孔を有する多孔体を使用しているのが現状である。Porous bodies having continuous pores such as filter paper, non-woven fabric, knitted woven fabric, sintered body, and foamed body are mainly used as filters. The pore diameter of the continuous pores of the porous body is generally 5 μm or more. In the electronics industry and the like, there is a growing need to carry out finer filtration, and a porous body having continuous pores with a fine pore size of 1 μm or less, further 0.1 μm or less is required. However, it is extremely difficult to reduce the pore size of the continuous pores of these porous bodies. For example, in the case of fibrous materials such as filter paper, non-woven fabric, knitted fabric, etc., the diameter of the fiber to be used can be made small, but there is a limit to making the diameter of the fiber small. Can be reduced, but there is also a limit to reducing the particle size. Further, in the foam, it is extremely difficult to control the diameter of the continuous pores. Therefore, in the fine filtration, the present situation is to use a porous body having fine continuous pores made of special fibrin derivative or plastic which is unavoidably expensive.

均一化されるのである。The operation of the present invention will be described with reference to FIGS. In the figure, (1) is a porous body and (2) is continuous pores of the porous body (1). Gas is forced to pass through the porous body (1) in the direction of the arrow as shown in FIG. Fog of synthetic resin solution in the gas
When (3) is mixed, the fog droplets (3) form continuous pores (2) in the porous body (1).
As shown in FIG. 2, it is attached to the inlet of the continuous pores (2) by being pushed by the gas transmission pressure and spreads into the continuous pores (2) A (for example, with filter paper). If so, a liquid film is formed on the peripheral wall surface of the pulp fiber that constitutes the filter paper. After that, if the solvent of the liquid film is removed by the drying, as shown in FIG.
The wall surface (2) A of the continuous pores (2) of (1) is covered with the synthetic resin layer (5), so that the diameter of the continuous pores (2) of the porous body (1) is reduced. The thickness of the synthetic resin layer (5) can be adjusted by the mixing amount of the mist droplets (3) with respect to the gas and the flow rate of the gas mixed with the mist droplets (3). Can be reduced in diameter. And, although the pore size of the continuous pores (2) of the porous body (1) generally varies, the large pores of the continuous pores (2) have a small gas passage resistance and therefore preferentially mix the mist droplets (3). Gas that passes through, resulting in large pores
A liquid film is formed from (2) on the wall surface (2) A. Thus, the thickness of the synthetic resin layer (5) formed on the wall surface (2) A of the continuous pore (2) is approximately proportional to the size of the pore diameter of the continuous pore (2), and therefore the continuous pore (2) has The variation is made uniform as the size is reduced.

る。Therefore, in the present invention, it is extremely easy to reduce the pore size of the continuous pores of the porous body to a predetermined diameter by the synthetic resin layer and make it uniform, and provide the porous body for fine filtration at a very low cost. I can. Further, the porous body is reinforced by the synthetic resin layer and the chemical resistance can be improved.

Therefore, the treatment method of the present invention may be carried out with the filter paper (1) supported by the supporter (21) as shown in FIG. That is, a plurality of supporters (21) supporting the filter paper (1) are housed in a chamber (31) having a processing chamber formed therein, and the open ends of the supporters (21) are attached to the support plate () of the chamber (31). The suction path (34), which is set in the communication port (33) of (32) and connects to the suction side of the blower pump (35) as a blower, is connected to the bottom of the chamber (31), and the blower pump (3)
An air blowing path (36) communicating with the discharge side of 5) is connected to the side surface of the chamber (31), and a spray gun (37) of a synthetic resin solution is inserted in the middle of the air blowing path (36).

層(5)が形成される。When the blower pump (35) is operated in the above structure, the air in the chamber (31) flows into the supporter (21) through the filter paper (1) supported by the supporter (21) and the suction path (34).
The air is sucked into the absorption side of the blower pump (35) through the air blower, is discharged from the blower side, and is blown into the chamber (31) through the blower path (36). In this way, the air is passed through the filter paper (1) into the chamber (31), the suction path (34), the blast pump (35) and the blast path (36).
The synthetic resin solution is sprayed from the spray gun (37) of the air flow path (36) to mix the mist droplets (3) of the synthetic resin solution with the air. Thus, the synthetic resin layer (5) is formed on the wall surface (2) A of the continuous pores (2) of the filter paper (1) by the mechanism shown in FIGS.
