I-Polyethylene Vapor Barrier
Incazelo Yomkhiqizo
Inkampani yethu, iShanghai Yingfan Engineering Material Co., ingelinye labakhiqizi abahamba phambili be-polyethylene water vapor barrier eChina. Sihlinzeka ngepulasitiki ye-polyethylene vapor barrier ngaphansi kwe-slab kakhonkolo noma ngemuva kwebhodi likasimende noma izindonga ezingaphansi noma ezingaphansi. I-6mil/9mil/10mil/20mil/ezinye izithiyo zomhwamuko we-polyethylene eziwugqinsi ziyatholakala kokunikezwa kwethu.

I-Polyethylene vapor Barrier Isingeniso (ecashunwe ku-wiki)
Umgoqo womhwamuko (noma umgoqo womhwamuko) yinoma iyiphi into esetshenziselwa ukuvikela umswakama, ngokuvamile ipulasitiki noma ishidi le-foil, elimelana nokusatshalaliswa komswakama odongeni, phansi, ophahleni, noma ekuhlanganiseni kophahla lwezakhiwo ukuvimbela ukuminyana nokupakishwa. Ngobuchwepheshe, eziningi zalezi zinto ziwukubuyisela emuva umhwamuko kuphela njengoba zinamazinga ahlukahlukene okungena.
Izinto zokwakha zinezinga lokudlulisa umhwamuko (MVTR) elisungulwa ngezindlela zokuhlola ezijwayelekile. Isethi eyodwa evamile yamayunithi i-g/m²·day noma i-g/100in²·day. Ukungena kungabikwa kumaphemu, isilinganiso sezinga lokudluliselwa komhwamuko wamanzi ngento (1.0 US perm = 1.0 uhlamvu/square-foot·hour·inch of mercury ≈ 57 SI perm = 57 ng/s·m2·Pa ). Amakhodi okwakha aseMelika ahlukanise izinqamuleli zomhwamuko njengezinomswakama wamanzi onyakazayo ongu-1 perm noma ngaphansi uma zihlolwa ngokuvumelana ne-ASTM E96 desiccant, noma indlela yenkomishi eyomile.[1] Izinto ezibuyisela umusi ngokuvamile zihlukaniswa ngalezi:
Okungangenisi (≤1 US perm, noma ≤57 SI perm) - njengephepha le-kraft eline-asphalt, i-elastomeric coating, upende obuyisela umhwamuko, upende osuselwe kuwoyela, izindonga ze-vinyl, i-polystyrene ekhishiwe, i-plywood, i-OSB;
I-Semi-permeable (i-1-10 US perm, noma i-57-570 SI perm) - njenge-polystyrene enganwetshiwe, i-fiber-faced isocyanurate, amaphepha okwakha asindayo afakwe i-asphalt, amanye amapende asekelwe ku-latex);
Okuvunyelekayo (>10 US perm, noma >570 SI perm) – njengebhodi legypsum elingapendiwe kanye nokhonkolo, ukugqunywa kwengilazi yefayibha engafakwanga ubuso, ukugqunywa kwe-cellulose, isituko esingapendiwe, amashehethi asimende, i-pololefin ephothiwe noma amanye amafilimu angaphandle asuselwa ku-polymer.
Isithiyo se-Polyethylene vapor: Isithiyo se-polyethylene vapor esiminyana kakhulu
Singumkhiqizi owaziwayo we-high density polyethylene water vapor barrier e-China. Ukungena komkhiqizo wethu kungaphansi kuka-≤1.0×10-13 g•cm(cm2)•pa. Ngakho-ke ingahlukaniswa njengesithiyo somhwamuko esingangenisi. Impilo yayo ingahlala iminyaka engaphezu kwengama-70 kulolu hlelo lokusebenza. Ububanzi bungafinyelela ngaphezu kuka-8m kanti ubude bungafinyelela ngaphezu kwama-800m.

Ukuqinisekisa umswakama kuyingxenye ebaluleke kakhulu yokugcina isakhiwo sesakhiwo sizinzile lapho uklama ukwakhiwa. Impahla yethu eguquguqukayo nenhle engangenisi yomkhawulo wethu womswakama we-polyethylene ifakazelwe kumaphrojekthi amaningi okuvimbela umusi wephansi nezindonga ngokuphindaphindiwe.
Ngentengo yokuvimbela umhwamuko we-polyethylene, ungaluleka ukuthengisa kwethu ngokuya ngethuluzi lethu lengxoxo eliku-inthanethi noma omunye othintana naye.
