1.山東注塑加工 http://www.shopcoachsale.com/的原料混有其它雜質或摻雜了不適當的或過量的溶劑或其它添加劑時。In Shandong, the raw materials of the injection molding process are mixed with other impurities or adulterated with inappropriate or excessive solvents or other additives.

2.有些塑料如ABS等,在受潮狀況下加熱會與水汽發生催化裂化反應,使山東注塑加工制件發生大的應變。Some plastics, such as ABS and so on, under the condition of damp heat and water vapor catalytic cracking reaction, so that the injection molding parts of Shandong.

3.塑料再生次數太多或再生料含量太高,或在山東注塑加工機筒內加熱時間太長,都會促使制件脆裂。Too many times of recycled plastic or recycled material content is too high, or in Shandong injection molding machine barrel heating time is too long, will promote the brittle crack.

4.塑料本身質量不佳,例如分子量分布大,含有剛性分子鏈等不均勻結構的成分占有量過大;或受其它塑料摻雜污染、不良添加劑污染、灰塵雜質污染等是造成山東注塑加工發脆的原因。The plastic is of poor quality, such as large molecular weight distribution, with rigid molecular chain structure of the components such as uneven amount is too large; or doping by other plastic pollution, poor additive pollution, dust impurities pollution is the cause of Shandong injection molding crisp.
