Chemshun Production process of wear-resistant ceramic tubes

Wear Resistant ceramic tubes is widely used for bulk material handling system , like coal or slurry material conveying , pneumati transport etc. Chemshun ceramics company share how to alumina ceramic tubes produced .

1. Powder calcination: Calcine the alumina ore powder according to different formulas to obtain calcined α-alumina powder suitable for production;

2. Powder grinding: Grind the calcined α-alumina powder according to the formula to prepare for the ceramic powder suitable for molding. Generally, wet ball milling is used;

3. Powder preparation: High-quality powder suitable for green body molding is obtained by spray granulation;

4. Molding: According to the requirements of product design, the high-quality powder after spray granulation is pressed by dry pressing or isostatic pressing to obtain qualified ceramic blocks or ceramic ring green bodies;

5. Sintering: The process of densification of the pressed green body, generally using electric kilns;

6. Installation: After the sintered ceramics are inspected and qualified, wear-resistant ceramic tubes are made by gluing, spot welding, lining ceramic rings, etc.

Pingxiang Chemshun company mainly produce industrial ceramics for wear resistance , types of ceramics with different shapes and materials exported to oversea market . welcome to inquire Chemshun Ceramics .office@chemshun.com   website : www.chemshun.com

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...
