透(tou)明塑料由于透(tou)光率要(yao)高，必然要(yao)求塑料制品表面(mian)質量要(yao)求嚴(yan)格(ge)，不(bu)能(neng)有任何斑紋、氣孔、泛白(bai)、霧暈、黑點、變色、光澤不(bu)佳等缺陷(xian)，因(yin)而在(zai)整個(ge)注(zhu)塑過(guo)程對(dui)原(yuan)料、設(she)備(bei)、模具、甚至產品的設(she)計，都要(yao)十...

塑料(liao)(liao)材料(liao)(liao)性能(neng)(neng)的復雜性決(jue)定了(le)注(zhu)射成(cheng)型過程(cheng)的復雜性。而塑料(liao)(liao)材料(liao)(liao)的性能(neng)(neng)又(you)因(yin)品種不(bu)同(tong)(tong)(tong)(tong)、牌號不(bu)同(tong)(tong)(tong)(tong)、生產廠家(jia)不(bu)同(tong)(tong)(tong)(tong)、甚(shen)至批次不(bu)同(tong)(tong)(tong)(tong)而差異較大(da)。不(bu)同(tong)(tong)(tong)(tong)的性能(neng)(neng)參數可(ke)能(neng)(neng)導致完全不(bu)同(tong)(tong)(tong)(tong)的成(cheng)型結果。...

現在(zai)，PET塑料瓶占據了塑料瓶包(bao)裝市場的份額，PET塑料瓶有著很(hen)多的優勢(shi)我(wo)們(men)也多次分析到(dao)。但(dan)是(shi)，今天我(wo)們(men)想要談(tan)論的是(shi)PET塑料瓶包(bao)裝之(zhi)外的其他材質包(bao)裝，它(ta)們(men)正在(zai)被市場所忽略，但(dan)是(shi)...

塑料(liao)的識(shi)別(bie)方法通常采用(yong)外(wai)觀和用(yong)途、密度測試、軟(ruan)化點(dian)(dian)或熔點(dian)(dian)、燃燒試驗、綜合(he)性鑒別(bie)方法鑒別(bie)，下面介(jie)紹常用(yong)的幾種手法工(gong)大家學習：...
