安徽钢结构浅谈钢结构表面喷砂除锈工艺参数控制

发布时间:2015-11-21 10:10:11 浏览次数:522
钢结构表面喷砂除锈质量及压缩空气压力、喷嘴私立流速、停留时间等因素有关。压缩空气压力愈大,私立流速更大,更大的稽查,除锈质量要求所需时间越短;喷嘴停留越久,更高的质量,除锈。
喷砂除锈后表面呈均匀的润饰,润饰主要及砂的硬度,扩展及喷射工艺等因素有关。铁的硬度大,不多、颗粒粗,有血니시大。一般石英砂的硬度比较。经过粉碎、筛选后获得的许多角落,粒度分布均匀,通过石英砂。砂除锈后表面使用,真的好피니点。
影响表面润饰的喷射工艺参数主要压缩空气压力、喷嘴直径、喷射角度、间距等。压缩空气的压力大,喷嘴直径,沙子般的气势立即大有大的니시考虑耐压胶管等设备承压能力和我特高压的操作人员的后座力影响,压缩空气压力和喷嘴直径必须控制的适当范围。喷涂距离,喷射角度没有融化애다效果及除锈质量也有很大影响,对喷距离小,私立的冲量作用面积大,还有私立小,密度大的作用都是为了消除融化提高了效率的地上完成大的喷射角度为45°时;生产的粗糙度最大。

值得注意的是压缩空气的压力相当大,时间和距离都存在浪费问题,增加民办私立的损坏程度如何随压缩空气压力增加和减少而撒距离的增加为私立的再使用率很低。


Steel rust blasting structure and surface quality of the compressed air pressure, nozzle flow, private residence time and other factors. Compressed air pressure is bigger, greater private velocity, greater inspection, derusting quality requirements the shorter time; nozzle stay longer, more high quality, rust.
After sand blasting surface is uniform and the main polish, polishing sand hardness, expansion and injection technology and other factors. The hardness of iron, not much, coarse, blood big home. Comparison of the hardness of the quartz sand. After crushing, many corners of the corner, the size distribution is uniform, through the quartz sand. The use of sand surface rust, really good home.
The influence of injection process parameters of surface polishing the main air pressure, nozzle diameter, spray angle, distance etc.. Compressed air pressure, nozzle diameter, sand like momentum immediately with the recoil of the bearing ability of the pressure hose and other equipment and I UHV operators consider the, compressed air pressure and nozzle diameter must be controlled. Spraying distance, jet angle is not melting arrived effect and derusting quality also has a great influence and of spray distance is small, private impulse large area, and private, small and large density function is to eliminate melt improves the efficiency to complete the spray angle is 45 DEG; production of the roughness maximum.
It is worth noting that the pressure of compressed air is very large, time and distance are wasted, increasing the degree of damage to private private, and reduce the increase in the pressure of air pressure and the increase of the distance of the spread is very low.
