BAIJIAN - Third party testing organization
There are many types of waterproof rolls、 and asphalt type waterproof rolls are mainly made of natural substances such as asphalt、 petroleum asphalt、 and kerosene asphalt、 which have strong waterproof and anti-corrosion properties and are durable in use. Rubber plastic waterproof rolls、 made from materials such as butyl rubber and polyurethane、 have good tensile strength and elongation. And the weather resistance is also good. Use firmly and firmly. Cement based waterproof membrane has good waterproof、 moisture-proof、 and anti-seepage effects. Metal waterproof membrane can be used as a roof panel to prevent water damage. Below、 Baijian will introduce the knowledge of waterproof roll material testing Waterproof membrane testing items:
1. Appearance quality inspection includes: bubbles、 cracks、 scars、 bonding、 and holes.
2. Measurement of coil length、 thickness、 width、 straightness、 and flatness 3. Tensile strength、 elongation at break test、 low-temperature bending test、 permeability test、 perforation test、 thermal aging treatment test、 and heat treatment size change rate test
