Kugwiritsa ntchito chlorinated polyethylene (CPE)

Ikuphatikizapo kupanga zokutira, zophimba ndi zinthu zosapsa ndi kutentha, zomwe zimagwiritsidwa ntchito ngati zosinthira za PVC, ABS ndi ma polyolefin ena, kupanga zipangizo zosapsa ndi mankhwala, zikopa zopanga, mapulasitiki a thovu, mafilimu, mbale, zipangizo zomatidwa, zingwe ndi zokutira za waya, ndi zina zotero, ndikukweza kulimba ndi kuchedwa kwa moto kwa zomatira.

Chlorinated polyethylene (CPE) ndi chinthu chopangidwa ndi polima chodzaza ndi mawonekedwe a ufa woyera, chosakhala ndi poizoni komanso chopanda fungo. Chimalimbana bwino ndi nyengo, kukana ozoni, kukana mankhwala, komanso kukalamba, komanso kukana mafuta, kuchedwa kwa moto, komanso kukana utoto. Chimalimba bwino (chimasinthasinthabe pa -30℃), kugwirizana bwino ndi zinthu zina za polima, komanso kutentha kwambiri. Njira yamadzi ya polyethylene yokhala ndi chlorine imagwiritsidwa ntchito kwambiri, yomwe imakhala ndi ndalama zochepa zopangira komanso kuipitsidwa kochepa. Njira ina ndi njira yoyimitsira, yomwe ndi yokhwima pang'ono ndipo imatha kupangidwanso ndikugwiritsidwa ntchito kunyumba. Ili ndi liwiro louma mwachangu. Imagwiritsidwa ntchito kwambiri m'matanki osungiramo zinthu ndi nyumba zachitsulo kuti ikonze chitetezo cha zomangamanga. Mitundu yapakhomo ya polyethylene yokhala ndi chlorine (CPE) nthawi zambiri imadziwika ndi manambala monga 135A, 140B, 239C, ndi zina zotero, pomwe nambala yoyamba 1 ndi 2 ikuyimira kristalo yotsalira (mtengo wa TAC), 1 ikuyimira mtengo wa TAC pakati pa 0-10%, 2 ikuyimira mtengo wa TAC wa 10%, manambala achiwiri ndi achitatu akuyimira kuchuluka kwa chlorine, monga 35 kuyimira kuchuluka kwa chlorine wa 35%, ndipo nambala yomaliza ndi chilembo cha ABC, chomwe chimagwiritsidwa ntchito kusonyeza kulemera kwa molekyulu ya zinthu zopangira PE, pomwe A ndi yayikulu kwambiri ndipo C ndi yaying'ono kwambiri. Chipangizo cha mtundu wa Chlorinated polyethylene (CPE) A chili ndi kulemera kwakukulu kwa mamolekyulu ndi kukhuthala kwakukulu, ndipo kukhuthala kwake kumagwirizana kwambiri ndi PVC. Chili ndi mphamvu yabwino kwambiri yofalikira mu PVC ndipo chimapanga netiweki yoyenera ngati kufalikira. Chifukwa chake, chipangizo cha mtundu wa CPE A nthawi zambiri chimasankhidwa ngati chosinthira cha PVC. Waya ndi chingwe (zingwe za mgodi wa malasha, mawaya ofotokozedwa mu miyezo ya UL ndi VDE), mapayipi a rabara a hydraulic, mapayipi a rabara a magalimoto, tepi, mbale za rabara, kusintha kwa mapaipi a PVC, zida zamaginito, kusintha kwa ABS, ndi zina zotero. Makamaka chitukuko cha makampani opanga mawaya ndi zingwe, komanso makampani opanga zida zamagalimoto, chapangitsa kuti pakhale kufunika kwa polyethylene ya chlorinated yokhala ndi rabara. Polyethylene ya mtundu wa rabara yotchedwa Chlorinated ndi rabara yapadera yopangidwa yokhala ndi magwiridwe antchito abwino kwambiri, kukana kutentha ndi mpweya ndi ozoni kukalamba, komanso kuletsa moto bwino.
