Sodium carboxymethyl cellulose chimiro

Nhanganyaya

Carboxymethyl cellulose (CMC) imhando ye cellulose derivative inotorwa kubva ku cellulose ne carboxymethylation. Ihupfu huchena, husinganhuhwi, husina kunaka hunoshandiswa zvakanyanya mukudya, mishonga, zvizorwa, nemamwe maindasitiri. CMC ipolymer inonyungudika nemvura ine huwandu hwemashandisirwo nekuda kwehunhu hwayo hwakasiyana. Inoshandiswa seyakakora mumiriri, stabilizer, emulsifier, uye inomisa mumiriri. CMC inoshandiswawo sechidziviriro colloid mukugadzira mapepa nemachira.

Chimiro

Chimiro checarboxymethyl cellulose (CMC) inoumbwa nemutsara mutsara wemamorekuru eglucose anobatanidzwa pamwechete neglycosidic bond. Mamorekuru eglucose akabatana kune rimwe atomu reokisijeni, achigadzira mutsara weketani. Iyo mutsara cheni inobva yanzi carboxymethylated, zvinoreva kuti boka re carboxymethyl (CH2COOH) rakasungirirwa kuboka re hydroxyl (OH) yeglucose molecule. Iyi carboxymethylation process inoguma mune yakashata inochaja carboxymethyl cellulose molecule.

Chimiro checarboxymethyl cellulose chinogona kumiririrwa neinotevera fomula:

(C6H10O5)n-CH2COOH

uko n ndiyo dhigirii rekutsiva (DS) yeboka recarboxymethyl. Iyo dhigirii yekutsiva ndiyo nhamba yemapoka ecarboxymethyl paglucose molecule. Iyo yakakwirira iyo dhigirii yekutsiva, inokwira iyo viscosity yeCMC mhinduro.

Properties Carboxymethyl cellulose ine akati wandei akasiyana zvivakwa zvinoita kuti ive yakakosha mumhando dzakasiyana dzekushandisa. Iyo i polymer inonyungudika nemvura iyo yakagadzikana zvakanyanya mumhinduro dzine aqueous. Izvo zvakare isiri-chepfu, isingatsamwise, uye isiri-allergenic. CMC zvakare inoshingirira kusvibiswa kwehutachiona uye haina kukanganiswa nepH kana tembiricha. CMC chinhu chakasimba chekukora uye chinogona kushandiswa kukobvuta zvinwiwa zvakasiyana siyana, zvinosanganisira chikafu, mishonga yemishonga, uye zvekuzora. Inoshandiswawo se emulsifier, stabilizer, uye kumisa mumiririri. CMC inoshandiswawo sechidziviriro colloid mukugadzira mapepa nemachira. Mhe. Ihupfu huchena, husinganhuhwi, husina kunaka hunoshandiswa zvakanyanya mukudya, mishonga, zvizoro, nemamwe maindasitiri. CMC inoumbwa nemutsara cheni yemamorekuru eglucose ayo akabatanidzwa pamwechete neglycosidic bond uye carboxymethylated. Iine huwandu hwezvinhu zvakasiyana-siyana zvinoita kuti zvive zvakakosha mune zvakasiyana-siyana zvekushandisa. CMC isimbi yakasimba yekukora uye inogona kushandiswa se emulsifier, stabilizer, uye kumisa mumiriri. Inoshandiswawo sechidziviriro colloid mukugadzira mapepa uye machira.
