Chlorinated Polyethylene CPE Opanga
Mkonzi wa opanga anti-aging agent akudziwitsani lero mawu oyamba okhudza wopanga chlorinated polyethylene cpe. Chlorinated polyethylene (CPE) ndi mankhwala omwe amagwiritsidwa ntchito popanga mankhwala. Anthu ambiri sadziwa za vinyl chloride chloride. Mvetsetsani, chidule cha Chingerezi cha chlorinated polyethylene ndi: CPE kapena cm, chlorinated polyethylene (CPE) ndi zinthu zodzaza polima, mawonekedwe ake ndi ufa woyera, wopanda poizoni komanso wopanda kukoma, wokhala ndi kukana kwanyengo, kukana kwa ozoni, kukana kwa mankhwala ndi kukana kukalamba. , kukana mafuta abwino, kuchedwa kwa lawi ndi mphamvu zoteteza kuwala. Kulimba kwabwino (kusinthasinthabe pa -30 ° C), kugwirizanitsa bwino ndi zipangizo zina za polima, kutentha kwakukulu kwa kuwonongeka, kuwonongeka kwa HCl, HCl ikhoza kuchititsa kuti CPE iwonongeke.
Chlorinated polyethylene (HDPE) ndi zinthu za polima zopangidwa kuchokera ku polyethylene yapamwamba kwambiri (HDPE) ndi chlorination. Malinga ndi mapangidwe ndi ntchito zosiyanasiyana, chlorinated polyethylene imatha kugawidwa mu resin chlorinated polyethylene (CPE) ndi zotanuka chlorinated polyethylene (CM). Kuphatikiza pa ma resins a thermoplastic omwe angagwiritsidwe ntchito okha, amathanso kusakanikirana ndi polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS resin komanso polyurethane (PU). M'makampani a mphira, CPE ingagwiritsidwe ntchito ngati mphira wapamwamba kwambiri, wapamwamba kwambiri, ndipo ingagwiritsidwe ntchito ndi mphira wa ethylene-propylene (EPR), mphira wa butyl (IIR), mphira wa nitrile (NBR), chlorosulfonated polyethylene ( CSM) Gwiritsani ntchito ndi mankhwala ena a rabala.
Katundu wa chlorinated Polyethylene
1) CPE si poizoni, ilibe zitsulo zolemera ndi ma hydrocarboni onunkhira a polycyclic, ndipo imakwaniritsa zofunikira zachitetezo cha chilengedwe.
2) CPE imakhala ndi mafuta abwino kwambiri, makamaka ASTM1 ndi ASTM2 mafuta, ofanana ndi NBR; kukana kwambiri mafuta a ASTM3, abwino kuposa CR komanso ofanana ndi CSM.
3) CPE ili ndi ntchito yodzaza kwambiri ndipo imatha kupangidwa kukhala zinthu zomwe zimakwaniritsa zofunikira zosiyanasiyana. CPE ili ndi machinability kwambiri ndipo imapezeka ku Mooney viscosity (ML1211 +4) kuyambira 50 mpaka 100.
4) CPE ndi mphira wodzaza ndi ukalamba wotsutsa-oxidative, ukalamba wotsutsa-ozone, kukana kwa asidi ndi alkali ndi mankhwala.
5) CPE ili ndi zinthu za chlorine, ili ndi zinthu zabwino kwambiri zoletsa moto, ndipo ili ndi mawonekedwe oletsa kugwa. Antimony-based flame retardant, chlorinated paraffin ndi Al(OH)3 amagwiritsidwa ntchito palimodzi moyenerera kuti apeze zinthu zosagwira moto ndi ntchito yabwino yoletsa moto komanso mtengo wotsika.
