Ceramic Pall ring packing is commonly used in chemical scrubbers to increase the specific surface area of ​​the filter media. So, how do we differentiate between mass? Ningbo Hangyuan Chemical Equipment Technology Co., Ltd. teaches you four ways to distinguish:

       Look: Mainly start with the color of the ceramic Pall ring filler to see if the surface of the Pall ring is smooth. If the color is round, it means it was fired with good kaolin. Also check to see if there are many black spots on the surface of the Pall ring. If the black spots are small and inconspicuous, the iron removal process is not bad. There is also the roundness and beauty of the Pall ring. If the roundness and beauty are good, it means that the manufacturer's processing technology is better.

       Listening: Judging from the timbre of the porcelain rings, the two porcelain rings are in contact with each other, and listen quietly with your ears. If the sound is crisp and not muddy, it's a fine ceramic Raschig ring. It shows that the ceramic ring has been burned through during the sintering process. On the contrary, the quality is substandard and there is no burn through. Unfired Raschig rings will affect service life.

       Lick: Take a finished product and lick the surface of the ceramic Pall ring with your tongue. If the surface of the ceramic ring is wetted immediately, it means that the water absorption rate is high and the ceramic ring has not been completely porcelainized. Instead, it's a good porcelain ring.

       Throwing: Take a finished ceramic Pall ring and drop it from a height to test its strength. The standard test is that a ceramic ring thrown from a height of 5 meters will not break, and the appearance is intact, that is, a good ceramic Pall ring, and vice versa.

       Ceramic Pall ring packing is a kind of equal-diameter open-hole ring packing developed on the basis of ceramic Raschig ring. 16-38mm is a single-layer window. For diameters of 50mm and above, the upper and lower windows are staggered. Generally, the opening area accounts for about 30% of the total area of ​​the ring wall, so that the gas and liquid in the packed tower can freely pass through the window, improve the distribution of gas and liquid, and make full use of the surface of the inner wall ring.
