First (or running water) pours into 1/2 deionized water in the trough, then joins 3-5 kilogram rubber peptide table to fill a prescription, after when agitation note full remainder water b) PH value somewhat low, compounds 10% water-soluble fluid adjustment after the sodium hydroxide or supplements aBD c) to pass through long time processing, the tank liquor easy to get older, the table adjusts the effect to drop, this time should replace the tank liquor MMMY is one kind of white solid powder, may reduce the phosphorization time, the activation work piece surface, the acceleration phosphorization membrane becomes the membrane speed, and reduces the phosphorization temperature.May enhance the phosphorization membrane the quality, eliminates the alkalinity to eliminate the oil or the acidity eliminates the rust to cause the corrosion not equal flaw.Increase nucleus quantity, causes the phosphorization membrane crystal to be compact, enhances bears the counterfeit.Can reduce the phosphorization cost, the extension phosphorization fluid life Takes the 10ml driving fluid in the conical flask, joins 3~4 drop of phenol tai indicator, swings uniform, with 0.1NNaOH standard titrate, when the solution becomes red is the end point of titration, consumes a standard fluid milliliter number installs the driving fluid for the total acidity points with the fermentation tube (tube crown not to be able to have air bubble), joins spoon thionamic acid, the rapid inversion, after waits the response to finish, reads has the gas number of division, namely for promoter points Each ton supplements MYCDEE to make the total acidity to enhance, if the free acid excessively is high, then adjusts with the neutralizaing agent.The promoter adopts little adds, the industrious Canada's way, avoids disposable joining the quantity oversized or the local concentration excessively is high
我是化学高手,但对于这个,我无能为力
