What are the conventional methods of slurry painting?Do you get a uniform coating film? It has the drawbacks that it is extremely difficult to obtain, takes time to paint, and wastes a large amount of paint.

であり、屡々セメント類が多用される。On the other hand, the present invention imparts special properties to slurry paint, and also uses the rotation of the cup at the tip of the coating machine in the centrifugal atomization coating method. The standard 20.000 to 4 Q
, 1 centrifugal atomization coating was successfully achieved at ultra-low speeds ranging from 000 rpm to SOO to 1.50 rpm. In other words, the slurry paint according to the invention has a weight ratio of water as a medium and fine powder suspended in it of 1:2.
By limiting the ratio to 1 to 2.5, and by adding 7% to 10% of the weight of the fine powder to this suspension, water-soluble acrylic resin or water-soluble polyester resin, the slurry becomes This ensures that the most stable and uniform condition can be maintained from the storage tank through the delivery vibrator to the coating nozzle and coating. The fine powder mixed in water is usually a pigment or an inorganic agent for diluting the pigment, and cements are often used.

が大切である。If the ratio of water to fine powder is larger than the above range, the separation of the fine powder will be large, resulting in significant uneven coating on the painted surface, and if it is smaller than the above range, the viscosity of the paint will increase, making it difficult to achieve uniform coating. The amount of water-soluble resin to be added is most appropriately 7% to 10% of the fine powder from the viewpoint of slurry stability and dispersibility. It is also important that the resins added are water-soluble and that they help form a tough film when dried after application.
