I. Izici zezinto ezibonakalayo:

I-PVC yenziwe nge-vinyl chloride monomer (VCM) polymerization, impahla ye-PVC inezici ezingenabuthi, ezilwa nokuguga kanye ne-asidi kanye ne-alkali yokumelana, ngakho ifaneleka kakhulu ukusetshenziswa kwepayipi lamakhemikhali.Futhi ngezinto zokusetshenziswa ze-PVC zokwengeza inani elithile lezithasiselo eziqinile (akukho plasticizer) ukwakheka kwengxube, okubizwa nge-polyvinyl chloride eqinile (okubizwa ngokuthi i-UPVC).

I-CPVC iwumsebenzi we-polymer oshintshwe nge-chlorination ye-polyvinyl chloride (PVC) futhi.Ngemuva kwe-chlorine, okuqukethwe kwe-chlorine ye-PVC resin kukhuphuka kusuka ku-56.7% kuya ku-63-69%, okwandisa ukuzinza kwamakhemikhali futhi ngaleyo ndlela kuthuthukise ukumelana nokushisa nokumelana nokugqwala kwe-asidi, i-alkali, usawoti kanye ne-oxidant yezinto.Izinga layo lokushisa lokushintsha okushisayo kanye nezakhiwo zemishini ziphakeme kakhulu kunalezo ze-UPVC.Ngakho-ke, i-CPVC ingenye yezinto ezinhle kakhulu zobunjiniyela zamapayipi ezimboni.

2. isingeniso sesistimu yamapayipi:

I-UPVC ne-CPVC yamapayipi amapayipi anokumelana nokugqwala, ukumelana nomthelela, akulula ukuwohloka, udonga lwangaphakathi olubushelelezi, akulula ukukala, ukwahlukanisa okuhle okushisayo, okungaqhubeki, ukubopha okulula, impilo ende yesevisi nezinye izici.Ngakho-ke, kancane kancane ithatha indawo yezinye izinhlelo zamapayipi ensimbi ngezinzuzo zokusebenza kwezindleko eziphakeme kanye nezindleko eziphansi zokwakha, futhi izinhlelo zamapayipi ze-UPVC ne-CPVC zilula futhi zilungiswa ngokushesha, ngaphandle kokunciphisa isikhathi eside nokulahlekelwa okukhulu, ngakho-ke amapayipi e-UPVC kanye ne-CPVC ayisinqumo sokuqala. ngomklamo wamanje wamapayipi wezimboni.

Izinga lokushisa eliphezulu elivumelekile lesevisi le-UPVC lamapayipi lingu-60 ℃, kanti izinga lokushisa lesevisi yesikhathi eside lingu-45 ℃.Ilungele ukudlulisa imidiya eyonakalisayo enezinga lokushisa elingaphansi kuka-45 ℃;Ingase futhi isetshenziselwe ukuthuthwa koketshezi oluvamile lwe-pressure, oluvame ukusetshenziswa ekunikezeni amanzi kanye namapayipi okukhipha amanzi, amapayipi okunisela ezolimo, amapayipi onjiniyela bemvelo, amapayipi omoya omoya njalonjalo.

Izinga lokushisa eliphezulu elivumelekile lensizakalo yesistimu yamapayipi e-CPVC ngu-110 ℃, futhi izinga lokushisa lesevisi yesikhathi eside lingu-95 ℃.Ifanele ukudlulisa amanzi ashisayo nemidiya ebolayo ngaphakathi kwebanga lokucindezela elivumelekile lezinga.Ivame ukusetshenziswa ku-petroleum, amakhemikhali, i-electronic, amandla kagesi, i-metallurgy, iphepha, ukudla nesiphuzo, imithi, i-electroplating kanye neminye imikhakha yezimboni.
