Kaolin ni amabuye y'agaciro atari ubutare, ubwoko bw'ibumba n'ibumba ryiganjemo amabuye y'agaciro ya kaolinite.Kubera ko cyera kandi cyoroshye, nanone cyitwa ubutaka bwera.Yiswe Umudugudu wa Gaoling, Umujyi wa Jingde, Intara ya Jiangxi.

Kaolin yacyo yera ni umweru, yoroshye kandi yoroshye ibumba risa, kandi rifite imiterere myiza yumubiri nubumashini nka plastike no kurwanya umuriro.Ibigize imyunyu ngugu bigizwe ahanini na kaolinite, halloysite, hydromica, illite, montmorillonite, quartz, feldspar nandi mabuye y'agaciro.Kaolin ifite uburyo butandukanye bwo gukoresha, bukoreshwa cyane cyane mu gukora impapuro, ububumbyi n’ibikoresho bivunika, bigakurikirwa no gutwikirwa, kuzuza reberi, glaze ya enamel hamwe n’ibikoresho fatizo bya sima yera, hamwe n’amafaranga make akoreshwa muri plastiki, amarangi, pigment, gusya ibiziga, amakaramu, kwisiga buri munsi, isabune, imiti yica udukoko, ubuvuzi, imyenda, peteroli, imiti, ibikoresho byubwubatsi, ingabo zigihugu ndetse nizindi nzego.
Ububiko bwera
Kwera ni kimwe mu bintu nyamukuru byerekana imikorere ya tekinoroji ya kaolin, naho kaolin ifite isuku nyinshi ni umweru.Umweru wa kaolin ugabanijwemo umweru karemano na cyera nyuma yo kubara.Kubikoresho byibanze bya ceramic, umweru nyuma yo kubara ni ngombwa, kandi hejuru yo kubara kwera, nibyiza.Ikoranabuhanga ryububumbyi riteganya ko gukama kuri 105 ° C aribwo buryo bwo gutanga amanota yera yera, naho kubara kuri 1300 ° C nicyo gipimo cyo kubara cyera.Umweru urashobora gupimwa na metero yera.Imetero yera ni igikoresho gipima kwerekana urumuri rufite uburebure bwa 3800-7000Å (ni ukuvuga Angstrom, 1 Angstrom = 0.1 nm).Muri metero yera, gereranya no kwerekana icyitegererezo kigomba kugeragezwa hamwe nicyitegererezo gisanzwe (nka BaSO4, MgO, nibindi), ni ukuvuga agaciro keza (urugero, umweru 90 bisobanura 90% byerekana ko icyitegererezo gisanzwe).

Umucyo ni ibintu bitunganijwe bisa n'umweru, bihwanye no kwera munsi ya 4570Å (Angstrom) imirasire yumucyo.

Ibara rya kaolin rifitanye isano ahanini na okiside yicyuma cyangwa ibinyabuzima birimo.Mubisanzwe, irimo Fe2O3, ikaba itukura n'umuhondo wijimye;irimo Fe2 +, ifite ubururu bwerurutse n'icyatsi kibisi;irimo MnO2, yijimye;irimo ibintu kama, bifite ibara ry'umuhondo, imvi, ubururu, n'umukara.Kubaho kwumwanda bigabanya umweru usanzwe wa kaolin, kandi imyunyu ngugu ya fer na titanium nabyo bigira ingaruka kumweru ubarwa, bigatera ikizinga cyangwa inkovu muri farufari.
