Product Description:



Introduction for EPDM Waterproofing Membrane:                                                                                 

Waterproof membrane for roof adopt the international advanced level cold feed extrusion continuous vulcanization process for the integration of production equipment and technology so that the system density of products is better and the products have no bubble sooth surface, no performance difference between vertical and horizontal.

 

Characteristic of EPDM Waterproofing Membrane:                                                  

· with adhesive tape on the overlap for the sealing of junction,convention for application.

· Excellent weather resistance, corrosion resistance, anti-aging, antioxidant. 

· Excellent waterproofing performance and encase nail holes.

· Good permeability, can be in damp base surface construction, make the maintenance structure internal water vapor rapidly eduction, avoid effectively mould and condensing formation

Q:What is the difference between construction non-vulcanized waterproofing membrane and vulcanized waterproofing membrane?
The advantages of the present invention Is: 1. elongation of permanent deformation is good, after stretching the rebound rate is small, no internal stress, can be fully adapted to the external factors caused by the deformation, there is no accelerated aging after the problem, so the service life can be improved 2-3 Times more than. 2. elongation, up to 1000%. 3. Natural vulcanization of a long time, can reach more than 10 years. 4. Good resistance to low temperature performance. 5. Bonding performance is good. 6. Production costs and operating costs are lower than other existing products.
Q:What are the requirements for frost resistance of basement floor polymer waterproofing membranes?
Sbs elastomer modified asphalt membrane is -25 degrees,
Q:How to distinguish the degree of sbs waterproofing membrane?
Method 1: Look at the product packaging instructions or factory inspection report, if it is type Ⅰ coil, low temperature flexibility is -20 °, if it is type Ⅱ coil, low temperature flexibility is -25 °.
Q:It is good for black roof with waterproof paper
Roof waterproof selection is generally: SBS modified asphalt waterproofing membrane and self-adhesive waterproofing membrane.
Q:Floor tiles on the terrace leak, can be directly on the brick shop SBS coil and then cast the cement?
3, the first waterproofing process: slotted, filled, waterproof package, neutral weather-resistant structural adhesive, this process has a wide range of use, waterproof effect, long life, convenient construction and other characteristics, as long as the use of this A process, the terrace is almost no water leakage. But this process also has its shortcomings, it is only suitable for more standard terraces and walls, such as foam insulation wall, wall mosaic wall, physical brick wall. On the contrary, the structure of the terrace, such as glazed tiles, semi-inclined wall, etc., is not suitable for this process.
Q:APP selection of asphalt waterproofing membrane selection points
1, I type polyester tire or glass fiber tire modified asphalt waterproofing membrane PET higher heat resistance, but low temperature flexibility is poor. Suitable for non-cold areas for general construction works of the roof waterproof layer. The waterproofing material of the upper surface material of polyethylene film or fine sand shall not be exposed.
Q:About asphalt waterproofing membrane
2, SBS refers to the use of SBS rubber into the asphalt, the performance of the asphalt to improve the use of polyester felt or fiberglass as a tire base, the surface with polyethylene film or other materials for the isolation layer. The general thickness of 3mm 4mm.
Q:SBs waterproof cold sticky how to do?
5, protective layer construction. In order to shield or reflect the sun's radiation, to extend the life of the waterproof layer of the membrane, in the waterproof layer is completed and checked after passing, should be coated on the surface of the waterproof layer of adhesive, side of the expansion of the expansion of silica powder protective layer, or uniform Brush the silver or green paint as a protective layer.
Q:Do you know how many square meters of waterproofing membrane to send a set of tests?
Chlorinated polyethylene-rubber blend of waterproofing membrane: 250 volumes for a group, the lack of a group also.
Q:Sbs waterproof sheet and app coil how to see it
SBS full name is: styrene - butadiene - styrene block copolymer. SBS is an abbreviation of elastomer modified asphalt waterproofing membrane. It is also known as SBS modified asphalt waterproofing membrane. It is made of polyester felt, fiberglass felt or glass fiber reinforced polyester felt as the base, styrene-butadiene (SBS) thermoplastic elastomer as a petroleum asphalt modifier, both sides covered with isolation materials made of building waterproofing membrane, the product implementation of the standard GB18242 national mandatory standards. Product markings are carried out according to the following procedures: name, model, tire base, upper surface material, lower surface material, thickness, area and this standard number, for example: 3mm thick, 10㎡ area, the upper surface is mineral pellets, the lower surface is poly Vinyl film, polyester tread base, type I elastomer modified asphalt waterproofing membrane marked as: SBS I PY M PE 3 10 GB18242-2008.
