Iimveliso ze-PVC ezinogwebu zimhlophe, kodwa ngamanye amaxesha ziba tyheli xa zigcinwe ixesha elide. Siyintoni isizathu? Okokuqala, kufuneka uqonde ukuba kukho ingxaki kwi-arhente ekhethiweyo yogwebu. Umlawuli we-PVC ogwebu amagwebu usebenzisa i-arhente yogwebu ukubola kunye nokuvelisa igesi ebangela iipores. Xa iqondo lokushisa lokucubungula linokufikelela kwiqondo lokushisa lokubola kwe-ejenti ekhupha amagwebu, ngokwemvelo ayiyi kuphosa. Iindidi ezahlukeneyo zee-agent ezinegwebu zineqondo lokushisa elihlukeneyo lokubola, nokuba uhlobo olufanayo lwe-ejenti yogwebu lwenziwe ngabavelisi abahlukeneyo, ubushushu bokubola bungenakufana ncam. Khetha isilawuli sogwebu sePVC esilungele wena. Ayizizo zonke iPVC ezilungele ugwebu, ngoko ke kuyafuneka ukuba ukhethe izixhobo ezineqondo eliphantsi lepolymerization ukuze kusetyenzwe.

Okokuqala, kufuneka uqonde ukuba kukho ingxaki kwi-arhente ekhethiweyo yogwebu. Umlawuli we-PVC ogwebu amagwebu usebenzisa i-arhente yogwebu ukubola kunye nokuvelisa igesi ebangela iipores. Xa iqondo lokushisa lokucubungula linokufikelela kwiqondo lokushisa lokubola kwe-ejenti ekhupha amagwebu, ngokwemvelo ayiyi kuphosa. Iindidi ezahlukeneyo zee-agent ezinegwebu zineqondo lokushisa elihlukeneyo lokubola, nokuba uhlobo olufanayo lwe-ejenti yogwebu lwenziwe ngabavelisi abahlukeneyo, ubushushu bokubola bungenakufana ncam. Khetha isilawuli sogwebu sePVC esilungele wena. Ayizizo zonke iPVC ezilungele ugwebu, ngoko ke kuyafuneka ukuba ukhethe izixhobo ezineqondo eliphantsi lepolymerization. Izinto ezinjalo zineqondo lokushisa eliphantsi, njenge-S700. Ukuba ufuna ukusebenzisa i-1000 kunye ne-700, inokwahluka. I-arhente yogwebu inokuba sele ibolile kwaye iPVC ayikanyibiliki.
Ukongeza, kukho ezinye izongezo. Iqondo lobushushu lokubola ye-arhente eqhelekileyo amagwebu liphezulu kunobushushu processing of PVC. Ukuba izongezo ezifanelekileyo azifakwanga, umphumo kukuba i-PVC iyabola (ijika ibe tyheli okanye ibe mnyama) kwaye i-ACR ayikaboli (amagwebu). Ngoko ke, kuyimfuneko ukongeza i-stabilizers ukugcina i-PVC izinzile (ayikuboli kwiqondo lokushisa le-AC). Kwelinye icala, izongezelelo ezikhuthaza ugwebu lwe-AC zongezwa ukunciphisa ubushushu bokubola kwe-AC kwaye zidityaniswe nayo. Kukho kwakhona izongezo zokwenza i-foam pores ibe yincinci kwaye ixinene, oko kukuthi ukuphepha iipores ezinkulu eziqhubekayo kunye nokunciphisa amandla emveliso. Ekubeni iqondo lobushushu lisezantsi kwaye alisajiki tyheli, ndinokuqinisekisa ukuba ubushushu bakho obuphezulu bangaphambili bubangele ukuba iPVC ibole kwaye ijike ibe tyheli. Ukubola kwePVC yindlela yokuzikhuthaza, nto leyo ethetha ukuba izinto ezibolileyo zikhuthaza ukubola ngakumbi. Ngoko ke, ngokuqhelekileyo kubonakala ukuba kulungile ukuba iqondo lokushisa alikho phezulu, kodwa ukuba izinga lokushisa liphezulu kakhulu, liya kubola ngobuninzi.
