Q:Basement SBS Waterproof Coil Division I and II type What is the difference? How is the site identified?
SBS type I and type II differences are mainly low temperature flexibility and tensile extension
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 pressure-sensitive self-adhesive waterproofing membrane and sbs asphalt waterproofing membrane?
3, from the price   Pressure-sensitive self-adhesive waterproof membrane price is more affordable, quality assurance, as if there is a good product of home, such as macro cattle Xugong, the price is more affordable, quality assurance. And sbs asphalt waterproofing membrane is more expensive.
Q:Roof SBS waterproofing membrane additional layer needs to be wide
Waterproof membrane requirements have good water resistance, stability of the temperature change (high temperature does not flow, no blistering, not confuse; low temperature does not brittle crack), a certain mechanical strength, extensibility and resistance to fracture, to There is a certain degree of flexibility and anti-aging and so on.
Q:What is waterproofing membrane?
Waterproof membrane requirements have good water resistance, stability of the temperature change (high temperature does not flow, no blistering, not confuse; low temperature does not brittle crack), a certain mechanical strength, extensibility and resistance to fracture, to There is a certain degree of flexibility and anti-aging and so on. The waterproofing membrane is a curlable sheet-like waterproofing material. Is one of the important varieties of waterproofing materials in construction engineering.
Q:Polyurethane and SBS membrane waterproof
 Methyl methacrylate (methyl acrylate), acrylamide (acrylic), polyurethane (cyanide) as the base material of the grouting material can be used for underground engineering plugging waterproof.  Because plastic in the sun is easy to aging, so used in underground engineering, and polyurethane can be made of liquid, used to plug the water.
Q:What is the difference between construction non-vulcanized waterproofing membrane and vulcanized waterproofing membrane?
Non-vulcanized rubber waterproofing membrane: from SR or SR and asphalt blends by mixing, rolling made of coil, without vulcanization can use the product. The bonding between the coils and their bonding properties with the mortar is good, the manufacturing is convenient, the price is low, but the tensile strength is low. Can be divided into two types of rubber and rubber asphalt. Rubber type commonly used SBR and other SR production. Generally used for civil construction roof waterproof.
Q:What is sbs, app modified asphalt waterproofing membrane
Their characteristics and differences: First, SBS modified asphalt waterproofing membrane (polyester tires): SBS modified asphalt waterproofing membrane is SBS rubber modified petroleum asphalt cited as the invasion coating, polyester fiber non-woven , Jute cloth, glass fiber 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. Such as building dragon TJ-242 SBS elastomer modified asphalt waterproofing membrane. Features: The use of polyester felt (filament polyester non-woven) mechanical properties, water resistance, corrosion resistance is also very good; elastic and low temperature performance has improved significantly, the effective range of (-25 ~ 100) ℃; Excellent fatigue resistance. Use: for high-level and high-rise buildings of the roof of the single-layer laying and composite use, can also be used for basement and other waterproof and moisture, more suitable for the northern cold areas and structural flexibility of the building waterproof.
Q:How to use self-adhesive waterproofing membrane?
Construction Technology of Double - sided Self - adhesive Waterproof Coil First, the empty shop self - adhesive waterproofing membrane (mainly applicable to the basement floor and other suitable for the empty parts of the waterproofing works. Construction process: grass-roots treatment - → node strengthening treatment - → empty sheet - → long, short side lap bond - → quality acceptance 1) grass-roots treatment: grass-roots should be smooth, solid, no clear water, the grass-roots protrusions clean. 2) node to strengthen the processing: the node at the regulatory requirements to strengthen the treatment. 3) empty shop coil: coil length, short side of the overlap width of not less than 60mm. 4) long, short side lap bond: the length of the coil, short lap edge of the isolation film removed, 5) Adhesive on polystyrene board protection
Q:Is the foundation pit waterproofing and the foundation pouring on the working face?
3, you say waterproof and pouring concrete conflict? Do not conflict
