Bactericidal filter layer for water pump and manufacturing process of bactericidal filter layer for water pump

Abstract

The invention belongs to the technical field of water pump filtration and sterilization and discloses a bactericidal filter layer for a water pump and a manufacturing process of the bactericidal filter layer for the water pump. The bactericidal filter layer comprises a filter layer and a bactericide uniformly scattered in the filter layer, and the bactericide comprises at least one of triclosan and sorbic acid. The elongation at break of the filter layer is 25-40%, and the density of the filter layer is 12.5-13kg / m<3>. The bactericidal filter layer for the water pump has efficacies of completely filtering tiny impurities such as dust in water and inhibiting growth of bacteria in water.

Description

technical field

[0001] The invention relates to the technical field of water pump filtration and sterilization, in particular to a sterilization filter layer for water pumps and a manufacturing process thereof. Background technique

[0002] Small water pumps with a power of 5w-20w are widely used, and are usually used in fish tanks, bonsai, special air conditioning water treatment systems, etc. However, the use environment of the small water pump will directly cause the accumulation of dust, foreign objects and other small impurities inside it, and if the water environment is not replaced for a long time, the phenomenon of bacteria, fungi and other microorganisms will multiply inside the small water pump, resulting in the life of the small water pump. Usually within a year.

[0003] When the above situation occurs in the small water pump, the traditional operation is to replace the small water pump. However, due to the special and complex design structure of the small wate...

Examples

Embodiment 1

[0041] Example 1: A sterilizing filter layer for a water pump, the elongation at break of the filter layer is 40%, and the density is 12.5kg / m 3 .

[0042] And the sterilization filter layer for water pump is prepared by the following steps:

[0043] Step 1, disperse and manufacture polyester fibers with a strength of 3.5 g / denier to obtain a filter layer;

[0044] In step 2, the bactericide and ethanol are fully mixed at a weight ratio of 1: 5-5.5 to form a bactericide mixed solution;

[0045] In step 3, the filter layer obtained in step 1 is immersed in the bactericide mixture obtained in step 2 according to the standard of adding 22-24L of the bactericide mixture to the filter layer per cubic meter, immersed for 5 minutes, and the filter layer is taken out. , fully dried to obtain a sterilization filter layer for water pumps.

[0046] Wherein, the bactericide is composed of dichlorophenoxychlorophenol and sorbic acid with a weight ratio of 2:1.

Embodiment 2

[0047] Example 2: A sterilizing filter layer for a water pump, the difference from Example 1 is that the strength of the polyester fiber is 5.5 g / denier, the elongation at break of the filter layer is 25%, and the density is 13 kg / m 3 .

Embodiment 3

[0048] Example 3: A sterilizing filter layer for a water pump, the difference from Example 1 is that the strength of the polyester fiber is 4 g / denier, the elongation at break of the filter layer is 35%, and the density is 12.8 kg / m 3 .
