Hydroxyethyl Cellulose (HEC) nikintu gisanzwe gikonjesha amazi ya polymer ikoreshwa cyane mumarangi ya latex. Ntabwo igira uruhare runini mugutezimbere ibicuruzwa, ahubwo inatezimbere cyane uburambe bwo gusaba hamwe nubwiza bwa firime yanyuma.
Ibyiza bya Hydroxyethyl Cellulose
Hydroxyethyl selulose ni ether ya selulose ether ikomoka muri selile naturel binyuze muri etherification. Ifite umubyimba mwiza, guhagarika, gutatanya no kwigana ibintu. Iyi mitungo ituma HEC ikora colloide ihamye mubisubizo byamazi hamwe nubwiza bwinshi hamwe nibyiza bya rheologiya. Byongeye kandi, igisubizo cyamazi ya HEC gifite umucyo mwiza nubushobozi bwo gufata neza amazi. Ibiranga bituma ikoreshwa cyane mumarangi ya latex.
Uruhare mu irangi rya latex
umubyimba
Nka kimwe mubyingenzi byingenzi byerekana irangi rya latex, umurimo wingenzi wa HEC nukwongera ububobere bwamazi yo gusiga irangi. Ubukonje bukwiye ntibushobora gusa kunoza ububiko bwamabara ya latex, ariko kandi birinda imvura kugwa. Byongeye kandi, ibishishwa bikwiye bifasha kugenzura kugabanuka no kwemeza kuringaniza no gukwirakwiza mugihe cyo gusaba, bityo ukabona firime imwe.
iterambere rihamye
HEC irashobora kunoza cyane ituze ryamabara ya latex. Mu gusiga irangi rya latex, HEC irashobora gukumira neza pigment hamwe nuwuzuza gutuza, bigatuma irangi riguma ritatanye mugihe cyo kubika no gukoresha. Uyu mutungo ni ingenzi cyane kububiko bwigihe kirekire, bifasha kongera igihe cyo kuramba cya latex.
Kubika amazi
Kubaka amarangi ya latx mubisanzwe bikubiyemo gukoresha amazi menshi, kandi uburyo bwiza bwo gufata amazi bwa HEC butuma firime ya coating itose neza mugihe cyo kumisha, birinda inenge zubutaka nko guturika, ifu nibindi bibazo biterwa no guhumeka vuba kwamazi . Ibi ntabwo bifasha gusa gukora firime yo gutwikira, ahubwo binanoza gukomera no kuramba kwa firime.
Guhindura imiterere
Nkumuhinduzi wa rheologiya, HEC irashobora guhindura imyitwarire yo kunanura imisatsi ya latx, ni ukuvuga ko ububobere bwirangi bwagabanutse ku gipimo cyinshi (nko gukaraba, gutwikira umugozi, cyangwa gutera), byoroshye kubishyira mu bikorwa, no kuri igipimo gito. Gusubirana kwijimye ku gipimo cyogosha (urugero nko kuruhuka) birinda kugabanuka no gutemba. Iyi mitungo ya rheologiya igira ingaruka itaziguye kubwubatsi nubwiza bwa nyuma bwo gusiga irangi rya latex.
Gutezimbere ubwubatsi
Itangizwa rya HEC rirashobora kunoza cyane imikorere yamabara ya latex, bigatuma irangi ryoroha kandi rikaba rimwe mugihe cyo gusaba. Irashobora kugabanya ibimenyetso bya brush, gutanga ubworoherane nuburabyo bwa firime ya coating, no kunoza uburambe bwabakoresha.
Hitamo kandi ukoreshe
Muri latex irangi ryerekana, guhitamo hamwe na dosiye ya HEC bigomba guhinduka ukurikije ibikenewe byihariye. HEC ifite viscosities zitandukanye hamwe na dogere zo gusimbuza bizagira ingaruka zitandukanye kumikorere ya latex. Muri rusange, HEC ikwiranye cyane na HEC irakwiriye cyane kubirangi byirabura bisize irangi bisaba ubukonje bwinshi, mugihe HEC ifite ubukonje buke ikwiriye gusiga irangi ryoroshye kandi rifite amazi meza. Byongeye kandi, umubare wa HEC wongeyeho ugomba gutezimbere ukurikije ibikenewe nyabyo. HEC cyane izatera umubyibuho ukabije wa coating, itajyanye nubwubatsi.
Nibyingenzi byingenzi byongeweho, hydroxyethyl selulose igira uruhare runini mugushushanya irangi: kubyimba, gutuza, kugumana amazi no kunoza imikorere. Gukoresha mu buryo bushyize mu gaciro HEC ntibishobora gusa kunoza ububiko bwimikorere nubwubatsi bwamabara ya latex, ariko kandi bizamura cyane ubwiza nigihe kirekire cya firime. Hamwe niterambere ryinganda zitwikiriye hamwe niterambere ryikoranabuhanga, ibyifuzo bya HEC mumarangi ya latex bizaba binini.
