AI Technical Summary

Problems solved by technology

Traditional fine pottery products usually have shortcomings such as poor impact resistance and low thermal shock resistance. The flexural strength is generally around 30MPa, and the rapid cooling and rapid heating performance is between 150°C and 20°C. It is easy to cause damage due to collision during transportation and loading and unloading
All in all, the above problems have become the bottleneck of the development of fine pottery enterprises, and it has been difficult to meet the needs of production development and market application

Abstract

The invention relates to a bending-resistant and heat-shock-resistant far-infrared fine pottery blank, a bend-resistant, heat-shock-resistant far-infrared fine pottery product and a method prepared therefrom, and belongs to the technical field of daily-use ceramics. The anti-bend and heat-shock resistant far-infrared fine pottery billet includes a green body base material and a green body additive, and the green body base material includes the following components in terms of mass percentage: 10-20wt% of Dehua elutriation slurry, 15% of burnt gemstone ~25wt%, china clay 10~20wt%, water washing mud 15~30wt%, potassium albite feldspar 10~25wt%, boronite 1~3wt%, raw talc washing mud 10~20wt%, lithium feldspar 1~2wt% , each green body base material is 100% in total; relative to the green body base material, the addition amount of the green body additive is 3-8wt% of the green body base material. The fine ceramic product has high flexural strength, good thermal stability and far-infrared emission function, which can meet the high-end requirements of consumers.

Description

technical field [0001] The invention belongs to the technical field of daily-use ceramics, and in particular relates to a bending-resistant and heat-shock-resistant far-infrared fine pottery blank, and a bend-resistant and heat-shock-resistant far-infrared fine pottery product and method prepared therefrom. Background technique [0002] Fine pottery is pottery glazed on white or light-colored blanks. It is formed by plastic method, grouting method or semi-dry pressing method, and glazed after bisque firing. Generally, the glaze firing temperature (1060-1150°C) is lower than the biscuit firing temperature (1240-1280°C). It is also made by the "one-time firing" method without bisque firing before glazing. According to the properties of the body, it can be divided into hard fine pottery and soft fine pottery, and according to the use, it can be divided into daily fine pottery and building sanitary fine pottery. There are decorative patterns on fine pottery, and there are als...
