HDPE cov khoom siv yog dab tsi? Cov yam ntxwv tsom xam ntawm cov yam ntxwv thiab kev siv ntawm cov qib siab polyethylene
Hauv kev lag luam tshuaj, HDPE yog cov khoom tseem ceeb heev, nws lub npe tag nrho yog cov qib siab polyethylene (high-ntom polyethylene) .What kiag yog HDPE? Kab lus no yuav muab koj cov lus teb koj cov ncauj lus kom ntxaws thiab kev ntsuas ntawm cov yam ntxwv ntawm HDPE, nws cov txheej txheem ntau lawm thiab nws cov kev siv ntau lawm.
Cov ntsiab lus yooj yim thiab cov qauv tshuaj ntawm HDPE
HDPE yog dab tsi? Los ntawm cov tshuaj ntsuam pom, HDPE yog ib thermoplicity polymer tsim los ntawm qhov sib ntxiv polymerisation ntawm ethylene monomers. Nws cov qauv molecular yog cov cim los ntawm cov saw ntev polyethylene nrog cov siab txheeb ze cov roj av thiab tsawg dua cov nplais sib txuas ntawm lawv, ua rau muaj kev sib zog sib xyaw. Qhov no nthuav dav molecular kev npaj muab HDPE lub siab nyob hauv tsev neeg Polyethylene, feem ntau ntawm 0.940 g / cms0 g / cm³.
Zoo tshaj cov khoom ntiag tug ntawm HDPE
HDPE cov khoom pov thawj khoom siv ntau yam khoom siv lub cev zoo vim nws cov qauv molecular. Nws muaj lub zog siab thiab tuaj yeem tiv taus cov tshuaj lom neeg zoo, uas ua rau nws zoo heev hauv cov tshuaj zoo, uas ua rau nws muaj txiaj ntsig zoo rau kev khaws cov tshuaj.
HDPE kuj muaj qhov qis qis qis-kub tsis kam, muaj peev xwm tswj nws txoj kev nruj me ntsis nyob rau ib puag ncig kom tsawg li -40 ° C tsis muaj nkig. Nws tseem muaj hluav taws xob hluav taws xob cov khoom siv hluav taws xob, uas tau ua rau nws siv nyob rau hauv cov xov hlau thiab cable.
HDPE Cov Txheej Txheem Ntau Lawm thiab Kev Ua Qauv
Tom qab to taub dab tsi ntawm cov khoom HDPE yog, cia saib nws cov txheej txheem ntau lawm, piv txwv li cov khoom siv zoo heev lossis slurry polymerisation txoj kev. Cov txheej txheem no tshwm sim hauv HDPE nrog qis crystallinity thiab siab crystallisation tus nqi, ua rau muaj kev kub siab cov khoom siv polyethylene.
HDPE cov ntaub ntawv muaj cov txheej txheem zoo thiab tuaj yeem siv tau los ntawm ntau txoj kev ua tiav, xws li txhaj tshuaj molding, tshuab moulding thiab extrusion molding. Raws li qhov tshwm sim, HDPE tuaj yeem ua ntau hom khoom xws li cov kav dej, cov yeeb yaj kiab, hwj thiab cov ntim yas.
Ntau yam ntawm daim ntawv thov cov chaw rau HDPE
Vim yog cov khoom muaj ntau yam zoo ntawm cov khoom siv HDPE, nws yog dav siv hauv kev lag luam ntau yam. Hauv kev lag luam ntim khoom, HDPE feem ntau siv nyob rau hauv kev tsim ntawm ntau hom hluav taws xob, cov raj mis ntim khoom, cov khoom noj kom zoo kom ua rau lub ntim khoom ntev. Hauv kev tsim kho kev tsim kho, HDPE yog siv los ua cov dej mov thiab cov kav dej paug thiab cov kev tsis kam ua rau nws muaj kev cuam tshuam rau qhov chaw hnyav.
Hauv kev ua liaj ua teb kev ua liaj ua teb, HDPE yog siv los ua cov yeeb yaj kiab ua liaj ua teb, qhov chaw UPTANTE Ua kom tau siv cov qoob loo ntawm cov xov hlau thiab cov xaim hluav taws xob, nrog rau hauv Ntau yam tshuaj rau ntau yam tshuaj lom neeg hlau thiab ntim.
Tag
HDPE yog cov khoom siv thermoplastrastic polymer nrog cov khoom zoo xws li muaj zog, tshuaj lom neeg tsis kam thiab ua tau yooj yim. Nws muaj ntau cov ntawv thov hauv tshuaj, kev tsim kho, kev ua liaj ua teb thiab lwm thaj teb. Yog tias koj tseem xav "dab tsi yog cov ntawv HDPE", cia siab rau ntawm cov yam ntxwv HDPE, HDPE yeej tsis ntseeg ib qho ntawm cov khoom siv tsis tseem ceeb hauv kev lag luam niaj hnub.
