Kunonosora Hydroxyethyl selulose

Ibisobanuro byaHydroxyethyl Cellulose. Dore incamake yuburyo bwo gutunganya HEC:

1. Guhitamo ibikoresho bito:

Igikorwa cyo gutunganya gitangirana no guhitamo selile nziza yo mu rwego rwo hejuru nkibikoresho fatizo. Cellulose irashobora gukomoka ahantu hatandukanye, nk'ibiti by'ibiti, imyenda y'ipamba, cyangwa ibindi bikoresho bishingiye ku bimera.

2. Kwezwa:

Ibikoresho bya selile mbisi bigenda bisukurwa kugirango bikureho umwanda nka lignin, hemicellulose, nibindi bikoresho bitari selile. Ubu buryo bwo kweza busanzwe bukubiyemo gukaraba, guhumanya, no kuvura imiti kugirango byongere isuku ya selile.

3. Kwiyongera:

Nyuma yo kwezwa, selile ihindurwa muburyo bwa chimique binyuze muri etherification kugirango yinjize amatsinda ya hydroxyethyl kumugongo wa selile, bituma habaho Hydroxyethyl Cellulose (HEC). Imyitwarire ya Etherification mubisanzwe ikubiyemo gukoresha hydroxide ya alkali yicyuma na okiside ya Ethylene cyangwa chilorohydrin ya Ethylene.

4. Kutabogama no Gukaraba:

Gukurikira etherification, reaction ivanze itabogamye kugirango ikure alkali irenze kandi ihindure pH. Ibicuruzwa bitagira aho bibogamiye noneho byogejwe neza kugirango bikureho imiti isigaye hamwe nibicuruzwa biva mubitekerezo.

5. Kuzunguruka no Kuma:

Igisubizo cyiza cya HEC cyayunguruwe kugirango gikureho ibice byose bisigaye cyangwa umwanda. Nyuma yo kuyungurura, igisubizo cya HEC kirashobora kwibandwaho, nibiba ngombwa, hanyuma ikuma kugirango ibone ifu yanyuma cyangwa ingano ya HEC.

6. Kugenzura ubuziranenge:

Muri gahunda yo kunonosora, ingamba zo kugenzura ubuziranenge zishyirwa mubikorwa kugirango habeho guhuza, kweza, no gukora ibicuruzwa bya HEC. Ibizamini byo kugenzura ubuziranenge bishobora kubamo gupima ubukonje, gusesengura uburemere bwa molekuline, kugena ibirimo ubuhehere, hamwe nisesengura ryumubiri n’imiti.

7. Gupakira no kubika:

Bimaze gutunganywa, ibicuruzwa bya HEC bipakirwa mubintu bikwiriye cyangwa imifuka yo kubika no gutwara. Gupakira neza bifasha kurinda HEC kwanduza, ubushuhe, nibindi bintu bidukikije bishobora kugira ingaruka kumiterere yabyo.

Porogaramu:

Hydroxyethyl Cellulose itunganijwe (HEC) isanga porogaramu nyinshi mubikorwa bitandukanye, harimo:

• Ubwubatsi: Byakoreshejwe nkibibyimbye, bihindura rheologiya, hamwe nububiko bwo kubika amazi mubicuruzwa bishingiye kuri sima, amarangi, ibifuniko, hamwe nibifatika.
• Kwitaho no kwisiga: Byakoreshejwe nkibibyimbye, stabilisateur, na firime yahoze mumavuta yo kwisiga, amavuta, shampo, nibindi bicuruzwa byita kumuntu.
• Imiti ya farumasi: Ikoreshwa nka binder, disintegrant, kandi igenzurwa-kurekura ibinini bya farumasi, capsules, hamwe no guhagarika umunwa.
• Ibiryo: Akazi nkibyimbye, emulisiferi, na stabilisateur mubicuruzwa byibiribwa nka sosi, imyambarire, nibikomoka ku mata.

Umwanzuro:

Kunonosora Hydroxyethyl Cellulose (HEC) bikubiyemo intambwe nyinshi zo kweza no guhindura ibikoresho bya selile mbisi, bikavamo polymer nyinshi kandi ikora cyane hamwe nibikorwa byinshi mubikorwa nkubwubatsi, ubuvuzi bwihariye, imiti, nibiribwa. Igikorwa cyo kunonosora cyemeza ubudahwema, ubuziranenge, nubwiza bwibicuruzwa bya HEC, bigafasha gukoreshwa muburyo butandukanye nibicuruzwa.
