Description
Technical field
The present invention relates to the coating of a kind of ultrathin type for storage tank, the insulation of exterior wall appearance.
Background technology
Along with the acceleration of China's suitability for industrialized production development, greatly facilitate Economic development.First, China has become the first in the world energy consumption big country, and crude oil in China Apparent con-sumption 4.87 hundred million tons in 2013, the Apparent con-sumption of vapour, diesel oil reaches 2.64 hundred million tons.The oil refining enterprise in the whole nation, crude oil, heavy oil, residual oil storage tank are all needed by steam heating, to ensure the mobility of oil product, and the top floating plate of petroleum tank is the main portions of heat loss, but thick and heavy conventional heat preserving method can exceed floating plate load, affect equipment safety operation, a large amount of water and mark coal will be consumed simultaneously.
Secondly, at the vapour line of the enterprises such as chemical industry, metallurgy, electric power, substantially use the heat preserving mode of rock wool, the shortcoming of this heat preserving method is: toxic, sealing joint is poor, heat bridge lose high, pipeline is perishable.As long as and ultrathin thermal insulation coatings 3mm just can reach the effect of rock wool heat-preservation, reducing heat bridge loss, also have good anti-corrosion function, is the innovation substituting the Conventional insulation applied for a long time.
The target that " 12 " planning proposes energy-saving and emission-reduction was: by 2015, the ten thousand yuan of gross domestic product energy consumptions in the whole nation drop to 0.869 ton of standard coal (by calculation of price in 2005), and the 1.276 ton standard coals of 1.034 tons of standard coal decline 16%(than 2010 than 2005 decline 32%)." 12 " period, realize save energy 6.7 hundred million tons of standard coals.The present invention runs mainly for equipment such as oil refining enterprise's crude oil, heavy oil, residual oil storage tank and vapour lines all will consume a large amount of electric power, water, fire coal.The development of ultrathin thermal insulation coatings, for industry energy conservation reduces discharging the Material selec-tion providing high-quality, fractional energy savings reaches more than 45%.
The various crude oil of current China, heavy oil, residual oil storage tank total amount reaches more than 800,000,000 tons, mostly adopt more traditional rock wool, the lagging materials such as silicate, and the good silicon carbide of fire performance or zirconium dioxide be major ingredient and water glass are that the inorganic paint that caking agent is made is incubated, its main Problems existing is: rock wool, the lagging materials such as silicate are moistureproof, water resistance is poor, greatly heat-insulating property is reduced because making moist, to the seriously corroded of tank body, especially coastland, tank body Surgery therapy steel plate also often occurs to be wiped off by high wind, the insulation life-span is short, cannot be incubated at the common lagging material of the floating roof of External floating roof tank, and common inorganic paint is in order to improve heat-insulating property, dope layer at least will more than 8 millimeters, spraying man-hour and material cost higher, two is that this inorganic paint aging speed is fast, and the easy to crack and bubbling of coating, radiation protection ability is lasting, and thermal-insulation coating degradation is fast.
In prior art, heat insulation coating all technical is: heatproof is generally less than 100 DEG C, and acid resistance and alkali resistance time are less than 48 hours.
The present invention has the following advantages relative to existing lagging material
1. to have coating thin for ultrathin exterior wall heat-insulating paint of the present invention, only needs the thickness of 1 ~ 3mm, just can improve the thermo-efficiency of process furnace more than 1.5%;
2. the present invention is in use to the good airproof performance of matrix, and ductility is high, effectively can improve the anti-corrosion function of process furnace outside surface;
3. to have heatproof high for ultrathin thermal insulation coatings of the present invention, can heatproof 150 DEG C, strong adhesion, not easily efflorescence and aging;
4. ultrathin thermal insulation coatings of the present invention, produce, construct simply, do not have potential safety hazard, its environmental-protecting performance is superior.
Summary of the invention
