Safety common sense of wood processing plant

Safety common sense of wood processing plant

1. More combustibles, spontaneous combustion and combustibility

In good circulation, sawdust and sawdust tend to turn from smoldering to flame burning, thereby igniting dry wood. Steam drying is easy to control and safe. But the drying temperature is high, such as the drying temperature of the plywood production is 180. If the temperature and time are not properly controlled, the system can not be cleaned strictly.

2. hot pressing process

Plywood and fiberboard are produced by hot pressing process, and plywood and fiber are bonded together by hot pressing. The burning point of the fiberboard is 190 ℃, and the exothermic reaction intensifies when the temperature is above 160 degrees centigrade, and the hot pressing temperature is between 160--200 , if the control is improper, the dust is prone to fire. After hot pressing, the temperature of plywood and fiberboard is relatively high. If heat treatment is not carried out, sudden thermal self ignition will occur easily.

3. gelatin, spray, glue and glue preparation process

The glue used for gluing glue and wood parts is urea formaldehyde resin, phenolic resin, leather glue and bone glue. The fire risk of urea formaldehyde resin is more dangerous; when preparing phenolic resin and urea formaldehyde resin, flammable liquid should be used as diluent. If electric spark or open fire is an easy cause of fire, it is very easy to cause fire. When making rubber compound, burn the glue and bone glue with the stove, and if the fire is not properly controlled, it may cause a fire.

4. painting and painting process

In the process of painting, the products need to use paint, nitro lacquer and various solvents, dry oil and so on. Most of these items are flammable and combustible liquids, especially the spray nitro lacquer will produce solvent steam, and the mixture of air can form an explosive mixture. When painting, it will generate and accumulate static electricity. When discharging, it will cause solvent vapor to burn and ignite other combustible materials.
