Kala firdhinta karboxymethyl cellulose waa in alaabtu ay ku milmi doonto biyaha, sidaas darteed kala-baxa alaabta ayaa sidoo kale noqotay hab lagu qiimeeyo waxqabadkeeda.Aan wax badan ka barano:
1) Qadar cayiman oo biyo ah ayaa lagu daraa nidaamka kala-firdhinta ee la helay, taas oo hagaajin karta kala firdhisanaanta qaybaha kolloid ee biyaha, waxaana lagama maarmaan ah in la hubiyo in cadadka biyaha lagu daray aysan milmin karin kolloidka.
2) Waxaa lagama maarmaan ah in lagu kala firdhiyo walxaha kolloidalka ah ee dhexdhexaadiyaha dareeraha ah ee biyaha ku jira, oo aan milmin biyaha-milmilaha ah ama aan biyo lahayn, laakiin waa in ay ka weyn tahay xajmiga kolloidal si ay si buuxda u kala firdhiso. .waa aalkolada monohydric ah sida methanol iyo ethanol, ethylene glycol, acetone, iwm.
3) Milix biyo-milmi leh waa in lagu daraa dareeraha qaada, laakiin milixdu kama falcelin karto kolloidka.Shaqadeeda ugu weyn waa inay ka hortagto jel-biyoodka-milmi kara inuu sameeyo koollo ama xinjirowga iyo roobka marka ay nasato.Inta badan loo isticmaalo waa chloride sodium iyo wixii la mid ah.
4) Waxaa lagama maarmaan ah in lagu daro wakiilka hakinta dareeraha qaadaha si looga hortago ifafaale roobaadka jel.Wakiilka ugu wayn ee hakinta wuxuu noqon karaa glycerin, hydroxypropyl methylcellulose, iwmCarboxymethyl cellulose, haddii glycerol loo isticmaalo wakiilka joojinta, qiyaasta caadiga ah waxay ku saabsan tahay 3% -10% dareeraha side.
5) Inta lagu jiro habka alkalization iyo etherification, cationic ama nonionic surfactants waa in lagu daraa, waana in lagu milmaa sidaha dareeraha ah si ay ugu habboonaato kolloidyada.Surfactants sida caadiga ah loo isticmaalo waa lauryl sulfate, glycerin Monoester, propylene glycol fatty acid ester, qiyaasteedu waxay ku saabsan tahay 0.05%-5% dareeraha side.
