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...

Embodiment 1

[0034] Prepare the faucet in the following order of steps:

[0035] (1) Select 10 parts of raw talc, 70 parts of calcined cooked talc, 15 parts of clay, and 5 parts of BaCO 3 Additives are mixed (above all are weight and number ratio);

[0036] (2) Calcining the above-mentioned mixed raw materials to 1350° C., then grinding with a ball mill for 30 hours, and sieving to obtain a 270-mesh ultrafine powder;

[0037] (3) Take the paraffin wax with a weight of 18% of the powder weight and heat it to melt the paraffin wax into a liquid, then gradually add the powder to the paraffin wax solution, stir while heating, and mix the two evenly to make a slurry. Control the temperature around 60°C;

[0038] (4) Make the uniformly mixed slurry into a faucet shell blank of a specified shape through a hot die-casting process;

[0039] (5) Calcining and dewaxing the faucet shell blank, then polishing the surface, and finally glazing to make a semi-finished product;

[0040] (6) Finally, th...
