Elastomer modified bitumen waterproofing membrane testing project Shandong Yuexu Building Materials Manufacturer's product quality is reliable, you can rest assured to buy. Generally speaking, there are two main types of adverse effects caused by floods. One is leakage and the second is damp. Among them, water leakage mainly occurs in places that are in direct contact with water, such as the toilets and kitchens between upstairs and downstairs. The damp situation is usually more complicated, and mainly occurs in slow leakage parts, such as the outer wall of the bathroom, and the window. nearby. Below, the editor of Shandong Yuexu Building Materials will introduce how to avoid water leakage and waterproofing.
It reflects the construction and use performance of waterproof membranes at low temperatures. Impermeable. Water impermeability refers to the performance of waterproofing membrane with a certain water pressure (hydrostatic pressure or dynamic water pressure) and no leakage for a certain period of time. It is the main quality index for waterproofing membrane to meet the requirements of waterproof function. Extensibility. The ability of the extensible waterproof coating film to adapt to the deformation of the base layer. After the waterproof membrane is formed, it must have a certain degree of extensibility to adapt to the deformation of the base layer caused by factors such as temperature difference, dryness and wetness, and to ensure the waterproof effect.

Elastomer-modified bitumen waterproof coiled material testing items. Use a paper knife to gently cut the release paper at a length of about 5m. Be careful not to scratch the coil. Slowly tear the unspread coiled release paper from the back, and at the same time The unrolled coil is slowly pushed forward along the reference line. Lay it while tearing the separator paper. After the paving is completed, roll back the remaining about 5m long coil of the previous trial paving, and paste it on the base layer according to the above method. Lifting method: Lay the cut coil on the base surface (that is, the bottom release paper facing upwards), after peeling off all the release paper of the coil, then scrape the cement paste on the bonding surface of the coil And the base surface to be laid position, then two people respectively lifted from the two ends of the coil, flipped and laid on the position to be laid. Coil paving. Rolling method: align the coiled material with the reference line and try to lay it.
When the base is monolithic concrete, use cement mortar leveling layer with a thickness of 20mm, the ratio of cement to mortar is 1:～1:3 (volume ratio), and the cement number is not lower. The leveling layer should be divided into grids and filled with sealing materials, so that cracking of the leveling layer can be avoided or reduced, so that when the structure is deformed or the temperature difference is deformed, the waterproof layer will not form cracks and cause leakage. The width of the seam is 20mm, the longitudinal and horizontal spacing of the split seams is not more than 6m, the position of the split seams is set at the supporting end of the roof panel, the junction of the waterproof layer and the protruding roof member at the corner of the roof, and the junction of the waterproof layer and the parapet Wait.
High-quality PET film. 40% thicker than similar products on the market, no wrinkles, tear resistance, no residual glue after peeling, high-quality asphalt raw materials, lean technology production, smooth and bright surface of the coil, super sticky. Super tensile strength. High-quality aluminum film, no wrinkles, tear resistance. The construction is more convenient. Self-adhesive waterproofing membrane, comes with a 5 cm wide excuse, convenient and simple construction, just one sticker, and never leaks. High-quality aluminum film. The coiled material and the adjacent coiled material are parallel overlapped. When the long and short sides are overlapped, the upper and lower coiled material overlap isolation film will be removed. Roll pressure exhaust. After the roll material is laid, use a soft rubber plate or roller to scrape from the middle to the other side of the roll material overlap direction and exhaust air to make the roll material fully adhere to the base surface. When lap laying the next coil, lift the release paper at the overlapping part of the lower coil, align the upper coil with the lap control line and stick it on the lower coil, scrape and exhaust the air to fully Full of sticky.
Polyethylene polypropylene composite waterproofing membrane, also known as polypropylene fabric waterproofing membrane, is a multi-layer polymer synthetic sheet material, which is based on polypropylene non-woven fabric and polyethylene as the main raw materials, and the performance is improved by adding additives It is a composite waterproof material with a reinforced protective layer, an anti-aging layer, and a four-layer sheet material integrated with the reinforced layer. Polyethylene polypropylene composite waterproofing membrane is a new type of waterproof material invented by the Chinese. Its appearance has triggered a huge change in waterproof materials.
The scope of application of SBS waterproof membrane. Polyester felt base elastomer modified bitumen waterproofing membrane is suitable for roofing and underground waterproofing projects of industrial and civil buildings. Glass fiber reinforced polyester felt tyre base membrane is suitable for mechanically fixed single-layer waterproof, but it needs to pass the wind load test. Glass fiber felt base roll material is suitable for general roofing and underground waterproofing projects with stable structure. Exposed use of waterproof membrane with opaque mineral granular material on the upper surface isolation material. Roofs, tunnels, highways, landfills, etc., are a kind of flexible building materials that can be rolled into a roll that can resist external rainwater and groundwater leakage. With the improvement of my country's technology, the product quality of some key enterprises has approached or reached the international advanced level of similar products. Waterproofing membranes need to be tailored according to the shape of the waterproofing base layer. For complex-shaped bases, multiple pieces need to be spliced. It is difficult to bond the overlapping parts of the waterproofing membranes, and the potential for water leakage is high. The waterproofing membranes should be installed after construction. The protection and maintenance after water leakage are also difficult problems. Any part of the penetrating damage, degumming. The waterproof membrane is mainly used for leaking glue on the building wall (even if there is only one place). The waterproof function of the entire connecting layer will be lost. If the damaged and defective parts cannot be found, partial repair is impossible. only redo waterproof.
