What is an air knife?
The air knife is cleaning, drying and cooling used in production and other processes. By creating a high intensity, a balanced leaf of laminar air flow along the entire length of the object, the air knife can clean, dry or cold components, sites and conveyors. The laminar air flow refers to the uniform airflow of the layer, which is not mixed with other layers in the area. Air knives come in two types, linear and circular, and can be made of aluminum, steel or plastic. However, the thermal lamp dryer did not completely remove the residues of the fixed phase and took more time and space. On the other hand, the air knife takes less time, takes less space and mainly dries the components.
But the drying of the needle one of the different functions that the air knife performs. The field of production uses of air knives is confused. For cleaning, drying and cooling any type of surface from cans and bottles to fabrics and circuit boards, air knives are usually used.
In Coverying Systems Air knives, they are used on continuously produced works or products. For example, in the cement industry, air knives can be used to remove dust and gravel from the conveyor. In the case of high -end products, such as plates with circuits that pass through many chemical baths during production, air knives accelerate the production process by drying boards with circuits after each chemical bath. Extruze rubber used in the manufacture of seals for doors and windows of the car requires immersion in potassium nitrate with hot salt to shine. The air knife can be used to blow off excess salt to restore gloss.
Anvzuch knife can also be used to remove viscous contaminants from the surface. Cutting oil used in the production of threaded metal bars can be blown with an air knife ..
In addition to regular industrial use, air knives have further use. Pushed two sheets of paper or oceLi and prevention of friction between the layers acting as an air curtain to avoid mixing two types of air, and the soil blowing from the roots for control are some of the other use of the air knife. Air knives are available in different sizes. Three tracks (0.91 meters) A long air unit can stand anywhere between $ 500 and $ 3000 in the US (USD) depending on functionality.
