汽车漆面鼓泡起泡的修复方法——Repairing car paint bulging and blistering

汽车漆面鼓泡现象

涂膜表面出现较大的圆形鼓泡或气泡，通常出现在接缝区域或死角处，或在原子灰较厚的表面。

汽车漆面鼓泡主要原因

陷在涂膜下的空气发生膨胀，造成涂膜与基材分离。

①    由于底漆、原子灰等的施工不当。

②    涂膜连接处的羽状边(薄边)处理不当

③    用分质稀释剂或稀释剂不足、压缩空气的压力太高等.

④    涂膜盖在缝隙或死角上，使涂膜下面形成空隙。

⑤    没能正确地处理及封闭基材

汽车漆面鼓泡预防措施

①    正确地使用底漆、原子灰

②    正确地制作羽状边

③    避免涂料一次性喷涂过厚，以保证涂料渗入缝隙和死角。

④    使用推荐的稀释剂，并按正确的喷涂工艺操作，喷涂底漆时要喷得薄而湿

⑤    检查基材有无气孔，仔细清理并封闭基材

⑥    烘干涂膜时防止温度太高。

 

汽车漆面鼓泡修补方法

根据气泡的深度，将相应的涂膜全部磨掉，修补好下层缺陷后，重新补喷涂料。

Performance of automotive paint blisters

Large round bubbles or bubbles on the surface of the paint film, usually in the seam area or at dead ends, or on thicker atomic grey surfaces.

Main reasons for blistering

The air trapped under the paint film expands, causing the film to separate from the substrate.

① Due to improper construction of the primer, atomic plaster etc.

② Improper handling of the feathered edge (thin edge) at the joint of the coating film

③ Insufficient diluent or thinner, too high pressure of compressed air, etc.

④ The coating film is covered on the gap or dead corner, so that a void is formed under the coating film.

⑤ Failure to properly treat and seal the substrate

Preventive measures against blistering of car paintwork

① Correct application of primer and atomic grey

② Make the correct feathered edge

③ Avoid applying paint too thickly at one time to ensure that the paint penetrates into gaps and dead spaces.

④ Use the recommended thinners and follow the correct spraying process, spraying the primer thin and wet

⑤ Check the substrate for air pockets, clean and seal the substrate carefully

⑥ Prevent high temperatures when drying the paint film.

How to repair a bubble in car paint

According to the depth of the bubble, grind off all the corresponding coating film, repair the lower layer of defects and then repaint the paint.
