       Associate Professor of Shenyang University of Technology, Jiangsu Province, the ninth batch of science and technology town long group (Kunshan) members Zhou Qi

Zhou Qi: Leaders are good, my results are our school teachers developed their own, not and business cooperation, the results belong to the kind of business results, that is, I said these results can be transformed, that is, to you Medicine or electroplating business of a result.

       The first result is hydrochloric acid acid mist inhibitor, the cost of a ton of acid about 13 dollars. The contents of the meeting can see the contents of the conference.

The second non-wastewater coating pretreatment pottery, I heard that some enterprises of phosphating wastewater is not easy to achieve the current emission standards, this pottery agent does not need to wash, sprayed pottery or dipping After which you can directly dry the subsequent spraying, eliminating the need for water washing steps.

       For nickel-plated alloy or composite plating of the iron can be used to remove the iron ions in the bath.

       Another new product I have studied is a water-based, chrome-free, Dacromet anticorrosive coating that achieves the desired thickness by electrophoresis. It is water-based, there is no hexavalent chromium ion, the advantage is that hardness is more than we now Dacromet paint. Hope that some entrepreneurs use non-cyanide-free nitric acid.

       Aluminum oxide alkaloid antifogging agent relative to hydrochloric acid antifogging agent, the role is to inhibit the evaporation of alkali fog, fogging rate is 90% or more. Alkaline agents also have the advantage of ensuring high dimensional accuracy of parts, in addition to the removal of aluminum oxide, and bare metal aluminum reaction, corrosion effect is very good.

If we are what you are on the iron parts, copper on the nickel electroless nickel plating, you can try to replace the electroless nickel-phosphorus plating nickel phosphorus, the difference is the need for an anode is metal nickel, the biggest advantage is that It can improve the use of electroless nickel-phosphorus cycle, to extend its service life.

       Chromium-free passivation treatment of new technology in Panzhihua Iron and Steel (Group) production line has been used, our school also has a teacher to do magnesium alloy micro-arc oxidation, the teacher is a foreign study abroad. Its research also has aluminum alloy micro-arc oxidation and chemical plating technology.

       This is the titanium alloy surface electroless plating on the surface, I also developed in the aluminum alloy above the process of cyanide-free zinc, our college teacher developed a new type of test paper concentration of the test paper. Finally, a product is developed this year, nickel-plated sealant.

       The results of the school can be the results of the transformation, if the results of the transformation of enterprises and universities, Kunshan government government to give 50% of the funding, but asked to apply these results to the production of them.
