Sodium carboxymethyl cellulose e sebelisoa haholo ka peterole, lijo, meriana, masela, ho etsa pampiri le liindasteri tse ling, kahoo ke habohlokoa haholo ho ahlola ka nepo bohloeki ba eona, hape ke tekanyo ea ho etsa bonnete ba hore tšebeliso ea eona e na le phello, joale, Re ka bona joang? ho fofonela, ho ama, le ho nyeka ho ahlola bohloeki ba eona?
1. Sodium carboxymethyl cellulose e nang le bohloeki bo phahameng e na le ho boloka metsi ho feteletseng, ho fetisa khanya e ntle, 'me sekhahla sa eona sa ho boloka metsi se ka holimo ho 97%.
2. Lihlahisoa tse nang le bohloeki bo phahameng li ke ke tsa fofonela monko oa ammonia, starch le joala, empa haeba li na le bohloeki bo tlaase, li ka fofonela mefuta e sa tšoaneng ea tatso.
3. Selulose se hloekileng sa sodium carboxymethyl se na le ponahalo ea fluffy, 'me bongata bo bongata bo nyane, mefuta e mengata ke: 0.3-0.4 / ml;mokelikeli oa bohlola o molemo, letsoho le ikutloa le le boima, 'me ho na le phapang e khōlō ka ponahalo ea pele.
4. Kakaretso ea chloride ea CMC e baloa ho CL, ka mor'a hore CL e lekantsoe, litaba tsa NaCl li ka fetoloa CL%*1.65
Ho na le kamano e itseng lipakeng tsa litaba tsa CMC le chloride, empa eseng kaofela, ho na le litšila tse kang sodium glycolate.Ka mor'a ho tseba bohloeki, litaba tsa NaCl li ka baloa NaCl%=(100-purity)/1.5

Ka hona, sehlahisoa sa ho nyeka leleme se na le tatso e matla ea letsoai, e bontšang hore bohloeki ha bo phahame.
Ka nako e ts'oanang, sodium carboxymethyl cellulose e hloekileng haholo ke boemo bo tloaelehileng ba fiber, ha lihlahisoa tse tlaase li le granular.Ha u reka sehlahisoa, u tlameha ho ithuta mekhoa e 'maloa e bonolo ea ho tsebahatsa.Ho phaella moo, o tlameha ho khetha moetsi ea nang le botumo bo botle, e le hore boleng ba sehlahisoa bo tiisetsoe haholoanyane.
