The binder may be polyvinyl alcohol (PVA), polyethylene glycol (PEG), or the like. The binder is preferably contained in an amount of 1 to 20 parts by weight based on 100 parts by weight of the ceramic raw material in the starting material.

As the pore-forming agent, an organic material such as cellulose, polymethylmethacrylate (PMMA), or a mixture thereof may be used. The pore former is preferably contained in an amount of 5 to 50 parts by weight based on 100 parts by weight of the ceramic raw material in the starting material.

The starting material may further include kaolinite powder so that the manufactured plate filter has high porosity and high strength characteristics. As the kaolinite powder, it is preferable to use a powder having an average particle diameter of about 100 nm to 40 μm, more preferably 300 nm to 30 μm. The kaolinite powder is preferably contained in the starting material in an amount of 0.5 to 45 parts by weight, more preferably 5 to 30 parts by weight, based on 100 parts by weight of the ceramic raw material.

In order for the plate-shaped filter to have high strength characteristics while having high porosity, the starting material may further include glass frit.

The starting materials are mixed. The mixing may use a process such as ball milling. Hereinafter, the mixing process by ball milling will be described in detail. The starting material is charged into a ball milling machine together with a solvent and mixed. The starting materials are mechanically mixed by rotating at a constant speed using a ball mill. The ball used for the ball milling may be a ball made of a ceramic material such as alumina or zirconia, and the balls may be all of the same size, or balls having two or more sizes may be used together. Adjust the size of the ball, the milling time, and the rotation speed per minute of the ball mill. For example, the size of the ball can be set in the range of about 1 mm to 50 mm, and the rotation speed of the ball mill can be set in the range of about 50 to 2000 rpm. Ball milling is preferably performed for 10 minutes to 48 hours. The starting materials are uniformly mixed by ball milling.

The mixed starting material is molded into a desired shape and dried. For the molding, pressure molding, extrusion molding, etc. may be used in consideration of the shape of the plate-shaped filter. The drying is preferably performed in an oven at 60-150° C. for 1-48 hours.

The molded result is charged into a furnace such as an electric furnace and a firing process is performed. The calcination process is preferably performed at a calcination temperature of about 1100 to 1600° C. for about 10 minutes to 48 hours. It is preferable to increase the temperature up to the firing temperature at a temperature increase rate of 1 to 50 ° C./min. If the temperature increase rate is too slow, it takes a long time to decrease productivity. Therefore, it is preferable to raise the temperature at a temperature increase rate in the above range. The firing is preferably performed in an oxidizing atmosphere (eg, oxygen (O ₂ ) or air (air) atmosphere). After performing the firing process, the furnace temperature is lowered to unload the fired product. The furnace cooling may be performed in a natural state by shutting off the furnace power, or may be cooled by arbitrarily setting a temperature drop rate (eg, 10° C./min). It is desirable to keep the pressure inside the furnace constant even while the furnace temperature is lowered. In the sintering process, the organic component is burned away when the temperature reaches 300 to 400 ° C. Since the sintering temperature is made at a temperature higher than the temperature at which the organic component burns, all the organic components are removed when the sintering process is completed, and pores are formed. The space where I am located and the space between the powder and the powder form pores, and the fired body that has undergone the firing process becomes porous.

To yield to the beam by mixing a boehmite sol and a TiO ₂ sol to the boehmite sol -TiO _2.

For the plate-type filter, a needle-shaped whisker may be coated or adhered to the surface for hydrophobicity or the like. For example, a paste or suspension including a needle-shaped whisker and a binder may be coated on the outer surface of the sintered body and heat-treated at a temperature of about 400 to 1000° C. to form it. The binder may be polyvinyl alcohol (PVA), polyethylene glycol (PEG), or the like. The binder is preferably mixed in an amount of 1 to 20 parts by weight based on 100 parts by weight of the needle-shaped whisker. In the heat treatment process, the organic component is burned out at a temperature of 300 to 400 ° C. Since the heat treatment temperature is made at a temperature higher than the temperature at which the organic component burns, all the organic components are removed when the heat treatment process is completed. A needle-shaped whisker is coated or adhered to the surface or pores of the plate-shaped filter, and the needle-shaped whisker suppresses water droplets from forming on the surface of the plate-shaped filter, thereby making the plate-shaped filter hydrophobic.
