Characteristics and application of aluminum alloy air knife

Aluminum alloy air knife in the industrial field, there are a lot of blowing water, blowing dust and other applications, such as blowing dust and water on the plane of steel plate, aluminum alloy profiles, blowing water on the surface of beverage bottles, packaging cans and other bottles, blowing away impurities on the surface of the product dust, residual liquid, water on the outer packaging, and conveyor belt cleaning. In the presence of compressed air supply, the aluminum alloy air knife can best meet these applications. What are the characteristics and applications of aluminum alloy air knife?

Features and application of aluminum alloy air knife:

1. The structure adopts unique design to ensure that the air resistance is small, the air speed is uniform, and the accuracy can reach ±5%.

2. Can withstand high air speed 200m/s, high temperature 250℃, high pressure 2kGF /cm2.

3. Stainless steel 304 as the body body, extruded aluminum alloy 6061 as the blade, precision production, strong air, energy saving, practical and reliable characteristics.

4. Supporting the use of eddy current fans, centrifugal fans, flexible and convenient application.

5. The width of air outlet of air knife can be adjusted to 0.1mm(precision up to 0.1mm). The blade size can be customized according to customer requirements, and the length can reach 6m.

6. Avariety of air inlet diameters and positions are available, screw or pagoda air inlet can be selected to meet the requirements of screw connection or hose connection, convenient installation.

7. The air knife is matched with the hot air fan, which can be used for hot air drying and hot air rapid drying, avoiding the use of oven and other large investment, energy consumption drying methods.

8. The air knife is made of aluminum alloy or stainless steel. The aluminum alloy air knife is electroplated in the manufacturing process, and its service life is much longer than other similar products.

9. Air knife products are packed in wooden cases, with one year after-sales service and lifelong maintenance.

10. The air knife can drain 40 times the ambient air, and the gas consumption is only 1/5 of the traditional air blowing pipe;

11. "Full air flow" design, that is, the width of the air knife is exactly the same as the width of the air curtain blown by the air knife. There are installation and connection screw holes on the back of the air knife, which can be combined with the required length as required;

12. There are no wear parts inside the air knife, the internal gasket is made of stainless steel, the service life is more than 10 years;

Features and application of aluminum alloy air knife:

Aluminum alloy air blades produce powerful air curtains for a variety of blowing and air cooling applications, such as:

1, Electronic industry: electronic circuit board before assembly quickly dry.

2, Chemical industry: before labeling or packaging, the surface chemical substances or water blowing.

3, Beverage canning and bottling: before labeling, inkjet or packaging, the bottle mouth or bottle body moisture and attachment shall be blown off.

4, Automotive industry: used to blow off the manufacturing of additional water, coolant, dust, debris, and so on, as well as steel plate painting before blowing cooling, drying, dust.

5, Rubber and plastic industry: blow off the dust or debris on the surface of the product. Dry before extrusion or injection. The product is cooled after injection forming.

6, Food and medicine: before manufacturing or packaging, the water and attachment to blow off, or bag before opening and bag dust.

7, Metal industry: blowing coolant or other liquid from the metal surface. Purge mill emulsion. Dry or cool the surface before polishing, electroplating and painting.

8, Printing (inkjet) : inkjet, dust, debris, water vapor blowing before printing, or used in rapid drying ink.
