Roofing sandwich panels
Product Description
● Heat insulation and cooling
(1) The magnesite panel is 20 cm above the surface of the warehouse, forming an effective space, ensuring the smooth flow of air in the compartment, and greatly reducing the temperature of the warehouse. Nearly effectively reduce the influence of the outside on the temperature in the warehouse and the temperature of the grain pile. It can delay the aging of grain quality, extend the storage life, reduce the number of smoked warehouses and ventilation cooling, extend the replacement life of the roof waterproof layer, avoid the maintenance of the roof waterproof layer, and increase the comprehensive benefits.
(2) Isolate 70%-80% of the heat absorbed from the roof of the warehouse, effectively reducing the indoor temperature. The thermal conductivity of roof composite panels is 0.0141w/m.k. The test after use by the customer shows that the temperature in the warehouse is reduced by 6-12 °C in the high temperature season; The average grain temperature in the warehouse can be controlled below 20 °C, and the highest surface grain temperature can be controlled below 25 °C.
●The product has a certain waterproof function, and the original SBS waterproof layer on the top of the warehouse is protected from wind and sun, delaying aging and enhancing service life.
●Effectively inhibit the occurrence and development of mold, greatly weaken the activity of grain storage pests, basically stop reproduction, and effectively prevent the harm of insect mold.
●Due to the avoidance or reduction of the use of chemical drugs to kill insects, it not only reduces the workload of food preservation personnel, but also protects the health of staff; Avoid or reduce pollution to food and ecological environment.
● It can reduce the respiration volume of paper food by 80%-90%, so that the food organism is in an extremely weak metabolic process. Effectively inhibit the aging of water grain quality and prolong the storage period.
●It can store food with relatively high moisture.
● Save storage costs.
It has been proved that magnesite thermal insulation and ventilation products fully meet and realize the requirements of low temperature grain storage.
Second, fire and sound insulation, moisture-proof and water-resistant, strong frost resistance
The magnesite surface board of the roof composite panel does not burn at 800 °C, and the non-combustibility reaches GB8624A; Water absorption≤ 18%; 50 cycles of freeze-thaw without damage.
Third, high strength, impact resistance
Flexural strength (Mpa) of veneer on the surface of roof composite panels≥16; Impact strength (KJM2) ≥ 3.6.
Fourth, light weight, small roof load
Use this product to increase the roof load by about 20kg/m2. The product is mass-produced and installed as a whole.
5. Green environmental protection, non-toxic and tasteless
No toxic and harmful substances, no radiation.
