Description of the invention (). The concentration of aluminum cations dissolved in a large amount of the composition on the adjacent surface of the conversion coating cannot be generated in large quantities, so the conversion coating process will produce Difficult, according to the present invention, it is possible to smoothly and perfectly provide a fluoride containing a "reservoir" in the component (B) of the implementation composition. The fluorine-containing complex anion has a dissociation equilibrium constant higher than that of zirconium hexafluoride salts. However, no excessive free fluoride is generated. For this purpose, tetrafluoroboric acid and its salts are considered to be a better choice, and it is better to use acids in consideration of cost; regardless of the source, the composition according to the implementation of the present invention In terms of measurement, the concentration of the dissolved tetrafluoroborate and the concentration of tetrafluoroborate are preferably equal to .005, 0.010, 0.020, 0.030, 0.040, 0. 045, 0. 047, 0. 049, or 0. 051 parts by weight / thousand parts in total to increase their priority selectivity; this concentration unit is often abbreviated as "PPt" at the bottom, and its selection is increased in order.

In addition to providing a "reservoir" fluoride which is as free as the original free state fluoride in composition 4, tetrafluoroborate is considered to have antiseptic effect because it contains boron; according to the present invention, it can be beneficial to the storage stability of the article. Because some storage items contain organic ingredients that help promote the entry of microorganisms in the surrounding environment; tetrafluoroborate has unknown factors to prevent contamination, and tetrafluoroborate is a stronger dissociating acid than HF, which helps control pH.

However, the composition according to the present invention is not greater than 1.0, 0.5, 03, 010, 0 050, 0 020, 0.00100, 0.050, 0.0020, 0.0010, 0 00095, 0090.90, 0.0085, or 0.00081 of any dissolved hydroxyphosphoric acid The percentage of the category includes ---; __________ 21 This paper standard stab towel 0 National Standard (CNS) A4 specification U10 X 297 Public love '538135

Employees of the Intellectual Property Bureau of the Ministry of Economic Affairs have printed the atomic weight of phosphorus, and the percentage value is sequentially increased. Some or all of the neutralized acids are found in the composition. : Phosphorus concentration, usually beer cans pass through the composition:: After the mouth is steamed, it will appear vague white; it will be advantageous to have inorganic cations exposed to the road afterwards, at least large: 'Low concentration of phosphorus containing 4 The self-enhanced φ human metal ions, Lai_zi and acidic ions used by Wang Xidali; in these experiments, the atomic concentration of the dish dissolved with anions or hydroxy acids according to the present invention is at least 0, 00010, 0 00020, 0.00000, 0.0000, 0.0000 ^ 50, 0.00060, 0.00070, 0.0000075, or 0.000008%, sequentially increasing the preference of their percentage values; that is, the concentrated composition of the present invention In the physical packaging, the concentration of each of the above components is higher than that of the implementation composition. The concentration packaging of each of the (A) to (ii) components that have been stated respectively is compared with the special concentration of the same composition of the implementation composition, which is at least 10 30, 50, 70, 90, 100, 150, 200, 300, 400, or 500 times the better concentration; higher-concentration concentrated packaging is more cost-effective, because the water added during use can reduce the ship The cost of transportation, but the reduction of concentration will reduce the suspension and phase separation during storage. If the whole is completely mixed before use, although this phase separation will not hurt, but it is prepared from concentrate When the composition of the present invention is implemented, the phase separation will increase the risk obtained by the concentration tear method. The pH value and the value of free fluoride are not linearly proportional to the concentration of ingredients such as the concentration of the file and the polymer, so the concentration of the concentrate is more specific. The value is related to the preferred pH value after dilution and the value of free fluoride to provide a better concentration of amidine and polymer;
