According to the national standard requirement of GB/T3532-2009, the thermal stability and appearance texture of the invention examples 1-5 and comparative examples 1-5 are compared and detected. The specific detection results are as follows:
TABLE 6
Through comparison, the invention can find that the use amount of feldspar is reduced by introducing calcined kaolin to the SiO in the glaze 2 And Al 2 O 3 The mass ratio of the components is controlled within 4-6, so that the glaze surface can obtain the required glossiness and texture; and has excellent thermal stability. All the products of examples 1, 2 and 5 showed no cracking even at high temperature, and only a small amount of cracks were observed on the surface of 1 product of examples 3 and 4. While comparative examples 1-5 glaze SiO 2 And Al 2 O 3 The mass ratio of the glaze to the powder is 8-10, and the product obtained by adopting the traditional preparation process of the relief texture glaze is far inferior to the embodiment in thermal stability, and the glaze is in a molten state and has no obvious granular texture. In comparative example 1, cracks appeared on the surface of the product at 140 ℃; compared with the comparative examples 3-5, the cracks are more serious under the condition of 140 ℃; in the comparative examples 1-5, cracks appear on the surface of the product under the conditions of 160 ℃ and 180 ℃.
As can be seen from FIG. 1, the product prepared by the embodiment of the invention has the advantages that the surface of the glaze material forms the relief with uniform size, and the overall glaze surface has moderate and soft luster. Referring to fig. 2, the glaze of the products obtained in comparative examples 1 to 5 has a smooth surface, and the glaze has no sense of relief and does not form reliefs with uniform size.
The research shows that the calcined kaolin is introduced to reduce the consumption of feldspar and effectively adjust SiO 2 And Al 2 O 3 The mass ratio of (A) to (B) can ensure that the glaze surface obtains the required glossiness and textureMeanwhile, the expansion coefficient of the glaze is also controlled, so that the fired glaze surface cannot crack, and the thermal stability meets the national standard requirement of GB/T3532-2009. The glaze is glazed by adopting a one-time glaze spraying method, the glaze firing is finished by one-time glaze firing, the thickness of the glaze is not required to be increased for forming the relief, the relief with uniform size is formed on the surface of the glaze, the process problems of twice glazing and twice glaze firing of the traditional relief texture glaze are solved, the process is simple and easy to operate and control, the glaze of the prepared product is moderate and soft in gloss, the artistic effect is strong, the hand feeling is rough but not harsh, the product quality is stable, and the glaze is suitable for industrial batch production.
It should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the technical solutions, and those skilled in the art should understand that the technical solutions of the present invention can be modified or substituted with equivalent solutions without departing from the spirit and scope of the technical solutions, and all should be covered in the claims of the present invention.
