The surface quality of cathode copper is a system matter and has many influent factors, such as anode plate quality, starting sheet quality, bath composition, additive kinds and fashions, temperature of electrolysis, electrolyte circulation, electrolyte purification, anode slime, cathode cleaning quality, the last products storage and so on.
The Cleaning Machine of Nickel Anode Plate is an automatic machine device that is applied especially in cleaning the mud on the Nickel Anode Plate. In the process of electrolyze nickel, a great deal of anode mud adhere the nickel anode plate, which severe influence production efficiency of the electrolyzing nickel, but manual cleaning efficiency is so low that had fall back on the automatic machine device.
A high temperature oxygen sensor was used to track the change of oxygen and to direct the refining operation during the test of refining anodic copper. The result of experiment, a smooth surface and high physical quality anodic plate was successfully got from raw copper containing high nickel and sulphur.
2) intelligent vague control technical advantage develop fully the comprehensive optimization that need to combine the condition of engineering technology , is taking this as prerequisite and have established with current intelligent vague control technical aluminum electrolysis groove the adaptive condition of engineering technology of appearance,: Low member than , low electrolysis temperature, low alumina density, the low effect coefficient of positive pole and high voltage ( high polar distance).
Major research content and accomplishment are:1) the prerequisite that changes Qinghai branch electrolysis groove basically structural, bus disposition and the span of positive pole adopts the structure of positive pole , and it is of 1500 mm to go to the size of positive pole from the extension of 1400 mm, the industrial test result and purpose that can reach reinforced current show that the electrolysis groove after reinforcement is completely feasible on teclinology and technology.
It is necessary to select the catalyst with proper Pt loading when the anode of a direct-methanol fuel cell is prepared.
In this panel, field emission electrons are extracted directly from the cathode by the high anode voltage.
Instead of the traditional screen-printing method, both anode and cathode catalysts were pressed simultaneously and formed with the fabrication of nano-composite electrolyte by press method.
Maximum power densities 40 mW·cm-2 and 130 mW·cm-2 for the PEN configuration with a Mo-Ni-S-based composite anode, nano-composite electrolyte (Li2SO4+Al2O3) film and a NiO-based composite cathode were achieved at 600°C and 680°C, respectively.
Anode peak voltages (Eap) and their pH dependences were determined for the studied phenolic acids and flavonoids.
A set of 12-parameter rectangular plate element with high accuracy
Using the method of undetermined function, a set of 12 parameter rectangular plate element with double set parameter and geometry symmetry is constructed.
Their consistency error are O(h2), one order higher than the usual 12 parameter rectangular plate elements.
A fourth-order variational inequality of the second kind arising in a plate frictional bending problem is considered.
Recent developments of the ultra-wideband (UWB) planar antennas are reviewed, where the progress in UWB plate monopole antennas, UWB printed monopole antennas and the UWB printed slot antennas is introduced and compared.
Positive sign of this value proves the fact that the water dipoles are oriented by the negative pole toward the gaseous phase, whereas by the positive pole, toward the liquid phase.
Negative sign of surface potential for the studied organic liquids confirms that their dipoles are oriented by the positive pole toward the gaseous phase, whereas by their negative pole, toward the liquid phase.
The C4 bandof Rattus norvegicus caraco andLepus timidus located between the bands of LDH4 and LDHS and the C4 band ofErinaceus europaeus, a primitical animal, located to the farther side of LDHS and moving very slow to the positive pole.
The patient's serum amylase isozyme pattern by electrophoresis showed a broad abnormal peak toward the side of the positive pole compared with regular salivary and pancreatic fractions.
Factor I comprises the symptoms, disorder of orientation and consciousness, sweating, agitation and tremor on its positive pole, the duration of the delirant state on its negative pole.
