Chlorinated polyethylene (CPE) o se mea polymer tumu, foliga o le paʻepaʻe paʻepaʻe, e le oona ma le tofo, ma le lelei o le tau tetee, ozone tetee, kemikolo tetee ma le matua tetee, ma le lelei o le suauu tetee, mumu mumu ma le valivali meatotino.Malosi lelei (fa'alelei pea i le -30 ℃), e lelei le feso'ota'iga ma isi mea polymer, maualuga le vevela, fa'aleagaina o le HCl, HCl e mafai ona fa'afefeteina le fa'afefeteina o le CPE.
Igoa Aloaia: Chlorinated Polyethylene, Fa'apu'upu'u: CPE, Chlorinated polyethylene o se mea polymer saunia mai le polyethylene maualuga (HDPE) e ala i le chlorination substitution reaction.E tusa ai ma le fausaga eseese ma le faʻaaogaina, e mafai ona vaevaeina le polyethylene chlorinated i le resin chlorinated polyethylene (CPE) ma le elastic type chlorinated polyethylene (CM) lua vaega.I le faaopoopo atu i le faʻaaogaina na o ia, e mafai foi ona faʻafefiloi resini vevela ma le polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS ma e oʻo lava i le polyurethane (PU).I totonu o le alamanuia pa'u, e mafai ona fa'aogaina le CPE e avea o se pa'u fa'apitoa maualuga, maualuga, ma e mafai fo'i ona fa'afefiloi ma le ethylene propylene rubber (EPR), butyl rubber (IIR), nitrile butadiene rubber (NBR), chlorosulfonated polyethylene ( CSM) ma isi pa'u.
Uiga CPE
1, CPE o se ituaiga o paʻu tumu, e sili ona lelei le vevela okesene le matua, osone matua, acid ma alkali tetee, meatotino vailaau.
2, o le suauʻu tetee o le CPE e lautele, ma o le tetee i le ASTM 1 suauu ma ASTM 2 suauu e sili ona lelei, lea e tutusa ma le NBR;E sili atu le tetee ile ASTM 3 suauʻu, sili atu nai lo CR, ma faʻatusatusa ile CSM.
3, CPE o loʻo i ai le chlorine, e sili ona lelei le faʻaogaina o le afi, ma o loʻo i ai uiga faʻafefete faʻafefe.O mea e fa'asa'o ai le mu ma le lelei o le fa'atinoga o le mu ma le tau maualalo e mafai ona maua e ala i le fa'atatauga talafeagai o le antimony mumu mumu, chlorinated paraffin ma Al(OH)3.
4. CPE e le oona, e le aofia ai metala mamafa ma PAHs, ma ausia atoatoa manaoga tau siosiomaga.
5, CPE o loʻo i ai le maualuga o le faʻatumuina o faʻatinoga, e mafai ona saunia e faʻafetaui le tele o manaʻoga faʻatinoga eseese o le oloa.CPE o loʻo lelei le faʻatinoina o gaioiga ma Mooney viscosity o loʻo maua i le tele o togi i le va o le 50-100.
