Problems solved by technology

The molecular formula of spodumene is Li 2 O·Al 2 o 3 4SiO2 2 Adding spodumene to the raw materials of ceramic products can greatly improve the heat resistance of ceramic products. It can be used for electric heating and open flame heating without cracking when dry burning. Therefore, it can be used as tableware and cooking utensils. , such as Chinese patent 99109029.2 "a high-strength heat-resistant lithium porcelain catering utensil" and 200510023142.0 "a high thermal shock-resistant ceramic and its manufacturing method" are all such products, but they are all ordinary ceramic products or catering utensils, not Purple sand ceramic products, while ordinary purple sand is difficult to achieve the above characteristics

Embodiment 1

[0025] Embodiment 1: Make purple sand pottery soup pot liner, or rice pot liner, blank: meet the requirements of each raw material purple sand soil 5, aluminum clay 19, spodumene 30, clinker 5, talcum powder 5, kaolin 15, Bauxite 15, magnesia clay 6;

[0026] Glaze: this mud 30, that is, the mud made from the above-mentioned raw materials, clinker 19, loess 15, frit 12, iron red 7, water glass 2, lithium feldspar 15.

[0027] Production method: the billet is made into shape, and the raw materials of each component are selected and added to the ball mill according to the above ratio requirements to mix, wet ball milled for about 12 hours, put into the slurry tank and fully stirred, and passed through a 100-mesh sieve, and the spodumene is discharged Add it to the ball mill for the first 4 hours and pass through a 40-mesh sieve. Then press filter until the water content is about 20% to form a raw material mud, put the raw material mud into the warehouse and stale for 10 days, e...

Embodiment 2

[0030] Example 2 Making soup pot liner, raw materials: purple clay 6, aluminum clay 15, spodumene 30, clinker 5, calcined talcum powder 4, kaolin 15, bauxite 19, magnesia clay 5 iron red 1 ;

[0031] Glaze: 29 clay, 20 clinker, 15 loess, 13 frit, 6 iron red, 1.85 water glass, 15 lithium feldspar, 0.15 sodium tripolyphosphate.

[0032] Production method: the blank is wet ball milled through a 120-mesh sieve; the glaze is passed through a 380-mesh sieve, sodium tripolyphosphate is first added to the ball mill and water glass is added 5 hours before the end of the ball mill.

Embodiment 3

[0033] Example 3 Making an inner pot of an electric cooker, raw materials: purple clay 8, aluminum clay 10, calcined spodumene 32, clinker 5, bauxite 15, calcined talcum powder 2, ash 8, kaolin 10, magnesium quality sticky 10;

Abstract

The invention discloses a heat-resistant purple sand ceramic tool. The manufacture material includes stock and glaze; wherein, the stock is formed by the following components according to weight percentage: 1 to 15 percent of purple sand soil, 25 to 38 percent of triphane, 5 to 30 percent of bauxite clay, 5 to 30 percent of kaolin, 2 to 6 percent of talc, 5 to 20 percent of alum clay, 5 to 20 percent of grog and 5 to 25 percent of attaclay; the glaze is formed by the following components according to weight percentage: 20 to 35 percent of paste, 10 to 25 percent of petalite, 15 to 25 percent of grog, 8 to 15 percent of clinker, 12 to 25 percent of yellow earth, 6 to 9 percent of iron red, 0 to 0.15 percent of trimeric sodium phosphate and 1 to 2 percent of water glass. The adoption of triphane in the material of ceramics can largely enhance the heat-resistant capability, and the ceramics can be heated by electricity or fire and even the firing without water causes no crack. The heat-resistant purple sand ceramics can be adopted either as tableware or as drinking vessel.

Description

Technical field: [0001] The invention relates to a purple sand pottery, in particular to a heat-resistant purple sand pottery in terms of daily life dining utensils. Background technique: [0002] Purple sand is a kind of silicate mineral, mainly composed of quartz powder ore and clay minerals glued to it. Unlike ordinary pottery, purple sand has a double pore structure. Purple sand ore contains silicon oxide, aluminum oxide, iron oxide, Calcium oxide, magnesium oxide, manganese oxide, sodium oxide, potassium oxide, etc. The molecular formula of spodumene is Li 2 O·Al 2 o 3 4SiO2 2 Adding spodumene to the raw materials of ceramic products can greatly improve the heat resistance of ceramic products. It can be used for electric heating and open flame heating without cracking when dry burning. Therefore, it can be used as tableware and cooking utensils. , such as Chinese patent 99109029.2 "a high-strength heat-resistant lithium porcelain catering utensil" and 200510023142....
