Knowledge of waterproof layer

1. Waterproof layer durability: refers to the roof waterproof layer can meet the normal use requirements of the period.
2. A waterproof fortification: a waterproof layer with a separate waterproof ability.
3. Asphalt waterproof coil: The base paper, fiber fabric, fiber felt and other matrix materials are dipped with asphalt, and the surface is sprinkled with powder, granular or flake materials to make a crimeable sheet waterproof material.
4. Polymer modified asphalt waterproof coil: with synthetic polymer modified asphalt as the coating layer, fiber fabric or fiber felt as the matrix, powder, granular, sheet or film material as the coating material made of crimp sheet waterproof material.
5. Synthetic polymer waterproof coil: with synthetic rubber, synthetic resin or the blend of both of them as the base material, adding an appropriate amount of chemical additives and fillers, etc., through different processes to form a crimp sheet waterproof material, or the above materials and synthetic fibers and other composite to form two or more layers of crimp sheet waterproof material.
6. Lengma King Di fat: cold asphalt cementing material prepared by petroleum asphalt, filler, solvent, etc.
7. Base treatment agent: In order to enhance the bonding force between the waterproof material and the base, the paint is pre-painted on the base before the construction of the waterproof layer.
8. Partition joint: In order to reduce cracks, the joint is left in advance on the roof leveling layer, rigid waterproof layer and rigid protective layer. The rigid protective layer is only formed into a V-shaped groove on the surface, which is called the surface partition joint.
9. Full adhesion method (full adhesion method) : When the waterproof material is pasted, the construction method of the coil and the base is all bonded.
10. Empty paving method: When the waterproof coil is pasted, the coil and the base are only bonded within a certain width around, and the rest of the construction method is not bonded.
11. Strip bonding method: When laying waterproof coil, strip bonding is used between the coil and the base. Each sheet and the base bond surface is not less than two, each width is not less than 150mm.
12. Spot bonding method: When the waterproof coil is pasted, the coil or punched coil is used as the construction method of spot bonding with the base. There are not less than 5 points per square meter, and the area of each point is 100mm ×100mm.
13. Hot melt method: The construction method of using the flame heater to melt the hot sol of the bottom layer of the hot melt waterproof coil for bonding.
14. Cold bonding method (cold construction) : Adhesive or Leng Ma Wang Di grease is used to bond the coil to the base, the coil to the coil, without heating construction method. 15. Self-adhesive method: The waterproof coil with self-adhesive is used, and the construction method of bonding is carried out without hot construction or cementing material.
16. Hot air welding method: The construction method of using hot air welding gun for waterproof coil bonding and lap bonding.
17. Asphalt based waterproof coating: water-emulsion or solvent-based waterproof coating prepared with asphalt as the base material.
18. Polymer modified asphalt waterproof coating: asphalt as the base material, modified with synthetic polymer, prepared into a water-emulsion or solvent-based waterproof coating.
19 Synthetic polymer waterproof coating: with synthetic rubber or synthetic resin as the main film forming material, prepared into a single component or multi-component waterproof coating.
20. Matrix reinforcement material: refers to the chemical fiber non-woven fabric, glass fiber mesh fabric and other materials used in the coating waterproof layer.
21. Modified asphalt sealing material: asphalt as the base material, modified with an appropriate amount of synthetic polymer, adding filler and other chemical additives prepared by the paste sealing material.
22. Synthetic polymer sealing materials: mainly based on synthetic polymer materials, adding an appropriate amount of chemical additives, fillers and colorants, through a specific production process processed paste sealing materials.
23. Joint displacement: In the roof system, the joint gap changes due to temperature and external force.
24. Tension - compression cycle: reflects the sealing material in the process of use, due to temperature changes caused by joint displacement and subjected to periodic tension, pressure cycles, to maintain the ability to seal.
25. Backing material: In order to control the insertion depth of the sealing material and prevent the sealing material from sticking to the bottom of the joint, a deformable material is set between the bottom of the joint and the sealing material.
26. Block rigid waterproof layer: the waterproof cement mortar infiltrated into the waterproof agent is the bottom waterproof layer, and the middle is paved with quick materials such as clay bricks, and then the waterproof cement sand grouting is used to fill the joint and spread the waterproof surface layer.
27. Overhead insulation roof: thin products made of sintered clay or concrete, covered on the roof waterproof layer and set up a certain height of space, the use of air flow to speed up heat dissipation, play a role in the insulation of the roof.
28. Water storage roof: a roof that stores a certain height of water on the waterproof layer of the roof to play a role in heat insulation.
29. Planting roof: Covering the waterproof layer of the roof with soil or laying loose materials such as sawdust and vermiculite, and planting plants to play a role in insulating the roof.
30. Inverted roof: The roof with hydrophobic insulation material set on the waterproof layer.
31. Molded steel plate: light roofing material made of galvanized steel plate as base material, rolled by forming machine, and coated with various corrosion resistant coatings and color paint.
