喷砂处理能够除去铝加工件零件表面毛边(较为小的)，使表面产生凹坑状，为事后表面加工做准备，使表面产生受力层，提升表面限度。下面来讲讲工业铝型材喷砂进行表面处理操作九大要点。
Sand blasting can remove the rough edges (relatively small) on the surface of aluminum machined parts, making the surface concave, preparing for post surface processing, making the surface produce a stress layer and improving the surface limit. Next, let's talk about the nine key points of surface treatment of industrial aluminum profile by sand blasting.
⒈进行对工业铝型材喷砂表面处理操作时，喷砂设备尽量接近工作，降低管路长度以及压力的损耗，减少管道磨损机率，对操作人员联系也是挺方便的。
⒈ during the sand blasting surface treatment of industrial aluminum profiles, the sand blasting equipment should be close to the work as much as possible, so as to reduce the loss of pipeline length and pressure, reduce the probability of pipeline wear, and it is also very convenient for operators to contact.
⒉为了更好的减少移位次数，防止空放或者漏喷的出现，提高磨料利用率和工作效率，在施工前要多面进行考虑，合理安排喷射位置，拟定喷射路线。
2. In order to better reduce the number of shifts, prevent the occurrence of empty discharge or missed spraying, and improve the utilization rate and work efficiency of abrasive, it is necessary to consider multiple aspects before construction, reasonably arrange the spraying position and draw up the spraying route.
⒊软管力工业铝型材喷砂表面处理要求减少压力损失和磨料对软管的集中磨损，对施工中须弯折的地方，要经常调换方向，使磨损均匀，延长软管的使用寿命。
3. The sandblasting surface treatment of industrial aluminum profile requires to reduce the pressure loss and the centralized wear of abrasive on the hose. For the places that must be bent in the construction, the direction should be changed frequently to make the wear uniform and prolong the service life of the hose.

⒋对工业铝型材喷砂表面处理时由于空气压力、喷嘴直径、处理的质量、结构表面锈蚀状态、效率等对料气比及时进行调整.
4. During sand blasting surface treatment of industrial aluminum profiles, the material gas ratio shall be adjusted in time due to air pressure, nozzle diameter, treatment quality, structural surface corrosion state, efficiency, etc
⒌要对空气压力、出砂量及结构表面污染情况灵活掌握喷嘴移动速度。
5. The moving speed of the nozzle should be flexibly controlled according to the air pressure, sand production and structural surface pollution.
⒍对工业铝型材喷砂表面处理涂装前如发现基体金属表面被污染或返锈，须重新进行处理.
⒍ sandblasting surface treatment of industrial aluminum profiles. If the base metal surface is found to be polluted or rusted before painting, it must be treated again
⒎铝板生产厂家认为在处理好检查合格之后，尽快对工业铝型材喷砂表面处理并进行喷涂，隔时间越短越好。在潮湿或工业大气压等环境条件下，须在4h内涂装完毕，晴天或温度不大时，长间隔不超过12h。
⒎ the aluminum plate manufacturer believes that after the treatment and inspection are qualified, the sandblasting surface treatment and spraying of industrial aluminum profiles should be carried out as soon as possible, and the shorter the interval, the better. Under humid or industrial atmospheric pressure and other environmental conditions, the coating must be completed within 4H. In sunny days or low temperatures, the long interval shall not exceed 12h.
⒏工业铝型材喷砂表面处理后，用干燥、无油的压缩空气清除浮尘和碎屑，清理后的表面不得用手触摸。
8. After sand blasting surface treatment of industrial aluminum profile, use dry, oil-free compressed air to remove floating dust and debris, and the cleaned surface shall not be touched by hands.
