cable news: the selection and application of copper antioxidants

there are a large number of oxidation products in the market,
many are 3 acids in proportion to synthesis,
a lot of nitrogen oxides are produced,
device for treating waste gas,
and will produce zinc corrosion,
strong damage to human skin and respiratory tract,
but after the treatment of copper shiny shiny,
it has been widely used in production.
similar additives manufacturers as well as shanghai ys additives factory,
its product n 1 also has a similar performance.
chunlan air conditioner, sharp air conditioner, refrigerator condenser,
copper pipe valve, lamp holder,
light cleaning technology of antenna rod and electronic diode,
this kind of cleaning process.
but this requires a high degree of accuracy,
no corrosion on the surface of the cleaning requirements are still far away,
for example, multi-layer pcb board, cnc processing parts, etc..
now to meet the requirements of the vast majority of manufacturers have the following points:
meet environmental requirements, do not produce excessive corrosion,
rapid addition of oxides, no large amounts of nitrogen oxides,
harmless to the human body, after the treatment of copper, such as bright color.
second, in addition to oxidation after oxidation products,
in theory, the copper ions and oxygen in the natural world effectively isolated,
can solve the problem of oxidation of copper and copper alloys,
such as electroplating, fuel injection, painting, passivation,
these methods can be used to solve the problem of copper after processing,
oxidation of products,
but not every process is suitable for the needs of customers,
some means of high cost,
the natural color of copper and its alloys cannot be reflected,
it has a great influence on the conductivity, the welding performance and the tin performance;
passivation treatment products will appear color, oxidation time is not long;
now more popular, the effect is the best anti oxidation film,
the main principle of the work is to prevent the oxidation of liquid into the surface of the copper ion
(thin, invisible to the naked eye),
and then wash the copper surface of the anti oxidation working fluid,
drying copper surface water can be,
a uniform protective film is formed between the electrolyte and the electrolyte,
can effectively isolate the oxygen in nature,
so as to prevent the oxidation of copper,
the advantages of this process are: long oxidation time,
low cost, bright color, conductive properties,
welding properties, tin properties are not affected.
