The code name of elastomer modified asphalt waterproofing membrane is various industrial and civil building basement roof and roof waterproofing projects. Roofing projects include planted roofs, concrete roofs, sloped roofs, light steel structure roofs, and exposed and non-exposed roofs. Subway, highway and railway tunnels, bridges, civil air defense projects, etc. Waterproofing of municipal projects such as large granaries, beam-making yards, garbage landfills, artificial lakes, and various pipe trenches. Process flow. TPO waterproof membrane construction steps. The base surface is cleaned, and the polyethylene film is laid. The insulation board is pre-laid with TPO waterproof coiled material. Fasteners are used to fix the TPO waterproof coiled material.
It has good high temperature resistance and can be used in the temperature range of -25 to +100℃. It has high elasticity and fatigue resistance, as well as up to 1500% elongation and strong puncture resistance. Tear ability. It is suitable for waterproofing projects in cold areas and industrial and civil buildings with large deformation and vibration. The product is suitable for waterproofing works of I and II grade buildings. Specifications. According to the different tire base, it is divided into polyester tire (PY), glass fiber tire (G) and glass fiber reinforced polyester felt (PYG).
Waterproof membrane VaDI8TX8x
The code name of elastomer modified bitumen waterproofing membrane. Some products are mixed with waste rubber powder in the bitumen, which leads to a decrease in bonding performance and a shortened storage period. Exposed use should be used as a protective layer. The characteristics, performance and application technology of this membrane are different from those of polymer modified bitumen waterproof membrane covered with self-adhesive layer. EPDM (vulcanized) waterproof membrane. Features. High tensile strength, excellent aging resistance and long service life. Good elasticity, high elongation, and strong adaptability to expansion or cracking deformation of the base layer.
The roll material made of waste rubber powder has a strong pungent smell, which will be stronger if heated with an open flame. It's a touch. Tactile feel of the folded coil: It is to judge the hand feel. SBS coil is relatively soft, elastic, and has good viscosity. It is tightly combined with the tire base and shows excellent low temperature resistance. Inferior ones have no elasticity and are very easy to break or separate the asphalt from the tire base. Take a sample of coiled material and fold it repeatedly. If it breaks and the asphalt separates from the tire base, it is a poor quality product.
Product name: Self-adhesive rubber asphalt waterproofing membrane. Raw material: synthetic rubber/tackifier/asphalt. Type: Self-adhesive type. Features: No adhesive is needed, and it is firmly bonded. Core material: Polyester base tire and tireless. Tensile strength: excellent. Specifications: 1*20m. Thickness: 2mm impermeable. Yuexu's five characteristics of self-adhesive coils. High and low temperature resistant and waterproof: The strong film can withstand low temperature up to -40°C and high temperature resistance up to 93°C. High cohesiveness and self-healing property: It does not need to be heated to melt, just tear off the isolation layer, it can be firmly bonded to the base layer, and the construction is convenient and fast. Unified national telephone. This article link address/. TPO background understanding. TPO waterproof membrane is a new type of waterproof material popular in the United States and Europe, and it occupies an important position in the waterproof market. In 1991, Europeans used it for roofing and entered the American market in the late 1990s. After that, it has developed rapidly. By 2008, the market share of TPO roofing systems exceeded EPDM (EPDM), and it was already in the North American roofing market. In 2017, the share exceeded 40%.
At the same time, fire prevention measures should be taken during construction to eliminate potential safety hazards. How to distinguish the thickness of SBS waterproof membrane. SBS waterproof membrane packaging should have the following marks, if there is no or incomplete marks, it is a violation of the production license. If it is marked separately, it is other products, such as composite tire flexible waterproof membrane, etc. SBS waterproofing membrane is the thicker the better the waterproof performance. If the waterproof membrane is thicker, its puncture resistance will be stronger, and abrasion resistance, weather resistance, and aging resistance will increase accordingly.
In addition, the short side and the two adjacent webs are long, and the overlap width of the short side does not meet the requirements, which often results in leakage at the joints of the roofing membrane waterproof layer. The lap joint method should be used when laying and pasting the coiled material. If it is parallel to the lap joint of the roof ridge, it shall be lapped in the direction of flowing water, and if it is perpendicular to the lap joint of the roof ridge, it shall be lapped in the direction of high frequency wind. The direction of laying the coiled material should be based on the roof slope. If the roof slope is less than 3%, it should be laid parallel to the roof ridge. If the roof slope is 3%~15%, it can be laid parallel or perpendicular to the roof ridge. When the roof slope is greater than 15% or the roof is subject to vibration, the asphalt waterproofing membrane should be laid vertically on the roof ridge. Leakage prevention measures at joints. If the paving direction and lap direction of the waterproofing membrane are not correct, the high polymer modified bitumen waterproofing membrane and the synthetic polymer waterproofing membrane can be laid in parallel or perpendicular to the roof ridge. Avoid excessive tension and wrinkles when laying the coiled material. The base layer and the coiled material should be fully vented. After venting to both sides of the transverse direction, use a roller to flatten and stick it. The lap width and paving of the coiled material should be straight, and at the same time, the construction should be strictly in accordance with the elastic markings of the grassroots. Protect the waterproof layer when laying the insulation layer. Waterproofing is an important project of house construction. The quality of the project is related to the service life of the building, and it will directly affect the normal progress of people's production activities and life.
