example 1

[0014] (1) Add brass powder with a mass percentage of 5-30% of the mass of the raw material to the raw material with far-infrared function, ball mill the mixture mixed with the brass powder, and mix it uniformly. (2) Add the coke powder screened to the mixture obtained in step (1) with a mass percentage of 5-30% of the mass of the mixture, and then mix evenly. (3) The binder polyvinyl alcohol is dissolved in water, the addition of polyvinyl alcohol accounts for 1~20% of the mass percentage composition of water, then puts a small amount of guiding agent Glauber's salt into the polyvinyl alcohol aqueous solution, stirs 1 ~2 hours. (4) Put the mixture obtained in the step (2) into the solution obtained in the step (3), and the plasticity of the clay after refining and stale is very good. The prepared mud is pressed or molded into various shapes, and then dried. (5) Putting the blank obtained in step (4) into a tunnel kiln for firing at a firing temperature of 1200-1400° C. and ...

example 2

[0016] The preparation method of double-layer far-infrared ceramic plate 1 of the present invention, concrete steps are as follows: 1) add mass percent content to the raw material with far-infrared function and account for 5~30% brass powder of raw material quality, will be mixed with brass powder The mixture was ball milled and mixed evenly. 2) To the mixture obtained in step 1), add the coke powder pore-forming agent that has been screened and whose mass percentage accounts for 5-30% of the mixture mass, and then mix evenly. 3) Use water-soluble mirabilite as a guide agent, use viscous water-soluble polyvinyl alcohol as a binder, and dissolve polyvinyl alcohol in water. The amount of polyvinyl alcohol added accounts for the mass of water. 1-20% of the percentage content, then put a small amount of Glauber's salt into the above solution, and stir for 1-2 hours. 4) Put the mixture obtained in step 1) into the solution obtained in step 3), and after smelting and aging, press i...

Abstract

The invention discloses preparation methods of a porous far-infrared ceramic material and a two-layer far-infrared ceramic plate. The preparation method of the porous far-infrared ceramic material comprises the following steps: (1) adding metal powder or alloy powder in the raw material with a far-infrared function, then performing ball milling, and mixing evenly; (2) adding coke powder in the mixture obtained in the step (1), and mixing evenly; (3) dissolving sticky water-soluble organic matters in water, adding a small amount of soluble salt in the obtained solution, and stirring evenly; (4) placing the mixture obtained in the step (2) in the solution obtained in the step (3), refining mud, aging, pressing or performing plastic moulding to obtain the blanks with various shapes, and drying; and (5) placing the blanks obtained in the step (4) in a tunnel kiln to fire. The porous far-infrared ceramic material produced by the method has high strength; and the surface of the material is difficult to burst and weather. The preparation methods are characterized by simple production process and the like. The prepared two-layer far-infrared ceramic plate is arranged on a gas stove to realize flame-free combustion. The bottom of a pot can directly contact with the surface of the burner and be heated.

Description

Technical field: [0001] The invention relates to a preparation method of a porous far-infrared ceramic material and a double-layer far-infrared ceramic plate. Background technique: [0002] Household gas stoves sold on the market are divided into direct-fired gas stoves and infrared gas stoves. There are no sales of infrared gas stoves at all in large home appliance supermarkets, only direct-fired gas stoves are sold. Direct-fired gas stoves have a large market share, while infrared gas stoves have a small share. I know that the combustion efficiency of the infrared gas stove is at least 20% higher than that of the direct-fired gas stove, and the energy-saving effect is obvious; the harmful gas produced by the gas combustion of the infrared gas stove is less than that of the direct-fired gas stove, and it is an environmentally friendly gas stove . Infrared gas stoves are not much more expensive than direct-fired gas stoves. Why are there so few sales of infrared gas stov...
