Elastomer modified bitumen waterproof membrane production process brand Yuexu tear strength 800N core material bitumen. Specification: 3mm2mm4mm poly 3mm poly 4mm. Construction process: basic requirements: the base layer must be level, clean, and dry, and the moisture content should be less than 9%, and then evenly paint the surface of the base layer with primer, and then pave it after it dries. Hot melt method: Use a flame spray gun or other heating tools to aim at the bottom of the coil and heat it evenly. When the asphalt on the surface begins to melt and become black and shiny, bake the coil while laying it, and compact it with a pressure roller.
At present, the majority of ordinary multi-storey residential houses under construction in Henan are sloping roofs. The construction period of sloping roofs accounts for a large proportion of the entire construction period of the project. The roof structures are all cast-in-place reinforced concrete roofs. It is more complicated and has more detailed processing. If the detailed processing is not in place or the pouring quality control is not in place during pouring, it will directly affect the quality of the roof construction. The reason is that it is more convenient and more thorough to do waterproof measures later.

The production process of elastomer-modified bitumen waterproofing membrane should be considered from two perspectives. One is the material problem, and the other is the construction problem. Waterproof materials. It depends on several materials, whether it is non-standard material or national standard material. Someone will do it for more than 10 yuan cheaper. Qualified, a piece of material costs about 40 yuan. Take the traditional SBS modified bitumen coils, ranging from 100 yuan per roll to 600 yuan per roll, and the price of contracting materials for the construction team ranges from 20 yuan per square meter to 60 yuan or even 70 yuan per square meter. .
No less than 5 points are bonded per square meter, and the area of each point is 100mm100mm. 1 What is hot air welding. Using hot air welding torch for waterproofing membrane, the construction method of lap bonding. 1 What is the external defense external paste. is to paste the waterproof layer of the coiled material (paint) on the water-front surface of the structure. For external protection and internal sticking, the permanent protective wall is built first, and then the waterproof layer of the coiled material (paint) is pasted on the protective wall. Pre-construction preparations.
Storage method. Double-sided self-adhesive polymer modified bitumen waterproofing membrane should be protected from the sun and rain, and ventilation should be paid attention to. The storage temperature should not be higher than 50℃, store it upright, and the height should not exceed two layers. Polymer self-adhesive waterproofing membrane is a new type of waterproof material that has only emerged in recent years. Compared with similar waterproof materials, it has the advantages of simple construction, strong waterproofness, and relatively environmental protection. Shandong Yuexu building materials manufacturer tells you that polymer self-adhesive waterproofing membranes are different from ordinary waterproofing membranes in the following points. What is the price of waterproof membrane. Waterproof membrane is divided into SBS, APP modified bitumen waterproof membrane and polyethylene, polypropylene fiber waterproof membrane. The cost of waterproofing membranes is generally between 20-40. 2, such as SBS, APP type I modified bitumen waterproof membrane material price: 26~30 yuan/㎡, the price of II type modified bitumen waterproof membrane material: 32~36 yuan/㎡. Polyethylene polypropylene waterproofing membranes are mainly classified in grams per square meter, which can meet the needs of the nationwide molded polyethylene polypropylene waterproofing membranes. The price is generally more than 28 yuan/㎡.
The root of the parapet is leaking. Phenomenon. The waterproof layer is hollowed along the inner corners of the roots of the parapet, cracks, cracks in the parapet masonry, cracks in the top, the gable is pushed out of the wall, and rainwater pours into the inner wall from the gap. Cause Analysis. The leveling layer, rigid waterproof layer, etc. are directly close to the parapet wall during construction, and no splitting joints are left. The long parapet masonry does not have expansion joints. Under the action of temperature difference, the gable and parapet walls are cracked, and the roots of the parapet wall are not Make an arc according to the regulations, and the waterproof layer of the rolled material is not used as a buffer layer according to the regulations. The end of the rolled material is not sealed well, causing cracks, opening and water leakage.
To understand what factors determine the performance of waterproof materials, we must first understand the structure of the waterproof membrane. SBS waterproof membrane is composed of a 3-layer structure, the middle layer is polyester non-woven fabric, and an asphalt-based adhesive layer on each side. It is the effective structural layer that ultimately determines the waterproof performance, and the national standard products that meet the waterproof design requirements can be used safely and securely. Never take the thickness of the material as a standard for consideration. Moreover, lighter and thinner material production processes are now generally promoted in the world. After submerging the silicone board in the water, the study found that the closer to the surface of the waterproof film, the more difficult it is for the salt to dissolve. After analysis by professional and technical personnel, this is due to the strong pull of water molecules near the surface of the highly hydrophobic waterproof material, which makes the salt substances difficult to dissolve. Therefore, improving the surface structure of waterproof materials can develop materials that are both waterproof and easy to clean off surface dirt, reducing the difficulty of modern waterproof engineering construction.
