Soo-saareyaasha CPE ee Polyethylene ee Koloriinaysan
Tifaftiraha soo saaraha wakiilka ka hortagga gabowga ayaa maanta kuu soo bandhigi doona hordhaca khuseeya ee ku saabsan soo saaraha polyethylene-ka kloriinaysan ee cpe. Polyethylene-ka kloriinaysan (CPE) waa badeecad loo isticmaalo wax soo saarka kiimikada. Dad badan ma yaqaaniin vinyl chloride chloride. Fahmaan, soo gaabinta Ingiriisiga ee polyethylene-ka kloriinaysan waa: CPE ama cm, polyethylene-ka kloriinaysan (CPE) waa walxo polymer ah oo buuxa, muuqaalku waa budo cad, aan sun ahayn oo aan dhadhan lahayn, oo leh iska caabin cimilo oo aad u fiican, iska caabin ozone ah, iska caabin kiimiko iyo iska caabin gabowga, iska caabin saliid oo wanaagsan, iska caabin olol iyo sifooyin gaashaan iftiin. Adkayn wanaagsan (wali dabacsan -30°C), iswaafajin wanaagsan oo leh agabyada kale ee polymer-ka, heerkulka kala-baxa sare, kala-baxa HCl, HCl wuxuu kicin karaa falcelinta dechlorination ee CPE.
Polyethylene-ka Chlorinated (HDPE) waa walax polymer ah oo laga sameeyay polyethylene-ka cufnaanta sare leh (HDPE) iyadoo lagu darayo koloriin. Sida ku xusan qaab-dhismeedka iyo isticmaalka kala duwan, polyethylene-ka klorinated waxaa loo qaybin karaa polyethylene-ka klorinated resin (CPE) iyo polyethylene-ka elastic chlorinated (CM). Marka lagu daro resins-ka thermoplastic-ka ee keligood la isticmaali karo, waxaa sidoo kale lagu qasi karaa polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), resin ABS iyo xitaa polyurethane (PU). Warshadaha caagga, CPE waxaa loo isticmaali karaa caag gaar ah oo tayo sare leh, waxaana sidoo kale loo isticmaali karaa caag ethylene-propylene (EPR), caag butyl (IIR), caag nitrile (NBR), polyethylene-ka klorinsulfonated (CSM) Isticmaal isku-darka caagga kale.
Sifooyinka Polyethylene-ka Koloriinta leh
1) CPE ma aha sun, kama koobna biraha culus iyo hydrocarbons-ka udgoonka badan, waxayna si buuxda u buuxisaa shuruudaha ilaalinta deegaanka.
2) CPE waxay leedahay iska caabin saliideed oo aad u fiican, gaar ahaan saliidaha ASTM1 iyo ASTM2, oo la mid ah NBR; iska caabin aad u fiican oo saliidaha ASTM3 ah, oo ka wanaagsan CR oo la mid ah CSM.
3) CPE waxay leedahay waxqabad buuxa oo heer sare ah waxaana laga samayn karaa badeecooyin buuxiya shuruudaha waxqabadka kala duwan. CPE waxay leedahay mashiin aad u fiican waxayna ku jirtaa viscosity Mooney (ML1211+4) oo u dhexeeya 50 ilaa 100.
4) CPE waa caag buuxa oo leh gabowga ka hortagga oksaydhka oo aad u fiican, gabowga ka hortagga ozone, iska caabbinta aashitada iyo alkali iyo sifooyin kiimiko ah.
5) CPE waxay ka kooban tahay walxo koloriin ah, waxay leedahay sifooyin aad u fiican oo ka hortagga dabka, waxayna leedahay astaamo ka hortagga gubashada. Qalabka ka hortagga dabka ee ku salaysan antimony, paraffin-ka koloriinaysan iyo Al(OH)3 ayaa si wada jir ah loo isticmaalaa si loo helo walxo ka hortaga dabka oo leh waxqabad wanaagsan oo ka hortagga dabka iyo kharash yar.
