Characteristics of elastomer modified bitumen waterproofing membrane

Elastomer-modified bitumen waterproofing membrane characteristics The shrinkage of the waterproofing membrane aging and decay will affect the waterproof layer, which is a shortfall in the previous waterproofing construction. Then it is necessary for us to find out the cause of the aging of the waterproofing membrane and find a solution . 　The reason for the aging of waterproof membrane. 　A, the aging of self-adhesive waterproofing membrane is related to the nature of the asphalt in the raw material. The quality of the asphalt fundamentally determines the aging time of the membrane. After research, we have found that coal tar pitch is aging faster than petroleum asphalt. 　B, the aging of the coil has a very large relationship with the local climatic conditions, and areas with large temperature changes will age quickly.





If there are cracks in the gutter and eaves, cut the waterproof layer at the cracks and cut the cracks in the base layer into a V-shaped groove with an upper opening of 20mm wide, and sweep it, then fill in the flexible sealing paste, and spread the width of the seam. A 200mm coiled material strip is used as a buffer layer, and then a waterproof layer of 350mm wide coiled material is fully pasted. 　The deformation joint is leaking. Phenomenon. 　 Water leaks along the cracks at the roots of the deformation joints and the seals on the joints. Cause Analysis. 　The detailed structure of the deformation joint is improper, the inner corner of the root is not made of arc and waterproof additional layer, and the top cover is not used as a buffer layer. After the cover is broken, the waterproof layer is leaked.

The characteristics of elastomer modified bitumen waterproofing membranes are mechanically fixed construction technology of waterproofing membranes. 　Mechanical fixing is to use special fixing parts, such as metal gaskets, screws, metal battens, etc., to mechanically fix the coiled material and other roof-level materials on the roof base or structural layer. Mechanical fixation includes point fixation and linear fixation. The bearing capacity and arrangement of the fixed parts are strictly designed according to the experimental results and relevant regulations. 　 Sundries and debris on the surface of the base layer. 　Laying a vapor barrier (polyethylene film).





Wall measurement, spring line, hang line. According to the building facade design and the external thermal insulation technical requirements of the external wall, the horizontal, vertical control line and expansion line, decorative stitching, etc. of the external doors and windows are popped up on the wall. Hang vertical datum lines at large corners of the building's outer walls and other necessary places, and hang horizontal lines at appropriate positions on each floor to control the verticality and flatness of the polystyrene board. 　Paste the overwrapped grid cloth. Wherever the exposed side of the polystyrene board is pasted, it should be treated with mesh cloth. The 80mm width of the grid cloth not less than 200mm wide is firmly pasted on the base surface with special bonding mortar, and the remaining grid cloth is turned over when the polystyrene board is pasted later.


Secondly, ensure that the ground is dust-free, soil-free, and oil-free. You can mop the ground carefully with a mop to remove all the dust, otherwise it will cause the waterproof membrane to crack and peel and affect the waterproof effect. 　. Shandong Yuexu Building Materials Co., Ltd. was established in 2008. It is a comprehensive company integrating the production, sales and construction of rubber products and building materials. The vast number of users across the country brings fast and convenient freight services. When coating the waterproof layer, the strength should be uniform, especially the joints, the male and female corners and the nozzle parts. 　Before painting and after painting twice, keep the perpendicular intersection angle, brush fully in place, the coating layer is thin, pay attention to the thickness at the nozzle and the corner of the pipe, do not exceed 1mm, so as to avoid dry cracking. 　After hours, perform sprinkling and maintenance. Do not damage the waterproof layer before condensing the water. Do not step on the water. You must also pay attention to the installation of sanitary ware. 　After completing the water storage test, the closed water level should be as high as possible, and the low water level should not be less than 20cm.





◆The detailed structure of the additional waterproof layer, such as yin and yang corners, gutters or gutters, water downs, pipe roots, deformation joints, post-cast belts and other special-shaped parts, should be provided with an additional waterproof layer. 　◆Seal the seam of the waterproof layer, the end of the coil and the sealing of the edge. 　◆The protective isolation layer is set on the outer surface of the waterproof layer to protect and isolate the waterproof layer. It is set according to the actual project or design requirements. 　The other components of the membrane waterproofing system should be configured scientifically and reasonably according to the type of project and the function of the building (structure).


The flexible waterproof material forms a film through a chemical reaction to isolate the building structure from the environmental water and achieve the purpose of waterproofing. 　Rigid waterproof material improves the impermeability of the concrete base by increasing the density and reducing the porosity. 　 Whether flexible waterproof materials and rigid waterproof materials are good or bad depends on whether the decoration environment is flexible or rigid. The ductility of the flexible waterproof material adapts to slight structural deformation, and is more suitable for the decoration of new and old houses. Use a welding machine to weld each lap edge. If double welds are used, air inflation testing is required. 　Detailed nodes. 　The coil sheet of the corresponding node is welded to the large-surface coil using a hand-held welding gun. There are many construction methods for waterproofing membranes, such as cold bonding method, hot air welding method, hot melt method, self-adhesive method, etc. 　Internally reinforced waterproof membrane manufacturers: Why are waterproof materials incessant after repeated bans, and even intensified? Industry insiders believe that overcapacity and ineffective supervision are two important reasons: On the one hand, there is a market where there is demand, and high profits make backward overcapacity lead to companies taking risks.
