The first patent for the use of electrophoretic painting was awarded in 1917 to Davey and General Electric. Since the 1920s, the process has been used for the deposition of rubber latex. In the 1930s the first patents were issued which described base neutralized, water dispersible resins specifically designed for EPD.
Most coatings have four basic components. These are the resin, solvent, pigment and additive systems [5] but the resin or binder is the key ingredient. Continuing environmental legislation in many countries along with geopolitics such as oil production are ensuring that chemists are increasingly turning to waterborne technology for paint/coatings and since resins or binders are the most ...
Electrophoretic deposition, a term for a broad range of industrial processes which includes electrocoating, e-coating, cathodic electrodeposition, anodic electrodeposition and electrophoretic coating, or electrophoretic painting
1. Illustration of electrophoresis. 2. Illustration of electrophoresis retardation. Electrophoresis is the motion of charged dispersed particles or dissolved charged molecules relative to a fluid under the influence of a spatially uniform electric field.
In these equations r H presents the hydrodynamic radius of the colloids, – the speed of electrophoretic migration, – the dynamic viscosity of the solutions, – dielectric constant in vacuum, is water’s relative dielectric constant at 298 K, is the zeta potential, E is the electric field. The hydrodynamic radius is the sum of particles ...
The Bahamas has “firmly rejected” President-election Donald Trump's proposal to fly deported immigrants out of the U.S. and into the small island nation about 100 miles southeast of Florida ...
Many different types of nanomaterials or nanoparticles are used in water treatment processes. Nanotechnology is useful in regards to remediation, desalination, filtration, purification and water treatment. The main features that make nanoparticles effective for water treatment are More surface area; Small volume
