Did you know that rubber hoses are everywhere in our daily life and industrial production? It has a delicate structure and is generally composed of an inner rubber layer, a steel wire braided layer and an outer rubber layer. ​From daily irrigation and car washing to the industrial transportation of hydraulic fluids, alcohols, fuel oil and lubricating oil, it can be found everywhere. It is even more indispensable in industries such as petrochemicals, shipbuilding, and food and beverage. For example, water delivery hoses are used for irrigation and fire protection. Hot water and steam hoses are used for equipment cooling and food processing. Beverage and food hoses are used to transport milk, juice, etc., and must meet strict food-grade standards. ​The industrial working environment is complex and has high requirements for it. There are standards for dimensions, pressure, chemic...

Deep in the Amazon rainforest, the Indians once discovered a kind of "weeping tree" - as long as the bark was cut, the milky white SAP would drip like tears. This magical liquid is precisely the source of natural rubber. In 1876, 22 rubber saplings crossed the ocean from Brazil to Southeast Asia. Under the hard work and sweat of Chinese laborers, this land now contributes 90% of the world's natural rubber.The transformation of rubber began in 1844 when the American Goodyear invented vulcanization technology, which turned rubber from the "strange tree SAP" that became sticky when heated into a tough and durable industrial material. Today, from car tires to space shuttle seals, from medical gloves to smart wearable devices, more than 70,000 kinds of products rely on this elastic material. Chinese scientists have further broken through the technological blockade and dev...

Rubber is a kind of high-elastic polymer material and plays an indispensable role in human life. In the early 19th century, people extracted natural rubber from Brazilian rubber trees, initiating the history of rubber applications. With the development of industry, synthetic rubber emerged, making up for the deficiencies of natural rubber in terms of output and performance. ​There are various types of rubber. Natural rubber has excellent elasticity and insulation properties and is widely used in the manufacture of tires, seals, etc. Synthetic rubber can adjust its performance according to demand. For instance, nitrile rubber is oil-resistant and silicone rubber is heat-resistant, making it highly effective in fields such as aerospace and medical care. ​From car tires to medical gloves, from shock-absorbing parts to sports goods, rubber, with its properties of wear resistance, ...

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...
