How to distinguish whether the waterproofing membrane is polyester tires?
Waterproof membrane requirements have good water resistance, stability of the temperature change (high temperature does not flow, no blistering, not confuse; low temperature does not brittle crack), a certain mechanical strength, extensibility and resistance to fracture, to There is a certain degree of flexibility and anti-aging and so on.
Polyester tires (polyester fabric, polyester felt, polyester linoleum fabric) with high strength, high extension and puncture resistance, light weight, high tensile strength, good permeability, high temperature, anti-freeze, anti-aging, corrosion. Technical requirements, including the appearance of quality, intrinsic quality assessment projects and internal quality reference project, the indicators are in line with the provisions of the waterproof standards. Routine project tests should be in accordance with national standards test methods, thermal stability, bending, impregnation, water resistance test methods have done a detailed test.
The easiest way is: hand tear, because the polyester tire than the composite tire body more flexible, so the direct way is to tear the hand is "composite tire", on the contrary is the "polyester tire"
