Sodium alginate, also known as seaweed glue, is a white or light yellow particle or powder, almost odorless and tasteless. It is a high viscosity polymer compound and a typical hydrophilic sol. It is widely used in many industries such as food, medicine, printing and dyeing because of its stability, thickening and emulsification, hydration and gelation.
Hauv kev luam ntawv thiab zas xim kev lag luam, sodium alginate tau siv los ua tshuaj pleev xim, uas zoo dua li cov nplej, hmoov txhuv nplej siab thiab lwm qhov ntau thiab tsawg. Cov ntawv luam tawm muaj cov qauv zoo nkauj, kab meej, muab xim siab, xim tsis sib xws, thiab ua kom zoo dua qub thiab yas. Seaweed kua nplaum yog qhov loj tshaj plaws hauv kev luam ntawv niaj hnub thiab zas xim. Nws tau siv dav hauv kev luam tawm ntawm paj rwb, ntaub plaub, txhob lo lo ntxhuav, nylon thiab lwm yam ntaub, tshwj xeeb hauv kev npaj ntawm ncoo luam ntawv muab tshuaj txhuam. Nws kuj tseem tuaj yeem siv los ua cov khoom siv warp, uas tuaj yeem tsis tsuas yog txuag ntau cov nplej, tab sis kuj tseem ua rau warp fiber ntau lo lo dawb, txhuam kev tiv taus thiab tsawg kawg qhov tawg tawg, yog li txhawm rau txhim kho kev ua haujlwm zoo, uas muaj txiaj ntsig zoo rau ob qho tib si paj rwb fiber thiab hluavtaws fiber.
Ib qho ntxiv, sodium alginate kuj tseem siv hauv kev ua papermaking, kev lag luam tshuaj txhua hnub, pov tseg, cov khoom siv hluav taws xob ntawm cov tawv nqaij, ntses thiab cw nuv ntses, txiv hmab txiv ntoo tsob ntoo tua kab, tshuaj tso tawm tus neeg sawv cev, polymer agglutination thiab sedimentation tus neeg sawv cev rau kev kho dej, thiab lwm yam.
