Overview
Jiangxi Dier Equipment shares with you the laboratory Kanon packing, developed in the UK in 1949. It is made of many thin stainless steel metal sheets punched with small holes, but the punching does not remove the metal, but makes it protrude and become a rough surface, which is conducive to the wetting of the liquid on the packing surface. Unlike the metal wire mesh spiral coil packing, which must be wetted multiple times before distillation, it is an efficient packing used in laboratories with high mechanical strength and theoretical tray number. It is particularly suitable for laboratory small and pilot distillation tower experiments, as well as mixed packing in large industrial towers. Therefore, it has high mass transfer performance,

1、 Overview and specification parameters of Canon fillers
Produced by Jiangxi Pingxiang Dier Chemical Packing Co., LtdKanon filling materialAlso known as rolled hole packing or rolled piercing hole mass transfer packing, it is an efficient and regular packing designed specifically for chemical separation processes. The filler is made of thin-walled stainless steel strip processed by precision rolling technology, and its surface is formed with a large number of micro scale spike like protrusions through special forming technology, significantly enhancing the spreading and wetting performance of liquid on the filler surface, thereby improving the mass transfer efficiency between gas and liquid phases.

2、 Key influencing factors on the quality of Canon fillers
1. Substrate quality
Filler material (usuallyThe quality of 304/316L austenitic stainless steel directly affects its performance. High purity and low inclusion stainless steel raw materials ensure that the filler has excellent mechanical properties and corrosion resistance. Jiangxi Pingxiang Dier Chemical Packing Co., Ltd. uses high-quality stainless steel strips to produce packing materials that can maintain structural stability in various chemical environments, ensuring long-term reliability of mass transfer performance.
2. Rolling forming process
The core forming process of Kanon filler is the rolling and piercing processing of metal strip. This process forms a raised structure on the surface of the strip through precision molds without material removal. The geometric accuracy, consistent stamping depth, and uniform distribution of protrusions of the forming mold directly determine the roughness characteristics and capillary structure of the filler surface, which in turn affects the liquid film-forming effect and wetting efficiency.
3. Precision of molding equipment
The mechanical accuracy of rolling forming equipment (including guiding accuracy, stamping stability, mold alignment accuracy, etc.) plays a decisive role in the batch consistency of filler geometry dimensions. Mold wear or deterioration of equipment accuracy can lead to size deviation and shape distortion of packing units, which can easily form uneven flow channels during filling in the tower, induce non ideal flows such as channel flow, and ultimately affect separation efficiency.
3、 Performance evaluation index system for Kanon fillers
1. Mechanical strength
The filling material needs to withstand its own gravity, gas-liquid scouring force, and possible pressure fluctuations during the filling and operation process. Carnon packing with sufficient mechanical strength can maintain structural integrity and resist plastic deformation and damage during long-term operation, thereby ensuring the stability of the internal flow channel structure and reliable mass transfer performance of the tower.
2. Theoretical number of tower plates
Theoretical number of tower plates（NTSM， The theoretical number of plates per meter of packing is the core parameter for quantitatively evaluating the mass transfer efficiency of packing. This indicator directly reflects the ability of the packing to achieve component separation during the distillation process. Canon packing has stable and high theoretical tray numbers under different specifications, which can meet the requirements of different separation difficulty systems for the number of mass transfer units.
3. Mass transfer performance
The mass transfer performance comprehensively reflects the contact efficiency of gas-liquid two-phase on the packing surface. The rolled microporous structure on the surface of the Kanon filler increases the effective mass transfer area, promotes the uniform spreading and renewal of the liquid film, and thus strengthens the interphase mass transfer process. The quality of mass transfer performance ultimately manifests as the separation ability of the tower and the purity of the product.
4. Stability
Stability includes two dimensions: chemical stability and physical stability
（1）chemical stability：The filler material needs to withstand chemical corrosion from various process media (including acids, alkalis, organic solvents, etc.) to ensure that there is no deterioration such as corrosion or leaching during the service life.
（2）Physical stability：Under conditions such as temperature fluctuations and pressure changes, the geometric structure and macroscopic performance of the packing material should remain stable to ensure the repeatability and reliability of the separation process.
