Factory Introduction
Pingxiang Yongguang Chemical Packing Co., Ltd. was established in 2014. It has 50 employees and a factory area of 15,000 square meters. The factory focuses on the research, production and sales of inert alumina ceramic balls. The product specifications/models range from Φ3mm to 50mm of different particle sizes. They can meet the needs of scenarios such as petrochemical packing, environmental water treatment filtration, and catalytic reaction bed support. The factory attaches great importance to quality control and customized services to ensure stable product performance and provides stable supply.

Procurement Considerations
Clarify core performance parameters
Confirm key indicators based on actual working conditions to avoid excessive or insufficient performance.
Alumina content: For low-load filling, select around 75%; for high-temperature and high-pressure scenarios, it needs to be 92% or above.

Physical properties: Pay attention to compressive strength (≥80MPa) and water absorption rate (≤5%), and require the supplier to provide test reports.

Appearance dimensions: The surface should have no cracks or missing corners, and the size deviation should be controlled within ±2%, ensuring uniform filling.

Require sample trial use: If the purchase quantity is large, first take samples for testing to verify whether the performance meets expectations.

How to determine the quality of alumina balls?
To assess the quality of inert alumina balls, one can start from three aspects: appearance observation, performance testing, and qualification verification. This will help quickly screen out high-quality products. The specific methods are as follows:

1. Observe the appearance and size directly

Appearance: The surface should be smooth without cracks, corners, or pores, with uniform color and no obvious impurity spots. If the surface is rough or damaged, there may be sintering defects, which will affect strength and corrosion resistance.

Size: Randomly measure the size with a caliper. The size deviation of the same batch should be ≤ ±2%, and the ball should have good roundness and no obvious deformation; uneven size will lead to inconsistent filling density and affect the usage effect.

2. Verify the key performance parameters

The key performance determines the actual usage effect. It should be based on the test report or simple tests.

Simple test: Take 2-3 balls and gently collide them. High-quality balls will have a clear sound; if the sound is dull, there may be internal pores, and the strength is poor.

3. Verify the supplier and application cases

Indirectly judge the product stability to reduce procurement risks.

Supplier qualification: Preferentially choose manufacturers with ISO9001 quality system certification and long production history. These enterprises have more standardized quality control and better after-sales service.

Application cases: Ask if the product has been used in similar working conditions (such as petrochemicals, water treatment), and if there are long-term cooperation cases with large enterprises, the quality credibility is higher.

Would you like me to help you prepare a quick detection comparison table for the quality of inert alumina balls? The table will correspond the judgment points of appearance, performance, qualification, etc. with the standard values, making it convenient for you to quickly check on-site.
