Test temperature of elastomer modified bitumen waterproofing membranes At present, Shandong Yuexu Building Materials is a manufacturer specializing in the production of waterproofing membranes, with a complete range of products and favorable prices, which can meet the different needs of different users. Customers are welcome to come to know. Roof leakage is one of the common problems in general communities. It is very troublesome to destroy the decoration during repairs. The leakage of upper and lower floors will also cause disputes and conflicts between the owners, residents and the property company. Therefore, how to deal with such problems is very important. important. The following is the specific method compiled by Shandong Yuexu Building Materials Editor for everyone.
Pay attention to the product name and packaging mark. According to product standards, the outer packaging of the product should be marked with the company name, product mark, production date or batch number, production license number, storage and transportation precautions, and the product marking should be strictly in accordance with the standard, consistent with the product name, and must not be ambiguous Incomplete words or marks and no production marks. When choosing these products, users must pay attention to the product label and recognize the product name, because the label represents the identity of the product.

The test temperature of elastomer modified bitumen waterproofing membrane is more suitable for color steel roof. The self-adhesive coils of the same thickness and ordinary SBS, self-adhesive tensile strength and other indicators are not comparable to SBS. But self-adhesive has better adhesion and is easier to construct than color steel roof. In addition, the color steel house does not have high requirements for the tensile strength of the coil, and requires high cohesiveness. So it is better to choose self-adhesive. The temperature on the color steel roof is high, and the adhesion becomes better and better after being pasted, and the weight is lighter. 6 factors that cause leakage of self-adhesive waterproofing membranes.
Water leakage in a house is not a rare thing, it is more common in life, and roof leakage is also very annoying. It will not only affect normal life, but also damage some home properties, so when choosing waterproof materials , We must be cautious, so today we will introduce to you what roof waterproof materials are and how to do roof waterproofing related knowledge. The type of roof waterproof material. CH-108ZYY polymer cement waterproofing membrane CH-108ZYY polymer cement waterproofing membrane is a material often referred to as elastic cement.
Especially good waterproof materials for factory buildings and building roofs. At the same time, it can also be applied to some waterproof and moisture-proof projects such as reservoirs, toilets, basements, subways and so on. The use of polyethylene polypropylene composite waterproofing membrane: the waterproof construction base surface should be solid, flat, smooth, and there should be no looseness, sanding, cracks, warping and sharp protrusions, potholes, hollowing, etc. Mixture ratio: The weight ratio of cement to special rubber powder is 100 (cement): 1 (rubber powder): 50 (water) (appropriate amount of water). Proportioning method: Put the rubber powder into the container first. When Yuquan Waterproofing adopts pre-laid anti-adhesive waterproofing technology for tunnel waterproofing construction, concrete should be poured directly on the adhesive layer on the surface of the coiled material, so that after the concrete is cured, it will form a complete and continuous bond with the adhesive layer, so that the concrete is at the same time. Synthetic rubber is interlocked and airtight. Among them, the high-density polyethylene used in the coil is mainly to improve the strength of the waterproof layer, to resist the various stress effects brought by the tunnel structure, and to avoid cracks that affect the waterproof effect, and the self-adhesive layer is to provide bonding performance , And the weather-resistant layer is to avoid the smooth progress of the coil during construction.
Quality issues that should be paid attention to during construction. The roof is not flat and the leveling layer is not smooth, resulting in water accumulation. During construction, the line should be found and the slope should be placed. The line should be checked during the construction of the leveling layer. According to the design slope of the construction drawings, find the high and low points to achieve the slope, and connect the two ends with a line to be the slope of the drainage. Ensure that the leveling layer is straight and level, and prevent the slope from being too small or falling. The base layer is not dry when laying the coiled material, the shop is not careful, and the corners and corners are prone to hollowing.
◇Additional layer: the general parts are all pasted, and the deformation joints are allowed to be empty. ●The paving sequence is high span first, then low span, the same height, the first far and then the near, the same plane, and the paving starts from the low. ●Roofing direction. ◇Slope lt, 3% is laid parallel to the direction of the roof ridge. ◇Pave and paste with a slope of 3%～15% parallel or perpendicular to the direction of the roof ridge. ◇Slope gt, 15% or when subjected to vibration, it should be laid perpendicular to the direction of the roof ridge. ◇Parallel to the roof ridge lap seam downstream direction, when perpendicular to the roof ridge, the seam should follow the prevailing wind direction. Prevention. When constructing the roof leveling layer and rigid waterproof layer, a 30mm split seam should be left at the intersection of the parapet wall, and flexible sealing paste should be embedded in the seam. The inner corner of the root of the parapet wall is powdered into a circular arc. When the height of the parapet wall is greater than 800mm, a groove should be left, as shown in Figure 4. The ends of the coil should be trimmed and pressed into the reserved groove, and cement mortar or sealed after nailing. The material fills the groove tightly. When the height of the parapet wall is lower than 800mm, the ends of the coiled material shall be directly laid on the top surface of the parapet wall, and then reinforced concrete is used for the top.
