Ⅱ. What are the full adhesion methods in the construction method of needle punch nonwoven?

1. Before the construction of the needle punch nonwoven, we need to lay the coil material on the surface of the base layer first, without bonding first, pay attention to the smooth and straight and flat material when laying the coil material, and the material cannot be twisted, and then cut.

2. Fold the long sides of multiple needle punch nonwoven in half, apply adhesive to the folds of the base layer and the surface of the coil, and when the adhesive is dry enough to not stick to the hand, close and paste the surface of the pre-laid waterproofing membrane, and compact it with a pressure roller.

3. Fold the unfolded part, continue to use the above method to paste and compact, and then carry out the butt welding construction.

4. The special parts of needle punch nonwoven are used for waterproofing membrane construction, and the corresponding additional layers should be made.

5. Before the construction of the needle punch nonwoven is completed, the waterproof membrane should be temporarily fixed to avoid being blown away by strong winds.
