With the increasing use of rubber compounds, rubber compounds are becoming more and more well-known. There are not many people who have invested in the production of rubber compounds. This involves the production of rubber compounds. Jinhaotai Machinery has many years of experience in the production of rubber mixing equipment. Now we will inform you about the production process of rubber mixing.
The basic preparation process of compounded silicone rubber The compounded silicone rubber can be generally prepared on a general-purpose rubber mixer, and the large-scale production is carried out in a kneader or a closed mixing machine.
1. First, if you want to put the silicone rubber into the production, you must add the vulcanizing agent before you can vulcanize it on the vacuum vulcanizer. There are two kinds of vulcanization methods: 50 kg or less of compounded silicone rubber and sulfur can be added to the mill to a certain proportion of the vulcanizing agent, and the mixture is smooth until the surface is smooth; 50 kg or more of the kneaded silicone rubber must be added to the kneading machine. The vulcanizing agent is added until the kneading is uniform and then kneaded on the mill roll until the surface is smooth.
2. The vulcanized silicone rubber with the vulcanizing agent can be directly put into production. Firstly, the oil paper for packaging and mixing the silicone rubber should be opened, and the raw material of the kneaded silicone rubber should be cut into pieces by a blade and then put into a vacuum vulcanizer. Into the rubber compound, it is necessary to weigh the weight on the electronic scale, and then place the rubber evenly on the mold. The amount of compounded silicone rubber compound needs to be based on the weight and size of the silicone product itself.
3. Finally, the vulcanization temperature and time should be adjusted. Generally, the vulcanization temperature of the silica gel product is between 170 ° C and 180 ° C, and the vulcanizing agent time is 60 s - 180 s. The specific quality is based on the product quality. After repeated adjustment tests and selection of the best vulcanization temperature and time, a brand new silicone product was officially released.
