鋁板噴砂法砂面處理:用礦砂或河沙;鋁板刷砂法砂面處理:圓銅絲刷轉(zhuǎn)動,下面?zhèn)魉蛶箱X板一邊向前走一邊左右串動即可得到砂面;鋁板磨砂法砂面處理:用膠印淘汰下來的磨版機(jī)同樣磨鋁板,只是要不斷加水沖洗,即可得到細(xì)致光澤好的砂面效果;鋁板化學(xué)砂面處理:有專賣的化學(xué)砂面處理劑,通過化學(xué)處理,得到砂面鋁板效果,要求鋁板結(jié)晶細(xì)而均勻。
Sand surface treatment of aluminum sheet sand blasting method: with ore sand or river sand; aluminum plate brush sand method sand surface treatment: round copper wire brush rotation, the following conveyor belt on the side of aluminum plate on the side left and right side string to get the sand surface; aluminum plate grinding method sand surface treatment: the offset plate machine is eliminated with the same plate, just to continuously add water rinse, you can get meticulous Good gloss sand surface effect; aluminum sheet chemical sand surface treatment: the chemical sand surface treatment agent, through chemical treatment, get the effect of the sand surface aluminum plate, the aluminum sheet is fine and uniform.
選用厚度為1mm以上的鋁板,若鋁板過薄,則噴砂后容易變形。噴 砂處理前鋁板表面要進(jìn)行除脂處理,并用細(xì)木炭磨去其表面上的任何劃 痕,然后用粒度為70-90的沙子,在6kgmm2的壓力下,用噴槍均勻地噴射鋁板表面,保證噴砂均勻。然后鋁板再進(jìn)行化學(xué)拋光處理。噴砂工 藝的缺點(diǎn)是有粉塵污染,應(yīng)該有良好的除塵裝置。使用銅絲刷輪,以1500min的速度轉(zhuǎn)動,鋁板安裝在刷輪下面的工作臺上,刷砂時(shí)鋁板緩慢向前移動,同時(shí)左右竄動,經(jīng)過銅絲刷的刷磨,使鋁板表面呈磨砂效果。
If the thickness of the aluminum plate is more than 1mm, if the aluminum plate is too thin, it will be easy to deform after sandblasting. Before the spray treatment, the surface of the aluminum sheet should be treated with degreasing, and any scratches on the surface of the surface are worn out with fine charcoal. Then the surface of the aluminum plate is evenly sprayed with a spray gun under the pressure of the particle size of 70-90. The surface of the aluminum plate is evenly sprayed with a spray gun, so as to ensure that the sand is evenly sprayed. Then the aluminum plate is then chemically polished. The disadvantage of sandblasting is dust pollution, and there should be a good dust removal device. The copper wire brush wheel is used to rotate at the speed of 1500min. The aluminum plate is installed on the working table under the brush wheel. When the sand is brushed, the aluminum plate moves slowly forward and moves around the same time. Through the brush grinding of copper wire, the surface of the aluminum plate is sanding.
使用膠印制平凹版的磨版機(jī),用金剛砂或鋼球加適量水對鋁板進(jìn)行 磨砂處理。磨好后用清水清洗干凈、晾干,然后再進(jìn)行化學(xué)拋光。這種 方法可以代替噴砂處理。也有采用通常的流水方法進(jìn)行磨砂,磨砂后不 用進(jìn)行化學(xué)拋光就能得到銀白色的光澤均勻、精細(xì)的砂面,可制作儀表盤D。目前國內(nèi)外均有生產(chǎn)鋁板砂面處理用的化學(xué)砂面劑,鋁板經(jīng)過化學(xué)砂面劑的處理產(chǎn)生砂面效果。這種方法使用的鋁板要求質(zhì)量比較高,晶 粒比較均勻細(xì)致。
Using the offset printing gravure plate grinding machine, we use abrasive or steel ball to add aluminum to the aluminum plate. After grinding, rinse and dry with clean water, then do chemical polishing. This method can replace sand blasting treatment. There is also the use of ordinary water method for grinding, after grinding without chemical polishing can get a silver white gloss uniform, fine sand surface, can make the instrument panel D. At present, both domestic and foreign chemical surface agents for producing aluminum plate and sand surface are treated, and the effect of sand surface is produced by aluminum sheet after chemical sand treatment. The aluminum plate used in this method requires high quality and uniform grain size.
