Propylene Glycol Alginate PGA | 9005-37-2

(1) Colorcom Propylene glycol alginate (PGA) ndi mtundu watsopano wazakudya zabwino zowonjezera. Amapangidwa ndi kukonzanso kwakuya kwa alginic acid yotengedwa kumadzi am'madzi am'madzi. Maonekedwe a ufa woyera kapena wopepuka wachikasu. Nthawi zambiri amagwiritsidwa ntchito ngati thickening, stabilizing ndi emulsifier kwa zakumwa zakumwa.
(2) Kuphatikiza pa kukhuthala kwake, propylene glycol alginate ili ndi mawonekedwe a amphiphilic a surfactants, komanso emulsifying mphamvu ndi kukhazikika kwa thovu, ndipo imakhala ndi mphamvu yokhazikika pamafuta amafuta. ; Chifukwa chakuti mankhwalawa ndi osagwirizana ndi ionic, amakhalanso okhazikika kwambiri pazitsulo zina zachitsulo ndipo sangalimbane ndi kugwa.
3 Ndi sungunuka m'madzi ndi kuchepetsa organic asidi njira, koma insoluble mu methanol, Mowa, benzene ndi zina zosungunulira organic, koma pang'ono esterified mankhwala akhoza kusungunuka Mowa njira ndi zili zosakwana 60%. Phindu lake la pH ndi 3-4 (1% yankho lamadzimadzi), ndilosavuta kuyamwa chinyezi, limasanduka bulauni likatenthedwa mpaka 55 ° C, carbonization imapezeka pa 220 ° C, ndipo phulusa limapezeka pa 400 ° C. Kuchulukana kwake ndi 1.46. Sakhala gels kapena kutsitsa mu acidic yankho la pH 3-4.
(4) Imatha kukana kutulutsa mchere, ndipo imakhala yokhazikika kwa ayoni ena achitsulo kupatula mkuwa, chromium, chitsulo (trivalent), lead, barium ndi ayoni ena omwe sakhazikika.
