materials, storage temperature is generally between 0-25℃. Proper ventilation. When the outdoor temperature or humidity is greater than the indoor, it is not appropriate to open the window for ventilation. Enter and exit the warehouse according to the principle of first in first out.   3. Transportation management   When loading container trucks, use an appropriate amount of dry container desiccant on the hooks inside the container trucks to ensure that the tires are not affected by moisture and mildew during transportation.

First, rubber raw glue   The formulation of high hardness rubber often requires a large amount of filling and reinforcing agent, and the selection of raw rubber should choose the brand of high Mooney viscosity. For example, EPDM should choose a brand with high Mooney and high ethylene content; NBR can choose high Menni, high acrylonitrile content brand. Sometimes according to the needs of other properties, you can choose to use high and low Mooney glue, low Mooney glue is not conducive to a large number of filling.   Second, reinforcing filler   Reinforcing with carbon black and white carbon black is the best choice, the comprehensive performance of the two is better, the ability to increase hardness is strong, and the effect of fine particle carbon black is the best, but high hardness rubber material needs a lot of filling, if you use fine particle carbon black alone, rubber mixing, vulcanization and other processes will have serious problems, so fine particle carbon black and large particle carbon black combined use the best effect. Such as N330/N550 collocation. Other weak reinforcing fillers should not be used as far as possible, because these fillers have a weak ability to increase hardness, and a larger number of fillers are needed to achieve the target hardness than carbon black and white carbon black, resulting in a decline in the comprehensive performance of the rubber and the process performance.   Third, plasticizer   High hardness compound requires a lot of filling reinforcing agent, resulting in rubber mixing, vulcanization and other process problems, the right amount of plasticizer or to add, although the plasticizer will reduce the hardness of the compound. The selection of plasticizers is appropriate for solid plasticizers, such as solid coumaron.   Fourth, curing agent   Increasing the crosslinking density of the compound is beneficial to improving the hardness of the compound. For sulfur vulcanization system, increasing the amount of accelerators, especially TMTD accelerators, is conducive to improving the hardness. The increase in the amount of vulcanization can also improve the cross-linking density and enhance the hardness of the rubber, such as when the amount of sulfur reaches 30 to 50 mass parts, hard rubber can be prepared, but when the amount of sulfur and the amount of accelerator are increased, it is easy to produce frosting phenomenon, and the amount needs to be balanced. In addition, for sulfur vulcanization system, high hardness rubber due to high filling, mixing and vulcanization processing heat increase, easy to cause scorch phenomenon, so for the sake of insurance, with anti-scorch agent is also of great benefit, such as CTP. Silicone foam board For the peroxide vulcanization system, increasing the amount of peroxide can improve the hardness, but not too high, you can choose a variety of peroxide vulcanization agents and use, in addition to the addition of crosslinking agents can significantly improve the cross-linking density of the rubber, such as DCP vulcanization agent, can add TAIC, PDM (HVA-2), TAC, PL-400 (TMPTMA), Of course, sulfur can also be used as a cross-linking agent.
