HCPE (Chlorinated roj hmab)
HCPE (Chlorinated roj hmab)
cov khoom me me dawb. Vim tias cov qauv molecular tsis muaj ob daim ntawv cog lus thiab cov chlorine atoms raug faib ua ntau yam, nws muaj kev tiv taus huab cua zoo, tiv taus ozone, tiv taus kub laus, tiv taus hluav taws, tiv taus tshuaj lom neeg thiab tiv taus roj. Siv los hloov cov roj hmab chlorinated hauv kev tsim cov nplaum.
HCPE kuj tseem siv tau ua cov nplaum, xim, cov tshuaj tiv thaiv hluav taws, thiab cov kua mem zoo, uas tuaj yeem txhim kho kev nplaum, kev tiv thaiv corrosion, hluav taws retardancy, thiab kev tiv thaiv abrasion. Siv ua cov khoom siv xim, cov nyhuv tiv thaiv corrosion tseem ceeb yog chloride ion, yog li thaum sib tsoo thaum lub caij ntuj sov, thaum qhov kub sib tsoo tshaj 60 ° C, nws yog qhov tsim nyog los xav txog kev txias lossis sib cais teeb tsa cov tshuaj ntxiv rau hauv lub tank tiav, vim tias ntawm 56 ° C, chloride ion precipitates, Kev ua haujlwm tiv thaiv corrosion ntawm cov xim raug txo qis, thiab cov xim tiv thaiv corrosion hnyav raug siv.

Siv hloov cov roj hmab chlorine los ua cov nplaum. Nws kuj tseem siv tau ua cov khoom hloov kho rau cov nplaum, cov kua mem zoo thiab lwm yam khoom, uas tuaj yeem txhim kho kev nplaum, kev tiv thaiv xeb, kev tiv thaiv hluav taws, thiab cov khoom uas tiv taus kev hnav. Khaws cia rau hauv qhov chaw txias, cua nkag thiab qhuav, deb ntawm cov dej noo.
Vim yog cov qauv molecular tsis tu ncua, saturation, qis polarity thiab zoo tshuaj stability ntawm chlorinated roj hmab, ntau yam tshuaj tiv thaiv corrosion npaj nrog nws muaj cov yam ntxwv ntawm kev qhuav sai ntawm cov txheej zaj duab xis, zoo adhesion, tsis kam rau cov tshuaj lom neeg thiab zoo heev tsis kam rau dej nkag.
Polyethylene HCPE uas muaj chlorine ntau heev muaj kev tiv taus huab cua zoo heev thiab tiv taus cov tshuaj lom neeg nruab nrab, yooj yim yaj hauv cov hydrocarbons uas muaj ntxhiab tsw qab, esters, ketones thiab lwm yam organic solvents, thiab muaj kev sib raug zoo nrog feem ntau cov inorganic thiab organic pigments siv hauv cov txheej txheem. Feem ntau, nws tsim nyog rau kev yaj rau hauv 40% cov khoom khov kho cov tshuaj resin rau kev pleev xim.
