Youth Union of the Institute of Building Materials participated in the Viet Creation Program

Receiving an invitation from the Organizing Committee of the Program “Vietnamese Creation”, broadcast at 9am every Sunday on VTV3, the Youth Union of the Institute of Building Materials (Building Materials) has established three teams to participate in the chapter. submitted and recorded on July 17-18, 2012 at the Cultural House of Thanh Xuan District – Hanoi with three topics:

Topic 1: Technology solutions that increase the durability and efficiency of fragile materials. Joining the playing team of the Institute of Building Materials is the team from Hanoi University of Technology.

The idea of ​​the Institute of Construction Materials team is to manufacture metallic glass with the following properties: Transparent, high hardness and plastic deformation like metal instead of fracture deformation like normal glass.

The theoretical basis of the metal-glass fabrication method is that any molten liquid has the ability to form glass if cooled at a sufficiently fast rate. Metal mixture is melted at high temperature, then metal alloys including Titanium (Ti), Zirconium (Zr), Niobium (Nb), copper (Cu) and Beryllium (Be) are melted and kept. At temperatures of 800 ° C and 900 ° C, the “branching crystals” of Ti, Zr and Nb begin to grow to large sizes. And during growth, Be and Cu do not play a role in making “branching crystals”.

Ending the game on this topic, the Institute of Building Materials team spent 6,100 points, ranked second.

The second topic: Methods to effectively treat industrial emissions, protect the environment. Joining the team at the Institute of Building Materials is the team from Urenco10 Company.

The idea of ​​the team of the Institute of Construction Materials is “Application of limestone to treat SO2 in the smoke”. It is using a pressure pump system to pump the solution containing the adsorbent directly into the adsorption tower or exhaust smoke path.

The process of mass transfer occurs in the device due to heat and steam.

– The solution is circulated until all CaCO3 converts to CaSO4.

– Automatically withdraw the converted solution into CaSO4 and add new solution by automatic density-based dosing system.

It is reasonable to use limestone for SO2 treatment in flue gas. For specific businesses, different methods of doing this can be applied. Institute of Construction Materials is ready to consult and cooperate with businesses to implement and deploy.

Ending the game on this topic, the Institute of Building Materials team finished first with 5,550 points.

The third topic: New construction materials production technologies to limit and replace toxic and polluting construction materials. Joining the playing team of the Institute of Building Materials is the team from Hanoi Architectural University.

The team of the Institute of Construction Materials presented an innovative idea with the title: “Manufacturing environmentally friendly anti-corrosion paint”.

Currently, to protect steel structures from corrosion, commonly used coating materials are organic solvent paints such as Alkyd paint, Epoxy paint, PolyUrethan paint, …

The basic characteristics of these organic compound solvent paints are: Not environmentally friendly because the solvents are volatile organic compounds, not durable at high temperatures, and expensive.

To overcome the above disadvantages of this organic solvent paint, the paint that does not use organic solvents is being studied, which is the water-solvent-rich zinc silicate coating system, which has the following advantages:

– Is an environmentally friendly paint due to the use of water solvents.

Production materials are available domestically.

– Easy to apply.

– Has good adhesion to metal substrates.

– High thermal stability.

– Creating an inert film against harsh environments: seawater, chemical environment.

– Simple production technology line.

– Reasonable product price.

Ending the game on this topic, the Institute of Building Materials team finished first with 5,900 points.
