Hydrocolloid: cellulose pos hniav

Hydrocolloids yog chav kawm ntawm cov tebchaw uas muaj lub peev xwm los ua cov tshuaj pleev lossis cov kev daws teeb meem thaum tawg hauv dej. Cellulose cov hniav cov hniav, tseem hu ua carboxymethyl cellulose (cmc) lossis cellulose cellboxymethil ete, yog ib txwm siv hydrodoid ete, yog cov duab ntshiab ntawm cellulose, lub ntuj polymer pom hauv tsob ntoo cell phab ntsa. Ntawm no yog yam koj yuav tsum paub txog cov pos hniav cellulose ua ib qho hydrocolloid:

Cov yam ntxwv ntawm cellulose cov pos hniav:

1. Dej so: Cellulose cov hniav yog soluble hauv dej, ua cov kev daws teeb meem meej thiab cov txiv neej nyob ntawm cov kev xav thiab cov xwm txheej. Cov cuab yeej no ua rau nws yooj yim rau kev sib xyaw ua ke rau aqueous formulations thiab kho viscosity.
2. Thickening: cellulose cov pos hniav yog ib qho zoo ua kom tuab, muaj peev xwm nce lub viscosity ntawm cov kev daws teeb meem aqueous thiab ncua kev ncua. Nws imparts pseudoplastic los yog shear-thinning tus cwj pwm, lub ntsiab lus nws viscosity txo qis nyob rau hauv shear kev ntxhov siab thiab rov qab thaum cov kev ntxhov siab raug tshem tawm.
3. Stabilization: Cellulose cov pos hniav ua raws li lub stabilizer thiab emulsifier hauv cov zaub mov thiab dej haus, tiv thaiv theem sib cais, kev ua yeeb yam, lossis crystallization, lossis crystallization, lossis crystallization. Nws pab txhim kho lub neej txee, kev ntxhib los mos, thiab qhov ncauj ntawm cov khoom xws li cov kua ntses, hnav khaub ncaws, thiab khoom qab zib.
4. Zaj duab xis-tsim: Cellulose cov pos hniav tuaj yeem sau cov yeeb yaj kiab thiab pleev xim rau thaum qhuav, ua yeeb yaj kiab, thiab muaj cas. Cov yeeb yaj kiab ua yeeb yam ntawm cov pos hniav cellulose ua rau txhim kho cov khoom muaj teeb meem, noo noo khaws cia, thiab kev tiv thaiv nto.
5. Kev ncua: Cellulose ntawm cov pos hniav muaj peev xwm txiav tsis muaj cov khoom xyaw ua kua lossis cov khoom xyaw ua ke, tiv thaiv kev sib txuam, kev tiv thaiv kev sib txuam, kev tiv thaiv. Cov cuab yeej no yog qhov tseem ceeb hauv cov khoom xws li raug ncua, phoov, thiab cov tshuaj uas lub qhov ncauj.
6. Pseudopstejicity: Cellulose ntawm cov hniav ua kom pom kev coj cwj pwm pseudopastic cwj pwm, txhais tau tias nws viscosity txo qis nrog nce shear tus nqi. Cov cuab yeej no tso cai rau kev yooj yim dua, nqus tau, thiab kev siv ntawm cellulose glas-muaj cov khoom, thaum tseem muab cov thickness thiab ruaj khov thaum so.

Cov ntawv thov ntawm cellulose pos hniav:

1. Cov zaub mov thiab dej haus: cov hniav ntawm cov hniav yog siv dav ua qhov ua tuab, ruaj khov, thiab cov khoom noj khoom haus. Nws yog feem ntau pom hauv cov kua nplaum, hnav khaub ncaws, kua zaub, cov khoom noj siv mis, thiab ua kom meej, qhov ncauj, thiab txee rau khoom ruaj khov.
2. Kws Tshuaj Kho Mob: Hauv kev lag luam hauv chaw muag tshuaj, cellulose cov pos hniav yog siv los ua cov phau ntawv, ua tsis taus, thiab viscosity es ntawm ntsiav tshuaj tsim. Nws pab txhim kho cov ntsiav tshuaj cohesion, kev sib cais, thiab tso yeeb tshuaj profiles, ua rau muaj kev ua tau zoo thiab muaj kev sib luag ntawm cov ntaub ntawv ntawm cov tshuaj.
3. Cov khoom siv saib xyuas tus kheej: cov hniav ntawm cellulose tau sib xyaw ua cov tshuaj saib xyuas thiab cov tshuaj pleev ib ce, tshuaj txhuam hniav, tshuaj cream, thiab cream tsim. Nws pab ua cov tuab yaj ntaub, stabilizer, thiab zaj duab xis-ua tus neeg sawv cev, muab cov kev txawj ntse xav tau, thiab cov khoom siv zoo.
4. Kev siv cov ntaub ntawv: cov hniav ntawm cov cellulose yog siv hauv ntau cov ntawv thov xws li cov xim av, txheej ci, cov nplaum, thiab cov kua roj hmab, thiab tho kom zoo nkauj. Nws muab viscosity tswj, rheological hloov kho, thiab dej ceev cov khoom siv, txhim kho kev ua tau zoo thiab cov yam ntxwv ntawm cov ntaub ntawv no.

Cellulose cov pos hniav yog ib qho kev siv roj ntau ntau nrog cov kev siv hauv cov zaub mov, tshuaj kho mob, thiab kev lag luam tus kheej, thiab kev lag luam tus kheej. Nws cov yam ntxwv tshwj xeeb, suav nrog cov dej solubility, thickening, stabening, zaj duab xis-ua, ua rau nws muaj txiaj ntsig ntxiv hauv ntau cov qauv thiab cov khoom lag luam.
