  Bar corrosion protection coating results. Then consolidate the situation, and ultimately determine the anti-corrosion coating for the metal layer and high-performance composite coating layer. Specific process requirements and film thickness in Table 1. Table 1, anti-corrosion layer thickness of 2 technical requirements and implementation of 2.1 anti-corrosion coating technology from the open forest to provide coatings paint factory, due to the eleven test surface coating design is white, and Engineering Command requires open forest plant supply aluminum acid color, so on the ball and aluminum curtain wall with the same color. Therefore,ugg udsalg, the open-forest plant and across the coating to a large number of comparison tests, combined with the construction of the practical problems, including damage at the meeting painted, painted,ugg australia, etc. after the completion of the pass, the command has agreed to eleven in the face of the program established coatings has been modified in Table 2.

  Silver Strip Corrosion jet fuel rapid determination method of
  
  
  Electronic gains and losses of the chemical reaction to form a primary cell or electrolytic cell often can greatly accelerate the speed of chemical reactions. So consider the introduction of electrochemical corrosion in the silver pieces to speed up the silver corrosion test piece corrosion reaction at 0V, 9V, 15V,ugg zürich, 30V voltage power supply 224 under study plus the corrosion rate of the silver film,uggs nederland, the results in Table 2 (experimental devices such as Figure 1. To improve the conductivity of jet fuel. with 30 solvents) Table 2 Experimental results show. Silver film applied voltage after the initial emergence of corrosion and corrosion level reached was significantly shorter time,ugg suisse,ugg saappaat suomesta, and the higher the voltage,ugg bruxelles,ugg boots schweiz, the shorter the time required, that additional power can effectively improve the corrosion rate of silver pieces. May be due to its original solid: ① the electric field increases in jet fuel sulfur molecules active energy,ugg geneve, which is higher than the activation energy increase in the number of molecules; ② electric field near the silver film increases the local concentration of reactants. Thereby speeding up the corrosion reaction rate. 3.3 polar solvents and corrosion rate of the silver film as jet fuel is a relationship between the non-polar liquids, electrical conductivity is poor. Therefore,ugg boots schweiz, adding polar solvent to make a smooth electrochemical reaction occurs in the oil sample in a certain amount of ethanol after the experiment to measure the device shown in Figure 1 in the current intensity, found that the current was significantly increased (from the 0.32 ~ o. 35p-A to 1.78 ~ 1.98 ~ A). Silver Strip Corrosion Test at the same time significantly reducing the time, the experimental results shown in Table 3. Shows that adding polar solvents to improve the conductivity of the oil sample. The electrochemical

  Heat, humidity,uggs skor, liquid chlorine ions are concentrated, some chlorine gas with water Shuimo is half saturated with the tower. (2) chloride ions flow into the heat exchanger means of the saturation tower ~ 1200mm swirl plate tower, the last two years, as production capacity has been greatly improved, resulting in the saturation tower airspeed is almost close to the Pan- point of gas velocity, resulting in half-saturated water tower outlet gas may continuously with water regularly. Also due to catch the foam, steam separator,uggs australia, steam mixer were not equipped, so that semi-water gas will be easily entrained chloride directly into the heat exchanger Shuimo. (3) corrosion of parts of the analysis of why the corrosion occurred in the next most serious parts of the flower and the upper plate of the tube sections only 500mm it? When a certain amount of chloride ion Shuimo together with the semi-water gas into the heat exchanger under the head, the part of Shuimo immediately hit the bottom plate under the flowers, the rest of the Shuimo continue into the air tube, and the collision wall - due to air in a turbulent, Shuimo easily wall collisions; and almost immediately entered the tube hit on hit the wall. Then, hit across the board and under take the bottom wall of the tube is heated Shuimo immediately, the water is evaporated, chloride ions are concentrated, along with the transient heat and mass transfer process, while at high temperatures (wall temperature above 200 ℃) under the action of high concentrations of chloride and stainless steel metal atoms in the severe chemical reaction to produce metal chlorides, the steel degeneration. This is the next flower plate heat exchanger tube and its upper corrosion by chloride ions causes. Stripping parts from corrosion of the sample analysis results, the powder in the tube wall chlorine> 8.29,6, not only confirmed the presence of chlorine system, and the solubility is very high. 5 Conclusion From the above analysis, the heat exchanger corrosion methods from the following aspects: (1) stainless steel heat exchanger core (up and down the flower plate, tube) material models,uggs online bestellen, you should select the molybdenum (Mo) series Stainless steel or low alloy steel, to enhance performance of chlorine-resistant material.
