Embodiment 1

[0038] Choose a piece of non-woven fabric;

[0039] Control the air pressure in the vacuum chamber at 6×10 -6Torr, when the non-woven fabric reaches the sputtering chamber, fill the sputtering chamber with argon gas at a flow rate of 1mtorr / min, and start the DC power supply to supply a DC power supply with a power of 5Kw to the magnetron sputtering target to form argon gas Plasma: The silver atoms on the silver target are splashed out by the plasma bombardment, and deposited on one surface of the non-woven fabric to form a nano-scale silver film. The aforementioned predetermined power is controlled at 0.5w / cm in the power density value of the silver target (electrical power / area of ​​the surface of the silver target bombarded by the plasma) 2 ~25w / cm 2 between, so that the thickness of the formed nano-silver is between 20 and 40 nanometers (the silver film is formed by stacking silver atoms on the surface of the non-woven fabric one by one), because at this scale, it can ha...

Embodiment 2

[0041] Choose a piece of non-woven fabric;

[0042] Control the air pressure in the vacuum chamber at 10×10 -6 Torr, when the non-woven fabric reaches the sputtering chamber, fill the sputtering chamber with argon gas with a flow rate of 10mtorr / min, start the DC power supply, and supply a DC power supply with a power of 20Kw to the magnetron sputtering target to form argon gas Plasma: The silver atoms on the silver target are splashed out by the plasma bombardment, and deposited on one surface of the non-woven fabric to form a nano-scale silver film. The aforementioned predetermined power is controlled at 0.5w / cm in the power density value of the silver target (electrical power / area of ​​the surface of the silver target bombarded by the plasma) 2 ~25w / cm 2 between, so that the thickness of the formed nano-silver is between 30 and 40 nanometers (the silver film is formed by stacking silver atoms on the surface of the non-woven fabric one by one), because at this scale, it ca...

Embodiment 3

[0044] Choose a piece of non-woven fabric;

[0045] Control the air pressure in the vacuum chamber at 8×10 -6 Torr, when the non-woven fabric reaches the sputtering chamber, fill the sputtering chamber with argon gas at a flow rate of 20mtorr / min, and start the DC power supply to supply a DC power supply with a power of 15Kw to the magnetron sputtering target to form argon gas Plasma: The silver atoms on the silver target are splashed out by the plasma bombardment, and deposited on one surface of the non-woven fabric to form a nano-scale silver film. The aforementioned predetermined power is controlled at 0.5w / cm in the power density value of the silver target (electrical power / area of ​​the surface of the silver target bombarded by the plasma) 2 ~25w / cm 2 between, so that the thickness of the nano-silver formed is between 35 and 40 nanometers (the silver film is formed by stacking silver atoms on the surface of the non-woven fabric one by one), because at this scale, it can...

Abstract

The invention discloses a nano argentums nonwoven cloth and its application on filter cartridge, specially to a filter cartridge which uses a high-technology industry used splash plating equipment to splash and plate a nano grade argentum thin film with bacterium suppressing effect on the nonwoven cloth, applies it on the filter cartridge products and contains the nano argentum nonwoven cloth. The filter cartridge has a hollow pole shaped body, includes a filtering material protection layer, an absorbent charcoal part, a rubber glue cover, a rubber cushion and a telescopic meshwork, wherein, the nano argentum nonwoven cloth produced by the method is coated between the absorbent charcoal part and the telescopic meshwork. The produced filter cartridge has the function of clearing away peculiar smell, coloring matter and aquatic chlorine and antimicrobial function (with an antimicrobial rate above 99.9%), thereby the use is safe and reliable, the drinking water quality is greatly improved, and the water gives prodigious help to the health of human body.

Description

technical field [0001] The invention relates to nano-silver non-woven fabric and its application on a sterilizing filter element, specifically, a nano-scale silver film with antibacterial effect is sputtered on a non-woven fabric by sputtering equipment used in high-tech industries, and the It is applied to filter element products. Background technique [0002] The origin of antibacterial materials has been used since ancient times. People found that the water kept in silver and copper containers should not deteriorate. Silver has long been recognized as having an antibacterial effect. Even so, until now, scientists know very little about its bactericidal mechanism. Generally speaking, they all achieve the purpose of sterilization by destroying the enzyme (a protein) used by bacteria to deliver nutrients, or weakening the cell membrane wall or cytoplasm function of bacteria. For example, silver particles act as catalysts for oxidation reactions that disrupt the -SH bonds ...
