HPMC E4M yog dab tsi?

HPMC E4M (Hydroxypropyl Methylcellulose E4M) yog ib hom cellulose ether uas yog siv rau ntau yam kev siv. Nws yog dej-soluble polymer muab tau los ntawm cellulose, uas yog ib tug natural polymer pom nyob rau hauv cov nroj tsuag. HPMC E4M yog cov hmoov dawb, tsis muaj ntxhiab tsw uas siv los ua tus neeg ua kom tuab, emulsifier, stabilizer, thiab tshem tawm tus neeg sawv cev hauv ntau yam kev lag luam.

HPMC E4M yog non-ionic, dej-soluble polymer uas yog siv rau ntau yam kev siv. Nws yog siv rau hauv kev lag luam tshuaj, zaub mov thiab dej haus, tshuaj pleev ib ce, thiab lwm yam lag luam. Hauv kev lag luam tshuaj, HPMC E4M yog siv los ua ib qho kev sib khi, disintegrant, thiab suspending agent. Hauv cov khoom noj thiab dej haus, nws yog siv los ua cov thickener, stabilizer, thiab emulsifier. Hauv cov tshuaj pleev ib ce, nws yog siv los ua cov thickener thiab stabilizer.

HPMC E4M yog ntau yam polymer uas tuaj yeem siv rau ntau yam kev siv. Nws yog siv los txhim kho kev ntxhib los mos thiab ruaj khov ntawm cov khoom. Nws kuj yog siv los ua kom cov viscosity ntawm cov kev daws teeb meem, txhim kho cov khoom ntws ntawm cov hmoov, thiab txo cov sedimentation ntawm cov khoom. HPMC E4M kuj tseem siv los ua tus neeg sawv cev ua yeeb yaj kiab, uas pab txhim kho lub txee lub neej ntawm cov khoom.

HPMC E4M yog cov khoom muaj kev nyab xeeb thiab muaj txiaj ntsig zoo uas siv rau ntau yam kev lag luam. Nws yog non-toxic thiab non-irritating, ua rau nws muaj kev nyab xeeb rau kev siv hauv cov khoom. Nws tseem yog non-allergenic thiab non-carcinogenic, ua rau nws muaj kev nyab xeeb rau kev siv hauv cov khoom noj thiab dej haus. HPMC E4M kuj yog biodegradable, ua rau nws xaiv ib puag ncig tus phooj ywg.

HPMC E4M yog cov khoom muaj ntau yam thiab muaj txiaj ntsig zoo uas siv rau ntau yam kev lag luam. Nws yog siv los txhim kho cov kev ntxhib los mos thiab ruaj khov ntawm cov khoom, ua kom cov viscosity ntawm cov kev daws teeb meem, txhim kho cov khoom ntws ntawm cov hmoov, txo cov sedimentation ntawm cov khoom, thiab ua raws li tus neeg sawv cev ua yeeb yaj kiab. Nws kuj tsis yog-tshuaj lom, tsis ua rau khaus, tsis yog-allergenic, thiab tsis-carcinogenic, ua rau nws muaj kev nyab xeeb thiab zoo rau kev siv hauv cov khoom. HPMC E4M kuj yog biodegradable, ua rau nws xaiv ib puag ncig tus phooj ywg.
