Waterproof material is the key point in steel structure waterproof engineering
Nowadays, steel structure buildings are used by many cities because of their better earthquake resistance and disaster resistance. In the waterproof and fireproof engineering of steel structures, a lot of paints need to be used. A wide variety of waterproof materials are spread all over the world, but there will also be many cases of leaking steel roof structures. How did this problem arise? How to eliminate these problems has become a problem studied by many engineers, but these problems have been solved Next, let's introduce a new type of roofing waterproof material.
The traditional roofing steel structure uses the old-fashioned waterproof coiled material, which is generally paper tire linoleum. When linoleum is used as a waterproof layer, construction asphalt must be used as a bond, and sand and stone should be applied. If this is used, the project is very complicated. It is three-oil two-felt or four-oil three-felt. This method is labor-intensive and the construction technology is not easy to master. Also, the environmental pollution when preparing asphalt is very large, even if it does so, There may also be water seepage, so this kind of waterproof material for roof steel structure is almost no longer used. It has been replaced by a new generation of waterproof material. The new generation of waterproof material has light weight, construction, and does not pollute the environment. Durability, beautiful colors and other properties, it is also divided into two kinds of membranes, one is a polymer waterproof membrane It is made of paper tire linoleum-rubber membrane-composite membrane modified asphalt membrane-various polymers Synthetic, there is a modified emulsified asphalt-plastic ointment-polyurethane waterproof coating-environmentally friendly synthetic polymer color waterproof material, these roofing steel structure waterproof materials have their own Advantages, different materials can be used for different occasions, these advantages are used according to different occasions, some are easy to obtain materials, some are low-cost, some are expensive but it is particularly durable and so on, when choosing materials In addition to considering the variable factors such as climate and region, the factor of the building must also be considered. For example, the place where the waterproof membrane is suitable is not suitable for waterproofing with paint, and the place where the coating is suitable is not necessarily suitable for using membrane; Use coiled material for waterproofing: wet base, poorly drained or permanently hydrated parts, uneven base and many protruding embedded bases, back water surface, and waterproofing; if the base is not suitable for paint waterproofing: wooden slope tile roof waterproofing Wait.
The problem of water leakage is not unsolvable. As long as the correct solution is found, the problem will no longer exist. The roof steel structure waterproof material will bring another new world.
