Meanwhile, the system according to the present invention is based on the above-described configuration and operation, and the
At this time, since the modules need to process a large amount of information, a large amount of heat is generated. By cooling the modules, deterioration is prevented, and dust is not scattered during cooling, thereby preventing short circuit. .
To this end, the

Particularly, in the present invention, the concept of a pore membrane filter capable of automatically eliminating the clogging of the filter is used by using a filter, so that a semi-permanent lifetime can be ensured while a filter is fixedly constructed without replacement .

Then, when the air purging is completed, the
In addition, the filtered fine particles including the silicon dioxide powder separated and removed by air purge may be collected and sieved, and then only the silicon dioxide may be separated and reused.
In this way, the filter can be periodically filtered while preventing clogging through air purging, so that it can be used semi-permanently. Of course, carbon dioxide powder (SI) should be supplemented occasionally.
In addition, the
To this end, in the present invention, a reinforcing coating layer is further formed on outer surfaces of the
At this time, the reinforcing coating layer may be coated by a known coating method such as a spray method.
This reinforcing coating layer comprised 2.5% by weight of a water-soluble acrylic-modified urethane-alkyd resin, 3.0% by weight of zinc (Zn (NO 3 ) 2 .6H 2 O), 2.5% by weight of 1-chloro-2,3- 2.5% by weight of methyltrimethoxysilane, 3.5% by weight of an allophane powder having a particle size of less than 0.1 μm, 5.5% by weight of a resin solution having a polyurethane resin aqueous with decyl ether, and CH 3 COONa and 3H 2 O) 4.0% by weight, and 2.0% by weight formic acid, and with the zirconium oxide powder having a particle size of less than 6.0% 0.1㎛, thiocyanate copper 5.0 wt%, MEHEC (methylethylhydroxyethylcelluloe) 2.5% by weight , 8.5 wt% of a resin-silica composite, and the rest of the polycarbonate resin.
Here, the water-soluble acrylic-modified urethane-alkyd resin is added in order to impart adhesiveness to enhance adhesion with a material and to exhibit super water repellency.
In addition, zinc sulfate is added to enhance thermal stability by increasing the heat retaining force due to the formation of eutectic points. 1-Chloro-2,3-epoxypropane is a chlorine-based material having high reactivity and is used for stabilizing the reaction of the composition And methyltrimethoxysilane is added to enhance durability by enhancing the bonding force between emulsified materials by hydrophobicity.
In addition, alophene powder is a clay mineral generated from the weathering process of volcanic ash, which is an exceptionally amorphous clay powder which has no crystal structure and is added to enhance the VOC abatement effect. The resin liquid in which the polyurethane resin is decolorized with ether It is used to maintain adhesion and weatherability.
In addition, sodium acetate is added to enhance durability and heat resistance by strengthening the heat retention due to eutectic point formation, and formic acid is prepared by adding glycerin to the acid, .
The zirconium oxide powder is an amorphous white powder which is added as a kind of ceramics having a melting point of 2.677 캜, a density of 5.6 g / cm 3 and a Mohs hardness of 7 in order to increase the hardness and to strengthen the wear resistance, and the thiocyan copper is added to the copper- , And MEHEC (methylethylhydroxyethylcellulose) is added as a cellulose derivative composed of anhydrous glucoside monomer chain to enhance surface activity and chemical resistance.
In addition, the resin-silica composite is heated at a temperature of 600-800 ° C. in a state in which the colloidal silica and the acrylic polymer are immersed in a mixture of the acrylic polymer and the acrylic polymer in a weight ratio of 1: 1, To have a resin-silica composite form according to condensation.
At this time, the condensation reaction is carried out as follows, and the film adhesion and the texture density are drastically improved.
[Colloidal silica: - (HO-Si-OH-) n]
[Acrylic polymer: CH2CCH3CO-OH]
[- (HO-Si-OH- ) n + CH2CCH3CO-OH = - (HO-Si-O-CH2CCH3CO) - n + H 2 O]
In addition, the polycarbonate resin is added for high transparency and high hardness, strength maintenance and durability improvement.
A sample having such a coating layer was prepared, and water resistance was first tested to confirm the surface condition.
In the water resistance test, the sample pipe was immersed in a constant temperature water bath (60 ° C.), and the surface state was checked in units of 500 hours. As a result, no microscopic whitening, cracks, or white rust occurred.
In order to confirm the heat stability, the sample pipe was placed in a beaker, sealed (60 ° C), left in a dry oven for 5 days, and the state was measured. As a result, there was no surface reaction such as gelation.
In addition, to confirm the corrosion resistance, the sample pipe was tested according to KS-D-9502 (standard 240 hr) salt spray test method, and the result was good without occurrence of white rust.
