Ether cellulose miyuu milmi karaa?

Ether-ka Cellulose ayaa guud ahaan ku milma biyaha, taas oo ah mid ka mid ah sifooyinkooda muhiimka ah. milanka biyaha ee ethers cellulose waa natiijo ka timid wax ka beddelka kiimikaad ee lagu sameeyay polymer-ka cellulose ee dabiiciga ah. Ethers cellulose-ka caadiga ah, sida Methyl Cellulose (MC), Hydroxyethyl Cellulose (HEC), Hydroxypropyl Methyl Cellulose (HPMC), iyo Carboxymethyl Cellulose (CMC), waxay muujinayaan heerar kala duwan oo milmayn ah iyadoo ku xiran qaab-dhismeedkooda kiimikaad ee gaarka ah.

Halkan waxaa ah dulmar kooban oo ku saabsan milanka biyaha ee qaar ka mid ah ether-yada cellulose-ka caadiga ah:

  1. Methyl Cellulose (MC):
    • Methyl cellulose waxay ku milmaysaa biyo qabow, samaynta xal cad. Solubility waxaa saameyn ku leh heerka methylation, oo leh darajo sare oo beddelaad ah oo horseedaysa milanka hoose.
  2. Hydroxyethyl Cellulose (HEC):
    • Hydroxyethyl cellulose aad buu ugu milmay biyaha kulul iyo kuwa qabowba. Milkiyadeedu waa mid aan saameyn ku yeelan heerkulka.
  3. Hydroxypropyl Methyl Cellulose (HPMC):
    • HPMC waxay ku milmaysaa biyo qabow, oo milmayntoodu waxay kordhisaa heerkulka sare. Tani waxay u oggolaaneysaa muuqaal la xakameyn karo oo la beddeli karo.
  4. Carboxymethyl Cellulose (CMC):
    • Carboxymethyl cellulose waxay si diyaar ah ugu milmay biyo qabow. Waxay samaysaa xalal cad, oo muuqda oo leh xasilooni wanaagsan.

milanka biyaha ee ethers cellulose waa hanti muhiim ah oo gacan ka geysata isticmaalkooda baahsan ee codsiyada kala duwan ee warshadaha. Xalalka aqueous, polymers kuwanu waxay mari karaan hababka sida fuuq-baxa, bararka, iyo samaynta filimada, iyaga oo ka dhigaya kuwo qiimo leh qaababka sida xabagta, dahaarka, daawooyinka, iyo alaabta cuntada.

Waxaa muhiim ah in la ogaado in halka ether-ka cellulose ay guud ahaan ku milmi karaan biyaha, xaaladaha gaarka ah ee milanka (sida heerkulka iyo xoojinta) way kala duwanaan karaan iyadoo ku xiran nooca etherka cellulose iyo heerka beddelka. Soo-saareyaasha iyo soo-saareyaasha ayaa caadi ahaan tixgeliya arrimahan marka ay naqshadeynayaan badeecadaha iyo hab-samaynta.
