透明塑(su)料(liao)(liao)(liao)由于透光(guang)率要(yao)(yao)高(gao)，必然要(yao)(yao)求塑(su)料(liao)(liao)(liao)制品(pin)表面質(zhi)量要(yao)(yao)求嚴格，不能有任(ren)何(he)斑紋、氣(qi)孔、泛白、霧(wu)暈、黑(hei)點(dian)、變色(se)、光(guang)澤不佳等(deng)缺陷(xian)，因而在(zai)整個(ge)注塑(su)過程對原料(liao)(liao)(liao)、設(she)備、模具、甚至(zhi)產品(pin)的設(she)計，都要(yao)(yao)十...

塑(su)料(liao)(liao)材料(liao)(liao)性(xing)能(neng)(neng)的復雜性(xing)決定了注射成(cheng)型(xing)過(guo)程的復雜性(xing)。而塑(su)料(liao)(liao)材料(liao)(liao)的性(xing)能(neng)(neng)又因品種(zhong)不(bu)同(tong)(tong)(tong)、牌號(hao)不(bu)同(tong)(tong)(tong)、生產(chan)廠家不(bu)同(tong)(tong)(tong)、甚至(zhi)批次不(bu)同(tong)(tong)(tong)而差異較大。不(bu)同(tong)(tong)(tong)的性(xing)能(neng)(neng)參數可(ke)能(neng)(neng)導致完全不(bu)同(tong)(tong)(tong)的成(cheng)型(xing)結果(guo)。...

現在(zai)，PET塑(su)(su)料(liao)瓶(ping)(ping)占據了塑(su)(su)料(liao)瓶(ping)(ping)包(bao)裝市場(chang)的(de)份額，PET塑(su)(su)料(liao)瓶(ping)(ping)有著很多的(de)優勢我們(men)也多次分(fen)析到。但(dan)是(shi)，今天我們(men)想要談論的(de)是(shi)PET塑(su)(su)料(liao)瓶(ping)(ping)包(bao)裝之外(wai)的(de)其(qi)他材質包(bao)裝，它們(men)正在(zai)被(bei)市場(chang)所(suo)忽略，但(dan)是(shi)...

塑料的識別方法通常(chang)采用外觀和用途、密度測試、軟化(hua)點或熔(rong)點、燃燒(shao)試驗(yan)、綜合性(xing)鑒(jian)別方法鑒(jian)別，下面介紹常(chang)用的幾種(zhong)手法工大家學習：...
