Problems solved by technology

However, carbon rods are a hotbed for bacteria to grow easily. Therefore, running tap water through carbon rods can remove residual chlorine and organic pollutants, but at the same time it may increase the number of bacterial colonies in the water.

preparation example Construction

[0020] The preparation method of multiple antibacterial activated carbon sticks for said water purification comprises the following steps:

[0021] 1) Prepare activated carbon rod body A1; mix activated carbon powder, binder and antibacterial agent, and then shape it into activated carbon rod body A1; the molding method can be extrusion method or sintering method; the antibacterial agent can be selected from Silver zeolite, glass-based silver-loaded antibacterial agent or KDF, etc.; the specific steps of the extrusion method can be: feeding activated carbon powder, binder and antibacterial agent mixture into a single-screw extruder to form a carbon rod, extruding The temperature can be 160-220°C; the specific steps of the sintering method can be: fill the mixture of activated carbon powder, binder and antibacterial agent into the mold, place it in an oven and sinter it into a carbon rod, and the sintering temperature can be 240-240°C. 300°C.

[0022] 2) Prepare the antibacter...

Embodiment 1

[0025] Example 1: Soak the activated carbon stick without antibacterial agent in pure water for 3 days at room temperature, and test the number of colonies and the content of copper, silver and zinc ions in the water before and after soaking. This is a control experiment. The test results are shown in Table 1.

Embodiment 2

[0026] Embodiment 2: Preparation of activated carbon sticks comprising the combination of antibacterial protection measures A1 and A2 in the present invention. Soak it in pure water for 3 days at room temperature, and test the number of colonies and the content of copper, silver and zinc ions in the water before and after soaking. The test results are shown in Table 1.

Abstract

The invention relates to an active carbon rod, and discloses a multi-antibacterial active carbon rod for purifying water and a preparation method of the carbon rod. The multi-antibacterial active carbon rod can search an optimal safety point between an antibacterial effect and antibacterial agent exudation. The multi-antibacterial active carbon rod for purifying the water is provided with an active carbon rod body; an antibacterial screen cylinder is placed into an inner cavity of the active carbon rod body; an antibacterial melt-blown cotton layer is arranged on the external surface of the active carbon rod body; and an antibacterial LDPE (low-density polyethylene) grid layer is arranged on the external surface of the antibacterial melt-blown cotton layer. The preparation method comprises the steps that the active carbon rod body is prepared; active carbon powder, an adhesive agent and an antibacterial agent are mixed and then formed into the active carbon rod body; the antibacterial screen cylinder is prepared and then placed into the inner cavity of the active carbon rod body; the antibacterial melt-blown cotton layer is prepared and wound on the surface of the active carbon rod body; the antibacterial LDPE grid layer coating the antibacterial melt-blown cotton layer is prepared; and then the multi-antibacterial active carbon rod for purifying the water is obtained.

Description

technical field [0001] The invention relates to an activated carbon rod, in particular to a highly safe multi-antibacterial activated carbon rod for water purification and a preparation method thereof. Background technique [0002] Activated carbon rods (extrusion or sintering) are an indispensable and important unit in household water purification devices. Its main function is to remove residual chlorine and unpleasant taste in tap water (improving taste), and to remove organic pollution in water. Therefore, almost all household water purifiers are equipped with activated carbon sticks. However, carbon rods are a hotbed for bacteria to grow easily. Therefore, running tap water through carbon rods can remove residual chlorine and organic pollutants, but at the same time it may increase the number of bacterial colonies in the water. [0003] Chinese patent CN1314204 discloses a composite material carrier activated carbon rod and its preparation method. The carrier material ...
