Sida surfactant aan-ionic ahayn,hydroxyethyl cellulose(HEC) waxay leedahay sifooyinka soo socda marka lagu daro dhumuc, laalitaan, xidhidh, sabbeyn, filim samayn, kala firdhinta, haysashada biyaha iyo bixinta kolloidyada ilaalinta:
1. HEC waxay ku milmi kartaa biyo kulul ama qabow, oo kuma soo daadin heerkulka sare ama karkarinta, sidaas darteed waxay leedahay noocyo kala duwan oo milmayn iyo sifooyin viscosity, iyo gelation non-thermal;
2. Ionic aan ahayn lafteedu waxay la noolaan kartaa polymers kale oo biyo-milmi leh, surfactants iyo milix oo kala duwan, waana dhumuc weyn oo kolloid ah oo ka kooban xalal koronto leh oo sarreeya;
3. Awoodda haynta biyuhu waxay laban laab ka badan tahay tan methyl cellulose, waxayna leedahay nidaaminta qulqulka wanaagsan.
4. Marka la barbar dhigo methyl cellulose ee la aqoonsan yahay iyo hydroxypropyl methyl cellulose, awoodda kala firdhisan ee HEC waa tan ugu xun, laakiin awoodda kolloid ilaalinta ayaa ah kan ugu xooggan.
Sida loo isticmaalo hydroxyethyl cellulose?
1. Si toos ah ugu biir wax soo saarka
1. Ku dar biyo nadiif ah baaldi weyn oo ay ku rakiban yihiin blender dhogorta sare leh.
2. Bilow inaad si joogto ah u walaaqdo xawaare hooseeya oo si tartiib ah u kala miir hydroxyethyl cellulose si siman xalka.
3. Sii wad walaaq ilaa dhammaan qaybaha la qooyay.
4. Ka dibna ku dar wakiilka ilaalinta hillaaca, waxyaabaha alkaline-ka lagu daro sida midabada, qalabka kala firdhiya, biyaha ammonia.
5. Walaaq ilaa dhammaan cellulose hydroxyethyl ay si buuxda u milmaan (viskosity ee xalku si weyn ayuu u kordhay) ka hor intaadan ku darin qaybaha kale ee caanaha, oo shiid ilaa ay noqoto
