The types and functions of ultrafilter for cathodic electrodeposition(CED) painting and the functions of charged membrane ultrafilter for CED have been described.
In copper electrolytic refining,high quality cathode copper can be produced by adding WHN1 together with suitable amount of gelatin and sulfocarbamide.
Based on different soil corrosion factors and pipe corrosion principle, obligated current negode protection and sacrifice anode protection can be used here.
Several kinds of tungsten thermonic cathode were introduced.Moreover, the advances in the cathode with a monoatomic layer on the molybdenum substrate were reviewed.
This system has superior performance in image quality, space resolution , ?m and nm Cathodoluminescence image and spectrum analysis of semiconductor materials.
The structure of the MIGmust be carefully selected, as the tiny change on it will affect beam performance highly, and beam current will fluctuate punily.
The metabolism of hydrogen which involved hydrogenase was the main reason for the MIC of AZ91 alloy.The SRB accelerated the cathodic reaction through the cathodic depolarization.
The working characteristics of heated negative pole power source of intervallic heat electricgun are introduced in this paper.The method of heated power's indirect test is advanced.
To realize the high efficiency of dernisting, thenew type cathode wires and anode tubes with superperformance were developed for increasing the current density and field intensity.
Streak cathod method which is a kind of qualitative method for measuring the innerstress of deposits was introduced.A semi-quantitative calculating formula for the innerstress was given.
Brazing quality and product reliability are both increased as using high frequency pulse microplasma arc heating process for assembly brazing of cathode and photoetching grid of electron tube.
Has the cathoderay tube (teletron) the equipment, in one starting time, the developing surface will attract the plastic, the grass, the dust, the thin metal and so on any material.
A divided flow cell is used for electrolysis of NaBr aqueous solution.The anolyte containing Br 2 and catholyte containing NaOH are produced simultaneously and in turn to epoxide HFP to HFPO.
