Product Description:

Product features:


The physical and mechanical properties of stability, durability and anti ageing capacity is good, its oil and solvent resistance and general-purpose chloroprene rubber be roughly the same.

1 Good heat resistance, cold resistance, can be in (-60-150 C) within the scope of use.

2 Extension and rate very high tear strength, shrinkage cracking of buildings or a strong ability to adapt.

3 The proportion of light (0.90~0.97), the appearance of uniform quality, has good flexibility and elasticity.

4 Good weldability, materials can be directly welded, is conducive to ensure weld quality. After welding to form an integral waterproof layer.

5 Good dimensional stability, heat shrinkage is small, the deformation is small, keep a good state during construction.

6 Environmental protection type. Does not produce harmful substances in the production, construction and use of the process, and can be recycled, does not produce construction waste.

 

Application range:


Applicable to all kinds of roofing, basement, tunnel, building waterproof engineering; civil and industrial building roofs and underground engineering, municipal, bridges, storage tank,

Waterproof subway, tunnel, dam engineering, especially suitable for durability, corrosion resistance requirements and easy deformation of the key waterproof engineering.

Q:What is BSB waterproofing membrane
SBS waterproofing membrane is: The thermoplastic elastomer is used as a modifier to make impregnated and coated materials, and the upper surface is covered with a polyethylene film, fine sand, mineral sheet (granule) or aluminum foil, copper foil and other insulating material made of curled sheet waterproof materials. Styrene-Butadiene-Styrene means: styrene-butadiene-styrene. SBS rubber modified petroleum asphalt for the invasion of the cover layer to polyester fiber non-woven fabrics, jute cloth, fiberglass mats were made for the fetal base, the plastic film for the anti-sticking isolation layer, the selection, ingredients, eutectic , Invasion, composite molding, curling and other processes processing production.
Q:Is the foundation pit waterproofing and the foundation pouring on the working face?
The current project is generally not in the bottom of the foundation to do the membrane waterproof, and generally will be changed into fine stone concrete or cement mortar to do rigid waterproof, in the base side and the basement wall to do the membrane waterproof, the base of the waterproof before the banding reinforcement, Basic side and basement wall waterproofing after basement wall construction is done
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:The difference between waterproof linoleum and waterproofing membrane
`Linoleum is a kind of waterproofing membrane! Belong to subordinate relationship. Felt is made of animal hair or plant fiber made of carpets or thick paper impregnated asphalt after the building materials, toughness, impermeable, used to do the roof, basement walls, foundations such as waterproof, moisture-proof layer. Also called oil felt. Approximately 2000 years ago, the most commonly used building waterproof material, has now been included in the scope of national banned building materials. At present, the construction of waterproofing membrane is large "elastomer modified asphalt waterproofing membrane" - the implementation of standards for the GB 18242-2008.
Q:Why is the top cover of the basement waterproofing? While the floor has to empty shop?
Waterproof construction methods are generally reflected in the construction drawings. If not, please consult the designer. A waterproof, full of sticky. Secondary, sticky or sticky. Construction waterproof with waterproof material. According to each of the different basement waterproofing, the construction team will have its own waterproof concept and specific construction requirements.
Q:Pvc waterproof membrane of the scope of application
The scope of products:     Polyvinyl chloride (PVC) waterproofing membrane due to the use of a unique product formula, the product life is far beyond the general waterproof material, the excellent performance of the membrane so that it is widely used in various fields of waterproof.    1, for industrial and civil construction of the roof waterproof, including planting roof, flat roof, slope roof.    2, the building underground waterproof: including reservoirs, dams, pools, drains and all parts of the basement waterproof.    3, tunnels, grain depots, civil air defense projects, landfill, artificial lake waterproofing.
Q:SBs waterproof cold sticky how to do?
4, paving sheet waterproof layer. Cold sticky construction of the joints is a weak part of the joints, in order to ensure the quality of seams waterproofing, each piece of the film should be posted when the standard line, that is, paving the first piece of paper before the grass, playing a good standard line, Along the shop paving, continue to pave the way, in the already prepared on the roll of the required width of the overlap and then play a good line, as a continuation of the standard line of sheet. Paving when asked adhesive or asphalt glue brush evenly, do not reveal the end, not accumulation, and need to be part of the solvent before they can roll pressure exhaust. Lap seam after the seam overflow overflow adhesive, should be flattened seal. At low temperatures, it is advisable to use hot air heating measures.
Q:What are the advantages and disadvantages of waterproofing membrane?
There are many types of waterproofing membrane, mostly flexible waterproofing membrane. Such as: SBS coil, PVC, EVA, ECB The advantages of the coil is simple operation, do not need any valuable equipment, the basic is the torch, hot melt welding machine, are not expensive, the shortcomings of the base is a higher demand, it is easy to be damaged, resulting in structural leakage.
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.
Q:What is the difference between PET waterproofing membrane and BAC waterproofing membrane? What is the commonality? Is BAC a PET?
PET refers to polyethylene terephthalate, PET film using polyester composite film as the surface material, coated with rubber asphalt adhesive material, with cement mortar paste or self-adhesive. Can be constructed on the wet base surface, the grass-roots requirements are low, with high bond strength, bonding effect is good, not channeling water and so on.
