Propylene Glycol Alginate PGA | 9005-37-2

(1)I-Colorcom Propylene glycol alginate (PGA) iwuhlobo olusha lwesithasiselo sokudla esihle kakhulu. Yenziwa ngokucubungula okujulile kwe-alginic acid ekhishwe olwandle lwemvelo. Ukubukeka kuyimpushana emhlophe noma ephuzi ekhanyayo. Ivamise ukusetshenziswa njengokuqina, ukuzinzisa kanye ne-emulsifier emikhiqizweni yesiphuzo.
(2)Ngaphezu komphumela wayo wokujiya, i-propylene glycol alginate inesakhiwo se-amphiphilic sama-surfactants, kanye nekhono lokufaka i-emulsifying nokuzinza kwegwebu, futhi inomphumela wokuzinza kuma-oily colloid. ; Ngenxa yokuthi lo mkhiqizo uyinhlanganisela engeyona i-ionic, futhi uzinze kakhulu kwamanye ama-ion ensimbi futhi ngeke uqine futhi wenze imvula.
(3)Impushana emhlophe noma ephuzi ngokuphuzi noma emahhadla, cishe ayinaphunga futhi ayinambitheki. Iyancibilika emanzini futhi ihlambulule isixazululo se-asidi ephilayo, kodwa ayincibiliki ku-methanol, i-ethanol, i-benzene nezinye izinyibilikisi eziphilayo, kodwa umkhiqizo one-esterified ingxenye ungancibilika kusixazululo se-ethanol ngokuqukethwe okungaphansi kuka-60%. I-pH yayo ingu-3-4 (1% isixazululo esinamanzi), kulula ukumunca umswakama, iba nsundu uma ishiselwa ku-55 °C, i-carbonization ivela ku-220 °C, futhi umlotha uvela ku-400 °C. Ukuminyana kwayo okuhlobene ngu-1.46. Ayinajeli futhi ayinciphisi kwisisombululo esine-asidi se-pH 3-4.
(4)Inamandla okumelana nokuphuma kukasawoti ngaphandle, futhi izinzile kwamanye ama-ion ensimbi ngaphandle kwethusi, i-chromium, insimbi (i-trivalent), i-lead, i-barium namanye ama-ion angazinzile.
