Custom filler material produces excellent paint without common damage to mixing equipment


Micronized silica for paint industry produced via fine grinding jet mill

In order to produce paint of the highest possible quality, the raw materials must be tightly controlled. This includes the mineral fillers that make up to 50% of the paint. Filler materials like calcium carbonate, talc, kaolin and silica largely govern paint properties like UV resistance, weatherability, abrasion resistance and sheen. Modern exterior latex paints typically use silica as a filler material, however it is particularly abrasive to paint mixing equipment and causes expensive wear damage. This study by Samayamutthirian Palaniandy, Khairun Azizi Mohd Azizli, Ee Xun Hong, Syed Fuad Saiyid Hashim and Hashim Hussin from Universiti Sains Malaysia looks at controlling particle size and shape of silica paint filler to enhance the properties of paint while minimising damage to mixing equipment.

The researchers found that fine grinding of silica in a jet mill with controlled operational parameters produced high quality silica for the paint industry with beneficial morphological attributes such as particle size distribution, particle shape and surface texture. The filler that they prepared was also advantageous in that sharp edges of the grains of silica were removed in the milling process. This results in a high quality filler that is far less damaging to mixing equipment which would in turn prolong the life of expensive equipment, reducing costs as well as the likelihood of contamination from wear particles.

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
