preparation example Construction

[0040] The present invention provides a kind of fibrous filter membrane and its preparation method, and accompanying drawing is illustrated in the specific embodiment of the present invention and its components, all about front and back, left and right, top and bottom, upper and lower, and horizontal and vertical The references are for convenience of description only, and do not limit the present invention, nor limit its components to any position or spatial orientation. The dimensions specified in the drawings and description can be changed according to the design and requirements of the specific embodiments of the present invention without departing from the patent protection scope of the present invention.

[0041] Regarding the fiber filter membrane of the present invention and its preparation method, wherein the fiber filter membrane uses fine powder particles containing sialic acid or its derivatives, added to the binder chitosan to spray, impregnate, coat and chemically ...

Embodiment 2

[0052] Example 2 Evaluation of desorption rate

[0053] First, the fiber membrane samples were dried and weighed. The fiber membrane sample was placed in a beaker, 100ml of secondary water was added, and stirred with a magnetic stirring bar for 6 hours. The secondary water before and after stirring can be tested with an Austrian viscometer to understand whether the binder is stirred and released into the secondary water to cause changes in viscosity properties. image 3 It is the test result of the desorption rate of the energy stone composite fiber. Here, an Austrian viscometer is used to test whether the sialic acid derivatives are firmly attached to the kinetic stone composite fibers. Taking the viscosity residence time (seconds) of the secondary water as the correction group, if the sialic acid derivative and the binder chitosan are released into the secondary water due to poor firm fixation, the viscosity residence time will be increased. image 3 The results showed th...

Embodiment 3

[0054] Embodiment 3 evaluates the water body hydrogen ion concentration (pH value) and oxidation-reduction potential (ORP) test after passing through the fiber filter membrane

[0055] The water body is introduced into the above-made fiber filter membrane, and after passing through the fiber filter membrane, the water body is collected. The pH and ORP probes (Broadley-James Corporation, Irvine, California, USA) were used to analyze the hydrogen ion concentration and oxidation-reduction potential of the water before and after passing through the fiber membrane with a pH meter (HI8014, HANNA Instruments, Romania). Table 1 shows the test results of the tap water collected after passing through the composite fiber of the activated stone and the zeolite. After tap water passes through the kinetic stone composite fiber of the present invention, its oxidation-reduction potential value drops from 568mV to 343-399mV. In addition, after tap water passes through the zeolite composite fi...

Abstract

The present invention relates to a fiber filtration membrane and a preparation method thereof. According to the present invention, composite fibers are adopted as the fiber main structure, and spraying, impregnation, coating, chemical grafting or ultrasonic vibration embedding and other ways are used to fix sialic acid or a derivative thereof on the fiber surface with an adhesion material chitosan and strengthen with a cross-linking agent; the composite fibers adopts a porous non-woven fabric as the main structure, has a plurality of filtration pores, can produce far infrared rays and anti-oxidation capacity, and further has the multi-effect filtration capability, wherein the raw water body can produce the reducing water having the anti-oxidation capability after passing through the special fiber filtration membrane; with the fiber filtration membrane and the multiple pores formed through the preparation method, impurity particles in gas or fluids can be effectively filtered out so as to achieve the multi-effect filtration effect, wherein the impurity particles comprise heavy metals, residual chlorine, lipopolysaccharide, microcystin, and the like; and the structure can be widely used in the fields of fluids or gases, drinking, bathing, environmental sewage treatment, and medicine.

Description

technical field [0001] The invention relates to a filter membrane for filtering raw water, in particular to a fiber filter membrane and a preparation method thereof. Background technique [0002] Water is an indispensable substance for all living organisms. Taking the human body as an example, about 70% of the human body is water, and each person needs to consume about 3% of their body weight in water every day. Therefore, it can be seen that the quality of environmental water is closely related to national health. In view of this, water purifiers and other related products have sprung up around our lives. There are many types of water purifiers, and the more well-known ones include activated carbon water purifiers, reverse osmosis water purification systems, cation exchange resin water softeners, ultraviolet light sterilization and ozone sterilization water purifiers, etc. However, the filter element is the core device that really plays a key role. In addition, the mater...
