Propylene Glycol Alginate PGA | 9005-37-2

(1) Colorcom Propylene glycol alginate (PGA) yog ib hom khoom noj khoom haus zoo tshaj plaws. Nws yog tsim los ntawm kev sib sib zog nqus ntawm alginic acid muab rho tawm los ntawm ntuj seaweed. Cov tsos yog dawb los yog lub teeb daj hmoov. Nws feem ntau yog siv los ua thickening, stabilizing thiab emulsifier rau cov khoom haus.
(2) Ntxiv rau nws cov nyhuv thickening, propylene glycol alginate muaj cov qauv amphiphilic ntawm surfactants, nrog rau emulsifying muaj peev xwm thiab ua npuas ncauj stability, thiab muaj ib tug stabilizing nyhuv ntawm oily colloids. ; Vim tias cov khoom no yog cov khoom siv tsis yog-ionic, nws kuj tseem ruaj khov rau qee cov hlau ions thiab yuav tsis khov thiab nag lossis daus.
(3) Dawb los yog me ntsis daj-dawb fibrous hmoov los yog coarse hmoov, yuav luag odorless thiab tasteless. Nws yog soluble nyob rau hauv dej thiab dilute organic acid tov, tab sis insoluble nyob rau hauv methanol, ethanol, benzene thiab lwm yam organic solvents, tab sis ib nrab esterified khoom yuav yaj nyob rau hauv ethanol tov nrog ib tug tsawg tshaj li 60%. Nws tus nqi pH yog 3-4 (1% aqueous tov), ​​nws yog ib qho yooj yim kom nqus noo noo, nws tig xim av thaum rhuab mus rau 55 ° C, carbonization tshwm sim ntawm 220 ° C, thiab ashing tshwm sim ntawm 400 ° C. Nws tus txheeb ze ntom ntom yog 1.46. Nws tsis yog gels los yog precipitates nyob rau hauv acidic tov ntawm pH 3-4.
(4) Nws muaj peev xwm tiv taus salting tawm, thiab ruaj khov rau lwm cov hlau ions tshwj tsis yog tooj liab, chromium, hlau (trivalent), txhuas, barium thiab lwm yam ions uas tsis ruaj khov.
