Polyvinyl chloride modifications, properties, and applications: …
2022年3月5日 — The present study provides an overview of the latest scientific developments in the field of application and modification of ion exchange sorbents and membranes made of granular and powdery polyvinyl chloride (PVC), focusing on some scientific works, such as water and wastewater treatment, ion exchange, gas separation, etc.
Ion Exchange - GF Piping Systems
Ion exchange is the exchange of ions between two electrolytes or between an electrolyte solution and a complex. This process is widely used for purification, separation, and decontamination of aqueous and other ion-containing solutions. In a resin ion exchanger, a resin containing positive or negative ions absorbs unwanted ions into the water ...
Ion Exchange & Water Demineralization Handbook | Veolia
Rubber and polyvinyl chloride (PVC) are commonly used for ion exchange vessel linings. The controls and regenerant systems for demineralizers are more complex, to allow for such enhancements as stepwise acid and warm caustic regenerations.
Ion-exchange resin - Wikipedia
An ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange, that is also known as an ionex. [1] . It is an insoluble matrix (or support structure) normally in the form of small (0.25–1.43 mm radius) microbeads, usually white or yellowish, fabricated from an organic polymer substrate.
Preparation of Polyvinylchloride (PVC) Membranes, …
2021年9月24日 — Heterogeneous cation exchange PVC/CA blend membranes were fabricated by polymeric solution had cation exchange resin (Ion exchanger Amberlyst 15) with the treatment of prepared membrane by a solution of HCl and NaCl .
Preparation and characterization of PVC based heterogeneous ion ...
2013年5月25日 — For the purpose, polyvinylchloride (PVC)/styrene–butadiene-rubber (SBR) blend heterogeneous cation exchange membranes were prepared by solution casting techniques using cation exchange resin powder as functional groups agent and tetrahydrofuran as solvent.
Chambers are available in translucent PVC, PVC, or fiberglass rein- forced polyethylene shell, in sizes from 0.15 to 15 cubic feet of resin. Built-in strainers help prevent resin migration.
Characterization of poly(vinylchloride) (PVC) based cation exchange ...
2012年9月3日 — In this study, poly(vinylchloride) (PVC) based heterogenous strong acidic cation exchange membranes were prepared by the solution casting technique by using suspension polymerized polyvinylchloride (S-PVC) and emulsion polymerized polyvinylchloride (E-PVC) as binders, dioctyl phthalate (DOP) and ionic liquid (IL) tetradecyl(trihexyl ...
Ion Exchange Vessels - Newterra
Newterra’s Ion Exchange Vessels are designed for high-efficiency treatment of water and wastewater in industrial applications. These vessels utilize ion exchange resins to selectively remove contaminants such as heavy metals, hardness ions, and other dissolved solids, resulting in high-purity water suitable for various industrial processes.
Decomposition of PVC and Ion Exchange Resin in Supercritical …
Destruction condition and rate in the supercritical water were examined using Polyvinyl Chloride (PVC) and ion exchange resins as organic substances. The experiment was carried out at for 30min, which is relatively lower than the temperature for supercritical water oxidation .
