對噴砂角鋁進(jìn)行噴砂表面處理時，噴砂設(shè)備應(yīng)盡可能靠近工作，以減少管道長度和壓力的損失，降低管道磨損的概率，對操作人員也很方便聯(lián)系。為更好地減少班次，防止出現(xiàn)空排或泄漏，提高磨料的利用率和工作效率，施工前要綜合考慮，合理安排注入位置，擬定注入途徑。
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.
膠管受力噴砂角鋁噴砂表面處理，要求減少壓力損失和磨料對膠管的集中磨損。對于施工中建議彎曲的地方，要經(jīng)常變換方向，使磨損均勻，延長軟管的使用壽命。噴砂角鋁噴砂表面處理時，應(yīng)根據(jù)氣壓、噴嘴直徑、處理質(zhì)量、結(jié)構(gòu)表面銹蝕狀態(tài)、效率等因素及時調(diào)整料氣比。
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.

要根據(jù)氣壓、出砂量和結(jié)構(gòu)表面的污染情況靈活掌握噴嘴的移動速度。噴砂角鋁噴砂表面處理前，如發(fā)現(xiàn)母材表面有污染或生銹，建議重新處理。
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.
加工檢驗合格后，對噴砂角鋁表面進(jìn)行噴砂處理，并盡快噴涂。間隔越短越好。在潮濕或工業(yè)大氣壓等環(huán)境條件下，建議在4小時內(nèi)完成涂裝，晴天或溫度不太高時長間隔不得超過12小時。噴砂角鋁表面噴砂處理后，用干燥、無油的壓縮空氣清除漂浮的灰塵和雜物，清潔后的表面不得用手觸摸。
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.
此外鋁板生產(chǎn)廠家提醒您，在選樣時要挑選粘度適中的貼膜。在鋁板生產(chǎn)中，貼膜的合理選擇是關(guān)鍵。貼膜的粘度過低則貼不住。貼膜容易脫落，給噴涂帶來相當(dāng)大的難度。貼膜的粘度過大，說明貼膜上的膠比較多，當(dāng)貼膜撕掉后，容易將貼膜上的膠粘在型材上，影響型材的表面質(zhì)量，另一方面，在選擇貼膜時，盡可能選用膠的成分與涂漆成分一致或相接近，這樣可減輕對漆膜色澤的影響。
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.
