Ma mua o ke komo ʻana i ka kikoʻī, e noʻonoʻo mua kākou i ke ʻano o kēlā me kēia mea i hana ʻia. ʻO ka PPR ka pōkole o ka polypropylene random copolymer, aʻo ka CPVC he chlorinated polyvinyl chloride i hana ʻia ma ke kaʻina hana o ka chlorination i ka polyvinyl chloride.
ʻO PPR ka ʻōnaehana paipu i hoʻohana nui ʻia ma ʻEulopa, Russia, ʻAmelika Hema, ʻApelika, ʻAsia Hema, Kina a me ka Middle East, ʻoiaiCPVCHoʻohana nui ʻia ma India a me Mexico. ʻOi aku ka maikaʻi o ka PPR ma mua o ka CPVC ʻaʻole ma muli o kona ʻae ākea, a palekana no ka wai inu.
I kēia manawa, e kōkua mākou iā ʻoe e hana i kahi hoʻoholo palekana, e hoʻomaopopo i ke kumu palekana ʻole ka paipu CPVC a no ke aha ʻoe e makemake ai.PPR paipu.

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

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

ʻO ka California Pipeline Trade Commission ke kuleana no ka nānā ʻana i nā hopena olakino o nā ʻōnaehana paipu a ʻo ia ke keʻena hōʻoia plumber ma Kaleponi, USA. Ua kākoʻo nui ʻo ia i nā hopena pōʻino o nā solvents i hoʻohana ʻia e hoʻopili i nā paipu CPVC. Ua ʻike ʻia aia ka mea hoʻoheheʻe i nā mea carcinogenic i loko o nā holoholona a manaʻo ʻia he mea pōʻino i ke kanaka. Ma ka ʻaoʻao ʻē aʻe, ʻaʻole pono nā paipu PPR i nā mea hoʻoheheʻe a hoʻopili ʻia e ka ʻenehana wela wela, no laila ʻaʻole lākou i loko o nā mea ʻona.

ʻO ka pipeline PPR ka pane olakino:
Hana ʻia nā paipu KPT PPR me nā mea waiwai kiʻekiʻe, ʻano meaʻai, ʻoluʻolu, ikaika, a hiki ke kū i kahi wela o -10 ° C a 95 ° C. He lōʻihi loa ke ola lawelawe ʻana o nā paipu KPT PPR, hiki ke hoʻohana ʻia ma mua o 50 mau makahiki.
