1. Ibyiza bya hydroxyethyl selulose
Iki gicuruzwa cyera cyangwa cyoroshye cyumuhondo kitagira impumuro nziza kandi byoroshye gutemba, igipimo cya mesh 40 mesh ≥99%; koroshya ubushyuhe: 135-140 ° C; ubucucike bugaragara: 0.35-0.61g / ml; ubushyuhe bwo kubora: 205-210 ° C; gutwika umuvuduko Buhoro; ubushyuhe buringaniye: 23 ° C; 6% kuri 50% rh, 29% kuri 84% rh.
Irashobora gushonga mumazi akonje namazi ashyushye, kandi mubisanzwe ntishobora gushonga mumashanyarazi menshi. Ubukonje burahinduka gato murwego rwa PH agaciro 2-12, ariko ububobere bugabanuka kurenza iyi ntera.
2. Ibintu byingenzi
Nka surfactant itari ionic,hydroxyethyl selileifite imitungo ikurikira usibye kubyimba, guhagarika, guhambira, kureremba, gukora firime, gutatanya, kubika amazi no gutanga colloid ikingira:
1.
2. Ntabwo ari ionic kandi irashobora kubana hamwe nandi moko menshi yandi mazi ashonga polymers, surfactants, nu munyu. Nibyimbye byiza bya colloidal kubyibushye cyane bya electrolyte ibisubizo.
3. Ubushobozi bwo gufata amazi bukubye kabiri ubwa methyl selile, kandi bufite uburyo bwiza bwo gutembera neza.
4. Ugereranije na methyl selulose izwi na hydroxypropyl methyl selulose, HEC ifite ubushobozi bwo gukwirakwiza nabi, ariko ubushobozi bukomeye bwo kurinda colloid.
3. Gukoresha hydroxyethyl selulose
Mubisanzwe bikoreshwa nkibibyimbye, ibikoresho birinda, ibifata, stabilisateur ninyongeramusaruro mugutegura emulisiyo, jellies, amavuta, amavuta yo kwisiga, koza amaso, suppositori na tableti, kandi bigakoreshwa nka gele hydrophilique, ibikoresho bya skeleton, Irashobora gukoreshwa mugutegura matrix- andika imyiteguro irambye-irekura, kandi irashobora no gukoreshwa nka stabilisateur mubiryo.
