Dhuumaha adag ee polyvinyl chloride (UPVC)
Dunida, dhuumaha adag ee polyvinyl chloride (UPVC) waa isticmaalka ugu badan ee dhammaan noocyada dhuumaha caagga ah, sidoo kale waa qalab cusub oo kiimiko ah oo lagu dhisayo gudaha iyo dibaddaba.Isticmaalka tuubooyinka noocaan ah ayaa door wanaagsan ka ciyaari kara yareynta xaaladda birta yaraanta iyo yaraanta tamarta, faa'iidada dhaqaalena waa mid cajiib ah.
Tuubada UPVC waxay leedahay sifooyinka soo socda:
1, daxalka kiimikada wanaagsan, aan miridhku lahayn;
2, oo leh is-deminta iyo ololka;
3, iska caabin gabow wanaagsan, waxaa loo isticmaali karaa inta u dhaxaysa -15 ℃ iyo 60 ℃ 20-50 sano;
4, derbiga gudaha waa siman yahay, xiisadda dusha derbiga gudaha, way adag tahay in la sameeyo miisaanka, awoodda gaadiidka dareere ka badan tuubada birta tuuray 43.7%;
5, tayada iftiinka, fududahay in la iftiimiyo, isku-xidhka, foorarsiga, alxanka, rakibidda shaqada waa 1/2 oo kaliya ee tuubada birta, xoogga shaqada oo hooseeya, muddada dhismaha gaaban;
6, waxqabadka iska caabin wanaagsan, caabbinta mugga 1-3 × 105ω.Cm, korantada burburka 23-2kV / mm;
7. Qiimaha hooseeya;
8, badbaadi tamarta birta;
9, adkaanta tuubada UPVC waa mid hooseeya, isugeynta fidinta tooska ah waa weyn, isticmaalka heerkul cidhiidhi ah.
Tuubbada chloride polyvinyl adag (UPVC) codsiyada ugu muhiimsan:
1. Dhismaha biyaha iyo nidaamka dhuumaha qulqulka;
2. Dhismaha nidaamka biyaha roobka;
3. Dhuumaha dhismaha fiilooyinka korantada;
4, hawo qaboojiyaha nidaamka kondensate
