Dab tsi ntawm yas yog PE?
PE (Polyethylene, Polyethylene) yog ib qho ntawm cov feem ntau thermoplastics siv hauv kev lag luam tshuaj. Nws yog dav siv nyob rau hauv ntau thaj teb thiab tau dhau los ua cov khoom siv ntawm kev xaiv hauv ntau qhov kev lag luam vim nws cov khoom siv lub cev thiab kev lag luam zoo heev. Hauv tsab xov xwm no, peb yuav txheeb xyuas cov hom PE plastics, lawv cov khoom thiab lawv cov ntawv thov tseem ceeb los pab koj kom nkag siab zoo dua cov khoom tseem ceeb no.
Cov Txheej Txheem Txheej Txheem Saib ntawm PE Plastics
PE yas yas (polyethylene) yog cov khoom siv polymer tsim los ntawm polymerisation ntawm ethylene monomer. Ua raws li ntawm lub siab thiab kub thaum lub zog polymerisation, cov kab ke tsis tshua muaj zog (LDPE) thiab linear qis polyethylene (LLDPE). Txhua hom PE yas tau muaj nws tus kheej xim thiab cov khoom rau cov ntawv thov sib txawv.
Hom PE plastics thiab lawv cov yam ntxwv
Tsawg qis ntom ntom polyethylene (ldpe)
LDPE yog tsim los ntawm cov kev siab siab polymerisation ntawm ethylene, uas muaj ntau yam kev ua kom zoo nkauj ntawm crystallinity. Yog li cov kev cuam tshuam, thiab feem ntau siv hauv kev tsim cov Films, hnab yas thiab ntim khoom noj. Txawm hais tias nws cov peev xwm tsawg thiab hardness, ldpe lub txheej txheem zoo thiab tus nqi qis ua rau nws tseem ceeb hauv cov ntaub ntawv ntim khoom.

Kev kub siab Polyethylene (HDPE)
HDPE yog polymerised nyob rau hauv cov qauv siab thiab muaj ntau txoj kev siv tshuaj ntsuab, ua rau muaj zog ntau ntxiv thiab tensile lub zog, thaum nws tseem muaj permeability ntau. Cov khoom siv HDPE dav hauv kev tsim cov kav dej, ntim, hwj, fwj thiab cov tshuaj tivthat tsis sib haum, ntawm lwm tus.

Linear tsawg ntom polyethylene (LLDPE)
LLDPE yog tsim los ntawm co-polymerising polyethylene nrog me me ntawm copolymer monomers (piv txwv li butene, Hexene) ntawm lub siab qis. Nws ua ke qhov yooj yim ntawm LDPE nrog lub zog ntawm HDPE, thaum ua yeeb yam zoo tshaj plaws los ua cov yeeb yaj kiab zoo, xws li cov yeeb yaj kiab ua liaj ua teb, thiab lwm yam.

Cov chaw thov tseem ceeb ntawm PE plastics
Vim muaj ntau yam thiab kev ua tau zoo ntawm PE plastics, nws cov ntawv thov yog dav heev. Hauv kev lag luam ntim khoom, PE plastics feem ntau siv los ua ntau hom yeeb yaj kiab yas, hnab thiab ntim ntim. Hauv kev sib txuas ntawm cov kav dej, HDPE feem ntau siv nyob rau hauv kev tsim cov dej ntawm cov dej thiab cov kav dej ntws tawm, roj av, thiab lwm yam. Hauv cov khoom hauv tsev, PE plastics yog dav siv los tsim fwj, ntim thiab lwm yam khoom yas. Nyob rau hauv teb ntawm kev ua liaj ua teb, Lldpe thiab LDPE yog dav siv los ua cov yeeb yaj kiab ua liaj ua teb kom muab cov duab cog qoob loo thiab npog av.
Mus rau constumize
Dab tsi yog PE yas? Nws yog ib qho ntau yam, kev lag luam thiab dav siv thermoplastic. Los ntawm kev nkag siab txog ntau hom PE yas yas thiab lawv cov khoom, kev lag luam thiab cov neeg siv khoom tuaj yeem xaiv cov khoom zoo rau lawv cov kev xav tau. Los ntawm ntim thiab tubing rau cov khoom lag luam hauv tsev, PE yas ua si yog lub luag haujlwm tseem ceeb hauv lub neej niaj hnub nrog nws cov txiaj ntsig tshwj xeeb. Yog tias koj tsis meej pem thaum xaiv cov ntaub ntawv yas, peb vam tias tsab xov xwm no tuaj yeem muab cov ntaub ntawv tseem ceeb rau koj.
