Ngaphambi kokungena kwi-specification, masiqale siqonde ukuba yintoni na into nganye eyenziwe ngayo.I-PPR sisishunqulelo se-polypropylene random copolymer, ngelixa i-CPVC ine-chlorine ye-polyvinyl chloride eveliswa ngenkqubo ye-chlorination kwi-polyvinyl chloride.
I-PPR yeyona nkqubo isetyenziswa kakhulu kwimibhobho eYurophu, eRashiya, eMzantsi Melika, eAfrika, eMzantsi Asia, eChina nakuMbindi Mpuma, ngelixaCPVCisetyenziswa ikakhulu eIndiya naseMexico.I-PPR ingcono kune-CPVC kungekhona ngenxa yokwamkelwa kwayo ngokubanzi, kwaye ikhuselekile kumanzi okusela.
Ngoku, makhe sikuncede wenze isigqibo esikhuselekileyo, uqonde ukuba kutheni imibhobho yeCPVC ingakhuselekanga kwaye kutheni kufuneka ukhethePPR imibhobho.

Iplastiki yebakala lokutya:
Imibhobho ye-PPR ayinayo i-chlorine derivatives kwaye ikhuselekile kumzimba womntu, ngelixa isakhiwo sepayipi ye-CPVC siqukethe i-chlorine, enokuthi ihlulwe kwaye ichithwe emanzini ngendlela ye-vinyl chloride kwaye iqokelele emzimbeni womntu.
Kwezinye iimeko, i-leaching ifunyenwe kwimibhobho ye-CPVC ngenxa yokuba i-adhesion ebuthakathaka kwaye ifuna i-solvents yeekhemikhali, ngelixa iipayipi ze-PPR zidibene kunye nokudibanisa ukushisa kunye nokuthintela imibhobho enzima kunye nokubambelela okunamandla.Amandla adibeneyo akhokelela kulo naluphi na uhlobo lokuvuza.I-United States iqhube izifundo ezininzi malunga ne-leaching yezinto ezinobungozi ezifana ne-chloroform, i-tetrahydrofuran kunye ne-acetate emanzini okusela ngokusebenzisa.Imibhobho yeCPVC.

Izinyibilikisi ezisetyenziswa kwi-CPVC zibeka impilo yakho emngciphekweni:

IKomishoni yoRhwebo ngemibhobho yaseCalifornia inoxanduva lokuphonononga iziphumo zempilo zeenkqubo zemibhobho kwaye iyi-arhente yezatifikethi zemibhobho yamanzi eCalifornia, eMelika.Isoloko ikhuthaza kakhulu imiphumo eyingozi ye-solvents esetyenziselwa ukudibanisa imibhobho ye-CPVC.Kufunyenwe ukuba i-solvent iqulethe izinto ze-carcinogenic kwizilwanyana kwaye ithathwa njengento enobungozi ebantwini.Ngakolunye uhlangothi, iipayipi zePPR azifuni naziphi na i-solvents kwaye zixhunywe ngeteknoloji ye-hot-melt, ngoko ayinayo imichiza enobuthi.

Umbhobho wePPR yimpendulo enempilo:
Imibhobho ye-KPT PPR yenziwe ngemathiriyeli ekrwada ekumgangatho ophezulu, ibakala lokutya, ibhetyebhetye, inamandla, kwaye inokumelana noluhlu lobushushu obuphakathi kwe -10°C ukuya kuma-95°C.Imibhobho ye-KPT PPR inobomi benkonzo obude kakhulu, enokusetyenziswa ngaphezu kweminyaka engama-50.
