Enova has developed a new tin dissolution process based on insoluble anode technology. Based on the oxidation of tin particles, the tin electrolyte is allowed to flow in the solution reactor, and the electrolyte becomes a saturated oxygen-containing liquid, thereby accelerating the oxidation reaction, causing the metal tin to become tin ions, and finally realizing the tin plating of the strip. The application of insoluble anode technology minimizes the amount of residue generated in tin plating production, thus minimizing the loss of precious metal tin, while improving the quality of tin plated steel, achieving better control of the process and eliminating the working environment. Phenol vapor. 1 insoluble anode process advantages The advantage of the soluble anode is that the anode can automatically generate a cathode aggregation effect on the strip surface by anodic tin dissolution, however, it has many disadvantages. The fatal disadvantage is that all electrolytes must be exhausted due to the different electrochemical efficiencies in the electroplating and dissolution process. Secondly, the use of tin anodes inevitably has to be diluted due to the increase in the concentration of tin in the electrolyte, resulting in overflow. And the loss of tin and water pollution. In addition, the soluble anode tin plating process has low productivity, flue gas is present in the plating bath, and the anode needs to be processed during production. At the same time, the soluble anode process also has defects such as the uniformity of the plating layer decreasing with the decrease of the thickness of the plating layer, and thus it is difficult to produce a high-quality tin plate with a plating thickness as low as 0.2 to 0.4 g/m2 which is rapidly required in the market. Insoluble anode tin plating was developed to solve the fatal defect of the soluble anode, so it has the following advantages: Low tin consumption (due to uniform coverage of tin on the strip surface); 2The quality of tin plating is high (even if the tin plating amount is less than 1g/m2, the surface and edge of the strip can be uniformly coated with tin); 3 low cost, high productivity, production flexibility and safety; 4 less smoke, good working environment (plating tank stamping); 5 no need for anode melting workshop; 6 electrolyte consumption is low; 7 low power consumption. 2 technology development The new tin dissolution process has been proven by the long-term continuous operation of the electrolytic tin plating line of TerniumSiderar. Its advantages are as described above: low power consumption, low tin consumption, high output, high quality, safety and environmental protection. Practice has confirmed that the optimal design of the anode and strip edge shielding allows the dissolution shop to be highly efficient and productive. Since the inertness of titanium and the adhesion of the surface oxide film are extremely strong and can resist the acid corrosion of the electrolyte well, the anode optimization can be accomplished with a titanium-based anode. The insoluble anode is placed perpendicular to the horizontal direction in an electrolytic cell containing the electrolyte, and a distance of less than 50 mm is maintained between the moving strip and the electrolyte is blown into the gap between the strip and the anode. Due to the very high speed of the strip movement, the electrolyzer will promote the contact between the strip and the anode due to the hydrodynamic effect of forming a "venturi" between the strip and the anode, resulting in strip defects. To this end, an anode design with a regular arrangement has been completed. When the horizontal gap of the upper and lower movements of the electrolytic cell is reduced, the distribution design of the holes is completed to maintain the current density continuously distributed in the lateral direction, thereby reducing and eliminating the strip defects caused by the venturi effect. 3 insoluble anode operation effect There was no tin plating tinning defect associated with the use of the anode during production, which proved that the optimum design and material selection of the anode fully met the process requirements. Since the width of the insoluble anode is fixed, in order to accommodate tinning of different width strips, an electrically insulating sheet, that is, an edge shield, is commonly used to prevent "white edge" defects. To plate the strip with a tin film, it must be placed in a "U" section and placed on the end face of the shield. The quality and quantity of tin plating on the edge of the strip depends on whether the depth of its insertion into the U-shaped section is scientific. Therefore, it is necessary to ensure and realize that the U-shaped segment moves accurately with the movement of the strip, and it is desirable that the degree of unsynchronization is less than 1 mm. On the TerniumSiderar line, an edge shield system with two pairs of FRP edge shields is mounted on the cell. An inductive sensor for strip permeability inspection (driven by a servo cylinder with a linear converter) is installed in each pair of FRP shields. The design of the edge shield ensures easy inspection and maintenance of the cell and ensures flexibility in its operation. The local shield communicates with the PLC of the job, and the edge shield controls and tracks the position of the weld head and allows the strip width information to be sent to the local PLC. The reliability of the system is improved by equipping the edge shielding system with two edge sensors. When any one sensor fails, the other sensor also ensures the normal operation of the system. The development of electrolyte supply standards in accordance with the needs of tin plating lines, important operations, and maintenance of actual needs has been completed. The proof of use is very good and the tin loss in the residue is quite low. 4 use prospects It has been proven that insoluble anode technology can be used to build new plants as well as upgrade existing plants. Recently, Tenova has supplied a new set of insoluble anode tinning lines and a set of tin dissolving equipment for Chinese steel mills with an annual output of more than 250,000 tons, a process speed of up to 550 m/min and equipped with an edge shield system. It was opened in 2009. According to the production capacity and technical level of the production line and equipment performance, it will be the most important insoluble anode tinning production plant in the world. It is responsible for accumulating experience and completing the technical development of high-speed production lines, providing more for the two factories of ArcelorMital and Erdemir in Turkey.

WHAT MAKE UP AN EXCELLENT LED GROW LIGHT ?
1.PPFD Value : PPFD is Photosynthetic Photon Flux Density. When you choose a plant light, you should compare the PPFD values of different plant lights. The larger the value, the better the growth of the plant.
2.Actual Power: Because the actual power of the plant light always varies with different conditions, all Amazon sellers use the rated power to describe the power of the product because the rated power is constant. When you pick a LED grow light, the rated power of the plant light is a reference, and more importantly is the actual power.
3.Core Coverage: In addition to the above two, when you choose a plant light, you also need to compare the cover area of different plant lights, of course, the size of the core coverage area. In general, in germination stage, you can hang the plant light higher and the cover area is larger. In flowering stage you can hang the plant light lower and the cover area is smaller because the plant needs more light at this stage. You have to compare different coverage areas to choose the plant light that suits you.
