無氣噴砂機(jī)能對平板類金屬工件進(jìn)行表面清理、表面前處理、表面光飾等表面處理。無氣噴砂機(jī)能夠加工處理的平板類金屬工件的尺寸：工件的寬度可以是600mm，1000mm，1250mm，1400mm，1800mm，2500mm；工件的長度不限。
目前金屬或非金屬平面的表面除銹、亞光效果處理的基本方式是化學(xué)方式和機(jī)械加工方式兩大類。這兩種方式都不同程度上存在環(huán)境污染、損耗多、效率低等問題。
噴砂的動力為采縮空氣，在加工同樣寬度的幅面時功率消耗較大，加工出來的表面的均勻性及光澤度偏差也較大。拋丸設(shè)備是由核心部件拋丸器采用離心拋射原理來處理工件，對工件形狀及材質(zhì)都有嚴(yán)格要求，且加工同幅面的工件時設(shè)備較大。這兩種機(jī)械加工方式在加工薄板時都很難處理好變形問題。
無氣噴砂機(jī)利用從高壓風(fēng)機(jī)吹出的氣流在出砂口前端產(chǎn)生負(fù)壓，吸動從砂嘴口落下的砂料，再在后續(xù)氣流的推動下吹到工件表面，由于砂嘴的孔徑一定且在下砂嘴本體上布置的間距一定，保證了吹砂加工的均勻性。其與已有技術(shù)相比，不需要酸堿腐蝕等化學(xué)處理，減少了環(huán)境污染，能耗較低；加工成本低，工件變形量小，產(chǎn)品表面加工效果均勻度高、表面質(zhì)量好。
無氣噴砂清理機(jī)應(yīng)用于金屬或非金屬平面的表面除銹、亞光效果處理的機(jī)械方式加工等領(lǐng)域，例如鋼板的除銹以及玻璃、鋁板、不銹鋼板和塑料板等亞光效果的加工處理。機(jī)械加工方式，目前國內(nèi)大部分采用噴砂和拋丸，噴砂在加工同樣寬度幅面的工件時因動力為壓縮空氣，所需功率大，加工出來的工件表面的均勻性和光澤度偏差量也較大；拋丸設(shè)備是由核心部件拋丸器采用離心拋射原理處理工件，對工件形狀和材質(zhì)都有要求，且加工同樣寬度幅面的工件時設(shè)備較大。以上兩種機(jī)械加工方式在加工薄板或超薄板時都很難處理好變形問題。
無氣噴砂清理機(jī)的技術(shù)與已有技術(shù)相比，因具有表面加工均勻度高、表面質(zhì)量好、能耗較低、工件變形量小、不需要酸堿腐蝕等化學(xué)處理的優(yōu)點(diǎn)而減少了環(huán)境污染，同時加工成本低。其主要原理是利用從高壓風(fēng)機(jī)吹出的氣流在出砂口前端產(chǎn)生付壓，吸動從砂嘴口落下的砂料，再在后續(xù)氣流的推動下吹到工件表面，由于砂嘴孔徑一定且間距均勻，從而保證了吹砂加工的均勻性。技術(shù)優(yōu)點(diǎn)為表面均勻性提高以及光澤度偏差降低，加工同樣寬度幅面的工件時，所需能耗僅是常規(guī)噴砂加工的1/2。

Airless blasting machine for flat metal workpiece surface cleaning, surface treatment, surface finishing and surface treatment. Airless blasting machine is capable of processing the flat metal workpiece size: workpiece width can 600mm,1000mm,1250mm,1400mm,1800mm,2500mm; the length of the workpiece is not restricted.
The metal or non metal surface rust, Matt effect processing is the basic way of chemical and mechanical processing method of two categories. These two modes have different extent of environmental contamination, loss, low efficiency problem.
Blasting power for mining air, in the processing of the same width format when power consumption is larger, the processed surface uniformity and brightness deviation is larger. Shot blasting device is composed of the core components of shot blasting machine with centrifugal projection principle to the workpiece, the workpiece shape and material has strict requirements, and processing the same format when the workpiece equipment is larger. These two kinds of mechanical processing method in the processing of sheet metal are very difficult to deal with problems of deformation.
Airless blasting machine using high-pressure wind blown from the air flow in the sand outlet end generates negative pressure suction mouth, moving from the sand falling sand, then in the subsequent flow driven by blowing into the workpiece surface, since the sand mouth aperture and under the sand mouth body layout spacing, guarantee blowing sand processing uniformity. As compared with the existing technology, does not need the acid-base corrosion, chemical processing, reduce environmental pollution, lower energy consumption; the processing cost is low, the deformation of workpiece surface processing effect of small, product uniformity, good surface quality.
Airless blasting machine used in metal or non-metallic surface derusting, Matt effects processing mechanical processing and other fields, such as steel, aluminum, stainless steel cleaning and glass plate and plastic board and Matt effect processing. Mechanical processing, most of the current domestic blasting and blasting, blasting in the processing of the same width of the workpiece when power is compressed air, the required power big, the processed workpiece surface uniformity and brightness deviation amount is large; shot blasting equipment is composed of core part by centrifugal projection principle of Shotblast processing workpiece, to workpiece shape and materials are required, and the processing of the same width of the workpiece when equipment is larger. The above two kinds of mechanical processing method in the processing of thin or ultra-thin plate are very difficult to deal with problems of deformation.
Airless blasting cleaning machine technology compared with the existing technology, because of its surface processing uniformity, good surface quality, low energy consumption, small deformation of workpiece, does not need the acid-base corrosion chemical processing advantages and reduce environmental pollution, and low processing cost. Its main principle is to use from the high pressure wind blown from the air in the sand outlet end produce pay pressure, suction operated from the sand mouth falling sand, then in the subsequent flow driven by blowing into the workpiece surface, since the sand mouth aperture and uniform spacing, so as to ensure the uniformity of blown sand processing. Technical advantages of surface evenness is improved and the gloss deviation decreases, processing the same width of the workpiece, the energy consumption is only conventional sandblasting processing 1/2.
