Cellulose Gum - Cov Khoom Siv Khoom Noj

Cellulose cov pos hniav, tseem hu ua carboxymethylcellulose (CMC), yog hloov kho cellulose polymer muab los ntawm cov nroj tsuag. Nws yog feem ntau siv los ua cov khoom noj khoom haus vim nws cov khoom siv ntau yam ua tus neeg ua kom tuab, stabilizer, thiab emulsifier. Lub hauv paus ntsiab lus ntawm cellulose pos hniav nyob rau hauv cov ntsiab lus ntawm cov khoom xyaw yog cov nroj tsuag fibers. Nov yog cov ntsiab lus tseem ceeb:

1. Ntoo Pulp:
   • Cellulose cov pos hniav feem ntau yog muab los ntawm cov ntoo pulp, uas yog feem ntau tau los ntawm cov ntoo softwood lossis ntoo tawv ntoo. Cov cellulose fibers nyob rau hauv ntoo pulp raug hloov kho cov txheej txheem los tsim carboxymethylcellulose.
2. Cotton Linters:
   • Paj rwb linters, luv fibers txuas nrog paj rwb noob tom qab ginning, yog lwm qhov chaw ntawm cellulose pos hniav. Cov cellulose tau muab rho tawm los ntawm cov fibers thiab tom qab ntawd hloov kho los tsim carboxymethylcellulose.
3. Microbial Fermentation:
   • Qee zaum, cov pos hniav cellulose tuaj yeem tsim los ntawm microbial fermentation siv qee cov kab mob. Cov kab mob microorganisms raug tsim los tsim cov cellulose, uas tom qab ntawd hloov kho los tsim carboxymethylcellulose.
4. Sustainable thiab Renewable Sources:
   • Muaj kev txaus siab ntxiv rau kev tau txais cellulose los ntawm cov khoom siv tau ruaj khov thiab txuas ntxiv mus. Qhov no suav nrog kev tshawb nrhiav lwm qhov chaw cog qoob loo rau cov pos hniav cellulose, xws li cov khoom seem ua liaj ua teb lossis cov qoob loo uas tsis yog zaub mov.
5. Regenerated Cellulose:
   • Cellulose cov pos hniav kuj tuaj yeem muab tau los ntawm cov cellulose regenerated, uas yog tsim los ntawm dissolving cellulose nyob rau hauv ib tug hnyav thiab ces regenerating nws mus rau hauv ib tug usable daim ntawv. Txoj kev no tso cai rau kev tswj hwm ntau dua ntawm cov khoom ntawm cov pos hniav cellulose.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias thaum cov pos hniav cellulose tau muab los ntawm cov nroj tsuag, cov txheej txheem hloov kho muaj cov tshuaj tiv thaiv los qhia cov carboxymethyl pawg. Qhov kev hloov kho no txhim kho cov dej-solubility thiab kev ua haujlwm ntawm cov pos hniav cellulose, ua rau nws haum rau ntau yam kev siv hauv kev lag luam khoom noj.

Hauv cov khoom kawg, cov pos hniav cellulose feem ntau tshwm sim hauv me me thiab ua haujlwm tshwj xeeb xws li thickening, stabilizing, thiab txhim kho kev ntxhib los mos. Nws yog dav siv nyob rau hauv ntau yam khoom noj, nrog rau cov kua ntsw, hnav khaub ncaws, khoom noj siv mis, ci, thiab lwm yam. Cov nroj tsuag-derived xwm ntawm cellulose cov pos hniav ua ke nrog cov neeg siv khoom nyiam rau cov khoom xyaw ntuj thiab cov nroj tsuag hauv kev lag luam zaub mov.
