I. Iimpawu zezinto eziphathekayo:

I-PVC yenziwe nge-vinyl chloride monomer (VCM) i-polymerization, imathiriyeli ye-PVC ine-non-toxic, anti-aging kunye ne-asidi kunye neempawu zokumelana ne-alkali, ngoko ifaneleke kakhulu ukusetyenziswa kwemibhobho yemichiza.Kwaye kunye PVC izinto ekrwada ukongeza umlinganiselo othile izongezo eziqinileyo (akukho plasticizer) ukubunjwa umxube, ebizwa polyvinyl chloride nzima (ekubhekiselwe kuyo UPVC).

I-CPVC yimathiriyeli ye-polymer eguqulwe nge-chlorination ye-polyvinyl chloride (PVC) kwakhona.Emva kwe-chlorine, umxholo we-chlorine we-PVC we-resin uyanda ukusuka kwi-56.7% ukuya kwi-63-69%, eyandisa ukuzinza kweekhemikhali kwaye ngaloo ndlela iphucula ukumelana nobushushu kunye nokumelana nokubola kwe-asidi, i-alkali, ityuwa kunye ne-oxidant yezinto.Ubushushu be-thermal deformation kunye neempawu zoomatshini ziphezulu kakhulu kunezo ze-UPVC.Ke ngoko, i-CPVC yenye yezona zinto zibalaseleyo zobunjineli kwimibhobho yeshishini.

2. Intshayelelo yenkqubo yemibhobho:

Inkqubo yemibhobho ye-UPVC kunye ne-CPVC inokumelana nomhlwa, ukuxhathisa impembelelo, akukho lula ukuguqulwa, udonga lwangaphakathi olugudileyo, akukho lula ukukala, ukugqunyelelwa kakuhle kwe-thermal, ukungahambi kakuhle, ukuxhamla, ubomi obude benkonzo kunye nezinye iimpawu.Ngoko ke, ngokuthe ngcembe ithatha indawo yezinye iinkqubo zemibhobho yesinyithi kwiinzuzo zokusebenza kweendleko eziphezulu kunye neendleko eziphantsi zokwakha, kunye neenkqubo zemibhobho ye-UPVC kunye ne-CPVC zilungele kwaye zigcinwa ngokukhawuleza, ngaphandle kwexesha elide kunye nelahleko enkulu, ngoko ke iinkqubo zemibhobho ye-UPVC kunye ne-CPVC zikhetho lokuqala. kuyilo lwemibhobho yoshishino lwangoku.

Ubushushu benkonzo obuphezulu obuvumelekileyo benkqubo yemibhobho ye-UPVC yi-60 ℃, kwaye ubushushu benkonzo yexesha elide yi-45 ℃.Ilungele ukuhambisa ezinye imidiya ezonakalisayo ezinobushushu obungaphantsi kwe 45℃;Ingasetyenziselwa ukuthutha ulwelo oluqhelekileyo loxinzelelo, olusetyenziswa ngokubanzi kunikezelo lwamanzi kunye nemibhobho yokuhambisa amanzi, imibhobho yokunkcenkceshela yezolimo, imibhobho yobunjineli bokusingqongileyo, imibhobho yomoya womoya njalo njalo.

Ubushushu benkonzo obuphezulu obuvumelekileyo benkqubo yemibhobho ye-CPVC yi-110 ℃, kwaye iqondo lobushushu benkonzo yexesha elide yi-95 ℃.Ifanelekile ukuhambisa amanzi ashushu kunye neendaba ezitshabalalisayo ngaphakathi koxinzelelo oluvumelekileyo lomgangatho.Isetyenziswa ngokubanzi kwi-petroleum, ikhemikhali, i-elektroniki, amandla ombane, isinyithi, iphepha, ukutya kunye nesiselo, amayeza, i-electroplating kunye namanye amasimi amashishini.
