Do you know enough about the use of blind spots for sealing silicone hoses?baby nipple bottle Vendor

　　It is well known that all silicone products are not completely free of defects, such as the commonly used silicone tube strips for sealing, protection and normal use, but when using silicone hoses, there are also defects caused by human factors in addition to normal use, such as the tight assembly of the product. degree, the normal environmental adaptability of the product or the selection of the use conditions of the product, and the consistent use of the product is likely to cause the performance of the silicone tube silicone strip to decline, and the product cannot achieve the expected actual effect!

　　Matters needing attention when using silicone hoses

　　1. The silicone hose has a good bending function in use, the bendable radius is small, and it will not be pleated when it is bent. Therefore, in order to prevent the temperature from being too high and not overloading for a long time, pay attention to the radiator fins not to be polluted by oil, so that the dust-proof soil adheres to affect the heat dissipation; insist on a sufficient amount of oil to facilitate the circulation of oil for heat dissipation. For pressure inspection, the national standard requires that the test pressure is 2 times the working pressure, and the explosion pressure is usually 3-4 times the working pressure to be qualified.

　　2. Look at the brightness of the cross section on the surface of the silicone hose, the one with high brightness is the top grade, and it is better to pinch the rubber with good elasticity. During the movement or interruption, the silicone hose should not be bent excessively, nor at the root. It should be initially bent at least 1.5 times its diameter. In addition, when the high-pressure hose moves to the extreme position, it should not be pulled too tightly. slack.

　　3. During use, the silicone hose should be prevented from being altered and deformed as much as possible. The silicone hose should be kept as far away as possible from the heat radiation components. If necessary, a heat shield can be added to prevent the external damage of the silicone hose. For example, the long-term conflict with the surface of the component during use, etc.; the viscosity of the oil decreases, which may easily lead to leakage, power loss, and lubricating oil film strength, which accelerates mechanical wear and generates carbides and silt; oil oxidation accelerates oil quality deterioration, oil seal , Premature aging of high-pressure hose, etc.

　　4. When cleaning or sterilizing the silicone hose, it can be cleaned with bleach or with a short-term steam disinfection or hot water with a temperature of over 150°C. If you use a disinfectant for cleaning, try to choose a disinfection that has no smell or a faint fruity smell. liquid.

　　5. Most of the EPDM sealing strips are black, and occasionally gray, which is very monotonous. There are many colors of silicone products, such as red, orange, yellow, green, blue, purple, and purple.

　　6. The heat resistance and cold resistance are different; the temperature resistance range of EPDM is -40℃-150℃, while the weakest high temperature vulcanized silicone rubber can withstand -60℃-250℃, not to mention those awesome ones. Specially adjusted silicone rubber high temperature resistant glue and so on.

　　7. The weather resistance is different; due to the different constituent materials, the silicon-oxygen bond of the high temperature vulcanized silicone rubber sealing strip has more advantages in weather resistance than the carbon-carbon bond of EPDM. No way this is the genetic advantage of the silicone material itself.

　　8. The compressive capacity is different; the silicone rubber sealing strip has good elasticity during use. No matter how much pressure falls on us, we can recover the resulting deformation. There are many other rubber materials in terms of flexion and extension. Still incomparable.

　　9. The biocompatibility is different; silicone rubber products have stronger affinity with human friends and get along more friendly, so silicone rubber has environmental protection and green performance, and the application fields are wider, such as medical equipment, food and other fields. As for the figure, this is something that only silicone materials can't do for rubber.

　　10. Materials such as silicone rubber sealing tube sealing strips are all made of 110 raw rubber through banburying, which is also the skeleton part of the silicone rubber sealing strip, and most of its performance and advantages benefit from it. Its molecular weight is between 400,000 and 600,000, with a large amount of methyl groups and a small amount of vinyl functional groups in the middle. In addition, white carbon black is used as the main filler and 101 raw rubber is combined with each other in the appropriate additive component of hydroxy silicone oil to achieve silica gel The raw material of the product is a process in which the material is made into a sealing strip through high temperature vulcanization.
