The present invention relates to a vacuum pressure impregnation method for quality materials and an apparatus used therefor.

こと等も行われている。BACKGROUND ART Easily flammable porous materials such as wood and cardboard are impregnated with flame retardants to impart flame retardancy and are widely used as building materials and furniture materials. Furthermore, in order to give castings and ceramic products a certain level of strength, reinforcing agents are impregnated into them.

の第２液とを反応させ反応層を形成させる。Conventionally, one-component treatment liquids have been commonly used for such impregnation treatments, but recently, two types of chemical solutions have been impregnated into the treated object in sequence, and both liquids are mixed inside the treated object. A two-component reaction type (for example, a flame retardant made of a combination of a barium chloride solution and a diammonium hydrogen phosphate solution, a reinforcing agent made of a two-component curing emulsion, etc.) is used. As a method for impregnating wood or the like with such a two-component reaction type treatment liquid, the following method is generally used, for example. That is, as shown in FIG. 5, first, the wood 2 is immersed in the first treatment tank 1 containing the first liquid for a predetermined period of time to be impregnated with the first liquid. Next, the wood 2 is pulled up from the treatment tank 1 and running water is applied to wash away the first liquid remaining on the wood 2. Then, the wood 2 is immersed in the second treatment tank 3 containing the second liquid for a predetermined period of time to impregnate the second liquid, and the inside of the layer of the wood 2 is mixed with the pre-impregnated first liquid. A reaction layer is formed by reacting with the second liquid.
そこで、木材２を処理槽３から引き上げて乾燥すること
により、難燃処理等が施された木材を得ることができる

以上）への難燃処理等が望まれていた。In addition, if excess first liquid adheres to the surface of the wood 2, the second liquid will react excessively to this area and the reaction layer will become uneven. It required careful cleaning, and production efficiency was extremely low. Moreover, since the impregnation process was carried out under normal pressure, the penetration of the liquid into the interior was shallow, and it could only be applied to thin plates (1 to 3 m).
Flame retardant treatment for the above) has been desired.

目的とする。The present invention was developed in view of the above circumstances, and when impregnating the inside of porous materials such as wood with a two-component reaction type treatment liquid, the treatment can be carried out in the same treatment tank, and each porous material can be treated in the same treatment tank. The object of the present invention is to provide a method and an apparatus used therein, which can obtain a reaction layer uniformly formed deep down, with a short impregnation treatment time and a short time for removing a residual liquid after impregnation with a first liquid.

Therefore, according to the present invention, the processes of first liquid impregnation → first liquid removal → second liquid impregnation (reaction) can be performed consistently while the porous material is loaded in the same treatment tank, and Since the surplus first liquid on the surface of the porous material can be effectively removed in a short time by jetting high-pressure fluid, a significant improvement in processing efficiency can be achieved. Furthermore, when impregnating with the first liquid and the second liquid, the pressure inside the treatment tank is reduced before impregnation, and the inside of the treatment tank is pressurized after impregnation to allow the treatment liquid to penetrate deep into the inside of the porous material. Even with thick porous materials, a reaction layer can be formed sufficiently up to the core.

場合と同様、８〜１５ｋｇ／ｃｊに設定する。Using the above-mentioned apparatus, it is possible to impregnate a porous material, for example, in a similar manner. That is, first, processing tank 2
The inner tank 21 containing the porous material 5o is loaded into the container 0, and the opening/closing lid is closed to seal it. Next, the vacuum pump 37 connected to the pressure adjustment pipe 32 is activated, the pressure reducing valve 35 is opened, the inside of the processing tank 20 is made into a vacuum of about 1 to 200 Torr, and the vacuum is maintained for a predetermined time, and then the pressure reducing valve 35 is closed and the vacuum pump 37 is stopped, the on-off valve 10 is opened, and a predetermined amount of the first liquid is supplied into the processing tank 20 from the first liquid supply tank 51 via the piping 28 using the differential pressure. Then, the on-off valve 10 is closed, the on-off valve 25 is opened, and the circulation pump 27 is operated to supply the first liquid to the spray nozzle 23 and spray it from the top, bottom, left and right of the inner tank 21. Liquid injection pressure is 1.5~
Set to about 3 kg/cd1. As a result, the inner tank 2
The first liquid is sprayed in the form of a mist toward the surface of the porous material 50 inside the porous material 1 . Then, a part of it is impregnated into the porous material 50, and the rest flows down and is sprayed from the spray nozzle 23 through the circulation pipe 24 again from the bottom. By repeating this for a predetermined period of time, the first liquid gradually permeates into the porous material 50. After this state is maintained for a predetermined time, the pressure valve 39 connected to the pressure adjustment pipe 32 is opened and the inside of the processing tank 20 is pressurized to a predetermined pressure. This pressurization allows the first liquid that has penetrated into the porous material 50 to penetrate deeper into the interior. Next, the on-off valve 10 is opened and the first liquid remaining in the processing tank 20 is recovered into the first liquid supply tank 51 using the differential pressure. Next, high-pressure air is supplied from the high-pressure air supply pipe 13 and sprayed from the top, bottom, right and left of the inner tank 21 via the spray nozzle 23 . The air ejection pressure at this time is 8 to 15 kg/c
Set to d. By this ejected air, most of the excess first liquid remaining on the surface of the porous material 50 in the inner tank 21 is blown away and falls downward through the mesh of the inner tank 21. Moreover, at this time, the first liquid adhering to the inner circumferential surface of the processing tank 20 and the pipes such as the spray nozzle 23 is also blown away and falls downward. The surplus first liquid that has fallen to the bottom of the processing tank 20 in this manner is collected from the drain pipe 53 and is reused. Then, high-pressure water is introduced from the high-pressure water supply pipe 14 and sprayed from the top, bottom, left and right of the inner tank 21 via the spray nozzle 23. The water injection pressure at this time is 2 to 5 k
Set to g/chill. This jetted water is circulated in the same manner as the first liquid to completely wash away the excess first liquid that could not be removed even by the high-pressure air. At this time too,
The inner peripheral surface of the processing tank 20 and each piping can be cleaned at the same time. Next, high-pressure air is again introduced from the high-pressure air supply pipe 15 and sprayed from the spray nozzle 23 to completely blow away and remove water and the first liquid from the surface of the porous material 50 wetted by the high-pressure water. do. The air injection pressure is set to 8 to 15 kg/cj as in the above case.

From the liquid supply tank 52 via the piping 29 into the processing tank 20,
After a predetermined amount of the second liquid is supplied using the differential pressure, the circulation pump 27 is operated to circulate and spray the second liquid from the spray nozzle 23. The liquid amount and the injection pressure from the spray nozzle 23 are the same as in the case of the first liquid. In this way,
The porous material 50 in the inner tank 21 can be impregnated with the second liquid. As a result, the first liquid previously impregnated inside the porous material 50 and the second liquid react to form a reaction layer inside the porous material 50. After maintaining this second liquid circulation spout for a predetermined time, in the same manner as after impregnation with the first liquid,
The inside of the processing tank 20 is pressurized to allow the second liquid to penetrate further inside. Next, the on-off valve 11 is opened and the second liquid remaining in the processing tank 20 is recovered into the second liquid supply tank 52 using the differential pressure. Then, in the same manner as after impregnating the first liquid, high-pressure air is first injected from the spray nozzle 23 to blow off the excess second liquid, then high-pressure water is injected to clean the surface of the porous material, and high-pressure air is further injected. Spray to completely blow away unreacted residual liquid. Of course, the inner circumferential surface of the processing tank 20 and each pipe are cleaned by this series of injections of high-pressure fluid. Then, by opening the lid and taking out the inner tank 21 and drying it, the desired impregnated product can be obtained.

に芯部まで含浸処理を施すことができた。As described above, according to the above-mentioned impregnation method, since the porous material 50 is impregnated by repeatedly spraying the first liquid and the second liquid, Uniform impregnation treatment can be performed in a short time. In addition, while the porous material 50 is loaded in the same treatment tank 20, first liquid impregnation → first liquid removal → second liquid impregnation (reaction)
This process can be performed consistently, resulting in high work efficiency. Moreover, by alternately spraying high-pressure air and high-pressure water onto the surface of the porous material 50 after impregnating with the first liquid,
Excess first liquid can be effectively removed from the surface of the porous material 50 in a short time. Furthermore, first liquid impregnation,
When impregnating with the second liquid, the inside of the processing tank 20 is depressurized before impregnation, and the inside of the processing tank 20 is pressurized after impregnation to allow the processing liquid to penetrate deep inside the porous material 50. It is possible to impregnate even the core of the material. For example, with the conventional method, it was possible to impregnate only a thin plate of about 1 to 3 thicknesses, but according to the above method, even thick plates of 511!1 or more can be impregnated to the core. I was able to do this.
