For acid-base desorption in an ion exchange resin tower at room temperature, is it better to use a rubber-lined or a plastic-lined structure? Can a sight glass be installed on it? Has anyone who has used it answered? Thank you!

Either one will do; investments don’t save that much money anyway

Which one is more durable or easier to work with?

The selection of the lining for an ion exchange resin column usually depends on the type of liquid being treated, the temperature, and the concentration. Generally speaking, rubber lining and plastic lining each have their advantages. The main advantage of rubber linings (usually made of rubber) is their good alkali and corrosion resistance, which allows them to perform well when handling acidic or alkaline solutions. Additionally, the rubber lining has good resistance to impact and mechanical damage. The main advantage of lining with plastics (usually PE, PP, PVC, etc.) is its good acid resistance, oxidation resistance, and aging resistance; however, its performance may decline in high-temperature environments. Generally speaking, plastic linings perform well with most organic solvents and oils. Regarding the issue of sight glasses, ion exchange resin towers usually have sight glasses installed to enable operators to conduct observations easily. However, the setup of the viewports must comply with relevant safety regulations, and the materials used must be able to withstand the chemicals and temperatures present in the operating environment. The information above is for reference only; specific decisions should be based on your individual circumstances and needs. If possible, it is recommended to seek evaluation and guidance from professionals. .

Generally, rubber lining is used for things such as anion and cation beds, resin cleaning tanks, and pipelines, allowing glass viewports to be used to observe the resin and its level. It should be noted that the lining of newly installed equipment and prefabricated pipes is best carried out in factories with experience and quality assurance; on-site fabrication may lead to delamination due to sulfonation and environmental factors. (Manufacturers of water treatment equipment all have their own partners; after the lining is applied, the equipment is taken to the site.) I’ve never used nor seen tanks with plastic linings; when plastic-lined pipes are used to transport dilute acids, bulging can occur inside them at higher temperatures.
