Embodiment 1

[0042] A method of locking moisture in wood comprising the steps of:

[0043] Step 1: Under vacuum, control the gas content and moisture content of the wood that needs to lock in moisture; the moisture content is controlled at 8%, and the gas content is controlled at 0.01%;

[0044] The second step: under vacuum, put the paraffin into the container, and heat it to melt it completely; the vacuum is 0.01MPa; the straight-chain alkanes in the paraffin account for 80%; Cyclocycloalkane accounts for 2%; melting temperature is 55°C;

[0045] The third step: Put the wood obtained in the first step into the container of the second step, completely immerse the wood in the melted paraffin, keep it for 20 minutes, and keep the container in a vacuum state; the vacuum degree is 0.01MPa;

[0046] Step 4: Under vacuum, lower the temperature in the container to normal temperature, so that the molten paraffin solidifies and seals the internal gap of the wood; the vacuum degree is 0.01MPa;

Embodiment 2

[0050] A method of locking moisture in wood comprising the steps of:

[0051] Step 1: Under vacuum, control the gas content and moisture content of the wood that needs to lock in moisture; the moisture content is controlled at 12%, and the gas content is controlled at 0.02%;

[0052] The second step: under vacuum, put the paraffin into the container, and heat it to melt it completely; the vacuum is 0.05MPa; the straight-chain alkanes in the paraffin account for 90%; Cyclocycloalkane accounts for 3%; melting temperature is 75°C;

[0053] The third step: put the wood obtained in the first step into the container of the second step, completely immerse the wood in the melted paraffin, keep it for 50 minutes, and keep the container in a vacuum state; the vacuum degree is 0.05MPa;

[0054] Step 4: Under vacuum, reduce the temperature in the container to normal temperature, so that the molten paraffin solidifies and seals the internal gap of the wood; the vacuum degree is 0.05MPa; ...

Embodiment 3

[0059] A method of locking moisture in wood comprising the steps of:

[0060] Step 1: Under vacuum, control the gas content and moisture content of the wood that needs to lock moisture; the moisture content is controlled at 16%, and the gas content is controlled at 0.05%;

[0061] The second step: under vacuum, put the paraffin into the container, and heat it to melt completely; the vacuum is 0.1MPa; the straight chain alkanes in the paraffin account for 95%; Cyclocycloalkane accounts for 4%; melting temperature is 80°C;

[0062] The third step: put the wood obtained in the first step into the container of the second step, completely immerse the wood in the melted paraffin, keep it for 2 hours, and keep the container in a vacuum state; the vacuum degree is 0.1MPa;

[0063] Step 4: Under vacuum, reduce the temperature in the container to normal temperature, so that the molten paraffin solidifies and seals the internal gap of the wood; the vacuum degree is 0.1MPa;

Abstract

The invention provides a method for locking water in wood and wood processed with same. The method comprises the following steps of: under a vacuum condition, controlling a gas content and a water content in wood in which water needing to be locked; under the vacuum condition, putting paraffin in a container and heating to fully melt the paraffin; putting the wood obtained in the first step in the container of the second step, fully immersing the wood in the melted paraffin, keeping a certain time and keeping the container in a vacuum state; under the vacuum condition, lowering temperature in the container to a normal temperature, solidifying the melted paraffin and blocking gaps in the wood; and taking out the wood, and removing the paraffin attached to the surface. The problem that the wood shrinks when dry and expands when wet is thoroughly solved, and the emission of smell in the wood is avoided. The method can be used for wood engineering and furniture industry and is environment-friendly and energy-saving. The wood cannot crack or deform and has good mothproof and corrosion-proof effect. The method can particularly produce great economic benefit for the production, transport and use of red wood furniture.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a method for locking moisture in wood by using hot wax technology and wood treated by the method. Lock the moisture in the wood, that is to maintain a certain ratio of moisture and gas in the wood. Background technique [0002] In the prior art, most of the raw materials of wooden products and wood decoration projects adopt drying treatment or anti-corrosion treatment. Such as soil method drying, steam drying, vacuum drying, microwave drying, chemical antiseptic, drug antiseptic, etc., these methods are mainly to remove moisture in wood. [0003] Because there are a lot of voids inside the wood, it can absorb the gas and moisture in the air with the change of the external environment, of course, the gas and moisture will be released through the voids, and the shrinkage and expansion of the wood will cause the wood to crack and deform. ; On the other hand, the smel...
