Tisati tapinda muchirevo ichi, ngatitangei taongorora kuti chinhu chimwe nechimwe chakagadzirwa nei. PPR ipfupiso ye polypropylene random copolymer, nepo CPVC iri chlorinated polyvinyl chloride iyo inogadzirwa kuburikidza nekuita chlorination kuita polyvinyl chloride.
PPR ndiyo nzira inonyanya kushandiswa muEurope, Russia, South America, Africa, South Asia, China neMiddle East, ukuwoCPVCinonyanya kushandiswa muIndia neMexico. PPR iri nani pane CPVC kwete nekuda kwekuti inogamuchirwa nevanhu vakawanda, uye yakachengeteka kunwa mvura.
Zvino, ngatikubatsirei kuita sarudzo yakachengeteka, kunzwisisa kuti sei CPVC pombi isina kuchengetedzeka uye nei muchifanira kusarudzaMapombi ePPR.

Plastiki yemhando yechikafu:
Mapaipi ePPR haana zvinhu zvinobva muchlorine uye akachengeteka mumuviri wemunhu, nepo chimiro chemapaipi eCPVC chine chlorine, iyo inogona kupatsanurwa nekunyungudutswa mumvura muchimiro chevinyl chloride uye inoungana mumuviri wemunhu.
Mune zvimwe zviitiko, kubuda kwemvura kwakawanikwa mumapaipi eCPVC nekuti haana kunamira zvakanaka uye anoda mishonga inonyungudutsa, nepo mapaipi ePPR akabatanidzwa pamwe chete nekupisa uye kudzivirira mapaipi akakora uye kunamira kwakasimba. Simba rakabatana rinotungamira kune chero rudzi rwekubuda kwemvura. United States yakaita zvidzidzo zvakawanda pamusoro pekubuda kwezvinhu zvine njodzi zvakaita sechloroform, tetrahydrofuran uye acetate mumvura yekunwa kuburikidzaMapaipi eCPVC.

Zvinonyungudutsa zvinoshandiswa muCPVC zvinoisa hutano hwako panjodzi:

California Pipeline Trade Commission ine basa rekuongorora migumisiro yehutano hwemapombi uye ndiyo kambani inopa zvitupa zvemapombi muCalifornia, USA. Yagara ichitsigira zvikuru migumisiro ine njodzi yezvinyungudutsa zvinoshandiswa kubatanidza mapombi eCPVC. Zvakaonekwa kuti chinonyungudutsa chine zvinhu zvinokonzera kenza mumhuka uye chinoonekwa sechinogona kukuvadza vanhu. Kune rumwe rutivi, mapombi ePPR haadi chero zvinonyungudutsa uye anobatanidzwa netekinoroji yekunyungudutsa inopisa, saka haana makemikari ane chepfu.

Nzira yePPR ndiyo mhinduro ine hutano:
Mapaipi eKPT PPR akagadzirwa nezvinhu zvemhando yepamusoro, zvemhando yepamusoro, zvinochinjika, zvakasimba, uye zvinogona kutsungirira tembiricha iri pakati pe -10°C kusvika 95°C. Mapaipi eKPT PPR ane hupenyu hwakareba hwekushanda, hunogona kushandiswa kwemakore anopfuura makumi mashanu.
