　　Rubber Compound SupplierWhat is the production process of rubber compounds?

　　Rubber compound is a very common rubber product, so what is its production process? Let's invite the rubber compound supplier to introduce it to you:

　　1. Process

　　With the rapid development of modern industry, there are various types of rubber products, and the production processes are basically the same. The production process of general solid rubber (raw rubber) products mainly includes: raw material preparation, plasticization, mixing, forming, vulcanization, standing, and inspection.

　　2. Raw Material Preparation

　　The main materials for rubber products include raw rubber, compounding agents, metal materials, and fiber materials. Among them, raw rubber is the base material; compounding agents are auxiliary materials added to improve certain properties of rubber products; metal materials (steel wire, copper wire) and fiber materials (cotton, hemp, wool, various synthetic fibers) are used as skeleton materials for rubber products to enhance mechanical strength and limit product deformation.

　　In order to ensure that raw rubber and compounding agents are mixed evenly, some materials need to be processed, so during the raw material preparation process, the ingredients are accurately weighed according to the formula.

　　3. Plastic Refining

　　Raw rubber is elastic but lacks performance (plasticity) during processing, making it inconvenient to process. To improve its plasticity, raw rubber should be plasticized. This way, the compounding agents can be easily and evenly dispersed in the raw rubber during the mixing process; at the same time, it also helps to improve the permeability (penetration into fiber fabrics) and molding flowability of the rubber material during the calendering process. The process of degradation of long-chain molecules of raw rubber to form plasticity is called plasticization. There are two methods for plasticizing raw rubber: mechanical plasticization and thermal plasticization. Mechanical plasticization refers to the degradation of long-chain rubber molecules from a highly elastic state to a plastic state through mechanical extrusion and friction of the plasticizing machine at low temperatures. Thermal plasticization involves introducing hot compressed air into the raw rubber, where under the action of heat and oxygen, the long-chain molecules are degraded and shortened, thus obtaining plasticity.

　　4. Mixing

　　Mixing is the process of combining the plasticized raw rubber with compounding agents, placing them in a rubber mixing machine, and mechanically mixing to ensure that the compounding agents are completely evenly dispersed in the raw rubber. Mixing is an important step in the production of rubber products. If the mixing is uneven, it affects the performance of the product, and the functions of the rubber and compounding agents cannot be fully realized. The rubber mixture obtained after mixing is called the rubber compound. It is a semi-finished material for manufacturing various rubber products, commonly referred to as rubber material, and is usually sold as a commodity. Buyers can directly process, mold, and vulcanize the rubber compound to produce the desired rubber products.

　　5. Molding

　　In the production process of rubber products, various different sizes and shapes are pre-manufactured using extruders or calenders, a process known as molding.
