AmaziUmukozi ukwirakwiza MFyo gutwikira ntabwo igira ingaruka gusa kumucyo, ahubwo inagira ingaruka kumitungo iringaniye. Ubusanzwe umuyonga ugenwa nubushuhe bwikwirakwizwa ryikibiriti. Gukorera mu mucyo ni ikintu kiranga igifuniko. Iyo hejuru mu mucyo, biroroshye kubona urwego rwo hasi. Iyo imbaraga zitwikiriye, imbaraga zo hasi zo gutwikira. Kuberako ibice bya pigment bihagaze neza mugikorwa cyo gukwirakwiza amazi yatose, imitungo iringaniza iriyongera, ibyo bikaba bishobora guteza imbere amazi ya Newton kandi bigirira akamaro umutungo uringaniye.

GutoseUmukozi ukwirakwiza MFitezimbere mu mucyo muguhindura ingano yubunini bwikwirakwizwa rya pigment (byinshi kandi bigufi). Kuri dioxyde ya titanium, indangagaciro yo kwangirika hamwe nuduce twinshi dushobora kwerekana neza no kugabanya urumuri rwuburebure butandukanye. Ongeraho polymerUmukozi ukwirakwiza MFirashobora guteza imbere ubuso (kugabanya polymer, kugabanya ingano yingingo) no kurushaho kunoza ubwishingizi. Kubintu bibonerana, polymer ikwirakwiza irashobora kunoza ingano yikwirakwizwa kandi ikemerera urumuri rwinshi kunyuramo (kongera umucyo). Ingano yumucyo igaragarira kandi ikanyura hejuru igena ubwishingizi cyangwa gukorera mu mucyo. Ubwoko bw'irangi no gutatanya byose bigira icyo bihindura. Bitewe ningaruka zingingo zingana nubunini buke, gutwikira pigment bigira ingaruka nini kumucyo ugaragara. Kubwibyo, turashobora kunoza umucyo twongeramo inyongeramusaruro.

Kuringaniza nubushobozi bwo gutwikira gukwirakwira hejuru. Ubuso butwikiriye ubusanzwe buterwa nubushyuhe bwo hejuru kandi bibaho vuba. Ibimenyetso byohanagura kumyenda yo gushushanya nabyo biterwa no kuringaniza bidahagije. Imyitwarire myiza irashobora gusobanurwa nubukanishi bwa Newtonian. Ariko nyuma ya pigment yinjijwe muri sisitemu, irahinduka. Ni ukubera ko ibice byoroshye kwibasirwa na thixotropy na pseudoplastique bitewe nubusabane bwimiti nubusabane bwumubiri. Kubwibyo, turashobora kunoza imitungo iringaniza twongeyeho inyongeramusaruro.

Gukwirakwiza ibishishwa bitose bikwiranye no gutwikira, pigment, paste yamabara nibindi bikoresho byinganda. Nkibyongeweho bisanzwe, gukwirakwiza ibishishwa bigira uruhare runini mukuzamura umucyo nuburinganire. Ingano yo gukwirakwiza ibishishwa ni bike, ariko birakenewe mugikorwa cyo gutwikira. Gutandukanya ibishishwa bitose bigira ingaruka kumucyo no koroha, bityo rero ni ngombwa cyane kongeramo ibishishwa bitose.
