1. Ibyiza bya hydroxyethyl selulose
Iki gicuruzwa cyera cyangwa cyoroshye cyumuhondo 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;umuvuduko wo gutwika 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. HEC irashonga mumazi ashyushye cyangwa mumazi akonje, kandi ntigwa kugwa mubushyuhe bwinshi cyangwa kubira, bigatuma igira uburyo bwinshi bwo gukemuka, ibiranga ubukonje hamwe nubushyuhe butari ubushyuhe.
2. Ntabwo ari ionic kandi irashobora kubana hamwe nandi moko menshi yandi mazi ashonga amazi, surfactants, nu munyu.Nibyimbye byiza bya colloidal kubyibushye cyane bya electrolyte ibisubizo.
3. Ubushobozi bwo gufata amazi bwikubye kabiri ubwa methyl selulose, kandi bufite gahunda nziza yo gutembera.
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, suppositions na tableti, kandi bigakoreshwa nka geles hydrophilique, ibikoresho bya skeleton, Irashobora gukoreshwa mugutegura matrix- andika imyiteguro irambye-irekura, kandi irashobora no gukoreshwa nka stabilisateur mubiryo.
