Nano coating made of rice husk

On May 16, at the New World Saigon Hotel, Ho Chi Minh City, chemistry professor Nguyen Thi Hoe, chairman of Kova Paint Group, published the results of her latest research on four types of nanotech Made from husk: fireproof, anti-fire, anti-bacterial and anti-rust paint.

This unique research has attracted the attention of more than 250 delegates who are scientists, university lecturers, business leaders at home and abroad; Especially corporations, companies from USA, Germany, Switzerland, Singapore, Malaysia ...

The main materials used to make these nanoparticles are silica nanoparticles separated from rice husks, which are hundreds of times larger than rice husk, used in many areas such as paints, waterproofing, cosmetics, pharmaceuticals, calculate ...

This paint is used for bulletproof jerseys to increase the ability to bump bullets several times and help reduce the weight of the shirt. The rice husks used in rice husks have been tested in Cambodia with the support of the military.

As a result, the pistol bullet does not penetrate 6 layers of bulletproof paint, at 2 meters, while the normal bulletproof jacket has between 20 and 40 layers of fabric, resulting in heavy weight.

Associate Prof. Dr. Nguyen Thi Hoe said that the patent will be registered in the US and hope to receive US license to transfer technology to companies producing bulletproof shirts in the world.

In addition, in his research program, Associate Professor Dr. Nguyen Thi Hoe also focuses on fire retardant materials with the main surface is concrete, wood, steel.

This product protects concrete, steel and wood surfaces in buildings in the heat of up to 1,000 degrees Celsius of fire in 2 to 6 hours.

Antimicrobial paints are of medical concern. This coating incorporates silver nanoparticles and special organic compounds that provide the ability to kill up to 99% of the bacteria on the surface. The bactericidal properties of the product have been certified in Singapore and the product has already been sold in the country.

Finally, the anti-rust paint, according to the introduction of Associate Professor Nguyen Thi Hoe, special features of this paint can be painted for the underwater works, 10 years also stainless.
