Contrast solid circle WoRLDNoNFERRoUETALS Research and Application of population by 42% if the base ion-exchange membrane, if the alkali 250t dollars per day, tons of liquid alkali into C BU reduced by 18.66kg 0.139kg. I plant started from November 2000, Bayer has been using caustic alkali make alkali, after running a half months of a Cl content of the system to do a test, the results shown in Table 5. Table 5 after I plant using ion-exchange membrane alkaline solution with the use of diaphragm caustic soda when comparing samples of Cl content in the name of a Cl a content (g / 1) 2002 年 1O months (when the use of diaphragm caustic soda) December 2002 (after the use of ion-exchange membrane alkaline) which may account for that, such as the use of 42% instead of 30% caustic alkali membrane base, is able to greatly reduce the accumulation of cl in the process, which is already in production has been confirmed. 6, Conclusion (1) the production process of alumina content of the material in the C accumulated to a certain degree of divination,moncler outlet, not only the corrosion of equipment and a greater direct impact on process indicators, but indicators of the degree of influence on the process that we know little about this theory and field practical point of view, summarized its analysis, and it highlighted the impact of evaporation and decomposition process. Although C can increase the dissolution rate of divination, but in improving the AI (OH), but also reduces the equilibrium concentration of solution c'k, increases the solution viscosity, resulting in decreased decomposition rate seed,ugg prezzo, thinner size, product decline in the quality, evaporation system operation difficulties, which greatly affected the efficiency of evaporation and the evaporation of mother liquor caustic stability. (2) removal of chloride ions through the three methods are broadly comparable, in the process of alumina membrane base on OK to replace the diaphragm base, one out of the new balance of Cl is established, will be gradually restored to the optimum needed for the production equilibrium.

There is no market for those products, operational difficulties, insolvent liquidation of economic entities should be based on the spirit of \4 Strengthening monitoring of economic entities, corporate debt liabilities of the economic entities is a high note, and these economic entities borrowing from banks, most of them sponsored enterprises with credit, credit guarantee provided by the host companies. According to the survey, some economic entities assets and liabilities was 100%, the highest of as high as 139%. If a large number of companies offering dozens of economic entities, according to incomplete statistics, only one of four economic entities to provide tens of millions of credit guarantees, to the current 63.59 million yuan is not only not to return, and some running problems Some have been closed, no hope of repayment, facing litigation. Although there are many reasons for this dilemma, but mainly the first few years of economic overheating, the host business and the economic entities of 30 did not adhere to the \management capacity, lack of consideration of possible consequences and judgments,stivali ugg, blind expansion, anxious, hot-headed, reckless investments caused. To deal with these historical issues, not a small price to pay and costs. We must remember the lessons of history and prevent similar cases from happening again. Although debt management is a business strategy, but with high risk, sponsored enterprises must enhance the economic entities of regulatory liabilities, so that the economic entities to maintain a proper balance can bear. Meanwhile,air jordans, profits must be established for the purpose of strict scientific investment decision-making system, adhere to project feasibility studies, adhere to the capabilities, and adhere to the scientific management, to consider borrowing channels, staggered loan period to avoid over-concentration of repayment. Meanwhile, investment decisions should fail to establish accountability system, for playing almost his duty, reckless decision-making led to investment failure, causing heavy losses to the state responsibility should be held accountable. The economic entities of the business be sorted out involves many sectors, not only the need of government attention, but also government and corporate authorities of a unified organization and leadership. Specific work might be necessary should the typical survey, find out the situation, based on policy, target, an organized scheme. 相关的主题文章： ugg prezzo Meshing purposes, manufacturing and trends _1599 ed hardy Development of CNC machine tools world _2274 ugg stivali Anodized aluminum microstructure and p |
