Problems solved by technology

[0002] The electric rice cooker on the market now mainly uses the aluminum pot liner, and the toxic paint commonly known as Teflon coated on the surface of the aluminum pot liner, this kind of Teflon paint will slowly fade after a period of use. Falling off means that the life of the aluminum pot liner is also over

Embodiment 1

[0013] (1) Preparation of the ceramic body of the ceramic inner pot

[0014] Weigh according to the following proportions: 30% spodumene, 20% Guangxi white clay, 5% petalite feldspar, 20% Guizhou washing mud, 6% corundum, 6% magnesia clay, 13% black soil, fired at 1290°C The ceramic body of the ceramic pot liner is obtained, the water absorption rate is less than 0.5%, and the cold and heat shock is water quenched at 500°C-20°C.

[0015] The specific production process: mixing ball mill → squeezing mud → refining mud → rolling forming → drying → billet trimming → firing → ceramic pot inner pot ceramic body.

[0016] (2) Preparation of the inner wall of the ceramic liner pot

[0017] Weigh according to the following ratio: petalite 70%, talc 7%, spodumene 6%, zinc oxide 6%, Suzhou soil 5%, barium carbonate 6%, according to the ball: material: water=1.5: 1:0.6 After ball milling and crushing to a certain particle size, the low-expansion anti-fouling glaze water on the inner wa...

Embodiment 2

[0021] (1) Preparation of the ceramic body of the ceramic inner pot

[0022] Weigh according to the following proportions: 40% spodumene, 15% Guangxi white clay, 8% petalite feldspar, 18% Guizhou washing mud, 4% corundum, 5% magnesia clay, 10% black soil, fired at 1290 °C The ceramic body of the ceramic pot liner is obtained, the water absorption rate is less than 0.5%, and the cold and heat shock is water quenched at 500°C-20°C.

Abstract

The invention discloses a preparation method of a far-infrared ceramic liner for an electric rice cooker. According to the preparation process, a low-expansion spodumene-based ceramic liner body is firstly prepared, wherein the ceramic liner meets rapid cooling and rapid heating in the range of 500 DEG C-20 DEG C, and the water absorption rate is less than 0.5%. The preparation process of the ceramic liner body comprises the steps of mixing and ball-milling; mud squeezing; mud stirring; rolling and forming; drying; trimming; and firing, then glaze firing with a low-expansion inner glaze, and coating with an ordinary coating outside to obtain the ceramic liner. The far-infrared ceramic liner for the electric rice cooker, prepared according to the preparation method disclosed by the invention, can be widely used for replacing aluminum liners of the electric rice cookers; the ceramic liner has the advantages that the surface which is in contact with foods is environment-friendly and durable, and the ceramic liner has a far-infrared radiation function after being heated; when the ceramic liner is used for cooking rice and other foods, a certain through heating effect is realized, so that the heating of the rice is uniform and thorough, and the rice has relatively good shape, taste and fragrance.

Description

technical field [0001] The invention relates to the technical field of production of ceramics, far-infrared ceramics and electric rice cookers, in particular to a preparation method of a far-infrared ceramic liner for electric rice cookers. Background technique [0002] The electric rice cooker on the market now mainly uses the aluminum pot liner, and the toxic paint commonly known as Teflon coated on the surface of the aluminum pot liner, this Teflon paint will slowly fade after a period of use. Falling off means that the life of the aluminum pot liner is also over. The far-infrared ceramic liner pot for the electric rice cooker prepared by the method of the invention can replace the aluminum pot liner in the electric rice cooker currently on the market. Compared with the aluminum pot inner pot, the advantage of the ceramic inner pot is that the inner wall of the ceramic inner pot is made of ceramic glaze, which is non-toxic, harmless, environmentally friendly and durable,...
