Soosaarayaasha CPE Polyethylene Chlorinated
Tifaftiraha soo saaraha wakiilka gabowga ayaa maanta kuu soo bandhigaya hordhaca ku habboon ee ku saabsan soo saaraha koloriinta polyetylen. Kolorinated polyetylen (CPE) waa shey loo isticmaalo soosaarka kiimikada. Dad badan ayaan ka aqoon chloride vinyl chloride. Fahmo, soo gaabinta Ingiriisiga ee polyetylen koloriinku waa: CPE ama cm, chlorinated polyethylene (CPE) waa maaddo polymer ah oo buuxa, muuqaalkuna waa budo cad, aan sun ahayn oo aan dhadhan lahayn, oo leh iska caabin cimilo oo heer sare ah, iska caabin ozone, caabbinta kiimikada iyo iska caabinta gabowga. , Saliida iska caabbinta wanaagsan, dib u dhaca ololka iyo sifooyinka iftiinka. Adayg wanaagsan (wali waa u dabacsan yahay -30 ° C), ku habboonaanta wanaagsan ee qalabka kale ee polymer, heerkulka sare ee burburka, kala-goynta HCl, HCl waxay kicin kartaa falcelinta dechlorination ee CPE.
Polyethylene Chlorinated (HDPE) waa walxo polymer ah oo laga sameeyay polyetylen cufnaanta sare leh (HDPE) ee koloriinta Sida laga soo xigtay qaab-dhismeedka iyo isticmaalka kala duwan, polyetylen koloriinaysan waxa loo qaybin karaa resin koloriinated polyethylene (CPE) iyo elastic chlorinated polyethylene (CM). Waxa kale oo lagu dhex qasi karaa xabagta-thermoplastic ee keligood la isticmaali karo, waxa kale oo lagu qasi karaa polyvinyl chloride (PVC), polyetylen (PE), polypropylene (PP), polystyrene (PS), resin ABS iyo xataa polyurethane (PU). Warshadaha caagga ah, CPE waxaa loo isticmaali karaa sidii wax-qabad sare, caag gaar ah oo tayo sare leh, waxaana sidoo kale loo isticmaali karaa caag ethylene-propylene (EPR), rubber butyl (IIR), nitrile rubber (NBR), chlorosulfonated polyethylene CSM) Ku isticmaal xeryahooda caag kale.
Astaamaha Polyethylene Chlorinated
1) CPE ma aha sun, kuma jiraan biro culus iyo hydrocarbons caraf udgoon polycyclic, oo si buuxda u buuxiya shuruudaha ilaalinta deegaanka.
2) CPE waxay leedahay iska caabin saliid oo heer sare ah, gaar ahaan ASTM1 iyo ASTM2 saliidaha, oo u dhigma NBR; iska caabin heer sare ah oo saliidaha ASTM3, oo ka fiican CR oo la barbar dhigi kara CSM.
3) CPE waxay leedahay waxqabadka buuxinta sare waxaana laga samayn karaa alaabooyin buuxiya shuruudaha waxqabadka kala duwan. CPE waxay leedahay farsamayn aad u wanaagsan waxaana laga heli karaa Mooney viscosity (ML1211+4) darajooyinka u dhexeeya 50 ilaa 100.
4) CPE waa caag buuxa oo leh gabowga anti-oxidative, gabowga anti-ozone, caabbinta acid iyo alkali iyo sifooyinka kiimikada.
5) CPE waxay ka kooban tahay walxo koloriin ah, waxay leedahay sifooyin dib-u-dhigista ololka oo aad u wanaagsan, waxayna leedahay sifooyinka gubashada ka hortagga. Dab-demiska ku salaysan antimony, paraffin koloriin ku jira iyo Al(OH)3 ayaa si wada jir ah loo isticmaalaa si loo helo walxo ololka celisa oo leh wax qabad wanaagsan oo olol iyo qiimo jaban.
