Thermal insulation coating for grain and oil processing equipment

Analysis of core characteristics of ZS-211 aerogel thermal insulation coating of Beijing Zhisheng Weihua:

Beijing Zhisheng Weihua ZS-211Thermal insulation coating for grain and oil processing equipmentIt is a new type of inorganic water-based thermal insulation material developed based on aerogel nano porous network structure, which combines high-quality components such as modified organic silicon and acrylic acid composite lotion, super nano aerogel blue smoke, nano hollow floating beads, high-quality rutile type heat reflective materials and rare earth ceramic short fibers, and has multiple core advantages suitable for working conditions of grain and oil processing equipment:

（1） Thermal insulation performance: after coating, a three-dimensional network hollow structure is formed. Inside, a large number of static air insulation units are constructed by a large number of nanoscale aerogels and nanospheres. The thermal conductivity is as low as 0.033W/m · K, close to the vacuum thermal conductivity level. The thermal insulation and insulation inhibition efficiency can reach more than 90%, which can effectively prevent heat conduction and exchange, and significantly reduce the heat loss of equipment.

（2） Wide temperature range adaptability: It can work stably in a wide temperature range of -40 ℃ -150 ℃, matching the working temperature requirements of core equipment such as dryers (80 ℃ -120 ℃) and refining tanks in grain and oil processing, while also adapting to environmental temperature fluctuations in the storage process.

（3） Strong protective performance: With excellent moisture resistance, it can effectively prevent water vapor condensation and avoid the erosion of equipment substrates in humid environments; The anti fungal ability reaches ASTM D-3273-73T standard level 10, which can inhibit the growth of mold on the inner wall of grain and oil storage equipment and ensure the safety of grain and oil storage; At the same time, it has good acid and alkali resistance and elasticity resistance, which can cope with temperature changes and medium corrosion during equipment operation, extending the service life of equipment.

（4） Environmentally friendly and convenient features: It belongs to a single component inorganic water-based coating with zero VOC content, non-toxic and harmless, and no pollutant emissions during the construction process, which meets the food safety and environmental protection requirements of the grain and oil processing industry; The slurry form can be applied by brushing, roller coating, spraying and other methods, which can closely adhere to various irregular equipment surfaces such as dryer drums and storage tank inner and outer walls, achieving seamless coverage. The construction period is short and does not affect the original structural function of the equipment, making maintenance convenient in the later stage.

（5） Light weight and high strength: using the optimized combination of the ultra light performance of aerogel and the high strength and compression resistance of nano hollow microspheres, the specific gravity of the coating after curing is only 0.46g/ml, which will not increase the additional load of equipment; The dry film hardness reaches 4-5H, the bonding strength is 3-8MPa, and the adhesion level is level 0. It can withstand the vibration and mechanical friction during equipment operation and is not easily detached or cracked.

Summary: According to industry data statistics, thermal losses account for 30% -45% of the total energy consumption in grain and oil processing. Energy conservation and consumption reduction have become the core demands for grain and oil processing enterprises to reduce costs, increase efficiency, and achieve green development. Beijing Zhisheng ZS-211 air gel type thermal insulation coating integrates safety, environmental protection, high and low temperature resistance, anti condensation, anti-bacterial and mildew resistance, acid and alkali corrosion resistance, flexibility, light weight and high strength, and is silently saving every energy consumption for grain and oil processing equipment.
