Sodium alginate, tseem hu ua kelp ntawm cov pos hniav thiab alginate, yog ib hom ntawm cov saw zoo ib yam li polysaccharide muab rho tawm los ntawm kelp thiab seaweed los ntawm ntau yam kev hloov pauv ion (kev zom, lim, tshuaj dawb thiab calcification, decalcification, neutralization thiab transformation). Kab lus no hais txog kev siv sodium alginate' s kev lom zem uas yog ua kom tuab thiab zaj duab xis-tsim cov khoom.
（1） Ua lub ntsej muag tuab rau cov dej qab zib / cov khoom noj siv mis, sodium alginate muaj qhov tshwj xeeb zoo hauv kev ua kom nws cov kua nyeem tau zoo ua rau cov dej qab zib ntxiv rau cov dej muag muag thiab du, txhais tau tias nws tseem tuaj yeem tiv thaiv cov viscosity poob rau hauv cov txheej txheem ntawm cov khoom lag luam. Thaum siv sodium alginate ua cov tuab tuab, cov khoom lag luam nrog lub cev hnyav molecular yuav tsum tau siv kom deb li deb tau, thiab Ca yuav tsum muab ntxiv kom tsim nyog. Nws tuaj yeem txhim kho viscosity ntawm sodium alginate.
（2） Ua lub zog tswj cov dej khov thiab lwm cov dej txias, sodium alginate tuaj yeem ua rau dej khov thiab lwm yam dej txias ua rau cov tsos thiab tus tsw qab. Vim tias calcium alginate tuaj yeem ua cov roj thermal ruaj khov ua haujlwm, nws yuav tsis ua pob tawv (dej khov siv lead ua) thaum lub sijhawm kev thauj mus los thiab kev cia khoom. Nws yuav tsis ua rau khov khov deformation vim qhov kub hloov pauv. Nyob rau tib lub sijhawm, cov dej khov no tsis muaj qhov tsis hnov tsw thaum noj mov, uas tsis tsuas yog nthuav cov nqi nthuav tawm tab sis tseem txhim kho lub hauv paus melting, uas txhim kho qhov zoo thiab ua tau zoo ntawm cov khoom lag luam. Kev saj ntawm cov khoom yog du, muag heev thiab zoo. Tus nqi sib ntxiv yog tsawg, feem ntau 1-3 ‰ thiab 5-10 ‰ txawv teb chaws.
（3） Raws li lub stabilizer ntawm cov khoom noj siv mis thiab dej haus, khov mis khov nrog sodium alginate muaj qhov zoo saj, tsis muaj viscosity thiab tawv, viscosity thiab hysteresis thaum nplawm.
