Mavuto ena okhudzana ndi polyethylene ya chlorine:

Chlorinated polyethylene (CPE) ndi polima wokhuta wokhala ndi mawonekedwe oyera a ufa, wopanda poizoni komanso wopanda fungo. Uli ndi kukana bwino nyengo, kukana ozoni, kukana mankhwala, komanso kukana ukalamba, komanso kukana mafuta, kuchedwa kwa moto, komanso mawonekedwe a utoto. Kulimba bwino (kosinthasinthabe pa -30 ℃), kugwirizana bwino ndi zinthu zina za polima, kutentha kwambiri kwa kuwonongeka, kuwonongeka kumapanga HCL, yomwe ingathandize kuchotsa chlorination reaction ya CPE.

Njira yamadzi ya polyethylene yokhala ndi chlorine imagwiritsidwa ntchito kwambiri, yomwe imakhala ndi ndalama zochepa zopangira komanso kuipitsidwa pang'ono. Njira ina ndi njira yoyimitsira, yomwe ndi yokhwima pang'ono. Zapakhomo zimatha kupangidwanso ndikugwiritsidwa ntchito mwachangu, ndipo liwiro louma limakhala lachangu. Nthawi zambiri imagwiritsidwa ntchito m'matanki osungiramo zinthu ndi nyumba zachitsulo kuti ziwongolere chitetezo cha zomangamanga.

Mitundu ya polyethylene yopangidwa ndi chlorine (CPE) ya m'nyumba nthawi zambiri imadziwika ndi manambala monga 135A, 140B, ndi zina zotero. Manambala oyamba 1 ndi 2 akuyimira crystallinity yotsalira (TAC value), 1 ikuyimira TAC value pakati pa 0 ndi 10%, 2 ikuyimira TAC value>10%, manambala achiwiri ndi achitatu akuyimira chlorine, mwachitsanzo, 35 ikuyimira chlorine ya 35%, ndipo nambala yomaliza ndi chilembo cha ABC, chomwe chimagwiritsidwa ntchito kusonyeza kulemera kwa molekyulu ya PE. A ndiye wamkulu kwambiri ndipo C ndiye wamng'ono kwambiri.

Mphamvu ya kulemera kwa mamolekyulu: Chlorinated polyethylene (CPE) ili ndi kulemera kwakukulu kwa mamolekyulu ndi kukhuthala kwakukulu kosungunuka mu zinthu zake zamtundu wa A. Kukhuthala kwake kumafanana bwino ndi PVC ndipo kumakhala ndi zotsatira zabwino kwambiri zofalikira mu PVC, zomwe zimapangitsa kuti pakhale mawonekedwe abwino kwambiri ofalikira. Chifukwa chake, zinthu zamtundu wa A za CPE nthawi zambiri zimasankhidwa ngati chosinthira cha PVC.

Amagwiritsidwa ntchito makamaka pa: waya ndi chingwe (zingwe za mgodi wa malasha, mawaya otchulidwa mu miyezo ya UL ndi VDE), payipi ya hydraulic, payipi ya galimoto, tepi, mbale ya rabara, kusintha mapaipi a PVC, zida zamaginito, kusintha kwa ABS, ndi zina zotero. Makamaka chitukuko cha makampani opanga mawaya ndi zingwe komanso makampani opanga zida zamagalimoto kwapangitsa kuti pakhale kufunikira kwa CPE yochokera ku rabara. CPE yochokera ku rabara ndi rabara yapadera yopangidwa yokhala ndi magwiridwe antchito abwino kwambiri, kukana kutentha kwa mpweya ndi ozoni kukalamba, komanso kuletsa moto kwambiri.

Zinthu zomwe zimakhudza kutentha kwa kutentha kwa CPE

Kapangidwe ka CPE palokha kamagwirizana ndi kuchuluka kwa chlorine komwe kali nako. Ngati kuchuluka kwa chlorine kuli kochuluka, kumakhala kosavuta kuwola;

Zimagwirizana ndi kuyera. Kuchotsa koyenera kwa zoyambitsa, ma catalyst, ma acid, maziko, ndi zina zotero zomwe zimawonjezedwa panthawi ya polymerization, kapena kuyamwa madzi panthawi yosungira ndi mayendedwe, kungachepetse kukhazikika kwa polima. Zinthuzi zingayambitse kuwonongeka kwa ma ion a mamolekyulu, ndipo CPE ili ndi zinthu zochepa kwambiri monga Cl2 ndi HCl, zomwe zimatha kufulumizitsa kuwonongeka kwa utomoni;
