The foam composite board is not only easy to use, but also cheap. And the most important thing is that it is green and pollution-free. Its production adopts new production process, and the recovery rate has been significantly improved. Understand the above knowledge so that we can better understand the 2 forms of the product's foam.
Ji'nan foam composite board
1. Denitrification foam
If the sewage plant is nitrifying, denitrification will occur in the sedimentation tank or under insufficient aeration, resulting in bubbles such as nitrogen, which will cause some sludge to float and foam.
2. Start the bubble.
Activated sludge process started early, because there are some surfactant in the sewage, it is easy to cause surface foam. However, with the maturation of activated sludge, the foam phenomenon of foam board will gradually disappear after biodegradation of these surface active substances.
1. Low temperature tempering: the microstructure obtained by low temperature tempering is tempered martensite. The purpose is to reduce the internal stress and brittleness of the quenched steel under the premise of keeping the high hardness and high wear resistance of the quenched steel, so as to avoid cracking or premature damage when using the foam composite plate.
2. Medium temperature tempering: the microstructure obtained by medium temperature tempering is tempered troostite. The purpose is to obtain high yield strength, elastic limit and high toughness.
3. High temperature tempering: the microstructure obtained by high temperature tempering is tempered sorbite. The heat treatment combining quenching and high temperature tempering is called quenching and tempering treatment. Its purpose is to obtain comprehensive mechanical properties with good strength, hardness, plasticity and toughness.
The above is about the secondary form of foam composite panels and the introduction of tempering related knowledge, so after you master this knowledge, you will be more simple in manufacturing.
