Storage life of unused ion exchange resin under appropriate conditions Under appropriate conditions: store in a dry, cool and unopened package at 5-30℃

Seplite® LSC285 special resin for brine iodine removal, and developed a complete set of iodine removal process through the industrial scale verification of many domestic ion membrane caustic soda productionenterprises, the effect is remarkable. The iodine is effectively removed and the iodine recoveryis realized. It not only solves the problem of electricity efficiency, but also creates economic benefits, which is highly praised and recommended by industry and enterprises.

Sunresin participated in the Expo as scheduled and brought four series of resin products and technologies themed as "metal recovery", "waste gas adsorption", "waste water treatment" and "special standard raising", which made the environmental protection treatment more targeted.

The color indicator resin is introduced into gel type anion or cation exchange resin through a special process, which makes the color changes under different ion types. It is convenient for users to judge the exhaustion state of ion exchange resin directly.

Chromatographic separation is an effective method for separating components in complex mixtures, which is based on different partition coefficients of different substances in stationary phase and mobile phase. When the two phases move in relative motion, these substances move together with the mobile phase and are distributed repeatedly between the two phases. Thus, different substances are eluted at different places and separation is achieved.

The performance of ion exchange resin is affected by many factors. If abnormal performance degradation of ion exchange resin occurs in daily use, we generally carry out the cause analysis and take corresponding measures according to the following sequence.

The strong base anion exchange resin contains a certain amount of moisture and should not be stored in the open air. During the storage and transportation, it should be kept moist to avoid air drying and dehydration, which will cause the resin to break. If dehydrated during the storage, the resin should be soaked in concentrated salt water (25%) and then gradually diluted. Do not put the resin into water directly in case of rapid expansion and breakage.

Sunresin has selected professional R&D and production personnel to form a technical team to adjust and optimize the resin synthesis process, and has successfully developed a new generation of high exchange-capacity styrene series macroporous strong acid cation exchange resin Seplite® LSF971 Imporve and high exchange-capacity styrene type macroporous weak base anion exchange resin Seplite® LSF973 Imporve. Special matrix white balls synthesis process design optimizes the molecular framework and pore structure. At the same time in the ascension of exchange capacity of the resin, resin strength and service life also has improved. After industrial verification, the above two resins have significantly improved the material liquid treatment c1apacity compared with the conventional Seplite® LSF971 and Seplite® LSF973 resins, and the unit consumption of water and acid-base reagents during the operation of the resin is significantly reduced. With the high praise of many manufacturers in the industry, Sunresin's new generation of high exchange-capacitySeplite® LSF971 Imporve with Seplite® LSF973 Imporve resin will bring a cost revolution to the production of biodigesters.
