Habka kala dirida ee hydroxypropyl methylcellulose (HPMC)

Hydroxypropyl methylcellulose (HPMC) waxaa si weyn loogu isticmaalaa qalabka dhismaha, dahaarka, xabagta synthetic, ceramics, daawada, cuntada, dunta, beeraha, qurxinta, tubaakada iyo warshadaha kale. Hydroxypropyl methylcellulose (HPMC) waa eter cellulose aan-ionic ahayn oo laga sameeyay cellulose maadada polymer dabiiciga ah iyada oo loo marayo taxane kiimiko ah. Hydroxypropylmethylcellulose (HPMC) waa ur aan ur lahayn, dhadhamin, budo cad oo aan sun ahayn oo lagu milmi karo biyo qabow si loo sameeyo xal muuqda oo muuqda. Waxay leedahay sifooyin dhumuc, xidhidh, kala firdhiyo, emulsifying, filim samaynta, laalista, adsorbing, gelling, dusha firfircoon, ilaalinta qoyaan iyo ilaalinta kolloid.

Habka kala dirida ee hydroxypropyl methylcellulose (HPMC):

Alaabtani way barartaa oo ku firdhisaa biyaha kulul ee ka sarreeya 85°C, waxaana badanaa lagu milmaa hababka soo socda:

1. Qaado 1/3 qiyaasta biyaha kulul ee loo baahan yahay, walaaq si aad si buuxda u milmaan alaabta lagu daray, ka dibna ku dar inta kale ee biyaha kulul, kuwaas oo noqon kara biyo qabow, ama xataa biyo baraf ah, oo walaaq ilaa heerkulka ku habboon (20). °C), ka dibna si buuxda ayay u milmi doontaa. ah

2. Isku darka qallalan iyo isku darka:

Haddii ay dhacdo in lagu qaso budada kale, waa in si buuxda loogu qaso budada ka hor inta aan lagu darin biyaha, ka dibna si dhakhso ah ayaa loo milmi karaa iyada oo aan la kicin. ah

3. Habka qoynta dareeraha dabiiciga ah:

Marka hore ku kala dir badeecada dareere organic ah ama ku qoyso dareere organic ah, ka dibna ku dar biyo qabow si ay si fiican u milaan.
