Huge profits: uncovering the new technology of 2 1 century-the scam of nano sputtering. At present, there is a so-called nano-sputtering technology on the market, which can achieve electroplating effect on anything. Is it really nano? Can you really use any products? Is there really no quality problem? You must want to know what nano sputtering is all about, right? Is it really as mysterious as the salesperson said? So good? Let me tell you what nano sputtering is. In fact, the so-called nano-sputtering is the silver mirror reaction in chemistry textbooks when reading. In this reaction, the silver ammonia solution generated by silver nitrate and ammonia water contains silver diammonium hydroxide, which is a weak oxidant. It can oxidize acetaldehyde to acetic acid, which reacts with ammonia to produce ammonia acetate, and silver ions are reduced to metallic silver. The silver produced by reduction adheres to the test tube wall to form a silver mirror. This reaction is called silver mirror reaction. Its formula is: 2% silver nitrate solution, 2% ammonia water, 5% sodium hydroxide, solution A (40% acetaldehyde: ethanol = 1: 1), solution B (40% acetic acid) and solution C (10% glucose solution). (The technical parameters have been tested by the technicians of a company and confirmed to be OK. Compared with the quotation of nano-spraying below, we actually understand what is the profit margin of nano-spraying and why it is called profiteering. The quotation of nano-spraying consumables is named as unit price (RMB). The minimum order quantity is K 1 dosage 36.00/L 20L/ barrel 60L/ barrel K2 60.00/L 20L/ barrel A 1 dosage 150.00/L 20L/ barrel A2 30.00/ barrel. The cost of agent B in the market is 42.00/L 20L*2/ barrel 120L/ barrel S 30.00/L 20L/ barrel 60L/ barrel of water per ton 1.00- 1.50 yuan. After purification, adding labor is 2.00 yuan, and one ton of water is equal to 10. Based on the cheapest A2 per liter of 30 yuan, the minimum order is 60 liters. The water content is 58.8 liters. In other words, 58.8 liters of water was purified and sold for 1764 yuan. If the highest price is A 1, the minimum order is 60 liters. The water content is also 58.8 liters. In other words, 58.8 liters of water was purified and sold for 8820 yuan. Not counting this, a nano sprayer, a stainless steel shell, a set of pure water processor and several spray guns will cost 10 to 200,000 RMB. Compared with the so-called nano-spraying, it only changes the reaction mode from soaking to painting. In order to mislead customers, sell it at a good price and change its name to nano-spray. What is the principle? This problem depends on how to understand the concepts of nano-sputtering and silver mirror reaction. One is to understand it as a technical term, that is, reducing silver ammonia solution with aldehydes or compounds containing aldehyde groups (under the existing conditions, the types of substances can be expanded) to deposit silver on the surface of products and form a silver mirror reaction, so when it comes to silver mirror reaction, it is natural to think of silver ammonia solution and its preparation method, some conditions of the reaction and some factors affecting the quality of silver mirror, as well as reducing sugar in aldehydes, aldehyde groups and reducing organic substances. When it comes to things that can react with silver mirrors, immediately analyze whether they contain aldehyde groups. How many times did you earn? However, the method of nano-spraying configuration is actually adding water. 2% silver nitrate solution In the silver mirror reaction, the ratio of silver nitrate solution is 2%: 2% silver nitrate solution is prepared with distilled water. Nano-spray can be changed into a 150 yuan and a 1 liter. Preparation of ammonia water in silver mirror reaction: 2% ammonia water was prepared with distilled water. Nano-spraying can be changed into A2 for 30 yuan 1 liter. Everyone will definitely ask: Why do you want to add so much water? Silver ammonia solution can also be prepared, because when preparing silver ammonia solution, it is necessary to prevent adding too much ammonia water. Otherwise, Ag3N may be produced, and there is a danger of explosion when heated or hit, and the silver ammonia solution itself will lose its sensitivity. If AgNO3 _ 3 is dropped into ammonia water, it will produce explosive substances due to excessive ammonia water. At present, someone has bought a nano sprayer. How many products did they make? I used it when I first bought it, but I gave up when I really found the problem. Why? First, the production cost is high. Because it is sprayed, it is a great waste. Just look at the quotation of consumables above. Is the production cost really high? It's not high to spend tens or hundreds of dollars 1 liter of water at every turn. Secondly, because the silver mirror reaction is not attached at all. At present, the manufacturers selling nano-spraying in the market are only allowed to adhere to the products for a short time after spraying, and then leave them for a few days, which is impossible for customers to accept. This is why three years later, the finished product of nano-spraying has not appeared on the market. Therefore, customers who have bought nano-spraying at present have given up using it.
