Yiziphi izizathu zokushintshwa kombala kwezilawuli ze-PVC ezinegwebu

Imikhiqizo ye-PVC eyenza amagwebu imhlophe, kodwa ngezinye izikhathi iba phuzi uma igcinwe isikhathi eside.Siyini isizathu?Okokuqala, udinga ukunquma ukuthi ngabe kunenkinga nge-ejenti ekhethiwe yokugwedla.Isilawuli se-PVC esenza amagwebu sisebenzisa i-ejenti ekhihlizayo ukubola nokukhiqiza igesi ebangela izimbotshana.Lapho izinga lokushisa lokucubungula lingafinyelela izinga lokushisa lokubola le-ejenti enegwebu, ngokwemvelo ngeke libe negwebu.Izinhlobo ezihlukene zama-ejenti agwebu zinamazinga okushisa ahlukene okubola, ngisho noma uhlobo olufanayo lwe-ejenti enegwebu lukhiqizwa abakhiqizi abahlukene, izinga lokushisa lokubola lingase lingafani ncamashi.Khetha isilawuli sogwebu se-PVC esikufanele.Akuwona wonke ama-PVC alungele ukugwaza, ngakho-ke kuyadingeka ukukhetha izinto ezineziqu eziphansi ze-polymerization ukuze zicutshungulwe.

Okokuqala, udinga ukunquma ukuthi ngabe kunenkinga nge-ejenti ekhethiwe yokugwedla.Isilawuli se-PVC esenza amagwebu sisebenzisa i-ejenti ekhihlizayo ukubola nokukhiqiza igesi ebangela izimbotshana.Lapho izinga lokushisa lokucubungula lingafinyelela izinga lokushisa lokubola le-ejenti enegwebu, ngokwemvelo ngeke libe negwebu.Izinhlobo ezihlukene zama-ejenti agwebu zinamazinga okushisa ahlukene okubola, ngisho noma uhlobo olufanayo lwe-ejenti enegwebu lukhiqizwa abakhiqizi abahlukene, izinga lokushisa lokubola lingase lingafani ncamashi.Khetha isilawuli sogwebu se-PVC esikufanele.Akuwona wonke ama-PVC afaneleka ukwenza amagwebu, ngakho-ke kuyadingeka ukukhetha izinto ezineziqu eziphansi ze-polymerization.Izinto ezinjalo zinezinga lokushisa eliphansi lokucubungula, njenge-S700.Uma ufuna ukusebenzisa u-1000 no-700, kungase kuhluke.I-ejenti ekhipha amagwebu kungenzeka ukuthi isivele ibolile futhi i-PVC ayikancibiliki.

Ngaphezu kwalokho, kunezinye izithasiselo.Izinga lokushisa lokubola le-ejenti elenza amagwebu elivamile lingaphezulu kwezinga lokushisa lokucubungula le-PVC.Uma izithasiselo ezifanele zingengezwe, umphumela uba ukuthi i-PVC iyabola (iphenduka ibe phuzi noma ibe mnyama) futhi i-ACR ayikaboli (amagwebu).Ngakho-ke, kuyadingeka ukwengeza iziqinisi ukugcina i-PVC izinzile (ayiboli ekushiseni kwesilingo se-AC).Ngakolunye uhlangothi, izithasiselo ezikhuthaza ukugwebulwa kwe-AC ziyengezwa ukuze kuncishiswe izinga lokushisa lokubola le-AC futhi lihambisane nayo.Kukhona futhi izithasiselo zokwenza ama-foam pores amancane futhi aminyene, okuwukugwema ama-foam amakhulu aqhubekayo futhi unciphise amandla omkhiqizo.Njengoba izinga lokushisa liphansi futhi lingasaphuzi, ngingaqinisekisa ukuthi izinga lokushisa lakho eliphezulu langaphambilini libangele ukuthi i-PVC ibole futhi ibe phuzi.Ukubola kwe-PVC kuyindlela yokuzithuthukisa, okusho ukuthi izinto ezibolile zithuthukisa ukubola okwengeziwe.Ngakho-ke, kuvame ukubonakala ukuthi kulungile uma izinga lokushisa lingekho phezulu, kodwa uma izinga lokushisa liphakeme kancane, lizobola ngobuningi.
