Reproducibility
It can be reused by raising the temperature of the recycled gas by purging or heating and vacuuming.(The dehydration efficiency of the regenerated molecular sieve is related to the regeneration temperature)
Packinginstructions
25kg carton ordinary packaging, cardboard drum or iron drum seal, lined with two layers of plastic woven bags.
Matters needing attention
Molecular sieve moisture absorption, storage is not easy to be directly exposed to the air, should be placed in a dry place, such as adsorption function failure, can be regenerative treatment,its performance unchanged.
Regeneration temperature below 350℃ is appropriate, should not exceed 600℃
Do not contact water, oil, acid and alkali substances.
