Chlorinated polyethylene (CPE) ndi zinthu zodzaza ndi polima, mawonekedwe a ufa woyera, wopanda poizoni komanso wopanda kukoma, wokhala ndi kukana kwanyengo, kukana kwa ozoni, kukana mankhwala ndi kukalamba kukana, kukana mafuta abwino, kuletsa moto komanso kukongoletsa utoto.Kulimba kwabwino (kusinthikabe pa -30 ℃), kumagwirizana bwino ndi zida zina za polima, kutentha kwapang'onopang'ono, kuwonongeka kwa HCl, HCl imatha kupangitsa kuti CPE iwonongeke.
Dzina Lovomerezeka: Chlorinated Polyethylene, Chidule: CPE, Chlorinated polyethylene ndi polima zakuthupi zokonzedwa kuchokera ku polyethylene yapamwamba (HDPE) ndi chlorination m'malo momwe zimachitikira.Malinga ndi kapangidwe ndi ntchito zosiyanasiyana, chlorinated polyethylene akhoza kugawidwa mu utomoni chlorinated polyethylene (CPE) ndi zotanuka mtundu chlorinated polyethylene (CM) magulu awiri.Kuphatikiza pa kugwiritsidwa ntchito kokha, ma resins a thermoplastic amathanso kusakanikirana ndi polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS komanso polyurethane (PU).M'makampani a mphira, CPE ingagwiritsidwe ntchito ngati mphira wapamwamba kwambiri, wapamwamba kwambiri, ndipo imatha kuphatikizidwa ndi mphira wa ethylene propylene (EPR), mphira wa butyl (IIR), mphira wa nitrile butadiene (NBR), chlorosulfonated polyethylene ( CSM) ndi ma rubber ena.
Mtengo wa CPE
1, CPE ndi mtundu wa mphira wodzaza, uli ndi ukalamba wabwino kwambiri wa kukana kwa okosijeni, ukalamba wa ozoni, kukana kwa asidi ndi alkali, katundu wamankhwala.
2, kukana kwamafuta kwa CPE ndikokwanira, komanso kukana kwa ASTM 1 mafuta ndi ASTM 2 mafuta ndizabwino kwambiri, zomwe ndizofanana ndi NBR;Kukana kwabwino kwa ASTM 3 mafuta, kuposa CR, komanso kufananiza ndi CSM.
3, CPE ili ndi chlorine, imakhala ndi ntchito yabwino kwambiri yoletsa moto, ndipo imakhala ndi mawonekedwe odana ndi kudontha.Zotsalira zalawi zokhala ndi ntchito yabwino yoletsa malawi komanso mtengo wotsika zitha kupezedwa ndi gawo loyenera la antimony flame retardant, chlorinated paraffin ndi Al(OH)3.
4. CPE ndi yopanda poizoni, ilibe zitsulo zolemera ndi PAHs, ndipo imakwaniritsa zofunikira za chilengedwe.
5, CPE ili ndi ntchito yodzaza kwambiri, imatha kukonzekera kuti ikwaniritse zofunikira zosiyanasiyana za chinthucho.CPE ali bwino processing ntchito ndi kukhuthala kwa Mooney likupezeka zosiyanasiyana sukulu pakati 50-100.
