Yuan Lei tells you | bulk filler of industrial ceramic filler


Industrial ceramic fillers have good corrosion resistance, heat resistance and good surface wetting properties, and are cheap, and are currently widely used in gas absorption, gas washing, liquid extraction and other processes.

The bulk packing is a particle body with a certain geometric size, which is piled up in the tower. There are mainly the following.




Rassey ring packing

Rassey ring packing was invented by Rassey (F. Rashching) in 1914 and is a ring with an equal outer diameter and height.




Ball ring packing

Ceramic pall ring packing is a kind of open-hole ring packing with equal height and diameter developed on the basis of ceramic raschie ring. each layer of window hole has 5 tongue leaves, each tongue leaf turns inward to the center of the ring, and the upper and lower layers of window holes are staggered in opposite positions. Due to the opening of the ring wall, the gas and liquid in the packed tower can pass through the window freely, which improves the gas-liquid distribution and makes full use of the inner surface of the ring. Compared with Raschie ring, the gas flux can be increased by more than 50%, and the mass transfer efficiency can be increased by about 30%, which is a kind of packing with wide application.




Step ring packing

The stepped ring absorbs the characteristics of the Raschier ring, while the improvement of the Bauer ring, the ratio of the height to diameter of the ring is 1:2, and a tapered flanging is added at one end, which reduces the resistance of the gas passing through the bed and increases the flux. The filler has higher strength. Due to its structural characteristics, the gas-liquid distribution is uniform, the gas-liquid contact area is increased and the mass transfer efficiency is improved. Its comprehensive performance is better than that of Pall ring, and it is the most excellent one in the ring packing used.




arc saddle filler

Arc saddle filler is a kind of saddle filler, its shape is like a saddle, generally made of porcelain materials. The characteristic of the arc saddle filler is that the surface is all open, regardless of inside and outside, the liquid flows evenly on both sides of the surface, the surface utilization rate is high, the flow channel is arc-shaped, and the flow resistance is small. The disadvantage is that it is easy to overlap, resulting in a part of the filler surface is overlapped, so that the mass transfer efficiency is reduced, and the strength is poor, easy to break, and the application in industrial production is not much.



Moment saddle filler

In order to overcome the disadvantage that the arc saddle filler is easy to overlap, the moment saddle filler changes the arc surface at both ends of the arc saddle filler to a rectangular surface, and the two sides are different in size, so that the filler will not overlap when stacking, the liquid distribution is more uniform, and more pressure-resistant, simple configuration.

Wet mica powder is widely used, not only in coatings but also in rubber. Below, the editor will take you to understand the application of wet mica in rubber.

Yuan Lei's Little Knowledge | Performance Requirements and Types of Fillers for Coatings


Fillers in coatings are usually white or slightly colored pigments with a refractive index less than 1.7. It has the basic physical and chemical properties of pigments used in coatings, but due to its refractive index being similar to the film-forming material, it is transparent in coatings and does not have the coloring and covering power of coloring pigments. It is an indispensable pigment in coatings.

Yuan Lei's Little Knowledge | Application Effects of Different Mineral Powder Materials in Coatings


In architectural coatings, commonly used mineral materials include barium sulfate, calcium carbonate, kaolin, mica powder, talc powder, quartz powder, silica micro powder, transparent powder, glass powder, wollastonite powder, etc. Reasonable application of various mineral materials can effectively improve or enhance the performance of coatings. Let's take a look at the application of different mineral materials in coatings.
