Hariho izindi nyungu zo gukoresha hydroxyethyl selulose muri coatings?

Gukoresha hydroxyethyl selulose (HEC) mubitambaro bifite ibyiza byinshi, bikubiyemo ibintu bifatika, tekinike yo gutunganya ningaruka zo gukoresha.

1. Ingaruka mbi

Hydroxyethyl selile ni umubyimba mwiza ushobora kongera cyane ubwiza bwimyenda. Ingaruka yacyo irashobora kugera kubisubizo byingenzi kurwego rwo hasi rwiyongera, bityo bigatezimbere imikorere yimyenda. Ubwiza bw'irangi buringaniye, bushobora kwirinda ibibazo nko kugabanuka no kugabanuka mugihe cyo gushushanya, kandi bikazamura uburinganire bwubwubatsi hamwe nuburinganire bwa firime.

2. Kunoza umutekano

HEC ifite ingaruka nziza zo gutuza. Irashobora guhagarika ikwirakwizwa rya pigment hamwe nuwuzuza binyuze mumubiri uhuza umubiri hamwe nubufatanye bwimiti, bikarinda gutuza no gusenya pigment nuwuzuza mugihe cyo kubika cyangwa gukoresha. Ibi ntabwo byongerera igihe cyo kurangi irangi ahubwo binatanga no gukwirakwiza pigment mugihe cyo kuyisaba.

3. Kunoza imvugo

Hydroxyethyl selulose igira ingaruka zikomeye kuri rheologiya ya coating, bigatuma igifuniko kigaragaza imiterere ya pseudoplastique (shear thinning). Ku gipimo gito cyogosha, irangi rigumana ubwiza bwinshi, bworoshye guhagarara no kubika; mugihe ku gipimo cyogosha cyane (nkigihe cyoza no gutera), ubwiza bwirangi buragabanuka, byoroshye gutemba no kubishyira mubikorwa. Iyi mitungo yogosha ituma igifuniko cyoroha kuyikoresha mugihe cyo kuyikoresha, kandi firime yo gutwikira iroroshye ndetse niyo.

4. Kunoza ubukana bwa sag

Iyo ushyizeho irangi hejuru yubutumburuke, HEC irashobora kunoza cyane irangi ryirinda sag. Ibi biterwa ningaruka zabyo hamwe nimiterere ya rheologiya ituma irangi ryihuta gukora imiterere isa na gel nyuma yo kuyikoresha, bikagabanya impengamiro yo gutembera, bityo bikarinda irangi kunanuka no kugabanuka.

5. Kongera imiterere yubushuhe

HEC igumana neza neza, bityo ikongerera igihe cyo kumisha irangi. Ibi ni ingenzi cyane cyane kubitambaro bisaba igihe kinini cyo gukora, nk'irangi ryibiti, irangi ryubukorikori, nibindi. Igihe kinini cyo kumisha gitanga umwubatsi umwanya munini wo gukora kandi akirinda ibimenyetso byo gushushanya hamwe ningorane zubwubatsi ziterwa no gukama cyane irangi.

6. Kunoza imikorere yo gukaraba

Kubera ko HEC itezimbere imiterere ya rheologiya ningaruka zo kubyimba irangi, irangi ryerekana kuringaniza neza iyo ryogejwe. Iyo woza, irangi rishobora gukwirakwira neza nta kimenyetso cya brush, kandi firime ya nyuma yo gutwikira iroroshye kandi yoroshye. Ibi ni ingenzi cyane cyane kubutaka bwiza bwo hejuru, nkibikoresho byo mu nzu, ibinyabiziga bitwikiriye, nibindi.

HEC ifite imiti ihamye kandi ihuje kandi irahuza na sisitemu zitandukanye zo gutwikira, nk'amazi ashingiye ku mazi, amarangi ya latx, amarangi ashingiye ku mavuta, n'ibindi. ibiyigize, kandi ntabwo bizatera byoroshye impinduka zimiti muri formula.

8. Kunoza imikorere yo gutwikira

HEC ntabwo itanga gusa umubyimba no gutuza muburyo bwo gutwikira, ahubwo inatezimbere imiterere yumubiri wa firime. Kurugero, irashobora kunoza uburyo bwo guhangana, scrub irwanya no guhinduka kwa firime. Ibi bituma igifuniko cya nyuma kiramba, gishobora kugumana ubwiza bwimikorere nuburyo bukora mubidukikije bitandukanye.

9. Kurengera ibidukikije

HEC ni ibinyabuzima bishobora kwangirika bifite ibidukikije byiza byo kurengera ibidukikije. Ugereranije nububyimbye bumwe na bumwe, bufite umutwaro muke wibidukikije kandi ntibisohora ibintu byangiza mugihe cyo gukoresha. Ibi bihuye n’ibisabwa cyane byo kurengera ibidukikije by’inganda zigezweho kandi binahuza n’ibikenerwa n’abaguzi ku bicuruzwa bibisi.

10. Biroroshye kubyitwaramo no gutatanya

HEC ishonga byoroshye kandi ikwirakwiza mumazi kandi ikora amazi amwe. Mubikorwa byo gutwikira ibicuruzwa, gusesa no gutatanya bituma inzira yumusaruro yoroshye kandi idakunze guhura nibibazo bya agglomeration cyangwa iseswa rituzuye, kugabanya ibibazo mubikorwa byumusaruro no kuzamura umusaruro.

Gukoresha hydroxyethyl selulose muri coatings bifite ibyiza byinshi. Ntabwo itezimbere gusa imiterere yumubiri nubwubatsi bwububiko, ahubwo inazamura umutekano no kurengera ibidukikije biranga igifuniko. Ifite uruhare runini mugutegura amarangi agezweho, itanga ibisubizo bifatika kugirango ugere ku ngaruka nziza zo gushushanya. Hamwe niterambere ryikoranabuhanga rya coating hamwe no gutandukanya ibyifuzo byisoko, ibyifuzo bya HEC mubitambaro bizaba binini.
