What are the factors that affect the quality of Insulation Tubes?

The raw material of the Insulation Tubes is silicone rubber, which is a product made of silicone rubber after certain procedures and in accordance with industry requirements. Its appearance is generally translucent, with black, red, white and other colors, and it can withstand high temperature and low temperature. It is a new type of polymer material, which is not easy to deform under strong pressure and has strong plasticity.

When the Insulation Tubes is mixing rubber, the rubber that needs to be tested for density is the rubber that has been vulcanized, because the density of the unvulcanized rubber is not accurate due to the problem of porosity, and there is no density before vulcanization and the density of the mixed rubber. Density belongs to the apparent density, and the density itself has a relatively large error, so the test density needs to be tested with vulcanized rubber when mixing rubber. As for the problems of many air bubbles and pores after the compound rubber is pressed, you can use the assumption that the solid is incompressible, and measure the density of the vulcanized rubber and the compound rubber to obtain the porosity, and then use a small open refining thin pass several times to drive out the air bubbles. , and then vulcanized.
1. If the quality of silicone raw materials is not good, the performance is too poor, and the toughness is not good, then it will easily cause cracks, so the silicone raw materials must be carefully checked.
2. The Silicone Glass Fiber Tube is not completely vulcanized. When the molding mold temperature is too low or the vulcanization time is too short, it will cause the product to cling to the mold and it will not be easy to demould, and it will be more prone to cracking. Other situations will occur, so it is necessary to increase the molding temperature or prolong the curing time during the vulcanization process.
3. The temperature of the Silicone Glass Fiber Tube is too high during molding. If the temperature is too high, the Silicone Glass Fiber Tube will become brittle during molding, and it is easy to break when demoulding, so it is easy to break, so the molding temperature can be lowered appropriately. .
4. If the surface of the Silicone Glass Fiber Tube forming mold is too rough or accumulates dirt, it is not conducive to demoulding, and it will also cause rupture. It only needs to clean or electroplate the mold.
5. Sometimes because the operator's operation method for demoulding is irregular, many problems are more likely to occur, so professional operation training is required for the demoulding operator. The cracking of Silicone Glass Fiber Tube is unavoidable, but we can reduce it through regulations, because the proportion of defective products caused by cracking generally accounts for the majority of silicone rubber products in cracked Silicone Glass Fiber Tube, so it must be ensured during the production process. These aspects need attention.
