self-adhesive rubber bitumen waterproofing membrane is based on sbs and other elastomers and asphalt as the base material, polyethylene film, aluminum foil as the surface material or no film (double-sided self-adhesive), using anti-stick insulation layer of self-adhesive waterproof material. self-adhesive rubber bitumen waterproofing membrane is a kind of new building waterproof material with broad prospects for development. it has excellent impermeability, low temperature flexibility, extensibility and adhesion. in particular, it has self-healing, which is the general waterproof material does not have the advantages to ensure super waterproofing waterproof quality.
without adhesive, remove the barrier, you can firmly bonded to the grassroots. construction is convenient and the construction speed is very fast.
with rubber elasticity, excellent elongation, can be well adapted to the grass-roots deformation and cracking.
has excellent adhesion to the grass-roots level, the adhesive force is often greater than the shear force, with concrete, rubber, plastic metal, wood bonding.
self-healing, that the coil in the event of puncture or hard objects embedded, it will automatically and these objects heal as one, still help to maintain good water resistance.
construction safety, do not pollute the environment, construction is simple, easy to do on-site civilized construction.
in addition to the main body material, the polyethylene film on the surface material also has excellent water resistance and high strength (polyethylene polypropylene fiber membrane that only membrane waterproof), so waterproof double insurance.
corrosion resistance: the coil has good acid and alkali resistance, chemical resistance, in a variety of environments with excellent anti-aging properties.
super-coil and coil adhesive performance to ensure lap tight and reliable, seamless.
scope of application:
suitable for industrial and civil roofing, basement, swimming pool, reservoir, municipal engineering and subway tunnel waterproofing, but also for waterproof wooden and metal roofing works. especially suitable for unfamiliar use of open fire oil depot, chemical plants, textile mills, grain depot and other waterproofing projects.
the surface material is divided into three types: pe (polyethylene surface) for non-exposed waterproofing works; al (aluminum foil surface) for exposed waterproofing works; n (no film or double-sided self-adhesive) waterproof project; combined with polymer waterproofing membrane; according to the use of function is divided into exposed waterproof project (o) and non-exposed waterproof project.
specifications, area: 20m2, 10m2, 5m2 wide 920mm, 1000mm thick 1.2mm, 1.5mm, 2.0mm.
1, the grassroots requirements: waterproof layer should be solid, no hollowing, loose, sand, peel, no dust, debris, oil, rust, grassroots moisture content should be less than 9%.
2, node processing: the cornices, gutters, corner, water shedding, deformation joints and other special parts with self-adhesive membrane to do an additional layer.
3, spraying or spraying special primary treatment agent, after the primary treatment agent to dry, you can shop membrane.
4, lap width: long, short side lap width of 80mm.
5, the level of paving: first with ink lines in the grassroots pop up a baseline, and then from low to high paving, unwinding roll at the same time, opened the isolation paper, paving along the baseline, paving immediately after the rubber roller [ real.
6, vertical surface paving: the vertical surface from low to high paving, opened the side opened the isolation paper, paved with rubber roller compaction.
7, the first volume of the coil: closed at the head sealed with sealant, and then with a metal pressure bar, the fixing screw and the top seam to be sealed.
8, membrane-free waterproofing membrane and my company polymer composite construction.
9, waterproof protective layer: should be based on "roofing technical specifications" to do the protection layer.
