Kushandiswa kwe sodium carboxymethyl cellulose uye hydroxyethyl cellulose mune zvemazuva ese makemikari zvigadzirwa

Carboxymethylcellulose sodium (CMC-Na) chinhu cheorganic, chinotorwa necarboxymethylated kubva kune cellulose, uye inonyanya kukosha ionic cellulose chingamu. Sodium carboxymethyl cellulose inowanzoita anionic polymer compound yakagadzirwa nekuita selulosi yechisikigo ine caustic alkali uye monochloroacetic acid, ine huremu hwemamorekuru kubva kuzviuru zvakati kusvika kumamiriyoni. CMC-Na ichena fibrous kana granular poda, isinganhuhwi, isinganakidze, hygroscopic, iri nyore kupararira mumvura kuita inoonekera colloidal mhinduro.

Kana kusarerekera kana alkaline, mhinduro ndeye yakakwirira-viscosity mvura. Yakagadzikana kumishonga, chiedza uye kupisa. Zvisinei, kupisa kunogumira ku80°C, uye kana inopisa kwenguva yakareba kupfuura 80°C, iyo viscosity ichadzikira uye haizonyungudika mumvura.

Sodium carboxymethyl cellulose zvakare imhando yekukora. Nekuda kwemaitiro ayo akanaka ekushanda, yakashandiswa zvakanyanya muindasitiri yezvekudya, uye yakasimudzira kukurumidza uye kune hutano kusimudzira kweindasitiri yezvekudya kusvika pamwero wakati. Semuenzaniso, nekuda kwekumwe kukora uye emulsifying mhedzisiro, inogona kushandiswa kudzikamisa yogurt zvinwiwa uye kuwedzera viscosity yeyoghurt system; nekuda kwehumwe hydrophilicity uye rehydration zvivakwa, inogona kushandiswa kuvandudza manwiro epasta senge chingwa nechingwa chakabikwa. mhando, wedzera hupenyu hwesherufu yezvigadzirwa zvepasta uye kuwedzera kuravira.

Nemhaka yokuti ine imwe gel effect, inobatsira kune chikafu kuti iite gel zviri nani, saka inogona kushandiswa kugadzira jelly uye jam; inogona zvakare kushandiswa sechinhu chinodyika chekuputira, chakasanganiswa nemamwe makobvu, uye kupararira Pane dzimwe nzvimbo dzechikafu, inogona kuchengetedza chikafu chiri chitsva kusvika pamwero mukuru, uye nekuti chiri chinhu chinodyiwa, hachizokonzere mhedzisiro pamunhu. utano. Naizvozvo, chikafu-giredhi CMC-Na, seyakanaka chekuwedzera chikafu, chinoshandiswa zvakanyanya mukugadzira chikafu muindasitiri yechikafu.

Hydroxyethylcellulose (HEC), kemikari formula (C2H6O2) n, ichena kana kujeka yero, isinganhuhwi, isina-chepfu fibrous kana upfu hwakasimba, inoumbwa nealkaline cellulose uye ethylene oxide (kana chlorohydrin) Yakagadzirirwa ne etherification reaction, ndeye isiri- Ionic soluble cellulose ethers. Nekuti HEC ine zvinhu zvakanaka zvekukora, kumisa, kuparadzira, emulsifying, kusunga, kugadzira firimu, kuchengetedza unyoro uye kupa inodzivirira colloid.

Zviri nyore soluble mumvura pa20°C. Isinganyunguriki mune zvakajairika organic zvinonyungudutsa. Iine mabasa ekukora, kumisa, kusunga, emulsifying, kuparadzira, uye kuchengetedza mwando. Mhinduro mumhando dzakasiyana dze viscosity dzinogona kugadzirirwa. Iine yakasarudzika yakanaka munyu solubility kune electrolytes.

Iyo viscosity inoshanduka zvishoma muhuwandu hwePH kukosha 2-12, asi viscosity inoderera kupfuura iyi chiyero. Iine maitiro ekukora, kumisa, kusunga, emulsifying, kuparadzira, kuchengetedza unyoro uye kudzivirira colloid. Mhinduro mumhando dzakasiyana dze viscosity dzinogona kugadzirirwa.
