Problems solved by technology

Waterproof membranes are widely used in the construction industry and are one of the important building materials. The existing self-adhesive membranes and modified asphalt membranes are relatively common. Although the self-adhesive membranes have good flexibility and adhesion Viscous, easy to bend, and convenient for construction, but its tensile strength is poor, its elongation at break is low, and its self-healing ability is weak; among them, although the modified asphalt coil has high strength, its viscosity is poor, and in Poor applicatio
