Propylene Glycol Alginate PGA | 9005-37-2

(1) I-Colorcom Propylene glycol alginate (PGA) luhlobo olutsha lwezongezo zokutya ezigqwesileyo. Yenziwe ngokucutshungulwa nzulu kwe-alginic acid ekhutshwe kwi-seaweed yendalo. Imbonakalo ngumgubo omhlophe okanye otyheli okhanyayo. Ihlala isetyenziselwa ukujiya, ukuzinzisa kunye ne-emulsifier kwiimveliso zesiselo.
(2) Ukongeza kwisiphumo sayo sokuqina, ipropylene glycol alginate inesakhiwo se-amphiphilic ye-surfactants, kunye nekhono lokumisa kunye nokuzinza kwe-foam, kwaye inefuthe lokuzinzisa kwi-oily colloids. ; Ngenxa yokuba le mveliso iyikhompawundi engeyiyo i-ionic, iphinda izinze kakhulu kwezinye ii-ion zetsimbi kwaye aziyi kuqina kwaye ziqhube.
(3)Umgubo omhlophe okanye otyheli-mhlophe kancinci okanye umgubo orhabaxa, phantse awunavumba kwaye awunancasa. I-soluble emanzini kwaye i-dilute organic acid solution, kodwa ayinyibiliki kwi-methanol, i-ethanol, i-benzene kunye nezinye izinyibilikisi ze-organic, kodwa imveliso ye-esterified inxalenye inganyibilika kwisisombululo se-ethanol esinomxholo ongaphantsi kwe-60%. Ixabiso layo le-pH yi-3-4 (i-1% yesisombululo se-aqueous), kulula ukufunxa ukufuma, ijika ibe mdaka xa ishushu kwi-55 °C, i-carbonization iyenzeka kwi-220 °C, kwaye uthuthu lwenzeka kwi-400 °C. Ubuninzi bayo obusondeleyo yi-1.46. Ayina gel okanye i-precipitates kwisisombululo se-acidic se-pH 3-4.
(4)Inamandla okuxhathisa i-salting ngaphandle, kwaye izinzile kwezinye i-ion zetsimbi ngaphandle kobhedu, i-chromium, isinyithi (i-trivalent), i-lead, i-barium kunye nezinye i-ion ezingazinzanga.
