Sulfur powder is a chemical with a special pungent odor. As a very important chemical industry raw material, it plays a pivotal role in industrial production. But some objects in our daily life will change the original properties of objects because of their existence. The connection between the rubber-specific sulfur powder made by the fine processing of industrial sulfur powder and rubber can be said to be close.
Cars have become an indispensable part of people’s daily life, and rubber tires are widely used in the automotive industry. Do you know why that is? In natural rubber, the combination of sulfur powder can prevent vulcanization from returning to its original state, improve heat resistance, reduce heat generation, anti-aging, and improve the adhesion between rubber and cord and the modulus of vulcanized rubber. It can be used in tire shoulder rubber, buffer layer and other rubbers, which can solve the problem of oblique emptying of tire shoulders, and can also be used in large-sized and thick products of natural rubber and various rubber miscellaneous products. Vulcanization refers to the chemical change process in which the linear macromolecular chains of rubber form a three-dimensional network structure through chemical cross-linking. After curing, the physical and other properties of the rubber change radically. The whole vulcanization process can be divided into four stages: vulcanization induction, pre-vulcanization, positive vulcanization and overvulcanization (vulcanization returns to the original state of natural rubber).
Thanks to the use of sulphur powder, the action of natural rubber is significantly improved. Wheels made of rubber absorb shocks and keep car parts from damage. At the same time, it is very durable and low cost, so it is widely used in the rubber industry, called rubber sulfur powder.
The wonderful chemical reaction between rubber-specific sulfur powder and rubber brings the convenience of tires to our life and contributes to our better life.
