preparation example Construction

[0041] Wherein, a kind of preparation method of konjac glucomannan membrane mask filter element, based on above-mentioned konjac glucomannan membrane mask filter element, comprises the following steps,

[0042] To prepare the glucomannan paper fiber wave film layer 1, add 3.1 to 3.3 parts of paper fiber to 95 to 97 parts of pure water and stir evenly, then add 0.48 to 0.50 parts of anhydrous sodium carbonate and anhydrous sodium carbonate After dissolving, add 1 to 2 parts of konjac gum, stir with a magnetic stirrer at 300rpm for 60 to 90 minutes to obtain a mixed solution; then spread the mixed solution on a glass plate and place it at room temperature for 10 to 20 hours, then place the glass plate on Heating in an induction cooker at a high temperature for 15 to 20 minutes to obtain a film, and then roll forming the film so that the cross section of the film is wavy to obtain a wavy film layer 1 of konjac glucomannan paper fiber with a thickness of 0.3 to 0.8 mm; wherein, Th...

Embodiment 1

[0055] according to figure 1 As shown, the present embodiment provides a kind of preparation method of konjac glucomannan membrane mask filter element, comprising the following steps:

[0056] To prepare glucomannan paper fiber wave film layer 1, add 3 parts of paper fiber to 96 parts of pure water and stir evenly, then add 0.48 parts of anhydrous sodium carbonate, after the anhydrous sodium carbonate dissolves, add 1 part of Konjac gum was stirred with a magnetic stirrer at 300rpm for 60 minutes to obtain a mixed solution; then the mixed solution was spread on a glass plate, placed at room temperature for 20 hours, and then the glass plate was placed in an induction cooker and heated at a high temperature for 20 minutes to obtain a film, and then the The film is rolled and formed so that the cross section of the film is wavy, and after being cooled, it is placed in the refrigerator to freeze to obtain a konjac glucomannan paper fiber wave film layer 1 with a thickness of 0.3m...

Embodiment 2

[0069] according to figure 1 As shown, the present embodiment provides a kind of preparation method of konjac glucomannan membrane mask filter element, comprising the following steps:

[0070] To prepare the glucomannan paper fiber wave film layer 1, add 3.2 parts of paper fibers to 96 parts of pure water and stir evenly, then add 0.48 parts of anhydrous sodium carbonate, after the anhydrous sodium carbonate dissolves, add 2 parts Konjac gum was stirred with a magnetic stirrer at 300rpm for 90min to obtain a mixed solution; then the mixed solution was spread on a glass plate and placed at room temperature for 15 hours, then the glass plate was placed in an induction cooker pot and heated at a high temperature for 15min to obtain a film, and then the The film is rolled and formed so that the cross section of the film is wavy, and after cooling, it is placed in the refrigerator to freeze, and the konjac glucomannan paper fiber wave film layer 1 with a thickness of 0.8mm is obtai...

Abstract

The invention provides a konjac glucomannan film mask filter element and a preparation method thereof. The konjac glucomannan film mask filter element comprises a glucomannan paper fiber wave film layer used for coarse filtration, a konjac glucomannan activated carbon sponge layer used for adsorption and deodorization, a konjac glucomannan silver-loaded nano film layer used for antibiosis and efficient filtration and a konjac glucomannan paper fiber film layer. The adopted raw material konjac glucomannan is a natural degradable biological material, the paper fiber is also degradable, if the prepared composite mask filter element is buried in a soil layer for 2-3 months, the degradation rate can reach 91%, and the composite mask filter element is an environment-friendly composite mask chip; coconut shell activated carbon is a high-quality adsorption material, the adsorption principle is physical adsorption, and no pollution is caused to the environment; the nano-silver has a certain antibacterial ability and can effectively inhibit bacterium breeding.

Description

technical field [0001] The invention relates to the technical field of sanitary products, in particular to a konjac glucomannan membrane mask filter element and a preparation method thereof. Background technique [0002] With the development of economy, people's living environment is seriously polluted, and the air people breathe is also polluted. Haze is a general expression of the excessive content of various suspended particulate matter in the atmosphere, especially PM2.5 (particulate matter with an aerodynamic equivalent diameter less than or equal to 2.5 microns). , It is easy to enter the alveoli and then enter the blood, interfere with the gas exchange in the lungs, and cause diseases such as asthma, bronchitis and cardiovascular disease. When people work in an environment with dust, toxic gas, and odor, it will also cause harm to the human body. To prevent haze weather, dust, toxic gas, and odor from causing harm to the human body, wearing an anti-haze mask is the s...
