The performance characteristics of fin tube thermal anti-corrosion coatings

Fin tube is to improve heat exchange efficiency, usually through fins on the surface of the heat exchange tube, increase the surface area (or internal surface area) of the heat exchange tube, so as to achieve the purpose of improving heat exchange efficiency, such a heat exchange pipe. Fin tube as a heat exchange element, long-term work in the high temperature flue gas operating conditions, such as boiler heat exchanger with fin tube use environment is harsh, high temperature and high pressure and in a corrosive atmosphere, thermal conductive thermal anti-corrosion coating experts pointed out that this requires fin tube should have a high performance index. 1), anti-corrosion performance (Anti-corrosion); 2), wear resistance (Anti-wear); 3), low contact heat resistance; 4), high stability (HigherStability); 5), anti-ash.
Fin tube radiator principle is to cool air by refrigerant, or heat air with heat media, or with cold water to recover air residual heat, such as heat exchange device in the main equipment, into high temperature water, steam or high temperature thermal oil can heat air, into salt water or cold water cooling air. High technical content, research and development of protective sail share coating, coating curing good coating conduction coefficient (70 degrees C) can reach 50w/m.k, coating black body thermal radiation coefficient can reach 0.922, heat exchange ratio is not Brushing acid-resistant thermal anti-corrosion coating substyl material can be improved by more than 10%, conductivity of 10-12S/m or more, that is, equivalent to the volume resistivity of 1012 sm with semiconductor-to-conductor properties of the coating. Corrosion resistance: Except for aggressive oxidizing acids that are resistant to strong acids, alkalis and organic solvents at 600 degrees C. Acid-resistant thermally conductive coatings have been used in a variety of industrial fields, such as electronics, electrical appliances, aviation, chemicals, printing, military and civil.
coating of thermal conductive anti-corrosion coating will protect the cooling metal from the external corrosive substances, in the heat dissipation to speed up the thermal conduction on the basis of the role of protective materials. It plays an anti-corrosion effect on metal thermal materials and extends the life of metal use, and heavy anti-corrosion coating refers to a kind of anti-corrosion coating which can be applied in a relatively harsh corrosive cooling environment and has a longer protection period than conventional anti-corrosion coatings.
thermal anti-corrosion coating, is a fine anti-corrosion coating, anti-corrosion thermal function, high performance requirements. The company develops and sells thermal anti-corrosion coatings mainly concentrated on the outer or inner walls of oil tanks and pipes or in the petrochemical field in the use of heat exchangers less. Mainly because a variety of anti-corrosion coatings have their limitations, some can withstand high temperature corrosion but not heat, some can conduct heat but not oil, some have a short service life. Heat-conducting anti-corrosion coatings select high conduction of film-forming solution and high heat transfer, high heat radiation fillers, cured coating conduction coefficient (70 degrees C) can reach 50w/m.k, coating black body thermal radiation coefficient can reach 0.92, heat exchange rate than no brushed acid-resistant thermal corrosion-resistant coating base material can be increased by more than 10%, some materials can be increased by more than 50%. And has excellent heat resistance and corrosion resistance, can resist acid, alkali, salt solution and organic solvent corrosion, the maximum operating temperature can reach 750 degrees C. The thermal expansion coefficient of acid-resistant thermal anti-corrosion coating is high, and the expansion and contraction of the coating can be consistent with the temperature repeatedly, so as not to produce cracks and shedding. The ceramic functional filler composed of various components of acid-conducting thermal anti-corrosion coating, in collaboration with each other, gives the coating excellent wear resistance, heat impact resistance, can be long-term resistance to cavitation liquid erosion friction and powder friction.
