Problems solved by technology

In actual use, the main purification and interception functions are the second-stage filter element and the third-stage filter element, and the replacement cycle of the second-stage filter element and the third-stage filter element is short and expensive, and the second-stage and third-stage filter elements are frequently replaced. It will lead to high cost of water purification equipment, which will make water purification equipment unacceptable by consumers

Embodiment Construction

[0030] In order to make it easy to understand the technical means, creation features, achieved goals and effects of the present invention, the present invention will be further described below with reference to the specific figures.

[0031] A preparation method of a high-efficiency filter element for water purification equipment, comprising the following steps:

[0032] 1) The polymer is used to form an initial melt-blown fiber web through a melt-blown process, the temperature of the cooling airflow is increased during the preparation of the initial melt-blown fiber web, and the melt-blown primary fibers are insufficiently cooled to obtain an initial melt-blown fiber web with a surface maintaining melt-adhesiveness. Spray fiber mesh.

[0033] In the prior art, under normal circumstances, in the preparation process of the melt-blown nonwoven fiber web, it is necessary to sufficiently cool the spun fibers from melt spinning to rapidly solidify them into a fiber form and form a ...

Abstract

The invention belongs to the field of preparation of non-woven materials, and relates to a high-efficiency filter element of water purification equipment and a preparation method of the high-efficiency filter element. A melt-blown fiber web is modified twice by adopting solid powder modified particles, wherein the solid powder modified particles applied in the first modification are mainly distributed on the surface of the melt-blown fiber web; solid powder modified particles applied in the second modification are mainly distributed in the middle of the melt-blown fiber web, and through two times of modification treatment, the surface and the inner core of the finally obtained melt-blown fiber web both have proper content of solid modified particles; certain adhesion is further preserved on the surface of the melt-blown fiber web in the first modification process, the adhesion firmness of solid powder modified particles and fibers is improved by means of a fluidized bed spraying device with relatively high solid powder spraying capacity, the solid powder modified particles are not prone to falling off, the frequency of replacing a filter element is reduced, and the use cost of water purification equipment is lowered.

Description

technical field [0001] The invention belongs to the field of non-woven material preparation, in particular to a high-efficiency filter element for water purification equipment and a preparation method thereof. Background technique [0002] As people's hygiene requirements for drinking water are getting higher and higher, water purifiers are used more and more widely in various occasions (such as homes, businesses and some entertainment venues, etc.), traditional reverse osmosis water purifiers need to be assembled before The filter element assembly is generally a filter bottle with a filter element, or a filter bottle with multiple pre-filter elements. [0003] Chinese patent CN201911224557 discloses a high-flux four-in-one filter element structure, including a filter bottle, a filter bottle cap, a water guide cylinder, a PP composite filter element, a reverse osmosis filter element, a PP upper end cap and a PP lower end cap. There are raw water inlet, booster pump water in...
