Physicochemical Properties
- Dej Solubility: Soluble nyob rau hauv dej ntawm chav tsev kub, yielding ib tug pob tshab aqueous tov uas tsis pom impurities. Tsis yog - lom, tsis muaj mob, nyab xeeb thiab ib puag ncig tus phooj ywg, ua tau raws li qhov yuav tsum tau muaj ntawm cov qauv kev nyab xeeb kev sib cuag zaub mov.
- Tshuaj Resistance: Nyob rau hauv chav tsev kub, cov tshuaj aqueous tuav ib tug ruaj khov pH nqi ntawm 5-7 thiab zoo ib yam viscosity. Nws muaj kev tiv thaiv siab rau cov acids tsis muaj zog, tsis muaj zog hauv paus (tsawg dua lossis sib npaug li 5% concentration), thiab cov organic solvents (xws li, esters, ketones, cawv ntau dua, hydrocarbons) tsis ua rau nag lossis daus, viscosity fluctuation lossis tshuaj degradation. Tsis tas li ntawd, nws muaj cov roj ua haujlwm zoo heev, tsis muaj qhov o lossis tawg thaum sib cuag nrog cov zaub los yog cov roj ntxhia.
- Miscibility: Ua tau nrog cov hmoov txhuv nplej siab, cov khoom siv hluavtaws (xws li, PVA, polyacrylic resin), cellulose derivatives (xws li, CMC, HPMC), thiab ntau yam surfactants, tsim cov khoom sib tov ruaj khov. Cov stratification me ntsis yuav tshwm sim tom qab ntev - lub sij hawm cia, uas tuaj yeem rov qab mus rau qhov sib xws los ntawm kev co maj mam.
