Sorry, and good luck. Currently, I'm into restoration of old motorcycles, especially Antique Harley Davidsons. All refer to using it but where do you get it? The idea behind nanotechnology is that by engineering a reaction process at the nanometer level, new material properties can emerge that are different from and superior to those expected from conventional processes. They also call it Manganese phosphating. Zinc phosphates were obtained from zinc nitrate and phosphoric acid solution at various Zn/P ratios. I did not see any active reactions in phosphoric acid when I added MnO2 to it initially. Source(s): https://shrinkurl.im/a7WdO. "palette": { Ted Mooney, P.E. Thanks for teaching. Rich. affil. How often are you check the conditions? Each of the three types provides a phosphate coating with slightly different properties, such as crystal size and coating thickness. A. A. You can either purchase premixed nutrients, or you can mix your own. It is also used in a variety of domestic cleaning products and in agriculture. "Phosphating of Metals" }); Preclean was perfect, no signs were found like oil and others. CALCULATIONS If NaCl were the only solute, the amount needed would be We often used this technique when finishing .45s built on early Essex frames that needed a lot of fitting, thus often requiring the removal of offending metal. link by editor] have one in the USA but it is not available in Australia, and they won't send it due to probs sending Chems by post or Courier.. A. "popup": { 2005 but continuing through 2019. A. Hello Deep. 1. After some reading I decided to go with a nitrate accelerated bath with the following concentrations: I understand nanotechnology to mean engineering of the coating at the nanoscale level, taking advantage of phenomena that emerge at the nano level. 10X is a concentrated or stock solution, which may be diluted to make a 1X or normal solution. Use one whiskey jigger (yeah, this is really scientific, right?) Delaphos has been a leading brand of Zinc Phosphate for over 40 years and … A. Dear Amitabh "background": "#fff", A.

Cosmoline, it would give the sometimes sought after "gray-green" tint to it. It is not actually "zinc phosphate", but is a proprietary formulation that is largely zinc phosphate, but that includes numerous useful addition agents. No active out-gassing at the surface occurred, a dark grey, but lighter shade of grey deposit formed. 2. I don't think you should switch to anything unproven, but only to a process where you can see samples that have been exposed for a dozen years or so. DON'T use painted coat hangers or any wire with grease on it! Firstly, I wondered how can I make zinc phosphate solution and how can I use bath tips? - They look very close to some of the other formulas I've seen for parkerizing. The speckles from stainless steel is chromium or nickel dissolved in the acid that makes up a main part of the SS alloy. A. Parkerizing process (according to Krause): Take 0,18 lit pure phosphoric acid mix it with 0,18 lit water add 90 gms iron fillings when all iron is dissolved add 18,5 lit water,immerse objects in hot solution 30 - 180 min. Zinc nitrate 0.5-1.5% 1.50 kg An alkaline detergent is used to clean the surface to ensure the zinc electroplating is of good quality, and the plating remains intact for a long period of time. Q. - If it's precipitated out I'd think that it's not doing much for the chemistry of the bath, filter it out and set aside. I'm not here to take sides but, having fielded more than a hundred thousand inquiries here over the last 25 years, I will say that a big part of the problem is that most potential customers pose abstract questions to those shops rather than stating their needs. Chinese patent CN1259451C has been useful and sounds like good results are possible at room temp, but the total bill of materials would be very expensive for a home workshop, considering the volume needed (approximately 140l), so I would like some feedback regarding which of the chemicals are necessary, and which could be done without in exchange for longer treatment time, for example. Consult'g, Train'g, Software Environmental Compliance. Once the solution gets to about 180°F, drop the degreased pad of steel wool into the parkerizing solution and allow it to begin dissolving.

Dissolve zinc in acid.Take 6,5 parts of this solution and mix it with A. I assume you are but I thought I would ask. Realistically, you'll have to depend on your supplier to resolve this problem or to change suppliers, as we unfortunately have no idea what the chemistry even is that is falling apart on you when heated. A 5X solution must be diluted 5 times to make a normal dilution, while a 10X solution must be diluted 10 times. Good luck. Powdered Manganese Dioxide (a very dense and heavy dark gray to black powder) also available at any chemical supply house. Do you have a formula for Manganese Phosphate solution ? There is a lot of good information out there but I am keen to find a solution that works at room temperature due to the difficulties heating a bike-sized tank to the boiling temperatures normally used.
