Plaster as a widely used building material, due to features such as low price, ease of use and potential, have always been of interest. However, plaster also has disadvantages, including low mechanical resistance, high water absorption and cracking. For this reason, the use of additives to improve gypsum properties, especially its strength, is of great importance. One of the new approaches in this regard is the use of nanotechnology and the addition of nano -fluids to the plaster.
Nanotechnology waterproof solution uses the coating layer that creates on the surface of the product causes insulation and lack of moisture to synthetic stone and other building materials such as stone and brick. This product is solvent in the water and is applicable to brushes and pubs or flooded methods. After 24 hours the product is dried and consumed.
Nano -fluids are suspensions in which solid particles are spread in a base fluid (such as water, oil or polymer) in the nano -dimensions (less than 100 nm). These nano particles can be made of metals, metal oxides, carbon or other materials.
Why is nano -fluid used to enhance gypsum?
use nano fluids in plaster for the following reasons: Increased strength: Nanotechnology due to its small size and high surface, can effectively spread the plaster structure and increase adhesion between plaster particles and thus increase its mechanical strength. Reduce water absorption: Nanotechnology can fill the gaps in the plaster structure and prevent water from penetrating into the gypsum. This reduces the absorption of water and increases the durability of the plaster against moisture. Improvement of thermal properties: Some nanotechnology can improve the thermal properties of gypsum and increase its resistance to heat. Increased Crack Resistance: Adding nanoparticles can reduce the stresses created in the plaster structure and thus prevent it from cracking.
Nano Fluids used in plaster
Different types of nano -fluids are used to enhance gypsum, including the following: Silicone oxide oxide nanoparticles (SiO2): These particles are widely used in gypsum enhancement due to their high strength and reasonable price. Aluminum oxide nanoparticles (Al2O3): These particles can also improve plaster properties well due to their high chemical strength and stability. Titanium dioxide nanoparticles (TiO2): These particles, in addition to enhancing strength, can also plaster antimicrobial properties. Carbon nanotubes (CNT): These structures can significantly increase plaster strength due to their high mechanical properties.
method of using nano -fluid in plaster
Nano Fluids can be added to the plaster in different ways: Direct mixing: nano fluid can be mixed directly with the water used to make plaster. Add to plaster powder: nano -fluid can be added to the gypsum powder and then mixed with water. Pre -use of plaster mixtures: In this method, nano fluid is added to the plaster powder in the factory and is ready to be provided to the consumer.
The advantages of waterproof plaster formulation
The output product of waterproof plaster formulation can be placed directly on the surfaces and prevents water penetration. But at the same time, it allows the steam or moisture trapped in the plaster. Waterproof plaster formulation has no harmful or flammable substances is environmentally friendly. Waterproof concrete formulation is also available in the top formulation set. One of the advantages that this formulation gives to the final product is: Washable High compressive and bending resistance Anti -crack and anti -scratch Easy and refreshing performance
The use of nanoparticles as a strengthening in plaster is a new and effective way to improve the properties of these building materials. This method can help increase strength, reduce water absorption, improve thermal properties, and increase resistance to gypsum cracking. Given the increasing advances in nanotechnology, we are expected to see a wider use of nanotechnology in the building industry in the future.
