The manufacturing method
of special rubber
1. Introduction

special rubber has an important position in the field of chemical production raw materials. Because of its unique physical and chemical properties, it is widely used in aviation, automobile, electronics, medical and other fields. This paper will introduce the manufacturing method of special rubber in detail, including raw material preparation, mixing, vulcanization, molding and other steps, in order to provide reference for the production of special rubber.

2. raw material preparation

1. Rubber raw rubber: Choose high-quality rubber raw rubber as raw material to ensure that it has low impurity content and high Mooney viscosity.
2. filler: according to the performance requirements of special rubber, select the appropriate filler, such as carbon black, white carbon black and so on.
3. Additives: Add the right amount of additives, such as antioxidants, accelerators, vulcanizing agents, etc., to improve the performance of special rubber.

3. mixing

raw rubber, fillers and additives are put into an internal mixer or an open mixer according to a certain proportion for mixing. During the mixing process, the temperature and time should be controlled to ensure that the compound is evenly mixed, while avoiding excessive shear and oxidation.

4. vulcanization

The mixed compound is put into the mold and vulcanized in the vulcanizer. During the vulcanization process, the temperature, pressure and time need to be controlled to make the rubber molecules cross-link to form a three-dimensional network structure, so as to obtain the required physical and chemical properties.

5. molding

vulcanization is completed, the mold is opened, and the molded special rubber products are taken out. Care was taken to avoid damage to the product during removal.

6. post-treatment

post-treatment of special rubber products as needed, such as polishing, painting, etc., to improve their appearance quality and durability.

7. quality control

In the production process, it is necessary to carry out strict quality inspection on raw materials, semi-finished products and finished products to ensure that the product quality meets the relevant standards and customer requirements. At the same time, regular maintenance and maintenance of production equipment is carried out to ensure the normal operation of the equipment and reduce the failure rate.

8. environmental protection and safety production

in the production process, should pay attention to environmental protection and safety production. Take effective measures to reduce energy consumption and waste emissions, improve resource utilization. Strengthen staff safety training to ensure that the production process complies with relevant regulations and standards.

9. technology innovation and R & D

In order to improve the performance of special rubber and reduce costs, enterprises should pay attention to technological innovation and R & D. Strengthen cooperation with scientific research institutions and universities, introduce advanced production technology and equipment, and improve product competitiveness.

10. market development and sales

to strengthen market development and sales, broaden sales channels, and increase the market share of special rubber. By establishing stable cooperative relations with downstream enterprises, we can realize the docking of production and marketing and improve the added value of products.

XI. Summary and Prospect

special rubber has a wide range of application prospects in the field of chemical production raw materials, and its manufacturing methods involve raw material preparation, mixing, vulcanization, molding and other links. Through strict quality control, environmental protection and safety production, technological innovation and research and development, as well as market expansion and sales efforts, we can further improve the performance and market competitiveness of special rubber. Looking to the future, with the continuous progress of science and technology and the expansion of application fields, special rubber will usher in a broader space for development.
