Advantages Of Using FRP Tanks In Power Plant Water Treatment Operation

FRP Tanks

Water treatment engineering water treatment is generally divided into pure water treatment, circulating water treatment and raw water wastewater treatment.  FRP has been widely used in water treatment engineering because of its high specific strength, excellent corrosion resistance and non-corrosion characteristics.  With the promulgation of national environmental protection, energy conservation and emission reduction policies and laws and regulations, the state will increase investment in this field, and the application of FRP/ composite materials in water treatment facilities will make great progress.

1) Classification and introduction of FRP tanks  

Glass fiber reinforced plastic water tank is divided into vertical and horizontal mechanical winding FRP tank, FRP transport tanks, glass fiber reinforced plastic tanks, all kinds of chemical equipment, glass fiber reinforced plastic horizontal tank, vertical storage tanks, transport tanks, vessels and large series of containers, according to the (storage or transportation) used in epoxy furan resin, modified or polyester resin and phenolic resin as binder,  It is composed of high resin content corrosion-resistant lining layer, impermeable layer, fiber winding reinforcement layer and outer surface protection layer.  

2) Advantages and characteristics  

FRP products have excellent physical properties and higher specific strength than steel, cast iron and plastics.  Thermal conductivity is only 0.5 of steel, with good thermal and electrical insulation experience.  FRP products have great design flexibility and excellent wall structure performance.  The working temperature of the product is between -50 ℃ and 200℃, and the pressure is generally below 6.4mpa.  It has the advantages of pressure resistance, corrosion resistance, aging resistance and long service life.  With light weight, high strength, anti-seepage, heat insulation, heat preservation, non-toxic, smooth surface and so on.  Mechanically wound glass fiber reinforced plastic containers can adjust the physical and chemical properties of products by changing the resin system or using different reinforcement materials to meet the needs of different media and working conditions.  Different pressures were designed by structural layer thickness, winding Angle and wall thickness.  It is a fiber winding composite material with remarkable characteristics.  

3) Application scope  

It can be widely used in petroleum, chemical industry, textile, printing and dyeing, electric power, transportation, food brewing, artificial synthesis, water supply and drainage, seawater desalination, irrigation and national defense engineering and other industries.  Storage of all kinds of corrosive media can withstand all kinds of acid, alkali, salt and organic solvents.  Mainly used in petroleum, chemical, pharmaceutical, printing and dyeing, brewing, water supply and drainage, transportation and other industries.  Suitable for hydrochloric acid, sulfuric acid, nitric acid, formaldehyde, methanol can also be used for storage and transportation of various products, such as alcohol, hydrogen peroxide, sewage, sodium hypochlorite, etc., can also be used as underground oil tanks, thermal storage tanks, transport tankers, etc.
