彩钢瓦的八个防腐喷涂技巧

防腐涂料能有效延长彩钢瓦的使用寿命,而普通涂料只能起到临时的表面覆盖作用,很快就会出现剥落现象,不能从根本上解决腐蚀问题,防止生锈现象的发生。八种彩涂卷防腐技巧如下:

1 彩涂卷防腐涂料应按规定比例配制,搅拌均匀。养护时间控制在30分钟以内。施工应在6小时内完成。涂装间隔不少于24小时,长度不超过7天。
2施工中使用的工具应清洁干燥,涂层不得混入水分、香蕉水、醇溶剂、汽油等杂质。涂料应在准备使用的6小时内进行喷涂,以防止形成胶水,造成不必要的损失,增加施工成本。
三。彩钢瓦厂家建议先用水枪冲洗彩钢瓦,然后用角形抛光机、钢丝刷、铁砂布等工具将基面上的灰尘、污垢、毛刺、水渍、油脂、老化漆层等清理干净。
4 彩涂卷防腐在喷洒前,应使用刷子或压缩空气将格栅表面、内拐角和凹槽上的灰尘清除干净。
5待基层表面清理合格后,方可进行喷涂。
6涂装施工应无渗漏、无锈粉。
7为防止二次污染,基层表面处理后应立即喷洒一次。
8施工温度5~35℃,相对湿度85%。在雨、雾、雪、粉尘较大的情况下,不能进行施工。

The anti-corrosion coating can effectively extend the service life of color steel tile, while the ordinary paint can only play a temporary surface covering role, and the phenomenon of peeling and falling off will appear soon, which can not fundamentally solve the corrosion problem and prevent the occurrence of rust phenomenon. The eight painting techniques are as follows:

1. The coating shall be prepared according to the specified proportion of the product, and evenly stirred. The curing time shall be controlled within 30 minutes. The construction shall be completed within 6 hours. The coating interval shall not be less than 24 hours and the length shall not be more than 7 days.
2. The tools used in the construction shall be clean and dry, and the coating shall not be mixed with moisture, banana water, alcohol solvent, gasoline and other impurities. The coating shall be sprayed within 6 hours when it is ready for use, so as to prevent glue formation, cause unnecessary loss and increase construction cost.
3. The manufacturer of color steel tile suggests that the color steel tile should be washed with water gun first, and then the dust, dirt, burr, water stain, grease and aged paint layer on the base surface shall be cleaned by angular polishing machine, steel wire brush, iron sand cloth and other tools.
4. Before spraying, the dust on the surface, inner corner and groove of the grid shall be cleaned with brush or compressed air.
5. The spraying layer can be applied after the base surface is cleaned and qualified.
6. Coating construction shall be carried out without leakage and rust powder.
7. In order to prevent secondary pollution, spray once immediately after base surface treatment.
8. The construction temperature is between 5 ℃ and 35 ℃, and the relative humidity is 85%. The construction can not be carried out under the conditions of rain, fog, snow and large dust.
