Propylene Glycol Alginate PGA | 9005-37-2

(1) ʻO Colorcom Propylene glycol alginate (PGA) kahi ʻano hou o ka hoʻohui meaʻai maikaʻi loa. Hana ʻia ia e ka hana hohonu o ka waika alginic i unuhi ʻia mai ka limu maoli. He keʻokeʻo a i ʻole ka pauka melemele māmā ke ʻano. Hoʻohana pinepine ʻia e like me kahi mānoanoa, hoʻopaʻa a me ka emulsifier no nā huahana inu.
(2) Ma waho aʻe o kona hopena mānoanoa, loaʻa ka propylene glycol alginate i ke ʻano amphiphilic o nā surfactants, a me ka hiki ke emulsifying a me ka paʻa ʻana o ka pua, a he hopena hoʻomaha i nā colloids oily. ; No ka mea he hui non-ionic kēia huahana, paʻa loa ia i kekahi mau ion metala a ʻaʻole e paʻa a paʻa.
(3) He pauda fibrous keʻokeʻo keʻokeʻo keʻokeʻo keʻokeʻo a i ʻole ka pauda koʻikoʻi, aneane ʻaʻole ʻono a ʻono ʻole. Hiki ke hoʻoheheʻe ʻia i loko o ka wai a hoʻoheheʻe ʻia i ka hopena waika organik, akā ʻaʻole hiki ke hoʻoheheʻe ʻia i ka methanol, ethanol, benzene a me nā mea hoʻoheheʻe ʻē aʻe, akā hiki ke hoʻoheheʻe ʻia ka huahana esterified i loko o ka hopena ethanol me kahi maʻi o lalo o 60%. ʻO kona pH waiwai he 3-4 (1% aqueous solution), he maʻalahi ke komo i ka makū, lilo ia i ʻeleʻele i ka wā i wela ai i 55 °C, hiki ke carbonization ma 220 °C, a hiki i ka lehu ma 400 °C. ʻO 1.46 kona mānoanoa pili. ʻAʻole ia he gels a i ʻole precipitates i ka hopena acidic o ka pH 3-4.
(4) Loaʻa iā ia ka hiki ke pale aku i ka paʻakai, a paʻa i nā ion metala ʻē aʻe koe ke keleawe, chromium, hao (trivalent), ke kēpau, barium a me nā ion ʻē aʻe i paʻa ʻole.
