彩钢板一般几次漆比较好
氨基漆一般是在烘烤、喷涂氨基漆。我们使用的油漆溶剂不能太强，否则会起皱。应该提前测试。如果使用少量油漆，喷漆。如果使用大量油漆，彩钢板喷漆材料建议使用真正的高氯化面漆。亮度好，硬度好，防伪性好。
聚酯漆一般用于彩钢瓦。如有特殊要求，
彩钢板喷漆材料可采用水性涂料。目前，几乎所有的墙面涂料都是水性涂料。建议北京市采用富雅水性涂料。在购买时，你应该乐观，并表明你正在购买。目前市场上
彩钢板喷漆材料使用的彩钢瓦采用热塑性喷涂工艺。聚氨酯薄膜具有优良的耐候性。但不能承受酸碱腐蚀，使用寿命12-14年（宝钢制造），漆膜呈粉状。
我们的建议必须加倍。为什么两次？你不能再做一次吗？两次通行的费用也很高。在面漆喷涂市场上，基本的要求是覆盖板表面或底漆不得渗漏，这是最基本的要求。如果在喷涂面漆后可以看到底漆暴露在外，则说明面漆太薄，需要更慢、更仔细地喷涂，或者再反向喷涂。注意，好反转方向，因为
彩钢板喷漆材料波峰的某些角落很难喷洒，所以可以完全喷洒。
2只要有专业的施工工艺，漆膜厚度也必须完全符合要求，不存在任何问题的可能。为什么油漆后不久会有剥落和爆裂？一是产品不够专业；二是施工前屋面的一些处理不到位，喷涂太薄
Amino paint is generally in baking, spraying amino paint. The paint solvent we use should not be too strong or it will wrinkle. It should be tested in advance. Spray paint is best if a small amount of paint is used. If a large amount of paint is used,
it is recommended to use a real high chlorinated topcoat. Good brightness, good hardness, good anti-counterfeiting.
Polyester paint is generally used for color steel tile. If there are special requirements, water-based coatings can be used. At present, almost all wall coatings are water-based coatings. It is suggested that Fuya waterborne coatings should be used in
Beijing. When buying, you should be optimistic and show that you are buying. At present, the color steel tile used in the market adopts the thermoplastic spraying process. Polyurethane film has excellent weather resistance. However, it can not withstand
acid and alkali corrosion, and its service life is 12-14 years (made by Baosteel), and the paint film is powdered.
Our suggestion must be twice. Why twice? Can't you do it again? The cost of two passes is also high. In the market of topcoat spraying,
the most basic requirement is that the covering plate surface or primer shall not leak, which is the most basic requirement. If the primer can be seen exposed after spraying the top coat, it means that the top coat is too thin and needs to be sprayed
more slowly and carefully, or spray again in the opposite direction. Note that it is best to reverse the direction, as some corners of the wave crest are difficult to spray, so that it can be completely sprayed.
2. As long as there is professional
construction technology, the film thickness must also fully meet the requirements, there is no possibility of any problems. Why do some flake and burst soon after painting? One is that the products are not professional enough; the other is that some treatment
of the roof before construction is not in place and the spraying is too thin
