铝板清洗的原理你知道是什么吗?

来源:

高压清洗机在铝板带清洗设备上的应用近年来跟着我国国民经济的高速开展,航空航天、家用电器、装饰材料及饮料行业等对铝带、箔的需求越来越大,带来了PS基材、铝塑带、电容器箔、制罐料等高精度铝板带材的快速开展。
In recent years, the application of high-pressure cleaner in the cleaning equipment of aluminium sheet and strip has been developing at a high speed in our national economy. The demand for aluminium strip and foil is increasing in aerospace, household appliances, decorative materials and beverage industries. It has brought the rapid development of PS base material, aluminium plastic strip, capacitor foil, canning material and other high-precision aluminium sheet and strip.
这些产品对平直度、洁净度要求十分严格,而高精度铝带材通常是选用全油冷却光滑轧制的,其外表残留很多的轧制油和铝粉,因而要取得良好的外表质量,有必要清洗去掉其外表残留物。
These products have strict requirements for flatness and cleanliness. High-precision aluminium strips are usually rolled with oil cooling and smooth rolling. There are a lot of rolling oil and aluminium powder remaining on their surface. Therefore, in order to achieve good surface quality, it is necessary to clean and remove the surface residues.
另外关于板形要求较高铝带材还要进行拉弯矫直,拉弯矫直使带材在拉仲和曲折的作用下,逐渐发生塑性延仲并开释板材内应力,以改善板带材在冷加工时发生的波形、翘曲、侧弯和潜在的板形不良等缺点,从矫直工艺考虑,首先有必要对带材外表进行清洗。
In addition, STRETCH-BEND straightening is also necessary for aluminum strips with higher shape requirements. Under the effect of STRETCH-BEND straightening, plastic extension and internal stress release gradually occur to improve the defects of waveform, warpage, lateral bending and potential bad shape during cold processing. Considering straightening process, it is necessary to clean the outer surface of strips first.
铝板带清洗原理及理论
Cleaning Principle and Theory of Aluminum Plate and Strip
清洗原理铝板带在冷轧制过程中,因轧辊与铝板外表摩擦和碾压,其外表会发生纤细的氧化铝粉脱落和吸附,轧制油及其顺便悬浮成分会残留在铝板外表,对铝板带复合、涂装等成品加工形成不利影响。而目_拉弯矫直时由于带材在辊上发生剧烈曲折变形,对带材施加的张力一部分转化为带材对张力辊的压力,并终究构成摩擦力,带动辊组。
Cleaning Principle Aluminum plate and strip in cold rolling process, because of friction and rolling between roll and aluminium plate, fine alumina powder will fall off and adsorb on its surface. Rolling oil and its suspended components will remain on the surface of aluminium plate and strip, which will adversely affect the processing of finished products such as aluminium plate and strip compounding and coating. The tension exerted on the strip is partly transformed into the tension roll pressure of the strip due to the severe bending deformation of the strip on the roll, and eventually constitutes the friction force, which drives the roll group.


因而,假如带材外表未经清洗,变形时氧化铝粉脱落,跟着油污一起x附在张力辊的辊面,使辊面发生磨损,并形成铝板略伤,故有必要经过专门的清洗设备进行清洗。
Therefore, if the strip surface is not cleaned and alumina powder falls off during deformation, X is attached to the roll surface of tension roll with oil pollution, which causes wear and tear of roll surface and slight damage of aluminium plate. Therefore, it is necessary to clean by special cleaning equipment.
清洗就是运用压力泵对清洗介质加压,对带材外表进行非接触式喷洗或接触式刷洗,使材料外表的铝粉油污溶摆脱落到清洗介质中,再经挤干辊挤干和高压空气吹扫,乃至高温空气烘干,以取得洁净干燥的铝带材。
Cleaning is to use pressure pump to pressurize the cleaning medium, to spray or brush the surface of the strip in a non-contact way, so that the oil pollution of the aluminum powder on the surface of the material can dissolve and fall off into the cleaning medium, and then be extruded by the extrusion roller, cleaned by high-pressure air, or even dried by high-temperature air, in order to obtain clean and dry aluminum strip.
一起,经过不断弥补清洗介质与在线循环过滤系统一起运用,使清洗介质保持足量和清洁,并大大节约热能和清洗介质。目前,铝加工行业的拉弯矫直机常用的清洗介质有清洗剂(或称溶剂油)、软化热水、化学溶剂,并各有优缺点。
Together, the cleaning medium is continuously compensated and used together with the online circulating filtration system to keep the cleaning medium in sufficient quantity and clean, and greatly save heat and cleaning medium. At present, the commonly used cleaning media of STRETCH-BEND Leveller in aluminum processing industry are cleaning agent (or solvent oil), softening hot water and chemical solvent, and each has its own advantages and disadvantages.
