为防止施工时外界物体刻划、碰撞塑料门窗表面,出厂前其表面贴有一层透明的塑料面膜作保护层。但这层面膜受外界的气候变化和风吹日晒后极易老化,老化的塑料面膜不能整张揭撕下来,给施工带来不少麻烦。为防止塑料门窗面膜老化,施工时一定要认真控制塑料门窗面膜 In order to prevent external objects from being scratched and colliding with the plastic doors and windows during construction, a transparent plastic mask is applied as a protective layer on the surface before leaving the factory. However, the membrane is susceptible to aging due to changes in the weather and the weather. The aging plastic mask cannot be peeled off and the construction has caused a lot of trouble. In order to prevent the aging of the plastic door and window mask, the plastic door and window mask must be carefully controlled during construction.
