Phosphating is a reliable way to make metal more hard, durable, reliable, resistant to corrosion, and to make its surface is even. All businesses have the reasons for applying this particular type of protection, as an additional anti-corrosion factor or even the only one, depends on the conditions of use of the product. “Lacover” paints perfectly fit any phosphating. All our powder paints need is a clean surface and the skillful hands of painters.<\/p>\n

In this article, we will talk about the different methods of this method.<\/p>\n

Needs<\/h2>\n

Coating with insoluble phosphoric acid salts has many advantages, these substances actually insulate the material. Salinity, humidity, temperature changes and other atmospheric phenomena cause enormous damage \u2014 in this case, the layer protects as best as possible. However, it is vulnerable to mechanical damage and aggressive chemicals. If the product must withstand friction, small abrasive particles of sand, dust, stones, etc., such a coating will not last long. Use phosphoric acid salts as a soil for powder paint \u2014 the most effective and universal way to protect against rust.<\/p>\n

Varieties<\/h2>\n

Each production has its own peculiarities of technological processes, therefore there are many different ways to apply insoluble salt to metal products.<\/p>\n

Hydroabrasive<\/h3>\n

The part is immersed in a 10% solution of potassium dichromate, heated to 70\u00b0C, and then in an organosilicon liquid with gasoline. When the gasoline component evaporates, drying is carried out at a temperature of 100\u00b0C for an hour.<\/p>\n

 <\/p>\n

Phosphating primers<\/h3>\n

On the market, you can buy special phosphating primers based on orthophosphoric acid. They cause passivation of the metal, that is, the formation of a layer of oxides on surface.<\/p>\n

Chemical treatment<\/h3>\n

For chemical treatment, use MAZHEF salt, dilute 35 grams for every liter of water and boil for 20 minutes. At the same time, it is necessary to monitor the level of acidity and adjust it. For crystallization, it is enough to leave the parts in water for 10-15 minutes. There are various types of application of MAZEF, with different compositions solutions.<\/p>\n
