The main roles of adding molecular sieves in polyurea waterproof coating are as follows:Removing moisture and impurities:Molecular sieves can adsorb moisture and impurities in the coating, reducing their negative impact on the coating’s performance. This improves application performance, weather res

I. Raw material preparation and pretreatmentBefore the molecular sieve dehydration treatment, the biopharmaceutical raw materials need to be fully prepared and pretreated. The raw materials should meet the specified purity and quality standards to ensure that there are no impurities and pollution. T

Compared with traditional activated alumina, Chemxin activated alumina (AA) has a surface area more than 20% higher, static water adsorption rate ≥ 20%, and laboratory dynamic water adsorption rate ≥ 18%. At the same time, the average regeneration heat of desorption of AA is relatively small when ad

What is the air separation unit?Air Separation Unit (ASU) is a complex system used to separate oxygen, nitrogen, argon and other inert gases from air. This process is mainly based on the different boiling points of the components in the air, and is realized by physical methods (e.g., compression, co
