Problems solved by technology

This kind of filter element not only has a dense and uniform pore size formed on the surface, but also effectively overcomes the problems of the precipitation of the filter medium and the desorption of impurities during the filtration process, and after the water-based adhesive is evaporated and dried by water, the remaining component is silicon dioxide. , silica itself also has a certain purification effect on the water body, and there is no problem of adhesive blocking the micropores of the filter medium, which greatly improves the overall filtering effect of the filter element and ensures the safety of the water outlet. At the same time, the production cost of the water-based adhesive is low and safe. ,Environmental friendly

Abstract

The invention relates to a filter element, in particular to a filter element for filtration and a manufacturing method thereof. In the preparation process of the filter element, various raw materials are weighed according to percentage by weight in a formula, adding materials according to specified steps and then mixing and stirring evenly, extruding or punching for shaping in a preset mould, drying the water in the model at a certain temperature for sizing, namely forming the porous filter element with specified shape. The filter element of the invention utilizes various non-toxic and harmless raw materials with absorption characteristics, is formed by bonding water-borne adhesive, has the characteristics that the usage of a filter material in unit volume is large, the adsorption efficiency is high, the finished filter element after adsorption and saturation can regenerate under the condition of high temperature while the original physicochemical property of the filter element is not changed, the surface of the filter element after being jammed by absorbing and stopping sundries can be polished by sand paper and reused, and the like; in addition, the cost for manufacturing the water-borne adhesive is low and the raw materials are safe and environmental friendly.

Description

technical field [0001] The invention relates to a filter element, in particular to a filter element for filtering and a manufacturing method thereof. Background technique [0002] At present, with the intensification of environmental pollution, more and more wanton discharge of industrial wastewater and domestic wastewater and the extensive use of pesticides and fertilizers in agriculture have seriously damaged my country's water resources and caused many harmful substances in the water , Threatening people's lives, drinking safe water has become a problem that consumers pay close attention to, and water purifiers are developed under such circumstances. [0003] At this stage, the filter elements used in water purifiers to purify drinking water mainly include PP cotton, ceramics, ion exchange resins, ultrafiltration membranes, R0 reverse osmosis membranes, and activated carbon. PP cotton is mainly used to filter the most basic impurities such as rust, sediment and some collo...
