Diaion SK-IAPrecautionsResin should be wet
state preservation. The best temperature is above 0ºC. Resin should
be put into a closed space or add in salt water of 5% or above if
not used for a long time.Should be anti-freezing during
transportation. Do not place heavy objects on the resin in case
being crashed.Generally requires alkali- water - acid - water flow
path for processing. Strict requirement needs three circulation
before coming to final ion kenel.Need to consider different
transformation expansion rate to set aside enough space to prevent
resin overflow and ensure the appropriate liquid level height;
Column diameter ratio should be within a reasonable range and avoid
bias current; Use wet packed column or back-flushing to wash away
bubbles inside resin layer.Before liquid going into the resin
column, steps as flocculation, filtration, or sand-filtration
should be taken so that it doesn't jam resin pore with suspended
solids .Resin inside the column that hasn't been used for a long
time should be storaged outside of the column after washing, or
adding salt water in the salt resistant medium while keeping liquid
level not dehydrated with usual backwashing to loosen resin in case
of agglomeration.IndexnameSpecificationAppearancePale yellow clear
