HCPE (Chlorinated roj hmab)
HCPE (Chlorinated roj hmab)
dawb lub teeb me me. Txij li cov qauv molecular tsis muaj ob daim ntawv cog lus thiab cov tshuaj chlorine atoms tau muab faib ua ntu zus, nws muaj huab cua tsis zoo, ozone tsis kam, kub laus tiv thaiv, nplaim hluav taws, tshuaj tiv thaiv thiab roj tsis kam. Siv los hloov chlorinated roj hmab hauv cov nplaum ntau lawm.
HCPE kuj tseem siv tau los ua cov nplaum, pleev xim, nplaim hluav taws kub, thiab cov qib siab tus cwj mem hloov pauv, uas tuaj yeem txhim kho adhesion, corrosion resistance, nplaim retardancy, thiab abrasion resistance. Siv cov khoom siv xim pleev xim, lub ntsiab tiv thaiv corrosion yog chloride ion, yog li thaum sib tsoo lub caij ntuj sov, thaum sib tsoo kub tshaj 60 ° C, nws yog ib qho tsim nyog yuav tau txiav txim siab txias los yog cais cov kev daws teeb meem ntxiv rau lub tank tiav, vim ntawm 56 ° C, chloride ion precipitates, Kev tiv thaiv corrosion ntawm cov xim yog txo, thiab hnyav los tiv thaiv corrosion xim yog siv.

Siv cov chlorinated roj hmab los ua cov nplaum. Nws kuj tseem tuaj yeem siv los ua kev hloov kho rau cov nplaum nplaum, qib siab inks thiab lwm yam khoom, uas tuaj yeem txhim kho adhesion, corrosion resistance, nplaim taws retardancy, thiab hnav-resistant qhov chaw. Khaws rau hauv qhov chaw txias, cua thiab qhuav warehouse, deb ntawm noo noo.
Vim cov qauv molecular tsis tu ncua, saturation, tsis tshua muaj polarity thiab zoo tshuaj stability ntawm chlorinated roj hmab, ntau yam anti-corrosion txheej npaj nrog nws muaj cov yam ntxwv ntawm ceev kom qhuav ntawm txheej zaj duab xis, zoo adhesion, tsis kam mus rau tshuaj lom neeg thiab zoo heev tiv taus rau ya raws. .
Highly chlorinated polyethylene HCPE muaj zoo heev atmospheric aging kuj thiab tshuaj nruab nrab tsis kam, yog yooj yim soluble nyob rau hauv aromatic hydrocarbons, esters, ketones thiab lwm yam organic solvents, thiab muaj zoo compatibility nrog feem ntau inorganic thiab organic pigments siv nyob rau hauv coatings. Feem ntau, nws yog tsim nyog rau dissolving rau hauv 40% cov ntsiab lus resin tov rau painting.
