Description

TECHNICAL FIELD [0001] The present invention relates to a waterproof type sheet construction method for ozone-resistant tanks, and a waterproof type sheet construction method for the ozone-

The present invention relates to a waterproof type sheet construction method of ozone-resistant tank applied to an ozone treatment tank (including a chemical resistance tank) which is installed between a water purification plant and a drainage tank and supplies ozone to passing tap water to disinfect it.

For example, a water purification plant has a plurality of treatment tanks, and treats the water taken from the water source in a plurality of tanks to purify the water in the first tier. In other words, the tap water supplied from the water purification plant is the first water.

The tap water supplied from the water purification plant passes through the ozone treatment tank installed between the water purification plant and the drainage plant, and is treated with ozone and chlorine supplied from the ozone treatment tank and supplied to each household via the reservoir.

The ozone used in this disinfection process can not be easily used because it corrodes the inner wall of the ozone treatment tank in spite of excellent sterilization performance. Therefore, the inner wall of the ozone treatment tank is required to have strong ozone resistance. For this purpose, fluorine is used.

As an example, when a room temperature curing type fluorine paint was applied to the ozone treatment tank, the coating film deteriorated for only several months in an ozone environment of 3 ppm. That is, the room temperature curing type fluorine paint did not have the ozone resistance required in the ozone treatment tank.

As another example, a material excellent in ozone resistance includes a thermosetting fluororesin having a heat resistance of 400 占 폚. When the thermosetting fluorine resin was melted and applied to the ozone treatment tank at a high temperature, the surface of the ozone treatment tank was burnt and deformed. In other words, the workability and workability were low and it was not realistic.

As another example, there is a method in which a fluororesin sheet made of a thermosetting fluororesin is directly attached to the surface of the ozone-resistant tank. In this case, since the surface flatness of the ozone-resistant tank is poor, it is difficult to adhere the fluororesin sheet to the surface of the tank, and the entire fluororesin sheet can be separated from the surface of the ozone-resistant tank at the time of leakage.

The ozone-resistant tank 10 of the first embodiment can be applied to an ozone treatment tank or a chemical-resistant tank provided between a water purification plant and a drainage tank. Hereinafter, the ozone-resistant tank 10 applied to the ozone treatment tank will be described as an example for convenience.

In the ozone-resistant tank 10, tap water pre-treated in a water purification plant flows into the inlet 101, and the ozone is sprayed at a predetermined value (for example, 10 ppm) through the ozone supply port 102 and dissolved in the tap water , The tap water is sterilized and disinfected, and the treated tap water flows out to the outlet 103.

In order to avoid duplication of explanation, the method of waterproofing sheet construction of the ozone-resistant tank and the construction structure thereof will be described together with necessary parts.

FIG. 2 is a perspective view of a process for manufacturing a bonded sheet by bonding a waterproof sheet to a metal sheet applied to FIG. 1; FIG. Referring to FIG. 2, in a method of constructing a waterproof type sheet for ozone-resistant tanks, a first step is to prepare a joint sheet 50 formed by joining a waterproof type sheet 30 to a metal sheet 20.

Fig. 3 is a partial perspective view of the ozone-resistant tank applied to the ozone-resistant tank of Fig. 1, with the joint sheet provided on the inner wall thereof, and Fig. 4 is a sectional view taken along line IV-IV of Fig. 3 and 4, in the waterproof type sheet construction method of the ozone-resistant tank, the second step is to install the joint sheet 50 in the ozone-resistant tank 10. [

FIG. 5 is a partial perspective view showing a state in which a finishing sheet is attached to a connecting line of the bonding sheet of FIG. 3, and FIG. 6 is a sectional view taken along the line VI-VI of FIG. 5 and 6, in the waterproof type sheet construction method of the ozone-resistant tank, the finishing sheet 40 is attached to the joint sheet 50 in the third step.

Referring to FIG. 2 again, the first step is to prepare a bonding sheet 50 made of a thermosetting fluororesin and formed by bonding a waterproof sheet 30 to a metal sheet 20. That is, in the first step, the metal sheet 20 and the waterproof sheet 30 are stuck together and passed between the driving roll R 1 and the supporting roll R 2 to be hot-pressed to form an integrated bonding sheet 50. Therefore, the waterproof sheet 30 is integrated with the metal sheet 20.

The thermosetting fluororesin is also called a teflon sheet and has a melting point of 300 to 400 캜. The joint sheet 50 is installed on the bottom, the wall surface and the ceiling of the ozone-resistant tank 10 to impart a waterproof, corrosion-resistant performance and ozone resistance to the concrete structure of the ozone-resistant tank 10.

Referring again to FIGS. 3 and 4, in the second step, the bonding sheet 50 is fixed to the surface of the ozone-resistant tank 10 made of a concrete structure with the fixing member 210. The joint sheet 50 (and the metal sheet 20) eliminates the need for a sandblasting process for surface processing of the ozone-resistant tank 10 and facilitates the installation of the waterproof sheet 30. [

The joint sheet 50 (and the metal sheet 20) is fixed to the ozone-resistant tank 10 by the fixing member 210 so that the joint sheet 50 is integrally formed with the waterproof type sheet 30, The waterproof structure of the water tank is solidified.

For example, the metal sheet 20 may be formed of a steel sheet, a stainless steel sheet, a color steel sheet, and an aluminum sheet. That is, the metal sheet 20 may be formed of a steel sheet having a thickness of 0.3 to 0.5 mm. The joint sheet 50, to which the metal sheet 20 and the waterproof sheet 30 are joined, is wound in a coil state and supplied to the site so that it can be cut at the site.

In addition, since the bonding sheets 50 are firmly fixed to the ozone-resistant tank 10 by the fixing member 210, the ozone-resistant tank 10 can further maintain the waterproofness and the structure of the ozone-proof tank 10 more firmly.

The first step further comprises forming a sealing portion 230. The sealing portion 230 is press-fitted on the surface of the bonding sheet 50 to fill the sealing member on the head of the fixing member 210 disposed at a lower position than the surface of the bonding sheet 50, 50). Therefore, even though the fixing member 210 is used, the bonding sheet 50 can be waterproof and maintain the structure.

5 to 6, in the third step, a finishing sheet 40 made of a thermosetting fluororesin and having an adhesive layer 41 is attached on the butted portion of the both side joint sheets 50. Thus, the bonding sheet 50, the waterproof sheet 30 and the finishing sheet 40 adhere to the entire surface of the ozone-resistant tank 10 to complete the waterproof structure.

The third step is to attach the finishing sheet 40 in the vicinity of the connecting line of the adjacent bonding sheet 50 in succession to the surface of the bonding sheet 50 and the sealing part 230 located at the head of the fixing member 210 do.

The joint sheet 50 and the finishing sheet 40 are installed in the ozone-resistant tank 10 so that the concrete structure is corroded from the ozone sprayed into the tap water by blocking the tap water from dissolving the ozone dissolved therein from contacting the concrete structure prevent.
