Description
Technical field
The present invention relates to Industrial Stoves radiant heat absorbent utilizes field, more particularly to a kind of high temperature High Radiant Rate Coating.
Background technology
Between 800～1300 DEG C, radiant heat transfer accounts for more than 85% to high temperature furnace.The spary infrared radiation coating on the inwall of Industrial Stoves, can improve the blackness of kiln inwall, increase radiant heat transfer effect, and heat exchange in reinforcing kiln makes body of heater radiate and declines, and has the advantages that energy saving, improves the thermal efficiency, extends converter life.As material science and technology constantly develops, some are widely used in development infrared radiation coating with the material compared with high IR spectral emissivity, to improve the radiance of body surface, reach the purpose of augmentation of heat transfer.
The many documents at home and abroad delivered and several infrared radiation coatings have been recorded in patent, the multiplex oxide of its aggregate (powder), but oxide emissivity itself is not high.From the point of view of the existing state's rustproof lacquer in market, the ET-4 of such as Britain, the CRC1100 of Japan, 1500 coating, emissivity is relatively low, and decays with the rising of temperature；The poor adhesive force of coating, easily comes off, and result in product service life and shortens.Therefore how to design the emphasis that a kind of coating material of the radiant heat absorbent of effectively suitable Industrial Stoves is research.
The content of the invention
The technical problem to be solved in the present invention is to provide the strong high temperature High Radiant Rate Coating of a kind of high temperature resistant, emissivity height, adhesive force.
The high temperature High Radiant Rate Coating of the present invention, including the water that weight portion is 30-40, dispersant NP-10 of the weight portion for 0.3-0.5, Ludox of the weight portion for 30-40, organic silicon emulsion of the weight portion for 4-8, granularity kaolin 500 mesh more than of the weight portion for 5-10, weight portion for 5-10 granularity in 500 mesh above aluminum oxide, granularity nickel oxide or nickel protoxide 500 mesh more than of the weight portion for 10-15.
Its making step is：Water of the weight portion for 30-40 is placed in container, weight portion is added for the dispersant NP-10 of 0.3-0.5, Ludox of the weight portion for 30-40, after being uniformly mixed, addition weight portion is kaolin of the granularity of 5-10 more than 500 mesh one by one, weight portion for 5-10 granularity 500 mesh above aluminum oxide and weight portion for 10-15 nickel oxide or nickel protoxide of the granularity more than 500 mesh, latter is added after previous being uniformly mixed, continue to be uniformly mixed after adding, add the organic silicon emulsion that weight portion is 4-8, it is further continued for being uniformly mixed, obtain final product high temperature High Radiant Rate Coating.
The present invention novelty be：There is provided one kind can high temperature resistant, emissivity is high, dirt-resistant slagging scorification, high-temperature corrosion resistance is wear-resistant, do not fall off, play drum, long service life, can preferably meet various petroleum and petrochemical industry heating furnaces and various generator tubes, furnace lining, the high temperature High Radiant Rate Coating of the design requirement of associated components on the products such as industry kiln road furnace lining, electric heater unit radiation heating tube.
