Mwala wa Gaoling ndi mchere wofunika kwambiri wopanda chitsulo. Kaolin yomwe imapangidwa pophwanya, kupukutira ndi kusungunuka ili ndi zinthu zambiri zabwino kwambiri, ndipo yakhala ikugwiritsidwa ntchito kwambiri m'mafakitale ambiri, makamaka m'makampani opanga utoto. Pakadali pano, mtengo wa zinthu wamba za kaolin wokhala ndi calcium ndi wotsika, koma mphamvu yake yophimba si yabwino, zomwe zimalepheretsa kugwiritsidwa ntchito kwake m'munda wa utoto wapamwamba. Izi zikusonyeza kuti ndi kukula kwa tinthu tating'onoting'ono, mphamvu yophimba ya kaolin yokhala ndi calcium imawonjezeka pang'onopang'ono, chifukwa chachikulu ndichakuti tinthu tating'onoting'ono ta kaolin, mphamvu yophimba imakhala yayikulu.Kupukusira kwa Kaolinndi chipangizo chopangira chomwe chimagwiritsidwa ntchito pokonza kaolin ya 300-1250 ultra fine kuti chiwongolere mphamvu yake yophimba. Kodi ubwino wake ndi wotani? Lero ndi wopanga mphero ya kaolinGuilin Hongcheng kwa inu chiyambi chatsatanetsatane.

Pambuyo pophwanya, kupukuta ndi kuyeretsa kwambiri, 850℃ calcination, yomwe imapereka chidziwitso chothandiza pakugwiritsa ntchito ndi kukonza kwambiri kaolin ya dongosolo la malasha. Chifukwa cha kuchuluka kwa silicon ndi aluminiyamu, kaolin ndi yofooka komanso yovuta kuvala. Imafunika kukhala yosalala (sefa ya 325 mesh 5% ~ 10%), ndipo mphero wamba ya Raymond singathe kupeza phindu lalikulu potengera kusalala kumeneku.
