Changshu da plastic products factory is introduced principle of ABS plastic different profile production smoothly

There are three kinds of ABS plastic special-shaped material composition, respectively is: acrylonitrile ( Acrylonitrile） , 1, 3 - Butadiene ( Butadiene） (styrene, 苯乙烯) Three kinds of monomers. Butadiene acrylonitrile accounted for 15% ~ 35%, 5% ~ 30%, 40% ~ 60% styrene. And chemical taste a bit is, the same material composition, the proportion of different can produce different effects. ABS plastic different profile with high impact, high hardness, not bibulous, corrosion resistance, insulation and other characteristics by people chase after hold in both hands! ABS plastic special-shaped material is a kind of extrusion products made of extrusion molding process, actually not difficult ABS plastic in extrusion principle, changshu well below introduces the general principle of extrusion production of plastic products factory!



a screw rotating in the cylinder and the ABS extruding plastic push forward. Screw is actually a inclined plane or slope, wrapped around the center layer. Its purpose is to increase the pressure in order to overcome the resistance of the larger. In terms of an extruder, there are three kinds of resistance to overcome: solid particles ( Feed) Of wall friction and screw rotation (several times before Feed zone) The friction between them. The adhesive force of the melt on the wall; The melt is pushing forward its internal logistics resistance.
