special structure of piezo ceramic

The quality of piezo ceramic rings depends on the control of powder and sintering degree, from the naked eye,it is fine and smooth texture, smooth surface, color milk white for superior, (this kind of ceramic interior micro-hole, can see the description of the hole is not very precise.) ) The market on the six-corner is much better than the round.

piezo ring has durable glass ring, but the glass ring ring is more easy to cultivate digestive bacteria, but the piezo rings are to use some of the better , ph glass ring is lower than piezo ceramic ring, the ph of the glass ring is between 7.0-7.5, the ceramic ring is around 7.5-8.0.

Which is currently the highest rate of use and penetration of biochemical filter materials, because the adoption of different piezo bimorph actuator is fired, so there are different call, ceramic ring is a relatively early product, because of its effective, now gradually replaced by glass ring, now also extends out a lot of different varieties, ordinary glass ring, breathing glass ring, according to the size of the different, Also appears the big ring, the small ring, including the porcelain bead and so on, but the main principle is the same, is uses its special structure, the pore to parasitic more nitrifying bacteria. But piezo knock sensor does not have the physical filtration function, therefore must use in the filter cotton such material behind.40khz piezo ceramic disc has the surface of large pores, unit volume weight light, not easy to break, powder.

Piezo ring does not need regular cleaning is also one of its major characteristics, cleaning the time do not all the cleaning, but to the partial component of the cleaning, so as to avoid excessive loss of nitrifying bacteria, and the piezo ring pickup price has too much fluctuation. Use the water in the cylinder when cleaning, do not flush with the running water, the life of the glass ring now there is a certain controversy, many people think that do not need to replace, in fact, this is wrong, the glass ring is mainly used to parasitic nitrifying bacteria, bacteria will gradually die, piezo ceramic cylinder will be washed away with the water, but there is still a part of it will remain on the Such years of accumulation, will cause the internal porosity is getting smaller and affect the number of nitrifying bacteria, reduce nitrification, according to their actual situation, generally 1-2-year replacement can be.
