One of art, technological core be to have used denitrating catalyst, has that reaction temperature is lower, purifying rate is high, reliable for operation etc. excellent
Point.Flat catalyst is very important one kind in this kind of catalyst, has the higher market share.The product quality of catalyst
It will have a direct impact on denitration effect and service life.Plate-type denitration catalyst is stainless (steel) wire to be coated in by active material and through forging
It burns and is made, the adhesion strength of Plate-type denitration catalyst is its very important physical property, and adhesion strength is to catalysis
The service life of agent has a significant impact.In the high flue gas of the dustiness such as coal-burning power plant and cement plant, flying dust constantly washes away catalyst
Surface can lead to catalyst large area and peel off and collapse, in addition, it is strong that in boat diesel engine denitrification process catalyst can generate
Violent shock is dynamic, requires the adhesion strength of catalyst high.
Widely used flat catalyst adhesion strength detection method is to utilize axis of a cylinder bending tester in industry at present
Carry out qualitative detection, testing result is passed through and obtained with comparing card and compare, and detection error is larger.No standard measure urges flat denitration
Agent adhesion strength is detected and is evaluated, and is unfavorable for objectively evaluating catalyst performance, is unfavorable for control of product quality.
Summary of the invention
