with With the development of national economic construction, industrial water consumption has increased sharply. Promote cooling towers, now industrial and refrigeration water It is of great practical significance to save water, protect the environment and reduce energy consumption. Because of this, the demand for domestic cooling towers is increasing year by year. Cooling towers are large heat exchangers, which are mainly used for cooling in power plants and manufacturing plants. Water; this water in turn cools the equipment necessary for daily operation.
Because the structural materials used in the cooling tower must withstand various Various environments, including chemical and biological invasion and harsh environments, because pultruded glass fiber reinforced plastic (hereinafter referred to as GFRP) profiles have the characteristics of high strength, light weight and strong anti-corrosion of glass fiber reinforced plastic, the pultrusion process is different from other glass fiber reinforced plastics. Compared with production processes such as hand lay-up or RTM, it is highly economical and has the most stable material properties, so it is the dominant choice in cooling tower structural parts.
Pultruded GFRP is used as a structural material for cooling towers with Wood, concrete and steel compete and, in all cases, offer uncompromising advantages over these materials:
Compared with wood, there is no biomass corrosion, and fiberglass and resin do not provide microorganisms;
GFRP has good chemical resistance compared to steel and concrete materials;
Light weight compared to structural wood, steel and concrete;
