HEC selile ni umubyimba mwiza.

Hydroxyethylcellulose (HEC) ni umubyimba utandukanye kandi ukora neza ukoreshwa cyane mubikorwa bitandukanye. Uru ruganda rukomoka kuri selile, polymer karemano iboneka cyane murukuta rwibimera. Imiterere yihariye ya HEC ituma biba byiza kubyimbye ibicuruzwa bitandukanye, uhereye kubicuruzwa byumuntu ku giti cye kugeza mubikorwa byinganda.

Incamake ya Cellulose

Cellulose ni karubone nziza igizwe n'iminyururu igororotse ya molekile ya glucose ihujwe na β-1,4-glycosidic. Nibintu nyamukuru byubaka urukuta rwibihingwa, bitanga ubukana nimbaraga zingirabuzimafatizo. Nyamara, imiterere kavukire ntishobora gukemuka kandi ifite imikorere mike kubikorwa bimwe.

ibikomoka kuri selile

Kugirango tuzamure imikorere ya selile, ibikomokaho bitandukanye byashizwe hamwe muguhindura imiterere. Imwe mu nkomoko ni hydroxyethyl selulose (HEC), aho amatsinda ya hydroxyethyl yinjizwa mu mugongo wa selile. Ihinduka ritanga HEC imiterere yihariye, ituma ishonga mumazi kandi ikora neza nkibyimbye.

Ibiranga HEC

Gukemura

Kimwe mu bintu by'ingenzi biranga HEC ni amazi yacyo. Bitandukanye na selile naturelose, HEC ishonga byoroshye mumazi, bigatanga igisubizo kiboneye. Uku kwikemurira byoroshye kwinjiza muburyo butandukanye.

Imiterere ya Rheologiya

HEC igaragaza imyitwarire ya pseudoplastique cyangwa shear-inanura, bivuze ko ububobere bwayo bugabanuka mugihe cyogosha kandi bikongera kwiyongera nyuma yo guhangayika. Iyi rheologiya ni ingenzi kubisabwa bisaba koroshya gukwirakwiza cyangwa gusuka, nko gukora amarangi, ibifata hamwe nibicuruzwa byawe bwite.

pH ituze

HEC ihamye hejuru ya pH yagutse, bigatuma ikoreshwa muburyo bwa acide, butabogamye na alkaline. Ubu buryo bwinshi bwagize uruhare runini mu nganda zitandukanye zirimo kwisiga, imiti n’ibiribwa.

Porogaramu ya HEC

ibicuruzwa byita ku muntu

Shampo na Conditions: HEC ikoreshwa mugukomeza ibicuruzwa byita kumisatsi, bitanga ubwiza bwiza no kunoza imiterere rusange.

Amavuta n'amavuta: Muburyo bwo kwita ku ruhu, HEC ifasha kugera ku cyifuzo cyifuzwa kandi ikongerera ikwirakwizwa rya cream n'amavuta yo kwisiga.

Amenyo yinyo: Imyitwarire ya pseudoplastique yorohereza amenyo yinyo yemerera gukwirakwiza byoroshye no gukwirakwira mugihe cyo koza.

Irangi

Irangi rya Latex: HEC ifasha kongera ubukonje no gutuza kw'irangi rya latex, ikemeza no gukoreshwa hejuru.

Ibifatika: Mubisobanuro bifatika, HEC ifasha kugenzura ububobere no kunoza imikoranire.

ibiyobyabwenge

Guhagarika umunwa: HEC ikoreshwa muguhagarika umunwa kugirango itange uburyo buhamye kandi bushimishije kumiti.

Gele yibanze: Gukomera kwa HEC mumazi bituma bikwiranye no gukora gele yibanze, bikoroha kubishyira no kuyakira.

inganda z'ibiribwa

Isosi n'imyambarire: HEC ikoreshwa mu kubyibuha isosi no kwambara, kunoza imiterere no kunwa.

Ibicuruzwa bitetse: Muburyo bumwe bwo guteka, HEC ifasha kubyibuha amavuta.

Umusaruro no kugenzura ubuziranenge

synthesis

HEC isanzwe ikorwa na etherification ya selile hamwe na okiside ya Ethylene mugihe cyagenwe. Urwego rwo gusimbuza (DS) rwitsinda rya hydroxyethyl rushobora guhinduka mugihe cya synthesis, bityo bikagira ingaruka kumikorere ya nyuma ya HEC.

QC

Ingamba zo kugenzura ubuziranenge ningirakamaro kugirango harebwe imikorere ihamye ya HEC mubikorwa bitandukanye. Ibipimo nkuburemere bwa molekile, urugero rwo gusimbuza nubuziranenge bikurikiranwa neza mugihe cyibikorwa.

ibidukikije

Kimwe n’ibintu byose bivangwa n’imiti, ibidukikije ni ngombwa. HEC ikomoka kuri selile kandi isanzwe ibora cyane kuruta ibibyimba bimwe na bimwe. Nyamara, ni ngombwa gusuzuma ingaruka rusange z’ibidukikije ku musaruro wazo no gukoresha mu bikorwa bitandukanye.

mu gusoza

Muri make, hydroxyethylcellulose (HEC) igaragara nkibyimbye bifatika kandi bihindagurika hamwe nibisabwa mubikorwa byinshi. Imiterere yihariye, harimo gukemura amazi, imyitwarire ya rheologiya hamwe na pH itajegajega, bituma iba ingirakamaro muburyo butandukanye bwo gukora ibicuruzwa. Mugihe inganda zikomeje gushakisha ubundi buryo bwangiza ibidukikije, imitungo ya HEC ibora ikomoka kuri selile yibihingwa bituma ihitamo rirambye mubikorwa bitandukanye. Gukomeza ubushakashatsi no guhanga udushya dukomoka kuri selile nka HEC birashobora kuganisha ku gutera imbere, gutanga imikorere myiza no kugabanya ingaruka z’ibidukikije.
