According to foreign media reports, a system called molecular solar thermal (MOST) appeared a few years ago, which can store solar energy in a liquid medium and then release it in the form of thermal energy. Now, this technology has been applied to a transparent film, and this film can be used inside the windows of energy-efficient buildings.
It is reported that Chalmers University from Sweden has developed this MOST film, which contains a norbornadiene-quadricyclane molecule. This makes the transparent polymer film appear orange-yellow when not directly exposed to sunlight.
However, once the sun rises in the morning, when the sun shines on this material, most of the solar energy is absorbed by the molecules. More specifically, this molecule captures some photons to make it isomerized, which means that it temporarily becomes another molecule-with identical atoms but arranged differently.
As a result, the film not only becomes completely colorless, but also prevents most of the solar energy from entering the room. Therefore, the interior of the building is cooler, which can reduce the need to operate the air conditioner.
At night, when the sun's rays disappear, the molecule will return to its previous form, and then the stored energy will be released into the room in the form of heat energy, which can reduce the need for the building heating system. This process can last up to 8 hours.
Scientists are now working to reduce the price of this molecule and increase its concentration in the film. It is believed that these goals may be achieved in a relatively short period of time, and it will soon have a commercial window modification product.
It is reported that this research is led by Professor Kasper Moth-Poulsen, and relevant research reports have been published in "Advanced Science".
Superabrasives come in the form of grinding wheels and are used when the material being processed is either too hard or too delicate for regular abrasives.
Industrial diamonds are one of the most common materials used to create the grinding material. Contrary to popular belief, diamonds are not as rare as marketing campaigns will tell you.
After diamonds,cubic boron nitride is the second more durable material for cutting. This is followed by polycrystalline.
The most obvious advantage is that these Grinding Wheels are extremely hard and durable. This allows them to give better performance and greater longevity over regular abrasives.
When your wheel lasts longer you will see reduced costs for fixtures and tooling. This opens up your budget up to investing in more machines.
You will notice that the wear and cuts on your materials will be even. Because the abrasiveness of the wheel is so strong, it doesn`t develop uneven worn away spots as quickly as regular abrasive wheels.
So the output from your production will be consistent. So your manufacturing efforts will produce reliable and consistent results.
It can be tough to justify the upfront increased costs of superabrasive wheels. But the durability and quality of their production output make them well worth it.
But you`ll quickly realize that your productivity has increased by using superabrasives. You will have more parts processed per wheel and fewer wheel changes.
Kemei produces both conventional grinding wheel and super abrasive grinding wheels, such as white aluminum grinding wheel, pink wheel ,green silicon wheel, diamond grinding wheel and CBN grinding wheels.
