Waterproofing of modern buildings
Modern building waterproofing started from the use of asphalt as a waterproofing treatment for construction projects. The utilization of asphalt has gone through the stages of natural asphalt, petroleum asphalt, and polymer-modified asphalt.
Waterproofing of modern buildings
Although our waterproof technology and level have made progress, it still lags behind the world's advanced technology level. For example, the currently popular polymer coils have been used abroad for many years. And no matter how it is done, it is difficult for domestic high imitations to outperform imported hard currency. This is related to price, but also to the spirit of craftsmen. There is no way that the gap is still impressive. There are only a few manufacturers of waterproof materials in the emerging passive ultra-low energy buildings. Although we have not stopped in the footsteps of embracing the world, it still takes a lot of time. Then there is the "bringing doctrine" of "learning from the barbarians to control the barbarians".
After the reform and opening up, our rapid development has become a veritable infrastructure maniac in the world, which has also promoted the progress of construction engineering waterproofing technology.
Looking at the world, we have seen a lot of waterproof materials and market opportunities, produced a variety of waterproof materials, and formed the waterproof spring of "a hundred flowers bloom and a hundred schools of thought contend".
In the 1980s and 1990s, the modified asphalt waterproofing membrane production line was introduced from Germany, the United States, Italy, Spain and other countries as a whole, and the continuous vulcanized EPDM production line was introduced from Japan. Breaking the situation of "three felts and four oils" dominating the world in the linoleum era. Many state-owned enterprises and today's waterproof overlords have launched import production lines at this time, but the big waves wash away the sand, and the fittest survive. In the middle of the day.
From 1981 to 1985, we successively developed PVC glue, plastic ointment, rubber-modified asphalt waterproof coating, polyurethane waterproof coating, EPDM waterproof membrane, PVC waterproof membrane, rubber-modified asphalt waterproof membrane materials, etc. to enrich the category of waterproof materials.
