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 ...
