Mbere yo kwinjira mubisobanuro, reka tubanze tumenye icyo buri kintu cyakozwe. PPR ni impfunyapfunyo ya polypropilene idasanzwe ya cololymer, mugihe CPVC ni chlorine polyvinyl chloride ikorwa binyuze muburyo bwa chlorine kugeza kuri chloride polyvinyl.
PPR ni uburyo bukoreshwa cyane mu miyoboro i Burayi, Uburusiya, Amerika y'Epfo, Afurika, Aziya y'Epfo, Ubushinwa n'Uburasirazuba bwo hagati, mu giheCPVCikoreshwa cyane mu Buhinde na Mexico. PPR iruta CPVC ntabwo ari ukubera kwakirwa kwayo, kandi ni umutekano wamazi yo kunywa.
Noneho, reka tugufashe gufata umwanzuro utekanye, wumve impamvu imiyoboro ya CPVC idafite umutekano nimpamvu ugomba guhitamoUmuyoboro wa PPR.

Ibiribwa bya plastiki:
Imiyoboro ya PPR ntabwo ikubiyemo ibikomoka kuri chlorine kandi ifite umutekano ku mubiri w'umuntu, mu gihe imiterere y'umuyoboro wa CPVC irimo chlorine, ishobora gutandukanywa no gushonga mu mazi mu buryo bwa vinyl chloride kandi ikegeranya mu mubiri w'umuntu.
Rimwe na rimwe wasangaga imyanda yabonetse mu bijyanye n'imiyoboro ya CPVC kubera ko ifata neza kandi igasaba imiti ikomoka ku miti, mu gihe imiyoboro ya PPR ihujwe no guhuza ubushyuhe kandi ikarinda imiyoboro minini kandi ikomera cyane. Imbaraga zishyizwe hamwe ziganisha ku bwoko ubwo aribwo bwose. Amerika yakoze ubushakashatsi bwinshi ku bijyanye no kwangiza ibintu bishobora guteza akaga nka chloroform, tetrahydrofuran na acetate mu mazi yo kunywa binyuzeImiyoboro ya CPVC.

Umuti ukoreshwa muri CPVC ushyira ubuzima bwawe mukaga:

Komisiyo ishinzwe ubucuruzi bw’imiyoboro ya Californiya ishinzwe gusuzuma ingaruka z’ubuzima bwa sisitemu kandi ni ikigo gishinzwe gutanga amashanyarazi muri Californiya, muri Amerika. Iteka ryashyigikiye cyane ingaruka mbi zumuti ukoreshwa muguhuza imiyoboro ya CPVC. Byagaragaye ko umusemburo urimo ibintu bitera kanseri mu nyamaswa kandi bifatwa nkaho bishobora kugirira nabi abantu. Ku rundi ruhande, imiyoboro ya PPR ntisaba umusemburo uwo ari wo wose kandi ihujwe n’ikoranabuhanga rishyushye, bityo ntiririmo imiti y’ubumara.

Umuyoboro wa PPR ni igisubizo cyiza:
Imiyoboro ya KPT PPR ikozwe mubikoresho byiza byo mu rwego rwo hejuru, ibiryo-by-ibiribwa, byoroshye, bikomeye, kandi birashobora kwihanganira ubushyuhe buri hagati ya -10 ° C na 95 ° C. Imiyoboro ya KPT PPR ifite ubuzima burebure cyane, bushobora gukoreshwa mumyaka irenga 50.
