Iyo utegura irangi, ubwiza bwa HPMC (Hydroxypropyl Methylcellulose) bugira uruhare runini mugushikira icyifuzo, gukwirakwira, no gukora muri rusange.Iyi ngingo igamije gutanga uburyo bwa siyansi kugirango hamenyekane neza uburyo bwiza bwa HPMC bwo gushushanya amarangi, urebye ibintu nkubwoko bwa pigment, uburyo bwo gukoresha, nibiranga irangi wifuza.
Sobanukirwa n'uruhare rwa HPMC mugushushanya amarangi:
HPMC ikora nk'inyongeramusaruro nyinshi muburyo bwo gusiga amarangi, igira uruhare mukugenzura ibicucu, kubika amazi, hamwe no gukora firime.Ubukonje bwacyo bugira uruhare rutaziguye no gutondekanya irangi, kimwe nubushobozi bwo kwizirika ku bice bitandukanye.
Reba Ubwoko bwa Pigment hamwe no Kwibanda:
Ibara ritandukanye risaba urwego rutandukanye rwa HPMC kugira ngo rugere ku buryo bwiza kandi butajegajega mu gusiga irangi.Muri rusange, pigment yibanda cyane cyangwa iremereye, nka dioxyde de titanium cyangwa okiside ya fer, irashobora gusaba HPMC yo mu rwego rwo hejuru kugira ngo ihagarike kandi ikumire.Ibara ryoroshye, nk'irangi ryamabara cyangwa ibara ryibonerana, birashobora gusaba ubukonje buke HPMC kugirango ikwirakwize neza bitabangamiye umucyo.
Menya uburyo bwo gusaba hamwe n'ibiranga irangi:
Uburyo bwo gusaba hamwe nibiranga irangi byifuzwa nabyo bigira ingaruka nziza kuri HPMC.Urugero:
a.Brush / Roller Porogaramu: Ubushuhe buhebuje HPMC ikundwa cyane kugirango ushireho brush cyangwa roller kugirango igenzure neza amarangi, kugabanuka gusakara, hamwe no kugumana brush / roller.
b.Gusaba Gusaba: Ubukonje bwo hasi HPMC isanzwe ikoreshwa mugukoresha spray kugirango byorohereze atomisation ndetse bigere no kubikwirakwiza.
c.Kurwanya Sag: Kunoza ubukana bwa sag no kwirinda irangi gutonyanga cyangwa kugabanuka hejuru yubutumburuke, ubukonje bwinshi HPMC burashobora gukenerwa.
Kora ibizamini bya Rheologiya:
Kugirango umenye ubumenyi bwa HPMC bwiza bwo gukora amarangi, ibizamini bya rheologiya birashobora gukorwa.Ibi bizamini bipima imyitwarire noguhindura irangi mubihe bigenzurwa.Ibisubizo birashobora kuyobora guhitamo ubwiza bwa HPMC urebye ibintu nkigipimo cyogosha, impagarara zogosha, hamwe numwirondoro wijimye.
Ikizamini no Guhindura:
Ukurikije ibisubizo byikizamini cya rheologiya, urutonde rwinshi rwa HPMC rushobora kumenyekana nkabakandida bashobora gukora amarangi.Kora ibizamini bito ukoresheje uburyo bwo gusiga amarangi hamwe nubwiza butandukanye bwa HPMC murwego rwagaragaye.Suzuma ibyingenzi nkibikoresho byo gusaba, kuringaniza, kwihanganira sag, hamwe no gukama.Hindura ubwiza bwa HPMC nkuko bikenewe kugirango ugere kumikorere wifuza.
Kumenya neza uburyo bwiza bwa HPMC bwo gushushanya amarangi bisaba uburyo bwa siyansi busuzuma ibintu nkubwoko bwa pigment, uburyo bwo gukoresha, hamwe nibiranga irangi.Mugusobanukirwa uruhare rwa HPMC, gukora ibizamini bya rheologiya, no kugerageza no guhindura ingero zifatika, abakora amarangi barashobora kugera kubwiza bwiza kugirango bongere amarangi, kuringaniza, gufatana, hamwe nibikorwa muri rusange.Nibyingenzi kuringaniza neza kugirango ugere kubiranga irangi wifuza mugihe ukomeza ibisabwa bifatika muburyo bwo gusaba.
