2, 135 ℃ of thermal change type temperature, have poor stability, exist stress be easy to split, low to the breach anti-impact force, wear no resistance, shortcomings such as, viscosity low to the metalwork bounding force is big, mobile difference and influence processing injection moulding.
Acrylonitrile-butadiene-styrene copolymer (ABS) has preferably processing fluidity, advantages such as surface decoration and low price easily, but it also has inflammable, not cold-resistant, frangible and mobile shortcoming such as not good enough.
At present, those skilled in the art mix use with PC, ABS and form compsn, then can reach the effect of learning from other's strong points to offset one's weaknesses, and obtain good comprehensive properties PC/ABS alloy.
Polycarbonate and ABS are material relatively more commonly used, no matter be that PC or ABS all can produce a large amount of defective materials or substandard products, recovery article, the processing for defective material, substandard products or recovery article at present mainly contains following several method:
(1) burning or land-fill method; Because remittance produces obnoxious flavoures such as sulfurous gas in burning process, very easily causes environmental pollution, and takes land-fill method; Because the refractory organics of material also can cause very big harm to environment, present this mode progressively is eliminated;
(2) defective material, substandard products or recovery article are simply reclaimed take out grain and do not carry out any modification, be downgraded to common plastics to use,, fail to make full use of the economic worth of these defective materials though solved problem of environmental pollution.
Therefore, how to reclaim and fully use these defective materials, substandard products or recovery article, it is a problem of benefiting the nation and the people that the back that makes it to regenerate produces new economic benefit.
For cold districts such as the north, so ammeter is owing to have higher requirements to its winter hardiness in outdoor placement, and concerning existing PC/ABS alloy, so cause the winter hardiness of whole PC/ABS relatively poor because of the winter hardiness difference of ABS for a long time.
