Key points of construction technology of PVC soft board

1. Float the plastic soft board after the primer is dry: When the length of the room is not more than 20M, the plastic coil is generally opened along the length of the room. Measure the required length and number of stitches. Tailor the soft board. There should be a certain margin when cutting. When necessary, number the cut panels so that they can be seated when paving.

2. According to the numbered order, place the cut plates on the ground accurately according to the line drawing position.

3. Brush the adhesive: press one half of the plate in the longitudinal direction, turn up the other half of the plate, and apply a piece of glue on the ground and on the back of the plastic plate (scrape the glue with a comb-shaped scraper, the thickness should be thin and even). When painting the base layer, it should exceed the grid line by 10mm.

4. Paste the plastic board: When the adhesive on the base layer and the back of the plastic soft board is dry to not stick to your hands (about 10min), the plastic board is bonded to the base layer along the stylized line without applying external force. on. Paste the other side of the board and other boards in the same way.

5. Rolling: Use a special plastic scraper and a 25kg steel pressure roller to compact the plastic plate, drive out the air bubbles under the plastic plate, make the plastic plate and the base layer stick tightly, and make the edge of the plastic plate and the grid line Aligned. Lay sandbags on a smooth rolling foundation to facilitate the adhesion of the plastic board to the base layer.

6. The paving of the skirting line is the same as the surface layer of the ground. Note that the kicking board is generally not jointed.

7. V-shaped grooves are opened on the plastic plate: 24 hours after the plastic plate is pasted, the joint can be processed. Use a special V-shaped incision knife to sew a V-shaped notch on the board.

8. Plate seam welding: Use a special hot-air welding gun for welding plastic soft plates to weld the plastic electrode to the V-shaped groove. The air pressure should be controlled at 0.08～0.1Mpa and the temperature at 180～250℃. After the electrode is completely cooled, use a special planer to plan out the protruding part of the electrode. Repair welding should be performed when a false welding is found.

9. Wipe and wax: After the plastic board is laid, wipe it clean and wax.
