Yashi Mai Girma
Yashi mai laushiwani nau'in kayan aluminosilicate ne da ake amfani da shi sosai a masana'antar yin kayan gini.
Babban Sinadarin Sinadari:
Babban sinadaran da ke cikin yashi mai laushi sune Aluminum Oxide (Al₂O₃) da Silicon Dioxide (SiO₂). Jerin sinadaran da aka saba amfani da su sune: 42% ≤ Al₂O₃ ≤ 47% da 51% ≤ SiO₂ ≤ 53%. Hakanan yana ɗauke da ƙananan adadin Iron Oxide (Fe₂O₃), Alkali Metal Oxides (Na₂O+K₂O), da sauran abubuwan da ba su da alaƙa.
Tsarin Samarwa:
Yawanci ana samar da yashi mai laushi ta amfani da ma'adanai masu ɗauke da aluminosilicate, kamar su kaolin, yumbu mai tauri, ko muscovite. Tsarin ya ƙunshi niƙa kayan da aka yi amfani da su, haɗa su da ƙari, da kuma matse su cikin siffarsu. Sannan ana sanya waɗannan siffofi a cikin tanda mai zafi a zafin jiki tsakanin 1300°C da 1550°C. Bayan niƙa, ana niƙa samfurin, ana tantance shi, ana raba shi da maganadisu don cire ƙarfe, da sauran hanyoyin samun samfuran yashi mai laushi iri-iri.
Bayanin Girman Barbashi:
Yashi mai siffar mullite yana samuwa a cikin nau'ikan girman barbashi daban-daban. Babban kayanmu ya haɗa da: raga mai siffar 8-16, raga mai siffar 16-30, raga mai siffar 30-60, raga mai siffar 60-80, da raga mai siffar 80-120. Bugu da ƙari, muna bayar da ƙananan maki da aka sani da foda mai siffar mullite, kamar raga mai siffar 200 da raga mai siffar 300.

Babban aikin simintin daidai shine kera harsashin mold (tsarin shafa tsarin kakin zuma da yadudduka da yawa na kayan da ba sa jurewa don ƙirƙirar harsashi na waje. Bayan tsarin kakin ya narke, ana samar da rami don zuba ƙarfe mai narke). Ana amfani da yashi mai laushi galibi a matsayin tarin da ba sa jurewa a cikin harsashin mold kuma ana amfani da shi akan layuka daban-daban na harsashin, musamman kamar haka:
1. Ƙwallon Sama (Yana ƙayyade Ingancin Filin Siminti kai tsaye)
Aiki:Layin saman yana da alaƙa kai tsaye da simintin kuma dole ne ya tabbatar da kammala saman da santsi (yana guje wa tsatsa da kuma ɓarna) yayin da kuma yake jure tasirin farko na ƙarfen da aka narke.
