The function of plastic step ring can not be ignored

Not only can fillers be divided into many different specifications, but they can also be divided into many different filler materials depending on the material. The range of many plastic fillers is relatively wide. For the type of material, plastic packaging is mostly one of the plastic step rings, this kind of packing has negligible advantages.

The ratio of height to diameter of plastic step ring is only common for Bauer ring, and because of the layout of tapered flanging, the resistance of gas passing through the bed layer is greatly reduced, and the larger flux is guaranteed. It is because of its structural characteristics that its irreplaceable advantages are created. At present, the main plastics used in China are polypropylene, polyethylene and polyvinyl chloride. However, plastic fillers are usually made of polypropylene with high material utilization.

The stepped ring packing has not only high temperature characteristics, but also acid resistance, so it will not cause any impact. Only in low temperature, the step ring made of this material has cold brittleness. The step ring should be selected before the PVC material needs to be packed to avoid affecting the cold brittleness.

In addition, the step ring made of plastic material has the advantages of light weight, low cost, impact resistance, not easy to break, etc. Therefore, it is often used in adsorption, extraction and dust removal devices.

As a kind of packing, the advantages and characteristics of plastic step ring are incomparable with other packing. Different fillers are suitable for different applications. When selecting, we must pay attention to select the appropriate filler according to the actual needs.
