I. Basic Knowledge Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can undergo significant deformation under a small external force. After the external force is removed, it can return to its original state. Rubber is a completely amorphous polymer. Its glass transition temperature (Tg) is low and its molecular weight is often very large, exceeding several hundred thousand. Rubber is divided into two types: natural rubber and synthetic rubber. Natural rubber is processed by extracting rubber from plants such as rubber trees and rubber grass. Synthetic rubber is obtained through polymerization reactions of various monomers. Rubber products are widely used in various aspects of industry or daily life. II. Production, Supply and Sales Situation Production situation Global production: According to data...

Based on the analysis of the vulcanization process, it can be divided into four stages, namely the scorching stage, the hot vulcanization stage, the flat vulcanization stage and the over-vulcanization stage. An ideal rubber vulcanization curve should meet the following conditions: (1) The vulcanization induction period should be long enough to fully ensure the safety of production and processing; (2) The vulcanization speed should be fast to improve production efficiency and reduce energy consumption. (3) The vulcanization flattening period should be long. Performance Changes of Rubber during vulcanization (1) Physical Property Changes During the vulcanization process, the physical and mechanical properties of rubber change significantly. Therefore, in the production process, the degree of vulcanization is often measured by the changes in physical properties. The physical p...

1.Basic process flow With the rapid development of modern industry, especially the chemical industry, there are various types of rubber products, but their production processes are basically the same. The production process of products made from general solid rubber (raw rubber) mainly includes: Raw material preparation → plasticizing → mixing → molding → vulcanization → rest → inspection 2.Preparation of raw materials The main materials of rubber products are raw rubber, compounding agents, fiber materials and metal materials. Among them, raw rubber is the basic material; Compounding agents are auxiliary materials added to improve certain properties of rubber products. Fiber materials (cotton, linen, wool and various artificial and synthetic fibers) and metal materials (steel wire, copper wire) are used as reinforcing materials for rubber products ...

Rubber hose is a steel wire braided rubber hose. The rubber hose is composed of an inner rubber layer, a steel wire braided layer and an outer rubber layer. It is suitable for conveying hydraulic fluids, such as alcohol, fuel oil, lubricating oil, emulsion, etc. Compared with civilian hoses, industrial operation environments are more complex and harsh, and the requirements for conveying pipes by equipment are also more stringent. Therefore, industrial hoses have strict norms and standards from design, material selection to production, transportation and even final storage. The size range of industrial hoses is wider, the pressure and temperature range is extensive, and the chemical resistance is higher. The application fields of industrial hoses cover various industrial production, manufacturing and circulation sectors. They are widely used in industries such as petroleum, chemic...
