Gucapa neza no gucapa amarangi nuburyo bubiri buzwi bwo gucapa mumyaka yashize.Ibikurikira bizibanda cyane kuri ubu buryo bubiri bwo gucapa.
Gucapura IGIKORWA
Mbere ya byose, icya mbere ni ugucapa neza, gusiga amarangi bitunganywa no gucapa no gusiga irangi.Ibishushanyo mbonera byo gucapa bikora biratandukanye: indabyo ziterwa, ibishushanyo bya geometrike, inyuguti zicyongereza hamwe nibice bitandukanye byamabara byahujwe muburyo bwo kwerekana uburyo butandukanye bwo gushushanya binyuze muburyo bwo gushushanya.Imyenda nkiyi ikwiranye nitsinda ryinshi kandi ryakoreshejwe igihe kirekire.Igitambaro cyacapwe gifite ibara ryiza, amabara meza yihuta, kumva amaboko yoroshye, birashobora gukaraba kenshi bitazimye, kandi bigakoreshwa nkibishya mugihe kirekire.
Kuberako icapiro ryoroshye ryumva ryoroshye kandi ntirishire byoroshye, ibicuruzwa byangiza uruhu nkaingofero, umusegonaibiringitiizakoresha tekinoroji yo gucapa
Gucapura KUBONA
Gukoresha imiterere ya thermo cyangwa thermoplastique syntetique resin nka binder, ivanze na pigment idashobora gushonga, igizwe na paste yo gucapa irangi, ushyirwa hejuru yigitambara hakoreshejwe uburyo bwa mashini cyangwa intoki, nyuma yo kumisha no guteka kugirango ube urwego rwa firime, kugirango pigment itwikiriwe cyane kuri fibre, kugirango ugere ku ntego yo gucapa no gusiga amabara.Ibicuruzwa bisohora irangi mubusanzwe bigizwe na pigment paste, binder, ifoto coagulant na emulsifier, bishobora kuvangwa iyo bikoreshejwe.
Gucapa irangi nuburyo buhendutse bwo gucapa muburyo bwo gucapa, kubera ko gucapa irangi byoroshye, bisaba inzira ntoya, kandi mubisanzwe ntibisaba amavuta no gukaraba.Impuzu ziza zifite amabara meza, akungahaye kandi arashobora gukoreshwa kumyenda yose.Bafite umuvuduko mwinshi wumucyo kandi byumye byumye, ndetse nibyiza cyane, kuburyo bikoreshwa cyane mubitambaro byo gushushanya, ibitambara byumwenda hamwe nigitambara cyimyenda ikenera isuku yumye.Mubyongeyeho, irangi ntirishobora gutanga amabara manini atandukanye kumyenda itandukanye, kandi inapfundikira ibara shingiro neza mugihe icapiro.
Hamwe no gukaraba cyangwa guhanagura byumye, icapiro ryirangi rizagenda rishira buhoro buhoro kandi amabara azagenda yoroha.
ITANDUKANIRO HAGATI YABIRI
1. Inzira iratandukanye
Gucapa irangi ni ugukoresha thermosetting cyangwa thermoplastique syntetique resin nka binder, ivanze na pigment idashobora gushonga, igizwe na paste yo gusiga irangi, ushyirwa hejuru yigitambara hakoreshejwe uburyo bwa mashini cyangwa intoki, nyuma yo kumisha no guteka kugirango ube urwego rwa firime, kugirango pigment itwikiriwe neza kuri fibre, kugirango ugere ku ntego yo gucapa amabara.
Gucapa neza, mugikorwa cyo gusiga no gucapa, itsinda rikora ryirangi ryirangi rikora guhuza hamwe na molekile ya fibre, kugirango irangi na fibre bibe byose.
2. Ibiranga biratandukanye
Gucapa neza no gusiga irangi ni ukongeramo azo na formaldehyde mugikorwa cyo gucapa no gusiga irangi, ntabwo irimo ibintu byangiza umubiri wumuntu, kandi ntibishira mugihe cyo gukaraba, ibara nigitambara byumva neza, kandi ntihazabaho ibyiyumvo bikomeye kandi byoroshye. .
Gucapa irangi, icapiro ryacapwe, ibara ryerurutse kandi ryiza, urumuri rwiza.Irashobora guha umwenda ibyuzuye, byumye kandi byoroshye, cyane cyane byihuta cyane byo kwihuta, gukoresha neza umuvuduko wumye kandi utose birashobora kugera kuri ≥4 (reba gusa), kwihuta gukaraba neza, guhumeka neza kwumwuka.
