Every fogy day, everyone is always armed with masks and scarves, and my heart is still not practical. Doesn't that have a "protective shield"? Recently, researchers from Jiangsu Normal University have developed a new set of equipment: "Smog and haze protective clothing."
This is the "fog and haze protective clothing" developed by researchers at Jiangsu Normal University. From the appearance point of view, this "equipment" is divided into hats and jackets, lightweight and easy to carry, but there are many inside the mystery. In this set of equipment, there are specialized masks, and a mask specially designed for the adsorption of smog particles is developed based on the adsorption properties of PM2.5. The carbon membrane in the mask has tiny pores and the air can freely come in and out, so even if wearing a mask, it will not feel boring. At the same time, in order to increase the humidity and comfort of the internal environment, the flood prevention cap is also designed to add a waterproof pocket.
In another part of the protective clothing: anti-fog jacket, there is a humidity sensor for PM2.5, and the fan can adjust the humidity inside the clothing, the temperature of the air permeability, so you can connect with the solar silicon power supply automatically.
The members of the research group also independently developed an APP software that can help analyze the current state of the body by entering the relevant haze values ​​and other data. At present, both the flood prevention cap and the flood prevention jacket have obtained national patents, and the patent right of the flood prevention cap has been successfully transferred by 5 million. Then the relevant manufacturers will carry out mass production.
An ideal material in high temperature applications, which has high operating temperature up to 550°C and above, with excellent corrosion resistance. They can become partially demagnetized if they come in contact with other ferrous materials, special care is required during handling and storing.
Usually cast and grinded during production, they are available in various grades depending on its application. Others such as sintered Alnico have lower magnetic properties but offer higher mechanical characteristics
Casting Alnico
With low temperature coefficient, higg temperature resistant, resistant to moisture, not easy oxidation and working stability well.
Main application in automobile parts, instrumentation, electroacoustics, motor, teaching and aerospace military, etc
