Evaluation of the Surface Irregularities of the Cross-Section of the Wood after CO Laser Cutting.

The present paper deals with the analysis of cross-section surface irregularities after CO laser cutting. The surface irregularities of beech ( L.), oak (), and spruce ( L.

Effect of Low-Thermal Treatment on the Particle Size Distribution in Wood Dust after Milling.

The thermal treatment of wood can improve the appearance of the wood product's surface, its dimensional stability, and resistance to fungal attacks. However, the heat treatment changes the technological properties of wood, making it a new engineering material. This work investigates the effect of the low-thermal treatment of birch wood ( Roth.

The Dust Separation Efficiency of Filter Bags Used in the Wood-Based Panels Furniture Factory.

The relationship between the conditions of the use of filter bags made of non-woven fabric and the separation efficiency of wood dust generated in a furniture factory was experimentally determined in the conditions of pulse-jet filtration using a pilot-scale baghouse as waste during the processing of wood composites. The experiments were carried out, and we describe the results of the experiment as consisting in assembling one type of filter bag in two dust extraction installations operating under different operating conditions in the same furniture factory. The filter bags working in the assumed time intervals were then tested for their separation efficiency using a stand for testing filtration processes on a pilot scale.

Occupational Exposure to Dust Produced when Milling Thermally Modified Wood.

During production, thermally modified wood is processed using the same machining operations as unmodified wood. Machining wood is always accompanied with the creation of dust particles. The smaller they become, the more hazardous they are.
