Kaolin, ibuye ry'agaciro ritari iry'icyuma, ni ubwoko bw'ibumba n'ibumba rigizwe ahanini n'amabuye y'ibumba ya kaolinite. Bitewe n'uko isa n'umweru kandi yoroshye, izwi kandi nk'ubutaka bwa Baiyun. Ibice by'ingenzi ni trioxide ya aluminiyumu na dioxyde ya silikoni

Kaolini yayo nziza ni umweru, yoroshye kandi yoroshye mu miterere yayo, ifite imiterere myiza y’umubiri n’imiti nko kuba plastike no kwirinda umuriro. Ibigize imyunyu ngugu yayo ahanini bigizwe na kaolinite, halloysite, hydromica, illite, montmorillonite, ndetse n’imyunyungugu nka quartz na feldspar.

Ibiranga inzira:

1. Umucyo w'umweru Umucyo w'umweru - Umucyo ni kimwe mu bipimo by'ingenzi by'imikorere ya kaolini, kandi kaolini ifite isuku nyinshi ni umweru. Umucyo w'umweru wa kaolini ugabanyijemo umweru karemano n'umweru wa kalisine. Ku bikoresho fatizo bya ceramic, umweru nyuma yo gukaraba ni ingenzi cyane, kandi uko umweru wa kalisine uba mwinshi, ni ko ubwiza burushaho kuba bwiza.

2. Ingano y'uduce - Ingano y'uduce yerekeza ku gipimo (kigaragazwa mu ijanisha ry'ibice) by'uduce turi muri kaolini karemano mu bwoko butandukanye bw'uduce duhoraho (bugaragazwa muri milimetero cyangwa meshi ya mikorometero). Buri shami ry'inganda rifite ibisabwa byihariye ku bunini bw'uduce n'ubunini bwa kaolini mu ntego zitandukanye. Leta Zunze Ubumwe za Amerika zisaba ko kaolini ikoreshwa nk'igitambaro igira ibipimo biri munsi ya 2 μ m (meshi 6250), ingana na 90-95%, kandi ibikoresho byo gukora impapuro bifite ibipimo biri munsi ya 2 μ m bigira 78-80%. Ku bijyanye n'ibikorwa byo gucukura bisaba gucukura vuba, kwihuta mu gusya, no kwihuta mu gusukura amazi, ni ngombwa kongera ubunini bw'uduce tw'ibice.

3. Guhagarika: Guhagarika no gukwirakwiza bivuga imiterere ya kaolini bigora kuyigwamo iyo ikwirakwijwe mu mazi. Bizwi kandi nka anti flocculation. Uko ingano y'uduce duto, niko guhagarara neza. Kaolini ikoreshwa mu nganda za enamel isaba imiterere myiza yo guhagarika. Imikorere yo guhagarika icyitegererezo gikwirakwijwe mu mazi muri rusange igenwa n'umuvuduko wayo wo kuruhuka mu gihe runaka.

4. Gukingira amashanyarazi: Kaolin nziza cyane ifite ubushobozi bwo gukingira amashanyarazi, ishobora gukoreshwa mu gukora ibumba rikoresha amashanyarazi menshi n'ibumba ridafite insinga. Urwego rw'imikorere y'ibumba rikoresha amashanyarazi rushobora gupimwa bitewe n'ubushobozi bwayo bwo kwihanganira kwangirika kw'amashanyarazi.

Ishyirwa mu byiciro:

Kaolin yogejwe n'amazi ya kaolin ya calcium

Ikoreshwa:

Kaolin ifite uburyo bwinshi bwo kuyikoresha, ikoreshwa cyane cyane mu gukora impapuro, ibumba, n'ibikoresho birwanya ubushyuhe, hanyuma hagakurikiraho gusiga irangi, irangi rya emel, n'ibikoresho fatizo bya sima yera. Mu rugero ruto, ikoreshwa mu nganda nka pulasitiki, amarangi, irangi, amapine, amapine yo gusya, amakaramu, amavuta yo kwisiga ya buri munsi, isabune, imyenda, peteroli, imiti, ibikoresho by'ubwubatsi, nibindi.
