Elastomer bitumen waterproofing membrane code, so use waterproofing materials should be cautious. Coiled materials cannot be used for the waterproofing of toilets and baths. only the paint is suitable, and the cement-based acrylic paint is suitable for the paint, which can firmly stick the tiles on it. Because toilets and baths are not affected by the natural climate, no temperature changes, and low requirements for material elongation, secondly, the area is small, there are many Yin and Yang angles, and there are more pipes through the floor, and thirdly, tiles are placed on the waterproof layer of the wall. , Good affinity with binder. In addition, the selection of waterproof materials also needs to consider the needs of building functions.
The construction of external wall insulation works should not be taken lightly. External wall insulation construction conditions. The construction site should have electricity and water construction conditions, and maintain a clean working environment. The ambient temperature of the site and the surface temperature of the base wall during surface construction should not be lower than 5°C, and the wind should not be greater than level 5. Appropriate protective measures should be taken during winter construction. When constructing surface mortar, avoid direct sunlight. When necessary, put up sun protection cloth on the construction scaffold to cover the construction wall.

Elastomer bituminous waterproofing membrane code code Nozzle and base surface junction, after wiping the leveling layer, reserve a groove, fill in the sealing material, and then remove rust and polish around the pipe. Set within 500mm around the pipe mouth. An additional layer of waterproof, adding a glass fiber cloth to ensure that the waterproof effect is fully achieved. Large area spreads the coiled material. There are two main methods for attaching self-adhesive coils to large areas. In actual construction, the construction personnel can determine the method of attaching by themselves according to the site environment, temperature, sunshine and other conditions, but the basic exhaust and compaction , The anti-wrinkle requirements remain the same.
As for the price of waterproof membranes, not only will it be affected by types, specifications, and models, but also different brands and materials have different prices, so they cannot be generalized. So under normal circumstances, what are the prices of different materials and specifications? The price of waterproof membranes of different materials: the prices of waterproof membranes vary greatly. For example, the more commonly used polymer self-adhesive membranes are taken as an example. The 4mm thick polyurethane PE mould -25 degree polymer self-adhesive waterproof membranes are generally around 20-25 yuan/square meter.

Drill the coil and the base layer with a percussion drill at intervals of 600-900mm. The embedded plastic expansion plugs are fixed with self-tapping screws and gaskets, and then fixed with 奵00- The 50 coils are welded on a fixed point and the point is sealed at the same time. The fixed point can also be placed on the welding seam side of the lower coil, and then the fixed point is welded inside when the upper and lower coils are welded. Rewinding the coil. After all the coils have been laid and passed the water test, the receiving part can be fixed with aluminum strips (℃25mm) with nails, and sealed with sealing paste.
The Japan Housing and Urban Development Corporation aims to improve the functions of the houses it builds, and promotes the development and research of various flat roof waterproofing methods. The construction methods researched and developed by the Experimental Research Institute of the Corporation have generally undergone the following changes in the following stages since 1955. Mortar is self-waterproof (1955-1957). Concrete is self-waterproof (1958-1962). No heat insulation and exposed bitumen waterproofing (1963-197 Three felts, four oils, and gravel membranes are made on the structural layer for waterproofing, without heat insulation.
It can change the colloidal dispersion structure of asphalt and also change the dispersed components. The polymer molecules separate from each other to form a network structure, while the asphalt is filled into the network polymer compound. After cooling, the asphalt remains at that position. Artificially enhance the mobility, elasticity and plasticity of polymer molecular chains. The high-molecular polymer rubbed into the asphalt must have good compatibility with the asphalt. The high-molecular material contains a branched structure. Even if the amount of blending is small, a network-like elastic structure can be formed, which has a large range of high It is in a cohesive state, so when the temperature rises, it can have a certain mechanical strength, and when the temperature is low. It has better elasticity and plasticity after blending with polymer in asphalt. The coiled material connecting the paving plane and the elevation should be carried out from bottom to top. Heat-melt edge sealing, use a spray gun to heat the overlap of the coil to make it adhere firmly, and then paint the waterproof coil. Before waterproofing construction, ensure that the ground is clean and dry. The waterproofing membrane must be fully coated to ensure that there is no omission. It must be firmly bonded to the base layer without cracks and bubbles. The thickness of the waterproofing membrane must meet the requirements of the product. After the waterproof membrane is completely dry, perform the second waterproof painting. If the waterproof membrane is not completely dried, the second waterproof construction will greatly reduce the waterproof effect.
