Product Description:


Brief Introduction:

 

This waterproof membrane is made from ternary ethylene-propylene rubber. Weadopts the world advanced equipment of cold feeding extrusion and continuous valcanization technology.

 With the best performance among  high polymer waterproof materials, EPDM is of exceptional elasticity and will not split or crack under normal building movement.

Characteristic:


1)Good flexibility, creep properties and malleability, and the superior adapting ability to the deformation of the primary stress generated.

2). Tight adhesion between waterproof layer and basic layer, no channeling water. Having self healing ability after piercing.

3).Operation without heating. And possessing the reliability of pasting by itself with super strong connection of sheet materialand adhesion of same base.

4). Convenient and safe operation, no pollution to the environment.

 


Application:


1)  Make sure the roof deck smooth,clean and dry(Moisture<9%),then apply the surface of roof deck homogeneously with a kind bitumen paint till dry to start application.

2)  There are two methods in application:

One way is by heating and melting method---Heat the polyethylene film of the membrane and roof deck surface by heating and melting method to be nearly melted(not flowing),then install the membrane fully bonded to the roof deck with overlaps of 5-10cm.

The other way is by cold adhesive method---Pour the cold adhesive homogeneously on the roof deck then roll the membrane to install it to be fully sticked to roof deck.

By heating and melting method and by cold adhesive can be used in alternation in application as requested.

3)  After application,a full serious inspection is required to make sure no air bubble,no fold,no falling away etc to guarantee the waterproof life

Q:Polyurethane and SBS membrane waterproof
 Asphalt waterproof material with natural asphalt, petroleum asphalt and coal asphalt as the main raw material, with good adhesion, plasticity, water resistance, corrosion resistance and durability. Asphalt has been used as a waterproof material for more than 100 years and is widely used in civil engineering. Since the 1930s, oil asphalt gradually replaced the other asphalt, has become the main varieties of asphalt. Asphalt oil felt for the tire waterproofing membrane. At present, the varieties of linoleum oil asphalt felt, coal asphalt felt, glass cloth linoleum, glass fiber mats linoleum and linen linoleum and so on. Some countries also develop heat-resistant linoleum, porous linoleum, hot melt linoleum and low-burned linoleum. Conventional paper tires Asphalt felt is still the main varieties of waterproofing membrane, the bonding material is hot asphalt or in the hot asphalt mixed with inorganic or organic modified materials prepared asphalt glue (Methanol)
Q:How is the water level rated and how many grades are used?
3, roof waterproof level 3: Application: general building; Waterproof layer of reasonable use of life: 10 years; Waterproof layer selection of materials: should choose three asphalt four oil asphalt waterproofing membrane, polymer modified asphalt waterproofing membrane, synthetic polymer waterproofing membrane, metal sheet, polymer modified asphalt waterproof coating, synthetic polymer waterproof coating , Fine stone concrete, flat tile, felt tile and other materials;
Q:Modified asphalt waterproofing membrane SBS I G PE4 What does it mean?
SBS is called the elastomer modified asphalt waterproofing membrane, I on behalf of the model, GK is the tire base for the polyester tire base, PE four on behalf of the membrane for the double-sided PE film four mm thick.
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: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: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 kind of waterproofing membrane, waterproofing membrane is how to classify their respective advantages?
EPDM waterproofing membrane: Dura Pruff Germany imports, can be welded EPDM rubber waterproofing membrane, Wendi welding up to 470 ℃, can still be used after welding, support preform, material warranty 20 years And the welding tape is homogeneous with the material.
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:Roof SBS waterproofing membrane can not empty shop
Whether the waterproofing membrane is empty is determined by two aspects. 1, the construction site requirements. Such as the basement of the bottom of the membrane waterproof specifications require empty shop; deformation of the steel roof can be a small amount of sticky open shop or shop shop to adapt to structural deformation, but the coil to have a certain pressure.
Q:Polyethylene polypropylene waterproofing membrane forming. Secondary molding, what does it mean? How to distinguish?
In the appearance and mechanical analysis, these two processes is difficult to distinguish, a composite also has poor quality, the second compound can also be done better. So, only in the approval of the production line, to control.
