Abstract
Description
technical field
[0001] The invention relates to the field of building material testing equipment, in particular to a building coil testing device. Background technique
[0002] Building waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls. The non-leakage connection between the foundation and the building is the first barrier for the waterproofing of the entire project and plays a vital role in the entire project. Building waterproof membranes have long-term exposure to wind, sun, rain, wear, corrosion, etc., requiring good water resistance and stability to temperature changes; not brittle at low temperatures, certain mechanical strength, elongation and fracture resistance property, must have certain flexibility and anti-aging properties, etc., if the compressive strength properties of building waterproofing membra...
