Product Description:

1.Structure of Bentonite Waterproof Blanket Description:

Bentonite composite waterproof blanket (GCL) is a new type of geosynthetic materials. It is mixed by a natural grading sodium base bentonite particles and corresponding admixture. And by the special technology and equipment, it is fixed between the two layers of geotextile bentonite particles, made from bentonite waterproof blanket.It not only has all the characteristics of geotechnical material, but also has excellent waterproof performance (permeability).

2.Main Features of Bentonite Waterproof Blanket:

•Excellent waterproof performance.

Having all properties of geotextile material, such as separation, reinforcement and protection, filter, etc.

Easy for construction 

No affected by the limitation of the environment temperature, even under 0 ℃ can be construction too.

The cost performance is relatively high.

Being used in very wide range.

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:Sbs waterproof sheet and app coil how to see it
APP is a plastic body modified asphalt waterproofing membrane referred to, usually also known as APP modified asphalt waterproofing membrane, is a polyester felt, glass fiber mat or glass fiber reinforced polyester felt for the fetal base, random poly (APAO, APO, etc.) as a petroleum asphalt modifier, both sides covered with insulating materials made of building waterproofing membrane, product markings according to the following procedures: name, model, fetal base , The upper surface material, the lower surface material, the thickness, the area and the standard number, for example: 3mm thick, 10 square meters, the upper surface of the mineral pellets, the lower surface of the polyethylene film, polyester fetal base, Modified asphalt waterproofing membrane marked as: APP I PY M PE 3 10 GB18243-2008.
Q:3MM thick, one square meter waterproof membrane SBS price?
4, SBS modified asphalt waterproofing membrane is SBS rubber modified petroleum asphalt cited as the invasion coating, polyester fiber non-woven fabrics, jute cloth, fiberglass mats were made for the fetal base, to plastic film for the defense Sticky isolation layer, by the selection, ingredients, eutectic, invasion, composite molding, curling and other processes processing production.
Q:What is rigid waterproof, flexible waterproof?
2, flexible waterproofing refers to the waterproof layer in the external force, the waterproof material itself has a certain degree of stretch ductility (such as rubber-like flexibility), to resist the elastic layer of elasticity within the grassroots cracking, showing a certain degree of flexibility. Such as rubber-like membrane waterproof, polyurethane coating waterproof.
Q:SBS waterproofing membrane sub-class I and II when to use what level to use a secondary level
SBS modified asphalt waterproofing membrane, this coil has a good high temperature performance, can be -25 to +100 ℃ temperature range of use, a higher flexibility and fatigue resistance, and up to 1500% Elongation and strong puncture resistance, tear resistance. Suitable for cold areas, as well as deformation and vibration of large industrial and civil buildings waterproofing works.
Q:SBS modified asphalt waterproofing membrane and synthetic polymer membrane the same, not the same, what is the difference?
Polymer waterproofing membrane is a synthetic rubber, synthetic resin-based new waterproof membrane, with high elasticity, high tensile strength, elongation, heat resistance and low temperature flexibility, corrosion resistance, aging resistance, cold construction, Single-layer waterproof and long life and other advantages. Can be used cold sticky or self-adhesive construction
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: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.
Q:PVC waterproof membrane effect how
2, cold sticky method: the use of adhesive or miaolica for membrane and the grassroots, membrane and membrane bonding, and no need to heat the construction method.
Q:Polyethylene polypropylene waterproofing membrane forming. Secondary molding, what does it mean? How to distinguish?
The second compound is, first produced or bought from the market polyethylene film, by heating the polypropylene non-woven composite up. This method is not enough heating, non-woven stickers are not strong, heating is too high, the polyethylene film damage, polyethylene plastic through the second heating to speed up his aging. Further, the polyethylene film for secondary compounding, the proportion of the recycled plastic is too high, and the anti-aging property is lowered.
