2. A waterproof fortification: a waterproof layer with individual waterproof capabilities.
3. Bituminous waterproofing membranes: Dipping asphalt with base materials such as base paper, fiber fabrics, fiber mats, etc., and spreading powdery, granular, or sheet-like materials on the surface to make a curlable sheet-like waterproof material.
4. Polymer modified bitumen membrane: The synthetic polymer-modified asphalt is used as the coating layer, and the fiber fabric or fiber mat is made of carcass, powder, granular, sheet or film material. Flaky waterproof material.
5. Synthetic polymer waterproofing membranes: Synthetic rubber, synthetic resin or a blend of both as base materials, adding appropriate chemical additives and fillers, etc. Or combine the above materials with synthetic fibers to form two or more layers of curlable sheet-like waterproof material.
6. Lengma Wangdizhi: cold asphalt cementitious materials made from petroleum asphalt, fillers, and solvents.
7. Base treatment agent: In order to enhance the adhesion between the waterproof material and the base layer, the paint on the base layer is pre-applied before the waterproof layer is applied.
8. Separation seams: In order to reduce cracks, pre-existing seams on the roof screed, rigid waterproof layer, and rigid protective layer.
The rigid protective layer is only formed in the surface as a V-shaped groove, called the surface grid seam.
9. Full-stick method (full-stick method): When the waterproof material is applied, the coil and the base layer are all bonded together.
10. Blanking method: When laying waterproofing membranes, the coiled material and the ground layer are bound only within a certain width, and the remaining parts are not bonded.
11. Sticking method: When laying waterproofing membranes, the construction method of the strips and the base layer is used for sticking.
No less than two adhesive surfaces per web and substrate, each having a width of not less than 150mm.
12. Point sticking method: When laying waterproofing membranes, the coiled material or the perforated coiled material is applied to the base layer in a spot-like manner.
Adhesion per square meter is not less than 5 points, and the area per point is 100 mm×100 mm.
13. Hot-melting method: The method of using a flame heater to melt the hot melt of the bottom layer of the hot-melt type waterproof coil is used for bonding.
14. Cold-bonding method (cold construction): Adhesives or cold-mastic Wang Dizhi are used to bond the coils to the base layer, coils, and coils without heating. 15. Self-adhesive method: using a waterproof membrane with self-adhesive, no heat application, no need for cementing material, and bonding method.
16. Hot-air welding method: Hot air welding gun is used for the waterproof coiled material, lap jointing and construction method.
17. Bitumen-based waterproof coating: Water-based or solvent-based waterproof coating formulated with asphalt as base material.
18. Polymer modified bituminous waterproof coating: A bitumen-based material, modified with a synthetic polymer, formulated as an emulsion or solvent-based waterproof coating.
19. Synthetic polymer waterproof coating: A synthetic or synthetic resin as the main film-forming substance, formulated as a single-component or multi-component waterproof coating.
20. Carcass Reinforcing Material: It refers to the chemical fiber non-woven fabric, glass fiber mesh cloth and other materials reinforced in the coating waterproof layer.
twenty one. Modified bitumen sealing material: Asphalt base material, with appropriate amount of synthetic polymer polymer modified, adding filler and other chemical additives prepared paste sealant material.
twenty two. Synthetic Polymer Sealing Material: A paste-like sealing material that is made of a synthetic polymer material, added with an appropriate amount of chemical additives, fillers, and colorants and processed through a specific production process.
twenty three. Seam Displacement: In the roof system, the seam gap changes due to temperature and external forces.
twenty four. Tensile-Compression Cycling: It reflects the ability of the sealing material to maintain sealing after being subjected to periodic pull-and-pressure cycles during use due to temperature changes causing joint displacement.
25. Backing material: In order to control the depth of insertion of the sealing material and prevent the bottom of the sealing material and the joint from sticking, a deformable material is disposed between the bottom of the joint and the sealing material.
26. Block rigid waterproof layer: The waterproof cement mortar that penetrates into the waterproof agent is used as the bottom waterproof layer, and the middle is paved with quick materials such as clay bricks, and then the waterproof surface mortar is filled with waterproof cement mortar.
27. Overhead insulated roof: thin products made of sintered clay or concrete, covered on the roof of the waterproof layer and set up a certain height of space, the use of air flow to speed up the heat, play a role in thermal insulation of the roof.
28. Water storage roof: Stores a certain height of water on the roof waterproofing layer and acts as a heat insulation roof.
29. Planting roofing: Apply roofing materials such as sawdust, vermiculite and other loose materials to the roofing waterproofing layer and grow plants to provide thermal insulation.
30. Inverted roof: The hydrophobic insulation material is installed on the roof of the waterproof layer.
31. Pressed steel plate: It is a light roofing material made of galvanized steel plate, rolled by molding machine, and coated with various anti-corrosion and corrosion-resistant coatings and colored paint.

We are a manufacturer of automatic door openers that are designed to provide people convenience. Automatic Door Systems` drive to provide that level of service is but one of the reasons why automatic doors are becoming more and more popular. Our Automatic Sliding Door systems are modern, space-saving and elegant.
Automatic sliding doors have many basic functions some of which include: automatic mode with full opening width and/or reduced opening width, and exit only for traffic control.

Important safety functions such as safety sensors prevent the door from shutting if persons or objects are in the detection zone. If the door leaves are inhibited when closing, they are immediately re-opened or if the door leaves are hindered when opening, they are immediately stopped by a safety automatic reversing mechanism.
Our most popular sliding automatic door. Think of this as the go-to door for everyday automation needs. All components fully tested and pre-assembled at factory for fast, trouble-free installation.
