Ukuzinza kwezinto phantsi koxinzelelo lwe-oxidative kunye nokusingqongileyo kuthetha ukuba i-Quick and Easy Fittings (PPSU Material) inokuhambisa ukusebenza okuthembekileyo kumashumi eminyaka, nakwiimeko ezinzima.
I-PPSU vs. Izinto zeMveli
I-PPSU ibonelela ngeenzuzo ezininzi ngaphezulu kwezixhobo zemveli ezinje ngobhedu kunye nobhedu. Ngelixa izixhobo zentsimbi zihlala zinengxaki yokubola, i-leaching leaching, kunye nokwakheka kwe-biofilm, i-PPSU ihlala ingasebenzi kwaye izinzile. Ezi ngongoma zilandelayo zibalaselisa umahluko ongundoqo:
- I-PPSU ayidli okanye ikhuphe izinto ezinobungozi emanzini, ixhasa imigangatho ephezulu yococeko.
- Izinto eziphathekayo zimelana nokuphindaphinda inzalo kunye nokuvezwa kwii-agent zokucoca, ngokungafaniyo nezinyithi ezinokuthi zithobe okanye zigobe ngokuhamba kwexesha.
- Ufakelo lwePPSU lugcina ingqibelelo yabo yomatshini kunye neempawu zomhlaba amashumi eminyaka, ukunciphisa imfuno yokutshintshwa rhoqo.
Iingcali ezikhetha i-PPSU zixhamla kwinkqubo yemibhobho ehlangabezana nokhuseleko lwangoku, ukuqina, kunye neemfuno zococeko. Ukufakwa ngokukhawuleza kunye nokuLula (i-PPSU Material) ibeka umgangatho omtsha wokuthembeka, ukunceda izibonelelo ezizayo-ubungqina beziseko zabo.
Ukufakela kunye neeNzuzo zeNdleko zoFakelo oluKhawulezayo kunye nokuLula (iMaterial yePPSU)
Inkqubo yoFakelo olulula
Abafakeli bayaxhamla ekuhambeni komsebenzi okukhawulezayo xa besebenzisaUFakelo oluKhawulezayo noLulula (i-PPSU Material). Ezi zinto zifakelweyo azidingi zixhobo zokudityaniswa, ukuthunga, okanye izixhobo ezinzima. Inkqubo yokuhlanganisa ayinazo zixhobo kwaye iyaqondakala, ivumela abasebenzi abanamava kangako ukuba bafezekise unxibelelwano oluthembekileyo. Ngokomzekelo, ukuqhutyelwa kombhobho weemitha ezili-10 kunokugqitywa kwimizuzu engama-30 kuphela kunye nezixhobo ze-PPSU, ngelixa umbhobho wobhedu uthatha malunga neyure. Le theyibhile ilandelayo ibalaselisa uthelekiso lwexesha lofakelo:
| Uhlobo lwezinto eziphathekayo | Ixesha lokuFakela xa lithelekiswa neNsimbi |
|---|---|
| I-PPSU PEX | 60% ngokukhawuleza |
| CPVC | 30% ngokukhawuleza |
| Intsimbi | Isiseko |
