mpweya wouma wa Ceramic Clay wogulitsa

Clay ndi dothi lokakamira lokhala ndi tinthu tating'ono pamchenga, ndipo limakhala ndi pulasitiki wabwino pokhapokha madzi atadutsa mosavuta.
Dothi wamba limapangidwa ndi nyengo ya mchere wa silicate padziko lapansi. Nthawi zambiri, limakhala lozungulira mu situ. Tinthu tating'onoting'ono timakulira ndipo mawonekedwe ake ali pafupi ndi mwala wapachiyambi, womwe umatchedwa dongo loyambirira kapena dongo loyambirira. Zomwe zimapanga dothi lamtunduwu ndi silika ndi alumina, zomwe zimakhala zoyera komanso zowoneka bwino, ndipo ndizofunikira kwambiri popangira dongo lanyumba.

Clay nthawi zambiri amapangidwa ndi nyengo ya mchere wa aluminosilicate padziko lapansi. Koma ma diagenesis ena amathanso kupanga dothi. Maonekedwe a dongo munjira izi atha kugwiritsidwa ntchito ngati chisonyezo cha kukula kwa diagenesis.
Clay ndi chinthu chofunikira kwambiri pamchere. Amapangidwa ndi ma silicates osakanikirana ndi mitundu ingapo ya alumina, alkali chitsulo oxides ndi alkaline lapansi zitsulo oxides, ndipo imakhala ndi zosafunika monga quartz, feldspar, mica, sulphate, sulfide, ndi carbonate.
Mchere wamchere ndi wocheperako, nthawi zambiri mumtundu wa colloidal, mu crystalline kapena mawonekedwe osakhala a crystalline, ambiri mwa iwo amawoneka ngati ma flake, ndipo ochepa amakhala ofanana ndi ndodo kapena ndodo.
Mchere wa dongo ndi pulasitiki atanyowetsedwa ndi madzi, amatha kupunduka atapanikizika kwambiri ndipo amatha kukhala osasunthika kwakanthawi, ndikukhala ndi malo akulu. Tinthu timene timayimbidwa mlandu, motero zimakhala ndi kutulutsa thupi koyenera komanso mawonekedwe am'madzi, ndipo zimagwirizana ndi ma cations ena. Kutha kusinthana.
