nafion nr 50 (beads 10-35 mesh) - Introduction
nafion nr 50 (beads 10-35 mesh) is a special ion exchange membrane, invented and popularized by DuPont in the 1960 s. It has many unique properties.
First of all, nafion nr 50 (beams 10-35 mesh) has very high proton conduction properties. This makes it ideal for proton exchange membranes in fuel cells. It can effectively separate water and transport protons, thereby promoting the normal operation of the fuel cell. In addition, nafion nr 50 (beads 10-35 mesh) also has excellent chemical stability and can withstand corrosion in acidic and alkaline environments.
nafion nr 50 (beads 10-35 mesh) is widely used in the field of fuel cells. It can be used in polymer electrolyte membrane fuel cells (PEMFC) and direct methanol fuel cells (DMFC). In addition, it can also be used in other fields such as water electrolysis and electrochemical synthesis.
There are several methods for manufacturing nafion nr 50 (beads 10-35 mesh). The most common method is by polymer synthesis. First, a tetrafluoroethylene-containing template is prepared by a high-temperature volatilization method or a gel method. Then, it is reacted with a monomer such as vinyl fluoride iodide in the template, and polymerized to form a Nafion material. Finally, by acid or solvent treatment, nafion nr 50 (beads 10-35 mesh) with a specific shape and size is obtained.
Regarding the safety information of nafion nr 50 (beats 10-35 mesh), it is a relatively safe material. However, under heat, pressure or high temperature conditions, nafion nr 50 (beads 10-35 mesh) may release harmful gases such as fluorine gas. Therefore, the operation and use of nafion nr 50 (beads 10-35 mesh) should follow the appropriate safety procedures to ensure effective ventilation and the use of protective equipment. In addition, Nafion materials also have a certain degree of water absorption, so care should be taken to avoid excessive humidity during storage and transportation.
