Storage tanks are containers used to store liquids or gases, and are essential and important infrastructure in industries such as petrochemical, grain, oil, food, metallurgy, and national defense. For many enterprises, storage tanks are indispensable for normal production, especially for national Strategic material reserve.

The strength of the service life of storage tanks has a certain impact on production costs and benefits. In daily use, it is crucial to do a good job in thermal insulation.

Current status of metal storage tank insulation

Taking oil storage tanks as an example, the existing external wall insulation of oil storage tanks generally uses angle steel and flat steel to make a fixed structure of insulation layer, uses steel strips and other fixed insulation materials, and finally installs a metal protective layer. Insulation materials are mostly rock wool, mineral wool, and silicate materials. In long-term use, the insulation structure has the following problems:

1. Under the external force of wind, some protective layers may fall off or have warped edges and cracks due to improper construction, resulting in water ingress into the insulation layer.

2. Traditional insulation materials belong to porous structures, which are prone to water absorption and failure, resulting in a decrease in insulation effect and short service life.

3. Due to water ingress into the insulation layer, a water vapor sealing system is formed under the protective layer, which accelerates the occurrence of corrosion under the insulation layer, especially at the locations where thermocouples, thermometers, safety valves, and other accessories are installed on the pipe wall, which is prone to corrosion.

4. Due to the limitations of traditional insulation materials, the top of the tank is generally not insulated, resulting in serious heat dissipation issues. Especially for floating roof tanks, in actual production, the tank is not fully filled, resulting in an increase in the proportion of heat dissipation area occupied by the tank top.

In view of the above problems, Aerogel thermal insulation coating is recommended for thermal insulation.

Aerogel thermal insulation coating is a new high-performance Aerogel thermal insulation coating prepared by special process with special high-performance resin lotion, preferred silica Aerogel and hollow glass beads as thermal insulation materials and water as solvent. The temperature resistance range is -40~120 ℃, which is suitable for medium and low temperature conditions.

Aerogel thermal insulation coating can be used for the thermal insulation of light oil tank bodies such as gasoline and diesel oil in petrochemical production enterprises, and for the tank bodies of various light hydrocarbon spherical tanks such as liquefied gas, propylene and propane that need to be cooled by spraying in summer, which can effectively reduce the heat exchange inside and outside the tank, and effectively block the transmission of solar radiation heat and heat radiation in the air, The 2mm Aerogel thermal insulation coating system can reduce the internal temperature of the tank by more than 10 ℃, and reduce the spray frequency in high summer temperature, so as to avoid premature failure of the tank body due to continuous spray.

Excellent insulation performance

Aerogel thermal insulation intermediate coating is a thermal insulation unit, which can effectively reduce heat transmission and has excellent thermal insulation effect. The insulation effect of 2mm AG-C Aerogel thermal insulation coating system is 50% higher than that of ordinary reflective thermal insulation coating, and 5-10 ℃ lower than that of 70mm thick rock wool+aluminum skin.

Hydrophobicity

The hydrophobicity of Aerogel reaches 99%, and the coating surface is free of water and dirt, which can prevent corrosion under the insulation layer.

Lightweight and crack resistant

The Aerogel thermal insulation coating is light, thin and crack resistant, which can avoid the falling off problem caused by too thick insulation layer.

Excellent flame retardant performance

Aerogel thermal insulation coating has good flame retardancy, and will not cause burning and combustion supporting phenomenon.

Good airtightness

Forming a dense elastic membrane material, safe and environmentally friendly, free from toxic and harmful substances.

Easy construction

Only 3~4 construction procedures are required, which is simple and convenient, greatly shortens the construction period, and correspondingly improves the construction Factor of safety.

Long service life

The service life of Aerogel thermal insulation coating is more than 10 years, which can greatly reduce the difficulty of inorganic waste treatment caused by frequent maintenance.

Safe and non-toxic

Water based formula, free of volatile harmful compounds, safe and non-toxic.

In addition, the same series of products of Zhongning Technology also have Aerogel high temperature coating suitable for high temperature conditions, which is mainly used for anti scalding of industrial high temperature pipelines and equipment surfaces (ethylene cracking furnace, heating furnace, coal mill, dryer, etc.), and is suitable for thermal insulation on abnormal parts such as valves, flanges, and abnormal equipment that are not often disassembled, as well as caulking or adhesives in the high temperature field, to solve the "last mile" of thermal insulation. For example:

Equipment, pipelines, and their accessories that do not require insulation in process production, and whose external surface temperature exceeds 60 ℃ and require frequent operation and maintenance. When other measures cannot be taken to prevent scalding, anti scalding insulation is required.

The range of anti scalding and thermal insulation settings is: the height from the ground or working platform is less than 2.1m; The distance near the operating platform is less than 0.75m.
