Hydroxyethyl selulose ni polymer idafite amazi ya elegitoronike ikozwe muri selile, ibintu bisanzwe bya polymer, binyuze muburyo bwa chimique. Nibintu byera cyangwa umuhondo, bidafite impumuro nziza kandi idafite uburyohe bwifu, bishobora gushonga mumazi akonje ndetse namazi ashyushye, kandi umuvuduko wo kwiyongera ugenda wiyongera hamwe nubushyuhe. Mubisanzwe, ntigishobora gukemuka mumashanyarazi menshi. Ikoreshwa nkibyimbye na stabilisateur mu irangi rya latex. Biroroshye gutatanya mumazi akonje afite pH agaciro kari munsi cyangwa kangana na 7, ariko biroroshye guhuriza hamwe mumazi ya alkaline, kubwibyo rero muri rusange byateguwe hakiri kare kugirango bikoreshwe nyuma, cyangwa amazi ya aside idakomeye cyangwa igisubizo kama gikozwe mubitotsi. , kandi irashobora kandi kuvangwa nizindi granulaire Ibigize byumye bivanze hamwe.
Ibiranga hydroxyethyl selulose:
HEC irashobora gushonga mumazi ashyushye cyangwa akonje, kandi ntigwa kugwa mubushyuhe bwinshi cyangwa kubira, ibyo bigatuma igira ibintu byinshi byo gukemuka no kuranga ibibyimba, hamwe nubushuhe butari ubushyuhe.
Irashobora kubana hamwe nandi moko menshi yandi mashanyarazi ya elegitoronike, amazi, hamwe nu munyu, kandi ni umubyimba mwiza wa colloidal kubisubizo birimo electrolytite yibanda cyane.
Ubushobozi bwo gufata amazi bukubye kabiri ubwa methyl selulose, kandi bufite gahunda nziza yo gutembera.
Ugereranije na methyl selulose izwi na hydroxypropyl methyl selulose, ubushobozi bwo gukwirakwiza HEC nububi, ariko ubushobozi bwo gukingira colloid nabwo bukomeye.
Ubwubatsi buhebuje; ifite ibyiza byo kuzigama umurimo, ntabwo byoroshye gutonyanga, kurwanya-sag, kurwanya anti-splash, nibindi.
Guhuza neza na surfactants zitandukanye hamwe nuburinzi bukoreshwa mumarangi ya latex.
Ububiko bwo kubika neza burahagaze, bushobora kubuza hydroxyethyl selulose muri rusange kugabanya ubukana bwirangi rya latex mugihe cyo kubika kubera kubora kwa enzymes.
