Talking about the operation time of silicone kitchenware vulcanization,silicone bibs canada

　　Silicone kitchen utensils are a kind of silicone products made of food-grade silica gel as raw material and adding appropriate amount of vulcanizing agent at high temperature. The products are non-toxic, harmless and odor-free. Generally, silicone kitchenware products mainly based on silicone cake molds are large in size and take a long time to form and cure, so the waiting time when processing silicone kitchenware is a very important production link. After the vulcanizing agent is added to the raw rubber, a chemical change occurs, and the vulcanization operation time is calculated from the moment the colloid is added to the vulcanizing agent.

　　In fact, there is no complete boundary between this operation time and the latter vulcanization time. The colloid has already undergone the vulcanization reaction from the moment the vulcanizing agent is added. This operation time means that the 30-minute vulcanization reaction of the product may affect the quality of the finished product. Therefore, the more time saved in the product operation process, the more beneficial to the finished product. This is because the solid silica gel itself is coarse-pored silica gel, which has a very large adsorption capacity and has a strong daughter-in-law performance against moisture and dust in the air. Because the longer the molded silicone takes, the worse it is for the product, and it will also increase a lot of difficulty in the production process.

　　The vulcanization time of silicone kitchenware is divided into raw material vulcanization time and molding vulcanization time. The raw material vulcanization time refers to the reaction time before the raw material is added to the molding machine. The molding time refers to the time during which it is molded by high temperature and high pressure in the vulcanizing machine. When the silicone rubber compound is added to the vulcanizing machine, the vulcanizing agent and silica gel will change greatly at this time, and the atomic space of the raw rubber will change. The structure is also constantly shrinking.
