PRODUCT DESCRIPTION

ZGA  304  is  a  Type  Ⅰ  strongly  base  anion  exchange  resin  with  quarternary ammonium structure bease on polystryrene. It has excellent regeneration efficiency and rinse characteristics. The resin has exceptional physical and chemical stability. It also shows good kinetics of exchange, producing very low concentration levels of both strong and weak acid anions to be achieved at practical flowrate. The resin is supplied in chloride or hydroxide form.

ZGA 304 is mainly used in production of pure and ultra-pure water, decoloration for sugar, separation and purification of biochemicals and radio-elements.

FEATURES & BENEFITS

● FINE PARTICLE SIZE

95% all beads are in the assignation range; giving a lower pressure drop and superior kinetics.

● SUPERIOR CHEMICAL AND PHYSICAL STABILITY

Over 93% sphericity combined with high crush strengths and uniform particle size provide greater resistance to bead breakage resulting in longer service life and lower pressure drop.

● ORGANIC FOULING RESISTANCE AND HIGH OPERATING CAPACITY                     The highly porous structure of ZGA 304 allows greater removal and elution of

large organic molecules. High total capacity results in high operating capacity during demineralization.

ITS PHYCIAL & CHEMICAL PROPERTIES

CHEMICAL AND PHYSICAL STABILITY

ZGA  304  is  a  porous  gel  structure  of  copolymer  of  styrene  and  DVB  with quaternary  ammonium  group.  It  has  superior  kinetics  characteristic  and  highest regenerable   operating   capacity   of  the   typeⅠanion   exchange   resin   for   use   in

deionization and mixed beds. Especially, it has good resistance to organic fouling. The resin  has  good  bead  strength  and  excellent  integrity,  a  minimum  of  95%.  It demonstrates a high resistance to attrition from all stresses, physical, thermal and osmotic. Usually it has a longer service life. However, exposure to significant amounts of free chlorine, hypochlorite ions, or other strong oxidizing agents over a period of time will degrade the resin and break down the crosslinking. This can reduce the ion exchange  capacity or  increase the  moisture  retention  of the  resin, decreasing  its mechanical strength, and should be avoided. The resin in the hydroxide form under alkaline conditions will break down at temperatures over about 70℃ . The quaternary ammonium group losses the nitrogen and becomes weak base groups. The salt forms of the resin are at least more stable, but can still break down at higher temperatures with loss of strong base capacity.

APPLICATIONS

ZGA  304  is  widely  used  in  multiple  and  mixed  bed  demineralizers,  wherever remove anions and organic substances. It is importance for the production of pure water and ultra high quality water. ZGA 304 in hydroxide form is an effective way of providing low hardness water for medium pressure boilers.

It also  can  be  used  in separation and  purification  of biomedical  products and biochemicals. It can extract radioactive elements and decolour cane and corn syrup. The resin is also used in pharmaceutical industry.
