The invention mainly aims to provide a glaze, which aims to improve the wear resistance of an archaized brick adopting the glaze as a ground coat.
In order to achieve the above purpose, the glaze provided by the invention comprises the following components in percentage by weight: 20-22 parts of potassium feldspar, 16-18 parts of albite, 18-19 parts of quartz, 8-9 parts of barium carbonate, 4-6 parts of zinc oxide, 4-5 parts of calcined kaolin, 3-5 parts of calcined alumina, 8-9 parts of nepheline powder, 9-11 parts of kaolin and 9-15 parts of zirconium silicate.
In the technical scheme of the invention, the potassium feldspar and the albite are mainly used for melting and wrapping other raw materials in the glaze during firing, so that the formation of a glaze layer is promoted, the pores are reduced, and the transparency is improved. The melting temperature range of the albite is narrower than that of the potassium feldspar, the high-temperature viscosity of the melt is smaller, and the temperature change is quicker, so that the albite can be filled in the pores formed during the melting of the potassium feldspar. And the quartz, the albite and the potash feldspar are melted together to form transparent quartz glass, so that the glossiness of the glaze is improved, the wear resistance is improved, and the hardness of the glaze is improved. The barium carbonate generates uniform small air holes after roasting, so that the occurrence of nonuniform air holes is reduced, and the glaze layer formed by sintering the glaze is compact, so that the hardness and the friction resistance are good, the color is firm and bright, and the barium carbonate is tightly combined with the outer glaze layer of the ground glaze layer sintered by the glaze. The zinc oxide has good fluxing effect in the glaze, so that the formed ground coat has small expansion coefficient and high thermal stability, and the expansion coefficient of the ground coat is conveniently smaller than that of the glaze layer positioned outside the ground coat and larger than that of a ground blank layer, such as a double-peak throwing glaze layer positioned outside the ground coat in the actual firing process, and meanwhile, the luster and whiteness of the glaze surface are increased, and the elasticity of the glaze is improved. The calcined kaolin can improve the chemical stability and strength of the sintered glaze layer, thereby ensuring the wear resistance of the glaze layer. The calcined alumina is used for improving the wear resistance of the fired glaze layer in the technical scheme because of high hardness and good wear resistance. The nepheline powder has high expansion coefficient, so that the blank glaze combination property of the ground coat layer and the ground blank layer can be adjusted, and the glaze combination property of the ground coat layer and the glaze layer positioned outside the ground coat layer, such as a bimodal glaze throwing layer, can be also adjusted. The kaolin can raise the melting temperature of the glaze and make the glaze water not easy to precipitate. Zirconium silicate is used for improving the water resistance and wear resistance of the glaze, and improving the combination of the green body and the glaze. The firing range of the ground coat layer is wide, and the color development is stable.
In some embodiments of the present invention, the chemical composition of the glaze includes: siO (SiO) 2 62.0～64.0％、Al 2 O 3 23.2～25.2％、Fe 2 O 3 0.2～0.3％、TiO 2 0.10～0.15％CaO 1.8～2.5％、MgO 0.82～0.95％、K 2 O 4.95～5.20％、Na 2 O 1.51～2.20％、ZnO 2.05～2.55％、BaO 5.02～5.88％、Zr(Hf)O 3.0～5.0％、B 2 O 3 <0.05％、SrO 0.01～0.03％、Rb 2 O 0.02～0.03％、P 2 O 5 0.2～0.3％。
In the technical scheme of the invention, the chemical components of the glaze can be obtained through analysis after the glaze is burnt. SiO in glaze 2 Derived from quartz, and K derived from potassium feldspar and sodium feldspar 2 O and Na 2 O forms transparent quartz glass. Al (Al) 2 O 3 The wear resistance of the ground coat formed by the glaze can be improved by the calcined kaolin, the kaolin and the calcined alumina, so that the wear resistance of the glaze layer which is tightly combined with the ground coat and is positioned outside the ground coat is improved. The barium oxide is derived from barium carbonate, and uniform small pores are generated after roasting, so that the non-uniformity is reducedThe appearance of uniform large pores makes the glaze layer formed by sintering the glaze compact, so the glaze has good hardness and friction resistance, and the color is firm and bright, and is tightly combined with the external glaze layer of the ground glaze layer sintered by the glaze.
