Abstract

The invention discloses a eucalyptus wood board processing technique. The eucalyptus wood board processing technique comprises the steps that (1) eucalyptus wood boards are kept drying for 30-40 s at the temperature of 75-85 DEG C and under the pressure of 0.25-0.30 MPa, wherein a layer of quartz sand with the thickness being 0.05-0.1 mm is laid on a bottom layer where eucalyptus wood is placed firstly and used as a quartz sand layer, the eucalyptus wood boards are laid on the quartz sand layer, gauze is placed on the eucalyptus wood boards, and sawdust gauze with the thickness being 0.2-0.5 mm and sawdust are placed on the gauze, so that the eucalyptus wood boards are separated; and (2) dewatering is conducted, the total drying time in the whole dewatering process is 125 min, and the drying temperature is 55-65 DEG C. The eucalyptus wood boards obtained through the processing technique are free of cracks, good in tenacity and free of pulverization; the quartz sand and the sawdust are placed in the eucalyptus wood board drying process so that the drying water loss rate can be effectively increased, and the dried eucalyptus wood boards are better in quality and tenacity; and furthermore, the eucalyptus wood board processing technique is low in time consumption, energy consumption and cost.

Description

technical field [0001] The invention relates to the technical field of wood processing, in particular to a process for processing eucalyptus boards. Background technique [0002] Eucalyptus is a light-colored hardwood with a tight and irregular grain. The sapwood layer is relatively wide and white to pale pink; the heartwood is light brownish red. Eucalyptus is a kind of fast-growing wood, which is not tough, light in weight, and easy to break. You should choose other tough, smooth, and heavy miscellaneous materials. Eucalyptus wood grows widely in southern China and is used in many ways in the production of cabinets and furniture, especially for antique furniture. Eucalyptus wood is generally cut and placed for a period of time, waiting for the eucalyptus wood to dry to a certain extent, and then subsequent processing. This kind of placed wood is mostly placed in the sun and directly exposed to the sun. The consequences of this treatment lead to the problem of cracking a...
