Liphaephe tsa PVC le CPVC ke eng?

Liphaephe tsa PVC

E thehiloe lilemong tsa bo-1930, liphaephe tsa PVC (polyvinyl chloride) e se e le tekanyetso ea lipeipi tsa masepala le tsa indasteri lefatšeng ka bophara.United States, likarolo tse tharo ho tse tharo tsa matlo ohle li sebelisa PVC.Ho tloha lilemong tsa bo-1950, e fetohile sebaka se tloaelehileng sa liphaephe tsa tšepe

PVC e etsoa ho sebelisoa e 'ngoe ea mekhoa e meraro ea polymerization: polymerization ea ho emisa, emulsion polymerization, kapa polymerization e ngata.Boholo ba PVC bo entsoe ka ho fanyeha polymerization.

Ke habohlokoa ho hlokomela hore liphaephe tsa PVC li tla ka mefuta e 'meli: e thata le e sa polasetiki.Sebopeho se thata ho ka etsahala hore ebe ke sona sa pele se tlang kelellong - nahana ka metsi a nooang, lipeipi tsa metsi, likhoerekhoere le temo.Foromo e se nang polasetiki e bonolo, e leng molemo bakeng sa ho sebelisoa lits'ebetsong tse kang li-tubing tsa bongaka le ho kenya letsoho bakeng sa lithapo tsa motlakase.

Melemo e meng ea phala ea PVC e kenyelletsa matla a eona, ho tšoarella ho phahameng, litšenyehelo tse tlase, ho kenya habonolo, le ho hanyetsa mafome le ho bola.

Liphaephe tsa CPVC

CPVC ha e le hantle ke PVC e kentsoeng chlorinated.Ts'ebetso ea chlorination e lumella CPVC ho mamella mocheso o phahameng-ho fihla ho 200 ° F-'me e ntlafatsa ho hanyetsa mollo le ho bola ha eona.Ka lebaka la ho hanyetsa mocheso o phahameng, mekhoa e mengata ea mohaho e hloka liphaephe tsa CPVC bakeng sa lisebelisoa tsa metsi a chesang, le hoja e ka sebelisoa bakeng sa metsi a chesang le a batang.Ho feta moo, CPVC e kenyellelitsoe haholo ts'ebelisong ea lisebelisoa tsa ho fafatsa mollo.

Ka lebaka la bokhoni ba eona ba ho mamella mocheso o phahameng le mefuta e mengata ea mekhoa ea khoebo le ea indasteri, CPVC e tla ka theko e phahameng ho feta PVC.

Phapang ke efe lipakeng tsa liphaephe tsa PVC le CPVC?

Phapang e kholo lipakeng tsa PVC le CPVC ke bokhoni ba tsona ba ho mamella mocheso.Joalokaha ho boletsoe pejana, phala ea CPVC e ka mamella ho fihla ho 200 ° F, athe pipe ea PVC e khona ho mamella ho fihlela ho 140 ° F.Haeba u feta ka holim'a mocheso oo, bobeli bo tla qala ho kokobela, e leng se ka etsang hore manonyeletso a fokotsehe 'me liphaephe li hlōlehe.Ka lebaka leo, li-plumbers tse ngata li tla u khothalletsa hore u sebelise CPVC bakeng sa melapo ea metsi a chesang le PVC bakeng sa melapo ea metsi a batang.

Le hoja PVC e na le melemo e mengata, CPVC e na le maemo a mangata, 'me e fumaneha ka bobeli ba boholo ba liphaephe (NPS) le boholo ba tube ea koporo (CTS).Ka lehlakoreng le leng, PVC e fumaneha feela tsamaisong ea NPS.Liphaephe ka bobeli li fumaneha ka bolelele ba 10 ft le 20 ft.

Mabapi le ponahalo, liphaephe tsa PVC li na le 'mala o mosoeu kapa o lefifi,' me liphaephe tsa CPVC hangata li tšoeu, li le bohlooho bo khanyang kapa li mosehla.Haeba ho na le potso leha e le efe, bobeli ba bona ba tla ba le litlhaloso tsa bona tsa tekheniki ka lehlakoreng.Kaha metsoako ea lik'hemik'hale e fapana pakeng tsa tse peli, lisamente tse qhibilihisang le li-bonding agents ha lia lokela ho sebelisoa ka mokhoa o fapaneng.

Ho tšoana hofe pakeng tsa liphaephe tsa PVC le CPVC?

Ha ho tluoa tabeng ea ho tšoana ha tekheniki le 'mele, PVC le CPVC li na le lethathamo le tsotehang la melemo.Bakeng sa e 'ngoe, thepa ea liphaephe ka bobeli e ba lumella ho hanela kutu le ho senyeha ha lik'hemik'hale.Taba ea bobeli, ka bobeli li bolokehile ho sebelisoa ka metsi a nooang ha ANSI / NSF 61 e netefalitsoe.Ka bobeli li tla ka Setulo sa 40 le Botenya ba Kemiso ea 80, 'me li fumaneha ka mokhoa o hlakileng le qetellong ea tšepe.Ho feta moo, Schedule 40 PVS e tla ka li-fittings tsa Sehlopha sa 125.
