Cufnaanta Sare ee Beebka Polyethylene
Heerka tuubada HDPE waxay leedahay qaybin ballaaran ama laba-geesoodka miisaanka kelli.Waxay leedahay iska caabin gurguurta oo xoog leh iyo dheelitirnaan wanaagsan oo qallafsanaan iyo adayg.Aad bay u raagaysaa waxayna leedahay sag hoose marka la farsamaynayo.Tuubooyinka la soo saaray iyadoo la isticmaalayo xabagtani waxay leeyihiin xoog wanaagsan, adkeyd iyo iska caabin saameyn leh iyo hanti aad u wanaagsan oo SCG iyo RCP ah.
Xabagta waa in lagu kaydiyaa bakhaar qabyo ah, qalalan kana fog dabka iyo iftiinka qorraxda tooska ah.Waa in aan lagu soo ururin hawada furan.Inta lagu jiro gaadiidka, maaddadu waa in aan la soo gaadhin iftiinka qoraxda ama roobka, waana in aan lagu wada qaadin ciid, carro, biro qashinka ah, dhuxusha ama muraayadaha.Gaadiidka ay wataan sunta, daxalka iyo walaxda gubanaysa waa mamnuuc.
Codsiga
Heerka tuubooyinka HDPE waxaa loo isticmaali karaa soo saarista tuubooyinka cadaadiska, sida tuubooyinka biyaha la cadaadiyo, dhuumaha gaasta shidaalka iyo tuubooyinka kale ee warshadaha.Waxa kale oo loo isticmaali karaa samaynta tuubooyinka aan cadaadisku saarnayn sida tuubooyinka jiingadaha ah ee labajibbaaran, tuubooyinka dabaysha gidaarada godan, tuubooyinka silikoon-core, tuubooyinka waraabka beeraha iyo tuubooyinka isku xidha aluminium balaastikada.Intaa waxaa dheer, iyada oo loo marayo extrusion falcelineed (silane cross-linking), waxaa loo isticmaali karaa soo saarida tuubooyinka polyetylenka ee isku xiran (PEX) si loo siiyo biyo qabow iyo kulul.
