dowex macroporous resin - Introduction
product technical standard: GB/T 16579-1996 DL 519-93 SH 2605.02-1997
The performance of this product is similar to that of 001 × 7 strong acidic cation exchange resin, but it has better physical and chemical stability (resistance to permeation pressure, wear resistance, etc.) and better oxidation resistance. Due to its macroporous structure, this product can be used to adsorb impurities with larger molecular weight and use in non-aqueous media. This product is equivalent to Amberlite IRA-200 in the United States, Lewatit-sp120 in Germany, Diaion PK in Japan, Zerolite S-1104 in the United Kingdom, Allassion in France and Ky-2-12P in the former Soviet Union, and is equivalent to the old brand D031 in China. No. 61; No. 72; D1099;744.
Usage: This product is mainly used for the preparation of high-purity water (especially for high-speed mixed beds) and for condensate purification devices (H-OH or
MH4-OH mixed bed system), but also
Used for wastewater treatment, recovery of heavy metals; amino acid recovery; also used as a catalyst.
Packing: woven bag lined with plastic bag. Plastic bucket lined with plastic bag.
