Embodiment
[0034] Example: such as Figure 1-5 As shown, the present invention provides a kind of technical scheme, a kind of wood flame retardant treatment method, comprises the following steps:
[0035] ① Put the wood 9 into a sealed treatment tank, use a vacuum pump to evacuate, and keep it for a certain period of time, so that the air in the wood cell cavity is drawn out;
[0036] ②While step ① is carried out, irradiate the wood 9 with microwaves to promote the vaporization of the wood 9 cell liquid, and the vaporized wood 9 cell liquid is drawn out under the air pressure difference;
[0037] ③Inject flame retardant into the treatment tank, and maintain the negative pressure state in the treatment tank during the process;
[0038] ④ After the flame retardant is filled with the treatment tank, increase the contact pressure between the flame retardant and the surface of the wood 9 to impel the flame retardant to immerse into the inside of the wood 9;
[0039] ⑤ After step ④ is comple...

The invention discloses a wood flame-retardant treatment method which comprises the following steps: (1) putting wood into a sealed treatment tank, vacuumizing by using a vacuum pump, and keeping for a certain time, so that air in cell cavities of the wood is pumped out; (2) irradiating the wood with microwaves while the step (1) is carried out, vaporizing cell sap of the wood, and extracting the vaporized cell sap of the wood under the air pressure difference; (3) a flame retardant is injected into the treatment tank, and the negative pressure state in the treatment tank is kept in the process; (4) after the treatment tank is filled with the flame retardant, increasing the contact pressure between the flame retardant and the surface of the wood to promote the flame retardant to immerse into the wood; (5) evacuating the flame retardant after the step (4) is completed, and injecting air to maintain pressure; according to the treatment method, the equipment structure is simplified, the manufacturing and maintenance cost is reduced, moisture in cell walls of the wood is more easily removed, the action depth is large, the wood is dewatered and degassed more rapidly and thoroughly through the synergistic effect with vacuumizing, and the follow-up soaking effect of the flame retardant is better, and the soaking degree of the flame retardant is higher.
Description
technical field [0001] The invention relates to the technical field of wood processing, in particular to a fire-retardant treatment method for wood. Background technique [0002] A method of improving the fire resistance of wood by physical or chemical methods. The purpose is to slow down the burning of wood to prevent the occurrence of fire, or buy time to quickly eliminate the fire that has occurred. Wood has a high hydrocarbon content and is a flammable material. So far there is no way to keep wood from burning when it is near a fire. The requirement for wood flame retardancy is to reduce the wood burning rate. Reduce or retard the speed of flame propagation and accelerate the carbonization process of the burning surface. This is of paramount importance for industrial sectors such as construction, shipbuilding, and vehicle manufacturing. Contents of the invention [0003] The invention provides a wood flame-retardant treatment method, which not only simplifies the ...
