Embodiment 1

[0009] Embodiment 1: refer to figure 1 , the treatment method for the color difference of wood stacking is to pile up the stacks sequentially in the order of a layer of sawn wood 3 and a layer of sawdust or wood shavings 2 of the same species as wood 3 on the flat ground or on the bracket 1, and stack them on the top A frame 4 is placed on the wood layer 3, and the top layer of sawdust or shavings 2 of the same tree species as the wood is placed in the frame 4, and one layer of wood 3 and another layer of wood 3 are placed horizontally and vertically in the shape of a well The flat seams and vertical seams between each layer of wood and between layers are 10-15mm, and the thickness ratio of each layer of wood to sawdust or shavings of the same species of wood is 10:4-5. The thickness of the top layer of sawdust or shavings of the same species as the wood is 100-150mm. Sprinkle water from the upper layer to the lower layer, once every 4 to 6 hours, until the whole pile is dren...

Embodiment 2

[0010] Embodiment 2: the processing method of container water immersion wood color difference, by 1M 3 Wood and sawdust or wood shavings of the same tree species are 20-30kg. Put the two in the container, press it with a board frame and a heavy object, and add an appropriate amount of water to the container to soak the two in water. Under the water temperature of the container, the wood and the sawdust or shavings of the same tree species as the wood are desizing for 48-72 hours, and the pigment is precipitated, so that the color difference of the wood is evenly replaced, and then the wood is placed in a drying kiln at 70-100 ℃ At the kiln temperature, the wood is fixed and dried for 200 to 260 hours, and the wood is the finished product after leaving the kiln. The container can be a metal container, or a container made of cement. To make the water temperature in the container reach 60-90°C, a fire channel for heating the container is set under the container. The wood treate...

Abstract

The timber color difference treating method includes: first stacking timber and sawdust of the dame kind of timber inside some frame alternately and showering with water in normal temperature once every 4-6 hr for 90-140 hr to desize, separate pigment and homogenize in color, or soaking timber and sawdust of the dame kind of timber in the ratio of 1 cu m to 20-30 kg inside some container with water at 60-90 deg.c under pressure for 48-72 hr to desize, separate pigment and homogenize in color; and then stoving inside a drying kiln at 70-100 deg.c for 200-260 hr to dry and fix the color. The said treating method is simple, pollution-free and low in cost, and the treated timber has natural and homogeneous color.

Description

technical field [0001] The invention is a treatment method for wood color difference. Background technique [0002] After the wood is processed into boards and squares, there will be different degrees of color difference, which is the natural property of the wood itself. The existence of wood color difference seriously affects the quality and price of wood, and also brings great difficulties to the deep processing of wood. In the prior art, one is to adopt chemical treatment methods such as ammonia water and hydrogen peroxide. The disadvantage of this chemical treatment method is that the treatment cost is high, and it pollutes the environment. It usually makes the treated wood turn white and deteriorate, and lacks the natural color feeling of the wood; A method of degrading plastic-wrapped wood treatment. The disadvantage of this treatment method is that it is labor-intensive and time-consuming, and the treatment cost is high. Usually, the tone of t...
