Lithopone, izwi kandi ku izina rya zinc sulfide na barium sulfate, ni pigment yera ikoreshwa cyane mu nganda zitandukanye, kimwe mu bikorwa byayo nyamukuru ni ugukora amarangi ya latex. Iyo uhujwe nadioxyde de titanium, lithopone ihinduka ikintu cyingenzi mugukora ibicuruzwa byiza. Muri iyi blog tuzareba imikoreshereze ya lithopone mu marangi ya emulsion hamwe nibyiza byayo kurenza izindi pigment.
Kimwe mubanzeikoreshwa ryalithoponemuri latex irangi nubushobozi bwayo bwo gutanga ubwiza buhebuje. Iyo uhujwe na dioxyde ya titanium, lithopone ikora nka pigment yagutse, ifasha kuzamura umweru muri rusange no kumurika irangi. Ibi bitanga byinshi ndetse kandi bigahoraho, bigatuma biba byiza haba imbere ndetse no hanze.
Usibye gukwirakwizwa no kutagaragara, lithopone ifite kandi ibihe byiza byo guhangana nikirere kandi biramba. Iyo ikoreshejwe irangi rya latex, lithopone ifasha kurinda hejuru yinyuma kwangirika kwizuba ryizuba, ubushuhe, nibindi bintu bidukikije. Ibi bituma ihitamo hejuru kubikorwa byo gusiga irangi hanze kuko bifasha kugumana ubunyangamugayo nibara ryirangi mugihe.
Byongeye kandi, ukoresheje lithopone muriamarangiirashobora gutanga inyungu zibiciro kubabikora. Bitewe nigiciro cyacyo gito ugereranije nibindi byera byera nka titanium dioxyde, lithopone ifasha kugabanya igiciro rusange cyibikorwa byamabara. Iyi nyungu ihendutse ituma abayikora bakora ibicuruzwa byujuje ubuziranenge ku giciro gito, gishobora noneho guhabwa abaguzi ba nyuma.
Iyindi nyungu ikomeye yo gukoresha lithopone mumarangi ya latex ni uguhuza nibindi byongeweho kandi byuzuza. Lithopone irashobora kuvangwa byoroshye ninyongeramusaruro zinyuranye niyongera, bigatuma abayikora bahuza imikorere yimyenda kugirango bahuze ibyifuzo byabakiriya. Ihinduka ryimikorere ituma lithopone ihinduka kandi ihindagurika kubakora ibicuruzwa.
Nubwo lithopone ifite inyungu nyinshi, birakwiye ko tumenya ko hashobora no kubaho imbogamizi zo gukoresha lithopone mu irangi rya latex. Kurugero, lithopone ntishobora gutanga urwego rumwe rwera nimbaraga zo guhisha ugereranije na dioxyde de titanium. Kubwibyo, ababikora bagomba kuringaniza neza imikoreshereze yibi pigment bashingiye kumiterere bifuza.
Mu gusoza,lithoponeni pigment ifite agaciro kandi itandukanye yakoreshejwe cyane mugukora amarangi ya emulsion. Ihuza ryihariye ryikwirakwizwa, kurwanya ikirere, gukora neza no guhuza bituma bihitamo bwa mbere kubakora ibicuruzwa bifuza gukora ibicuruzwa byujuje ubuziranenge kubikorwa bitandukanye. Iyo uhujwe na dioxyde ya titanium nibindi byongeweho, lithopone ifasha gukora ibifuniko biramba, birebire kandi bikurura amashusho byujuje ibyifuzo byabaguzi nibidukikije.
