Kaolin, cyane cyane ultra-nziza ibarwa kaolin, nkibintu byingenzi cyane bidafite ingufu zidasanzwe, buri gihe byagize uruhare runini mubikorwa byimpapuro nibintu byiza byumubiri.Kaolin ibarwa ikoreshwa mu nganda zimpapuro ni ibintu byinshi kandi byera byera byubaka, bikoreshwa cyane mugusimbuza dioxyde ya titanium ihenze hamwe nizindi pigment zo mu rwego rwo hejuru.Nkumukora ibikoresho byo gusya ,.kubara kaolinultra-nziza ihagaritserollerurusyo yakozwe na HCMilling (Guilin Hongcheng) yakoreshejwe cyane kandi iramenyekana mugukora kaolin ibarwa.Ibikurikira nintangiriro yuburyo bwo gukora bwa calcine yabazwe:

Ibisabwa byujuje ubuziranenge bwinganda zimpapuro kuri kaolin ibarwa byerekanwe cyane cyane mubisabwa kugirango ingano yubunini, umweru, imbaraga zihishe, kwinjiza amavuta, kwibumbira hamwe, agaciro ka pH, kwambara agaciro nibindi bipimo bya kaolin yabazwe.Mu bihe isoko rya kaolin isanzwe yogejwe ryagiye rigabanuka uko umwaka utashye bitewe n’ingaruka za karubone ya calcium iremereye, igurishwa ry’isoko ryarazamutse, bituma inganda nyinshi zikurikiza.Kuva mu myaka ya za 1980, havumbuwe umubare munini w'amakara ya kaolin (bivugwa ko ibiteganijwe kuzarenga toni miliyari 10).Kubera ubwiza bwayo hamwe n’umwanda muke wangiza, urukurikirane rwamakara kaolin rwabaye ibikoresho byiza byokubyara umusaruro wimpapuro zo kubara impapuro zibarwa kaolin.Isoko ryisoko rya kaolin ibarwa ikomoka kumurongo wamakara kaolin ni ngari.

Umusaruro wo kubara kaolin ubarwa urimo ibice bibiri: guhonyora superfine inzira no kubara inzira yera.

1. Gusya superfine yuburyo bwo kubara kaolin uburyo bwo gukora: gusya superfine inzira ni ihuriro ryingenzi kugirango umenye ubwiza bwa kaolin.Kumenagura urukurikirane rw'amakara kaolin superfine ni kaolin ikomeye (kuva 5 ~ 20mm kugeza 40 ~ 80 μ m) Ultrafine (kuva 40 kugeza 80 μ M kugeza - 10 μ M cyangwa - 2 μ m)。kubara kaolinUruganda rwa Raymond hamwe na kaolin ya calcine vertical roller uruganda rwakozwe na HCMilling (Guilin Hongcheng) ni ibikoresho byo kumenagura bikabije, bishobora gukoreshwa muburyo bwo guhonyora mbere yuburyo bwo kubyaza umusaruro kaolin, kandi bishobora gutunganya amakara ya 80-600 mesh;Urukurikirane rwa HLMX rwabaze kaolin ultra-nziza ihagaritserollerurusyo, urusyo rwa roller hamwe nibindi bikoresho byo kumenagura ultra-nziza bikwiranye no gukonjesha ultra-nziza muburyo bwo gukora kaolin yabazwe, ishobora gutunganya ifu ya 3-45 μ M superfine kaolin ifu ni uruganda rwiza rwa kaolin superfine.

2. Uburyo bwo kubara no kwera uburyo bwo kubara kaolin yabazwe: Urebye ibiranga diagenetike biranga amakara yamakara ya kaolin, ni ukuvuga ko arimo ibintu bimwe na bimwe kama, kuburyo amabuye yacyo yera ari 6 ~ 40% gusa, bikaba biri kure. byujuje ubuziranenge bwibikorwa byinganda zikora kaolin, bityo rero kubara decarburisation no kwera bigomba gukurikizwa.Ukurikije ibisabwa bitandukanye kugirango ubuziranenge bwa kaolin, burashobora kandi kugabanywamo ibicuruzwa bibiri: ubushyuhe buciriritse bwabazwe kaolin hamwe nubushyuhe bwo hejuru bwabazwe kaolin.

Kugereranya uburyo bwo kubara uburyo bwa kaolin bwabazwe: ukurikije niba inzira ya superfine ari inzira itose cyangwa inzira yumye hamwe nurutonde rwibikorwa bya superfine hamwe no kubara, inzira enye zibyara umusaruro zirashobora guhuzwa, aribyo

.Kuberako abantu bafite imyumvire itandukanye yibikoresho byiza cyane, inzira zinzira zikoreshwa mubigo bitandukanye ziratandukanye:

.

(2) Kubara no gusubiramo ibintu byiza cyane bisaba ibikoresho byihariye byo kumisha nibikoresho byo gutatanya.Iyi nzira ifite intege nke zo guhuza nibikoresho fatizo, ariko irashobora gutanga ibicuruzwa bisabwa ninganda zimpapuro;

.

Muri rusange, inzira ya superfine yumye mbere yo kubara ifite imbaraga zifatika zifatika, kandi igishushanyo mbonera cyerekana ni: ubutare mbisi → kumenagura → kumenagura → superfine yumye → kubara → ibicuruzwa.Ibyiza byiki gikorwa ni: (1) inzira ni ngufi, kandi inzira yose isaba ibikoresho bitatu kugeza bine gusa.Niba HongchengHLMX yabaze kaolin ultrafine ifu yifu hatoranijwe, ibikoresho bitatu gusa birakenewe, aribyo, gusya, kubara kaolin ultrafine yifu yifu, calciner, byoroshye kubuyobozi rusange no guteganya neza;(2) Gukoresha ingufu birumvikana.Muri ubu buryo, uburyo buhebuje bwibikoresho bushyirwa mbere yo kubara kugirango wirinde ikibazo cyo gukoresha ingufu nyinshi kubera kumenagura no gutwika ibikoresho.Niba ifu yo kubara ifu yemewe, irashobora gufatwa nkigikorwa cyuzuye cyumye.Kubijyanye n'ikoranabuhanga, gukoresha ingufu birumvikana.

Gukoresha urukurikirane rw'amakara kaolin kugirango ubyare urwego rwo kubara kaolin mu nganda zimpapuro, nta gushidikanya ko ari inzira nziza yo gukoresha neza amakara y’amakara.Twabibutsa ko inzira zikwiye zigomba gutoranywa ukurikije umutungo waho nigishoro.Niba ushaka kumenya byinshi kubyerekeranye nuburyo bwo kubyaza umusaruro ibikoresho byo guhitamo kaolin yabazwe, nyamuneka uduhamagarire ibisobanuro birambuye.
