Opanga CPE a Chlorinated Polyethylene
Mkonzi wa wopanga mankhwala oletsa kukalamba adzakudziwitsani lero mawu oyamba okhudza wopanga polyethylene cpe wopangidwa ndi chlorinated. Chlorinated polyethylene (CPE) ndi chinthu chomwe chimagwiritsidwa ntchito popanga mankhwala. Anthu ambiri sadziwa za vinyl chloride chloride. Dziwani kuti, chidule cha Chingerezi cha chlorinated polyethylene ndi: CPE kapena cm, chlorinated polyethylene (CPE) ndi chinthu chodzaza ndi polymer, mawonekedwe ake ndi ufa woyera, wopanda poizoni komanso wopanda kukoma, wokhala ndi kukana bwino nyengo, kukana ozone, kukana mankhwala ndi kukana ukalamba, kukana mafuta bwino, kuchedwa kwa moto komanso kuteteza kuwala. Kulimba bwino (kosinthasinthabe pa -30°C), kugwirizana bwino ndi zinthu zina za polymer, kutentha kwambiri kwa kuwonongeka, kuwonongeka kwa HCl, HCl kumatha kuyambitsa kuchotsedwa kwa CPE.
Chlorinated polyethylene (HDPE) ndi chinthu cha polima chopangidwa kuchokera ku polyethylene yapamwamba kwambiri (HDPE) pogwiritsa ntchito chlorination. Malinga ndi kapangidwe ndi ntchito zosiyanasiyana, polyethylene ya chlorinated ingagawidwe kukhala resin chlorinated polyethylene (CPE) ndi elastic chlorinated polyethylene (CM). Kuwonjezera pa ma resin a thermoplastic omwe angagwiritsidwe ntchito okha, amathanso kusakanikirana ndi polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS resin komanso polyurethane (PU). Mu makampani opanga rabara, CPE ingagwiritsidwe ntchito ngati rabara yapadera yapamwamba kwambiri, komanso ingagwiritsidwenso ntchito ndi rabara ya ethylene-propylene (EPR), rabara ya butyl (IIR), rabara ya nitrile (NBR), polyethylene ya chlorosulfonated (CSM). Gwiritsani ntchito ndi mankhwala ena a rabara.
Katundu wa Chlorinated Polyethylene
1) CPE si poizoni, ilibe zitsulo zolemera ndi ma hydrocarbon aromatic polycyclic, ndipo imakwaniritsa zofunikira zonse zoteteza chilengedwe.
2) CPE ili ndi kukana bwino kwa mafuta, makamaka mafuta a ASTM1 ndi ASTM2, ofanana ndi NBR; kukana bwino kwa mafuta a ASTM3, kuposa CR komanso ofanana ndi CSM.
3) CPE imakhala ndi mphamvu zambiri zodzaza ndipo imatha kupangidwa kukhala zinthu zomwe zimakwaniritsa zofunikira zosiyanasiyana zogwirira ntchito. CPE ili ndi makina abwino kwambiri ndipo imapezeka mu Mooney viscosity (ML1211+4) kuyambira 50 mpaka 100.
4) CPE ndi rabara yodzaza ndi ukalamba wabwino kwambiri wotsutsana ndi okosijeni, ukalamba wotsutsana ndi ozoni, kukana asidi ndi alkali komanso mphamvu za mankhwala.
5) CPE ili ndi zinthu za chlorine, ili ndi mphamvu zabwino kwambiri zoletsa moto, komanso ili ndi makhalidwe oletsa kuyaka. Choletsa moto chochokera ku antimony, parafini ya chlorinated ndi Al(OH)3 zimagwiritsidwa ntchito pamodzi moyenerera kuti zipeze zinthu zoletsa moto zomwe zimagwira ntchito bwino komanso zotsika mtengo.
