The porous material has been widely used in many fields, such as the
main catalytic microporous molecular sieve material, adsorption and ion
exchange material separation materials plays an increasingly important
role in oil processing, petrochemicals, fine chemicals, and household
chemicals .
Molecular sieves (also known as a synthetic zeolite)
is a microporous aluminosilicate crystalline silicon. It is made of
silicon oxide, aluminum oxide tetrahedra basic skeleton structure, there
is a metal cation in the crystal lattice (such as Na +, K +, Ca2 +, Li
+, etc.), in order to balance the negative charge excess crystals.
According to their type of zeolite crystal structure is divided into: A
type, X-type, Y type.
Zeolite relevant standards:
"3a molecular sieve" "4A molecular sieve" "5a molecular sieve and test methods" "13X molecular sieve"
"Water assay method static sieve" "sieve dynamic water assay method"
"Granular
sieve size determination," "Determination of bulk density of molecular
sieve" "sieve crush strength test method", "Standard Test Method for
molecular sieve desiccant cooling systems with anti-wear performance,"
"Determination of dynamic zeolite adsorption of carbon dioxide."
"Industrial activated alumina," "air separation plant with activated alumina acceptance technical conditions"
(5) Pharmaceutical ---- silver zeolite antimicrobial agent.
