Hydroxyethyl Cellulose (HEC) nikintu gisanzwe kitari ionic amazi-gashonga polymer hamwe nububyimbye buhebuje, kubika amazi, hamwe nibikorwa bya firime. Kubwibyo, ikoreshwa cyane mubitambaro, amarangi ya latex, hamwe na kole. Ibifatika hamwe nizindi nganda. Irangi rya Latex nigice cyingenzi mubikoresho bigezweho byo gushushanya inyubako, kandi kongerwamo HEC ntibishobora gusa kunoza irangi ryirangi rya latex, ahubwo binanoza imikorere yubwubatsi.
1. Ibiranga shingiro bya hydroxyethyl selile
Hydroxyethyl selulose ni polymer-eruble polymer iboneka muguhindura imiti ukoresheje selile naturel nkibikoresho fatizo. Ibyingenzi byingenzi birimo:
Kubyimba: HEC ifite ingaruka nziza yo kubyimba, ishobora kongera cyane ubwiza bwirangi rya latex kandi igatanga irangi rya latex nziza cyane ya thixotropy na rheologiya, bityo igakora igifuniko kimwe kandi cyuzuye mugihe cyo kubaka.
Kubika amazi: HEC irashobora kubuza neza amazi guhumeka vuba mumarangi, bityo bikongerera igihe cyo gufungura irangi rya latex no kunoza imiterere yumye no gukora firime ya firime.
Igihagararo: HEC ifite imiterere ihamye yimiti muburyo bwa latx, irashobora kurwanya ingaruka zimpinduka za pH, kandi ntigira ingaruka mbi kubindi bikoresho bigize irangi (nka pigment nuwuzuza).
Kuringaniza: Muguhindura ingano ya HEC, gutembera no kuringaniza amarangi ya latex birashobora kunozwa, kandi ibibazo nko kugabanuka no gushira ibimenyetso muri firime yamabara birashobora kwirindwa.
Kwihanganira umunyu: HEC ifite kwihanganira electrolytite, bityo irashobora gukomeza gukora neza mumikorere irimo umunyu cyangwa andi mashanyarazi.
2. Uburyo bwibikorwa bya hydroxyethyl selulose mumarangi ya latex
Nkibyimbye na stabilisateur, uburyo bwingenzi bwibikorwa bya hydroxyethyl selulose mu irangi rya latex birashobora gusesengurwa muburyo bukurikira:
(1) Ingaruka
HEC ishonga vuba mumazi igakora igisubizo gisobanutse neza. Mugukora hydrogene ihuza molekile zamazi, molekile ya HEC irakinguka kandi ikongerera ubwiza bwumuti. Muguhindura ingano ya HEC, ubwiza bwirangi rya latex burashobora kugenzurwa neza kugirango bigerweho neza. Ingaruka yibyibushye ya HEC nayo ifitanye isano nuburemere bwayo. Mubisanzwe, hejuru yuburemere bwa molekile, ningirakamaro cyane kubyibuha.
(2) Ingaruka ihamye
Hano hari umubare munini wa emulisiyo, pigment hamwe nuwuzuza irangi rya latex, kandi imikoranire hagati yibi bice irashobora kubaho, bikavamo gusenya cyangwa kugwa kw'irangi rya latex. Nka colloide ikingira, HEC irashobora gukora sisitemu ihamye mugice cyamazi kugirango ibuze pigment nuwuzuza gutura. Byongeye kandi, HEC ifite imbaraga zo guhangana n’imihindagurikire y’ubushyuhe n’ingufu zogosha, bityo irashobora kwemeza ko irangi rya latex rihagarara mugihe cyo kubika no kubaka.
(3) Kunoza kubaka
Porogaramu ikora irangi rya latex biterwa ahanini nimiterere ya rheologiya. Mu kubyimba no kunoza imvugo, HEC irashobora kunoza imikorere yo kurwanya-sag irangi rya latex, ikemerera gukwirakwira neza hejuru yubutumburuke kandi bigatuma bidashoboka gutemba. Muri icyo gihe, HEC irashobora kandi kongera igihe cyo gufungura amarangi ya latex, igaha abubatsi igihe kinini cyo guhindura no kugabanya ibimenyetso bya brush na marike.
3. Nigute ushobora kongeramo hydroxyethyl selulose kumarangi ya latex
Kugirango ukoreshe neza ingaruka za hydroxyethyl selulose, uburyo bwiza bwo kongeramo ni ngombwa. Muri rusange, gukoresha HEC mu irangi rya latex birimo intambwe zikurikira:
(1) Mbere yo guseswa
Kubera ko HEC ishonga gahoro gahoro mumazi kandi ikunda guhura, mubisanzwe birasabwa kubanza gushonga HEC mumazi kugirango ikore igisubizo kimwe mbere yo kuyikoresha. Mugihe cyo gushonga, HEC igomba kongerwaho buhoro kandi igahinduka ubudahwema kugirango ikumire. Kugenzura ubushyuhe bwamazi mugihe cyo gusesa nabyo ni ngombwa cyane. Mubisanzwe birasabwa gukora iseswa kubushyuhe bwa 20-30 ° C kugirango wirinde ubushyuhe bwamazi bukabije bugira ingaruka kumiterere ya molekile ya HEC.
(2) Ongeraho gahunda
Mubikorwa byo gukora amarangi ya latex, mubisanzwe HEC yongerwaho mugihe cyo guterura. Iyo utegura irangi rya latex, pigment hamwe nuwuzuza byabanje gukwirakwizwa mugice cyamazi kugirango bibe ibicucu, hanyuma igisubizo cya HEC colloidal kongerwamo mugihe cyo gutatanya kugirango harebwe ko gishobora gukwirakwizwa muri sisitemu. Igihe cyo kongeramo HEC nuburemere bwo gukurura bizagira ingaruka kubyimbye, bityo rero bigomba guhinduka ukurikije ibisabwa byihariye mubikorwa nyabyo.
(3) Kugenzura ibipimo
Ingano ya HEC igira ingaruka itaziguye kumikorere ya latex. Mubisanzwe, umubare wongeyeho HEC ni 0.1% -0.5% yumubare wuzuye wamabara ya latex. HEC ntoya cyane izatera ingaruka zo kubyimba zidafite agaciro kandi irangi rya latex ntirishobora gutemba cyane, mugihe HEC nyinshi izatera ububobere kuba hejuru, bikagira ingaruka kumikorere. Kubwibyo, mubikorwa bifatika, igipimo cya HEC gikeneye guhindurwa muburyo bukurikije formulaire hamwe nibisabwa byubaka amarangi ya latex.
4. Koresha ingero za hydroxyethyl selulose mumarangi ya latex
Mu musaruro nyirizina, HEC yakoreshejwe cyane muburyo butandukanye bwo gusiga amarangi, nka:
Urukuta rw'imbere rwa latx irangi: Ibibyibushye hamwe n'amazi agumana amazi ya HEC bituma ashobora kunoza cyane imiterere iringaniza na anti-sag ya firime irangi murukuta rwimbere rwa latx irangi, cyane cyane mubushyuhe bwo hejuru aho ishobora gukomeza gukora neza.
Urukuta rw'inyuma latex irangi: Ihungabana hamwe n'umunyu wa HEC ituma itezimbere ikirere hamwe no gusaza kurukuta rwinyuma rwa latx irangi kandi ikongerera igihe cya serivisi ya firime.
Irangi rya anti-mildew latex: HEC irashobora gukwirakwiza neza imiti igabanya ubukana mu irangi rya anti-mildew kandi ikanoza uburinganire bwayo muri firime irangi, bityo igahindura ingaruka zo kurwanya indwara.
Nka nyongera nziza ya latx, hydroxyethyl selulose irashobora kunoza cyane imikorere y irangi rya latex binyuze mubyimbye, kubika amazi, ningaruka zihamye. Mubikorwa bifatika, gusobanukirwa neza uburyo bwo kongeramo uburyo na dosiye ya HEC birashobora kunoza cyane kubaka no gukoresha ingaruka za latex.
