1、 Shanghai 201x7strongly alkalineyinIon exchange resin manufacturerExecution standard: GB13660-92

This product is an ion exchange resin with a quaternary amino group [- N (CH3) 3] on a polymer matrix of styrene ethylene benzene copolymer crosslinking structure. Its alkalinity is equivalent to that of a general quaternary amine base, and it exhibits ion exchange function in acidic, neutral, and even alkaline media. This product has the characteristics of good structural strength and high heat resistance.
The original brand of this product is 717 #, which is equivalent to the foreign brand, Amberlite IRA-400 in the United States; Japan: Diaion SA-10A.
