Northeast Wood Processing Plant Poplar Board Poplar Tray Material

Description :

　　In the wood production enterprises of Northeast Wood Processing Factory, there is usually a large amount of combustible materials piled up during the wood processing process, including raw materials, semi-finished and finished products, as well as a large amount of sawdust, shavings, dust, etc. Once ignited, the spread speed is fast Log recording

　　The flame spread rate is zero. 35-7 meters per minute; 8-12% moisture content of wood at 4 meters per minute;

　　When the moisture content of sawn timber exceeds 30%, it is 1 meter per minute; The fire hazards of sawdust and wood powder are greater. When the moisture content of sawdust is 5-8%, its ignition point is 210-230 ℃, and its self ignition point is 250-350 ℃. It can be welded to a spark

　　There are also stuffy cigarette butts Sawdust can spontaneously ignite when heated for a long time, with an initial self heating temperature of about 100 ℃ New sawdust containing 30% to 40% water, if piled up, can also spontaneously ignite due to the action of microorganisms.

　　2. Wood chips are explosive and self igniting

　　The wood dust generated during the processing and production of wood can form an explosive mixture with air, such as the moisture in wood powder

　　Below 6.4% and 1.5% ash content, the lower explosive limit is 12.6-25g/m3, the explosive pressure is 0.77MPa, the small ignition energy is 20NJ, and the self ignition point of deposited dust is 225 ℃.

　　In the production, screening, grinding, sawing, sanding, and other processes of wood, chips, and fiberboard, a large amount of sawdust and sawdust are easily ignited and often generate heat due to sparks, friction, and mixed mechanical impacts on raw materials

　　Hard impurities such as sand and gravel collide with mechanical equipment to create a spark that ignites sawdust or wood dust.
