Problems solved by technology

In my country, due to the low degree of commercialization of casting coatings, most lost foam casting manufacturers lack systematic and in-depth research on the formulation and performance of coatings. In actual production, they are generally prepared for their own use at the production site, resulting in many casting quality problems. , which directly weakens the advantages of precise production of lost foam casting and greatly limits the development of lost foam casting technology

Description

technical field [0001] The invention belongs to the field of casting, and in particular relates to a coating for casting and a preparation method thereof. Background technique [0002] Lost foam casting technology is a precision molding technology that has been widely used at home and abroad. Coating is one of the key technologies of the lost foam casting process, and the quality of the coating directly affects the success or failure of the process. Many literatures disclose that the success of the lost foam casting process depends on the shape 50%, 30% on the coating, and 20% on other process factors. Pay attention to. In my country, due to the low degree of commercialization of casting coatings, most lost foam casting manufacturers lack systematic and in-depth research on the formulation and performance of coatings. In actual production, they are generally prepared for their own use at the production site, resulting in many casting quality problems. , which directly weak...
