Application of vacuum drying oven in the development of polymer film

With the enhancement of environmental awareness, the development and application of environmental science and technology have been greatly developed Polymer membrane is one of them It is mainly used for material separation and microporous filtration Thanks to its special structure, it can distribute water or gas on one side of the membrane and only allow certain small particles or organic substances to pass through Separation of biogas from CO2 and desalination of seawater are the application of this technology Polymer membrane technology is also used as an important component of fuel cell, not only for gas separation, but also for electrolyte separation and even proton conduction Many universities and research institutions are committed to the research of this technology, striving to make it more resistant to high temperature, better gas permeability and selectivity, and cheaper With the enhancement of environmental awareness, the development and application of environmental science and technology have been greatly developed Polymer membrane is one of them It is mainly used for material separation and microporous filtration Thanks to its special structure, it can distribute water or gas on one side of the membrane and only allow certain small particles or organic substances to pass through Separation of biogas from CO2 and desalination of seawater are the application of this technology Polymer membrane technology is also used as an important component of fuel cell, not only for gas separation, but also for electrolyte separation and even proton conduction Many universities and research institutions are committed to the research of this technology, striving to make it more resistant to high temperature, better gas permeability and selectivity, and cheaper Fuel cell in automobile is one of the application fields of polymer membrane One of the research topics is to use polysulfone and silicon particles as matrix mechanism of polymer membrane to form filter membrane Polysulfone is a kind of plastic with good high temperature resistance In this study, we need to detect the morphology and homogeneity of polymer membrane under different loading and different silicon content The vacuum drying oven of hasuc plays an important role in the production of polymer film On the one hand, before the polysulfone is combined with the membrane, it needs to be dried in a vacuum drying oven at 100 ° C; on the other hand, when the polymer membrane is dried at room temperature, the vacuum drying oven is used to remove gas and residual solvent from the polymer membrane The morphology and homogeneity of the film were observed by SEM when the content of silicon particles was 8% and 12%
