4 Test principle

The dipped canvas and rubber molding samples made of a certain order blanks, after curing become prepared sample. Using tensile testing machine at a constant

The speed of the sample and the adjacent layer canvas canvas delamination was measured during the peeling peel force peak, the value of the ratio of the width of the specimen and the

Adhesive strength dipped canvas; minimum ratio of the peel force and the specimen width is minimum adhesive strength of the sample. Calculation two release sample surface

Rubber coverage, rubber coverage with a smaller value as the sample.

5. Apparatus

This section uses constant elongation (CRE) type tensile testing machine. The testing machine shall meet the following technical requirements.
