Hydroxyethyl selulose (HEC) ningirakamaro idafite amazi ya elegitoronike ya polymer hamwe ningingo nyinshi zikoreshwa mubikorwa byo gusiga amarangi.
1. Thickener
Hydroxyethyl selile ni umubyimba mwiza cyane. Irashobora kongera ubwiza bwirangi ikurura amazi mumuti wamazi kugirango yagure kandi ikore igisubizo cya colloidal. Ibi ntibifasha gusa gukumira irangi gutuza mugihe cyo kubika no gutwara, ariko kandi binanoza imiterere yacyo hamwe no guhagarika, byemeza uburinganire n'ubwuzuzanye bw'irangi.
2. Kugenzura imiterere
Hydroxyethyl selulose irashobora guhindura imiterere ya rheologiya irangi, ni ukuvuga guhindura imiterere yimiterere yayo kubiciro bitandukanye. Irashobora kugumana irangi kumurongo runaka muburyo buhagaze kugirango wirinde kugabanuka; kandi mugihe cyo gusaba, viscosity izagabanuka niyongera ryikigero cyogosha, cyoroshye mubwubatsi. Uyu mutungo ufasha kunoza ubwubatsi nuburyo bukora neza bwirangi.
3. Kubika amazi
Hydroxyethyl selulose ifite amazi meza. Irashobora gukumira neza guhumeka kwamazi vuba, bityo bikongerera igihe cyo kumisha irangi kandi bigatuma firime irangi igira umwanya uhagije wo kuringaniza no gukora firime mugihe cyo kumisha. Ibi ni ingenzi cyane cyane kumarangi ashingiye kumazi, kuko gutakaza amazi byihuse bishobora gutera ibibazo nka pinholes no guturika muri firime.
4. Ibintu bihamye kandi birwanya gutuza
Mu gusiga amarangi, cyane cyane sisitemu irimo pigment ikomeye kandi yuzuza, hydroxyethyl selulose irashobora gutanga ihagarikwa ryiza ryo guhagarara binyuze mubyimbye. Irashobora gukumira neza iyimurwa ryibara ryuzuye hamwe nuwuzuza, ikemeza neza irangi rimwe mugihe cyo kubika, bityo bigatuma ibara rihoraho hamwe nibikorwa bihamye.
5. Kunoza imiterere yo gukora firime
Hydroxyethyl selulose irashobora kuzamura imiterere ya firime yibara. Irashobora gukora firime imwe murwego rwo hejuru, igatezimbere uburinganire nuburinganire bwa firime. Byongeye kandi, hydroxyethyl selulose irashobora kandi kunoza anti-powder namazi yo kurwanya firime ya coating, bikongerera igihe kirekire nibiranga imitako.
6. Ibidukikije byangiza ibidukikije
Nkibyimbye bitari ionic, hydroxyethyl selulose ntabwo irimo ibyuma biremereye hamwe n’umuti wangiza, kandi byujuje ibisabwa byo kurengera ibidukikije. Ikoreshwa ryayo mu marangi ashingiye ku mazi arashobora kugabanya ibirimo ibinyabuzima bihindagurika (VOC), bifasha kugabanya umwanda ku bidukikije no kwangiza ubuzima bw’abantu.
Gukoresha hydroxyethyl selulose mu irangi ntibitezimbere gusa imiterere yumubiri nigikorwa cyo kubaka ibicuruzwa, ahubwo byujuje no kurengera ibidukikije nibisabwa n’inganda zigezweho. Nka nyongeramusaruro myinshi, igira uruhare runini mugushushanya no gukoresha amarangi.
