I-Carboxymethylcelcelcellellose (CMC) ne-methylcellulose (MC) zombili ezivela kumaselula, i-polymer yemvelo etholakala ezindongeni zeseli zezitshalo. Lezi zindlela zokutholwa zithola ukusetshenziswa okubanzi kwizimboni ezahlukahlukene ngenxa yezakhiwo zazo ezihlukile. Ngaphandle kokuhlukahluka, i-CMC ne-MC banomehluko ohlukile ezinhlakeni zabo zamakhemikhali, izakhiwo, ukusetshenziswa, kanye nokusetshenziswa kwezimboni.
Isakhiwo se-1.Chical:
I-Carboxymethylcelcellellulose (CMC):
I-CMC ihlelwe ngokuthethelwa kwe-cellulose nge-chlorosetic acid, okuholela ekufakweni kwamaqembu we-hydroxyl (-OH) kwi-cellulose backbone ngamaqembu e-carboxymethyl (-CH2OOH).
Izinga lokufakwa esikhundleni (DS) ku-CMC libhekisela kwinani eliphakathi lamaqembu e-carboxymethyl. Le pharamitha inquma izakhiwo ze-CMC, kufaka phakathi i-solubity, ukuhlakanipha kanye nokuziphatha kwe-bhe ngokomzimba.
Methylcellulose (MC):
I-MC ikhiqizwa ngokufakwa esikhundleni samaqembu e-hydroxyl eCellulose enamaqembu we-methyl (-CH3) ngokuthezeka.
Ifana ne-CMC, izakhiwo ze-MC zithonywa ngezinga lokufakwa esikhundleni, elinquma ubukhulu be-methylation eceleni kwe-cellulose chain.
2.Solility:
I-Carboxymethylcelcellellulose (CMC):
I-CMC incane emanzini futhi yakha okusobala, izixazululo ze-viscous.
I-solubility yayo incike e-PH-inceku, nge-solubility ephakeme ezimeni ze-alkaline.
Methylcellulose (MC):
I-MC nayo incibilika emanzini, kepha i-solubility yayo incike kulimo.
Lapho ichithwa emanzini abandayo, i-MC yakha ijeli, elihlabelela ngokufudumeza. Le mpahla yenza ukuthi ilungele izinhlelo zokusebenza ezidinga ukulawulwa okulawulwayo.
Uku- (Viviscute:
CMC:
Ibonisa ukubonakala okuphezulu ezixazululweni zamanzi, kufaka isandla kwizakhiwo zayo zokuqina.
I-viscosity yayo ingashintshwa ngokulungiswa kwezinto ezifana nokuhlushwa, isilinganiso sokufaka esikhundleni, kanye no-pH.
MC:
Ibonisa isimilo se-Viscosity esifana ne-CMC kepha ngokuvamile i-viscous kancane.
I-viscosity ye-MC Solutions nayo ingalawulwa ngokuguqula amapharamitha afana nokushisa kanye nokuhlushwa.
Ukusungulwa kwe-4.Film:
CMC:
Amafilimu acacile, avumelana nezimo lapho aphonswa ezixazululweni zawo ezinamanzi.
Lawa mafilimu athola izinhlelo zokusebenza ezimbonini ezinjengokupakishwa kokudla kanye nemithi yezemithi.
MC:
Okunye futhi okwazi ukwakha amafilimu kepha kuvame ukuba brittle ngokwengeziwe uma kuqhathaniswa namafilimu e-CMC.
Imboni ye-5.Food:
CMC:
Kusetshenziswe kabanzi njenge-stabilizer, umkhulu, kanye ne-emulsifier emikhiqizweni yokudla efana ne-ayisikhilimu, amasoso kanye nokugqoka.
Amandla awo okuguqula ukuthungwa kanye nomlomo wezinto zokudla kwenza kube yigugu ekwakhiweni kokudla.
MC:
Isetshenziselwa izinhloso ezifanayo njenge-CMC emikhiqizweni yokudla, ikakhulukazi kwizicelo ezidinga ukwakheka kwe-gel kanye nokuzinza.
Ama-6.Huraceuticals:
CMC:
Kusetshenziswe ekwakhiweni kwemithi njenge-binder, ukuqhelelana, kanye ne-viscosity modifier ekukhiqizeni ithebhulethi.
Futhi oqashwe ekwakhiweni okuphezulu okufana nokhilimu nama-gels ngenxa yezakhiwo zayo ze-rhelogical.
MC:
Isetshenziswa kakhulu njenge-ejenti enkulu kanye ne-gelling e-ejenti emikhakheni, ikakhulukazi emithini ye-Oral Liquid nasezixazulukweni ze-Ophthalmic.
7.Pesonal Care Products:
CMC:
Kutholakala ezintweni ezihlukene zokunakekelwa komuntu siqu njengezinyo lamazinyo, i-shampoo, kanye ne-lotions njenge-stabilizer kanye ne-ejenti yokuqina.
MC:
Isetshenziswe kuzinhlelo zokusebenza ezifanayo ne-CMC, ifaka isandla ekuthumelweni nasekuqineni kokwenziwa komuntu siqu.
8.Izicelo zezimboni:
CMC:
Iqashwe ezimbonini ezinjengezimboni ezinjengezindwangu, iphepha, nama-ceramics amandla ayo okwenza njenge-binder, i-rheology modifier, ne-ejenti yokugcinwa kwamanzi.
MC:
Ithola ukusetshenziswa kwezinto zokwakha, upende, kanye nezinamathela ngenxa yezakhiwo zayo ezihlanganayo nezibophayo.
Ngenkathi i-carboxymethylcelcellellose (CMC) ne-methylcellulose (MC) zombili izinto ze-mellulose zitholakala ngezicelo ezahlukahlukene zezimboni, zibonisa umehluko ezinhlanganweni zazo zamakhemikhali, ukuziphatha kwe-solubity, amaphrofayli e-viscosity, kanye nezicelo. Ukuqonda lokhu umehluko kubalulekile ekukhetheni okususelwa ekusetshenzisweni okuqondile kokusetshenziswa okukhethekile ezimbonini ezahlukahlukene, kusukela ekudleni nasemikhakheni emikhakheni kuya ekunakekelweni komuntu siqu kanye nezicelo zezimboni. Noma ngabe yisidingo esikhulu se-PH-Sweener njenge-CMC emikhiqizweni yokudla noma i-ejenti yokuphendula ama-gelling enesilinganiso se-MC ekwakhiweni kwemithi, okususelwa ngakunye kunikeza izinzuzo ezihlukile ezenzelwe imikhakha ehlukene.
