GUN SPRAYER TO SPRAY HIGHLY REACTIVE COMPOSITIONS Russian patent published in 2010 - IPC B05B7/04 

FIELD: process engineering.

SUBSTANCE: invention relates to construction mechanisation and serves to seal joints and apply coatings onto construction structures from polymer materials resulted from polymerisation of two and more fluid components mixed and fed to coated surfaces in the form of cone consisting of gas and fluid component. In compliance with this invention, gun sprayer circular chamber distributing compressed gas is formed by the casing outer cylindrical wall and union nut inner part. Casing outer wall is cylindrical. Conical inner wall represents reverse truncated cone that makes mixing chamber with the nozzle. Union nut is made from material that features anti-adhesion properties, while said casing is made from material with wear resistant properties.

EFFECT: simple design, higher reliability and ease of operation.
