Abstract

The present invention discloses a hollow fiber membrane filtration core potting mold and a use method thereof. The potting mold is made from a hydrophobic organic material and has advantages of simple structure, easy processing and easy use, wherein the hydrophobic organic material has a low surface energy so as to effectively reduce the adhesion between the potting glue and the potting mold, such that the potted and casted filtration core can be completely demolded, the demolding difficulty is reduced, the damage on the work-piece during the demolding process is avoided, and the potting efficiency is effectively improved. According to the use method of the potting mold, with the pre-treatment process on the potting mold, the demolding difficulty is further reduced, and the potting efficiency is improved.

Description

technical field [0001] The invention relates to the field of manufacturing hollow fiber membrane filter cores, in particular to a hollow fiber membrane filter core potting mold and a use method thereof. Background technique [0002] Hollow fiber microfiltration / ultrafiltration membrane elements are the most widely used form of membrane technology. Generally, the hollow fiber microfiltration / ultrafiltration membrane element is composed of thousands of hollow fiber membrane filaments. There are micropores on the hollow fiber membrane, which allow solvents and substances smaller than the pore size to pass through, while retaining substances larger than the pore size. , so it is widely used in the field of drinking water purification. [0003] As the core component of the water purifier, the hollow fiber membrane filter element has the advantages of large specific surface area, high packing density, and easy cleaning compared with ceramic filter elements and activated carbon fi...
