TEIDE REFRACTORY SOLUTIONS, S.L. DOES SPECIAL IMPACT TESTS IN ORDER TO IMPROVE THE QUALITY OF THE MATERIALS; EXTRUDED PIECE AGAINST PRESSED PIECE

Most common tests in ceramic manufacturing are compression, tensite, flex. They provide information how a material will function when subjected to a static load over an extended period of time.

Ceramics under tests absorbs the load slowly. This shows good information about basic properties but does not give useful information regarding several real situations. Then, an impact test is required. Another reason is the slow, difficult and more expensive confection of test bodies according the actual norms: accurate saw, drill, polish operations are necessary.

A relation between flexural strength and impact energy may be established along a series of comparative tests for each kind of ceramics. Impact energy is defined by the expression: E = ½ MV² .N

E measure in Newton.mM weight of the drop hammer (steel plate)V impact speed in m/sN number of strokes Impact tests for ceramic determine the energy absorbed by a material when struck by a moving object like a falling steel plate from a determined or variable heigh and or for by increasing the weight of the falling plate. Impact test expose ceramic materials to dynamic events forcing the material to absorb energy very quickly.

The information provided by this type of testing is useful to understand how the material will function in reality of aplications.

Series of increasing energy impact tests can establish the amount of impact force the material can withstand. Evidence of this can be seen after cracks or breaking failure .

Moreover, manufacturers of ceramic bodies can improve the final product by modifying its design and manufacturing process.

The shown machine, has been designed for testing ceramic plates situated on top of low thermal mass kiln cars. Geometry, size, thermal shock and lightweight characteristics have determined TEIDE REFRACTORY SOLUTIONS, S.L. to use the machine as a very useful complement to traditional tests.
