Irangi rya solvent ni ikintu cy'ingenzi mu nganda kuva kuri plastiki no gusiga amarangi kugeza ku mbaho z'ibiti hamwe na wino yo gucapa. Ibara ryinshi rifite amabara menshi yimiterere nibisabwa, bigatuma biba ingenzi mubikorwa.
Irangi rya solvent rishobora gushyirwa mubwoko butandukanye, harimo irangi ryicyuma, irangi ryamavuta, irangi rya nitrocellulose, irangi rya polyester, nibindi byinshi. Buri bwoko bufite imiterere yihariye hamwe nibisabwa. Bumwe mu buryo bukoreshwa cyane bwo gusiga amarangi ni muri plastiki no gukora inganda. Aya marangi arashobora gushonga mumashanyarazi kugirango akore ibisubizo byamabara. Uyu mutungo utuma biba byiza muburyo bwo gusiga amabara ya plastike. Yaba amabara meza yibikinisho bya pulasitike cyangwa sheen yubuso bwamabara, amarangi yumuti agira uruhare runini mukuzamura amashusho yibicuruzwa.
Gukoresha amarangi ya solvent ntabwo bigarukira gusa kuri plastiki no gusiga amarangi; zikoreshwa kandi cyane mu gusiga ibiti. Abakora ibiti bakunze gukoresha amarangi yumuti kugirango bongere amabara mubintu bitandukanye bikozwe mubiti, nk'ibikoresho n'imitako. Irangi rya solvent ryinjira cyane mumibabi yimbaho, ryemeza ndetse nigihe kirekire. Byongeye kandi, ibintu byumye-byumye bituma biba byiza muburyo bwo gutunganya ibiti neza.
Ubundi buryo bukoreshwa muburyo bwo gusiga amarangi ni mubikorwa byo gucapa wino. Irangi risanzwe rikoreshwa mugukora wino nziza kandi nziza-yo murwego rwo gucapa. Ihinduka ryirangi ryirangi ryorohereza kuvanga numuti uhuza, bikavamo gutatana neza kandi byumye-byumye byandika. Ibi bifasha uburyo bwo gucapa neza kandi neza mubikorwa bitandukanye nko gupakira, gusohora imyenda.
Reka noneho ducukumbure mubiranga amarangi ya solvent agaragara. Ikintu kigaragara ni ubwiza bwihuse bwurumuri, rwemeza ko amabara akomeza kuba imbaraga kandi ntagabanuka nubwo yaba ahuye nizuba cyangwa ubundi buryo bwimirasire ya UV. Uyu mutungo ni ingenzi kubisabwa bisaba kugumana amabara maremare, nkibicuruzwa bya pulasitiki byo hanze cyangwa ibishushanyo bisize irangi.
Irangi rya solvent rifite kandi imiti myinshi irwanya imiti, bigatuma ikenerwa ninganda zikunze guhura n’imiti ikaze, nk'imodoka cyangwa inganda. Zigumana uburinganire bwamabara nubwo zihura na solvets, amavuta cyangwa acide, byemeza kuramba, kuramba.
Byongeye kandi, amarangi ya solvent yerekana neza ubushyuhe bwumuriro, bigatuma akoreshwa mubisabwa birimo ubushyuhe bwinshi. Iyi mikorere ni ingirakamaro cyane muburyo bwo kubumba plastike cyangwa mugihe ushushanya ibintu bishobora guhura nubushyuhe.
Mu gusoza, amarangi ya solvent ni amabara atandukanye akoreshwa cyane mubikorwa bitandukanye. Imikoreshereze yabo mu nganda za plastiki no gusiga amarangi zirashobora kuvamo ibicuruzwa byiza kandi bigaragara neza. Abakora ibiti bungukirwa nubushobozi bwabo bwo kwinjira mumibabi yimbaho, bikavamo ikizinga kirekire. Inganda zo gucapa wino zishingiye kumashanyarazi yihuta kandi ikwirakwijwe neza kumarangi yamabara kugirango ikore wino nziza yo gucapa. Ibiranga amarangi yumuti, harimo kwihuta kwumucyo, kurwanya imiti, hamwe nubushyuhe bwumuriro, bigira uruhare mugukoresha kwinshi no kuramba. Haba kongeramo ibara mubikinisho bya pulasitike, gusiga ibiti, cyangwa gucapa ibishushanyo mbonera, amarangi ya solvent agira uruhare runini mukuzamura ubwiza nibikorwa byibicuruzwa byinshi.
