Elastomer-modified bitumen waterproofing membranes are divided into polymer waterproofing materials according to the tire base, and there is a huge future for them. Qingdao University of Science and Technology is a domestic university that has conducted polymer research early. According to Qiu Guixue, a professor at Qingdao University of Science and Technology, polymer waterproof materials have high strength, good flexibility at low temperatures, large elongation, and strong adaptability, which solves the problem of cracking in traditional waterproof materials, thereby ensuring the quality of waterproofing. Corrosion resistance, aging resistance, and long service life. Generally, the durability of synthetic polymer waterproofing membranes is more than 10 years.
Scope of application. Suitable for roofing, basement, indoor, municipal engineering and reservoir, swimming pool and subway tunnel waterproofing of industrial and civil buildings. It is also suitable for waterproofing of wooden and metal structure roofs. It is especially suitable for re-waterproofing projects in facilities that require cold construction and oil depots, chemical plants, textile mills, and grain depots that are not suitable for open flames. The waterproofing of the bathroom in the house decoration is a more critical link. It is not recommended to use polypropylene coils for waterproofing. Because the bathroom is a relatively stable part of the house structure, the waterproof requirements are lower than that of the balcony and roof.
Waterproof membrane Q3y1GkXD4
Elastomer modified bitumen waterproofing membrane is divided into tire base. For further information, please contact us by phone. We will provide you with technology and product services. With the emergence of various high-rise buildings, more and more basements have appeared. Due to special reasons, the location of the basement is easy to seep water from wall to wall. The lower the basement, the more water permeable sludge, so the basement is needed. Waterproof, but the basement waterproofing method is more complicated and more difficult than the ground waterproofing method. The following describes the basement waterproofing construction plan. Rolled material waterproof layer is suitable for underground engineering under the action of corrosive medium or vibration, usually in underground water environment.
Treatment method: first cut off all the bulging parts to expose the base layer and drain the moisture. After the base layer is dry, repair it according to the construction method of the waterproof layer. The technical term for fire-roasting is called hot-melt. The material is sbs modified bitumen waterproofing membrane. The big difference between self-adhesive waterproofing membrane and SBS membrane lies in the construction. The self-adhesive waterproofing membrane belongs to cold construction and does not require hot melting. It can be bonded with the base layer only by tearing off the isolation layer to form a sealed waterproof layer.
The spot check results show that the unqualified items are low temperature flexibility, heat resistance, stickiness, peel strength, re-peel strength of self-adhesive asphalt, soluble content, composite strength, hot air aging, and tensile properties. Experts said that products with unqualified low-temperature flexibility have poor ability to withstand the deformation of the base layer during use in winter, and the materials are hard and easy to crack, thus losing the waterproof effect. The spot check found that the low-temperature flexibility of 2 batches of elastomer-modified asphalt waterproofing membranes was unqualified. When we are talking about waterproofing, we can truly achieve the goal of blocking environmental water and preventing building leakage, without worrying about it. Traditional waterproofing membranes often refer to waterproofing membranes such as petroleum tire linoleum and ointment. These waterproofing membranes are still used in rural areas in a proper number of houses. The difference between traditional waterproof membrane and new waterproof membrane. A. This kind of traditional waterproofing membrane has many defects: low stretch rate, aging resistance, poor waterproof function and other defects, so we often encounter roof waterproofing made of this kind of membrane, and we will start to do it in a few years. Repaired. It is hoped that a complete renovation will be carried out in less than ten years.
What is honeycomb. The concrete is locally crisp, there is less mortar, and there are many stones. There are gaps between the stones, forming honeycomb holes. What is an upright roof? The waterproof layer is on top of the thermal insulation layer. What is an inverted roof? The waterproof layer is under the insulation layer. What is a primary treatment agent. In order to enhance the adhesion between the waterproof material and the base layer, the paint on the base layer is pre-painted before the waterproof layer is constructed.
First, it is difficult to unwind. Except for the elastomer modified asphalt coil with low temperature flexibility up to -18℃, the second is difficult to bond. During the hot-melt construction, the hot melt adhesive on the bottom of the coil also heats the base layer, so it can be at low temperature- Work under the condition of 10℃ or higher, but the energy consumption is relatively high. Because of the limitation of uncoiling temperature, bituminous coils should be constructed under the environmental conditions of air temperature above 5℃. The high temperature environment is specified to work under 35℃, mainly considering the working conditions of construction workers. Excessive temperature can cause personal injury to workers, so high temperature environments are allowed to work under 35℃. Two problems will be encountered during low-temperature construction of polymer modified asphalt coils. At present, many waterproof membranes on the market have a little difference in weight from the weight indicated on the barrel, and consumers can weigh them on the spot when purchasing. Smell discrimination. At present, the two-component cement-based waterproofing slurry on the market is more stable than the one-component waterproofing performance. The liquid odor in the high-quality waterproofing slurry is faint. On the contrary, the inferior waterproofing membrane will have a strong and pungent odor. Check the waterproof effect. Take the polymer waterproof membrane as an example. The genuine product can be removed from the wall or floor with a knife. The rubber will not be broken when folded in half, and it is extensible.
