Embodiment Construction
[0022] Below in conjunction with all accompanying drawings the present invention will be further described, and preferred embodiment of the present invention is: see appended figure 1 And attached figure 2 , the preparation method of the alumina valve body described in this embodiment, the valve body is formed by composite preparation of component A and component B, and the mass parts of the component A are: 250 parts of α-type alumina ceramic powder; The mass parts of each component of component B are: 3 parts of zirconia, 3 parts of silicon carbide powder.
[0023] Its preparation method is:
[0024] 1) Mix component A and component B according to the ratio and stir evenly, set aside;
[0025] 2) Send the stirred raw materials into a ≥150-ton press for pressing to form a blank for later use;
[0026] 3) Surface treatment is carried out on the original blank, and finally a waterway connection valve blank that meets the needs is formed;
[0027] 4) Send the valve blank in...

The invention provides an alpha-form alumina ceramic valve body and a preparation method thereof. The alpha-form alumina ceramic valve body is obtained by compounding 95%-99% of a component A and 1%-5% of a component B, wherein the component A is alpha-form alumina ceramic powder, and the component B is an auxiliary material. The preparation method comprises the following steps: mixing the component A and the component B in proportion, adding the mixture into a pressing machine, pressing a blank, and carrying out water path, plane and tapping treatments to form a valve blank; and framing the valve blank, adding the framed valve blank into a forming furnace to form a valve body, externally compounding the valve body with a metal shell, and carrying out examination, packaging and ware warehousing. According to the scheme, the alpha-form alumina ceramic valve body has good stability, is pollution free and can meet various performance index requirements such as health, hygiene, environmental friendliness and energy conservation.
Description
technical field [0001] The invention relates to water equipment, in particular to an α-type alumina ceramic valve body for a faucet and a preparation method thereof. Background technique [0002] Water tap is the popular title of water valve, which is used to control the size switch of water flow and has the effect of saving water. The replacement speed of the faucet is very fast, from the old-fashioned cast iron process to the electroplating knob type, and then to the stainless steel single temperature single control faucet, the stainless steel dual temperature dual control faucet, and the kitchen semi-automatic faucet. Now, more and more consumers are choosing faucets, and they will comprehensively consider materials, functions, shapes and other aspects. Existing faucets are made of copper-zinc alloy or stainless steel valve body. After using the metal valve body for a long time, the lead, zinc and mercury in the metal will form secondary pollution to the water, which wil...
