Ni ubuhe bwoko bw'amabara ya plastike agomba kugira?

Hue, urumuri, no kwiyuzuzamo nibintu bitatu byamabara, ariko ntibihagije guhitamoibara rya plastikis gusa bishingiye kubintu bitatu byamabara.Mubisanzwe nkibara rya plastike, imbaraga zaryo zo gusiga, imbaraga zo guhisha, kurwanya ubushyuhe, kurwanya abimuka, kurwanya ikirere, kurwanya ibishishwa nibindi bintu nabyo bigomba kwitabwaho, kimwe n’imikoranire yamabara na polymers cyangwa inyongeramusaruro.
(1) Ubushobozi bukomeye bwo gusiga amabara
Imbaraga zo gusiga amabara bivuga ingano ya pigment isabwa kugirango ubone ibicuruzwa runaka byamabara, bigaragazwa nkijanisha ryimbaraga zo gushushanya byintangarugero isanzwe, kandi bifitanye isano nimiterere ya pigment no gutatana kwayo.Mugihe uhisemo ibara, mubisanzwe birasabwa guhitamo ibara rifite imbaraga zikomeye zo kugabanya ibara ryamabara.

(2) Imbaraga zikomeye zo gutwikira.
Imbaraga zikomeye zo guhisha bivuga ubushobozi bwa pigment yo gupfukirana ibara ryinyuma yikintu iyo ikoreshejwe hejuru yikintu.Guhisha imbaraga birashobora kugaragazwa mubare kandi bingana na misa ya pigment (g) isabwa kuri buri gice cyubuso iyo ibara ryinyuma ryuzuye.Mubisanzwe, ibinyabuzima bidafite ingufu bifite imbaraga zo gutwikira, mugihe ibinyabuzima kama bibonerana kandi bidafite imbaraga zo gutwikira, ariko birashobora kugira imbaraga zo gutwikira iyo bikoreshejwe hamwe na dioxyde de titanium.

(3) Kurwanya ubushyuhe bwiza.
Ubushyuhe bwo kurwanya pigment bivuga ihinduka ryibara cyangwa imiterere ya pigment mugihe cyo gutunganya ubushyuhe.Mubisanzwe, igihe cyo kurwanya ubushyuhe bwa pigment gisabwa kuba 4 ~ 10min.Mubisanzwe, ibinyabuzima bidafite umubiri bifite imbaraga zo kurwanya ubushyuhe kandi ntibyoroshye kubora kubushyuhe bwo gutunganya plastike, mugihe pigment organic ifite ubukana buke.

(4) Kurwanya kwimuka neza.
Kwimuka kwa pigment bivuga ibintu byerekana ko ibicuruzwa bya pulasitike bifite amabara akenshi bihura nibindi bintu bikomeye, amazi, imyuka nibindi bintu, kandi pigment yimuka iva imbere muri plastiki ikajya hejuru yubusa bwibicuruzwa cyangwa ibintu bihura nabyo.Kwimuka kw'amabara muri plastiki byerekana guhuza nabi hagati yamabara.Mubisanzwe, pigment na pigment ngengabuzima bifite amazi menshi, mugihe ibinyabuzima bidafite umubiri bifite amazi make.

(5) Kurwanya urumuri rwiza no guhangana nikirere.
Umucyo hamwe nikirere bivuga amabara atuje munsi yumucyo nibidukikije.Kwihuta kwumucyo bifitanye isano na molekulire yimiterere yamabara.Amabara atandukanye afite imiterere ya molekulire itandukanye kandi yoroheje.

(6) Kurwanya aside nziza, kurwanya alkali, kurwanya solvent no kurwanya imiti.
Ibicuruzwa bya pulasitiki mu nganda bikunze gukoreshwa mu kubika imiti no gutwara imiti nka acide na alkalis, bityo rero aside na alkali birwanya pigment bigomba kwitabwaho.
