The shortcomings of elastomer modified bitumen waterproofing membrane in practical applications, the product has the comprehensive characteristics of anti-aging, high tensile strength, high elongation, wet roof construction, no protective layer exposed, convenient construction, and pollution-free. It is suitable for use as a waterproof layer for light energy-saving roofs, large factories and environmentally-friendly buildings. Performance characteristics. TPO waterproof membrane combines the performance advantages of EPDM and PVC, with the former's weather resistance, low-temperature flexibility and the latter's weldability. This material is different from traditional plastics. It shows high elasticity of rubber at room temperature and can be molded like plastic at high temperature.
Three-level residences, factories, warehouses, office buildings, shops, hotels, schools, etc. Four-level non-permanent buildings or temporary buildings. Roof waterproof grade and fortification requirements. The waterproof level of underground projects should be determined according to the importance of various projects and the requirements for waterproofing in use. The waterproof level of underground engineering is divided into four levels according to the allowable water leakage of the enclosure structure. Waterproof grade of various construction underground works. The name of the waterproof grade project.

Disadvantages of elastomer-modified bitumen waterproofing membrane: First, check whether the packaging meets the requirements. The membrane can be packaged in rolls with paper or plastic tape. There is a logo on the package, and the logo should include the manufacturer’s name, trademark, production date and batch number, production license number, storage and transportation precautions, etc. The marking must be numbered according to the method, sequence and code specified in the standard. Each roll of material has a mark, and the material on the roll has no mark or the mark is incomplete. Under normal storage conditions, the coils are stored for one year from the date of production, and the coils during storage must be re-examined before use before they can be used.
This situation is basically the same in the use of other waterproof materials. The main reason why the asphalt waterproof thermal method has strong vitality is that it uses multiple lines of defense, that is, a composite formed by multiple (3~4 layers) asphalt felt and multiple layers of hot asphalt can play a good overall role. The waterproof layer achieves complete water tightness, high breaking resistance and long-term durability. According to the survey, its durability can reach 80 years, so it has commercial reliability. These characteristics are not available in other waterproof material construction methods.
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 superior geographical location provides convenient conditions for the development of enterprises. The goods are strictly inspected before shipment. Small defects are not quality problems and do not affect the use effect. Hope to understand, the company can provide. The products sold by our company go through a strict quality inspection process before shipment to ensure product quality. Please check carefully beforehand. If there is a product quality problem, please submit the product picture to us. After confirming the problem, we will be responsible for the return. We assume.
If the types of SBS waterproofing membranes are distinguished according to the physical and mechanical properties of the membranes, they are mainly divided into two types, type Ⅰ and type Ⅱ, because when they are used, they can adapt to different temperatures, which can be divided into minus 20 degrees and minus two. The difference of fifteen degrees of adaptability. SBS waterproofing membrane has relatively good temperature resistance when used. It can be at a low temperature of minus 25 degrees to a high temperature of one. It has good elasticity and fatigue resistance, and can achieve up to 15%. The length of the body is resistant to severe cold and deformation, so it is very popular in buildings.
4: Insufficient adhesion. During waterproof construction, clean the base layer to ensure the strength of the base layer, choose the correct type of coiled material and construction method, and ensure the strong bonding force of the base layer. 5: The drying speed is too slow. The reason is that single-component acrylic coatings form a film through the volatilization of water. The high humidity and low temperature environment hinder the volatilization of water in the coating, so the drying speed is relatively slow. Yuexu Building Materials recommends: Strengthening indoor ventilation conditions can be more conducive to the use of water, or switch to polymer-modified bitumen waterproofing membranes made by Yuexu Building Materials for paving. Lay self-adhesive waterproof membrane. Unfold the roll material and align it with the reference line for trial laying, and pay attention to the paper isolation film facing down (when not using paper isolation film, the PE isolation film facing down). Plane roll paving: roll up the roll from one end, use a paper cutter to cut the paper release film from the roll at the length of 12, taking care not to cut through the roll. After the 12 rolls are in place, pull the torn release paper (film) head evenly and forcefully pull it back, while pulling and paving, pay attention to exhaust when paving, and the rolls are required to be laid tightly and firmly adhered to the base layer. .
