Original Factory Micro filtration membrane (M) series to Nigeria Importers
Original Factory Micro filtration membrane (M) series to Nigeria Importers Detail:
M series membrane can be divided into mixed cellulose, nylon-6, nylon-66, PES, PVDF, PTFE, PP type according to material.
Mixed cellulose micro membrane
A polymer film filter, mixed by nitrocelluolose and cellulose acetate. Pore extreme development, Effective porosity of up to 80%. Uniform aperture, small resistance, high flow speed, little absorption, no media loss during filtration.
Nylon-6, Nylon-66 microfiltration membrane
Representative aliphatic polyamide filter, with natural hydrophilic, positive charge. Pore development, pore forming with mesh, has excellent resistance to organic solvents, acid, alkali, heat. Meantime with high mechanical strength.
PES Microporous membrane
Sulfonated treatment to polymer polyethersulfone resin, bring in sulfonic acid gene. This membrane has good chemical compatibility, protein absorption rate lower than nylon. With high filtration precision, it is a safe sterile cartridge. Effective operture openins, high flux. Typical asymmetric pore structure, strong fouling resistance.
PVDF Microporous membrane
Fluorine type filter material. With natural hydrophobic, protein absorption rate is very low, excellent heat and chemical resistance, tolerated acid, aliphatic, aromatic vinyl alcohol, aldehydes, ketones and other organic and inorganic solvents. Can be used for both steam and liquid sterile filtration. High porosity, asymmetric pore structure, high pollutant capacity. Can be changed to hydrophilic membrane, used for solid and sterile filtration of high surface tension water based liquid.
PTFE Microporous membrane
Fluorine type filter material, with natural strong hydrophobic. Excellent heat resistance and widely chemical compatibility, bidirectional stretched into hole. Extremely development pore, It is an excellent steam sterile filter, also suitable for high corrosion, strong oxidizing organic solvent and inorganic solvent. With low gas resistance, high flux, it can be changed into hydrophilic membrane, used for solid and sterile filtration of high surface tension water base liquid.

Here I demonstrate how to make a very good capacitor using safe and easily available products.
How the graphene was made
How the capacitor was made……..
The plates…..You can use Aluminium as the plates or you could improve this by using activated carbon instead.
The Graphene……. You could make better quality graphene using alternative methods of production. You could apply a greater quantity of graphene resulting in better duration.
The electrolyte…….You could use an acid or an alkaline liquid of various types. Hint… Try potassium aluminum sulfate.
The dielectric… When it comes to Titanium Dioxide as dielectric, the thinner the film the better. This type of titanium is rutile so is no good for solar panel.
The reason I thinned the coating is because the DFT (Dry film thickness) will be less resulting in better current holding abilities. Generally speaking, a DFT of 10 to 15 microns produces the best results. The WFT (wet film thickness) is 70 to 75 microns.
The carrier… I used an acrylic latex (water based) because the micelle formation creates a continuous phase formation of the cured coating. This tends to aid the incorporated titanium dioxide with the graphene surface layer producing a robust, consistent and balanced system. It also enables the user to build the capacitor easily. And just by coincidence it performed better than PVA.
Thinner and more elastic films can be created and handled using an acrylic latex compared to most coatings of the same DFT.
The titanium dioxide provides the current(And current holding) for the system. The graphene provides the conduit for the power , and to a less extent the current holding ability, of the system.
I have not tried anatise titanium dioxide. although it would be interesting considering the make up of a solar cell. In theory a diy solar cell could be produced using the same system plus one other element…….. Maybe later
I hope you enjoedy this video and are inspired to create for yourself.
Thanks for watching.
