Nyob rau tib lub sijhawm, nws kuj tseem tuaj yeem ua tus tsis muaj kev pab los pab cov ntsiav tshuaj tsis sib haum sai sai hauv kev tawm hauv plab thiab ua kom cov tshuaj tawm sai sai.
Cov Khoom Siv Tshuaj Tawm-Tso Tawm: Qee cov kws kho mob cellulose tuaj yeem siv raws li kev tso tawm cov tshuaj tso tawm los ntawm kev tsim cov khoom gel, li ntev lub sijhawm ua yeeb tshuaj. Cov cuab yeej no tau siv dav hauv cov tshuaj tso tawm thiab ua yeeb yam ntev ntev, xws li tshuaj kho mob thiab txhim kho cov neeg mob txoj kev ua kom cov tshuaj lom neeg.
Cov txheej tiv thaiv tiv thaiv: Cov neeg muaj kev pab cuam cellulose tseem siv rau hauv cov ntsiav tshuaj, uas tuaj yeem tiv thaiv noo noo thiab oxidation, thiab tseem tuaj yeem txhim kho cov tsos thiab saj ntawm cov tshuaj.
3. Daim ntawv thov hauv kev lag luam khoom noj khoom haus
Nyob rau hauv kev lag luam khoom noj khoom haus, cov neeg muaj kev hais ua ke yog siv los ua cov thickeners, stabilizers thiab emulsifiers, uas tuaj yeem txhim kho cov saj, kev ua haujlwm thiab lub zog txee ntawm cov zaub mov.
Thickeners: Cov kev hais daws cellulose tuaj yeem tsim cov kev daws teeb meem ruaj khov hauv dej thiab siv raws li thickenters los muab cov zaub mov zoo sib xws. Qhov no yog qhov tseem ceeb tshwj xeeb hauv cov khoom xws li cov khoom ua kom zoo, cov khoom noj siv mis nyuj, thiab mis nyuj khov, uas tuaj yeem muab cov khoom noj zoo nkauj thiab du.
Cov neeg siv hluav taws xob thiab emulsifiers: cov neeg muaj kev hais tiv thaiv cellulose tuaj yeem tiv thaiv kev sib cais ntawm cov roj thiab cov khoom noj thiab ua kom cov yam ntxwv sib luag thiab ruaj khov ntawm cov khoom tiav. Piv txwv li, hauv cov khaub noom nyias nyias thiab haus dej haus, nws pab ua kom cov sib tov sib xyaw.
Thermal gelation: qee cov qauv cellulose tuaj yeem tsim cov khoom siv gel thaum cua sov, nce cov dej viscosity thiab dej muaj peev xwm txhim kho nws cov tshiab. Cov cuab yeej no yog ib qho tseem ceeb tshwj xeeb hauv cov zaub mov ci, uas tuaj yeem ua kom cov khoom noo.
4. Daim ntawv thov hauv kev lag luam tshuaj pleev ib ce
Nyob rau hauv cov tshuaj pleev ib ce kev lag luam, cellulose cov neeg muaj kev hais ua ke tau siv nyob rau hauv cov tshuaj pleev, tshuaj txhuam hniav, cov tshuaj txhuam hniav, cov tshuaj txhuam hniav, emulsifiers thiab zaj duab xis tsim.
