Product Description:

EPDM waterproofing Rubber membrane

1. Product Description:

EPDM waterproofing membrane is made from ternary ethylene-propylene rubber. We adopts the world advanced equipment of cold feeding

extrusion and continuous vulcanization 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.

Q:What is the material on the insulation layer on the waterproofing membrane?
2, waterproof layer on the other construction layer construction, it is possible to pierce the waterproof layer, the appropriate protection Is necessary, the isolation layer can also play a protective role.
Q:Waterproof building materials after the construction of drums, bubble is what reason?
Causes and prevention of drums: Cause 1: If the membrane waterproof layer if the site is not solid, there is moisture, sunlight or artificial heat in the impact of the internal volume expansion, resulting in drums, the formation of the size of the bubble. Preventive measures: leveling layer should be kept flat, clean, dry, grass-roots treatment agent should be brushing evenly, which is to prevent the drum from the main measures. Raw materials in the transport and storage process, should pay attention to moisture and water. To avoid the rainy day, fog, big wind climate conditions under construction, to prevent grass-roots moisture. When the roof base should not be dry, and anxious to paving the membrane, the use of exhaust roof approach (exposed single layer of waterproofing membrane should not be used).
Q:1.2 thick synthetic polymer waterproofing membrane two weight how to count
Polymer waterproofing membrane is generally 1100 ~ 1400kg / m3, 1.0mm thick per square meter weight of about 1.1 ~ 1.4kg / m2, 1.2mm thick coil weight of about 1.3 ~ 1.7kg / m2, plus lap 10% , 1.2mm waterproof layer of the weight of 1.45 ~ 1.85kg / m2, if the adhesive paste, plus adhesive weight 0.2 ~ 0.4kg / m2, the total weight of about 1.7 ~ 2.3kg / m2, two about 3.4 ~ 4.6 Kg / m2.
Q:SBS waterproofing membrane sub-class I and II when to use what level to use a secondary level
Classification: According to physical indicators are divided into: Ⅰ (-20 ℃), Ⅱ (-25 ℃) type two categories; According to the fetal base can be divided into: polyester tires, glass fiber tire two categories; according to the surface material can be divided Waterproof sheet
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 are the requirements for the storage of waterproofing membranes?
Stand up to release the time can not put too long or how you put the deformation will be ..... so we generally stand
Q:Pvc waterproof membrane of the scope of application
PVC polymer waterproofing membrane Features: 1, PVC waterproofing membrane tensile strength, elongation is good, thermal size change rate is small; 2, anti-aging, resistant to ultraviolet radiation, chemical resistance, resistance to root penetration;
Q:Waterproof membrane in the escape when the full shop, empty shop, shop, shop what is the difference?
3, point shop paving the membrane, the membrane and the base layer with point-like bonding. Requires no less than five points per square meter of bonding. Each paste area of 100mm * 100mm. Between the point and the point should be equidistant plum-like distribution (the method can be used at the grass-roots level coating, coiling point of the membrane point coincidence).
Q:Sbs modified asphalt waterproof membrane polyester type Ⅰ type Ⅱ how to distinguish
These two kinds of materials from the current surface is exactly the same, if it is experienced people, you can through the tension on the sheet asphalt to determine the initial situation, if the domestic refrigerator can reach -25 ℃ low temperature, can also be low temperature flexibility Not broken after the initial judgment). To correctly determine the need for sample inspection.
Q:What is the difference between PET waterproofing membrane and BAC waterproofing membrane? What is the commonality? Is BAC a PET?
BAC is not equal to PET, carcass material is not the same, and BAC also fiberglass tire coil.
