If the strength of the paint used in bauxite lost foam casting is insufficient, you can try the following treatments:
1.Adjust the formulation: Check the formulation of the paint, you may need to adjust the ratio or type of additives to increase the strength of the paint. Try adding reinforcing agents, binders, or gelling agents, etc.
2.Optimized curing conditions: Ensure that the coating is sufficiently cooled and cured during the curing process to ensure that the coating forms a strong structure. Adjust the curing temperature and curing time appropriately to achieve optimal performance.
3.Increase the coating layer: Consider applying multiple layers of paint to the surface of the mold and curing layer by layer to improve the overall strength of the coating.
4.Use reinforcing materials: Adding some reinforcing materials, such as fibers, microbeads, etc., can effectively increase the strength of the coating.
5.Heat treatment: After the paint has cured, heat treatment can be considered to improve the strength of the paint through heat treatment.
6.Change the paint brand or manufacturer: If you still can't meet the required strength requirements after many attempts and adjustments, you can consider changing the paint brand or looking for products from other manufacturers.
It should be noted that the above treatment methods may vary according to the specific situation, and it is best to operate under the guidance of a professional.
