Hydroxyethyl Cellulose (HEC) ni ikintu gikunze kuboneka mu gusiga amarangi. Nibyimbye bifasha kunoza ubwiza nuburinganire bwirangi. Muri iki kiganiro, tuzaganira ku buryo bwo gukora amarangi ashingiye ku mazi hamwe na HEC.

1. Ibikoresho Uzakenera gukora irangi rishingiye kumazi hamwe na HEC ni:

• Ifu ya HEC
• Amazi
• Ibara
• Kurinda ibintu (bidashoboka)
• Ibindi byongeweho (bidashoboka)

2. Kuvanga ifu ya HEC Intambwe yambere nukuvanga ifu ya HEC namazi. Ubusanzwe HEC igurishwa muburyo bwifu, kandi igomba kuvangwa namazi mbere yuko ikoreshwa mumarangi. Ingano yifu ya HEC uzakenera gukoresha biterwa nubunini bwifuzwa hamwe nubwiza bwirangi ryawe. Amategeko rusange ni ugukoresha 0.1-0.5% ya HEC ukurikije uburemere bwirangi.

Kuvanga ifu ya HEC n'amazi, kurikiza izi ntambwe:

• Gupima ingano yifu ya HEC hanyuma uyongere kuri kontineri.
• Buhoro buhoro shyiramo amazi muri kontineri mugihe ukurura imvange ubudahwema. Ni ngombwa kongeramo amazi gahoro gahoro kugirango wirinde ifu ya HEC.
• Komeza kubyutsa kugeza ifu ya HEC imaze gushonga mumazi. Iyi nzira irashobora gufata ahantu hose kuva muminota 10 kugeza kumasaha, bitewe nubunini bwa HEC ukoresha.

3. Ongeramo Pigment Iyo umaze kuvanga ifu ya HEC namazi, igihe kirageze cyo kongeramo pigment. Ibara ni amabara atanga irangi ibara ryayo. Urashobora gukoresha ubwoko ubwo aribwo bwose bwa pigment ushaka, ariko ni ngombwa gukoresha pigment yo mu rwego rwohejuru ihuje n'amabara ashingiye kumazi.

Kugirango wongere pigment ivanze rya HEC, kurikiza izi ntambwe:

• Gupima urugero rwifuzwa rwa pigment hanyuma wongere kuri HEC ivanze.
• Koresha imvange ubudahwema kugeza pigment ikwirakwijwe rwose muruvange rwa HEC. Iyi nzira irashobora gufata iminota mike.

4. Guhindura Viscosity Muri iki gihe, ugomba kugira irangi ryinshi rivanze. Ariko rero, urashobora gukenera guhindura ububobere bwirangi kugirango urusheho gutemba cyangwa kubyimbye, bitewe nuburyo wifuza. Urashobora kubikora wongeyeho amazi menshi cyangwa ifu ya HEC.

Kugirango uhindure ubwiza bwirangi ryawe, kurikiza izi ntambwe:

• Niba irangi ari ryinshi, ongeramo amazi make muruvange hanyuma ubyinjizemo. Komeza wongere amazi kugeza ugeze mubwiza bwifuzwa.
• Niba irangi ari rito cyane, ongeramo agace gato ka poro ya HEC muruvange hanyuma ubyinjizemo. Komeza wongereho ifu ya HEC kugeza ugeze mubwiza bwifuzwa.

5. Ongeramo ibintu bibika hamwe nibindi byongeweho Hanyuma, urashobora kongeramo ibintu byongeweho nibindi byongewe kumarangi yawe, niba ubishaka. Kurinda ibintu bifasha kurinda imikurire ya bagiteri na bagiteri mu irangi, mugihe izindi nyongeramusaruro zishobora kunoza imiterere y irangi, nko gufatira, kurabagirana, cyangwa igihe cyo kumisha.

Kugirango wongere ibintu birinda nibindi byongerera irangi, kurikiza izi ntambwe:

• Gupima urugero wifuzaga rwo kubungabunga cyangwa kongeramo hanyuma ukongereho kuvanga irangi.
• Koresha imvange ubudahwema kugeza igihe ibizigama cyangwa inyongeramusaruro bikwirakwijwe mu irangi. Iyi nzira irashobora gufata iminota mike.

6. Kubika Irangi ryawe Iyo umaze gukora irangi, urashobora kubibika muri kontineri ifite umupfundikizo ufatanye. Ni ngombwa kubika irangi ryawe ahantu hakonje, humye kandi ntiririnde izuba. Irangi rishingiye kumazi hamwe na HEC mubusanzwe rifite ubuzima bwamezi hafi 6 kugeza kumwaka, bitewe nuburyo bwihariye hamwe nububiko.

Mu gusoza, gukora amarangi ashingiye kumazi hamwe na Hydroxyethyl Cellulose ninzira yoroshye isaba ibintu bike byingenzi nubumenyi bwibanze bwo kuvanga tekinike. Ukurikije intambwe zavuzwe haruguru, urashobora gukora irangi ryiza-ryiza, riramba rikwiranye nuburyo butandukanye bwo gusaba, kuva kurukuta rwimbere kugeza mubikoresho nibindi byinshi.
