Chikafu Giredhi Sodium Alginate | 9005-38-3

(1) Colorcom Sodium Alginate ndeye-chigadzirwa chekubviswa kweiodine uye mannitol kubva kubrown algae kelp kana Sargasso, iyo molecule inoumbwa ne β-D-mannuronic acid (β-D-mannuronic, M) uye α-L-guluronic acid (α-L-guluronic, G→) yakabatana ne (1). Iyo aqueous solution yesodium alginate ine high viscosity uye yakashandiswa sechikafu thickener, stabilizer, emulsifier, nezvimwe.
(2) Colorcom Sodium Alginate chikafu chisina chepfu uye chakabatanidzwa muU.S. Pharmacopoeia kare kare 1938. Colorcom Sodium alginate ine yakawanda ye -COO-, iyo inogona kuratidza maitiro e polyanionic mumushonga wemvura uye ine imwe adhesiveness, iyo inogona kushandiswa semutakuri wezvinodhaka wekurapa mucosal tissue.
(3) Pasi pemamiriro ezvinhu ane acidic, -COO- inoshandurwa kuva -COOH, dhigirii yeionization inoderera, hydrophilicity ye sodium alginate inoderera, molecular chain inoderera, uye kana pH inowedzera, boka -COOH rinoramba richiparadzanisa, hydrophilicity ye sodium alginate inowedzera uye molecular chain inotambanudza. Nokudaro, sodium alginate ine pH senitivity yakajeka.
(4) Colorcom Sodium alginate inogona kukurumidza kuumba gel pasi pemamiriro akapfava zvakanyanya. Kana paine cations dzakadai seCa2 + uye Sr2 +, Na+ paG unit inosangana neion exchange reaction ine divalent cations, uye maG mayuniti akaturikidzana kuti aite muchinjiko-yakabatana network chimiro, nokudaro ichigadzira hydrogel.
(5) Mamiriro akapfava e sodium alginate gel kuumbwa anogona kudzivirira kusashanda kwezvinhu zvinoshanda senge zvinodhaka zvinodhaka, mapuroteni, maseru uye ma enzymes. Nekuda kweaya akanakisa zvivakwa, sodium alginate yakashandiswa zvakanyanya muindasitiri yezvekudya uye mushonga.
(6) Colorcom Sodium alginate ichena kana kuti yakapfava yero poda, inenge isinganhuhwi uye haina kunaka. Sodium alginate inonyungudika mumvura, asi isinganyungudika muorganic solvents senge ethanol, ether, chloroform, nezvimwe.
