White alumina ceramic nozzle

White alumina ceramic nozzle: a precision industrial component with high hardness, wear resistance, and corrosion resistance
In the fields of industrial sandblasting, dust removal, and chemical spraying, nozzle wear and corrosion are the main reasons for frequent equipment shutdowns and high production costs. The white alumina ceramic nozzle, as a new generation of high hardness and wear-resistant material, is designed specifically for high-speed dusty airflow and corrosive media due to its Rockwell hardness of HRA88 or higher and excellent chemical stability. It can not only withstand the severe impact during sandblasting, but also maintain its size without deformation in high temperature and acid-base environments. It is an ideal choice to replace traditional metal and hard alloy nozzles, aiming to help users achieve continuous production and significantly reduce the labor cost of replacing consumables.

Product Frequently Asked Questions (FAQ)
Q: My sandblasting machine nozzle was worn out in less than a week of use, and frequent replacement caused delays in the project schedule. Can your product solve this problem?
Answer: Absolutely possible. Our white alumina ceramic nozzle uses over 99% high-purity alumina raw material, with high density and fine grain size. Its wear resistance is dozens of times that of ordinary metal nozzles. It can ensure continuous and stable spraying for thousands of hours during sandblasting operations, greatly reducing the frequency of downtime and replacement.
Q: In a strongly acidic electroplating environment, ordinary metal nozzles are prone to corrosion and rusting. Is alumina ceramic nozzle corrosion-resistant?
Answer: White alumina is an inert material with strong chemical stability and can withstand the corrosion of most acids, bases, and organic solvents. In the chemical spraying environment, it will not undergo electrochemical corrosion like metals, and can maintain a smooth inner wall for a long time, ensuring consistent spraying atomization effect.
Q: There are various interface sizes and installation methods for different devices. Can you provide non-standard customization?
Answer: We support full-size customization. Whether you need standard threaded connections, flange installations, or diffusion nozzles with specific angles, we can complete mold opening and production in a short period of time based on the drawings or physical samples you provide, ensuring seamless integration with your equipment.

Product core advantage: Why choose alumina ceramics?

1. Super abrasion resistance
   The hardness of white alumina ceramics is second only to diamond, with a Rockwell hardness of HRA85-90. Its dense microstructure enables it to exhibit excellent erosion resistance when dealing with high hardness abrasives such as garnet, copper ore, and quartz sand, ensuring long-term stable spraying efficiency.
2. Excellent high temperature and corrosion resistance
   The melting point of alumina ceramics is above 2050 ° C, and it can work for a long time in high temperature environments. Meanwhile, its chemical inertness enables it to perform excellently in corrosive environments such as chemical and pharmaceutical industries, without contaminating the processed materials.
3. Stable dimensional accuracy and sealing performance
   We use cold isostatic pressing and precision sintering processes to ensure that the roundness and straightness tolerances of the nozzle inner hole are controlled at the micrometer level. The precise inner diameter size not only ensures the airflow velocity, but also perfectly matches the spray gun, avoiding pressure loss caused by air leakage.

Customer Application Cases
Case background: A large shipbuilding enterprise in East China (anonymous: Dongfang Heavy Industry) mainly engages in rust removal and sandblasting operations on the surface of ship hulls. The company originally used boron carbide nozzles, which are wear-resistant but brittle, prone to fracture, and expensive. They urgently need an alternative solution that combines high toughness, high wear resistance, and cost-effectiveness to meet the high-intensity, all-weather operational needs of shipyards.
Our solution:
After conducting in-depth research on the site, we recommended a specially designed reinforced white alumina ceramic nozzle. We optimized the buffer angle at the nozzle inlet to disperse the impact force, targeting the 20 mesh angular steel sand and 0.8MPa high-pressure gas used; At the same time, the nozzle jacket is designed with high toughness stainless steel material and embedded with a high-density alumina ceramic core, which not only utilizes the wear resistance of ceramics, but also protects the ceramic body through a metal jacket to prevent accidental impact and breakage.
Final effect:
Extended lifespan: After three consecutive months of on-site testing, the ceramic nozzle has an average lifespan of 950 hours, which is 1.5 times that of the original boron carbide nozzle, while reducing procurement costs by 40%.
Efficiency improvement: Due to the uniform and slow wear of the inner hole, the jet airflow remains stable in a fan-shaped manner, reducing repetitive operations caused by pressure fluctuations and increasing the overall rust removal efficiency by 15%.
Comprehensive feedback: The company has switched all vulnerable parts in its 12 sandblasting workshops to our white alumina ceramic nozzles, saving over 300000 yuan in annual consumables costs.
