What should you pay attention to before the construction of the basement waterproofing membrane?
5, plastic runway laying completed, maintenance and maintenance 7 to 10 days before they can be used normally.
4, the preparation of finished products: according to the pavement area required to calculate the semi-finished products, the required slurry and prepolymer were lifted to the console, according to batch release neatly. Place the desired vinyl particles and catalyst into the appropriate position on the table.
3, painting the bottom line: for the reasonable arrangement of the daily pavement workload, must first on the basis of the program according to set the program to draw a good dividing line, the entire track and field into pieces, and then press the block by pavement. In order to ensure smooth drainage and less joints and other requirements, the use of the first outer ring after the construction process.
2, the mold of the nail set: in accordance with the pre-scheduled area along the painted bottom line nail with polyethylene film wrapped wood mold. Mold to be flat, with the basic nail implementation, to prevent leakage material.
Plastic runway construction should pay attention to:
1, before the construction, must be on the asphalt concrete foundation for quality acceptance, acceptance criteria according to design standards and technical specifications, the plastic runway in the corresponding drainage facilities, can be used around the clock. The ambient temperature should be controlled at 5 ℃ ~ 38 ℃, to avoid below 5 ℃, 38 ℃ above the ambient temperature operation, the relative humidity control below 70%, the foundation requires a clean, according to the temperature and relative humidity to adjust the amount of catalyst The curing speed control appropriate. Color paste and prepolymer storage, the lid to be tightened, before use to detect moisture, qualified after use, the water in the foundation should also be controlled to avoid the bubble after the glue. Plastic pavement materials must be carefully checked when the quality inspection certificate and validity period.
