HDPE tseem hu ua high density polyethylene khoom.Nws yog ib hom thermoplastic resin nrog siab crystallinity thiab tsis polarity.Cov tsos ntawm thawj HDPE yog milky dawb thiab translucent rau qee yam hauv ntu nyias.Lub polymer tsis yog hygroscopic thiab muaj dej vapor tsis kam, uas tuaj yeem siv rau lub hom phiaj ntim.HDPE muaj cov khoom siv hluav taws xob zoo, tshwj xeeb tshaj yog lub zog dielectric siab ntawm rwb thaiv tsev, uas ua rau nws tsim nyog rau cov xov hlau thiab cables.Cov qib nruab nrab mus rau qib siab molecular muaj kev cuam tshuam zoo heev ntawm chav tsev kub lossis txawm tias -40f qis kub.HDPE feem ntau yog siv los uacev fitting, zoo li ib txhiakhoom ua si fittings, PK plug , audio.
Vim muaj zog sib txawv, cov kav dej HDPE yuav tsum muaj qee qhov siab.Feem ntau, PE resins nrog qhov hnyav molecular thiab cov khoom siv zoo, xws li HDPE resins, yuav tsum tau xaiv.Lub zog yog 9 npaug ntawm cov yeeb nkab zoo tib yam polyethylene (PE yeeb nkab).
Qhov hnav tsis kam yog txawv.Ntawm tag nrho cov yas engineering, HDPE muaj qhov hnav tsis kam zoo tshaj plaws.Qhov siab dua qhov hnyav molecular, cov khoom hnav-tiv taus ntau dua, thiab ntau dua li cov ntaub ntawv hlau (xws li carbon steel, stainless hlau, bronze, thiab lwm yam), PE zoo tib yam tsuas yog ib feem kaum ntawm HDPE.
Cov kav dej HDPE muaj qhov sib txawv ntawm kev hloov pauv.Lawv yog cov khoom hloov ntawm cov kav dej ib txwm siv thiab cov kav dej polychloroprene.Txawm li cas los xij, PE polychloroprene tsuas yog siv tau los ua cov yeeb nkab sab nraud, thiab txawm tias cov kav dej tsis tshua muaj PE tsuas tuaj yeem siv rau dej.
Scope ntawm daim ntawv thov yog txawv.HDPE cov kav dejFeem ntau yog siv rau: dej system ntawm municipal engineering, sab hauv tsev dej system ntawm cov tsev, sab nraum zoov faus dej system thiab faus dej system ntawm cov tsev nyob thiab cov chaw cog, qub pipeline kho, dej kho engineering pipeline system, industrial dej kav nyob rau hauv vaj, irrigation thiab lwm yam teb.Qhov nruab nrab ntom ntom PE kav tsuas yog tsim rau thauj cov pa roj carbon monoxide, cov pa roj ntsha thiab cov roj liquefied roj av.Tsawg ntom ntom PE kav yog hoses.
