Itsinda ry'ibintu bifite ibara
Itsinda ry’abahanga ni ubwoko bushya bw’irangi ryagenewe ibikoresho bya polymer, rizwi kandi nk’itegurwa ry’irangi. Rigizwe n’ibintu bitatu by’ibanze: amarangi cyangwa irangi, ibitwara n’inyongera. Ni ihuri riboneka binyuze mu gushyira amarangi menshi cyangwa irangi ku maresin kandi rishobora kwitwa ihuri rinini. Kubwibyo, imbaraga zaryo zo gusiga irangi ni nyinshi kuruta iz’amabara ubwayo. Mu magambo make: Itsinda ry’abahanga mu gusiga irangi ni ihuri riboneka binyuze mu gushyira amarangi menshi cyangwa irangi ku maresin.
01 Imiterere
Amabara cyangwa irangi
Amabara ashyirwa mu byiciro bitandukanye birimo amabara y’umwimerere n’ay’inorganic
Amabara y’umwimerere akunze gukoreshwa arimo: umutuku wa phthalocyanine, ubururu bwa phthalocyanine, icyatsi kibisi cya phthalocyanine, umutuku utukura w’urumuri, umuhondo wa macromolecular, umuhondo wa macromolecular, umuhondo uhoraho, umuhengeri uhoraho, umutuku wa azo, nibindi.
Amabara asanzwe akoreshwa arimo: umutuku wa cadmium, umuhondo wa cadmium, dioxyde ya titanium, umukara wa karuboni, umutuku wa oxyde y'icyuma, umuhondo wa oxyde y'icyuma, n'ibindi.
Umukozi
Igikoresho cyo gutwara ibintu ni cyo shingiro rya masterbatch y'amabara. Ibyuma byihariye byo gutwara ibintu bikunze guhitamo resin imwe n'igicuruzwa cya resin n'igikoresho cyo gutwara ibintu, kandi guhuza hagati yabyo byombi ni byo byiza kurusha ibindi. Ariko, uburyo gikoresho cyo gutwara ibintu nabyo bigomba gusuzumwa icyarimwe.
Imashini itatanya
Kugira ngo habeho gukwirakwira kw'amabara ku buryo bumwe no kuyarinda gushonga, aho gushonga kw'amabara bigomba kuba biri hasi ugereranyije n'aho ashongeshejwe, kandi bigomba kuba bihuye neza na resin kandi bikagira isano nziza n'amabara. Amabara akoreshwa cyane ni: ishashi ya polyethylene ifite uburemere buke na stearate.
Inyongeramusaruro
Nk'ubwoko bugabanya umuriro, butuma habaho urumuri, burwanya udukoko, burwanya udukoko tudakomeye, burwanya utunyangingo n'ubundi bwoko, keretse iyo umukiriya abisabye, muri rusange ntabwo burimo ibintu byavuzwe haruguru muri masterbatch y'amabara.
02 Ibyiza
a.Kugira ngo ibara rirusheho gukwirakwira mu gicuruzwa Mu gihe cyo gukora ibara ry’amabara, ibara rigomba gutozwa kugira ngo ryongere ubushobozi bwo gukwirakwira no gusiga irangi. Ibara ryihariye rikoreshwa mu gutwara ibara ry’amabara ni kimwe n’ubwoko bwa pulasitiki bw’igicuruzwa, rifite ubushobozi bwo guhuza neza. Nyuma yo gushyushya no gushonga, uduce tw’ibara dushobora gukwirakwira neza muri pulasitiki y’igicuruzwa.
b.Bifasha mu kubungabunga ubuziranenge bw'ibinyabutabire bw'ibara. Iyo ibara rikoreshejwe mu buryo butaziguye, rizafata amazi rigashira bitewe n'uko rihuye n'umwuka mu gihe cyo kubika no gukoresha. Ariko, nyuma yo kugirwa ibara ry'ingenzi, ibara ritwara resin ritandukanya ibara n'umwuka n'ubushuhe, ibyo bigatuma ibara rigumana ubuziranenge bw'ibara ridahinduka igihe kirekire.
c.Menya neza ko ibara ry'ibicuruzwa rihamye. Uduce twa Masterbatch dusa n'uduce twa resin, bigatuma tworoha kandi tugapima neza. Ntidufata ku gikoresho mu gihe cyo kuvanga kandi duhuza neza na resin. Bityo, ingano y'inyongera ishobora kwemezwa, bityo bigatuma ibara ry'ibicuruzwa rihamye.
D.Kurinda ubuzima bw'abakora. Muri rusange, ibara riba riri mu ishusho y'ifu kandi rikunda kuguruka iyo ryongewemo kandi rikavangwa. Iyo umubiri w'umuntu umaze guhumeka, rizagira ingaruka ku buzima bw'abakora.
na.Komeza ibidukikije bisukuye
f.Byoroshye gukoresha
Uruganda rwacu rukoresha amabara menshi y’amabara atandukanye mu gukora imiyoboro ya pulasitiki, ibyo bigatuma habaho imiterere itandukanye kandi bigatuma imiyoboro irushaho kuba myiza.
