Q:What is the difference between polymer waterproofing membrane and cross film waterproofing membrane?
The use of high-quality pressure-sensitive adhesive adhesive layer, with the concrete base of the rapid combination of its excellent self-healing properties and local self-locking water performance greatly reduce the penetration rate. The polymer in the coil material reacts with the cement compound to form an interpenetrating network structure, which eventually forms a continuous mechanical bond and is permanently sealed on the cementitious material member.
Q:The difference between waterproof linoleum and waterproofing membrane
Waterproof membrane is mainly used for building walls, roofs, as well as tunnels, highways, landfills, etc., to resist the external rain, groundwater leakage can be curled into a roll of flexible building materials, as the basis for engineering And no leakage between the building connection, the entire project is the first waterproof barrier, the entire project plays a vital role. The main products are asphalt waterproofing membrane and polymer waterproofing membrane.
Q:3MM thick, one square meter waterproof membrane SBS price?
1,3MM thick, one square meter of waterproof membrane SBS prices in 20 --- 30 yuan range.
Q:How to distinguish whether the waterproofing membrane is polyester tires?
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:Can waterproof sheets be used on steel roof panels?
to resist the external rain, groundwater leakage can be curled into a roll of flexible building materials , As the engineering foundation and the building between the no leakage connection, is the entire project waterproof first barrier, the whole project plays a vital role.
Q:What is called a waterproof roll dry shop, wet shop
The biggest difference between the two is the same bonding strength, wet pad bonding strength is much larger than the dry shop method.
Q:What is the material on the insulation layer on the waterproofing membrane?
The isolation layer of the roof waterproof layer is generally set between the waterproof layer and the above rigid protective layer, and he has two roles. 1, the surface of the rigid layer (usually 40mm thick fine stone concrete) will have thermal expansion and contraction deformation, if the waterproof layer and the rigid layer is very good, rigid layer deformation will affect the deformation of the waterproof layer, so there may be waterproof Layer to produce a direct cracking or long-term fatigue damage, so the two tectonic layers should be set with a sliding function of the isolation layer;
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.
Q:What is the PEDM waterproofing membrane material?
It is widely used at home and abroad high-grade waterproof material for roof, underground, subway, bridges and require a higher waterproofing works.
Q:What is rigid waterproof, flexible waterproof?
4, rigid waterproof and rigid waterproof material is not the same concept, the same flexible waterproof and flexible waterproof material is not the same concept. Such as polyethylene polypropylene is a flexible waterproofing membrane, with polymer mortar (or bonded paste) bonded polyethylene polypropylene composite waterproof layer, it is rigid waterproof, because the mortar binder in the grassroots deformation will crack , The web between the web and the web can not withstand the deformation of the grassroots, and the water infiltrates from the lap to cause damage to the waterproofing layer.
