1.Q: What is electrophoresis?
A: Electrophoresis is the motion of dispersed particles relative to a fluid under the influence of a spatially uniform electric field. The technique applies a negative charge so proteins move towards a positive charge. It is ultimately caused by the presence of a charged interface between the particle surface and the surrounding fluid.
2. Q: What is zinc phosphating in surface treatment?
A:Zinc phosphating is used to coat ferrous metals to provide rust-proofing and, when applied in conjunction with sealers, superior corrosion protection. Zinc phosphate is a lighter coating than manganese phosphate and is used as an alternative coating for high wear parts. Phosphate coatings are porous, making them ideal for surface preparation for additional coatings and painting. The zinc phosphate coating protects the underlying part surface from wear, corrosion, and rust.
