Silicone gutta-percha is a popular daily necessities in recent years. There are many styles and shapes. Many children's gutta-percha products are relatively thick, and the products are not convenient for silicone manufacturers to produce and process. It will lead to unfamiliar products, such as unfamiliarity, etc., and the unfamiliar phenomenon is the majority, and the quality of infant products belongs to the appearance parts, and it is naturally unacceptable for the poor surface, so how to deal with it and what measures should be taken?
First of all, the root of the disease must be found, and the cause and effect must be found in everything. The unfamiliarity of the silicone gum for children often has a certain reason. Our common reasons for unfamiliarity are nothing more than the failure of the vulcanization time of the raw materials to reach the time, or the machine. The temperature is too low or the silicone product manufacturers manually release the mold in advance to improve the efficiency.
Among them, the overall soft and sticky refers to the overall immaturity of the silicone product, and there is no fixed line in any place. It is dead and cannot be repaired. There are several reasons for this. The agent or vulcanizing agent has not been completely dispersed. In addition, the human factors are that the mold release time is too long and the mold release water is sprayed on the surface of the mold to facilitate mold release. At the same time, the mold temperature is lowered and the mold is directly ejected (common reasons).
The internal unfamiliarity is different. In half of the cases, the unfamiliar internal bulges are generated on larger silicone products, such as the root and edge of the handle of the silicone teether for children. The reasons for the unfamiliarity are similar to the overall unfamiliarity. , but this kind of bad also participates in the problem of machine parameters and molds. In addition to the above problems, the mold structure affects the product bulge, such as mold layout, mold core spacing, and the size of the mold template.
On the other hand, partial unripeness is the main factor. This is the case. Partially cooked and partially unripe parts are the most common manifestations. There will be unvulcanized raw rubber on the surface of the silica gel with areas that are not fully cooked. This needs to be summed up. For all the problems, we need to find the reasons, such as whether the raw materials are expired, the pressure of the machine, the number of exhausts of the machine, the structure of the mold, the steel and the operation reasons, and the main reason is that the product is too large, which may lead to the appearance of bulging, and the hardness of the silicone gum is too high. The phenomenon of unfamiliar bulging at Gao needs to be paid more attention!
