Waa maxay MHEC?

Methyl Hydroxyethyl Cellulose (MHEC) waa derivative eter cellulose si weyn loogu isticmaalo warshadaha sida dhismaha, daawooyinka, iyo alaabta daryeelka shakhsi ahaaneed. Waxaa lagu farsameeyaa iyada oo ka falcelinaysa cellulose leh ethylene oxide iyo methyl chloride, taas oo keentay xarun leh labadaba hydroxyethyl iyo methyl kooxaha ku xiran laf-dhabarka cellulose.

MHEC waxay hanti badan la wadaagtaa ether-ka cellulose-ka sida Hydroxypropyl Methylcellulose (HPMC) iyo Hydroxyethyl Methylcellulose (HEMC), oo ay ku jiraan:

1. Haysashada Biyaha: MHEC waxa ay awood u leedahay in ay nuugo oo ay hayso biyaha, taas oo ka dhigaysa mid faa'iido u leh qalabka dhismaha sida hoobiye, grouts, iyo xabagta dhoobada si looga hortago qallayl degdeg ah oo loo hagaajiyo 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: MHEC waxay gacan ka geysataa xasilinta emulsions iyo ganaaxyada, ka hortagga kala-soocidda wejiga iyo ilaalinta isku-jirka alaabta.
4. Sameynta Filimada: Si la mid ah ether-ka cellulose-ka kale, MHEC waxay sameyn kartaa filim khafiif ah marka la marsado sagxadaha, taasoo bixisa ilaalin iyo xoojinta adhesion.
5. Guryaha socodka oo la hagaajiyay: Waxa ay wanaajin kartaa dabeecadaha socodka habaynta, fududaynta habaynta iyo codsiga.

MHEC waxaa badanaa lagu doortaa isku-dhafka gaarka ah ee guryaha, sida awoodda ay u leedahay inay bixiso biyo-hayn wanaagsan iyada oo la ilaalinayo viscosity hoose marka la barbar dhigo eter-yada kale ee cellulose. Tani waxay si gaar ah ugu habboon tahay codsiyada halka loo baahan yahay haynta biyaha sare iyada oo aan si xad dhaaf ah loo kordhinayn viscosity ee qaabaynta.

Methyl Hydroxyethyl Cellulose (MHEC) waa derivative cellulose ether badan oo kala duwan oo codsiyo, halkaas oo ay sifooyin sida dhumuc weyn, xasiliye, wakiilka biyaha-hayn, iyo filim hore ayaa aad loo qiimeeyo.
