济南彩钢瓦作为一种建筑材料在使用过程中褪色锈蚀现象频发，加上一些彩钢板使用年限已到，严重影响厂房使用，那么锈蚀的彩钢瓦怎么翻新合适呢？下面小编为您讲解。

Jinan color steel tile, as a building material, is frequently discolored and rusted in the process of use. In addition, the service life of some color steel plates has expired, which seriously affects the use of the plant. So how can the rusted color steel tile be renovated properly? The following editor will explain it to you.

使用专业设备开展打磨防锈处理或喷砂除锈，除锈以后表层不能有锈迹斑点存在，油渍、油脂，粉尘、铁砂及金属氧化物等清理整洁。防锈处理后、务必在6小时内喷底漆开展防腐蚀加工处理，开展喷漆工序前，如遇雨天或其余导致基体钢材表层潮湿的情况时，要等到自然环境达到施工条件后，用干燥的压缩空气吹干表层水以后防锈处理；

Use professional equipment to carry out grinding and rust prevention treatment or sand blasting for rust removal. After rust removal, there shall be no rust spots on the surface, and oil stains, grease, dust, iron sand and metal oxides shall be cleaned. After the anti-corrosion treatment, the primer must be sprayed within 6 hours to carry out the anti-corrosion treatment. Before the painting process, in case of rain or other conditions that cause the surface of the base steel to be wet, the surface water shall be blown dry with dry compressed air after the natural environment reaches the construction conditions to carry out the anti-corrosion treatment;

防锈处理后的钢材表层达到除锈等级Sa2.5，表层清理整洁，才可以开展下道工序，防锈处理达标后的钢材表层呈现出金属光泽，如在底漆前已起锈，再次打磨防锈处理或喷砂除锈，不可降低磨料规定，以防降低表面粗糙度。旧彩钢屋面防锈处理这步骤很重要，加工处理时要有耐心和仔细。

The next process can be carried out only after the surface layer of the steel after the anti rust treatment reaches the rust removal grade Sa2.5. The surface layer of the steel after the anti rust treatment reaches the standard shows metallic luster. If the rust has been removed before the primer, the anti rust treatment or sand blasting can not reduce the abrasive provisions to prevent the surface roughness from being reduced. The anti rust treatment of the old color steel roof is very important. Be patient and careful when processing.

可使用高压冲洗机设施，基层表层清理务必清洁，对表层间隙、凸凹位置、隐蔽角落里清理多面。表面规定务必牢固、整齐，针对凸凹不平或有裂缝的位置务必开展加固加工处理后再作业；表面务必清理整洁多面，不能有泥土污垢、浮尘、杂物、明水、油渍或松散物等杂质等，并随时随地留意保持表面清洁。

High pressure washing machine facilities can be used. The surface layer of the base layer must be cleaned, and the surface clearance, convex and concave positions and hidden corners must be cleaned. The surface must be firm and tidy, and the uneven or cracked positions must be reinforced before operation; The surface must be clean and tidy, free of dirt, floating dust, sundries, open water, oil stain or loose matter, and keep the surface clean at any time.

作业前，务必保持表面无浮锈、无湿迹、积水、清洁，不能在阴雨天气情况下开展作业。使用高压喷漆专业设备开展作业，施工材料务必无沉淀，通过严苛检验，包装桶打开以后尽可能当日使用完；喷漆材料在使用之前，务必使用专用碾磨机开展均匀分布搅拌，保证质量作业过程中高压喷漆专业设备无堵塞现象发生，喷漆过程务必均匀分布、无堆积、无遗漏。

Before operation, the surface must be kept free of floating rust, wet marks, accumulated water and clean. The operation cannot be carried out in rainy weather. Use professional high-pressure painting equipment to carry out the operation. The construction materials must be free of sedimentation and pass the rigorous inspection. After the packaging barrel is opened, it should be used up as much as possible on the same day; Before using the painting materials, the special grinding machine must be used to carry out uniform distribution and mixing to ensure that the high-pressure painting professional equipment is not blocked during the quality operation, and the painting process must be evenly distributed, without accumulation and omission.

针对角落里、边缝处、水平搭接、垂直搭接、风机口、伸出屋面管路、空调管路、金属材料板材与女儿墙交界处、螺丝固定件（墙壁边缘、C型钢、H钢、线槽、天花板吊杆、管路）等其余金属屋面（墙壁、室内）防腐蚀薄弱环节开展仔细检查，确定边缝角全部喷漆到位。

Carefully inspect the corner, side seam, horizontal lap, vertical lap, fan port, pipe extending out of the roof, air conditioning pipe, junction of metal material plate and parapet, screw fasteners (wall edge, C-steel, H-steel, trunking, ceiling suspender, pipe) and other weak anti-corrosion links of other metal roof (wall, indoor) to ensure that all side seam corners are painted in place.

务必在底漆表干实干以后才可以开展面涂作业，使用高压喷漆专业设备开展作业，作业后的防腐蚀涂层应厚薄均匀分布，符合设计规定；不允许有脱落，堆积裂缝、翘边、鼓包、分层，等不足。

The surface coating can only be carried out after the primer surface is dry. The high-pressure painting professional equipment shall be used for the operation. The thickness of the anti-corrosion coating after the operation shall be evenly distributed and meet the design requirements; It is not allowed to have defects such as falling off, stacking cracks, warped edges, bulging and layering.

作业保证质量表层整体无缝多方位遮盖，工程项目结束以后进入维护保养期，严禁所有人进入施工工地。更多关于改材料的使用注意事项就来我们网站http://www.jnhxtcg.com咨询了解吧。

The operation shall ensure that the quality surface layer is covered in a seamless and multi-directional manner. After the completion of the project, the maintenance period shall be entered. No one is allowed to enter the construction site. For more information about the use of modified materials, please visit our website http://www.jnhxtcg.com Consult and understand.
