Test temperature of elastomer-modified bitumen waterproofing membrane Some waterproofing users have purchased cheap and inferior products in order to save money. Most of such waterproofing will continue to leak after one or two years. The high-quality sbs waterproofing membrane produced by regular manufacturers meets the inspection standards. Most of the waterproofing effects of such membranes will not crack or leak for more than 10 years. . Secondly, it depends on the quality. There are some tips that can be used when selecting on-site. Appearance label inspection: look at the model, manufacturer, address, certificate, production license number, implementation standard, negative temperature label, etc.
Paving of facades and large slopes: Since the adhesive force between self-adhesive coils and the base layer is relatively low, the coils are prone to slide down on the facades or large slopes, so on the facades or large slopes During the pasting construction, it is advisable to use a hand-held gasoline blowtorch to properly heat the adhesive on the bottom of the coil before pasting, venting or rolling. Large area coils are vented. After compaction, the overlapped part is rolled with a small hand-held pressing roller. Rolling from the inner edge of the overlap is carried out to exhaust air and stick firmly.

The test temperature of elastomer-modified bitumen waterproofing membrane is laid layer by layer from the cornice to the ridge. All kinds of membranes should be overlapped up and down, and the overlapping positions of multi-layer membranes should be staggered, and the upper and lower membranes should not be laid vertically. The order of applying coiled materials: When the waterproof layer is constructed, the joints should be made first, and the additional layer and the roof drainage are more concentrated (such as the connection between the roof and the water drop, the cornice, the gutter, the eaves, the corner of the roof, the end seam of the board, etc. ), and then construct upward from the lower elevation of the roof. When laying gutter and gutter roll materials, follow the direction of gutter and cornice to reduce overlap.
In addition, the viscous fluidity of the material is very high in the high temperature state, and when the material is subjected to the stress caused by the external force, it is prone to plastic creep. Low temperature can increase the brittleness of ordinary waterproof membrane materials. In a certain period of time, if the flexibility of the waterproof material is insufficient at a certain low temperature, as the internal stress of the material gradually accumulates, it may cause the material to crack and deform at low temperature. . The influence of rainfall (including rain and snow). Generally speaking, the amount of rainfall does not directly affect the performance of waterproof materials.
The product has strong bonding properties and self-healing properties, and is suitable for construction in high and low temperature environments. The self-adhesive waterproof membranes we use are mainly divided into single-sided self-adhesive and double-sided self-adhesive, which are characterized by a self-adhesive layer. Compared with the hot-melt method of pasting coils. Its major feature is that the waterproof membrane can be directly pasted on a certain required base surface without other auxiliary materials and tools, and the construction is very convenient. The cohesiveness of a type of self-adhesive coil comes from the properties of the main material of the coil, such as tireless self-adhesive coils, the modified asphalt of the entire coil itself has self-adhesive properties. metallic waterproofing membranes, thin steel sheets, profiled steel sheets, and galvanized steel sheets can be used as roof panels for waterproofing. Thin steel sheets can also be used in the basement of underground buildings. The waterproof effect is very good, and there will be no moisture or leakage. A decorative pattern commonly used in buildings. Paving method of waterproof membrane. Paving direction: When paving the waterproof membrane, it should be determined according to the roof slope and whether there is vibration on the roof. When the roof slope is lt, 3%, the membrane should be laid parallel to the roof ridge. When the roof slope is in the range of 3% to 15%, it can be laid parallel or perpendicular to the roof ridge, as gt. After 15% or vibration, the asphalt membrane should be laid perpendicular to the ridge of the roof. In addition, the direction of the waterproof membrane should be selected according to the actual situation.
After being pasted and exposed to sunlight, slight surface wrinkles and blisters may appear. This is a normal phenomenon and will not affect its waterproof performance, and will disappear once it is concealed. The waterproof layer should be concealed as soon as possible, and it is not suitable for prolonged exposure. Generally, it should be concealed within 24 hours after the completion of the waterproof layer. If there is a closed water test, the concealment time should be calculated from the end of the closed water test. The above is the construction plan of self-adhesive waterproof membrane provided by Shandong Yuexu Building Materials Editor. I hope it will be helpful to you. Our company integrates the production, scientific research, construction and sales of waterproof membrane. If you have Any need, you can directly call our hotline.
Polymer self-adhesive waterproofing membrane combines the advantages of polymer waterproofing membrane and self-adhesive membrane, greatly improving the performance of puncture resistance, weather resistance, self-healing, high and low temperature resistance, more excellent physical properties, and more stable chemical properties. During the construction of polymer self-adhesive waterproofing membrane, in order to prevent fire, it is necessary to do firefighting work in advance to ensure the safety of construction. Shandong Yuexu editor will take everyone to learn about polymer self-adhesive waterproofing. What fire fighting work should be paid attention to during the construction of the material. Domestic market analysis. According to the statistics of the construction department, the planned completed area of urban and rural residential buildings nationwide is 60 square meters plus dilapidated houses, old houses renovation and renovation, and the total construction area has reached tens of billions of square meters. The demand for waterproofing membranes is huge. China undoubtedly has a large demand for waterproofing membranes, and the largest market for waterproofing membranes. Therefore, investing in waterproof membranes at this time can create huge wealth. consumer analysis. With the improvement of people's living standards and the enhancement of the concept of household waterproofing, household waterproofing membranes have developed rapidly.
