Gukoresha hydroxyethyl selulose (HEC) mumarangi ya latex

Hydroxyethyl Cellulose (HEC) ningirakamaro ya elegitoronike yamazi ya elegitoronike ya selile, ikoreshwa cyane mububiko bwububiko, cyane cyane amarangi ya latex. Nukubyimbye neza, kurinda colloid, guhagarika ibikorwa nubufasha bwo gukora firime, bitezimbere cyane imikorere y irangi rya latex, byongera imiterere yubwubatsi bwirangi ningaruka ziboneka kubicuruzwa byarangiye.

1. Imiterere yimiti nimiterere ya hydroxyethyl selulose
Hydroxyethyl selulose ni selile ikomoka mu kwinjiza hydroxyethyl muri molekile ya selile. Nibintu bivangwa n'amazi ya polymer. Imiterere yimiti igena amazi meza kandi meza. Iyo ushonga mumazi, irashobora gukora igisubizo kiboneka cyane hamwe no gufatana neza, gukora firime no kubyibuha. Iyi mitungo igira uruhare runini mugushushanya kwa latex.

Hydroxyethyl selulose mubisanzwe ni ifu yera cyangwa yoroheje yumuhondo cyangwa granules, bigashonga byoroshye mumazi akonje cyangwa ashyushye kugirango bibe igisubizo gihamye. Igisubizo cyacyo gifite umutekano muke kandi kirashobora kurwanya neza aside, alkali, redox na mikorobe yangirika. Byongeye kandi, kubera imiterere itari ionic ya hydroxyethyl selulose, ntabwo ikora imiti hamwe nibindi bikoresho mu irangi rya latex nka pigment, ibyuzuza cyangwa inyongeramusaruro, bityo ikaba ifite ubwuzuzanye bwagutse muburyo bwo gusiga irangi.

2. Uburyo bwibikorwa bya hydroxyethyl selulose mumarangi ya latex
Mu irangi rya latex, uruhare rwa hydroxyethyl selulose rugaragarira cyane mubyimbye, kubika amazi, kongera umutekano no kunoza imikorere:

Ingaruka yibyibushye: Hydroxyethyl selulose, nkibyimbye neza, irashobora kongera ububobere bwirangi rya latex kandi ikongera thixotropy yayo. Ibi ntibibuza gusa irangi kugabanuka mugihe cyo kubika no kubishyira mu bikorwa, ariko kandi bituma irangi rirushaho kuba ryizunguruka cyangwa ryogejwe. Ingaruka nziza yibyiza ifasha kugenzura rheologiya yamabara ya latex, itanga ibyiyumvo byiza mugihe uyisabye, kandi igateza imbere firime.

Kubika amazi: Hydroxyethyl selulose ifite amazi meza. Mugihe cyo kumisha irangi rya latex, irashobora kubuza amazi guhumuka vuba, bityo bikongerera igihe cyo gufungura igihe cyo gufungura irangi kandi bikubaka neza. Byongeye kandi, gufata neza amazi birashobora kandi kugabanya gucikamo firime ya firime nyuma yo gukama, bityo bikazamura ubwiza rusange bwa firime.

Igihagararo: Hydroxyethyl selulose, nka colloide ikingira, irashobora gukumira neza pigment hamwe nuwuzuza gutura mumarangi ya latex. Irashobora gukora sisitemu ihamye ikoresheje igisubizo cyayo kugirango igabanye neza buri kintu kandi igumane ububiko bwamabara. Muri icyo gihe, hydroxyethyl selulose irashobora kandi kunoza ituze rya emulsiyo kandi ikirinda gusibanganya no guteranya sisitemu ya latex mugihe cyo kubika.

Ubwubatsi: Mugihe cyubwubatsi, ingaruka zo kubyimba no gusiga amavuta ya hydroxyethyl selulose ituma irangi rya latex rifite uburyo bwiza bwo gutwikira no kuringaniza, bishobora kugabanya neza ibimenyetso bya brush no kunoza neza ya firime. Byongeye kandi, kubera ko hydroxyethyl selulose ishobora kunoza thixotropy y irangi, irangi rya latex ryoroshe gukora mugihe cyo gusiga irangi, rifite amazi meza atarinze gutonyanga, kandi rikwiranye nuburyo butandukanye bwubwubatsi, nko gukaraba, gutwikira umugozi no gutera .

3. Ingaruka zihariye zo gukoresha hydroxyethyl selulose mumarangi ya latex
Kunoza ububiko bwokubika amarangi: Ongeramo urugero rukwiye rwa hydroxyethyl selulose kumata ya latex irangi irashobora kuzamura cyane imiterere yo kurwanya gutuza irangi kandi ikirinda gushira pigment hamwe nuwuzuza. Ikwirakwizwa rya hydroxyethyl selulose mu mwenda rishobora gukomeza uburinganire bwa sisitemu yo gutwikira no kongera igihe cyo kubika ibicuruzwa.

Kunoza imiterere ya rheologiya yimyenda: Imiterere ya rheologiya yamabara ya latx ningirakamaro mubwubatsi. Hydroxyethyl selulose irashobora gukoresha thixotropy idasanzwe kugirango irangi ritemba byoroshye munsi yimbaraga zogosha (nko mugihe cyo gushushanya), kandi bikagumana ubukonje bwinshi munsi yimbaraga nke (nko guhagarara), bikarinda Sag. Ibiranga bituma irangi rya latex rigira ingaruka nziza zo kubaka no gutwikira, kugabanya kugabanuka no kuzunguruka.

Kunoza ingaruka zigaragara nibintu bifatika bya firime: Hydroxyethyl selulose igira uruhare runini mugikorwa cyo gukora film. Ntishobora gusa kunoza imikorere ya firime irangi gusa, ahubwo irashobora no kongera imbaraga zo kwambara no kurwanya amazi ya firime irangi, ikongerera igihe cyo gukora cya firime. Byongeye kandi, kubera gufata neza amazi, igishishwa cyumye neza, gifasha kwirinda ibibazo nkiminkanyari, pinholes no guturika, bigatuma ubuso bwikibiriti bworoha.

Kunoza imikorere y’ibidukikije: Hydroxyethyl selulose ni inkomoko ya selile isanzwe, ifite ibinyabuzima byiza cyane, kandi ntibizanduza ibidukikije. Ugereranije nubukorikori gakondo bwa syntetique, bwangiza ibidukikije kandi bwujuje ibisabwa mubikoresho byubaka bigezweho. Byongeye kandi, ntabwo irimo ibinyabuzima bihindagurika (VOC), bityo gukoresha hydroxyethyl selulose mu irangi rya latex bifasha kugabanya imyuka ihumanya ikirere no kuzamura ikirere cy’ibidukikije byubaka.

Nka nyongeramusaruro yingenzi mumarangi ya latex, hydroxyethyl selulose irashobora kunoza cyane imikorere yubwubatsi ningaruka zanyuma zo gusiga irangi rya latx binyuze mubyimbye byayo byiza, kubika amazi, gutuza no gukora firime. Muri icyo gihe, kubera kurengera ibidukikije no kuranga VOC nkeya, hydroxyethyl selulose yujuje ibyatsi n’ibidukikije by’inganda zigezweho. Hamwe niterambere ryiterambere ryikoranabuhanga, ibyifuzo bya hydroxyethyl selulose mumarangi ya latex bizaba binini, bitanga ibisubizo byiza byiterambere rirambye ryinganda zububiko.
