Assign the special physical chemistry effects such as fire-retardant plastic products, conductive, thermally conductive, magnetic conduction, antistatic, antibacterial.Although the technology road
Position of mainstream is occupied in current modifying plastics manufacture field, however in the technology implementation process, all substrates resin with change
Property additive all have to pass through twin-screw extrusion and injection moulding melt-processed thermal history twice, polymer molecular chain and its correlation
Modified additive will appear different degrees of degradation, and the Long Service Life for causing plastic products final shortens.This technology road
Line also increases process-cycle and the energy consumption of modified plastics, runs counter to the basic concept of the current sustainable industrial development of green.This
Outside, for the modified additive of different shape and different materials matter there may be the greatest differences of process unit and processing technology,
Such as high temperature high shear effect can be played using twin-screw extrusion machining, the modified performances such as activeness and quietness are performed into maximum limit
Degree；And utilize the low temperature of mixer and mediate effect for a long time, can will not heatproof auxiliary agent, low melting point auxiliary agent, low bulk density it is difficult
