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.
Rubber linings find a variety of applications within the framework of heavy duty corrosion protection. even slightly conductive materials can be tested for defects
After the rubber lining is completed, conduct an electrical leakage test on the electric spark tester to repair the defective parts of the rubber lining pipe. 6. inspection of the rubber lining no pits, imprints or inclusions exceeding 0.5mm are allowed on the surface, no delamination of the rubber lining the aforementioned bonding strength ...
Industrial rubber lining. cameron steel has twenty five years of rubber lining experience in mining, oil and gas, marine, power generation, water treatment, pulp and paper, pumps and other industrial uses. rubber is applied primarily as a wear liner to reduce corrosion and abrasion.

Additionally, the elasticity of a rubber lining easily accommodates thermal expansion and contraction as well as vibration. the major benefit of a rubber lining is simply its thickness. linings for rubber lined tanks are usually applied at a thickness of about 14quot.
The method is used for glue or other materials used when rubber is vulcanized. method e evaluates the adhesive strength of rubber tank lining to a tank using a 90degree strip test. the pulling load required to separate a rubber strip from a metal surface is measured at a 90
Both rubber linings in the factory as well as on a construction site have to go through a final inspection according to din en 14879 ex din 28055. also here, porosity testing is normatively required.
The proper way to spark test is to calibrate the voltage to a known leak. this procedure is detailed below. the purpose of spark testing is to determine if there are leaks in the rubber lining, and if so, their locations. the purpose is not to test the conductivity of the rubber lining. in testing, one must be careful not to cause pinhole damage to the rubber.
