Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide an environmentally friendly vitrifying agent, which is green and environmentally friendly, and does not produce sediment residues in the process of processing workpieces, and the waste water produced does not contain various heavy metals and does not contain phosphorus, zinc and nitrite Controlled harmful substances, the discharge of its waste water is non-polluting to human health and the discharge of the environment, and its processing speed on the workpiece is fast, the time required for film formation is short, and the cost of use is low. The workpiece after film formation is used The surface is golden yellow or blue-purple, and the surface of the workpiece is bright, smooth and dust-free. It not only has a good treatment effect on the workpiece, but the film layer is extremely thin, but it has a strong corrosion resistance. Its corrosion resistance is traditionally treated with phosphate. The corrosion resistance of the workpiece after phosphating treatment is more than 2 times that of the workpiece, and the whole operation process does not require heating, the bath has no slag and does not need to be filtered, and the operation is very convenient. Long processing time, too thick film on the surface of the workpiece, extremely poor corrosion resistance of the workpiece, high use cost, heavy metals, controlled harmful substances such as phosphorus, zinc and nitrite, a large amount of sediment, high wastewater treatment costs, The low recycling rate of wastewater and the serious impact on human health and the environment

Abstract

The invention provides an environment-friendly ceramization agent with low energy consumption and high performance. A titanium-zirconium compound is used as a foundation and special auxiliary agents are added so that the titanium-zirconium compound can be subjected to chemical reaction with surfaces of metal workpieces including steel, zinc plates, aluminum products and the like to generate a hybrid and difficult-to-dissolve nano ceramic conversion film; the environment-friendly ceramization agent has good corrosion resistance and impact resistance, and the attachment force of a coating can also be greatly improved; residues, various heavy metal substances and controlled harmful substances without phosphorus, zinc, nitrite and the like are not generated in a workpiece treatment process; the emission of wastewater has no pollution to health of human bodies and the emission of environment; the environment-friendly ceramization agent has a rapid treatment speed on a workpiece, and the time for forming a film is short; a film layer is extremely thin and the utilization cost is low; the environment-friendly ceramization agent has a good treatment effect on the workpiece and the workpiece has a strong corrosion-resisting capability; the corrosion-resisting capability is two or more times the corrosion-resisting capability of the workpiece subjected to phosphatizing treatment by utilizing phosphate in a traditional process; in a whole operation process, heating is not needed and tank liquid does not need to be filtered and precipitated.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to an environment-friendly ceramic agent. Background technique [0002] The principle of traditional phosphating solution film formation is that phosphate forms a layer of crystals on the surface of the workpiece, thereby increasing the adhesion and corrosion resistance of the surface of the workpiece and the coating. However, products that use phosphate for phosphating treatment have long phosphating treatment time (about 10 minutes), too thick film layer (about 2-3um) formed on the surface and coating of the workpiece, and extremely poor corrosion resistance (its corrosion resistance The spray time of 5% salt water is about 500 hours), the high cost of use (the slotting ratio is about 8%), and the lack of controlled harmful substances such as heavy metals, phosphorus, zinc and nitrite, etc. During the process, a large amount of sediment and heavy metal-containing wastewater will ...
