First: Look at the appearance:
Excellent: A good waterproof canvas has good color and is very bright. Poor: No gloss or very dull gloss.
Second: Look at the degree of wear:
Excellent: Good waterproof canvas is very careful in the material ratio, and the degree of wear is small. After rubbing on the general ground or other hard objects, it can also have a waterproof effect.
Poor: Inappropriate material ratio. For example, if calcium powder is added too much, the tensile force is not large, it is easy to break, and the wear performance is poor. After friction on the ground, it will be damaged and cannot be used normally.
