COATING METHOD USING LNG TANK POLYURETHANE FORM AUTOMATIC COATING DEVICE

摘要

A coating method of using the LNG storage tank polyurethane foam coating machinery apparatus is provided to minimize the waste of original material by effectively using two-part adhesive and form the uniform coating face. A coating method of using the LNG storage tank polyurethane foam coating machinery apparatus comprises the following features of: an inside tank(1) manufactured into steel material; a outer tank(2) that surrounds the inside tank and is manufactured into concrete; a runway beam(10) installed in the circular-arc form along the upper edge of a heated-insulating hole of a LNG storage tank; a gondola(20) moving horizontal or up and down along the runway beam and being set at the runway beam; a spray gun(30) being installed at gondola and spraying two-part adhesive after mixing; two part type pumps(40) supplying the two-part adhesive to the spray gun through respective distinct supply lines; two reservoirs(50) separately storing the two-part adhesive and connected to two part type pump and to respective distinct supply lines; and a booster pump(60) installed at reservoir and supplying the two-part adhesive to two part type pump through the distinct supply lines.
