Nolosheenna, CPE iyo PVC aad iyo aad ayaa loo isticmaalaa.Polyethylene Chlorinated waa maado polymer ah oo buuxa oo leh muuqaal budo cad ah, aan sun ahayn oo aan dhadhan lahayn, waxayna leedahay iska caabin cimilo oo aad u wanaagsan, iska caabin ozone, caabbinta kiimikada iyo iska caabinta gabowga.Waxqabadka, oo leh caabbinta saliidda wanaagsan, dib u dhaca ololka iyo sifooyinka midabaynta.Adayg wanaagsan (wali waa dabacsan yahay -30°C), waafaqid wanaagsan oo ay la socdaan agabka kale ee polymer, iyo heerkul sare oo burbursan.Polyethylene Chlorinated waa walxo polymer ah oo laga sameeyay polyetylen cufnaanta sare leh (HDPE) iyada oo loo marayo falcelinta beddelka koloriinta.Sida laga soo xigtay qaab-dhismeedka iyo isticmaalka kala duwan, polyetylen koloriin ah ayaa loo qaybin karaa laba qaybood: Nooca resin-ka koloriineed polyetylen (CPE) iyo nooca elastomer-ka koloriinated polyetylen (CM).Marka laga reebo in la isticmaalo kaligaa, resins thermoplastic sidoo kale waxaa lagu dhex dari karaa polyvinyl chloride (PVC), polyetylen (PE), polypropylene (PP), polystyrene (PS), ABS iyo xitaa polyurethane (PU).Warshadaha caagga ah, CPE waxaa loo isticmaali karaa sidii wax-qabad heersare ah, caag gaar ah oo tayo sare leh, waxaana sidoo kale loo isticmaali karaa caag ethylene-propylene (EPR), rubber butyl (IIR), rubber nitrile (NBR), chlorosulfonated polyethylene CSM), iwm. Isku darka caag kale ayaa la isticmaalaa.
1960-meeyadii, shirkadda Jarmalka ee Hoechst waxay markii ugu horreysay si guul leh u horumarisay oo ay xaqiiqsatay wax soo saarka warshadaha.Dalkaygu wuxuu bilaabay inuu soo saaro polyetylen koloriin leh dabayaaqadii 1970-yadii."Hakinta Wajiga Aqueous ee Farsamada CPE" ayaa markii ugu horreysay si guul leh u soo saaray Machadka Cilmi-baarista Kiimikada Anhui, iyo qalabka wax soo saarka ee 500-1000t / a oo leh miisaan kala duwan ayaa laga dhisay Wuhu, Anhui, Taicang, Jiangsu, iyo Weifang, Shandong .
Iska caabbinta saliidda ee CPE waa celcelis ahaan, oo ay ka mid yihiin caabbinta ASTM No. 1 saliid iyo ASTM No. 2 waa mid aad u fiican, taas oo u dhiganta NBR;caabbinta saliidda ASTM No. 3 aad bay u fiican tahay, way ka fiican tahay CR, taas oo u dhiganta CSM.
CPE waxa ku jira koloriin, taas oo leh sifooyin dib-u-dhigista ololka oo aad u wanaagsan oo leh sifooyinka gubashada iyo ka-hortagga dhibicda.Waxaa lagu dari karaa dabcelis ku salaysan antimony, paraffin koloriin leh, iyo Al(OH)3 iyadoo la eegayo saamiga ku haboon si loo helo walxo ololka celisa oo leh waxqabad aad u wanaagsan oo dab-demis ah iyo qiimo jaban.
CPE ma aha sun, kuma jiraan biro culus iyo PAHS, waxayna si buuxda u buuxisay shuruudaha ilaalinta deegaanka.
CPE waxay leedahay waxqabadka buuxinta sare waxaana laga dhigi karaa alaab buuxisa shuruudaha waxqabadka kala duwan.CPE waxay leedahay hawlkarnimo wanaagsan, Mooney viscosity (ML121 1+4) waxay u dhaxaysaa 50-100, waxaana jira darajooyin badan oo laga dooran karo.
