Problems solved by technology

Extrusion technology is difficult to realize the overall manufacturing of magnesium alloy templates, and the welding process must be used to manufacture field usable templates. However, due to the characteristics of the magnesium alloy material itself, it is difficult to achieve reliable template manufacturing with the existing welding process
Using the traditional die-casting technology to die-cast the magnesium alloy template, it is easy to cause the problem that the gas in the mold cavity and the gas generated by the die-casting coating in the template cannot be discharged smoothly. These gases either dissolve in the magnesium alloy under high pressure, or form many high-pressure micro-pores to disperse. Distributed within the die-cast formwork
[0005] In addition, the magnesium alloy die-casting formwork is easily corroded by the atmosphere and water environment during storage and use, and the surface of the formwork is easily scratched and damaged by concrete during construction. The surface quality of concrete molding; and the existing surface treatment methods are difficult to effectively solve the problems existing on the surface of magnesium alloy building formwork

Abstract

The invention discloses a semi-solid die-casting and double fluorination joint manufacturing method of a magnesium alloy building formwork, comprising the following steps: step 1, preparing a magnesium alloy building formwork by using a semi-solid die-casting method; step 2, using the magnesium alloy building formwork prepared in step 1 Immerse in the double fluoride treatment solution to carry out double fluoride combined treatment to obtain a double fluoride combined treated magnesium alloy building formwork. The magnesium alloy formwork plate produced by the present invention is flat and free of defects, has high tensile strength, high elongation, high surface hardness, small friction coefficient, excellent scratch resistance and hydrophobicity, and can effectively reduce the risk of concrete aggregates. The friction damage and corrosion damage from the external erosive medium prevent the chemical reaction and physical adsorption caused by cement, and ensure the construction quality and demoulding effect of the building wall.

Description
