A few words about gypsum plaster
Gypsum is a natural material, completely harmless to human health. Plaster based on gypsum is a porous mixture, it regulates humidity well, improves sound and heat insulation, creates natural ventilation in the room. In addition, it is much more economical than other plasters, because most often it does not need shpatlevat( to prepare the surface for painting).
Gypsum plaster is used where there are high requirements for wall finishing( residential buildings, offices, apartments, exhibition halls, luxury business centers).Its use makes it possible to create a perfectly smooth surface of better quality. After drying, it does not need additional processing and is ready for further decorative finishing( wallpapering, painting).
Gypsum machine plaster is a non-shrink material, which excludes the formation of cracks. In addition, it provides excellent adhesion to finishing materials. Specific gravity of such plaster is 2 times less than the weight of cement compositions, so it is used without problems for leveling ceilings. Apply to the surface can be a one-time thick layer.
Advantages of mechanized plastering
Machine wall plaster significantly differs from mechanical plastering and has a number of advantages. We list some of them.
- The issue of material storage, as well as costs for unloading and distribution at the construction site, is excluded.
- Provides high performance with less labor.
- The work execution time is shortened.
- In the process of performing the work, the material is not "lost", thus the plaster mix is significantly saved.
Technology of machine plastering
The essence of the whole technology is that the machine is filled with gypsum plaster of machine application, where it is mixed with water until the required consistency is obtained. Further on a hose the mix moves to a direct place of works and is put on the processed basis. Thus, the time and labor for preparing and coating the surface with a solution are reduced.
The plastering machine can be completely different. To date, produced a huge number of models of various manufacturers. The "heart" of any apparatus is a mixing slurry pump. The equipment can work continuously with air compressors and own pumps to maintain water pressure. Preparation of the mixture is carried out with strict adherence to the mixing and dosing regime. Thus, the quality of the solution is maintained.
Dry plaster is supplied for machine application in mobile containers, which are filled in factories. Delivered containers to the construction site in special vehicles with hydraulic lifts. The silo container can be placed anywhere on the site. It takes about 4 m2.
Dry plaster material is poured into the machine through a pneumatic conveying system that is equipped with automatic control. Accordingly, the operation of the machine should not be difficult. The height and distance of the plaster feed directly depends on the capacity of the compressor. The average height can be from 50 to 90 meters, and range from 80 to 120 meters.
Warning! Whichever way of applying the plaster you use, it is advisable to always observe precautions - wear protective gloves, gauze bandage, glasses.
