FAQ

Q: What is the standard pore size of 5A molecular sieve?

A: The standard pore size is approximately 5 Å (0.5 nm), which can adsorb small molecules and block larger molecules.

Q: What are the common particle sizes?

A: Common sizes are 1.6–2.5 mm spheres, 3.0–5.0 mm spheres, or 1.6 mm strips, which can be selected according to equipment requirements.

Q: Does the product need pretreatment before filling?

A: If the packaging is intact, it can generally be used directly; if it has been exposed to air for a long time, it is recommended to regenerate it before filling.

Q: What is the typical regeneration temperature?

A: Common regeneration temperatures are approximately 200–350℃, depending on the equipment process conditions.

Q: Why does pressure drop increase during use?

A: This is usually caused by pulverization, impurity blockage, or uneven filling. The system needs to be checked or the adsorbent replaced.

Q: Is the product suitable for liquid drying?

A: Yes, 5A molecular sieves are commonly used for deep dehydration of solvents and liquid hydrocarbons.

Q: Is the molecular sieve hygroscopic?

A: Yes, molecular sieves are highly hygroscopic and should be used or resealed as soon as possible after opening.

Q: What is the minimum order quantity?

A: Usually, the minimum order quantity is 1 ton or 1 pallet, but this can be negotiated based on the order details.

Q: What is the typical delivery time?

A: Standard specifications are usually shipped within 7–15 days. Delivery times for large orders will be adjusted accordingly.

Q: Can you provide technical data sheets?

A: Yes, we can provide Technical Data Sheets (TDS), test reports, and application recommendations.
