    环氧地坪漆施工后为什么会起皮?怎么预防解决?

    大家会发现市面上有的环氧地坪很结实,有的环氧地坪漆却很容易破损,当然原因有很多方面。现在市面上什么人都可以做地坪漆,专业的不专业的,鱼龙混杂,所以同样的东西做出了不同的品质,今天给大家普及一下环氧地坪漆大面积起皮破损的原因:环氧地坪漆涂装前表面处理不佳,被涂物表面上有油污、蜡,水汽、灰尘和化学药品等。或表面预处理后至涂漆旅工的间隔时间过长涂装前被涂物表面应处理清洁,并应立即涂装施工。底漆选择不当。如底漆的硬度过大。涂膜表面太平滑.都会使面漆和底漆间失去应有的黏附力应选用附着力和润湿性好的底漆。

    You will find that some epoxy flooring is very strong, and some epoxy flooring paint is easy to break, of course, there are many reasons. Nowadays, everyone on the market can make floor paint, professional and unprofessional, mixed with fish and dragon, so the same thing has made different qualities. Today, we will popularize the reasons for the large area of skin damage of epoxy floor paint: poor surface treatment before painting, oil stain, wax, vapor, and water vapor on the surface of the coated objects. Dust and chemicals. Or if the interval between surface pretreatment and painting travelers is too long, the surface of the coated object should be treated and cleaned, and the painting construction should be carried out immediately. Inappropriate choice of primer. If the hardness of primer is too high. If the surface of the coating is too smooth, the primer with good adhesion and wettability should be chosen.

    一、施工人员的过失或者是施工人员的经验不足

    1. The fault of the builder or the lack of experience of the builder

    1、涂装前地表的处理不是很好,被涂物表面上有油污、蜡、水汽、灰尘和化学药品等,或表面预处理后至涂漆施工的间隔时间过长。

    1. The surface treatment before painting is not very good. There are oil, wax, water vapor, dust and chemicals on the surface of the coating, or the interval between surface pretreatment and painting construction is too long.

    2、被涂物表面的光滑过度,而没有进行针对性处理或没有选择针对性底涂材料。

    2. Excessive smoothness on the surface of the coated material, without specific treatment or selection of specific primer materials.

    3、在底漆未干透之前就罩面漆或清漆,涂膜易发生开裂或脱落;

    3. Before the primer is dry enough, the coat or varnish is liable to crack or fall off.

    4、涂膜太厚,由于表层已干透,而底层干得慢或未干透,在干燥过程中由于面漆收缩过甚而引起开裂脱落;

    4. Coating film is too thick, because the surface has dried through, while the bottom dried slowly or not thoroughly, during the drying process, cracking and peeling are caused by excessive shrinkage of topcoat.

    5、施工环境温度高,涂装距离(喷涂)大,稀释剂挥发快,致使环氧地坪漆漆膜未流平,就使漆膜出现起皱橘皮现象。为了加快涂膜干燥,催干剂加入量太大,也会造成环氧地坪漆涂膜起皱。在高温下避免施工,或加强通风,降低施工环境温度,调整喷漆距离,适当加入慢干溶剂,减少催干剂用量,是避免和克服环氧地坪漆涂膜起皱的方法。

    5. The high temperature of the construction environment, the large painting distance (spraying) and the fast volatilization of diluent cause the floor paint film not to be leveled, which makes the paint film appear wrinkle orange peel phenomenon. In order to speed up the drying of the coating, too much drying agent will cause wrinkling of the epoxy floor paint. Avoiding construction at high temperature, or strengthening ventilation, reducing construction environment temperature, adjusting spray distance, properly adding slow-drying solvent and reducing the amount of drier are the methods to avoid and overcome the wrinkling of floor paint film.

    6、底漆表干未完全干硬,或固化剂含量不足,地坪漆漆膜交联不充分就涂装面漆或多涂,即发生起皱咬底现象。使用聚合物含量高的硝基漆或水性漆作底漆,由于PVC含量低,也造成复涂面漆咬底。如面漆使用大量慢干的酮类等强溶剂,也容易使环氧地坪漆产生咬底现象。
