The invention discloses a fine picking and utilization equipment for wood that is not up to standard in building monitoring. Internally, the top of the right end of the body is vertically connected to the bottom of the alarm indicator, the back of the control panel is fixedly connected to the front of the top of the body, the front cover is installed on the front of the body, and the cooling vents are arranged in the same order from top to bottom. The feet are connected to a rectangular structure and arranged at the bottom of the body. The device can perform layered cutting of the cracked wood material in the building monitoring. The first cutting disc, the middle cutting disc and the second cutting disc can simultaneously cut the square material into thickness. The same wooden boards, and then pick out the non-cracked boards to assemble into new objects, and the remaining unqualified ones are broken, which can minimize the loss of wood.

The invention provides a high-speed spiral corn-shaped milling cutter for wood and belongs to the technical field of wood machining. The milling cutter is in the shape of a corn and composed of a cutter body, cutters and an end cover counter weight, wherein the diameter phi of the cutters ranges from 160mm to 240mm, the rotating speed is 1000rpm-10000rpm, 2-6 rows of spiral grooves are evenly distributed on the cutter body, the width of the grooves ranges from 30mm to 70mm, the spiral included angles of adjacent grooves range from 5 degrees to 15 degrees, the adjacent spiral grooves are axially distributed in staggered mode, 6-10 cutters which are of a combined structure are evenly distributed on each row of groove, the front angle of a blade ranges from 20 degrees to 26 degrees, and the rear angle of the blade ranges from 9 degrees to 13 degrees, and a disc-shaped spring is installed under the cutters, so that compensation on abrasion of the cutters can be achieved. 2-4 groups of counter weight draw bars are installed on the counter weight end cover, 2mm-4mm of circumferential position adjusting on the counter weight draw bars can be achieved, and the requirement on movable balance of high-speed rotation of the corn-shaped milling cutter can be met. The high-speed spiral corn-shaped milling cutter can achieve high-speed cutting in the fine-machining process of wood, and has the advantages of being low in noise, power consumption and dust and high in quality.

The invention belongs to the field of preparation of composite performance materials, and provides a preparation method of high-density anisotropic conductive metalized wood, which comprises the following steps: pretreating a wood fiber structure; carrying out vacuum infiltration on metal liquid in a wood fiber channel; and carrying out surface treatment on the metalized wood. In the pretreatmentstep, lignin in a log fiber structure is washed away without destroying the fiber structure by adopting a mixed solvent of dilute ammonia water and an alkali metal halide aqueous solution, a good fiber channel is provided for permeation of molten metal, and meanwhile, nano halide molten salt particles precipitated from the wood fiber structure can achieve a flame retardant effect at a high temperature; the permeated metal is an alloy material, the metal is melt into a liquid state in a constant-temperature vacuum oven, then wood to be permeated is soaked into the molten metal, and permeation is carried out under a vacuum condition; and after the permeation is completed, the surface of the metalized wood finishing the permeation is polished through mechanical polishing equipment, and thus the large-density anisotropic metalized wood with a uniform surface and a good state is obtained.

The present invention relates to a water-borne UV-curable coating composition for use in wood finishing of interior joinery, furniture, and in particular in kitchen industry.
