随着对济南钢结构防腐要求的提高以及环境保护限制,钢结构涂料防腐涂料更进一步地朝着低溶剂、高固体成份的方向发展，致使涂料变得高粘度、厚浆型而越来越难于喷涂。传统的施工方法是手工刷涂和空气喷涂，手工刷涂不仅效率低下，而且不可避免的会留下刷痕，其漆面效果难于令人满意.高压无气喷涂机将涂料用高压喷射雾化成细小的微粒，使其均匀地分布于工件表面，形成光滑、致密的涂层，这是刷涂等原始方法所无法比拟的。

　　With the Ji'nan steel structure anticorrosion requirements increase and environmental restrictions, coating for steel structure anticorrosion coating further towards the low solvent, high solids content direction, resulting in high viscosity, coating becomes thick and are becoming more and more difficult to spray. The traditional construction methods are manual brushing and air spray, manual brush is not only inefficient, but also inevitably leave brush marks, and its finish effect is satisfactory. The high pressure airless spraying machine will paint with high pressure spray into small particles, which are uniformly distributed on the surface of the workpiece to form a smooth, dense, coating, this is the brush and original methods incomparable.

　　济南钢结构高压无气喷涂采用高压喷射雾化，使涂料微粒获得强有力的动能，涂料微粒借此动能射达工件空隙之中，因而使涂层更密，与工件的机械咬合力增强，附着力提高，有效延长涂层寿命。

　　Ji'nan steel structure high pressure airless spraying with high pressure spray, paint particles obtained strong kinetic energy to kinetic energy, the paint particles reach the workpiece gap, so that the coating is dense, and the workpiece mechanical bite force enhancement, enhanced the adhesion, prolong the service life of the coating.

　　普通钢材以喷砂法进行除锈处理，除尽铁锈、氧化皮等杂物。表面处理质量控制应达到GB8923《涂装前钢材表面锈蚀等级和除锈等级》标准规定的Sa2 ，表面粗糙度35～75μm，喷砂后将灰尘除尽。

　　工件在加工、运输、存放等过程中，表面往往带有氧化皮、铁锈制模残留的型砂、焊渣、尘土以及油和其他污物。要使深层能牢固地附着在工件的表面上，在涂装前就必须对工件表面进行清理，否则，不仅影响涂层与基体金属的结合力和抗腐蚀性能，而且还会使基体金属在即使有涂层防护下也能继续腐蚀，使涂层剥落，影响工件的机械性能和使用寿命。因此工件涂漆前的表面处理是获得质量优良的防护层，延长产品使用寿命的重要保证和措施。

　　Ordinary steel rust treatment by sand blasting, rust, oxide skin removing all. The surface treatment quality control should reach GB8923 "steel surface before Coating Rust grades and preparation grade" standard of Sa2, the surface roughness of 35 ～ 75 μ m, after the dust removal

　　The workpiece in the processing, transportation, storage process, the surface oxide skin, often with rust die residual sand, welding slag, dust and other dirt and oil. In order to make deep can be firmly attached on the surface of a workpiece, prior to coating must be clear, on the surface of the workpiece to otherwise, not only affects the binding force of the coating and the base metal and the corrosion resistance, but also to the base metal in even with protective coatings are able to corrosion, the coating peeling, influence the mechanical properties and the the service life of workpiece. Therefore, the surface treatment before painting is to obtain excellent quality protection layer, and an important guarantee for extending the service life of the products.
