SBA resins contain quaternary ammonium groups and function across the entire pH range, removing both strong and weak acid anions. WBA resins contain primary/secondary/tertiary amines and only function in neutral to alkaline conditions, primarily removing strong mineral acids.
Resin should be kept in a wet state, ideally above 0°C. For long-term storage, place in a closed space or add a salt solution of 5% or higher to prevent dehydration and agglomeration.
Yes, our resins are produced in compliance with FDA, WQA, and ISO9001 standards, making them suitable for food-grade decolorization and pharmaceutical-grade protein purification.
The typical regeneration process involves 2BV of 3-5% HCl followed by 2BV of 2-4% NaOH, ensuring the resin is restored to its optimal exchange capacity.
Exposure to oxidants like chlorine or ozone can cause functional group loss. Lijiang's optimized crosslinking density ensures the resin maintains capacity and mechanical strength even in high-redox environments.
To prevent clogging of resin pores, it is essential to implement pre-treatment steps such as flocculation, filtration, or sand-filtration to remove suspended solids.
