Casting Coating
Introduction:
Casting coating refers to a material used to coat the surface of the casting mold or core during the casting process. Its main function is to protect the surface of the casting mold or core from erosion and erosion by high-temperature molten metal. It can also improve the surface quality of the casting and increase the accuracy of the casting.
Product Details
It is composed of refractory powder, carrier, binder and additives. Among them, refractory powder is the main component of the coating, which determines the fire resistance and heat insulation performance of the coating; the carrier is used to mix the refractory powder and binder evenly and make the coating have certain fluidity and coating properties ; The binder is used to bond the refractory powder and the carrier together to form a coating layer with a certain strength and adhesion; the additive is used to improve the performance of the coating, such as fluidity, coating properties, drying speed, etc. .
According to different uses and requirements, casting coatings can be divided into many types, such as sand coatings, core coatings, metal mold coatings, investment casting coatings, etc. Different types of coatings have different properties and characteristics and need to be selected according to the specific casting process and casting requirements.
