高壓清洗機在鋁板帶清洗設備上的應用近年來隨著我國國民經濟的高速發展,航空航天、家用電器、裝飾材料及飲料行業等對鋁帶、箔的需求越來越大,帶來了PS基材、鋁塑帶、電容器箔、制罐料等高精度鋁板帶材的快速發展。這些產品對平直度、潔凈度要求非常嚴格,而高精度鋁帶材通常是采用全油冷卻潤滑軋制的,其表面殘留大量的軋制油和鋁粉,因此要獲得良好的表面質量,必須清洗去掉其表面殘留物。
In recent years, with the rapid development of China's national economy, the demand for aluminum strip and foil in aerospace, household appliances, decorative materials and beverage industry is increasing, which brings the rapid development of PS substrate, aluminum plastic strip, capacitor foil, canning material and other high-precision aluminum strip. These products require very strict flatness and cleanliness, and high-precision aluminum strips are usually rolled by oil cooling and lubrication. There are a lot of rolling oil and aluminum powder on the surface of the strips. Therefore, in order to obtain good surface quality, the surface residue must be cleaned out.
另外對于板形要求較高鋁帶材還要進行拉彎矯直,拉彎矯直使帶材在拉仲和彎曲的作用下,逐步產生塑性延仲并釋放板材內應力,以改善板帶材在冷加工時產生的波形、翹曲、側彎和潛在的板形不良等缺陷,從矯直工藝考慮,首先必須對帶材表面進行清洗。
In order to improve the waveform, warpage, lateral bending and potential flatness defect of aluminum strip during cold working, stretching and bending straightening should be carried out. First, the surface of the strip must be cleaned.

清洗原理鋁板帶在冷軋制過程中,因軋輥與鋁板表面摩擦和碾壓,其表面會產生細微的氧化鋁粉脫落和吸附,軋制油及其附帶懸浮成分會殘留在鋁板表面,對鋁板帶復合、涂裝等成品加工造成不利影響。而目_拉彎矯直時由于帶材在輥上產生劇烈彎曲變形,對帶材施加的張力一部分轉化為帶材對張力輥的壓力,并較終形成摩擦力,帶動輥組。
Cleaning Principle Aluminum strip in cold rolling process, because the roller and the surface of aluminum plate friction and rolling, its surface will produce fine aluminum oxide powder shedding and adsorption, rolling oil and its associated suspension components will remain on the surface of aluminum plate, aluminum plate and strip composite, coating and other products processing adverse effects. However, due to the sharp bending deformation of the strip on the roll, part of the tension applied to the strip is transformed into the pressure of the strip on the tension roll, and finally the friction force is formed to drive the roll group.
因此,如果帶材表面未經清洗,變形時氧化鋁粉脫落,隨著油污一起x附在張力輥的輥面,使輥面產生磨損,并造成鋁板略傷,故必須通過專門的清洗裝置進行清洗。清洗就是利用壓力泵對清洗介質加壓,對帶材表面進行非接觸式噴洗或接觸式刷洗,使材料表面的鋁粉油污溶解脫落到清洗介質中,再經擠干輥擠干和高壓空氣吹掃,甚至高溫空氣烘干,以獲得潔凈干燥的鋁帶材。同時,通過不斷補充清洗介質與在線循環過濾系統同時使用,使清洗介質保持足量和清潔,并大大節約熱能和清洗介質。目前,鋁加工行業的拉彎矯直機常用的清洗介質有清洗劑(或稱溶劑油)、軟化熱水、化學溶劑,并各有優缺點。
Therefore, if the surface of the strip is not cleaned, the alumina powder will fall off when it is deformed, and X will be attached to the surface of the tension roll along with the oil stain, which will cause wear and tear on the surface of the roll and cause slight damage to the aluminum plate, so it must be cleaned by a special cleaning device. Cleaning is to use the pressure pump to pressurize the cleaning medium, non-contact spray cleaning or contact cleaning of the strip surface, so that the surface of the material aluminum powder oil dissolved off to the cleaning medium, and then extruded by the extrusion roller drying and high-pressure air blowing, or even high-temperature air drying, in order to obtain clean and dry aluminum strip. At the same time, by continuously supplementing the cleaning medium and using the online circulating filter system simultaneously, the cleaning medium can be kept adequate and clean, and the heat energy and the cleaning medium can be greatly saved. At present, the cleaning media commonly used in stretch-bending straighteners in aluminum processing industry are cleaning agents (or solvent oil), softening hot water, chemical solvents, and each has its advantages and disadvantages.
高壓水射流的噴射距離高壓水射流是靠密實的流束直接噴射而產生巨大的打擊力,密實射流和直接噴射二者缺一不可。射流流束以噴嘴中心線呈對稱布置,而是發散分布,射流一般分為三段。原始段,長度用L,表示,這段射流的特點是沿軸向的動壓力值兒乎是常數,射流尖端的動壓和噴嘴出口的動壓是相同的。另一特點質地非常密實,質點兒乎不和空氣相混和,因此該段的打擊力較強,主要用于清洗堅硬的結垢物,基本段,長度用Lz表示,這段射流的特點是空氣開始與水射流相混合,形成了空穴和渦流,因此該段的打擊力適中,適合各種設備及物料的清洗。
The distance between high-pressure water jet and high-pressure water jet is the direct injection of dense beams, which produces tremendous impact force. The jet flow is symmetrical in the center line of the nozzle, but diverges and distributes. The jet is generally divided into three segments. The original section, length expressed in L, is characterized by a constant axial dynamic pressure, and the dynamic pressure at the tip of the jet is the same as that at the nozzle exit. Another feature is that the texture is very dense and the particles are hardly compatible with the air, so this section is the strongest hit, mainly used to clean the hard dirt, the basic section, length expressed in Lz, this section of jet is characterized by air and water jet mixing, forming cavities and eddies, so the impact of this section is moderate, suitable for Cleaning of various equipment and materials.
