Since January 2011, the temperature in Jilin Province is extremely low, and there is very little snowfall. The Jilin Provincial Meteorological Observatory predicts that from January 31, the temperature will rise significantly from west to east. From January 31 to February 5, the average temperature in the province was minus 7 to 9 degrees Celsius, which was 5 to 7 degrees Celsius lower than the annual average of 14.6 degrees Celsius. The extreme minimum temperature is generally 10 to 14 degrees Celsius in most parts of the province, and the north and southeast mountain areas can reach minus 20 to 23 degrees Celsius. The extreme maximum temperature is generally minus 3 to 5 degrees Celsius in most parts of the province. The place can reach above 0 degrees Celsius.
It is estimated that there is still no obvious snowfall in Jilin Province here. There is uneven snow distribution in the central and southern parts of the country around the 4th. The average snowfall in the province is less than 0.4 mm, which is less than 0.8 mm in the same period of the previous year.
The temperature rise is beneficial to the agricultural production of facilities. It is recommended that all localities strengthen the management of agricultural production in facilities on the eve of the Spring Festival to improve production efficiency. At the same time, it is reminded that relevant enterprises and farmers still need to apply cold-proof measures to the greenhouse at night to prevent freezing damage. At the same time, the temperature rise is good for grain threshing and sales, and it is recommended that farmers everywhere pay close attention to grain threshing and grain sales.
Ceramic Fiber Board is a lightweight refractory material processed with alumina-silica fibers for applications at temperatures up to 1400℃.
Ceramic fiber board is a vacuum formed product that resists higher gas velocities than Ceramic Fiber Blanket.
It is ideal for furnace, boiler duct and stack lining due to its low thermal conductivity and low heat storage allowing shorter cycle times and quicker access for maintenance.
Features
Low thermal conductivity
Low heat storage
Light weight
Excellent thermal shock resistance
Resistant to hot gas erosion
Resists most chemical attacks
Easy to cut, handle and install
Low sound transmission
Resists penetration by molten aluminum and other non-ferrous metals
Asbestos free
Typical Applications
Refractory lining for industrial furnaces in walls, roofs, doors, stacks, etc.
Combustion chamber liners, boilers and heaters
Back-up insulation for brick and monolithic refractory
Transfer of molten aluminum and other non-ferrous metals
Expansion joint boards
Barrier against flame or heat
Hot face layer for high velocity or abrasive furnace atmosphere
