The main functions of waterproof fabric are: waterproof, moisture permeable, breathable, heat insulating, windproof and warm. From the production process, the technical requirements of waterproof and breathable fabrics are much higher than those of ordinary waterproof fabrics; At the same time, from the quality point of view, waterproof and breathable fabrics also have functional characteristics that other waterproof fabrics do not have. Waterproof breathable fabric not only enhances the air tightness and water tightness of the fabric, but also has its unique moisture permeability, which can make the water vapor in the structure discharge quickly, avoid the growth of mold in the structure, keep the human body dry all the time, and perfectly solve the problems of air permeability, wind resistance, waterproof and warmth retention. It is a new type of healthy and environment-friendly fabric.
Real waterproof fabrics can withstand the osmotic pressure in humid climate for a long time and are impervious to water. For example, walking outdoors for a long time in stormy weather, kneeling or sitting on wet ground will not leak water.
Waterproof cloth construction method
The base surface of waterproof construction shall be solid, flat and smooth, and there shall be no looseness, sand, cracks, cocking, spikes, potholes and hollowing. Before construction, the surface must be smooth, firm and clean, so that the construction process is easier and the waterproof function is good.
1. Generally, if the materials are selected according to the regulations, some water will be appropriately added to the materials. But when paying attention, you must first add water to the liquid material, and then stir it. After stirring, as long as there are no particles, don't stir by hand. After painting, some colored pigments can be added to form a colored waterproof layer.
2. In the process of construction, you must choose appropriate tools to operate, from the lower part to the bottom to the middle and top.
3. For the protective layer protection work, it must be carried out about three days after the waterproof layer is completed. In order to carry out it quickly, you can brush the last surface and sprinkle clean medium and coarse sand, which is basically completed.
