。Paints containing aggregates, which have been commonly used in the past, have been applied using a spray gun with a hopper (the paint is charged into the hopper) using glass beads calcium carbonate, cinnabar sand, and other aggregates. However, since only a small amount of paint enters the hopper, a lot of preparation is required, which is inefficient.

ある。It is well known that the methods of transporting and supplying paint to the gun head using a pressure tank and the method using a pump have been put into practical use as solutions to these problems. Quantitative properties are poor, and when supplied and transported using low-pressure air, the discharge base fluctuates significantly due to the difference in height of the gun head, making it difficult to control the coating film thickness.

塁の定量性が乏しく、塗装面の仕上りが悪い。．． On the other hand, pumping methods that are estimated to have better quantitative performance than the pumping tank method include snake pumps (mono pumps), rotary pumps (or tubing pumps), and piston pumps, but since they have many emotional parts, It is impractical due to severe wear caused by There are diaphragm pumps on the general market that have less sliding and less wear due to aggregate, but because of the diaphragm, there is a lot of pulsation, poor quantitative discharge, and a poor finish on painted surfaces.

て効果を上げている。Eliminating this pulsation has become a challenge, and there is a need for a pulsation prevention device that is efficient, has good quantitative properties, and can provide a good finish on the painted surface. Pulsation also occurs when general solvent-based paint is transported and supplied using a piston pump, but pulsation is effectively prevented by a hollow cylindrical chamber (generally referred to as a surge chamber) in the transportation supply pipe route. is increasing.

る。In other words, we are considering using a conventional diaphragm pump for aggregate-containing paint, which has good work efficiency, and eliminating the pulsation caused by the diaphragm pump, and preventing pulsation so that the discharge amount can be easily quantified and a uniform finish can be obtained. As a result, they discovered that this could be achieved by making the bottom of the cylindrical chamber used for conventional solvent-based paints hopper-shaped and angled. That is, if the angle of the hopper shape at the bottom of the chamber was 400 degrees or more, preferably 60 degrees or more, the same pulsation prevention effect as in the case of using a cylindrical chamber used in conventional solvent-based paints could be obtained.

量性の良い塗装が出来る。More preferably, even if the pump is operated for a long time, aggregate will not accumulate at the bottom of the chamber, and coating can be performed without pulsation and with good quantitative properties.
