Cov khoom siv ntawm yas zaj duab xis tshuab tshuab:
(1) HDPE Fold
High Density Polyethylene (HDPE luv luv) yog ib hom thermoplastic resin nrog siab crystallinity thiab tsis polarity.Cov tsos ntawm thawj HDPE yog milky dawb, thiab lub micro blog seem yog translucent mus rau ib qho twg.PE muaj kev tiv thaiv zoo rau feem ntau hauv tsev. thiab muaj chemicals. Tej yam tshuaj muaj peev xwm ua rau cov tshuaj corrosion, xws li corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylenes), thiab halogenated hydrocarbons (carbon tetrachloride). Cov polymer yog tsis hygroscopic thiab muaj dej vapor tsis kam, thiab tuaj yeem siv rau kev ntim khoom.HDPE muaj cov khoom siv hluav taws xob zoo, tshwj xeeb tshaj yog lub siab dielectric lub zog ntawm rwb thaiv tsev, ua rau nws zoo heev rau cov xov hlau thiab cables. Nruab nrab rau siab molecular hnyav qib muaj kev cuam tshuam zoo heev, txawm tias ntawm -40F qis kub.
(2) LDPE Fold
Tsawg ntom polyethylene (LDPE) yog ib yam khoom yas, uas yog tsim rau ntau yam molding txheej txheem ntawm thermoplastic molding.and muaj zoo molding txheej txheem. , tshuab moulding hollow molding khoom, thiab lwm yam.
(3) LLDPE Fold
Linear low-density polyethylene yog qhov sib txawv ntawm cov qauv uas tsis tshua muaj ntom ntom polythylene hauv cov qauv vim tias tsis muaj cov saw ntev ntev.The linearity ntawm LLDPE nyob ntawm qhov sib txawv ntau lawm thiab kev ua cov txheej txheem ntawm LLDPE thiab LDPE.LLDPE feem ntau yog tsim los ntawm copolymerization ntawm ethylene thiab siab heev. -olefins xws li diene, ethylene los yog octene ntawm qhov kub thiab txias.LLDPE polymer tsim thaum lub sij hawm copolymerization tau nqaim molecular hnyav dua li LDPE zoo tib yam, thiab muaj qhov sib txawv rheological zog vim tis linear qauv.
