Thermoplastics for welding fume processing equipment
are softened when heated, easily melted, and become transparent when melted. They can often be pulled out of the melt, which is usually easy to heat-seal. The thermosetting plastic is heated until the material is chemically decomposed, and its original hardness is not softened, and its size is relatively stable. When the elastomer is heated, it does not flow until the chemical decomposition temperature, and the material is decomposed and carbonized until the decomposition temperature.
So what are the main sources of pollution from welding construction? There are mainly the following: waste smoke emitted by traction equipment; waste smoke emitted by the main generator of the welding smoke treatment equipment
generated during welding of the rails; smoke generated by small generators; smoke generated during rust removal and grinding and many more. In the industrial production process, construction workers are required to wear other protective measures such as masks, mainly to prevent pollution from waste smoke and exhaust gas. Therefore, corresponding welding fume purification equipment will be equipped in the industrial production workshop to purify environmental pollution.
