Problems solved by technology

In the laboratory, if the amount of coating liquid prepared is small, the hollow fiber membrane is generally placed directly in the beaker for coating, but it is easy to make the membranes stick to each other and the membrane sticks to the cup wall, resulting in the coating effect. Poor and Hollow Fiber Membrane Bending

specific Embodiment approach

[0010] The fixed film part is composed of two circular iron wires (1) (2) parallel to each other up and down, such as figure 1 shown. Take a pliable iron wire and twist one end of the wire with hand pliers to form a first circle, the diameter of which is slightly smaller than the diameter of the coating cylinder. According to the amount of coating liquid prepared, at a certain distance from the first circle, twist the iron wire into a second circle with pliers, and the size of the second circle is equal to and parallel to the first circle. The part of the wire (3) that connects the two circles is used as the support part, and the remaining part of the wire (4) is used as the handle part.

[0011] The present invention is suitable for manual application, such as figure 2 shown. The upper and lower two round iron wires are used to fix the hollow fiber membrane (5), and the tool of the present invention is directly placed in the measuring cylinder (6) containing the coating l...

Abstract

The invention provides a simple hollow fiber membrane coating tool, which comprises a hollow fiber membrane fixing part, a support part, and a handle. The hollow fiber membrane fixing part fixes a hollow fiber membrane; a user can hold the handle to soak the tool in a graduated cylinder filled with coating liquid; the support part is tightly pressed against the inner wall of the graduated cylinder; and the hollow fiber membrane is evenly painted.

Description

technical field [0001] The invention relates to a coating tool for coating hollow fiber membranes. Background technique [0002] Hollow fiber membranes often require superhydrophobic modification to improve wetting resistance for application in membrane distillation processes. The simplest superhydrophobic modification method for hollow fiber membranes is the dip coating method. In the laboratory, if the amount of coating liquid prepared is small, the hollow fiber membrane is generally placed directly in the beaker for coating, but it is easy to make the membranes stick to each other and the membrane sticks to the cup wall, resulting in the coating effect. Poor and hollow fiber membrane bending. In order to ensure the anti-wetting effect of the film, the most important coating requirement is the uniformity of coating. Contents of the invention [0003] The problem to be solved by the present invention is to provide a simple tool for coating hollow fiber membranes in the...
