Polyethylene CAS 9002-88-4
Polyethylene yog ib hom roj hydrocarbon uas muaj cov qauv zoo ib yam li paraffin, uas yog cov khoom siv hluavtaws hnyav molecular siab uas ua los ntawm kev polymerizing ethylene. Cov molecule Polyethylene tsis muaj polarity genes, nqus dej tsawg, thiab ruaj khov zoo. Insoluble hauv cov kuab tshuaj ib txwm muaj ntawm chav tsev kub, ruaj khov rau cawv, ethers, ketones, esters, cov kua qaub tsis muaj zog, thiab cov hauv paus tsis muaj zog. Tab sis nws tuaj yeem o hauv cov roj hydrocarbons, aromatic hydrocarbons, thiab halogenated hydrocarbons, raug corroded los ntawm cov kua qaub muaj zog oxygen, thiab dhau los ua oxidation thaum cua sov lossis ci hauv huab cua.

1. Polyethylene tuaj yeem ua tiav rau hauv cov yeeb yaj kiab, cov hlau thiab cov hlua khi, cov kav dej, ntau yam khoom hollow, cov khoom txhaj tshuaj molded, fibers, thiab lwm yam. Nws yog dav siv hauv kev lag luam xws li kev ua liaj ua teb, ntim khoom, thiab tsheb.
2. PE siv tau los tsim cov yas profiles thiab cov roj hmab additives,
3. Nws siv tau ua cov khoom ntim rau cov khoom lag luam thiab cov khoom ua liaj ua teb, khoom noj, zaj duab xis npog cov noob qoob loo, zaj duab xis channel thiab reservoir anti-seepage, thiab lwm yam.
4. Siv rau hauv kev lag luam khoom noj ua khoom noj khoom haus.
5. Siv ua ib qho kev hloov rau hlau, nws kuj tseem siv tau ua cov yeeb yaj kiab tshwj xeeb, cov thawv loj, cov kav dej loj, cov phaj, thiab cov ntaub ntawv sintered. Daim ntawv thov
Feem ntau ntim rau hauv 25kg / nruas, thiab kuj tuaj yeem ua pob khoom raws li koj xav tau.
