Polythene yog ib qho ntawm cov yas nrov tshaj plaws hauv ntiaj teb. Nws yog ntau yam polymer uas haum rau ntau yam kev siv, los ntawm cov dej num hnyav hnyav rau cov yeeb yaj kiab rau kev tsim kho tshiab rau lub teeb yuag, hloov pauv lub hnab thiab cov yeeb yaj kiab.

Ob hom tseem ceeb ntawm PE yog siv rau hauv cov yeeb yaj kiab thiab cov khoom ntim tau yooj yim - LDPE (tsis tshua muaj ntom ntom), feem ntau yog siv rau cov pallets thiab cov yeeb yaj kiab hnyav xws li cov hnab ntim khoom ntev thiab cov hnab ntim khoom, polyethylene tunnels, cov yeeb yaj kiab tiv thaiv, hnab ntim khoom noj, thiab lwm yam.HDPE (siab ceev), Rau feem ntau nyias-gauge totes, cov khoom tshiab lub hnab, thiab ib co fwj thiab kaus mom.

Muaj lwm qhov sib txawv ntawm ob hom tseem ceeb no. Tag nrho cov khoom muaj vapor zoo los yog noo noo barrier zog thiab yog chemically inert.

Los ntawm kev hloov polyethylene formulations thiab specifications, producers/processors tuaj yeem kho qhov cuam tshuam thiab tsim kua muag; clarity thiab xav; yooj, formability, thiab txheej / laminating / luam ntawv muaj peev xwm. PE tuaj yeem rov ua dua tshiab, thiab ntau lub hnab khib nyiab, cov yeeb yaj kiab ua liaj ua teb, thiab cov khoom siv lub neej ntev xws li cov chaw ua si, bollards, thiab cov thawv khib nyiab siv cov khoom siv polyethylene. Vim nws cov nqi calorific siab,PE muabzoo heev zog rov qab los ntawm huv incineration.

Lub vaj ntim khoom ua los ntawm high-density polyethylene. Tus nqi qis, siab rigidity thiab yooj yim ntawm tshuab moulding ua cov khoom no yog ib qho kev xaiv ntuj rau vaj rooj tog.

HDPE lub raj mis yas
High-density polyethylene (HDPE) lub raj mis yas yog ib qho kev xaiv ntim rau cov mis nyuj thiab kua txiv hmab txiv ntoo tshiab. Hauv tebchaws Askiv, piv txwv li, nyob ib ncig ntawm 4 billion HDPE lub raj mis pub mis yog tsim thiab yuav txhua xyoo.

HDPE muaj ntau yam txiaj ntsig rau cov tuam txhab, cov khw muag khoom thiab cov neeg siv khoom.

Qhov zoo ntawm HDPE fwj
Recyclable: HDPE fwj yog 100% recyclable, yog li cov khoom siv tau rov qab siv dua

Sustainable: HDPE muab lub sijhawm los muab cov khoom siv rov ua dua tshiab rau hauv cov khoom siv

Ib qho yooj yim Lightweighting: HDPE Lub raj mis muab cov cib fim tseem ceeb

Kev hloov tau yooj yim: tsuas yog lub raj mis yas uas tuaj yeem siv los ua cov kua mis pasteurized monolayer, lossis ua UHT lossis cov kua mis tsis muaj menyuam co-extruded lub raj mis

Kev siv yooj yim: Tib hom ntim uas tso cai rau kev sib koom ua ke thiab ncuav qhov rau kev tswj tuav thiab nchuav

Muaj kev nyab xeeb thiab ruaj ntseg: Lub pob tsuas yog hom uas tuaj yeem muaj cov ntaub ntawv pov thawj sab nraud lossis cov khoom siv hluav taws xob induction kom tiv thaiv kom tsis txhob xau, khaws cov khoom tshiab, thiab qhia cov pov thawj ntawm tampering

Kev lag luam: HDPE fwj muaj ntau yam kev lag luam, xws li luam ntawv ncaj qha rau ntawm cov khoom, luam ntawv ncaj qha rau ntawm lub tes tsho lossis daim ntawv lo, thiab muaj peev xwm hloov kho cov duab kom nws sawv ntsug ntawm lub txee.

Innovation: Lub peev xwm los thawb ciam teb thiab ua tiav qhov tseem ceeb tshiab los ntawm kev siv tshuab tshuab moulding.

ib puag ncig qhov tseeb
HDPE cov me nyuam lub raj mis yog ib qho ntawm cov khoom ntim khoom siv dav hauv UK, nrog cov ntaub ntawv los ntawm Recoup qhia tias nyob ib ncig ntawm 79% ntawm HDPE cov me nyuam lub raj mis tau siv dua.
Qhov nruab nrab,HDPE fwjHauv UK tam sim no 15% sib zog dua li peb xyoos dhau los

Txawm li cas los xij, cov qauv tsim tshiab xws li qhov khoom plig Infini lub raj mis txhais tau tias tam sim no tuaj yeem txo qhov hnyav ntawm cov fwj txheem los ntawm 25% (nyob ntawm seb qhov loj me)

Qhov nruab nrab, HDPE fwj hauv UK muaj txog li 15% cov khoom siv rov ua dua tshiab

Txawm li cas los xij, kev nce qib hauv kev siv thev naus laus zis thiab kev tsim qauv tshiab ntawm cov khoom txhais tau tias kev ua tiav tshiab tau dhau los ua tau. Piv txwv li, xyoo 2013, Nampak tau ntxiv 30 feem pua ​​​​rov siv HDPE rau nws lub raj mis Infini, lub ntiaj teb ua ntej-ob xyoos ua ntej lub hom phiaj kev lag luam.
