Yas Polyethylene (PE)

* PE yog yas polyethylene, uas tuaj yeem ua rau hauv zaj duab xis yas, hnab yas thiab ntau yam khoom. Yuav kom txo tau cov pa phem dawb, cov neeg sawv cev degradation tuaj yeem ntxiv rau cov yas kom ua tiav lub hom phiaj ntawm kev degradation sai, hom polyethylene no hu ua cov yas zoo rau ib puag ncig. Nws yog lub teeb yuag, ruaj khov, thiab yog ib qho ntawm cov yas feem ntau tsim tawm.

COV CIM HLUAV TAWS XOB ZOO TSHAJ PLAWS

Yas PE yog dab tsi?

Polyethylene hu ua PE, yog ib qho thermoplastic resin tsim los ntawm polymerization ntawm ethylene, yog cov qauv ntawm cov organic compounds polymer yooj yim tshaj plaws, lub ntiaj teb feem ntau siv PE polyethylene polymer cov ntaub ntawv, polymerization ntawm ethylene, raws li qhov sib txawv densities yog muab faib ua high-density polyethylene, medium-density polyethylene thiab low-density polyethylene.

Polyethylene tsis muaj ntxhiab, tsis muaj tshuaj lom, zoo li quav ciab, tiv taus kub tsawg heev (qhov kub siv qis tshaj plaws txog -100 ~ -70 ° C), ruaj khov tshuaj lom neeg zoo, tuaj yeem tiv taus feem ntau cov kua qaub thiab alkalis (tsis tiv taus cov khoom oxidizing ntawm cov kua qaub). Insoluble hauv cov kuab tshuaj dav dav ntawm chav tsev kub, nqus dej me me, rwb thaiv tsev zoo heev.

PE ua li cas?

Polyethylene yog ua los ntawm kev polymerization ntawm ethylene (lossis ethene) monomer. Cov saw hlau PE yog tsim los ntawm kev ntxiv lossis radical polymerization. Cov txheej txheem synthesis tau yog:

Ziegler-Natta Polymerization thiab

Kev ua tshuaj metallocene

Cov PE resins puas muaj tshuaj lom?

Hauv daim ntawv khov, Polyethylene suav hais tias muaj kev nyab xeeb thiab tsis muaj tshuaj lom. Lawv tuaj yeem lom yog tias nqus pa thiab / lossis nqus tau ua pa lossis kua (piv txwv li, thaum lub sijhawm tsim khoom).

Cov hom PE uas siv ntau yog dab tsi?

Nyob ntawm nws qhov ceev thiab kev sib ceg, cov qib PE sib txawv tuaj yeem muaj kev ua tau zoo sib txawv ntawm ib leeg.

Yog li ntawd, cov qib PE raug cais ua raws li hauv qab no.

Cov Qauv Uas Muaj Ceg

Cov polyethylene tsawg-density (LDPE)

Polyethylene uas tsis muaj zog ntau (LLDPE)

Cov Qauv Linear

Cov polyethylene ntom ntom (HDPE)

Polyethylene hnyav heev (UHMWPE)

Cov polyethylene txuas (PEX lossis XLPE)

Tsis tas li ntawd xwb, lwm hom PE kuj muaj xws li:

Polyethylene nruab nrab (MDPE)

Cov polyethylene uas tsis tshua muaj zog (ULDPE)

Polyethylene hnyav molecular siab (HMWPE)

Metallocene polyethylene (mPE)

Cov tshuaj chlorinated polyethylene (CPE)
