style="text-indent:25px">PP塑料的微生物降解：塑料是一種以聚合物為主要成分的材料，可分為天然塑料和合成塑料兩類(lèi)。天然塑料是由天然的或微生物分泌的大分子物質(zhì)組成的一類(lèi)塑料，廣東PP塑料堵頭定做價(jià)格，如多羥基丁酸 (PHB)。這類(lèi)塑料多具有可生物降解的特性，因而是一類(lèi)環(huán)境友好型材料，但這類(lèi)天然塑料在現(xiàn)實(shí)應(yīng)用中*占很小的一部分。隨著塑料產(chǎn)業(yè)的發(fā)展及塑料制品的較廣使用和消耗，越來(lái)越多的廢舊石油基塑料制品進(jìn)入到了環(huán)境中。合成塑料作為一種非天然的石油基塑料，由于其分子量過(guò)大且疏水而難以通過(guò)生物膜，因此很難被微生物所利用；同時(shí)，塑料單體間往往通過(guò) C-C 鍵等非常強(qiáng)的共價(jià)鍵結(jié)合，因此要破壞這種高分子聚合鏈非常困難。因此這些高分子聚合物進(jìn)入環(huán)境后很難被微生物降解，帶來(lái)了嚴(yán)重的環(huán)境污染，“白色污染”已經(jīng)成為一個(gè)全球性問(wèn)題。常規(guī)處理塑料廢棄物的物理和化學(xué)的方法有具有成本高、副產(chǎn)品多和產(chǎn)生二次污染的局限性。PP的化學(xué)穩(wěn)定性?xún)?yōu)異，廣東PP塑料堵頭定做價(jià)格，對(duì)大多數(shù)酸、堿，廣東PP塑料堵頭定做價(jià)格、鹽、氧化劑都顯惰性。廣東PP塑料堵頭定做價(jià)格</p><div

polypropylene)是聚丙烯與玻璃纖維或有機(jī)纖維、石棉、或無(wú)機(jī)填料(滑石粉、碳酸鈣)的混合物。通常采用加入玻璃纖維、粉體添加劑或彈性體的方法對(duì)PP進(jìn)行改性。加入30%的玻璃纖維可以使收縮率降到0.7%。均聚物型和共聚物型的PP材料都具有優(yōu)良的抗吸濕性、抗酸堿腐蝕性、抗溶解性。然而，它對(duì)芳香烴（如苯）溶劑、氯化烴（四氯化碳）溶劑等沒(méi)有抵抗力。PP也不象PE那樣在高溫下仍具有抗氧化性。一般工業(yè)用的玻璃纖維增強(qiáng)聚丙烯中含10～30%的纖維。由于含有玻璃纖維而具有良好的耐熱性和尺寸穩(wěn)定性。增強(qiáng)聚丙烯主要用于制造各種機(jī)械零件，主要包括汽車(chē)風(fēng)扇、空調(diào)風(fēng)扇、凈水器濾瓶，在電器行業(yè)可用于各類(lèi)家電外觀件替代ABS、HIPS,較廣用于冰箱頂蓋、空調(diào)底座、足浴器等。</p><p
