The present invention is to finish the finish using a plastic tile in the construction of the tunnel, so that the tunnel can be constructed at a low cost while functioning as a finish having a common stone tile.

The manufacturing method of the plastic tile of this invention is as follows.

An injection process for forming an external shape by molding plastic in the form of a tile to be constructed, a degreasing process for removing foreign substances and oil generated in the tile during the molding process of the molded plastic tile as described above, and removing butadiene from the plastic tile And an etching process for forming holes, a neutralization process for removing residual Cr03 of the plastic tile, an active process for pd and sn precipitation of the plastic tile, and an active process for removing sn components of the plastic tile. 2 step, a chemical Ni process for imparting Ni metal powder of the plastic tile, a copper sulfate process for Ni plating and cushioning of the plastic tile, and a glossy Ni base plating and glossing of the plastic tile Semi-gloss Ni process, Glossy Ni process for Cr base plating and gloss of the above plastic tile The DUR Ni process, which gives the properties of high porosity and porosity, the Cr process for preventing the silver white gloss and discoloration of the plastic tile, the ion water purification process for removing the stain of the plastic tile, and the drying of the plastic tile. It is to proceed with the hot air drying process.

In the plastic tile manufacturing process of the present invention, the plastic tile is washed with water to remove contaminants or foreign substances generated in the plastic tile and to remove chemicals remaining in the plastic tile in the preceding process.

The present invention will be described in more detail as follows.

The plastic tile is molded into the required shape through a molding machine, and the injection process is performed to check whether there is a foreign matter in the appearance of the molded plastic tile, stamping phenomenon, or damage to the rack.

The plastic tile produced by the injection process is a chemical mixture of 10-15 ml / l of CP (centipoise) face agent and 20-100 ml / l of sulfuric acid in order to remove foreign substances generated on the surface of the plastic tile during the injection process. Degrease for 5 to 10 minutes at water temperature of 60 ± 10 ℃, to degrease the foreign substances and oil generated in the plastic tile.

In order to remove butadiene and form holes, the plastic tiles degreased as described above were subjected to 6 at a temperature of 70 ± 5 ° C. of 410-420 g / l chromic acid, 10 g / l Cr + 3 and 210-220 ml / l sulfuric acid. Etch for ~ 7 minutes.

The plastic tile etched as described above is neutralized with 5% hydrochloric acid at room temperature for 1 to 2 minutes and washed.

The plastic tile neutralized as described above was first neutralized for 3 to 5 minutes at a temperature of 30 to 35 ° C. of a chemical product of NP (neptunium) -8: 40 to 80 ml / l and hydrochloric acid 280 to 300 ml / l. It is to remove Cr03.

The first activated plastic tile as described above is to remove the sn (stannum) component generated in the plastic tile by secondary activation for 3 to 5 minutes at a temperature of 35 ± 5 ℃ of sulfuric acid 100 ~ 200ml / ℓ chemicals.

As described above, the plastic pile activated secondly is DK-A: 40-50 ml / l, DK-B: 40-50 ml / l, DK-C: 80-100 ml / l It is to give nickel metal component to plastic tile by chemical Ni process for 3 ~ 5 minutes at ℃.

The plastic tile imparted with the nickel metal component as described above is 30 to 30 minutes at 210 to 230 g / l copper sulfate, 50 to 60 g / l sulfuric acid, and a temperature of 20 to 25 ° C of a chemical of U-BAC 1.5 to 2.5 g / l. During the copper sulfate process, Ni plating and cushioning are formed on the plastic tile.

The plastic tile having a cushioning action as described above is 12 to 25 minutes at a temperature of 55 ± 5 ° C. of a nickel sulfate of 240 to 260 g / l, nickel chloride of 35 to 45 g / l, and a boric acid of 35 to 45 g / l of chemicals. It is to give corrosion resistance to plastic tile by gloss Ni process.

The plastic tiles imparted corrosion resistance as described above are polished Ni for 10 to 20 minutes at a temperature of 55 ± 5 ° C. of chemicals of 240-260 g / L of nickel, 35-45 g / L of nickel chloride and 35-45 g / L of boric acid. Cr plating and gloss are given to the process.

As described above, the polished plastic tile is made of nickel sulfate 240-260 g / l, nickel chloride 35-45 g / l, and boric acid 35-45 g / l with a chemical temperature of 55 ± 5 ° C. for 1 to 3 minutes. In the DUR Ni process to give high corrosion resistance and porosity.

Plastic tiles imparted high corrosion resistance and porosity as described above, Cr (chromium) process for 1 to 3 minutes at a chemical temperature of 55 ± 5 ℃ of chromium 210 ~ 250g / L and 0.5 ~ 0.8g / L sulfuric acid, plastic The tile prevents silver white gloss and discoloration.

As mentioned above, the plastic tile which prevented the silver white gloss and discoloration removes the stain which generate | occur | produced in the plastic tile through the ion water purification process through the ion water which generate | occur | produced through the ion water exchanger.

Plastic tiles removed stains as described above is to dry the surface through hot air drying.

The plastic tile produced as described above is used as the outer wall finishing material of the tunnel in the construction of the tunnel, and the tile is attached to the outer wall of the tunnel by using silicon, bond and the like having adhesive properties.
