Let's talk about the role of carbon black in industrial plastic parts

 

Carbon black is a light, loose and fine black powder with a very large surface area, ranging from 10~3000m2/g. It is a product obtained by incomplete combustion or thermal decomposition of carbon-containing substances under air-deficient conditions. It can be used as a black dye, used to make Chinese ink, ink, paint, plastic particles, etc., and is also used as a reinforcing agent for rubber.

 

Industrial plastic parts because the looseness of carbon black in plastic directly affects the light resistance, color, environmental stress cracking resistance, low temperature brittleness, function, appearance quality, etc. of the product, and in electrical insulation products, carbon black aggregates often cause premature point defects, so whether the carbon black looseness is uniform is the key to the entire production process.

 

 

 

Plastic particles adopt a two-step production process of preparing masterbatch first and then preparing industrial plastic parts plastics. The partner also plans several processes of mixing, plasticating, and extrusion. In addition, relevant process requirements must be formulated during the production process, such as strictly controlling the thickness of the discharged sheet during the plasticizing process, etc.

 

This allows the carbon black to be fully relaxed in the plastic particles of industrial plastic parts, ensuring the required relaxation standard. Plastic particles are a mixture of various types of plasticizers, stabilizers, lubricants, colorants, antioxidants and other compounding agents added to polyvinyl chloride resin.

 

The plastic particles of industrial plastic parts have excellent mechanical properties, good chemical corrosion resistance and weather aging resistance, and are non-flammable. They have certain electrical insulation properties and good processing properties, and are low in cost, so they are currently widely used as insulation and sheath materials for wires and cables. Carbon black, also known as carbon black, is an amorphous carbon.
