Ion exchange resin filling method for space product

Abstract

The invention discloses an ion exchange resin filling method for a space product. The ion exchange resin filling method comprises the following steps: 1, implementing preparation before production; 2,cleaning ion exchange resin; 3, cleaning and drying an ion exchanger; 4, putting the ion exchange resin into the ion exchanger, and placing the ion exchange on a power frequency vibration platform soas to obtain an ion exchanger filled with the ion exchange resin in a vibration manner; 5, performing sealed packaging on the ion exchanger; 6, performing vacuum exhausting on the ion exchange so asto obtain a filled ion exchange; 7, testing the filled ion exchange, thereby obtaining a qualified ion exchange. By adopting a filling method of vibration filling+vacuum injection exhausting, the amount of filled ion exchange resin is numeralized, the filling density of the ion exchange resin is maximized, the air among resin granules is effectively discharged, the influence of the air to the exchange efficiency of the ion exchange resin is reduced, and the service life of the whole ion exchange is prolonged.

Description

technical field [0001] The invention relates to the technical field of ion exchange resin filling, in particular to an ion exchange resin filling method for space products. Background technique [0002] Ion exchange resins are polybasic acids or bases with high molecular weight, which are insoluble in most aqueous and non-aqueous media. Their structure can be regarded as a sponge body containing large polar exchange groups, and such groups are united through a three-dimensional carbon network structure. In ion exchange resins, an ionic group is usually fixed in the network structure of the polymer, so it becomes an insoluble or immobile solid phase. Ions of opposite charge are mobile and can exchange, or "swap," with other ions in the surrounding solution. Ion exchange resins are widely used in water softening, desalination, wastewater treatment, precious metal enrichment and separation, nuclear industry, catalysis, and medicine. The use of ion exchange resins is preferre...
