3A molecular sieve,sometimes also known as 3A zeolite molecular sieve,is a kind of potassium-sodium aluminosilicate with LTA-type skeleton structure which is composed of silicon-oxygen and aluminum-oxygen tetrahedrons.The main crystal hole of the 3A molecular sieve is an eight-membered ring structure, and the crystal pore size is 3Å (0.3nm).This kind of Molecular Sieve is mainly used to adsorb water, and does not adsorb any molecule with a diameter larger than 3A. According to the characteristics of industrial applications, the molecular sieve 3A produced by Fulong has faster adsorption speed, more regeneration times, higher crushing strength and stronger wear resistance,which greatly improves the utilization efficiency of molecular sieves and prolongs the service life of molecular sieves. It is the first choice desiccant necessary for deep drying,refining and polymerization of gas and liquid phases in petroleum and chemical industries.3A molecular sieves are usually used in ethylene, propylene, butadiene, methanol, ethanol, natural gas, cracked gas, refrigerant dehydration, etc.
Formic acid,also known as Methanoic Acid,is a colorless transparent smoky liquid with a pungent odor at room temperature. It is the simplest carboxylic acid with strong Corrosiveness.Formic acid is one of the basic organic chemical raw materials, widely used in pesticide, leather, dye, medicine and rubber industries. Formic acid can be directly used in fabric processing, leather tanning, textile printing and dyeing and green fodder storage, and can also be used as metal surface treatment agent, rubber auxiliary and industrial solvent. Used in the synthesis of various formic acid esters, acridine dyes and formamide series pharmaceutical intermediates in organic synthesis.
Methyl hexahydrophthalic anhydride also known as MHHPA,is a colorless liquid anhydride hardener produced from methyl tetrahydrophthalic anhydride (MTHPA) through the catalytic hydrogenation process. It is often used in the epoxy curing related fileds that has higher requrement for the color, the weather resistance,moisture resistance and heat resistance.
Pentaerythritol also known as Monopentaerythritol and tetramethylolmethane,is an organic compound with the formula C(CH2OH)4. Classified as a polyol, it is a white solid. Pentaerythritol is a building block for the synthesis and production of explosives, plastics, paints, appliances, cosmetics, and many other commercial products.
