I mua i te whakaurunga o ngā whakatakotoranga, me mārama tātou ki te hanganga o ia rauemi. Ko te PPR te whakarāpopototanga o te polypropylene random copolymer, ko te CPVC ia he polyvinyl chloride kua whakakōkōhia ki te chlorine, ka puta mai i te tukanga whakakōkōhia ki te polyvinyl chloride.
Ko te PPR te pūnaha paipa e whakamahia whānuitia ana i Ūropi, Rūhia, Amerika ki te Tonga, Āwherika, Āhia ki te Tonga, Haina me te Middle East, i te wāCPVCe whakamahia nuitia ana i Īnia me Mehiko. He pai ake te PPR i te CPVC, ehara i te mea nā te whānui o te whakamahinga, ā, he haumaru hoki mō te wai inu.
Nā, me āwhina koe e mātou ki te whakatau haumaru ake, kia mārama ai he aha te haumaru o ngā paipa CPVC, me te aha hoki me whiriwhiri koe i tētahi atuNgā paipa PPR.

Kirihou kai:
Kāore he matū hauwai i roto i ngā paipa PPR, ā, he haumaru mō te tinana tangata, engari kei roto i te hanganga paipa CPVC he hauwai, ka taea te wehe me te whakarewa ki te wai hei vinyl chloride ka kohia ki roto i te tinana tangata.
I ētahi wā, kua kitea te turuturu i roto i ngā paipa CPVC nā te mea he ngoikore te piri, ā, me whakamahi i ngā whakarewa matū, ko ngā paipa PPR ia ka honoa mā te hanumi wera, ā, ka ārai i ngā paipa matotoru me te piri kaha. Mā ngā kaha whakakotahi ka puta he momo turuturu. He maha ngā rangahau a te Hononga o Amerika mō te turuturu o ngā matū kino pērā i te chloroform, tetrahydrofuran me te acetate ki roto i te wai inu mā roto iNgā paipa CPVC.

Ka tūkinotia tō hauora e ngā whakarewa e whakamahia ana i roto i te CPVC:

Ko te California Pipeline Trade Commission te kawenga mō te arotake i ngā pānga hauora o ngā pūnaha paipa, ā, ko rātou te tari tiwhikete paramu i California, USA. Kua roa e tautoko ana i ngā pānga kino o ngā whakarewa e whakamahia ana hei hono i ngā paipa CPVC. Kua kitea kei roto i te whakarewa ngā āhuatanga mate pukupuku i roto i ngā kararehe, ā, e kiia ana he kino pea ki te tangata. I tētahi atu taha, kāore e hiahiatia he whakarewa mō ngā paipa PPR, ā, ka honoa mā te hangarau rewa wera, nō reira kāore he matū paitini i roto.

Ko te paipa PPR te whakautu pai:
He mea hanga ngā paipa PPR KPT ki ngā rauemi mata kounga teitei, he mea hanga ki te kai, he ngāwari, he kaha, ā, ka taea te tu atu i ngā pāmahana mai i te -10°C ki te 95°C. He roa te ora o ngā paipa PPR KPT, ā, ka taea te whakamahi mō ngā tau neke atu i te 50.
