Zinthu zina zokhudzana ndi chlorinated polyethylene:

Chlorinated polyethylene (CPE) ndi zinthu za polima zodzaza ndi mawonekedwe a ufa woyera, zopanda poizoni komanso zopanda fungo. Ili ndi kukana kwanyengo kwabwino kwambiri, kukana kwa ozoni, kukana kwa mankhwala, komanso kukana kukalamba, komanso kukana mafuta abwino, kutha kwa malawi, komanso kukongoletsa utoto. Good toughness (osinthikabe pa -30 ℃), kugwirizanitsa bwino ndi zipangizo zina za polima, kutentha kwakukulu kwa kuwonongeka, kuwonongeka kumapanga HCL, yomwe imatha kuyambitsa dechlorination reaction ya CPE.

Njira yamadzi ya chlorinated polyethylene imagwiritsidwa ntchito kwambiri, yomwe imakhala ndi ndalama zochepa zopangira komanso kuipitsa bwino. Njira ina ndiyo kuyimitsidwa, yomwe imakhala yokhwima. Zapakhomo zimatha kupititsa patsogolo chitukuko chachiwiri ndikugwiritsa ntchito ndi chitukuko chofulumira, ndipo kuthamanga kwa kuyanika kumathamanga. Amagwiritsidwa ntchito kwambiri m'matanki osungiramo zinthu ndi zitsulo kuti apititse patsogolo chitetezo cha zomangamanga.

Mitundu yapakhomo ya chlorinated polyethylene (CPE) nthawi zambiri imadziwika ndi manambala monga 135A, 140B, ndi zina. Nambala zoyamba 1 ndi 2 zimayimira crystallinity yotsalira (TAC value), 1 imayimira mtengo wa TAC pakati pa 0 ndi 10%, 2 imayimira TAC. mtengo> 10%, nambala yachiwiri ndi yachitatu imayimira chlorine, mwachitsanzo, 35 imayimira 35% ya klorini, ndipo nambala yomaliza ndi chilembo cha ABC, chomwe chimagwiritsidwa ntchito kusonyeza kulemera kwa maselo a PE. A ndiye wamkulu ndipo C ndiye wocheperako.

Mphamvu ya kulemera kwa maselo: Chlorinated polyethylene (CPE) imakhala ndi kulemera kwakukulu kwambiri kwa maselo ndi kusungunuka kwamphamvu kwambiri muzinthu zake zamtundu wa A. Kukhuthala kwake kumafanana ndi PVC yabwino kwambiri ndipo ili ndi zotsatira zabwino kwambiri zobalalika mu PVC, kupanga maukonde abwino ngati mawonekedwe obalalika. Chifukwa chake, zinthu zamtundu wa A CPE nthawi zambiri zimasankhidwa ngati chosinthira cha PVC.

Amagwiritsidwa ntchito makamaka pa: waya ndi chingwe (zingwe za mgodi wa malasha, mawaya otchulidwa mu UL ndi VDE miyezo), payipi ya hydraulic, hose yamagalimoto, tepi, mbale ya mphira, kusintha kwa chitoliro cha PVC, zipangizo zamaginito, kusintha kwa ABS, ndi zina zotero. Makamaka kukula kwamakampani opanga mawaya ndi zingwe komanso makampani opanga zida zamagalimoto kwachititsa kuti pakhale kufunikira kwakugwiritsa ntchito mphira pogwiritsa ntchito CPE. CPE yochokera ku Rubber ndi mphira wapadera wopanga komanso wochita bwino kwambiri, kukana kutentha kwa mpweya ndi ukalamba wa ozoni, komanso kuchedwa kwabwino kwa lawi.

Zomwe zimakhudza kutentha kwa kutentha kwa CPE

Makhalidwe a CPE palokha amagwirizana ndi chlorine yake. Ngati chlorine ili pamwamba, imakhala yosavuta kuwola;

Zimakhudzana ndi chiyero. Kuchotsa kokwanira kwa oyambitsa, zopangira, zidulo, zoyambira, ndi zina zomwe zimawonjezeredwa panthawi ya polymerization, kapena kuyamwa kwa madzi panthawi yosungiramo ndi kunyamula, kungachepetse kukhazikika kwa polima. Zinthuzi zimatha kuyambitsa kuwonongeka kwa ma ion a ma molekyulu, ndipo CPE imakhala ndi zinthu zotsika kwambiri zama cell monga Cl2 ndi HCl, zomwe zimatha kufulumizitsa kuwonongeka kwa utomoni;
