Waa maxay HEMC?

Hydroxyethyl Methylcellulose (HEMC) waa derivative ether cellulose ah oo caadi ahaan loo isticmaalo sida wakiilka dhumuc, xasiliye, iyo wax lagu daro biyaha ee warshado kala duwan, gaar ahaan dhismaha, daawooyinka, iyo alaabta daryeelka shakhsi ahaaneed. Si la mid ah Hydroxypropyl Methylcellulose (HPMC), HEMC waxaa lagu farsameeyaa iyadoo lagu daweynayo cellulose leh ethylene oxide iyo methyl chloride, taasoo keentay xarun leh labada hydroxyethyl iyo methyl kooxaha ku xiran laf dhabarta cellulose.

HEMC waxay la wadaagtaa hanti badan HPMC, oo ay ku jiraan:

1. Haysashada Biyaha: HEMC waxay awood u leedahay inay nuugo oo hayso biyaha, taas oo ka dhigaysa mid waxtar u leh walxaha sibidhka sida maadada iyo xabagta dhoobada si looga hortago qalajinta degdega ah iyo hagaajinta shaqada.
2. Dhumucda: Waxay kordhin kartaa viscosity ee hababka dareeraha ah, taas oo faa'iido u leh codsiyada sida rinjiyada, dahaarka, iyo alaabta daryeelka shakhsi ahaaneed si loo gaaro joogtaynta la rabo.
3. Xasilinta: HEMC waxay caawisaa xasilinta emulsions iyo joojinta, ka hortagga kala-soocidda wejiga iyo ilaalinta isku-jirka alaabta.
4. Sameynta Filimada: Si la mid ah HPMC, HEMC waxay sameyn kartaa filim khafiif ah marka la marsado sagxadaha, taasoo bixisa ilaalin iyo kor u qaadida adhesion.
5. Guryaha socodka oo la hagaajiyay: Waxa ay wanaajin kartaa dabeecadaha socodka habaynta, fududaynta habaynta iyo codsiga.

HEMC waxaa badanaa laga doorbidaa HPMC codsiyada qaarkood sababtoo ah viscosity hoose iyo ku milmayn wanaagsan ee biyaha qabow. Si kastaba ha ahaatee, doorashada u dhaxaysa HEMC iyo HPMC waxay kuxirantahay shuruudaha qaabaynta iyo shuruudaha waxqabadka.

Marka la soo koobo, HEMC waa derivative cellulose ether oo kala duwan oo leh codsiyo kala duwan oo ka jira warshado kala duwan, halkaas oo sifooyinkeeda sida dhumuclaha, xasilinta, iyo wakiilka biyaha lagu hayo aad loo qiimeeyo.
