Ndi zotayika zotani zomwe zimayambitsidwa ndi otsika chlorinated polyethylene CPE mu PVC processing

Chlorinated polyethylene (CPE) ndi mankhwala opangidwa ndi klorini opangidwa ndi polyethylene yapamwamba kwambiri (HDPE). Monga chosinthira cha PVC, chlorine ya CPE iyenera kukhala pakati pa 35-38%. Chifukwa cha kukana kwake kwanyengo, kukana kuzizira, kukana moto, kukana mafuta, kukana mphamvu (CPE ndi elastomer), komanso kukhazikika kwamankhwala.

Chlorinated polyethylene (CPE) ndi mankhwala opangidwa ndi klorini opangidwa ndi polyethylene yapamwamba kwambiri (HDPE). Monga chosinthira cha PVC, chlorine ya CPE iyenera kukhala pakati pa 35-38%. Chifukwa cha kukana kwake kwanyengo, kukana kuzizira, kukana kwamoto, kukana kwamafuta, kukana kwamafuta (CPE ndi elastomer), komanso kukhazikika kwamankhwala, komanso kuyanjana kwake ndi PVC, CPE yakhala njira yomwe imagwiritsidwa ntchito kwambiri pagulu la PVC. kukonza.

1. Kusintha kwa Mamolekyulu a HDPE
Chifukwa cha zinthu zosiyanasiyana ndondomeko pa polymerization anachita wa Pe, pali kusiyana mu maselo kasinthidwe ndi katundu wake polima HDPE. The zimatha CPE pambuyo chlorination wa HDPE ndi katundu zosiyanasiyana zimasiyananso. Opanga CPE ayenera kusankha utomoni wa ufa wapadera wa HDPE kuti apange utomoni woyenerera wa CPE.

2. Chlorination zinthu, mwachitsanzo chlorination ndondomeko
CPE, monga PVC processing modifier, kawirikawiri kupangidwa ndi chlorination anachita ntchito amadzimadzi kuyimitsidwa chlorination njira. Zinthu zofunika kwambiri panjira ya chlorination iyi ndi mphamvu yopepuka, mlingo woyambira, kuthamanga kwa zomwe zimachitika, kutentha kwamachitidwe, nthawi yochitira, komanso momwe zinthu zimachitikira. Mfundo ya PE chlorination ndi yosavuta, koma njira ya chlorination ndi yovuta kwambiri.

Chifukwa cha kuchepa kwa ndalama zopangira zida zopangira CPE, zopangira zing'onozing'ono za CPE zamwazika kale ku China. Izi sizimangoyambitsa kuipitsidwa kwa chilengedwe, komanso ndi chimodzi mwa zifukwa zofunika kwambiri za kusakhazikika kwa khalidwe la CPE.

Pakali pano, pali chiwerengero chachikulu cha CPE otsika pa msika. Nthawi zambiri, pali mitundu iwiri ya CPE otsika. Chimodzi ndi chifukwa cha zomera zina zopanga zopanda luso komanso njira zachikale za chlorine. Njira ina ndiyo kusakaniza kuchuluka kwa calcium carbonate kapena talc ufa mu CPE kuti achite nawo mpikisano wopanda chilungamo.
