EPDM Rubber Waterproofing membranes

Products Description

EPDM Rubber Waterproofing membranes is a synthetic rubber, synthetic tire blends as the base

material, adding reinforcing agents, softeners, antioxidants, curing agents processing aids to promote

mixing by kneading, mixing, extrusion, rolling and curing, shaping and other processes can be

processed into sheet curling volume of new high elastic waterproof material.

Q:PVC waterproof membrane effect how
Coil waterproofing layer Roof construction process are: 1, thermal adhesive method: the use of thermal imitation fat for the membrane and the grassroots, membrane and membrane bonding construction methods
Q:Pvc waterproof membrane of the scope of application
3, with good weldability, seam hot air welding and the substrate into one; 4, with good water vapor diffusion, condensate easy to release; 5, low temperature flexibility is good, to adapt to the environmental temperature difference is good;
Q:On the roof of the waterproofing membrane paving the direction of what are the requirements
 As for the upper and lower layers are not allowed between the vertical paving, the reason is that after the paving more heavy joints, and heavy seam is the most vulnerable to leakage of weak parts.         Dragon waterproof experts to remind you: things always have a dual nature. In the southern region, the temperature is high, rainy days, to the web paving brought a lot of difficulties. In order to waterproof roofing, when the rain is easy to coil joints, in addition to less than 3% of the roof slope, the remaining slope of the roof coil should take the vertical roof direction paving.
Q:It is good for black roof with waterproof paper
Roof waterproof selection is generally: SBS modified asphalt waterproofing membrane and self-adhesive waterproofing membrane.
Q:How to distinguish the degree of sbs waterproofing membrane?
Method 3: If you do not want to send the laboratory, you can do the test in the refrigerator, as long as the refrigerator can meet the requirements of low temperature on the line. Method to refer to GB 18242 (2008) "elastomer modified asphalt waterproofing membrane". This method can only know the approximate situation of the coil.
Q:How to choose waterproof membrane
Third, from the physical quality of strict quality off From the appearance of visual inspection can only distinguish the composite tire coil, but failed to solve the selected products meet the quality requirements, which requires users to have the ability to test the technical institutions, according to the corresponding product standards for soluble content The physical properties of the factory test, with the soluble content of the project to control the product contains the amount of asphalt and modifier, but also to reveal the product used in the real face of the fetus can determine whether it is consistent with the product mark.
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:APP selection of asphalt waterproofing membrane selection points
3, Ⅱ type fiberglass fetal APP modified asphalt waterproofing membrane tension is higher, dimensional stability and heat resistance, good, but no elongation. Suitable for general and relatively cold areas and stable structure of the general engineering roof or underground waterproofing works.
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:Is the asphalt waterproofing membrane facing the side?
Because there are many types of self-adhesive waterproofing membrane, their use and construction methods are different, there are two main methods. 1, the normal self-adhesive paving method: the film directly paving or polymer cement cement wetting method, paste in the grass-roots level. The bottom of the floor floor of the building, in the concrete cushion with cement mortar leveling, and then the coiled surface of the membrane down, paste in the leveling layer, the roll surface pouring 50 thick stone concrete protective layer, Floor concrete. Wall construction, the film directly attached to the basement wall panels, and then do the protective layer on the outside. Commonly used modified asphalt self-adhesive waterproofing membrane, modified asphalt wet sheet is usually used in this method.
