Description

2-port spray gun < RTI ID = 0.0 >

The present invention relates to a two-port spray gun, and more particularly to a two-port spray gun having a plurality of valve seats and needle assemblies in one spray gun body, and being simultaneously atomized in response to a trigger operation.

As the Korean shipbuilding market has shifted from shipbuilding to offshore plants, the requirements of the coating market have been changing.

As the offshore plant is exposed to the ocean for a long time, a higher film thickness is required compared with the ship. In order to secure the thickness of the coating film, a coating process is repeated several times. Therefore, the paint which is dried quickly in order to increase the efficiency of the stacking work and shorten the work process is used.

[0003] Two-pack spray systems for supplying the topcoat paint and the hardener immediately before the spray gun are continuously developed.

The spray gun applicable to the liquid type spray system described above is a spray gun which is sprayed at the same time by mixing and spraying on a spray gun head as in Korean Patent Nos. KR 10-0578274, KR 10-1363553 and US 7,163,160 .

The spray gun has a limitation in controlling the mixing ratio of the main body and the hardener due to the spatial restriction of the head, and the liquid paint is hardened in a short time. When used for a long time, the spray gun is hardened in the spray gun, And the spray gun itself is often discarded.

Therefore, in order to solve the above problems, the present invention is an external mixed painting system in which a subject and a curing agent are sprayed respectively and not mixed in a spray gun, but a subject and a curing agent are mixed immediately before being applied to a coating surface.

The present invention discloses a two-port spray gun applicable to the above external mixed painting system.
