PVC Waterproofing Membrane is an advanced-formula, heat-weldable PVC thermoplastic membrane that is designed for long-term weather-ability and performance. The physical properties of the membrane are enhanced by a tenacious, weft-inserted polyester fabric that is encapsulated by thick PVC- based top and bottom plies.
The smooth surface of the PVC membrane allows for a total-surface fusion and permanent weld, creating a consistent, watertight, monolithic roof assembly. PVC can be used in adhered and mechanically fastened systems.

The new powerful anti-backing pad is made of special spring steel, and its anatomical surface is in the shape of a circular arc. The new powerful anti-backing pad can be divided into two types: 1: outer curved surface with anti-slip teeth, 2: inner The curved surface has anti-slip teeth, and the inner and outer curved surfaces have anti-slip teeth. The anti-slip teeth can be determined according to the direction of rotation of the nut. If the nut is locked clockwise, the anti-slip teeth can be designed to be clockwise. If the nut is locked counterclockwise, the anti-slip teeth will also be counterclockwise.
When the nut or bolt is tightened, the new strong anti-return pad will be axially squeezed, and the axial compression will deform the new powerful anti-back pad itself, then the new powerful anti-back pad will produce the shaft. Deformation and radial deformation, while axial and radial deformation will produce strong axial and radial stresses that enhance the friction between the workpiece and the new powerful backing pad and nut, resulting in a nut It is difficult to loosen with the workpiece, and the new powerful anti-backing pad has six non-slip teeth, which further strengthens the friction between the nut and the new powerful anti-back pad and the new strong anti-back pad and the workpiece. The cutting force is formed, which ultimately makes the workpiece more tight.
New powerful backing pad
In view of the deficiencies of the prior art, the present invention provides a new type of strong backing pad with reasonable structure, strong loosening performance and convenient use.
