Preparation method of water-soluble ceramic core

[0047] Example 1:A method for preparing a water-soluble ceramic core, the ingredients of the water-soluble ceramic core are as follows: 20%-60% sodium chloride powder, 40%-80% zircon powder, sodium chloride The total weight fraction of zircon powder and zircon powder is 100%, and it is characterized in that: it also additionally includes 0.5%-1% ethyl silicate of the total weight fraction of sodium chloride powder and zircon powder, and 15%-20% Plasticizer, described plasticizer is 50% polyethylene glycol, 30% baking soda, 10% talcum powder;

[0048] The preparation steps of the water-soluble ceramic core include,

[0049] The first step, powder configuration and mixing steps

[0050] Pour 20%-60% sodium chloride powder and 40%-80% zircon powder into the ball mill jar, mix evenly with a ball mill, and after mixing for 2-4 hours, pour the mixed ceramic powder into the pan middle;

[0051] The second step, the step of preparing slurry

[0052] The proportion of the total w...

[0078] Example 2: The difference between this example and Example 1 lies in the weight ratio of sodium chloride and zircon powder: 20% sodium chloride powder and 80% zircon powder. Take 10kg powder weight percentage as an example, sodium chloride powder 2kg, zircon powder 8kg.

[0079] Example 3: The difference between this example and Example 1 lies in the weight ratio of sodium chloride and zircon powder: 30% of sodium chloride powder and 70% of zircon powder. Take 10kg powder weight percentage as an example, sodium chloride powder 3kg, zircon powder 7kg.
