FRP cooling tower before use preparation and maintenance
FRP cooling tower before the use of the preparation and operation of the maintenance, in order to make the FRP cooling tower can play the best function, so as to extend the life of the FRP cooling tower, then good inspection and maintenance must be done. Under normal conditions, it is necessary to make a comprehensive observation of FRP cooling tower every day to ensure its normal operation.
FRP cooling towers need to be thoroughly inspected and cleaned while working. And the part of the work needs to be examined in more detail, and can not be carried out until there are no problems. After passing through the inspection door and entering the tower, it is necessary to clean the debris and silt on the bottom basin of the cooling tower, and check whether the pipes are blocked. High pressure water is used to wash the soil on the bottom basin of the cooling film and cooling tower, and the waste water is discharged through its outlet. It is also necessary to check whether the wiring of the motor is correct. Check the tightness of the belt in the belt drive equipment of the FRP cooling tower. Check whether the rotation of the fan is more flexible and so on. Glass fiber reinforced plastic cooling tower internal modification: the use of high-performance resin matrix, reinforced fiber additives, improve the quality of glass fiber. This method is costly. FRP products due to its poor weather resistance, wear resistance, low hardness limited its application, and the market needs good appearance, cost-effective FRP products. There are two ways to solve the defects of FRP products: internal modification and surface coating. Surface coating: in the molding process or after the molding of FRP products, use a variety of different materials with high performance or a specific function to modify, protect or give new functions to the surface, improve the quality and competitiveness of products.
Surface high quality, multi - functional, without changing the formula of FRP products, process conditions. Most of the FRP surface coating protection by painting or spraying gelcoat and other simple methods, but the quality is poor, and requires regular maintenance. And the surface protection of high performance glass reinforced plastic (FRP) refers to the coating technology with high decoration, heavy anticorrosion, super weathering resistance, functional and convenient construction.
High performance FRP surface protection has the following requirements: coating (environmental protection) : water - based coating, powder coating, high - solid and solvent - free coating; Six factors to consider when choosing paint: coating purpose, working environment, construction conditions, adherence to the "economy" principle, compatibility and environmental protection requirements. At present, the surface coating technology of FRP with development prospect is as follows: leaching is suitable for small and neat workpiece; And spraying is suitable for large surface area, neat shape of the workpiece. The coating surface quality of FRP products is good and the investment is not high.
