Chemshun Tell you how is Polypropylene Pall ring packing working in packed tower

 Polypropylene Pall ring packing is widely used, which increases the direct economic benefits of chemical plants. Let us understand the application of polypropylene Pall rings in PVC. It has the advantages of simple structure, large empty tower speed change range and simple manufacture. Packed towers with a diameter of less than 1 meter are still widely used in PVC production enterprises. In the production of PVC, this packed tower usually uses corrosion-resistant non-metallic materials, such as ceramic packing.

The factory started to replace the ceramic packing with polypropylene Pall rings, which achieved good results, and there was no tower blockage caused by packing corrosion. Due to the light weight of the polypropylene Pall ring packing, the stacked weight is only 1/10 of the ceramic Raschig ring and 1/7 of the ceramic Pall ring, so the weight of the packing in the tower is greatly reduced, and the polypropylene Pall ring will not break and will not break. Produces debris that clogs pipes. But polypropylene Pall rings are lightweight and can easily be carried away by air currents, causing blockages in pipes and systems. A closing flower plate should be provided at the gas outlet. The use of polypropylene Pall rings to replace ceramic fillers has achieved good production benefits.

99% alumina bulletproof ceramics are the preferred materials for protective devices

图片
99% alumina ceramic bulletproof sheets, as a high-performance bulletproof material, are gradually becoming an important part of protective equipment in the military, police and some civilian fields. This bulletproof sheet is mainly composed of high-purity alumina (AI203), and its alumina content is as high as 99%, which gives it a series of excellent physical and chemical properties.   First of all, 99% alumina ceramic bulletproof tiles are known for their extremely high hardness and wear resistance. These characteristics enable it to effectively withstand high-energy impacts and reduce the possibility of penetration. At the same time, the compressive strength of alumina ceramics is also very high, which further enhances its bulletproof performance.   In practical applications, this bulletproof sheet can significantly reduce the penetration ability of bullets or other high-speed projectiles on target objects, providing users with reliable protection.   99% alumina cerami...

What is a packing Raschig ring?

图片
Industrial Raschig ring packing is the earliest artificial random packing used in industry. The common size range of Raschig rings is relatively large, and the commonly used size is 25mm - 75mm, but there are also special specifications as small as 6mm and as large as 150mm. When the Raschig ring is made of ceramic material, its wall thickness is usually 2.5mm - 9.5mm; if it is made of metal material, the wall thickness is 0.8mm - 1.6mm. Under the premise of ensuring strength, reducing the wall thickness as much as possible helps to reduce costs and weight, while increasing the specific surface area of ​​the packing. Large-sized Raschig rings (above 100mm) are generally filled in a regular manner in a whole-laying manner to ensure regularity and stability; while Raschig rings below 75mm are mostly filled in a random manner because they are easier to operate. The structural characteristics of the Raschig ring with equal height and diameter give it advantages such as simple structure, e...

What is ceramic tower packing used for

图片
Ceramic tower packing  is material widely used in many industrial fields. It has a wide range of uses, including chemical, metallurgical, acid, gas, oxygen, steel, pharmaceutical, fine chemical and other industries. Ceramic tower packing  are mainly used in towers, such as washing towers, cooling towers, recovery towers, desulfurization towers, drying towers, absorption towers and reactor linings to increase the contact area of ​​reactants, improve mass transfer and heat transfer efficiency, and promote chemical reaction rates. In addition, ceramic fillers are also used to support and fix catalysts or catalyst carriers to ensure their stable distribution in the reactor. Its main features are acid and alkali corrosion resistance and high temperature resistance, and it can withstand pressure, impact and wear under various harsh conditions. The raw materials of ceramic fillers are mainly ceramic materials, such as alumina, silicon oxide, zirconium oxide, etc. These materials usua...
