Product characteristics
Crack resistance / fire prevention / short construction period / indoor environment health / low maintenance cost
1. Fine powder, strong adhesion, small drying shrinkage, strong adhesion with the substrate, no hollowing, no cracking.
2. It has good fireproof performance. A large amount of crystal water is released under the action of high temperature to form steam. Increase the flame retardant time.
3. At the initial stage, it has good water retention, good workability, simple and convenient construction, and can also be mechanized spraying.
4. It is safe, non-toxic and non radioactive, which is worthy of the name of green building materials.
5. The coating rate is good, the theoretical dosage of 10 mm thick per square meter is as follows: light manual wipe 7 kg - machine spray 10 kg, compared with the traditional
More than 1 times of cement mortar is an ideal material for plastering.
The main performance characteristics of light gypsum plaster are as follows
European mature formula, recycling economy, selected raw materials, accurate calcination ability, high-grade manufacturing gypsum content, high cohesion, fast construction, pH value close to neutral light, high coating rate, saving freight, fully matching with the performance of new lightweight block, the finished surface is flat and vertical, repairable planer switch slot repair excellent material, excellent plastering material for concrete ceiling Cracking green low carbon, will breathe environmental protection, energy saving, circular economy, green building green environmental protection, no benzene, no formaldehyde, no radioactivity.
respiratory function
Adjustable indoor air humidity. When the room is dry, it can release moisture. When the indoor humidity is high, it can absorb the moisture and automatically adjust the humidity, so that people will not feel cold and irritable in the house, and greatly improve the quality of the house.
Safety and fire prevention
The final hydration product of gypsum products is calcium sulfate dihydrate. In case of fire, the temperature can only rise when two crystal water are decomposed completely. A large amount of water vapor fog generated during the decomposition process also blocks the spread of flame.
Good adhesion and high strength
Plastering gypsum has strong adhesive force, which overcomes the problems of cracking and hollowing after the traditional plastering mortar is covered. The plastered wall surface is more delicate, smooth, flat, non shrinking, odorless and crack free than that of the traditional plastering mortar.
Convenient construction
The construction process is simple and fast, and it can be used for mechanized plastering construction. Especially in the process of ceiling plastering, it is not easy to drop ash, save materials and create a better construction environment.
Fast setting and short construction period
The plastering gypsum plaster layer has the advantages of fast setting and hardening, short curing period, and the whole hardening agent strength reaching the standard can be completed in 1-3 days. Compared with the traditional plastering mortar, the construction period can be shortened by about 5-7 days, which greatly improves the work efficiency and speeds up the project progress.
Good for winter construction
Plastering gypsum has the characteristics of early strength and quick setting, and the construction is not limited by seasons, especially in winter when the temperature is above 5 ℃. The hydration speed is not obviously slowed down due to low temperature. As long as the mixing water does not freeze, it can be plastered. It is a good material for indoor plastering in winter.
Thermal insulation
Plaster hardening body is a porous material, the thermal conductivity is 30% of concrete products and 45% of clay brick under the same conditions
