1. Made use of to prepare nickel-phosphorus alloy covering elimination service on magnesium alloy
The thickness of magnesium alloy is two-thirds that of aluminum alloy and one-fourth that of iron. It is one of the lightest architectural steel products. Magnesium alloy likewise has the advantages of good machinability, high particular toughness, high particular tightness, great damping, and excellent thermal conductivity. It can change steel, light weight aluminum alloy, plastic and other parts, and has a wide range of applications in cars, electronics, aerospace and other fields. Application leads. Magnesium is a very energetic steel with a standard possibility of -2.36 V. Its deterioration resistance is exceptionally bad. As a result, magnesium alloy materials must be appropriately surface treated before use to boost their deterioration resistance. Amongst numerous surface treatment techniques, electroless nickel-phosphorus plating on the alloy surface is an irreplaceable surface therapy method when the surface layer is needed to have electric conductivity, thermal conductivity, and solderability. There are currently several conversations on the electroless nickel plating process on magnesium alloy surfaces. Nonetheless, the risk-free elimination of nickel-phosphorus alloy finishing on the surface of unqualified magnesium alloy is an unavoidable web link in the production procedure. Presently, there are couple of research study reports in this field.
CN201210135803.9 supplies an approach with reasonable formula, basic procedure and easy control, which can properly remove the nickel-phosphorus alloy layer on magnesium alloy parts with complex forms. The eliminated base is consistent and will not wear away or harm the magnesium alloy of the base. Nickel-phosphorus alloy plating elimination solution. The technical option embraced by the existing creation to address the above technical problems is: a nickel-phosphorus alloy coating elimination remedy on magnesium alloy, which is characterized because it is composed of nitric acid, hydrofluoric acid, cetylpyridinium bromide, and allyl sulfide. An aqueous option composed of urea and phytate, in which the web content of 68% nitric acid is 200-400ml/ L, the content of 40% hydrofluoric acid is 200-420ml/ L, and the web content of cetylpyridinium bromide is 5-20mg/ L, the web content of allyl thiourea is 5-15mg/ L and the web content of phytate is 5-15mg/ L. The removal solution of today development embraces a liquid service made up of nitric acid, hydrofluoric acid, cetylpyridinium bromide, allyl thiourea, and phytate. When made use of, the electroless nickel-phosphorus alloy coating can be eliminated at space temperature. The magnesium alloy components are directly taken into the solution of the present invention, and the withdrawal time is 10 secs to 3 mins. It can successfully remove the electroless nickel-phosphorus alloy covering on magnesium alloy parts, specifically the nickel-phosphorus alloy finish on magnesium alloy parts with intricate shapes. The gotten rid of matrix is uniform and the option will certainly not corrode or damage the matrix. Compared to the existing modern technology, the here and now innovation has a straightforward make-up and a sensible formula, and can properly get rid of the electroless nickel phosphorus layer. The elimination option of the here and now creation has the advantages of basic operation, easy control, low cost, and so on, and the elimination solution can be reused. It can be made use of for several elimination and repair service of unqualified nickel-phosphorus alloy layers in electroless plating on magnesium alloys. The creation is likewise appropriate to the elimination and fixing of unqualified nickel plating during electroplating on magnesium alloys.
3. Utilized to prepare an eco-friendly and effective rust prevention
Corrosion preventions have turned into one of the most reliable anti-corrosion technologies because of their ease of use, vast application range, low financial investment, and fast outcomes. CN201310747678.1 supplies an environmentally friendly and efficient rust prevention and a preparation method thereof. The prep work approach includes raw material preparation and solution steps, especially including:
A. Raw material prep work: Prepare bamboo leaf remove for later use, and prepare pickling fluid, allyl thiourea, Tween, quaternary ammonium salt, and salt iodide for later usage;
B. Preparation: Include bamboo fallen leave extract, allyl thiourea, Tween, quaternary ammonium salt, and salt iodide to the pickling solution according to the raw material ratio, stir and mix well to acquire the target substance.
The invention is based on bamboo fallen leave remove and allyl thiourea, includes surfactant Tween, quaternary ammonium salt, auxiliary agent salt iodide, and the remaining acid pickling fluid to prepare the pickling corrosion prevention, which has synergistic result. effect. The invention is safe, low-cost, highly versatile and can significantly inhibit the harsh impact of acid on metal products. It can be utilized for pickling steel and aluminum in not natural acid and organic acid, and can be utilized in petrochemical tools, boilers and pipelines. After cleansing, the rust prevention of the here and now development is pollution-free, risk-free and practical to utilize.
