China Coatings Online News Information
the most energy-saving insulation materials, thermal insulation coatings are divided into thermal insulation coatings to prevent thermal conduction and thermal reflection insulation coatings, the two coatings in the oil tank oil depot has a very good protective effect, fire and explosion prevention, reduce fuel consumption, energy saving significantly.
1, to prevent thermal conduction of thermal insulation coatings
insulation insulation coatings to solve the high temperature of the oil tank area fire and explosion prevention problems, oil tank area accidental high temperature fire conditions, to solve the pipe fire and explosion prevention is an urgent problem, to avoid greater disasters. In modern chemical production, the fire insulation in the reservoir oil reservoir is one of the important means to prevent fire explosion accidents, according to the heat transmission process of the closed air insulation layer, through the extreme analysis, the optimal insulation layer thickness formula to make the vertical air layer insulation effect is best, using high temperature insulation coating construction fire prevention. ZS-1 high temperature insulation coatings, modern technology insulation insulation factors under the outstanding representative, ZSWH nano-scale thermal insulation materials, low thermal conductivity, construction flexibility, improve industrial upgrading and other advantages. Domestic multi-functional insulation coating main research and development institutions and production units, the production of ZS-1 heat-resistant insulation coating, paint thermal conductivity of 0.03W/m.K, temperature resistance of 2000 degrees C, in 1100 degrees C of the surface of the object coated with 8mm thick, the surface temperature of the object can be reduced to less than 100 degrees C. ZS-1 heat-resistant insulation coating is applied to the reservoir, fire retardant, thermal insulation, energy saving and consumption reduction, insulation wear level can be achieved the best, reduce the high temperature heat and high temperature flame reduce the impact on the oil reservoir, reduce chemical safety accidents.
2, thermal reflection insulation coating
oil storage tank is the storage of oil containers, it is the main equipment of oil depots, the common tank shape is generally vertical cylindrical, horizontal cylindrical, spherical and so on.
Because of the long-term leakage of oil storage tanks in the summer sun, high temperature environment, resulting in a rapid rise in its surface and internal temperature, most of the heat concentrated on the surface of the oil interface, speeding up the evaporation of oil, resulting in oil loss and overpressurization hazards. Insulation coating research and development personnel for a long time on the storage tank sun protection and cooling tracking research found that in hot summer, the outside surface temperature of the reservoir can reach 65 degrees C, internal boost up to 1800Pa, high pressure through the P/V valve drain paint concentration can reach 40% one 60%.
The sun's rays are light emitted by the "burning" of the sun's nuclear reaction, which shoots at a long distance to the Earth, then filters through the atmosphere to the ground, and the infrared energy in the sunlight that crosses the atmosphere and reaches the ground accounts for about 55% of the total energy, followed by visible light for about 45% and ultraviolet light for less than 1%. The sun shines 15 minutes of energy on the ground, enough for the world to use for a year, human direct use of solar energy mainly solar heating, solar hot water system, solar heating room, solar power generation and other ways. However, the sun shines on a specific object of our human beings, the continuous solar heat will also cause certain harm, in the summer, buildings, oil tanks, granary, plant workshop these objects, long-term exposure to the sun, the internal temperature of the object will be high, to the object inside the people, oil, food, machinery and equipment will bring some harm, if the temperature reaches a certain limit is, will also produce great damage.
tank reservoir in the open environment, ground oil tank due to sun exposure, resulting in a rapid rise in its surface and internal temperature, most of the heat concentrated on the surface of the oil interface, which led to accelerated oil volatilization. With the development of national economy and science and technology, more and more people pay attention to energy conservation and environmental protection. At present, the commonly used insulation methods are the use of insulation layer, metal coating and water spray cooling. To glass cotton, foam composed of insulation layer, although there is a certain insulation effect, but once the heat energy into the interior, even if the external temperature is reduced, the heat energy still can not be emitted. In order to reduce the temperature of the surface of the tank, it is required to often cool the water on it, and the inner and outer walls of the spray pipe are prone to rust. Therefore, the development of a new type of reflective insulation coating to save energy, protect the environment, is of great significance. ZS-211 reflective insulation coatings can effectively change this situation.
with the development of national economy and modern science and technology, the energy saving and environmental protection of oil storage tanks have been paid more and more attention, and the current commonly used methods of sun protection and insulation of oil storage tanks are using insulation layer and water spray cooling. According to the design requirements of PetroChina, Sinopec and other storage oil enterprises, research and development of ZS-221 sunscreen insulation coatings, modified thermal insulation coatings are a set of reflection, radiation, infrared shielding and hollow microbead insulation and one of the new insulation cooling coatings, coatings can High reflection of solar infrared, visible and ultraviolet light in the 400nm-2500nm range, and new inorganic materials such as nanotubes, carbides and nitrides in coatings, with strong electromagnetic wave infrared shielding and resistance Aging does not allow the sun's heat to accumulate heat on the surface of the object heating up, in the hot summer, direct sunlight, the outside surface of the reservoir insulation cooling can reach more than 25 degrees C, even on rainy and cloudy days can also be cooled to more than 5 degrees C, paint added to the new inorges Anti-aging materials, weather resistance to aging increased by 30%, ZS-221 sunscreen insulation coating service life can reach more than 25 years, paint water-based environmental protection and energy-saving, no flash point, is the oil storage tank sun insulation the best energy-saving materials.
