Nguwuphi umahluko phakathi kwe-PVC kunye nophahla lwe-vvc?
Xa ukhetha izixhobo zophahla, i-PVC (i-PVC (i-Polyvinyl Chloride) kunye ne-UVV zizinto ezimbini ezithandwayo. Ngamnye unepropathi eyahlukileyo efanelekileyo kwiimfuno ezahlukeneyo zokwakha. Ukuqonda ukungafani kwabo kunokubanceda abanini bamakhaya, iikhontraktha, kwaye abasasazi benze izigqibo ezinolwazi.
Uphahla lwe-pvc
Zongezwa iiplastiki zokuphucula ukukhululeka kokubumba kunye nokuguquguquka kancinci ngexesha lemveliso. Aba baphangisi bavumela iithayile ukuze zihambelane ngokulula kophahla olugobileyo ngexesha lokufakwa. I-PVC ikwabonelela ngokuchasene namanzi agqwesileyo, ukumelana nokucoca, kunye nokunganyangeki kwemozulu, ukwenza ukuba isetyenziswe ngokubanzi kwizakhiwo zeshishini, ezorhwebo, nezolimo. Ukukhanya kwendalo ngokwemvelo kunciphisa imithwalo yesakhiwo, kwaye umphezulu wayo ogudileyo unceda ukukhusela ukuqokelela ubumdaka kunye nokuzicoca iipropathi,- ukusebenza okungapheliyo.
Uphahla lwe-UPVC
I-UPVC yenziwe ngokupheleleyo ngaphandle kwephangiselwane, ukuthembela kuphela kwi-pvc resin ngokwayo kunye nokongezwa njengezilotha kunye ne-anti {0} {0} {0}- iiarhente zokuhlukumeza. Ulwakhiwo lwayo olunzima lwemveli lubonelela ngobuqili obukhulu kunye nokuxhathisa kungenelelo lwangaphandle, kwaye inika ukumelana ngomlilo. Uphahla lwe-UPVC lukwabonelela ngokufakelwa ngokugqibeleleyo kunye nokuncitshiswa kwengxolo, kwenza ukhetho olufanelekileyo lwezakhiwo zokuhlala, ezorhwebo kunye nezakhiwo zikarhulumente. I-ASA ye-ASA engaphezulu, okanye ukukhusela i-cow, iqinisekisa ukuba i-IVVC igcina uzinzo lwemibala phantsi kwe-UV ekuvezweni kwe-UV, ukuqinisekisa ukuba uphahla aluyi kuphelelwa amashumi eminyaka.
Umahluko ophambili phakathi kweethayile ze-pvc uphahla lweethayile ze-pustc uphahla ngokukuko "{0 {0} {{1} {{1} {{1} {{1} {{1} {{1} {{1}) Iithayile ze-PVC Redin zinenzuzo yexabiso lokuqala lendleko zokuqala kunye nokufakelwa okuguquguqukayo, zibenzela ukuba bazisebenzise okwethutyana. I-Underc Redin Iithayile, kwelinye icala, zizinto zokuqala zekota {{4}. Xa ukhetha uphahla lophahla, kufuneka uqwalasele iimfuno ezithile zeprojekthi kunye neemeko zokusingqongileyo ukukhetha uphahla olufanelekileyo olufanelekileyo ngokwenene.
