In modern ceramics, mining, lithium battery, chemical, coatings, and powder processing industries, grinding efficiency and material purity directly impact product quality and production costs. Compared to traditional steel balls and ordinary ceramic balls, high-performance alumina grinding balls, with their superior wear resistance, high hardness, low pollution, and long service life, are becoming the preferred grinding […]
Alumina-based materials are widely utilized across the catalyst, adsorbent, ceramics, petrochemical, and environmental protection sectors. Among these, pseudoboehmite has increasingly emerged as a key raw material for high-end catalyst supports and functional aluminas, owing to its exceptional molding properties, high specific surface area, and excellent dispersibility. During the procurement process, many clients frequently ask: What […]
High-quality alumina ceramic balls are characterized by high strength, high-temperature resistance, corrosion resistance, and low abrasion; however, during actual operation, some enterprises still encounter issues such as ceramic ball breakage, pulverization, severe wear, or elevated pressure drop. These problems not only compromise the stable operation of the unit but may also lead to catalyst deactivation, […]
As operating time increases, the adsorption capacity of activated alumina gradually declines. If not replaced in a timely manner, this not only affects the system’s dew point but may also lead to equipment corrosion, pipeline freezing, compromised product quality, and increased energy consumption. So, how can one accurately determine whether activated alumina desiccant has become […]
Different industries and operating conditions impose widely varying performance requirements on activated alumina powder adsorbents. An inappropriate product selection can lead to reduced adsorption efficiency, increased pressure drop, higher energy consumption, and even unstable equipment operation. How, then, should enterprises select the appropriate activated alumina powder adsorbent based on their actual operating conditions? This article […]
In industrial gas drying and adsorption systems, activated alumina is widely utilized—specifically in compressed air drying, natural gas dehydration, and PSA systems—due to its exceptional adsorption properties and mechanical strength. However, in actual operation, many users encounter two typical issues: · Severe pulverization (dusting) · Increased system pressure drop These issues not only compromise equipment […]
In modern industrial production, the efficiency of gas purification and drying technologies directly impacts equipment stability and product quality. As a key adsorbent material, activated alumina is widely utilized in fields such as air separation, petrochemicals, natural gas processing, and compressed air systems, owing to its exceptional adsorption properties and stability. Leveraging years of technical […]

Activated Alumina Key Characteristics: · Strong water absorption capacity; suitable for gas drying · Possesses a certain adsorption capacity for acidic gases such as H₂S, HF, and SO₂ · High mechanical strength, water-resistant, and highly regenerable Typical Applications: Compressed air drying, pretreatment for PSA systems, acidic gas […]
In industrial gas separation and purification processes, PSA (Pressure Swing Adsorption) systems are widely used in hydrogen production, oxygen production, nitrogen production, and gas drying. However, many users encounter a common problem in actual operation: decreased system efficiency, unstable gas purity, and continuously increasing energy consumption. Many people’s first reaction is to blame the equipment, […]
I. Why are membrane coating materials needed? In lithium-ion batteries, the membrane’s function is to isolate the positive and negative electrodes while allowing lithium ions to pass through. However, traditional polyolefin membranes (PE/PP) have significant problems: · Poor high-temperature resistance (shrinkage begins around 130℃) → prone to thermal runaway · Poor wettability → weak electrolyte […]
