对喷砂角铝进行喷砂表面处理时，喷砂设备应尽可能靠近工作，以减少管道长度和压力的损失，降低管道磨损的概率，对操作人员也很方便联系。为更好地减少班次，防止出现空排或泄漏，提高磨料的利用率和工作效率，施工前要综合考虑，合理安排注入位置，拟定注入途径。
When performing sand blasting surface treatment for sand blasting angular aluminum, the sand blasting equipment shall be as close to the work as possible to reduce the loss of pipe length and pressure, reduce the probability of pipe wear, and facilitate the contact of operators. In order to better reduce shifts, prevent empty discharge or leakage, and improve the utilization rate and work efficiency of abrasive materials, comprehensive consideration shall be given to reasonably arranging the injection location and formulating the injection path before construction.
胶管受力喷砂角铝喷砂表面处理，要求减少压力损失和磨料对胶管的集中磨损。对于施工中必须弯曲的地方，要经常变换方向，使磨损均匀，延长软管的使用寿命。喷砂角铝喷砂表面处理时，应根据气压、喷嘴直径、处理质量、结构表面锈蚀状态、效率等因素及时调整料气比。
The rubber hose is subject to force sandblasting, and the angle aluminum sandblasting surface treatment is required to reduce the pressure loss and the concentrated wear of abrasive on the rubber hose. For places that must be bent during construction, the direction shall be changed frequently to make the wear uniform and prolong the service life of the hose. During the surface treatment of sand blasting angular aluminum, the material gas ratio shall be adjusted in time according to the air pressure, nozzle diameter, treatment quality, structural surface corrosion status, efficiency and other factors.

要根据气压、出砂量和结构表面的污染情况灵活掌握喷嘴的移动速度。喷砂角铝喷砂表面处理前，如发现母材表面有污染或生锈，必须重新处理。
The moving speed of the nozzle shall be flexibly controlled according to the air pressure, sand production and the pollution of the structure surface. Before the surface treatment of sand blasted angular aluminum, if the base metal surface is found to be contaminated or rusted, it must be treated again.
加工检验合格后，对喷砂角铝表面进行喷砂处理，并尽快喷涂。间隔越短越好。在潮湿或工业大气压等环境条件下，必须在4小时内完成涂装，晴天或温度不太高时长间隔不得超过12小时。喷砂角铝表面喷砂处理后，用干燥、无油的压缩空气清除漂浮的灰尘和杂物，清洁后的表面不得用手触摸。
After the processing inspection is qualified, the sandblasted angular aluminum surface shall be sandblasted and sprayed as soon as possible. The shorter the interval, the better. Under humid or industrial atmospheric pressure and other environmental conditions, the coating must be completed within 4 hours, and the interval between sunny days or when the temperature is not too high shall not exceed 12 hours. After sand blasting of angular aluminum surface, use dry, oil-free compressed air to remove floating dust and debris. The cleaned surface shall not be touched by hands.
此外铝板生产厂家提醒您，在选样时要挑选粘度适中的贴膜。在铝板生产中，贴膜的合理选择是关键。贴膜的粘度过低则贴不住。贴膜容易脱落，给喷涂带来相当大的难度。贴膜的粘度过大，说明贴膜上的胶比较多，当贴膜撕掉后，容易将贴膜上的胶粘在型材上，影响型材的表面质量，另一方面，在选择贴膜时，尽可能选用胶的成分与涂漆成分一致或相接近，这样可减轻对漆膜色泽的影响。
In addition, the aluminum plate manufacturer reminds you to select a film with moderate viscosity when selecting samples. In the production of aluminum plate, the reasonable choice of film is the key. If the viscosity of the film is too low, it will not stick. The film is easy to fall off, which brings considerable difficulty to spraying. If the viscosity of the film is too large, it means that there are more glue on the film. When the film is torn off, it is easy to stick the glue on the film to the profile, which will affect the surface quality of the profile. On the other hand, when selecting the film, the composition of the glue should be consistent with or close to the paint composition as far as possible, so as to reduce the impact on the color of the paint film.
