彩涂板基板的磨刷處理是通過堿洗液的溶解與刷子的機械摩擦等雙重作用來去除污垢。彩涂板生產線的磨刷處理是設計成機械式的，磨刷設備也叫刷洗機，通常由旋轉刷輥、刷輥貯藏箱刷輥電動控制裝置、堿液噴管循環系統組成。
暦刷處理工序一般設置在一二級脫脂段之間，采用特制的刷輥材料，配合堿液沖刷，對彩涂板基板上下表面進行旋轉式磨刷，其旋轉方向與鋼帶運行方向相同或相反，通過毛刷與基水膠院板表面的高速運動所產生的摩擦力，除去彩涂板基板表面黏附的臟物和粗糙的氧化物，使基板表面具有活性。
刷輥通常有兩種類型，壓縮型刷子和硬毛型刷子。壓縮型刷子是將粒度很細的碳化硅或氧化鋁磨料粘結在尼龍絲上，然后將這種尼龍絲制成纖維板或軟墊，經固化后切成一段段圓環筒套，裝在一根輥芯上制成刷輥。硬毛型刷子的刷體是用含有碳化硅磨料的尼龍絲編繞而成的。磨料粒度不同，用途也不同，兩種刷子相比較各有其優缺點。壓縮型刷子因點是由于尼龍絲較細容易撕裂，使用壽命短。硬毛型刷子的顯著優點是尼龍絲耐磨性好，含磨料粒度很細，并且刷輥對被刷板面的壓力較大，因此刷過的基板表面均勻一致，其缺因而使用壽命長，大約是壓縮型刷子的幾倍，但是這種刷子不宜用于處理薄板基板，板薄不僅處理效果不理想，而且還會造成基板卷曲。在使用刷輥式刷洗機的過程中，為防止尼龍絲過熱而熔化，應不斷向板面噴淋堿液，以便冷卻和潤濕。
The grinding and brushing treatment of the substrate removes dirt through the dual action of dissolving the alkali washing solution and mechanical friction of the brush. The brushing treatment of color painting production line is designed as mechanical, and the brushing equipment is also called brushing machine. It usually consists of rotary brushing roller, brushing roller electric control device of brushing roller storage box and alkali nozzle circulation system.
The process of drying and brushing is usually set between the first and second degreasing stages. The special material of brushing roll, together with alkali washing, is used to rotate the upper and lower surfaces of the substrate. The direction of rotation is the same or opposite to that of the steel strip. The friction produced by the high-speed movement of the brush and the surface of the base water glue yard plate is used to remove the substrate. Surface adherent dirt and rough oxides make the substrate surface active.
There are usually two types of brush rollers, compression brush and bristle brush. Compression brushes are made by bonding fine SiC or Alumina abrasives to nylon filaments, then making fiberboard or cushion from the nylon filaments, cutting them into a segment of ring cylinder sleeve after solidification, and mounting them on a roll core to make brush rolls. The brush body of the hard bristle brush is made of nylon wire containing silicon carbide abrasive. Abrasive particle size is different, the use is different, the two brushes have their own advantages and disadvantages. Compression brush is because nylon filament is thin and easy to tear, short service life. The notable advantages of hard brush are good wear resistance of nylon filament, fine abrasive particle size and high pressure of brush roll on the surface of the brushed board. Therefore, the surface of the brushed substrate is uniform and the service life of the brush is long, which is about several times longer than that of the compressed brush. However, this brush should not be used to treat the thin plate substrate. The treatment effect is not ideal, and will cause the substrate to curl. In order to prevent nylon filament from overheating and melting in the process of using brush roller scrubber, alkali solution should be continuously sprayed on the surface of the plate for cooling and wetting.
