Dab tsi yog cov ntaub ntawv raw rau tshuab ua yeeb yaj kiab extrusion? Kawm paub txog polyethylene hom thiab siv

Blown zaj duab xis extrusion yog ib cov txheej txheem tsim khoom siv rau kev ua yeeb yaj kiab yas, uas yog cov khoom siv sib xyaw ua ke, thiab lwm yam khoom siv hluav taws xob tsis zoo, thiab cov khoom siv xav tau ntawm Polyethylene yog tsawg-ceev polyethylene (ldpe), High-ntom polyethylene (HDPE), thiab tawm ntawm cov khoom siv tsis muaj zog, thiab cov lldpe), thiab muaj zog, thiab meej}

Cov Ntsiab Lus Tseem Ceeb:
Dab tsi yog cov ntaub ntawv raw rau tshuab ua yeeb yaj kiab extrusion? Kawm paub txog polyethylene hom thiab siv
Cov Khoom Siv Raw: Polyethylene Polyethylene

Cov ntsiab lus thiab cov yam ntxwv: Polyethylene yog ib qho khoom siv thermoplastic tsim los ntawm ethylene tsis kam, thiab tom qab ntawd txias los ua yeeb yaj kiab .
Hom Polyethylene:
Tsawg-ceev polyethylene (LDPE): Qeeb qis polyethylene yog tus yam ntxwv uas yuav tsum muaj cov ntaub ntawv muag, xws li ntim cov hnab yas thiab ntim hnab.
High-ceev polyethylene (HDPE): HDPE yog Stiffer thiab muaj cov yeeb yaj kiab siab dua, xws li cov hnab ntim khoom khov kho thiab cov ntaub pua chaw muag khoom thiab kev lag luam.
Linear tsawg-ceev polyethylene (Lldpe): Lldpe ua ke ntawm kev siv HDPE nrog lub zog ntawm HDPE nrog lub hnab zaj duab xis thiab lub hnab ntim khoom hnyav thiab hnyav-}
Cov Khoom Siv Raw Cov Khoom Siv

Qhov kawg-siv cov kev xav tau: qhov kev xaiv ntawm cov polyethylene hom yog xav tau cov kev xav tau siab, thaum lub zog siab tau xaiv rau nws lub zog thiab rigidity {}}
Ua haujlwm: sib txawv hom polyethylene muaj cov ntsiab lus sib txawv thiab yog yooj yim rau cov txheej txheem, uas muaj haum rau kev ua kom siab-ceev extrusion.
Cov kev txiav txim siab them nqi: Cov khoom siv khoom siv tau tseem yog qhov tseem ceeb hauv cov txheej txheem xaiv ntau dua li cov duab uas yuav tsum muaj ntawm cov yeeb yaj kiab kawg ntawm cov yeeb yaj kiab kawg .
Lwm yam kev sib ntxiv thiab hloov kho

Stabilizers: ntxiv rau cov polymer kom tiv thaiv kev tsis sib haum thaum lub sijhawm tsis muaj zog pab tswj cov khoom ntawm cov yeeb yaj kiab .
Colorants: Colorants yog siv los ntxiv xim rau cov yeeb yaj kiab . Lawv tuaj yeem ntxiv rau cov pigments thiab ntxiv.
Cov neeg sawv cev tawm tsam: Cov tshuaj ntxiv no ntxiv los txo cov hluav taws xob zoo li qub nyob rau hauv cov ntawv qhia uas muaj teeb meem hauv hluav taws xob {}}
Cov neeg sawv cev los tiv thaiv cov neeg sawv cev: cov neeg sawv cev tsis huv tau siv los txo cov coefficient ntawm cov zaj duab xis nyob rau saum npoo ntawm zaj duab xis, ua rau nws yooj yim dua thiab cov txheej txheem.
Ib puag ncig thiab kev txiav txim siab ntev

Rov ua dua tshiab: polyethylene zaj duab xis yog rov ua dua tshiab, thiab muaj ntau cov tuam ntxhab tsom rau kev siv cov khoom siv ua rov qab los txo cov kev cuam tshuam hauv ib puag ncig .
Biodegradable additives: Qee cov tuam ntxhab Ntxiv rau biodegradable ntxiv rau polyethylene zaj duab xis los txhim kho cov zaj duab xis los sai dua hauv ib puag ncig.
Hauv cov ntsiab lus, cov ntaub ntawv raw rau Blown zaj duab xis ua rau muaj cov yeeb yaj kiab tshwj xeeb, thiab cov kev xav tau ntxiv los txhim kho cov yam ntxwv thiab kev ua tau zoo ntawm cov zaj duab xis . kev txiav txim siab ib puag ncig kuj tseem yuav ua tau ib qho tseem ceeb thaum xaiv cov yeeb yaj kiab rawces {}
