Inzitizi ya Polyethylene
Ibisobanuro ku bicuruzwa
Isosiyete yacu, Shanghai Yingfan Engineering Material Co., ni umwe mu bakora inganda zangiza imyuka ya polyethylene mu Bushinwa. Dutanga inzitizi ya parasitike ya polyethylene isukuye munsi ya plaque ya beto cyangwa inyuma ya sima cyangwa kurukuta cyangwa hasi. 6mil / 9mil / 10mil / 20mil / izindi mil zibyibushye za polyethylene zumuyaga ziraboneka mubyo dutanga.
Inzitizi 10 mil polyethylene
20 mil polyethylene imyuka ya barrière
inkumi ya polyethylene inzitizi
Inzitizi ya polyethylene Intangiriro Intangiriro (yavuzwe kuri wiki)
Inzitizi y'umwuka (cyangwa inzitizi zumuyaga) ni ibikoresho byose bikoreshwa mukugaragaza neza, ubusanzwe urupapuro rwa plastiki cyangwa fayili, rwanga ikwirakwizwa ryamazi binyuze murukuta, hasi, igisenge, cyangwa igisenge cyamazu yinyubako kugirango birinde guhuza hamwe no gupakira. Muburyo bwa tekiniki, ibyinshi muribi bikoresho ni ibyuka byuka gusa kuko bifite impamyabumenyi zitandukanye.
Ibikoresho bifite igipimo cyogukwirakwiza imyuka (MVTR) gishyirwaho nuburyo busanzwe bwo gupima. Igice kimwe gisanzwe ni g / m² · umunsi cyangwa g / 100in² · umunsi. Uruhushya rushobora kumenyeshwa muri perms, igipimo cyikigereranyo cyikwirakwizwa ryumwuka wamazi ukoresheje ibikoresho (1.0 US perm = 1.0 ingano / kare-metero · isaha · santimetero ya mercure ≈ 57 SI perm = 57 ng / s · m2 · Pa ). Amategeko y’inyubako y’Abanyamerika yashyize mu majwi abadindiza imyuka nk’uko bafite imyuka y’amazi ya permis 1 cyangwa irenga iyo igeragejwe hakurikijwe desiccant ya ASTM E96, cyangwa uburyo bwumye bwumye. [1] Ibikoresho bigabanya imyuka muri rusange byashyizwe mu byiciro nka:
Ntibishoboka (≤1 Uruhushya rwo muri Amerika, cyangwa ≤57 SI perm) - nk'impapuro zashigikiwe na asifalt, impapuro za elastomeric, irangi ryangiza, irangi rishingiye ku mavuta, amarangi y’urukuta rwa vinyl, polystirene yasohotse, pani, OSB;
Semi-permeable (1-10 uruhushya rwo muri Amerika, cyangwa 57-570 SI perm) - nka polystirene yagutse idahinduwe, isocyanurate ya fibre-fibre, impapuro zubaka zatewe na asfalt ziremereye, amarangi ashingiye kuri latex);
Byemewe (> 10 uruhushya rwo muri Amerika, cyangwa> 570 SI uruhushya) - nk'ibibaho bya gypsumu bidafite irangi na plaster, insimburangingo ya fibre idafite ibirahure, insuline ya selile, stucco idasize irangi, shement shement, polyolefin cyangwa filime zimwe na zimwe zishingiye kuri polymer.
Inzitizi ya polyethylene: Inzitizi nyinshi ya polyethylene
Turi abantu bazwi cyane bakora uruganda rwinshi rwa polyethylene rwamazi yo mu Bushinwa. Ibicuruzwa byacu byinjira munsi ya ≤1.0 × 10-13 g • cm (cm2) • pa. Irashobora rero gushyirwa mubyiciro nkinzitizi zumuyaga. Igihe cyacyo gishobora kumara imyaka irenga 70 muriki gikorwa. Ubugari bushobora kugera kuri 8m kandi uburebure bushobora kugera kuri 800m.

Kugaragaza neza ni igice cyingenzi cyane kugirango imiterere yinyubako itajegajega mugihe cyo gutegura inyubako. Ibintu byoroshye kandi byiza bidashobora kwangirika kuri barrière yubushyuhe bwa polyethylene byagaragaye mumishinga myinshi ya barrière barrière hasi no kurukuta.
Kubiciro bya barrière ya polyethylene, urashobora gutanga inama yo kugurisha ukurikije igikoresho cyo kuganira kumurongo cyangwa ubundi buryo bwo guhuza.
