Application of liangliang insulating colloid to liquefied gas storage tank

The external surface of liquefied gas storage tank should be sprayed with water to reduce its temperature in summer season. This measure not only consumes large amount of industrial water and electric energy, but also brings serious corrosion to tank's surface coating and metal body. To solve this problem, DT-22 Liangliang insulating colloid produced by Shanghai Datong Research Institute is tried out to 10 sets of 100 m³ horizontal liquefied gas storage tank. This product can be painted to tank's external surface directly to realize insulating and temperature reducing efficiency.Compared with red lead antirust paint, Liangliang insulating colloid has good properties of chemical resistance, rust resistance, abrasive resistance and adhesion. When it is painted to liquefied gas tanks, there will be no need to perform water spraying for temperature reducing in summer, thus saves the painting procedure for anticorrosion year by year, and saves maintenance cost and extends tank's life span.
