Manufacturing technology of ceramic water tap housing

Abstract

The invention relates to a manufacture art for a housing of a ceramics tap, which is prepared according to the following steps: firstly 10 to 20 portions of raw talcum, 60 to 70 portion of ripe talcum, 10 to 15 portion of clay, 5 to 10 portion of TiO or BaCO3 or the mixture of the two to carry through mixing are prepared and mixed together; then the original mixed raw materials can be calcined to 1320 to 1390 degrees, rubbed for 28 to 36 hours and then sifted to get ultrafine powder with 250 to 300 meshes; then the powder can be added into a paraffin liquid, the weight of which is 15 to 20 percent of that of the powder to make slurry; then the slurry can be shaped into a roughcasts of tap shells in required shape through an injection moulding technics forming technology; then roughcasts can be calcined, dewaxed, polished and glazed; finally roughcasts can be calcined to 1280 to 1350 degrees and cooled naturally. The invention can not generate any pollution during the manufacture and using processes and the product has the advantages of high temperature resistance, abrasion resistance, rust resistance and light weight, etc.

Description

technical field [0001] The invention relates to a manufacturing process of a faucet shell, in particular to a manufacturing process of a ceramic faucet shell. Background technique [0002] Most of the faucet shells (also known as water supply valves) widely used in the market are metal products, especially cast copper and cast zinc alloy coating products. The manufacturing process of these metal products consists of the following steps in sequence: raw material preparation, hot die casting molding , Rough blank grinding, surface plating, accessories assembly. Many sources of pollution will inevitably be generated during the entire manufacturing process, for example, a large amount of dust pollution will be generated during rough grinding, which will bring certain harm to manufacturing personnel and the environment, and a large amount of sewage and heavy metals will be generated in the electroplating process, which will have a great impact on the environment. The environment...

Problems solved by technology

Using this method to manufacture the faucet shell, the water inlet and outlet channels and the threaded parts of the interface cannot be formed in the faucet shell at the same time, so it is necessary to bond the other made water inlet and outlet channels and the threaded parts of the interface in the faucet shell, and the bonding process is complicated. , and because the bonding parts need to use chemical adhesives, it is prone to aging phenomena during use, which is prone to problems such as water leakage and water accumulation in the cavity, which will affect the service life and cause a certain degree of domestic water pollution

In addition, the above method can only be used to make some thick faucet shell products, and the manufactured faucet shell has low material strength, thin wall and low impact resistance.
