    water-cooled wall is the main heating part of the boiler, which consists of several rows of steel pipes, distributed around the boiler furnace. Its interior is flowing water or steam, the outside world accepts the heat of the flame of the boiler furnace, accelerates the heat absorption pipe wall heat increases, improves the use of heat, in order to solve the water-cooled wall heat exchange pipe, heat exchanger, heat transfer pipe, high temperature mold, cracking pipe, heater, heat sink and other equipment devices, not only in the high temperature acid and alkali medium corrosion resistance but also have a good heat transfer. Based on the high heat transfer and infrared strong thermal radiation of the coating coating, the research and development personnel have developed acid-resistant thermal anti-corrosion coatings that are resistant to high temperature, acid-base and high heat-absorbing heat, speed up the heat absorption of water-cooled walls, improve heat utilization, and protect the material from corrosion.
    thermal conductive anti-corrosion coating will protect heat-absorbing metals from the outside corrosive substances, on the basis of heat absorption to speed up thermal conduction, play a protective material role. It plays a role in anti-corrosion of metal heat-absorbing materials and extends the life of metal use, and heavy anti-corrosion coating refers to a type of anti-corrosion coating that can be applied in a relatively harsh corrosion-absorbing environment and has a longer protection period than conventional anti-corrosion coatings. Newly developed coating, coating curing good coating conductivity (70 degrees C) can reach 50w/m.k, coating black body thermal radiation coefficient can reach 0.92 x, heat exchange rate than no coating acid-resistant thermal corrosion-resistant coating substation material can be increased by more than 10%, conductivity in 10-12S/m or more, that is, equivalent to the volume resistivity of 1012 sm with semiconductor-to-conductor properties. 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.
    thermal anti-corrosion coating, is a fine anti-corrosion coating, anti-corrosion thermal function, high performance requirements. Thermal anti-corrosion coatings are mainly concentrated on the outer or inner walls of oil tanks and pipes or are used less in heat exchangers in the petrochemical field. 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. Acid-resistant thermal anti-corrosion coatings composed of a variety of components of ceramic functional fillers, in collaboration with each other to give the coating excellent wear resistance, heat impact resistance, can be long-term resistance to cavitation liquid erosion friction and powder friction, accelerate heat absorption of acid-resistant thermal anti-corrosion coatings to become a protective energy-saving weapon.
