Nano tech

  1. 1. What is Nano Technology?
  2. 2. CONCRETE PAINTING GLASS WOOD & STONE STEEL
  3. 3. CONCRETE Concrete is a mixture of cement, sand(fine aggregate), coarse aggregate and water. As concrete is most usable material in construction industry it’s been require to improve its quality. Nanotechnology can modify the molecular structure of concrete material to improve the material properties.
  4. 4. IN CONCRETE NANO PARTICLES MAINLY USED ARE:-- NANO SILICA & CARBON - NANOTUBE
  5. 5. CARBON NANOTUBES Carbon nanotubes are a form of carbon that was first discovered in 1952 in Russia (and mostly ignored) and then re-discovered in the 1990’s in Japan. They are cylindrical in shape, as shown in figure below, and their name comes from their nanometre diameter. They can be several millimetres in length and can have one “layer” or wall (single walled nanotube) or more than one wall (multi walled nanotube). The Production cost of nanotubes is high and the price ranges from 20€ to 1000€ per gram depending on quality . It is being used to strengthen and monitor concrete. NANO SILICA NANO SILICAADDITION TO CEMENT BASE MATERIALS CAN CONTROL THE DEGRADATION OF THE FUNDEMENTAL C-S- H(CALICIUM-SILICATE- HYBRATE)REACTION OF CONCRETE CAUSE BY CALICIUM LEACHING IN WATER AS WELL AS BLOCK WATER PENETRATION AND THEREFORE LEADS TO IMPROVEMENTS IN DURABLITY.
  6. 6. NANO IN PAINTINGS • NANO TECHNOLOGY IS BEING APPLIED TO PAINTS AND INSULATING PROPERTIES,PRODUCED BY THE ADDITION OF NANO-SIZE CELLS ,PORES AND PARTICLES ,GIVING VERY LIMITED PATH FOR TURMAL CONDUCTION ARE CURRENTLY AVAILABLE. • THIS TYPE OF PAINT IS USED AT PRESENT FOR CORROSION PROTECTION UNDER INSOLATION SINCE IT IS HYDROFOBIC AND REPLES WATER.
  7. 7. • This isolation paint can be applicable to steel, aluminum and other different metal surfaces. • This application procures perfect adherence on steel, aluminum, PVC, fiberglass, wood, concrete, plastic and much more surfaces. • You can clean easily. You just need water and soap. • Optionally can be painted.(Other colors) • High heat range between -40 °C and 240 °C • Least 10% energy saving.
  8. 8. Physical appearance of this paint is like a glass. It provides heat and corrosion isolation. There is no space in materials. So it is durable to external factors. Because of configuration of paint, oxygen doesn’t affect to internal structure. By this way we protect our materials from corrosion.
  9. 9. NANO TECHNOLOGY GLASSES TIO2 IS USED IN NANO PARTICAL FORM TO COAT GLASSING SINCE IT HAS STERILIZING AND ANTI- FOULING PROPERTIES . FIRE PROTECTIVE GLASS IS ANOTHER APPLICATION OF NANOTECHNOLOGY IN WHICH CLEAR IN TUMESCENT LAYER SANWICHED BETWEEN GLASS PANEL ‘S (AN INTER LAYER ) FORMED OF FUMED SILICA NANO PARTICLES WHICH INTURNS INTO A REGID A OPAQUE FIRE SHEILD WHEN HEATED .
  10. 10. NANOTECHNOLOGY IN FIRE PROTECTION • NANO CEMENT HAS THE POTENTIAL TO CREATE A NEW PARADIGM IN THIS AREA CAN BE USED AS TOUGH,DURABLE HIGH TEMPARATURE COATING THIS IS ACHIVED BY MIXING CNT’S WHICH CEMENT MATERIAL TO FABRICATE FIBER COMPOSITES WHICH RESULTS OUTSTANDING PERFORMANCES . • POLY PROPOLINE ALSO ARE BEING CONSIDER AS THE METAL OF INCREASING FIRE RESISTANCE AND THIS IS CHEAPER OPTION THAN CONVENTIONAL
  11. 11. NANOTECHNOLOGY IN WOOD AND STONE • This nanotechnologic product in wood and stone has several advantages. • There is a transparent layer on the wood, we don’t realize it. • For saving our materials from oil and dirt
  12. 12. ADVANTAGE • It doesn’t include silicon, oil and beeswax. • It can breath. • Antibacterial. • It is strong against acid rain and salt water. • It has a long life. • Protection from algae. • Easy application.
  13. 13. NANOTECHNOLOGY IN STEEL • American Iron and Steel Institute and the U.S. Navy started to develop new, low carbon, high performance steel (HPS) for bridges in 1992. • The new steel was developed with higher corrosion-resistance and weld ability by incorporating copper nanoparticles from at the steel grain boundaries. • Sandvik NanoflexTM is new stainless steel with ultra-high strength, good formability, and a good surface finish developed by Sandvik Nanoflex Materials Technology. • Due to its high performance, Sandvik NanoflexTM is suitable for application which requires lightweight and rigid designs. • Its good corrosion and wear resistance can keep life-cycle costs low.
  14. 14. Attractive or wear resistant surfaces can be achieved by various treatments. Compared with the conventional steel, it has a fundamentally different microstructure- a laminated lath structure resembling “plywood”. The MMFX2 steel could be an alternative because it has the similar corrosion resistance to that of stainless steel, but at a much lower cost (MMFX Steel Corp.).
