Carboxymethylcellulose (CMC) hamwe na krahisi byombi ni polysaccharide, ariko bifite imiterere itandukanye, imitungo nibisabwa.
Ibigize molekulari:
1. Carboxymethylcellulose (CMC):
Carboxymethylcellulose ni inkomoko ya selile, polymer y'umurongo ugizwe na glucose ibice bihujwe na β-1,4-glycosidic. Guhindura selile bikubiyemo kwinjiza amatsinda ya carboxymethyl binyuze muri etherification, bikabyara carboxymethylcellulose. Itsinda rya carboxymethyl rituma CMC ibora amazi kandi igaha polymer ibintu byihariye.
2. Ibinyamisogwe:
Ibinyamisogwe ni karubone igizwe na glucose igizwe na α-1,4-glycosidic. Ni polymer karemano iboneka mubihingwa bikoreshwa mukubika ingufu. Molekile ya krahike igizwe nubwoko bubiri bwa glucose polymers: amylose (iminyururu igororotse) na amylopectine (imiterere yuruhererekane).
Imiterere yumubiri:
1. Carboxymethylcellulose (CMC):
Gukemura: CMC irashobora gukama amazi kubera ko hari amatsinda ya carboxymethyl.
Viscosity: Yerekana ububobere buke mu gisubizo, bigatuma igira agaciro mubikorwa bitandukanye nko gutunganya ibiryo na farumasi.
Gukorera mu mucyo: Ibisubizo bya CMC mubisanzwe biragaragara.
2. Ibinyamisogwe:
Gukemura: Ibinyamisogwe kavukire ntibishobora gushonga mumazi. Irasaba gelatinizasiyo (gushyushya mumazi) kugirango ishonga.
Viscosity: Paste paste ifite viscosity, ariko muri rusange iri munsi ya CMC.
Gukorera mu mucyo: Ibishishwa bya krahisi bikunda kuba bidasobanutse, kandi urwego rwubusa rushobora gutandukana bitewe nubwoko bwa krahisi.
isoko:
1. Carboxymethylcellulose (CMC):
Ubusanzwe CMC ikorwa muri selile ikomoka ku bimera nkibiti cyangwa ipamba.
2. Ibinyamisogwe:
Ibimera nk'ibigori, ingano, ibirayi n'umuceri bikungahaye kuri krahisi. Nibintu byingenzi mubiribwa byinshi byingenzi.
Uburyo bwo kubyaza umusaruro:
1. Carboxymethylcellulose (CMC):
Umusaruro wa CMC urimo etherification ya selile hamwe na aside ya chloroacetic muburyo bwa alkaline. Iyi reaction itera gusimbuza hydroxyl mumatsinda ya selile hamwe na carboxymethyl.
2. Ibinyamisogwe:
Gukuramo ibinyamisogwe bikubiyemo gusenya ingirabuzimafatizo no gutandukanya granules. Ibinyomoro byakuweho birashobora kunyura mubikorwa bitandukanye, harimo guhindura no gelatinizasi, kugirango ubone ibintu byifuzwa.
Intego no kuyishyira mu bikorwa:
1. Carboxymethylcellulose (CMC):
Inganda zibiribwa: CMC ikoreshwa nkibyimbye, stabilisateur na emulisiferi mubiribwa bitandukanye.
Imiti ya farumasi: Bitewe no guhuza no gusenya, isanga ikoreshwa muburyo bwa farumasi.
Gucukura amavuta: CMC ikoreshwa mumazi yo gucukura amavuta kugirango agenzure rheologiya.
2. Ibinyamisogwe:
Inganda zikora ibiribwa: Ibinyamisogwe nigice cyingenzi cyibiribwa byinshi kandi bikoreshwa nkibintu byongera umubyimba, gelling agent na stabilisateur.
Inganda zimyenda: Ibinyamisogwe bikoreshwa mubunini bwimyenda kugirango bitange gukomera kumyenda.
Inganda zimpapuro: Ibinyamisogwe bikoreshwa mugukora impapuro kugirango wongere imbaraga zimpapuro no kuzamura imiterere yubutaka.
Nubwo CMC hamwe na krahisi byombi ari polysaccharide, bifite itandukaniro mubice bya molekile, imiterere yumubiri, inkomoko, inzira yumusaruro hamwe nibisabwa. CMC irashobora gushonga amazi kandi igaragara cyane kandi ikundwa cyane mubisabwa bisaba iyi mitungo, mugihe ibinyamisogwe ari polysaccharide itandukanye ikoreshwa cyane mubiribwa, imyenda nimpapuro. Gusobanukirwa itandukaniro nibyingenzi guhitamo polymer ikwiye mubikorwa byinganda nubucuruzi.
