- Therefore, rainy days should not be construction, to wait until the sun will dry the water before construction. The roof of a large area of leakage or a number of water leakage points, the first by the professionals to check whether the cracks, according to the previous program to deal with the cracks in the roof covered with waterproofing membrane, to enhance the waterproof effect, you can also shop On the insulation board, because the height of the insulation board in 20 cm or more, to achieve the protection of waterproof layer and thermal insulation of the double effect. Do not want to use the insulation board of the family, you can consider the use of steel mesh concrete, leak-proof effect is also very good. Wall cracks appear seepage, under normal circumstances the professional construction team will use the basket, by the maintenance staff in the external wall construction.

- Q:What are the key points and contents of the quality control of waterproof material?
- 2, ordinary two-component polyurethane: A material is similar to the appearance of edible oil translucent yellowish curing agent from polyether and isocyanic acid by polycondensation of polyurethane prepolymer (about 20,000 yuan / t), B material For the plasticizer, coagulant, fillers and other components of the black liquid (about 3900 yuan / t), after mixing the polyurethane coating is also black. But also because of A, B material of the huge spread so often the following two kinds of fraud: ① with a very cheap black oil (priced at only about 1,200 yuan / t), diluted with xylene after thin coating twice. Cold oil is not easy to dry after the coating, after each coating must be drying a few days, in the winter with roasted, and then do not sprinkle dry powder cement, so a long time paint are dry. ② is often used to expand the proportion of A, B components such as 1: 4-6 (usually 1: 2), but also in the polyurethane mixing process by adding cement powder as a filler, if the stirring is not added xylene diluted Agents and other methods of fraud.
- Q:Roof membrane waterproof construction process, what should be noted that?
- Three do
1 to do concrete or mortar ratio is accurate
2 to do the surface of the second calendering
3 to be fully maintained
- Q:What is the car material so that the car can be waterproof, in the rain will not leak in?
- C. metal technology and other: metal technology refers to the aluminum plate and other metal plate through the machine to suppress the concavity and convex surface, and then made of metal paint color, and finally after grinding, drawing and other production of the car stickers (car standard); Area can not be too large, can only be used for a small range of iconic car stickers.
- Q:What should you pay attention to before the construction of the basement waterproofing membrane?
- 3, painting the bottom line: for the reasonable arrangement of the daily pavement workload, must first on the basis of the program according to set the program to draw a good dividing line, the entire track and field into pieces, and then press the block by pavement. In order to ensure smooth drainage and less joints and other requirements, the use of the first outer ring after the construction process.
- Q:Roof for the insulation, Master roof, using two waterproof construction program
- Fourth, the finished product protection
1, has been laid the membrane waterproof layer, should be taken to protect the facilities, is strictly prohibited in the waterproof layer on the construction operations and transportation, and should be timely to do the protective layer of the waterproof layer.
2, through the roof, wall waterproof layer at the pipeline, construction and after the completion of damage shall not damage.
3, deformation joints, water, etc., before the construction of waterproof layer, should be temporary closure, waterproof layer is completed, should be cleared to ensure that the tube, sewn smooth, to meet the use of function.
4, roof construction shall not pollute the walls, cornices and other finished products.
- Q:What is PE waterproof cloth and PVC tarpaulin
- The characteristics and performance index of waterproof cloth products
1. Tensile strength index: warp strength ≥ 2100N / 5CM, zonal strength ≥ 1600N / 5CM; 2. No leakage of water, water pressure ≥ 2000MM water column; 3. Low temperature, cold temperature -20 ℃; 4 Can be mildew, mildew experiment for the first level.
1. Can be used car, train, ship cargo tarpaulin;
2. It can be used for the open storage of the harbor airport at the station terminal harbor;
