1. Intangiriro
Hydroxyethyl Cellulose (HEC) ni ibikoresho bidafite amazi ya elegitoronike ya polymer yakozwe na reaction ya selile selile na okiside ya Ethylene. Bitewe nuburyo budasanzwe bwumubiri nubumashini, nkamazi meza yo gukama, kubyimba, gukora firime, gutuza no guhagarika ubushobozi, HEC yakoreshejwe cyane mubikorwa byimiti.
2. Imirima yo gusaba
Inganda zo gutwikira
Mu nganda zitwikiriye, HEC ikoreshwa cyane cyane mubyimbye na rheologiya. Mu bikorwa byayo harimo:
Kunoza ubudahwema hamwe na rheologiya yububiko: HEC irashobora kugenzura neza imyitwarire ya rheologiya yimyenda, kunoza imikorere yubwubatsi, gutuma igifuniko kidashobora kugabanuka, kandi byoroshye gukaraba no kuzunguruka.
Gutezimbere igifuniko: HEC ifite amazi meza cyane yo gukingira no gukingira colloidal, bishobora gukumira neza imyanda ya pigment no gutondekanya igipfundikizo, kandi bikazamura ububiko bwububiko.
Kunoza imiterere-yimiterere ya firime yimyenda: HEC irashobora gukora firime imwe mugihe cyumye cyo gutwikisha, kunoza imbaraga zo gutwikira hamwe nuburabyo bwa coating.
Inganda zikomoka kuri peteroli
Mubikorwa byo gucukura peteroli no kubyara amavuta, HEC ikoreshwa cyane cyane nk'inyongera yo gucukura amazi no kuvunika. Mu bikorwa byayo harimo:
Kubyimba no guhagarikwa: HEC irashobora kongera cyane ubwiza bwamazi yo gucukura no kuvunika amazi, guhagarika neza gutema imyanda hamwe na pompants, kwirinda iriba ryangirika no kongera umusaruro wamavuta.
Igenzura rya Filtration: HEC irashobora kugenzura neza igihombo cyo kuyungurura amazi yo gucukura, kugabanya umwanda w’imiterere, no kunoza ituze n’ubushobozi bwo gukora amariba ya peteroli.
Guhindura imiterere: HEC irashobora kunonosora imvugo yo gutobora amazi no kuvunika, kongera ubushobozi bwayo bwo gutwara umucanga, no kunoza imikorere ningaruka zimikorere yamenetse.
Inganda zubaka
Mu nganda zubaka, HEC ikoreshwa kenshi muri sima ya marima, ibicuruzwa bya gypsumu hamwe n irangi rya latex. Ibikorwa byayo byingenzi birimo:
Kubyimba no gufata amazi: HEC irashobora kunoza ubudahangarwa bwa minisiteri na gypsumu, ikongera imikorere mu gihe cyo kubaka, kandi ikazamura amazi yayo, ikabuza gutakaza amazi, kandi ikongerera imbaraga ubumwe.
Kurwanya kugabanuka: Mu irangi rya latex, HEC irashobora kubuza irangi kugabanuka hejuru yuburebure, kugumana umwenda, no kuzamura ubwubatsi.
Kuzamura umubano mwiza: HEC irashobora kunoza isano iri hagati ya sima na sima, byongera imbaraga nigihe kirekire cyibikoresho.
2.4 Inganda zikora imiti ya buri munsi
Imikoreshereze yingenzi ya HEC mubicuruzwa bya chimique bya buri munsi harimo gukoreshwa nkibibyimbye, stabilisateur na emulisiferi yo kumesa, shampo, amavuta yo kwisiga. Mu bikorwa byayo harimo:
Kubyimba: HEC irashobora kongera cyane ubwiza bwibicuruzwa bya chimique ya buri munsi, bigatuma ibicuruzwa bitoshye kandi byiza gukoresha.
Gutezimbere: HEC ifite amazi meza yo gukingira no kurinda colloid, irashobora guhagarika sisitemu ya emulisile, ikarinda amavuta n’amazi, kandi ikongerera igihe cyibicuruzwa.
Guhagarikwa: HEC irashobora guhagarika ibice byiza, kunoza ikwirakwizwa nuburinganire bwibicuruzwa, no kunoza isura nuburyo.
2.5 Inganda zimiti
Mu nganda zimiti, HEC ikoreshwa cyane cyane nka binder kandi irekura-irekura, imiti ya gelling na emulisiferi kubinini. Mu bikorwa byayo harimo:
Guhambira: HEC irashobora guhuza neza ibice byibiyobyabwenge no kunoza imbaraga za mashini no gusenya imikorere yibinini.
Irekurwa rirambye: HEC irashobora guhindura igipimo cyo kurekura ibiyobyabwenge, ikagera ku ngaruka zihoraho cyangwa zigenzurwa, kandi ikanoza imikorere y’ibiyobyabwenge no kubahiriza abarwayi.
Gel na emulisifike: HEC irashobora gukora gel imwe cyangwa emulsiyo muguhindura ibiyobyabwenge, bigateza imbere uburyohe nibiryo byibiyobyabwenge.
3. Ibyiza n'ibiranga
3.1 Ibyiza byo kubyimba hamwe na rheologiya
HEC ifite ubushobozi buhebuje bwo guhindura no kuvugurura imvugo, ishobora kongera cyane ubwiza bwibisubizo byamazi, bigatuma bitwara nkamazi ya pseudoplastique ku gipimo gito cyogosha hamwe n’amazi ya Newtonian ku gipimo kinini. Ibi birabasha kuzuza ibisabwa bya rheologiya mubikorwa bitandukanye byinganda.
3.2 Guhagarara no guhuza
HEC ifite imiti ihamye, irashobora gukomeza imikorere ihamye ya pH yagutse, kandi igahuzwa nimiti itandukanye hamwe nuwashonga. Ibi birayifasha kugumana umubyimba uhamye no gutuza muri sisitemu yimiti igoye.
3.3 Kurengera ibidukikije n'umutekano
HEC ikozwe muri selile isanzwe, ifite ibinyabuzima byiza kandi byangiza ibidukikije. Muri icyo gihe, HEC ntabwo ari uburozi kandi ntacyo itwaye, kandi irakwiriye ku bicuruzwa bya shimi na farumasi bya buri munsi bifite umutekano muke.
Hydroxyethyl selulose (HEC) ifite uburyo bwinshi bwo gukoresha kandi igira uruhare runini mu nganda zikora imiti. Ubwiza bwayo buhebuje, imiterere ya rheologiya, ituze hamwe nubwuzuzanye bituma iba inyongeramusaruro yinganda nyinshi nka coatings, peteroli, ubwubatsi, imiti ya buri munsi na farumasi. Hamwe niterambere ryikoranabuhanga hamwe nimpinduka zikenewe ku isoko, ibyifuzo bya HEC bizaba binini.
