Embodiment Construction

[0008] The present invention will be described in further detail below: the present embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation is provided, but the protection scope of the present invention is not limited to the following examples.

[0009] A medium-high-density board added with bamboo charcoal involved in this embodiment includes: a density board and bamboo charcoal powder, and the amount of the bamboo charcoal powder is one-tenth to one-thousandth of the weight of the density board.

[0010] The consumption of described bamboo charcoal powder is 1% of density board weight.

[0011] The consumption of described bamboo charcoal powder is 5 / 1000 of density board weight.

[0012] A method of adding bamboo charcoal to medium and high-density boards. A hole is opened on the pipe wall of the secondary air supply of the large cyclone, and the outlet of the screw conveyor is connected with the hole on the p...

Abstract

The invention provides middle-high density plywood with added bamboo charcoal and a method for adding the bamboo charcoal thereof, and belongs to the technical field of density plywood and the method of adding the bamboo charcoal thereof. According to the middle-high density plywood with added the bamboo charcoal, the dosage of bamboo charcoal powder is one tenth to one thousandth of the weight of the density plywood. A hole is formed in a pipeline wall carrying out secondary air supply by large cyclone, the outlet of a spiral conveyer is communicated with the hole in the pipeline wall carrying out the secondary air supply by the large cyclone, the inlet of the spiral conveyer is communicated with a stock bin of the bamboo charcoal powder, the bamboo charcoal powder and wood fibers are sent to a spreading machine through the secondary air supply and are evenly paved on a preforming press, and then hot press molding is carried out. The surface of the middle-high density plywood presents tiny black dots after the bamboo charcoal is added, and physical experiments carried out on the middle-high density plywood shows the facts that the combination intensity of the inner portion of the density plywood is not influenced, the surficial combination intensity of the density plywood is not influenced either, and the veneer attaching of any material on the density plywood added with the bamboo charcoal is not influenced. The middle-high density plywood with added bamboo charcoal and the method for adding the bamboo charcoal thereof meet the technical standard of domestic middle-high density fiberboards.

Description

technical field [0001] The invention relates to a medium-high density board added with bamboo charcoal and a method for adding bamboo charcoal, and belongs to the technical field of density board and the method for adding bamboo charcoal. Background technique [0002] Density board, also known as fiberboard. It is an artificial board made of wood fiber or other plant fiber with urea-formaldehyde resin or other suitable adhesives. According to its density, it can be divided into high-density board, medium-density board and low-density board. Medium-density fiberboard is made by processing selected wood raw materials into fibers, and then applying urea-formaldehyde resin and other additives to make it with a density of about 0.5-0.88g / cm 3 A kind of man-made board. The technical standard parameters of domestic first-class MDF are as follows: 1. The thickness deviation of the board should be small, and generally should be controlled within ±0.3mm. 2. Water absorption thickne...
