Umgca wokukhupha umbhobho we-PVC-UH/UPVC/CPVC

Umbhobho wePVC ngumbhobho weplastiki owenziwe ngezinto ze-thermoplastic polyvinyl chloride (PVC). Umbhobho wePVC usetyenziswa kakhulu kuzo zonke iinkqubo kunye namashishini kwaye uza kwiintlobo ezahlukeneyo. Imibhobho yePVC idla ngokusetyenziswa ekutsaleni amanzi, ukubonelela ngamanzi, ukunkcenkceshela, ukuphathwa kweekhemikhali, iityhubhu zomoya, umsebenzi wemibhobho kunye nolawulo lwenkunkuma. Iimveliso zokubonelela ngemibhobho zePVC ezikhoyo yishedyuli 40 yePVC, ishedyuli 80 yePVC, umbhobho wePVC wezinga lefenitshala, umbhobho weCPVC, umbhobho we-drain waste vent (DWV), umbhobho oguquguqukayo, umbhobho wePVC ocacileyo kunye nombhobho wokuqulatha kabini.

IShedyuli 40 kunye neShedyuli 80 ziipayipi eziguquguqukayo eziqinisekisiweyo kwaye zibhalisiwe ngokweekhowudi kunye nemigangatho yoshishino yanamhlanje yokusetyenziswa okuninzi. Ipayipi yePVC yenqanaba lefenitshala ifumaneka ngemibala eyahlukeneyo ngaphandle kweempawu okanye iilebhile kwaye inomphetho ococekileyo nocwebezelayo. Ipayipi ye-DWV isetyenziselwa ukuphatha izinto ezilahliweyo ngokwesakhiwo. Ipayipi eguquguqukayo yipayipi yePVC eguquguqukayo kwizicelo apho ipayipi eqinileyo ingafanelekanga okanye ingasebenzi. Ipayipi ecacileyo ivumela ukujonga ngokubonakalayo ukuhamba kolwelo kunye nomgangatho wepayipi. Ipayipi ephindwe kabini yenzelwe ukuhlangabezana nemigaqo yoshishino ukubamba ukuvuza okanye ukusilela kwenkqubo ukuphucula ukhuseleko okanye xa kufuneka.

Umbhobho wePVC ufumaneka ngobukhulu obuqala kwi-1/8 intshi ukuya kwi-24 intshi ububanzi. Ezinye zezona sayizi ziqhelekileyo yi-½ intshi, i-1 ½ intshi, i-3 intshi, i-4 intshi, i-6 intshi, i-8 intshi kunye ne-10 intshi yombhobho wePVC. Imibhobho yePVC ithunyelwa ngamacandelo aqhelekileyo angama-10 intshi okanye ubude beenyawo ezingama-20. Oku kusindisa iindleko zokuphatha kwaye kuvumela ukubonelela ngeemveliso ezixabiso liphantsi. Sinamacandelo angama-5 enyawo e-SCH 40 PVC, i-SCH 80 PVC kunye nefenitshala yePVC efumaneka kuphela kwindawo yokuthumela impahla.

Xa i-PVC isetyenziswa ukubhekisa kumbhobho weplastiki, idla ngokuqondwa njenge-uPVC (i-PVC engafakwanga iplastiki) ngokwendlela eyilwe ngayo. Umbhobho we-uPVC ngumbhobho weplastiki oqinileyo kwaye lolona hlobo luqhelekileyo lwemibhobho ye-PVC esetyenziswa kwizicelo zokwakha. Imibhobho ye-uPVC yenziwa ngaphandle kwee-arhente zeplastiki ezinokongezwa ukwenza izinto ze-PVC zibe bhetyebhetye ngakumbi. Umbhobho oguquguqukayo ngumzekelo we-PVC eyenziwe ngeplastiki ngenxa yokuguquguquka kwayo okufana nombhobho.
