Dab tsi ntawm cov yas yog PE? Kev piav qhia ntxaws txog hom, cov khoom thiab kev siv ntawm polyethylene (PE)
PE yas yog dab tsi?
"PE yas yog dab tsi?" Lo lus nug no feem ntau nug, tshwj xeeb tshaj yog nyob rau hauv cov tshuaj thiab manufacturing industries.PE, los yog polyethylene, yog ib tug thermoplastic ua los ntawm polymerising ethylene monomer. Raws li ib qho ntawm cov khoom siv ntau tshaj plaws, PE paub txog nws txoj kev siv ntau yam thiab ntau yam kev siv. Nws cov nqi qis, siab plasticity thiab tshuaj lom neeg ruaj khov ua rau nws yog ib qho khoom siv tseem ceeb hauv kev lag luam niaj hnub no.
Hom PE Plastics
Polyethylene (PE) yas muab faib ua peb pawg tseem ceeb: low-density polyethylene (LDPE), high-density polyethylene (HDPE) thiab linear low-density polyethylene (LLDPE).
Tsawg Density Polyethylene (LDPE)
LDPE yog ib qho polyethylene nrog cov qauv dispersed ntau dua, ua rau qis dua. Nws yog yoog raws thiab pob tshab thiab feem ntau siv hauv kev tsim cov hnab yas, cling zaj duab xis thiab cov ntaub ntawv ntim khoom yooj yim.

High Density Polyethylene (HDPE)
HDPE muaj cov qauv siv hluav taws xob nruj dua li LDPE, ua rau muaj cov khoom siv roj ntau dua nyob rau hauv kev tsim khoom siv txhua hnub, xws li cov mis nyuj txhua hnub, cov kav dej thiab khoom ua si.

Linear Low Density Polyethylene (LLDPE)
LLDPE muab cov kev hloov pauv ntawm LDPE thiab lub zog ntawm HDPE nrog kev ncab zoo thiab tsim kua muag. Nws feem ntau yog siv los ua cov yeeb yaj kiab nyuaj, xws li kev ua liaj ua teb thiab kev lag luam ntim cov yeeb yaj kiab.

Cov khoom ntawm PE yas
Kev nkag siab txog "Yuav ua li cas cov yas yog PE" yuav tsum tau saib tob dua ntawm nws cov khoom siv. Polyethylene muaj cov yam ntxwv sib txawv hauv qab no:
Zoo heev tshuaj stability
Polyethylene muaj kev tiv thaiv zoo rau feem ntau cov tshuaj xws li acids, alkalis thiab ntsev. Vim li no, cov ntaub ntawv PE feem ntau siv rau hauv cov ntim tshuaj thiab cov kav dej.

Kev tiv thaiv siab
Ob leeg high- thiab low-density polyethylene muaj kev cuam tshuam tsis zoo, uas ua rau lawv zoo heev rau kev ntim khoom thiab khaws cia.

Hluav taws xob rwb thaiv tsev
Polyethylene yog cov khoom siv hluav taws xob zoo heev thiab feem ntau siv rau sab nrauv ntawm cov xov hlau thiab cov cables kom ntseeg tau tias cov khoom siv hluav taws xob muaj kev nyab xeeb.

Kev siv cov PE yas
Qhov ntau ntawm cov ntawv thov rau polyethylene teb cov lus nug "PE yog dab tsi? Vim nws cov khoom sib txawv, PE cov ntaub ntawv tuav ib txoj haujlwm tseem ceeb hauv ntau qhov kev lag luam.
Ntim
Polyethylene ua lub luag haujlwm tseem ceeb hauv kev lag luam ntim khoom, tshwj xeeb tshaj yog nyob rau thaj tsam ntawm kev ntim khoom yooj yim, qhov twg PE hnab yas thiab cov yeeb yaj kiab yog cov kev siv ntau tshaj plaws ntawm PE hauv lub neej txhua hnub.

Kev Tsim Kho & Piping
High density polyethylene (HDPE) yog dav siv nyob rau hauv kev tsim kho kev lag luam rau piping, dej thiab roj kis tau tus mob kav vim nws corrosion thiab compression kuj zog.

Cov khoom siv thiab khoom siv hauv tsev
PE yas kuj tseem siv rau hauv cov khoom siv niaj hnub xws li cov khoom ua si, khoom siv hauv tsev thiab cov thawv ntim khoom. Cov khoom no tsis yog tsuas yog muaj kev nyab xeeb thiab tsis muaj tshuaj lom, tab sis kuj tuaj yeem siv rov ua dua los txo cov pa phem ib puag ncig.

Xaus
Yuav kom ua tiav, cov lus teb rau lo lus nug "PE yas yog dab tsi?" Cov lus teb rau lo lus nug no suav nrog ntau haiv neeg ntawm cov ntaub ntawv polyethylene thiab lawv cov kev siv ntau yam. Raws li cov khoom siv yas ruaj khov, tuaj yeem yooj yim thiab tus nqi qis, PE ua lub luag haujlwm tseem ceeb hauv txhua yam ntawm lub neej niaj hnub. Kev nkag siab txog nws hom thiab cov khoom sib txawv tuaj yeem pab peb ua qhov zoo tshaj plaws ntawm kev siv cov khoom siv no los txhawb kev lag luam thiab kev ua neej nyob.
