What is foam insulation
- Phenolic foam
Phenolic foam is a polymer organic rigid aluminum foil foam products, is made of thermosetting phenolic resin foam, it has a light, fire, case of fire does not burn, smoke, non-toxic, no dripping, the use of temperature Wai wide -196 ~ +200 ℃) is not shrinkage and no embrittlement in low temperature environment. It is an ideal insulation material for HVAC refrigeration. Because of the high porosity of phenolic foam, the thermal conductivity is low, the heat insulation performance is good, and it has water resistance and Water vapor permeability, is the ideal insulation energy-saving materials. As the phenolic has a benzene ring structure, so the size is stable, the rate of change <1%. And the chemical composition of stability, anti-corrosion anti-aging, especially organic solvents, strong acid, weak alkali corrosion. In the production process without foaming fluoride to do in line with international environmental standards, and its molecular structure contains hydrogen, oxygen, carbon elements, pyrolysis, the overflow of gas non-toxic, tasteless, harmless to the human body, the environment, In line with national green environmental requirements. Therefore, the phenolic super-composite board is the best fire, adiabatic, energy saving, beautiful green green insulation materials.s
What is the specific waterproofing of the bathroom?
- Polyurethane waterproof coating general approach is as follows: 1, the ground to the direction of the ground to find slope, cement mortar or bean concrete can be, but the surface to be flat. Near the door slope is small, the gap near the slope, according to the specific situation to master. 2, the pipeline to wear the floor of the root, to strengthen the waterproof. Tube root construction seal seal, cement smoothing foot protection, brush waterproof coating when the paste from the wire to strengthen the layer 1 to 2 layers. The same measures around the floor drain. 3, the wall to deal with clean plain light without floating ash, small particles, wall ground junction to wipe the original angle or slope angle. Brush waterproof coating when the glass cloth to strengthen the layer 1 to 2 layers. 4, the total thickness of polyurethane waterproof coating requires more than 1.5 mm. Can not rely on the number of decisions. Root, corner reinforcement layer at the first brush, room temperature 4h dry, and then a large area of brushing, Tu scraping. There is no leakage scraping, bubbling phenomenon. Large area brushing 24h curing after brushing the next layer. 5, first brushing the facade after brushing the plane, the next brushing direction and the vertical again. The last time the film semi-curing, throwing coarse sand particles, easy to combine with the cement mortar in the future. 6, the ground waterproof layer should be painted out of the bathroom door outside the 300 wide. Waterproof surface waterproof layer should be higher than the ground 200, a shower bathroom wall waterproof layer should be higher than the ground 1800 (L8 recommended full wall waterproof).s

2. Base surface should be flat, no hollowing, from the sand, cracking and other defects. Base water content should meet the construction requirements of waterproof materials. The waterproof layer should extend from the ground to the wall, 250mm above the ground. Bathroom wall waterproof layer height of not less than 1800mm.
3. Waterproof cement mortar leveling layer and foundation with dense, no hollowing, smooth and smooth surface, no cracks, from the sand, yin and yang angle made of circular arc.
4. Coating waterproof layer brushing uniform, the thickness of the product to meet the technical requirements, the general thickness of not less than 1.5mm do not reveal the end.
5. The use of construction stubs should be along the direction of the flow of water, lap width of not less than 100mm, the use of two or more fiberglass cloth up and down when the overlap should be staggered width of one-half.
6. The surface of the coating is not blistering, does not flow, smooth without bumps, and pipe fittings, sanitary ware to the ground, floor drain, drain seams tightly rounded and tight.
The above is the content of the waterproof acceptance criteria, we hope to help. This knowledge will be used in the decoration, as long as more knowledge of these knowledge will be useful for your decoration.s

2, in the room into 10 cm deep water, at the same time to do the height of the water mark;
3,24 hours after the observation of whether the height of the water surface has changed, but also check the same location downstairs room ceiling whether the phenomenon of water seepage;
4, if there is no such phenomenon, that can be considered waterproofing construction acceptance; the other hand, if the inspection found that the phenomenon can be considered waterproof construction failed. If the acceptance of substandard, waterproofing works must be redone the whole, re-acceptance; for lightweight wall waterproofing construction acceptance, should take the water test, that is, the use of water pipes in the waterproof paint on the wall from top to bottom Intermittent spray 3 minutes, 4 hours after the other side of the wall to observe whether there will be infiltration phenomenon, if there is no penetration phenomenon can be considered waterproof wall construction acceptance.s
