The metal engraved board not only plays the role of heat preservation and energy saving, but also plays a role in beautifying the decoration. In order to make the metal engraved insulation board serve us for a longer period of time, we have to do some waterproof measures on the metal engraved board material. Some waterproof methods, I hope to help everyone.

1. Use asphalt waterproofing membrane: It can be made of raw paper, fiber fabric, etc. It can be made into professional waterproof material.

2. A waterproof fortification: waterproof equipment with professional waterproof level.

3. Asphalt waterproofing membrane: Dip with asbestos material such as base paper, fiber fabric, fiber mat, etc., and the surface is sprinkled with powder, granular or flake material to make curlable sheet waterproof material.

4. High polymer modified bitumen waterproofing membrane: made of synthetic polymer modified asphalt as coating layer, fiber fabric or fiber felt is made of carcass, powder, granular, flake or film material Curlable sheet waterproof material.

5. Synthetic polymer waterproofing membrane: based on synthetic rubber, synthetic resin or a blend of the two, adding appropriate amount of chemical additives and fillers, etc., processed by different processes to form a curlable sheet waterproof Material, or composite of the above materials with synthetic fibers to form two or more layers of curlable sheet waterproof material.

6. Lengma Wangdi fat: cold asphalt cementitious material prepared from petroleum asphalt, filler, solvent, etc.

7. Base treatment agent: In order to enhance the adhesion between the waterproof material and the base layer, before the construction of the waterproof layer, the paint applied on the base layer beforehand. Partition: In order to reduce cracks, leveling and rigid waterproof layer on the roof The slit is pre-supposed on the rigid protective layer. The rigid protective layer is only made into a V-shaped groove on the surface, which is called the surface division joint. When the waterproof material is applied by the full-adhesive method, the construction method of the whole material is adopted for the coil and the base layer. .

8. Empty shop method: when laying waterproof membrane, the coil and the base layer are only bonded within a certain width of the surrounding area, and the rest of the construction method is not bonded.

9. Striping method: When paving waterproof membrane, the coil and the base layer shall be strip-bonded, and the bonding surface of each coil and base shall be not less than two, each width not less than 150mm.

10. Point-adhesive method: When paving waterproof membrane, the construction method of the coil or perforated coil and the base layer adopts point bonding, no less than 5 points per square meter, and the area per point is 100 mm× 100mm.

11. Hot melt method: The construction method of melting the hot melt of the bottom layer of the hot-melt waterproofing membrane by flame heater.
