1) Umbhobho wePVC kunye nesingeniso esifanelekileyo

Iimbonakalo
Non-toxic: akukho izongezo zentsimbi enzima
Ukumelana nokuMhlwa: ukuxhathisa imiba yeekhemikhali, ukubola kweekhemikhali ze-electron okanye ukurusa
Iindleko zokuFakelo eziphantsi: ubunzima obulula kunye nokulula kofakelo
Iindonga zangaphakathi ezigudileyo: ukukhuhlana okuphantsi kunye nomthamo ophezulu kunemibhobho yentsimbi
Ubomi obude: ngaphezu kweminyaka engama-50 phantsi kweemeko eziqhelekileyo
Irisayikilishe kwaye ilungele imeko-bume

Usetyenziso
umhlaba kunye nemibhobho yokulahla inkunkuma ngaphakathi kwesakhiwo
imibhobho yamanzi emvula ngaphakathi kwisakhiwo
imibhobho yokuhambisa amanzi engcwatywe ngaphandle koxinzelelo emhlabeni

2) Umbhobho wePVC kunye neenzuzo ezifanelekileyo

1.Ubunzima bokukhanya: ubunzima kubude beyunithi yi-1/6 kuphela yemibhobho yentsimbi.
2.Amandla aphezulu: amandla okuqina afika ngaphezulu kwemephu engama-45.
3.Ukuchasana okuphantsi: udonga lwangaphakathi lugudile kwaye luthintela ukwakhiwa kwe-scum.Uxinzelelo lwamanzi kunye nokukhutshwa kombhobho we-PVC-U yi-30% ephantsi kunemibhobho yentsimbi etyhidiweyo enobubanzi obufanayo kwaye inokugcina iindleko zokukhutshwa kwamandla.
I-4.I-Corrosion resistance: ukuchasana okugqwesileyo kwi-corrosion ebangelwa i-acids, i-alkaline, iikhemikhali kunye nombane, ngoko ke ungabangeli amabala.
Ukufakwa kwe-5.Easy: idibanisa lula ngamakhonkco e-rubber.Kulula ukuyifaka kwaye itywine kakuhle.
I-6.Ubomi obude: phantsi kweemeko eziqhelekileyo ubomi bunokufikelela kwiminyaka eyi-50.
I-7.Ixabiso eliphantsi: ngexabiso eliphantsi lofakelo.Ukuthuthwa kunye nezinto eziluhlaza, iindleko ezipheleleyo zobunjineli zenza i-PVC-U i-30% ephantsi kunemibhobho yentsimbi.
