1. How to choose a good quality PTFE Pall ring?

If you want to choose a good quality PTFE Pall ring, you need to do the following two points: First, clearly understand the use requirements, and determine the price range of products that you can afford, so as to further narrow the scope of choice; It is the choice of professional and regular manufacturers to ensure product quality and product performance, and in turn, to ensure the use of the product.

2. Why does the PTFE pall ring have non-stick properties and good insulation properties?

The PTFE pall ring is non-tacky because the PTFE material used has a small coefficient of friction and is one-fifth of that of polyethylene, and the intermolecular force of the fluorine-carbon chain is small, so polytetrafluoroethylene A PTFE material has no stickiness. The material has good insulating properties because PTFE has a low dielectric constant and dielectric loss over a wide frequency range, and its breakdown voltage, volume resistivity and arc resistance are relatively high. Therefore, based on these two points, this material has good insulation properties.

3. Is there any difference in the customization of the PTFE pall ring? Is it the same as other fillers?

PTFE pall ring, which can be customized, but if the product is customized, it is different from the standard product, at least in the calculation and determination of the product price, because if it is a customized product, The price of the product is recalculated and determined, which is not the same as the price of the standard product. The PTFE pall ring

 is mainly used for the full and intensive mixing of the gas phase and the liquid phase, and at the same time increases the contact surface between the gas phase and the liquid phase. Therefore, it is not specific to other fillers. the same.

4. What is the structure of the PTFE pall ring?

PTFE pall ring, which is a specific type of Pall ring, its reasonable structure is: two rows of holes with inner tongues are opened on the ring wall, and there are five rows per window. The lingual leaves bend into the ring and point to the center of the ring, almost at the center. In addition, the positions of the upper and lower windows are offset from each other. In the total area of the opening, it is about 35% of the entire ring area, which is more suitable, which can make the PTFE pall ring have a good use
