How to identify the authenticity of sbs composite waterproofing membranes?

There are several ways to identify the product

1. Pay attention to the product name and packaging mark standards, the product packaging should be marked with the company name, product label, production date or batch number, production license number, storage and transportation precautions, product marking should be strictly enforced standards, consistent with the product name, Must not be ambiguous or incompletely marked and have no production mark. When users select these products, they must pay attention to the product mark and recognize the product name because the mark represents the identity of the product. For example, the coils produced with polyester-cotton non-woven fabric-grid composite tires can only be named as bituminous composite tires flexible waterproof membranes or composite tire membranes, and can not be named sbs membranes, and their product markings can only be Press compound tire standard mark.

2. The identification of genuine and false sbs from the foundation can generally be visually identified from the cross section of the product.

At this time, it can be concluded that the product must be a composite tire membrane. What kind of composite tire membrane material needs to be observed through the physical property test-soluble content test to observe the exposed tire base. However, only the polyester or glass fiber fibers are exposed after the pure polyester tire and glass fiber tire are torn.

3. From the perspective of physical inspection, the quality of visual inspection can only distinguish whether it is composite tire membrane or sbs and app membrane. However, it cannot be judged whether the selected product meets the quality requirements. This requires the user to go to the technical organization with the inspection ability and press the corresponding The product standards carry out the physical performance inspection of the factory items including soluble content.
