Ma mua o ke komo ʻana i ka kikoʻī, e ʻike mua kākou i ka mea i hana ʻia ai kēlā me kēia mea. ʻO PPR ka pōkole o ka polypropylene random copolymer, ʻoiai ʻo CPVC he polyvinyl chloride chlorinated i hana ʻia ma o ke kaʻina hana o ka chlorination i polyvinyl chloride.
ʻO PPR ka ʻōnaehana paipu i hoʻohana nui ʻia ma ʻEulopa, Rusia, ʻAmelika Hema, ʻApelika, ʻAsia Hema, Kina a me ka Hikina Waena, ʻoiai ʻo ka ....CPVChoʻohana nui ʻia ma India a me Mekiko. ʻOi aku ka maikaʻi o ka PPR ma mua o CPVC ʻaʻole ma muli o kona ʻae ʻia ʻana, a palekana ia no ka wai inu.
I kēia manawa, e kōkua mākou iā ʻoe e hana i kahi hoʻoholo palekana, e hoʻomaopopo i ke kumu he palekana ʻole ka piping CPVC a no ke aha ʻoe e makemake aiNā paipu PPR.

Palakiko papa meaʻai:
ʻAʻole i loko o nā paipu PPR nā derivatives chlorine a palekana no ke kino o ke kanaka, ʻoiai ʻo ka ʻōnaehana paipu CPVC he chlorine, hiki ke hoʻokaʻawale a hoʻoheheʻe ʻia i ka wai ma ke ʻano o ka vinyl chloride a hōʻiliʻili i loko o ke kino o ke kanaka.
I kekahi mau hihia, ua ʻike ʻia ka leaching ma ke ʻano o nā paipu CPVC no ka mea he palupalu ko lākou hoʻopili ʻana a koi i nā mea hoʻoheheʻe kemika, ʻoiai ua hui pū ʻia nā paipu PPR e ka fusion wela a pale i nā paipu mānoanoa a me ka hoʻopili ikaika. ʻO nā mana i hui pū ʻia e alakaʻi i kekahi ʻano leakage. Ua hana ʻo ʻAmelika Hui Pū ʻIa i nā haʻawina he nui e pili ana i ka leaching o nā mea weliweli e like me chloroform, tetrahydrofuran a me acetate i loko o ka wai inu ma oNā paipu CPVC.

ʻO nā mea hoʻoheheʻe i hoʻohana ʻia ma CPVC e hoʻopilikia i kou olakino:

ʻO ke Komisina Kālepa Paipu Kaleponi ke kuleana no ka loiloi ʻana i nā hopena olakino o nā ʻōnaehana paipu a ʻo ia ke keʻena hōʻoia plumber ma Kaleponi, USA. Ua kākoʻo mau ia i nā hopena weliweli o nā solvents i hoʻohana ʻia e hoʻopili i nā paipu CPVC. Ua ʻike ʻia aia nā mea carcinogenic i loko o ka solvent i nā holoholona a ua manaʻo ʻia he mea hōʻino paha i nā kānaka. Ma ka ʻaoʻao ʻē aʻe, ʻaʻole pono nā paipu PPR i nā solvents a ua hoʻopili ʻia e ka ʻenehana hoʻoheheʻe wela, no laila ʻaʻole lākou i loaʻa nā kemika ʻawahia.

ʻO ka pipeline PPR ka pane olakino:
Hana ʻia nā paipu KPT PPR me nā mea maka kiʻekiʻe, kūpono i ka meaʻai, palupalu, ikaika, a hiki ke kū i kahi mahana mai -10°C a 95°C. He lōʻihi loa ke ola lawelawe o nā paipu KPT PPR, hiki ke hoʻohana ʻia no nā makahiki he 50 a ʻoi.
