Polyurethane rock wool sandwich board adopts special M6 self tapping screw to fix purlin, which can resist typhoon and other external forces. The self tapping screw is set at the vertex of the upper surface of roof panel, and adopts special waterproof structure to avoid the weakness of thin waterproof. What are the aging treatment methods of this sandwich panel? The following is the arrangement of Xiaobian:

1.拆下聚氨酯岩棉夹芯板，底板，除锈抛光。

1. Remove the polyurethane rock wool sandwich board and base plate, remove rust and polish.

2.使用专用防腐底漆进行施工。聚氨酯岩棉夹芯板腐蚀特别严重的部位应涂重防腐底漆

2. Use special anti-corrosion primer for construction. The parts of polyurethane rock wool sandwich board with serious corrosion shall be coated with heavy anti-corrosion primer

3.因为聚氨酯岩棉夹芯板的厚度为0.32mm，所以喷涂了两次特殊的防腐表层。

3. Because the thickness of polyurethane rock wool sandwich board is 0.32mm, special anti-corrosion surface is sprayed twice.

4.用刷子涂抹或喷洒滚筒。

4. Apply or spray the roller with a brush.

聚氨酯岩棉夹芯板广泛用于钢结构厂房、简易活动房的屋面、墙体、空气洁净室的吊顶与隔断。岩棉块之间和岩棉与上、下层钢板之间通过强度高的发泡剂粘接而形成整体，精良的生产工艺保证了高密度的岩棉隔热体与金属板内壁之间能产生比较强的粘着力，从而使岩棉夹芯板具有很好的刚度。

Polyurethane rock wool sandwich board is widely used in the roof, wall of steel structure workshop and simple movable room, and the ceiling and partition of air clean room. The rock wool blocks and between the rock wool and the upper and lower steel plates form a whole through the bonding of high-strength foaming agent. The excellent production technology ensures that a relatively strong adhesion can be generated between the high-density rock wool heat insulator and the inner wall of the metal plate, so that the rock wool sandwich plate has good stiffness.

在聚氨酯岩棉夹芯板的生产中，可以在表面粘贴聚乙烯粘合剂保护膜，以避免在运输和安装过程中划伤或磨损钢板表面涂层。

In the production of polyurethane rock wool sandwich board, polyethylene adhesive protective film can be pasted on the surface to avoid scratching or wearing the surface coating of steel plate during transportation and installation.
