Compound Rubber SupplierIn the production process of compound rubber, rubber is generally suitable for molding processes, and a small amount can be formulated into general-purpose compound machines. Large-scale production is carried out on kneaders or closed mixing equipment. The mixing of silicone rubber in a kneader can improve production efficiency and enhance the working environment, using the basic process. After removing water and other volatiles, silica is added to promote the dispersion of silicone rubber adhesives, and after adding silica and structural control agents, heat treatment is carried out at 150 to 1180 for 6 hours; then, further kneading is done in a two-roll mill, and modifiers are added; finally, filtering is done to remove impurities in the rubber compound. The basic formula and mixing of silicone rubber in the compound rubber supplier's silicone rubber mixing process can be formulated in a general rubber kneader, and large-scale production is performed in a kneader or mixing device.
1. First, to develop the production of mixed silicone rubber, it must go through the addition of curing agents to use curing technology for molding on a vacuum curing machine. There are two methods of vulcanization: for mixed silicone rubber under 50 kg, the curing agent can be added in a certain time ratio to the open mill until a smooth surface is formed; for mixed silicone rubber over 50 kg, the curing agent must be added in a kneader until the mixing temperature is uniform, and then mixed on the open mill roller until the surface is relatively smooth.
2.Compound Rubber SupplierTo add the mixed silicone rubber curing agent, it can be directly put into production. First, open the packaging of the silicone rubber kneading oil-proof paper, cut the silicone rubber mixed raw materials with a blade, and then place them in the vacuum-generated curing agent. The weight of the mixed silicone rubber material must be weighed on a scale, and then evenly displayed in the rubber mold. The mixing is based on the required amount of silicone rubber product itself as the standard size and weight used for the silicone rubber material.
3. Finally, adjust the curing reaction temperature and time. Generally, the curing temperature for silicone products is between 170°C-180°C, and the curing agent time is 60s-180s, specifically based on the impact of the quality of the enterprise's product service as the standard. After continuous structural adjustments and research experiments, after selecting the best curing temperature and time, a brand new silicone product from the compound rubber supplier is officially produced.
