The difference between elastomer waterproof membranes is also divided into 1 thickness, 2 thicknesses, 3 thicknesses, and 4 thicknesses. The weight of a medium 3 thickness membrane is about 85 kg, and the others are reduced by 10 kg each time. Asphalt coil products, transportation can only be loaded vertically, one roll next to one roll, and it will be flattened when loaded flat. The performance advantages of closed-cell foam board. The independent bubble structure has low density, high recovery rate, and independent bubble structure. Good anti-permeability and low water absorption on the surface, replacing traditional three-oil four-felt, asphalt wood fir board, etc.
2. The construction is safe, does not pollute the environment, the construction is simple and clean, and it is easy to achieve civilized construction on site. In addition to the main material, the surface material polyethylene film also has good water resistance and high strength (polyethylene polypropylene film is waterproof by this film), so the waterproof has double security. 3, no adhesive, no need to heat and bake to melt, just tear off the isolation layer, then it can be firmly bonded on the layer. The construction of self-adhesive waterproof membrane is convenient and fast.

The difference between elastomer waterproofing membranes must be protected so as not to affect the waterproof effect. Pave a 300mm300mm expanded perlite insulation block on the waterproof layer, and then add a 3cm thick cement mortar protective layer on top of it. The layer is covered with steel wire mesh, the protective layer is set with split seams, and the seams are filled with sealing materials. Protect the waterproof layer well. Precautions. In order to block the influence of water vapor from the room and cause the roof waterproof layer to bulge, the general structure often adopts an exhaust duct in the roof insulation layer and a vapor barrier layer on it (such as one oil paper or two felts). Oil, or one cloth and two glues, etc.) to block the upward penetration of water vapor. After the roofing waterproof coiled material protection waterproofing coiled material paving is completed.
There are big differences between the quality and taste of domestic construction waterproofing enterprises and these developed countries. These differences are not only reflected in the advanced and backward technical levels, but in the system, mechanism, concept, quality and other aspects. Product development. Chinese enterprises. It is not well understood that enterprises are the main body of technological innovation. Many enterprises have weak R&D capacity building, poor R&D conditions, and basically no independent innovation projects. The investment environment and human resources of enterprises are insufficient, and the development of products often relies on imitating and following the trend.
All types of water-stop steel plates are equipped with formal inspection reports and certificates. It is made of Q235 material, which has high hardness and will not be deformed by external force during transportation. It is 4 meters long for easy transportation. The delivery speed is fast, the manufacturer produces direct delivery, and the price is lower than most middlemen in the market. The conventional models can be shipped on the same day, with low freight and fast delivery. The thickness difference of non-standard steel plate is only, which is the rank of relatively small difference in steel plate thickness on the market. Our company has a complete range of products. Jointly organized by Suzhou Waterproof Research Institute of China Building Materials Research Institute and Qingdao University of Science and Technology. At the seminar, China Railway Research Institute, China Academy of Construction Sciences, Beijing Urban Construction Design and Development Group Co., Ltd., Qingdao Municipal Design Institute, Qingdao University of Science and Technology, Qingdao Metro Group, Soprema, Sika Senai, Xinda Luxin, etc. Experts, scholars and related technicians from scientific research institutions, universities, construction units, design units, and material production units conducted in-depth discussions on the key factors affecting the quality of polymer waterproofing membrane products and projects. Chao Chao, director of the Suzhou Waterproof Research Institute of China National Building Material Research Institute, said at the recent 3rd Polymer Waterproof Coil Industry Development Seminar. The 3rd Polymer Waterproof Coiled Material Industry Development Seminar was organized by the "China Building Waterproofing" agency.
Especially remove the cement mortar and other attachments on the drain outlet, chimney, and pipe wall. The male and female corners are made of cement mortar to form arc corners, with a small radius of 50mm for female corners and 20mm for male corners. If there is clear water on the base surface, it can be constructed by sweeping it away. Configure cement paste. According to cement: water = 2:1 (weight ratio). First pour the water into the prepared mixing bucket according to the proportion, then put the cement in the water, soak for 15-20 minutes and fully soak, pour out the excess water on the surface of the bucket, and then add 5% of the amount of cement. 8% polymer construction glue (water retention agent), stir with an electric mixer, and the stirring time is more than 5 minutes.
On the contrary, bad SBS coils are not black glossy, they have insoluble particles in cross section, and the coils are rough. It smells, high-quality is basically not thick. Touch: SBS roll material is relatively soft, elastic, and has good viscosity. It is tightly combined with the tire base and shows excellent low temperature resistance. If the quality is poor, it will easily break and peel off the asphalt, without elasticity. Kneading the surface of the coiled material: take a small piece and check whether it is organic oil after kneading. A large amount of inferior waste is added with a large amount of waste oil and other solvents to make it look soft. When the oil evaporates, the service life is within 3 months.
