Common knowledge of coating: the development of anti condensation water heavy-duty anti-corrosion coating for flue gas pipeline

Core tip: generally, there are four types of chimneys: brick chimneys, reinforced concrete chimneys, insulating bricks and steel chimneys The main function of chimney is to pull out the fire and smoke, exhaust the smoke and improve the combustion conditions Under the action of chimney effect, indoor organized natural ventilation and smoke exhaust can be realized, but its negative effects are also various: first, the sand is blown into the room through various holes and gaps in the lower floor, consuming heat and polluting the room; second, the air is pumped from the bottom hall door to the top floor through the elevator shaft, resulting in the elevator door can not be closed normally; Third, when there is a fire, with the rapid rise of indoor air temperature Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Paint Home News: generally, there are four types of chimneys: brick chimneys, reinforced concrete chimneys, thermal insulation bricks and steel chimneys The main function of chimney is to pull out the fire and smoke, exhaust the smoke and improve the combustion conditions Under the action of chimney effect, indoor organized natural ventilation and smoke exhaust can be realized, but its negative effects are also various: first, the sand is blown into the room through various holes and gaps in the lower floor, consuming heat and polluting the room; second, the air is pumped from the bottom hall door to the top floor through the elevator shaft, resulting in the elevator door can not be closed normally; Third, when a fire occurs, with the rapid rise of indoor air temperature, the volume increases rapidly, and the chimney effect is more obvious As the outlet channel of gas and dust, flue gas will be affected by these gases and dust and its service life will be reduced, so people often apply a layer of anti-corrosion coating on the chimney to prolong its service life and save costs The traditional anti-corrosion of chimney is made of light ceramic Although it has the characteristics of light weight, heat insulation and heat preservation, it is easy to fall off because of its high water absorption, low mechanical strength In order to solve this technical problem, especially the corrosion of low temperature flue gas condensate After years of research and development, Beijing Zhisheng Weihua Chemical Co., Ltd has produced a new type of corrosion resistant material zs-1041 smoke anticorrosive coating The high temperature flue gas is resistant to temperature and the low temperature flue gas is resistant to heavy corrosion, which has always been the problem of flue gas pipeline anticorrosion The main components of zs-1041 smoke anti-corrosion coating are nano powder, ceramic bead, silicon carbide, boron nitride, fine-grained alumina, ultra-fine zinc oxide, titanium oxide, etc., which are made into cermet functional filler to improve the wear-resistant and anti-corrosion performance of chimney Zs-1041 is resistant to medium corrosion such as hydrogen sulfide in flue gas, scour, good ductility, acid and alkali resistance Compared with the traditional glass scale anticorrosive coating, it has better ductility and firm adhesion Zs-1041 has super strong adhesion A dense interface transition layer can be formed by coating a thin layer on the inner wall of the chimney Thus, the corrosion of flue gas and dust on the chimney is reduced, the adhesion of coal tar is effectively reduced, the emission of flue gas is favorable, and the temperature resistance of the coating also reaches the domestic anti-corrosion limit of flue gas - 800 ℃, greatly improving the service life of the chimney The smoke anticorrosive coating not only has a long service life and good durability, but also the damaged coating can be easily repaired With the progress of science and technology and the continuous enhancement of people's development concept of "environmental protection, high efficiency, energy saving and consumption reduction", the single capacity of the thermal power generation system in the power industry is becoming larger and larger, and more and more attention is paid to preventing the corrosion and crack of the chimney to ensure the operation safety and service life Zhisheng Weihua smoke anti-corrosion coating is also widely used, which can be applied to various boiler furnace, kiln, flue, chimney, desulfurization equipment and dust removal equipment It involves a wide range of industrial fields It is in the leading position in the domestic anti-corrosion technology level of chimney With continuous improvement, we believe that Zhisheng Weihua flue gas anti-corrosion coating will be the leading coating in the domestic flue gas anti-corrosion industry to better serve the society Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
