With the development of national economic construction, industrial water consumption has increased dramatically. Promotion of industrial refrigeration and cooling tower, waterwould help to save water, protect the environment and reduce energy consumption. Because of this, the demand of domestic cooling towers is increasing year by year. The cooling tower is a large heat exchanger, which is mainly for cooling water of power plant and manufacturing plant; the water is in turn cooling the necessary equipment for daily operation.
Because the structure materials used for the cooling tower must undergo a variety of environments, including chemical and biological invasions and harsh environments, the pultrusion FRP (hereinafter referred to as GFRP) profiles have the characteristics of high strength, light weight, and anticorrosion of FRP, and the pultrusion process and other FRP The production process, such as hand paste or RTM, is highly economical and the material performance is the most stable. Therefore, cooling tower structure is the dominant choice.
The pultrusion GFRP is used for cooling towers to be used as structural materials to compete with wood, concrete, and steel, and in all cases, to provide an unfolding advantage over these materials:
There is no corrosion compared with wood, in addition, Compared with steel and concrete materials, GFRP has good chemical resistance and light weight.
Main structure: square pipe, rectangular pipe, angle steel, plank, I-beam, deck, flat bar, etc.
Nanjing Spare has more than 200 types of moulds that can be used to produce GFRP products for cooling towers.
