is divided into thermal insulation coatings that prevent heat transmission and thermal reflection insulation coatings, the two coatings in the oil tank oil depot has a very good protective effect, reduce fuel loss, energy saving significantly.
1, to prevent thermal conduction of thermal insulation coatings:
insulation insulation coatings to solve the high temperature in the oil tank area fire and explosion prevention problems, oil tank area unexpected 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 storage tank oil reservoir fire insulation is one of the important means to prevent fire explosion accidents, according to the heat transmission of closed air insulation, through extreme analysis, derived the best thermal insulation layer thickness formula to make vertical air layer insulation effect, using Zhisheng Weihua 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. China Environmental Protection Industry Association member unit Beijing Zhisheng Weihua Chemical Co., Ltd., is the main research and development and production units of multi-functional insulation coatings, the production of ZS-1 heat-resistant insulation coatings, coating thermal conductivity of 0.03W/m.K, temperature resistance of 1800 degrees C, in 1100 degrees C of the surface of the object coated 8mm thick, the surface temperature of the object can be reduced to less than 100 degrees C. The storage tank oil depot is coated with ZS-1 Zhisheng heat insulation coating, fire retardant, insulation, energy saving and consumption reduction, insulation wear level can achieve the best, reduce high temperature heat and high temperature flame reduction on the oil reservoir oil depot impact, reduce chemical safety accidents.
2, thermal reflection insulation coating:
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. Beijing Zhisheng Weihua insulation coating research and development personnel long-term sun protection and cooling of oil storage tanks tracking research found that in hot summer, the outside surface temperature of the storage tank can reach 65 degrees C, internal boost up to 1800Pa, high pressure through the P/V valve drain

concentration can reach 40% 160%.
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. The ZS-211 reflective insulation coating produced by Beijing Zhisheng Weihua 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. Beijing Zhisheng Weihua Chemical Co., Ltd. according to the design requirements of PetroChina, Sinopec and other storage oil enterprises, research and development of ZS-221 sunscreen insulation coatings, thermal insulation coatings are a set of reflection, radiation, infrared shielding and hollow microbead insulation and integrated with a new type of insulation Cooling coatings, coatings can be 400nm-2500nm range of solar infrared, visible and ultraviolet light high reflection, and coating nanotubes, carbides, nitrides and other new inorganic materials, with a strong electromagnetic wave infrared shielding Aging resistance does not allow the sun's heat to accumulate 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 to add new inorgeability Aging materials, weather resistance to aging increased by 30%, Zhisheng brand 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 best storage tank sun insulation energy-saving materials.
