China has bought more than 160 million tons of autumn grain so far, according to the National Food and Strategic Reserves Administration. Since the 18th National Congress of the Communist Party of China, China's grain production has achieved successive harvests, with grain output stable at more than 650 billion kg for eight consecutive years, and per capita grain consumption reaching 483 kg, higher than the internationally recognized food security line of 400 kg.

  We will work hard to ensure stable production and supply of grain and major agricultural products

  Is one of the core themes of this year's central document No. 1

  It is also the top priority of accelerating the construction of an agricultural powerGrain collection and storage is an important material basis for ensuring national food security, and there are thousands of central reserve grain depots throughout the country.

What are the risks of grain reserves?

  At present, the main types of granaries in China are tall bungalow, shallow round silos and vertical silos, which are greatly affected by solar radiation and air humidity. In particular, once the temperature rises to a certain extent, the respiration of grain will be significantly strengthened, and heat and water vapor will be distributed inside the granary, which is easy to cause grain moldy deterioration; Too high a temperature can even cause combustion, and the consequences are even more dire.

What are the advantages of low temperature grain storage?

  Low temperature storage is a kind of modern grain storage technology, mainly through electronic temperature measurement, mechanical ventilation, internal circulation temperature control technology to keep the grain pile in a certain low temperature state, improve the stability of grain storage. To achieve low temperature grain storage, it is necessary to complete the design and modification of the warehouse envelope, including the insulation layer and moisture-proof layer, but if the physical transformation is carried out in a large area, the investment is large, the benefit is small, and it is not suitable for large-scale promotion.

The exclusive protective film of granary - heat insulation and flame retardant coating

  Since the transformation of the warehouse envelope is not the most preferred item, it is better to change the idea - to cover the granary with a layer of exclusive protective film. The new reflective heat insulation energy-saving flame retardant multi-functional polymer nano coating of Titanium technology, heat insulation and flame retardant performance have reached the national advanced level, and can shoulder the heavy responsibility of protecting grain silos:

1. Heat reflex: Keep the grain silo "calm"

  The coating can not only reflect 400nm-2500nm red/ultraviolet light, but also promote the thermal radiation on the surface of the object, so as to effectively reduce the heat accumulation on the top of the granary, so that the temperature in the warehouse is reduced by about 35%, and maintain the stable state of low temperature in the warehouse;

2. Modified flame retardant factor: prevent granary "roof fire"

  Through structural adjustment and filler modification, the coating can form a tight coating on the surface of the material, isolate the contact between the material and oxygen, and at the same time trap free radicals involved in the combustion reaction, inhibit the chain reaction, prevent flame propagation, and avoid combustion

  The new reflective heat insulation, energy saving and flame retardant multi-functional polymer nano coating of Tiantian Technology adds a special protective film to the grain warehouse, realizing safe and efficient grain storage and helping to ensure national food security.
