A, sbs coil construction technology
SBS？ There are two construction methods for modified asphalt waterproofing membrane.
1) hot melt paving method
(1) Hot-melt paving method can reduce the construction cost of waterproof layer, save the amount of adhesive and avoid the hollowing of waterproof layer;
(2) Cement mortar leveling layer should be made at the grass-roots level, which should be solid, smooth, shiny and free from bulging. The base must be dry. The water content should be below 9%;
(3) Brush on the dry base? SBS？ The cold bottom oil of modified asphalt waterproofing membrane should be evenly coated at one time and dried for 6 hours (depending on the temperature, it is better not to stick to the feet);
(4) Straighten the coil according to the position first, and ignite the blowtorch (the distance between the blowtorch and the coil is 0.3? m？ ), heat the coil and base with a blowtorch, roll forward immediately after the surface of the coil melts, and heat evenly. Don't get involved in air and foreign matter when rolling, compact and flatten. Before the coil is cooled, use a trowel to seal the edge, and then use a blowtorch to seal the seam evenly and carefully, paying special attention to the edge and complex parts to prevent the edge from warping;
(5) The construction technology of bilateral practice is basically the same as that of single-layer practice, and the second-layer paving should be staggered by 0.3 with the first-layer coil. M or so (generally a single-story building is enough);
(6) Safety protection: During hot melt construction, the management and maintenance of gasoline storage and blowtorch should be strengthened to prevent fire and industrial accidents.
2) Cold bonding method
(1) Basic treatment and coating of basic treatment agent are the same as hot melt paving method;
(2) Brush the primer: Yes? SBS？ Adhesive rubber asphalt adhesive, neoprene adhesive, choose one. It is required that the coating should be uniform, and the dosage per square single layer should be 0.5 ~ 0.7? kg？ ;
(3) Waterproof coiled material laying process: put the coiled material in place before setting aside 10? cm？ Wide summer-planting, roll forward and roll back. The paving is required to be compact and flat, and be careful not to get involved in air and foreign bodies, and there can be no wrinkles and bulges. Joints should be completely coated with adhesive and dried for 20? Min? Then roll it hard to make it stick.
(4) Surface treatment: If it is necessary to prevent sand after the coil is pasted, it can be coated with a layer of rubber asphalt coating and sprinkled with sand or mica. During the construction (only three people are needed), each Eden will complete its own process. A, sbs coil construction technology

Although we all know that sbs coiled material, as a basic building material product, not only has a good service life, but also its stable performance and good cost performance make it stand out in the market, the final use effect of the product still needs to refer to the above-mentioned reasonable construction process operation and understand the corresponding precautions and skills in each step, so as to give full play to the maximum value of sbs coiled material in corrosion protection, waterproof and heat preservation. Interested friends may wish to refer to the above to find out.
