URUBANZA OYA.9004-62-0
Andi mazina: Cellulose ether, hydroxyethyl ether;Hydroxyethylcellulose;2-Hydroxyethyl selile;Hyetellose;
Hydroxyethyl selulose (HEC) ni umuhondo wera cyangwa umuhondo wera, utagira impumuro nziza, fibrous idafite uburozi cyangwa ifu ikomeye, byateguwe na etherification ya alkaline selulose na okiside ya Ethylene (cyangwa chloroethanol).Non-ionic soluble selulose ethers.Kubera ko HEC ifite ibintu byiza biranga umubyimba, guhagarika, gutatanya, kwigana, guhuza, gufata amashusho, kurinda ubushuhe no gutanga colloide ikingira, yakoreshejwe cyane mubushakashatsi bwa peteroli, gutwikira, kubaka, ubuvuzi n’imyenda, gukora impapuro, na macromolecules.Polymerisation hamwe nizindi nzego.Igipimo cya mesh 40 mesh ≥99%;
Hydroxyethyl Cellulose, ikoreshwa nkibibyimbye, birinda colloid, ibikoresho bisanzwe byo kubungabunga amazi hamwe na rheologiya ihindura porogaramu zitandukanye nko gusiga amarangi ashingiye ku mazi, ibice byubaka, ibikoresho bya peteroli byingenzi bya chimique nibicuruzwa byigenga.Bifite umubyimba mwiza, guhagarika, gutatanya, kwigana , gukora firime, kurinda amazi no gutanga ibintu birinda colloid.

Ibiranga imikorere
1).HEC irashobora gushonga mumazi ashyushye cyangwa akonje, ntabwo igwa mubushyuhe bwinshi cyangwa kubira, kuburyo ifite uburyo bwinshi bwo kwikemurira no kuranga ibishishwa, hamwe nubushuhe butari ubushyuhe;
2).Ntabwo ari ionic kandi irashobora kubana hamwe nandi moko menshi yandi mazi ashonga polymers, surfactants, nu munyu.Nibyimbye byiza bya colloidal birimo ibisubizo byinshi bya dielectric ibisubizo;
3).Ubushobozi bwo gufata amazi bukubye kabiri ubwa methyl selulose, kandi bufite gahunda nziza yo gutembera;
4).Ugereranije na methyl selulose izwi na hydroxypropyl methyl selulose, ubushobozi bwo gukwirakwiza HEC nububi cyane, ariko ubushobozi bwo kurinda colloid nubukomeye.
Hydroxyethyl Cellulose (HEC) Porogaramu
Umwanya wo gusaba
Ikoreshwa nkibikoresho bifatika, bikora hejuru yubutaka, imiti irinda colloidal, ikwirakwiza, emulisiferi na stabilisateur ikwirakwiza, nibindi. gukuramo no kuvura.
1. Mubisanzwe bikoreshwa nkibibyimbye, imiti ikingira, ibifata, stabilisateur ninyongeramusaruro mugutegura emulisiyo, geles, amavuta, amavuta yo kwisiga, ibikoresho byoza amaso, suppositions hamwe na tableti, kandi bikoreshwa nka hydrophilique gel na skeleton Ibikoresho, gutegura ubwoko bwa matrix imyiteguro irambye-irekura, kandi irashobora no gukoreshwa nka stabilisateur mubiryo.

3.HEC ikoreshwa nkigabanya umubyibuho ukabije nogutakaza amazi kumazi ashingiye kumazi hamwe no kurangiza.Ingaruka yibyibushye igaragara mumazi ya drine.Irashobora kandi gukoreshwa nkigikoresho cyo kugenzura ibihombo byamazi ya sima.Irashobora guhuzwa hamwe nicyuma cyinshi cya ion kugirango ikore gel.
4.Ibicuruzwa bikoreshwa mu kuvunika peteroli ishingiye kuri peteroli ishingiye kuri gel yamenagura amazi, polystirene na polyvinyl chloride hamwe nizindi zikwirakwiza polymeriki.Irashobora kandi gukoreshwa nka latx yibyibushye mu nganda zisiga amarangi, irwanya ubukonje bukabije mu nganda za elegitoroniki, anticagulant ya sima hamwe n’umukozi ushinzwe kubika amazi mu nganda zubaka.Inganda zubukorikori glaze hamwe nu menyo wamenyo.Ikoreshwa kandi cyane mu gucapa no gusiga irangi, imyenda, gukora impapuro, imiti, isuku, ibiryo, itabi, imiti yica udukoko hamwe n’ibikoresho bizimya umuriro.
5.HEC ikoreshwa nkibikoresho bikora hejuru, imiti irinda colloidal, stabilisateur ya emulion ya vinyl chloride, vinyl acetate nizindi emulisiyo, hamwe na latx yibyibushye, ikwirakwiza, stabilisateur ikwirakwiza, nibindi bikoreshwa cyane mubitambaro, fibre, irangi, gukora impapuro, kwisiga, imiti, imiti yica udukoko, nibindi. Ifite kandi byinshi mubushakashatsi bwamavuta ninganda.
6. Hydroxyethyl selulose ifite ibikorwa byubuso, kubyimba, guhagarikwa, gufatira, emulisation, gukora firime, gutatanya, kubika amazi no kurinda mumiti ya farumasi ikomeye kandi yuzuye.
