silicone resins usually require attention to safety issues during processing, so what should be paid attention to in the safety aspects of silicone resin processing? Next, silicone resin manufacturers will introduce you to this knowledge, and follow this article to understand the relevant knowledge.
1. Toxic chemicals such as silicone resin and hardener should be kept together.
2. When preparing the compound with silicone resin, it should be carried out in a well-ventilated place, and the person should stir at the upwind place. Construction workers avoid continuous work, and generally change work once every 2 to 3 days.
3. Plastic gloves or medical gloves should be worn during the construction of silicone resin. Wash hands with alcohol and soap after work. When the skin comes into contact with the curing agent, it should be immediately rinsed with water or wiped with alcohol and then washed with water. It is forbidden to wash hands with acetone, toluene or banana water.
4. No smoking or eating during working hours. If you find dizziness or fatigue, you should leave your work and rest in a ventilated place.
Silicone main products and uses
Organosilicon monomer mainly refers to organochlorosilane and other monomers that synthesize organosilicon polymers, such as methylchlorosilane, phenylchlorosilane, vinylchlorosilane, ethyltrichlorosilane, propyltrichlorosilane, vinyl Trichlorosilane, γ-chloropropyltrichlorosilane, fluorosilicone monomer, etc.
Despite the large variety of silicones, the starting materials for production are limited to a few organosilicon monomers, the largest of which is dimethyldichlorosilane, accounting for more than 90% of the total monomer usage, followed by benzene Chlorosilane. In addition, trimethyl chlorosilane, ethyl and propyl chlorosilane, vinyl chlorosilane, etc., are also indispensable raw materials for the production of certain varieties. The key to the development of the silicone industry is the development of monomer technology. The production level of monomers directly reflects the development level of the silicone industry.
Organochlorosilanes (methylchlorosilane, phenylchlorosilane, vinylchlorosilane) are the foundation of the entire silicone industry, and methylchlorosilane is the backbone of the silicone industry. Most of the silicone polymers are first made from dimethyldichlorosilane as the raw material to obtain polydimethylsiloxane, and then based on polydimethylsiloxane, other groups such as phenyl, Manufactured from vinyl, chlorophenyl, fluoroalkyl, etc. Methylchlorosilane production process is long and technically difficult. It is a technology-intensive and capital-intensive industry. Therefore, all major foreign companies are implementing large-scale centralized construction and production of basic products, and post-processed products are scattered according to uses and market conditions. .
