Q:DTM.E polyester composite waterproofing membrane, cheaper than the asphalt membrane?
Ouwei Jianke DTM.E polyester composite waterproofing membrane is the company according to GB50207-2002 "roofing quality acceptance norms", GB50108-2008 "underground engineering waterproof technical specifications", GB50208-2002 "underground waterproofing project quality acceptance norms" and Other waterproof engineering design Widely used in a new type of waterproof material,
Q:BS waterproofing membrane is modified? There are not a few thick drawings, how to do
For example, class Ⅱ waterproof basement waterproof, if only a SBS waterproofing membrane, then its thickness requires 4 mm; if there are other waterproof layer, you can use 3mm.
Q:Waterproof building materials after the construction of drums, bubble is what reason?
Reason 2: Construction, due to the construction of the membrane waterproof layer of paving is not true, so that part of the empty, remain in which to form a bubble. Control measures: in the asphalt waterproofing membrane construction, the first surface of the coil clean. When laying the web, the mastic should be painted evenly and carefully compaction work to enhance the cohesive force between the web and the base, the web and the web. High polymer modified asphalt waterproofing membrane construction, the flame heating to be uniform, full, moderate. Paving to roll forward while hot, while rolling with a pressure roller to exclude the air below the coil.
Q:How to choose waterproof membrane
Second, from the fetal base to identify the quality of the coil Generally from the product on the cross-section of visual inspection, the specific method can be purchased products by hand to tear it, observe the cross-section exposed fetal fiber, composite tires tear after the section of the grid cloth ribs exposed, this time It can be concluded that the product must be a composite tire coil, what kind of composite tire membrane with physical properties test - soluble content test to observe the exposed fetal base. And simple polyester tires, glass fiber tires after tearing the section only polyester or fiberglass fiber exposed.
Q:Asphalt composite tire flexible membrane is SBS
This is two kinds of materials, in addition to the same appearance, the same hot-melt construction, its physical and mechanical properties, anti-aging properties are very different.
Q:What is waterproofing membrane?
According to the brand classification Construction industry waterproofing membrane mainly Dike waterproof membrane, DuPont waterproofing membrane, Sicon waterproofing membrane, which the first two participating GB chart set. According to its main waterproof composition material can be divided into asphalt waterproof material, high polymer modified waterproof membrane and synthetic polymer waterproofing membrane (SBC120 polyethylene polypropylene composite membrane) three categories. There are PVC, EVA, PE, ECB and other waterproofing membrane Asphalt waterproofing membrane is in the base tire (such as base paper, fibrous fabric) dip on asphalt, and then spread in the surface of powder or sheet of the isolation material made of curled sheet waterproof material.
Q:How to use self-adhesive waterproofing membrane?
4) shop self-adhesive waterproofing membrane: the self-adhesive waterproofing membrane tile in the cement waterproof mortar. The web is parallel to the adjacent web, and the joints should be made as far as possible. (When the lap mode is used, the upper surface of the lower layer is separated from the upper surface of the membrane and the upper surface of the upper membrane is removed and then overlapped. 5) beat the surface of the membrane, mention pulp: with a wooden trowel or rubber plate tapping the surface of the coil, mention pulp, discharge the membrane under the surface of the air, so that the membrane and cement mortar close fit. 6) to put on: dry for 24 hours to 48 hours (depending on the specific time depending on the ambient temperature, under normal circumstances, the higher the temperature the shorter the time required).
Q:Sbs modified asphalt waterproof membrane polyester type Ⅰ type Ⅱ how to distinguish
These two kinds of materials from the current surface is exactly the same, if it is experienced people, you can through the tension on the sheet asphalt to determine the initial situation, if the domestic refrigerator can reach -25 ℃ low temperature, can also be low temperature flexibility Not broken after the initial judgment). To correctly determine the need for sample inspection.
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:Waterproof membrane in the escape when the full shop, empty shop, shop, shop what is the difference?
2, the shop laying the membrane, the membrane and the grass-based use of sticky. Requiring each web and the base of the bonding surface of not less than two, each paste width of not less than 150mm. The paste is located under the web and coil.
