Elastomer modified bitumen waterproofing membrane related articles: the difference between my country and foreign waterproofing enterprises, business models, government and market. Some friends have asked me these days, what kind of waterproof membrane do I need to use for waterproofing at home? But what I want to say is that waterproof membranes are not suitable for home improvement, so where are waterproof membranes mainly suitable? Waterproof coiled material is a roll of waterproof material made of thick paper or fiber fabric as the base and impregnated with asphalt or other synthetic polymer waterproof materials. It is mainly used for building walls, roofs, tunnels, highways, landfills, etc. It is a flexible building material product that can be rolled into a roll to resist external rainwater and groundwater leakage.
Government and market. Chinese enterprises. The government attaches great importance to the formulation of political documents. Including technology policies that promote product development. Planning outline. Guiding catalogs, promoting projects... and making regulations for improving the quality of waterproofing projects, but there is a lack of supervision and inspection mechanisms for implementation. Most companies have not really changed their minds. They use technological innovation as the driving force, adapt to the operating rules of the market mechanism, and rely on their own establishment to seek development in market competition. Foreign companies. In the operation of the market economy, the government completely liberalizes the enterprises and does not interfere with the production and operation of the enterprises. The two parties only have a tax relationship, and the enterprise can pay taxes in accordance with the law.

Elastomer-modified bitumen waterproofing membrane is used for additional reinforcement treatment on the roots of the water heater, the pipes out of the roof, the yin and yang corners and other parts. No matter what the reason is, we need to repair the leak on the top floor. First, we must find the location of the leak. If there is a crack, then cut the cement sand into a V shape, and then brush it with waterproof material. A layer of cement sand has to be large in area and high in thickness. There is also a slot on the edge of the cement sand, which will stick firmly. If the water is leaking from the water pipe, there may be a problem during the installation process, or it may be a problem with the material of the water pipe. This must be checked in detail.
The release paper can be peeled off during construction and it can be directly laid. The construction method of self-adhesive polymer modified bitumen waterproof membrane is similar to that of self-adhesive polymer waterproof membrane. But for the treatment of lap joints, in order to ensure the bonding performance of the lap joints, the lap joints are heated with a hot air gun, especially when the construction is performed at a lower temperature. This measure is more necessary. The self-adhesive method of paving waterproof membrane should meet the following requirements. Before laying the coiled material, the surface of the base layer should be evenly coated with the basic layer treatment agent, and the coiled material should be spread in time after drying.
Match the importance of the building. The high-quality and high-priced SBS modified bitumen coils and EPDM rubber coils are good materials for first- and second-level construction, and they are used for low-end construction. Such as construction sheds, short-term warehouses, disaster relief sheds, etc., to be demolished after one or two years, the use of high-quality materials is a waste. Pay attention to the operability of construction. Some waterproof materials have good physical properties, but they are difficult to construct and operate. Such as anti-adhesive coiled materials, it is difficult to seal the joints, and powdery materials are difficult to spread evenly, and it is more difficult to seal them when exposed or spread. Spray and brush should be thin and even, and can't leak white or thick skin. The cold base oil should be applied 1 to 2 days before the application, and the coil can be applied only after the primary treatment agent is applied and dried about 4 days. Laying of coiled materials. The laying direction of the coiled material: The laying direction of the coiled material should be determined according to the roof slope and whether there is vibration on the roof. In the house. When the surface slope is less than 3%, the coiled material should be laid parallel to the roof ridge. When the roof slope is 3%-15%, the coiled material can be laid parallel or perpendicular to the roof ridge. When the roof slope is greater than 15% or subjected to vibration, the asphalt coiled material It should be laid perpendicular to the roof ridge, and other parallel or vertical roof ridge paving can be considered according to the actual situation.
The roller material has a poor composition ratio, and carelessness will cause problems such as slow construction and hidden dangers. The additional layer of waterproof membrane is the leakage of possible weak nodes in the foundation cushion or roof waterproof construction process in advance, such as the Yin and Yang angle of the building structure, such as an extra layer coil, the Yin and Yang angle require a width of 500 mm, 250 mm on each side, up and down Paste, and then cover with a large surface coil, additional layer on the edge of the overlapping joints, building materials, the coil specification is 1000mmx10000 meters and 500mm wide half punching, the male and female corners are required to be rounded with 50MMR, for the top of the bottom brick, one brick can be Easy R angle after the second half. The choice of materials should be convenient for construction.
Corrosion-resistant, long-life flexible coil. When using a polymer waterproof substrate, you need to choose a good water-resistant adhesive. The thickness of the substrate should not be less than millimeters. Also, for coils such as polyurethane and silicone rubber waterproofing membranes, the thickness should not be less than millimeters. . Generally, cement-based inorganic rigid waterproofing membranes are suitable for each additional layer of waterproof layer indoors. The choice of bathroom waterproof membrane. Generally, the area of the toilet and bath room is relatively small and there are more yin and yang angles. The choice of waterproofing membranes for waterproofing projects should be able to choose based on this principle, which is to adapt to the basic level of change of shape and is beneficial to pipeline laying equipment. Anti-mold is also required. Second, impermeability is desired, and the coating film has no joint points. The membrane is a polymer self-adhesive waterproof membrane made of resin polymer (EVA, LDPE, HDPE, ECB, etc.) sheets as the main waterproof material, and a polymer waterproof substrate covered with a self-adhesive film. The coiled material self-adhesive layer and the anti-environmental change protective layer have self-healing function. After reacting and consolidating with the liquid concrete slurry, a gapless combination of the waterproof layer and the concrete structure is formed, preventing the hidden danger of water channeling, and can effectively provide the reliability of the waterproof system sex. Unique formula, non-asphalt-based reactive pre-laid polymer self-adhesive membrane waterproofing membrane is made of non-asphalt-based self-adhesive rubber compound and polymer sheet.
