Kaolin, yomwe imadziwikanso kuti dongo la ku China, ndi mchere wofewa wa aluminosilicate wopangidwa ndi miyala yolemera mu feldspar. Umadziwika kwambiri chifukwa cha makhalidwe ake apadera: kuyera kwambiri komanso kuwala, kukula kwa tinthu tating'onoting'ono, kusungunuka bwino, kuchepa pang'ono, kusakhala ndi mankhwala, kufalikira bwino, kuonekera bwino, komanso kukhuthala kokhazikika. Makhalidwe apaderawa amapangitsa kaolin kukhala chinthu chosasinthika chodzaza ndi zinthu zopangira m'mafakitale ambiri.

Kupanga mapepala kukupitilirabe kugwiritsidwa ntchito kwambiri, komwe kumawerengera pafupifupi 29% ya zomwe zimagwiritsidwa ntchito padziko lonse lapansi. Kaolin imawonjezera kuwala kwa mapepala, kuonekera bwino, kusalala, komanso kusindikizidwa mosavuta, imagwira ntchito ngati chophikira chofunikira komanso chodzaza. Zida zadothi zimatsatira kwambiri pafupifupi 38% ya zomwe zimafunidwa; kaolin imapangitsa kuti mapangidwe, mphamvu, ndi kuyera zikhale bwino mu porcelain, ziwiya zaukhondo, matailosi, ndi zida zadothi zapamwamba zikhale bwino. Imagwiritsidwanso ntchito kwambiri mu utoto ndi zophimba kuti iwonjezere mphamvu yobisala, kukana nyengo, komanso kulimba.

Ntchito zina zazikulu ndi monga fiberglass, rabala, mapulasitiki, zomatira, zoyeretsera, zodzoladzola, mankhwala, ndi mankhwala oyeretsera madzi otayidwa. Ma calcined, otsukidwa ndi madzi, komanso osinthidwa pamwamba amakwaniritsa zofunikira zamafakitale zapamwamba kuti agwire bwino ntchito komanso azikhala olimba.

Msika wapadziko lonse wa kaolin ukukula pang'onopang'ono mu 2026. Zambiri zamsika zikuwonetsa kuti msika udzafikaMadola a ku America 4.61 biliyoni mu 2026ndi5.3% CAGRmpaka 2034. Kuchuluka kwa zinthu kukuyembekezeka kufika pa matani 49.46 miliyoni mu 2026, kukula pa 4.24% CAGR kufika pa matani 60.87 miliyoni pofika chaka cha 2031. Zinthu zazikulu zomwe zikuyambitsa vutoli ndi monga kukwera kwa ndalama zogwirira ntchito, kukwera kwa kufunika kwa mapepala ndi ma CD, chitukuko chapamwamba cha zinthu zopangidwa ndi ziwiya zadothi, komanso kusintha kwa zipangizo zamafakitale zomwe siziwononga chilengedwe.

M'chigawo, Europe ili ndi gawo lalikulu pamsika, pomweAsia-PacificNdi dera lomwe likukula mofulumira kwambiri, lotsogozedwa ndi China, India, ndi Southeast Asia, chifukwa cha mafakitale ndi kukula kwa mizinda. Opanga akuyang'ana kwambiri pa kaolin yoyera kwambiri komanso yosinthidwa kuti igwire magawo amtengo wapatali.

Popeza kaolin ndi mchere wokhazikika komanso wosinthasintha, chiyembekezo cha nthawi yayitali cha kaolin chikadali cholimba. Kukonzanso ukadaulo ndi kugwiritsa ntchito kwatsopano popanga zinthu zobiriwira, mphamvu zatsopano, ndi kuteteza chilengedwe zipitiliza kukweza kufunikira kwake padziko lonse lapansi komanso kufunika kwake pamsika.
