Methyl Hydroxyethyl Cellulose (MHEC) ni selile itari ionic selile ikomoka kuri selile naturel. Yitabiriwe cyane mubikorwa bitandukanye byinganda kubera kubyimba bidasanzwe, kubika amazi, hamwe nibikorwa bya firime. Bumwe mu buryo bugaragara bukoreshwa na MHEC ni mu nganda zo gusiga amarangi no gutwikira, aho bigira uruhare runini mu kuzamura ibicuruzwa bihoraho, gukora, n'imikorere. Iyi nyandiko irasobanura imikoreshereze n’imikoreshereze ya MHEC mu kunoza imiterere y’irangi hamwe n’ibishushanyo, bisobanura ingaruka zabyo ku bintu bitandukanye nko kwiyegeranya, gutuza, gushyira mu bikorwa, ndetse n’ubuziranenge muri rusange.
1. Kugenzura Imiterere
1.1
MHEC ihabwa agaciro cyane kubushobozi bwayo bwo guhindura ububobere bwamabara. Viscosity nikintu gikomeye muburyo bwo gusiga amarangi no gutwikira kuko bigira ingaruka kumikorere, harimo gutemba, kuringaniza, no kurwanya sag. Muguhindura ibishishwa, MHEC iremeza ko irangi rigumana umubyimba wifuzwa, ryoroshya gukoreshwa no kugabanya gutemba mugihe cyo gukaraba cyangwa kuzunguruka.
1.2 Imyitwarire idahwitse
MHEC itanga imyitwarire ya pseudoplastique (shear-thinning) imyitwarire. Ibi bivuze ko irangi ryijimye rigabanuka mukibazo cyogosha (urugero, mugihe cyo koza cyangwa gutera) hanyuma ugakira mugihe imihangayiko ikuweho. Uyu mutungo wongera ubworoherane bwo gusaba kandi utanga igenzura ryiza kubyerekeranye na firime yerekana irangi, bigira uruhare muburyo bumwe no kurangiza umwuga.
2. Kongera imbaraga
2.1 Kunoza ihagarikwa
Imwe mu mbogamizi muburyo bwo gusiga irangi ni uguhagarika pigment no kuzuza. MHEC ifasha muguhagarika ibyo bice, gukumira ubutayu no kwemeza imvange imwe. Uku gushikama ningirakamaro mugukomeza ibara nuburyo butandukanye mugihe cyo gusaba no kubika.
2.2 Kwirinda Gutandukanya Icyiciro
MHEC nayo igira uruhare runini mukurinda gutandukana kwicyiciro mumabara ya emulsion. Muguhindura emuliyoni, iremeza ko icyiciro cyamazi namavuta gikomeza kuvangwa kimwe, kikaba ari ngombwa kugirango birambe kandi bihamye bya firime.
3. Ibyiza byo gusaba
3.1
Kwinjiza MHEC muburyo bwo gusiga irangi bitezimbere imikorere, bigatuma irangi ryoroha kuyikoresha. Itezimbere gukurura brush, kunyerera, hamwe na sprayability, nibyingenzi kubarangi babigize umwuga hamwe nabakunzi ba DIY kimwe. Iyi miterere yemeza ko irangi ryakwirakwijwe neza, ryiziritse neza hejuru, kandi ryumye kugeza rirangiye, ridafite inenge.
3.2 Igihe cyiza cyo gufungura
MHEC itanga amarangi hamwe nigihe kinini cyo gufungura, itanga igihe kirekire cyo gukoreshwa no gukosora mbere yuko irangi ritangira gushiraho. Ibi ni ingirakamaro cyane kubutaka bunini hamwe nakazi karambuye, aho kuvanga hamwe no gukoraho birakenewe kugirango tugere ku rwego rwo hejuru.
4. Gukora firime no kuramba
4.1 Ubunini bwa firime imwe
MHEC igira uruhare mu gushiraho firime imwe yo gusiga irangi, ikaba ari ingenzi kubikorwa byuburanga ndetse no kurinda. Ubunini bwa firime butajegajega ndetse no gukwirakwiza amabara kandi bikongera imico yo kurinda igifuniko, nko kurwanya ubushuhe, urumuri rwa UV, no kwambara imashini.
4.2 Kurwanya Kurwanya
Irangi ryakozwe na MHEC ryerekana ubuhanga bworoshye kandi bworoshye, bifasha mukurinda ko habaho ibice muri firime. Ibi ni ingenzi cyane mubidukikije bitewe nihindagurika ryubushyuhe hamwe nubutaka bwimikorere, byemeza igihe kirekire kandi cyiza cyubwiza bwimyenda.
5. Kubika Amazi
5.1 Amazi meza
Ubushobozi bwo hejuru bwo gufata amazi ya MHEC ni ingirakamaro haba mu mazi ashingiye ku mazi. Iremeza ko irangi rigumana ubushuhe mugihe kirekire, rifasha mumazi amwe ya pigment hamwe nuwuzuza. Uyu mutungo ningirakamaro kugirango ugere ibara hamwe nuburyo buhoraho muri firime yanyuma.
5.2 Kwirinda Kuma vuba
Mugutinda inzira yo kumisha, MHEC irinda ibibazo nkuruhu rutaragera no gukora firime mbi. Ukumisha kugenzurwa ningirakamaro kugirango ugere ku buso butagira inenge kandi butagira inenge no kugabanya ibyago byo kudatungana nka pinholes, ibice, hamwe no kubyimba.
6. Ibitekerezo by’ibidukikije n’umutekano
6.1 Ntabwo ari uburozi na biodegradable
MHEC ntabwo ari uburozi kandi ibora ibinyabuzima, bituma iba inyongeramusaruro yangiza ibidukikije mugusiga amarangi. Imikoreshereze yacyo ijyanye no kwiyongera kw'ibicuruzwa birambye kandi bitangiza ibidukikije mu bwubatsi no gutwikira.
6.2 Kugabanya ibinyabuzima bihindagurika (VOC)
Kwinjiza MHEC mumarangi ashingiye kumazi bifasha mukugabanya ibikubiye muri VOC, byangiza ubuzima bwabantu ndetse nibidukikije. Ibi bigira uruhare mu gukora amarangi make-VOC cyangwa zeru-VOC, bikaba bifite umutekano mukoresha mu nzu kandi byubahiriza amategeko akomeye y’ibidukikije.
7. Ubushakashatsi bwibibazo hamwe nuburyo bukoreshwa
7.1 Amabara yubatswe
Mu gusiga amarangi, MHEC itezimbere imikoreshereze yimikorere, itanga kurangiza neza kandi imwe kurukuta no hejuru. Itanga ubwishingizi buhebuje kandi budasobanutse, ningirakamaro kugirango ugere ku ngaruka nziza zifuzwa hamwe namakoti make.
7.2 Inganda
Ku nganda zikora inganda, aho kuramba no gukora aribyo byingenzi, MHEC itezimbere imiterere yubukanishi no kurwanya ibidukikije. Ibi bivamo impuzu zidashobora kwihanganira gukuramo, imiti, hamwe nikirere, bityo bikongerera igihe cyo kubaho hejuru yubuso.
7.3
Mumyenda idasanzwe, nkibikoreshwa mubiti, ibyuma, na plastiki, MHEC ifasha mukugera kumikorere yihariye. Kurugero, mubiti bitwikiriye ibiti, byongera kwinjira no gufatana, mugihe mubyuma, bitanga kurwanya ruswa kandi bikarangira neza.
Methyl Hydroxyethyl Cellulose (MHEC) ninyongeramusaruro itandukanye iteza imbere cyane imikorere no gusiga amarangi. Ingaruka zayo mukugenzura ibicucu, kongera umutekano, imitungo ikoreshwa, gushiraho firime, gufata amazi, hamwe n’umutekano w’ibidukikije bituma iba ikintu cyingirakamaro mu gutunganya amarangi agezweho. Mugihe icyifuzo cyo gusiga irangi ryiza, rirambye, kandi ryorohereza abakoresha amarangi rikomeje kwiyongera, uruhare rwa MHEC mukuzuza ibyo bisabwa rugenda ruba ingenzi. Ubushobozi bwayo bwo kuzamura ubuziranenge muri rusange no kuramba byimyenda yemeza ko bizakomeza kuba ingenzi mubikorwa byo gusiga amarangi no gutwika imyaka iri imbere.
