Rubber Lining Adhesion Test

Once the test is complete you will want to record the force vs displacement.

Rubber lining adhesion test.

The vehicle engine mounts rubber coated metal components and rubber lined tanks and containers use the astm d429 standard. Method b 90 stripping test rubber part assembled to one metal plate. The astm d429 includes the test procedure to determine the adhesion of rubber to rigid metal substrates. 1 1 these test methods cover procedures for testing the static adhesional strength of rubber to rigid materials in most cases metals.

Chapter rubber compound and vulcanizate testing is related to the chapter on rubber raw material testing and provides a comprehensive description of the system of testing rubber compounds materials and vulcanizates starting from sampling and testing vessels up to evaluation of test results according to specific standards. The testing procedures include peel strength or tensile strength of the adhesion edge. Note before applying adhesive to the lining the rubber may require to be freshened by giving it a wipe with solvent. To read more about astm d413 astm d378 and the equipment req.

On metal substrates a more formal version of the knife test is the tape test. Method a rubber part assembled between two parallel metal plates. A standard method for the application and performance of this test is available in astm d6677. Adhesion testing is a critical aspect of multi component rubber products and frequently should be considered for both rubber to rubber interfaces and rubber to reinforcement interfaces.

Either the rubber material fails internally or at the adhesion surface to the metal. For polymer rubber linings qualification of procedures may include adhesion testing. Method e of astm d429 determines the adhesive strength of rubber tank lining to a tank wall using a 90 degree strip test. There are many conditions that can affect the adhesion of rubber to various substrates such as metal and fabrics.

The result is often critical to the acceptance or rejection of a coating process as the adhesion value quoted by. Pull off adhesion testing is widely used to assess the protective coating process and to determine if a coating is fit for service in new construction and for repairs to existing structures. Pressure sensitive tape is applied and removed over cuts made in the coating. The standard is divided into.

Relevant adhesion test results obtained during the last two projects performed by the lining applicator may be referred to in. This test peels rubber conveyor belting and measures the average peel force over a 5 section. There is no known correlation to other adhesion test methods pull off tape etc. Method c measuring adhesion of rubber to metal with a conical specimen.
