Icapiro rya pigment vs gucapa irangi

Gucapa

Ibyo bita gucapa ni uburyo bwo gutunganya amarangi cyangwa irangi mu ibara ryamabara, ukabishyira mubikorwa byimyenda no gucapa.Kugirango urangize icapiro ryimyenda, uburyo bwo gutunganya bwitwa inzira yo gucapa.

Icapiro rya pigment

Icapiro rya pigment nuburyo bwo gucapa aho pigment ishyirwa muburyo bwimyenda hifashishijwe umwenda mwinshi wa polymer (adhesive) hamwe nibintu byamabara adashobora gushonga (pigment) kugirango bibe firime yamabara akomeye, ibonerana kandi idashobora kwambara kumyenda.

Gucapa irangi

Kubijyanye nuburyo bwo gusiga irangi fibre, gucapa no gusiga irangi ni kimwe, usibye ko mugucapura, irangi ryamabara runaka rikoreshwa mugace k’imyenda ukurikije ibisabwa, kandi nyuma yo kuvurwa runaka, irangi irangi fibre, hanyuma ibicuruzwa byacapwe hamwe nibara rimwe cyangwa byinshi biboneka kumyenda.Kubwibyo, icapiro rishobora nanone kuvugwa ko ari "irangi ryaho".

Ihame ryamabara

Icapiro rya pigment nuburyo bwo gucapa buhagarika ibifatika gukora firime ihamye, ibonerana kandi idashobora kwambara kumyenda, kugirango ikosore irangi kumyenda.

Amabara y'ibara

Irangi ni uburyo bwo gutunganya aho ibikoresho byimyenda bibona amabara meza kandi akomeye binyuze mumubiri, imiti cyangwa imiti-nganda ihuza amarangi (cyangwa pigment) nibikoresho byimyenda.

Ibyiza n'ibibi

Icapiro rya pigment

Ibyiza:

•Gukoresha byoroshye, inzira yoroshye, umusaruro mwinshi wumurimo, birashobora kugabanya gusohora amazi mabi

•Chromatogramu yagutse, urumuri rwinshi, imirongo isobanutse neza hamwe na kontours

•Irakwiriye uburyo bwihariye bwo gucapa, kandi irashobora no gukoreshwa mugusohora no gucapa irangi

•Ibara ryoroshye rihuye nibara ryiza ryororoka

•Irakwiriye gucapura imyenda y'ibikoresho bitandukanye bya fibre, cyane cyane imyenda ivanze.

Ibibi:

• Ukuboko guke kumva, gukama kwumye kandi gutose

• Gukoresha kerosene muri paste emulisile ihumanya ikirere;Benshi muri ba monomers bakoreshwa mugutegura ibifata ni uburozi

• Ibara ryaka ntirimeze neza nkiryo ryandika irangi rifite imiterere ihwanye

• Ibifata byoroshye gukuramo no guhagarika mesh

Icapiro ry'irangi (gufata amarangi akora nk'urugero)

Ibyiza:

• Hariho ubwoko bwinshi, chromatogramu yuzuye n'amabara meza

• Nibyiza gutegura ibara ryamabara, uburyo bworoshye bwo gucapa, ingaruka nziza nudusembwa duke

• Kwihuta kwiza kuvura

• Igiciro gito cyo gucapa kandi guhuza amabara byoroshye

Ibibi:

• Benshi muribo ntibarwanya chlorine, kandi igipimo cyo gukosora ni gito.Amabara amwe amwe afite icyerekezo gikomeye (affinity), byoroshye gutera umwanda mugihe cyo gusabune, cyane cyane iyo ucapuye amabara yimbitse kandi yimbitse.

Itandukaniro:

Itandukaniro rinini hagati yo gucapa irangi no gucapa pigment nuko icapiro ryibara rihujwe nigitambara muguhuza umubiri, mugihe icapiro ryirangi rihuzwa neza nigitambara nimbaraga za van der Waals.

Icapiro rya pigment rirashobora gukoreshwa mugutunganya imyenda yose ya fibre.Ifite ibyiza byinshi mugucapisha imvange hamwe nigitambara.Ifite inzira yoroshye, chromatografi yagutse, ishusho yindabyo isobanutse, ariko ukuboko guke kumva no kwihuta gukabije.Kwihuta kwabo kwihuta no guhanagura byumye nibyiza, ndetse nibyiza, kuburyo bikoreshwa cyane mubitambaro byo gushushanya, ibitambara byumwenda hamwe nigitambara cyimyenda ikenera isuku yumye.

Nigute ushobora gutandukanya gucapa irangi no gucapa pigment

Icapiro rya pigment hamwe no gusiga irangi birashobora gutandukanywa mugereranya itandukaniro rikomeye hagati yigice cyacapwe nigice kitacapishijwe umwenda umwe.Ukuboko kwumva irangi ryacapwe rirakomeye gato ugereranije n'ahantu hatacapwe, hashobora kuba habyimbye gato.Niba umwenda wacapishijwe amarangi, nta tandukaniro rigaragara rigaragara hagati yigice cyacapwe nigice kitacapwe.
