Ha o hlophisa sodium carboxymethyl cellulose (NaCMC) bakeng sa lits'ebetso tse fapaneng, lintlha tse 'maloa tsa bohlokoa li lokela ho nahanoa ho netefatsa ts'ebetso e nepahetseng le ho lumellana. Mona ke lintlha tse ka sehloohong tsa tlhokomelo:
Degree of Substitution (DS):
Tlhaloso: DS e bolela palo e tloaelehileng ea lihlopha tsa carboxymethyl ka unit ea anhydroglucose ka mokokotlong oa cellulose.
Bohlokoa: DS e ama ho solubility, viscosity, le ts'ebetso ea NaCMC. DS e phahameng hangata e eketsa ho solubility le viscosity.
Litlhoko tse khethehileng tsa kopo: Mohlala, lits'ebetsong tsa lijo, DS ea 0.65 ho isa ho 0.95 e tloaelehile, athe lits'ebetsong tsa indasteri, e ka fapana ho latela ts'ebeliso e itseng.
Viscosity:
Maemo a Tekanyo: Viscosity e lekanngoa tlas'a maemo a itseng (mohlala, mahloriso, mocheso, sekhahla sa ho kuta). Netefatsa maemo a ho lekanya a tsitsitseng bakeng sa ho ikatisa.
Khetho ea Kereiti: Khetha mofuta o nepahetseng oa viscosity bakeng sa kopo ea hau. Limaraka tse phahameng tsa viscosity li sebelisoa bakeng sa ho tenya le ho tsitsisa, ha limaraka tse tlase tsa viscosity li loketse lits'ebetso tse hlokang khanyetso e tlase ho phalla.
Bohloeki:
Litšila: Lekola litšila tse kang matsoai, selulose e sa sebetsanoang le lihlahisoa tse ling. NaCMC ea boleng bo holimo e bohlokoa bakeng sa ts'ebeliso ea meriana le lijo.
Tumellano: Netefatsa hore ho tsamaellana le litekanyetso tsa taolo tse amehang (mohlala, USP, EP, kapa litifikeiti tsa boemo ba lijo).
Boholo ba Karolo:
Sekhahla sa ho qhibiliha: Likaroloana tse nyenyane li qhibiliha ka potlako empa li ka baka mathata a ho sebetsana le mathata (mohlala, ho thehoa ha lerōle). Likaroloana tse mahoashe li qhibiliha butle empa ho bonolo ho li tšoara.
Ho Hlokahala Kopo: Bapisa boholo ba karoloana le litlhoko tsa kopo. Hangata li-powders tse ntle li ratoa lits'ebetsong tse hlokang ho qhibiliha kapele.
pH botsitso:
Buffer Capacity: NaCMC e ka thibela pH liphetoho, empa ts'ebetso ea eona e ka fapana ho ea ka pH. Ts'ebetso e nepahetseng hangata e mabapi le pH e sa nke lehlakore (6-8).
Compatibility: Etsa bonnete ba hore e tsamaellana le mofuta oa pH oa tikoloho ea tšebeliso ea pheletso. Lisebelisoa tse ling li ka hloka liphetoho tse khethehileng tsa pH bakeng sa ts'ebetso e nepahetseng.
Tšebelisano le lisebelisoa tse ling:
Liphello tsa Synergistic: NaCMC e ka sebelisana ka mokhoa o ts'oanang le li-hydrocolloids tse ling (mohlala, xanthan gum) ho fetola sebopeho le botsitso.
Ho se lumellane: Hlokomela ho se lumellane ho ka bang teng le metsoako e meng, haholo-holo ka metsoako e rarahaneng.
Solubility le Tokiso:
Mokhoa oa ho qhala: Latela mekhoa e khothaletsoang ea ho qhaqha NaCMC ho qoba ho putlama. Ka tloaelo, NaCMC e eketsoa butle-butle ho metsi a ferekaneng ka mocheso o haufi.
Nako ea Hydration: Lumella nako e lekaneng bakeng sa hydration e felletseng, kaha hydration e sa felletseng e ka ama ts'ebetso.
Thermal Stability:
Mamello ea Mocheso: NaCMC ka kakaretso e tsitsitse holim'a mefuta e mengata ea mocheso, empa ho pepesehela nako e telele mocheso o phahameng ho ka theola viscosity le ts'ebetso ea eona.
Maemo a Kopo: Nahana ka maemo a mocheso a kopo ea hau ho netefatsa botsitso le ts'ebetso.
Mehaho ea Taolo le Polokeho:
Tumellano: Netefatsa hore kereiti ea NaCMC e sebelisitsoeng e lumellana le litlhokahalo tse nepahetseng tsa taolo bakeng sa ts'ebeliso e reriloeng (mohlala, FDA, EFSA).
Safety Data Sheets (SDS): Hlahloba 'me u latele tataiso ea maqephe a tšireletso bakeng sa ho sebetsana le ho boloka.
Maemo a polokelo:
Lintlha tsa Tikoloho: Boloka sebakeng se phodileng, se omeletseng ho thibela ho monya le ho senyeha ha mongobo.
Sephutheloana: Sebelisa sephutheloana se nepahetseng ho itšireletsa khahlanong le tšoaetso le ho pepesehela tikoloho.
Ka ho nahanisisa ka lintlha tsena ka hloko, o ka ntlafatsa ts'ebetso le ho lekana ha sodium carboxymethyl cellulose bakeng sa ts'ebeliso ea hau e ikhethileng.
