What are the corrosion resistance and wear resistant materials of the FGD system in thermal power plants?
Energy saving: good lubricity, low running resistance loss and save running cost. The lining wall of the desulfurization lining is as smooth as a mirror, the absolute roughness is only Ra0.02668, and the rubber lining has good self lubrication and good adhesion performance, and the running resistance is about 20% smaller than that of the ordinary steel tube, so that a large amount of power can be saved.
The range of temperature adaptation is wide. The lining pipe of desulfurization lining can be used for a long time in the range of -40 degrees C to +140 degrees C, and the lining layer will not be separated from the steel frame due to the change of temperature.
Excellent corrosion resistance: our company adopts lining rubber, chemical performance is very stable, can withstand most corrosive medium and organic solvent erosion, than polyethylene, polypropylene, nylon, ABS and other plastic more corrosion resistance. In addition to strong oxidizing acid, in a certain range of concentration and temperature resistant to various corrosive medium (acid, alkali, salt and organic medium (naphthalene), except) 30 days dipping in 80 kinds of organic solvents in 20 degrees and 80 degrees in appearance without any abnormal phenomenon, and other physical properties are few almost no change.
High strength, high impact resistance: rubber elastomer (1.2g/cm3) low density, light weight, with vibration performance and excellent resistance to mechanical shock absorption, good high strength, good rigidity, no creep, impact resistance, earthquake resistance, anti water hammer performance, convenient transportation, installation and maintenance.
Desulfurization means that the sulfur in coal is fixed with calcium and other solids to prevent formation of SO2 when burning. Lining pipe characteristics of lining rubber desulfurization pipe:1.: the fine structure of reinforced skeleton steel and rubber layer with high performance adhesive composite as a whole pipe, using a special process by the company of professional equipment vulcanization composite vulcanization molding, overcomes the disadvantages of pressure resistant steel tubes do not wear, wear plastic and rubber pressure and impact brittle glass steel poor performance, also have the common advantage steel and wear resistant rubber, synthetic performance excellence.2. good wear resistance, long service life: abrasion test results in 0.03 ~ 0.20 cm3/1.61km range is about 3 ~ 5 times of plastics, wear resistance than steel high 4-6 times.
