Magnesium alloy building template full-liquid-state die casting and bifluoride combined manufacturing method

The invention discloses a magnesium alloy building template full-liquid-state die casting and bifluoride combined manufacturing method. The method comprises the following steps that 1, a magnesium alloy building template is prepared by adopting a full-liquid-state die casting method; and 2, the magnesium alloy building template prepared in the step 1 is immersed into a bifluoride treatment solution for bifluoride combined treatment, and the magnesium alloy building template subjected to bifluoride combined treatment is obtained. The magnesium alloy template manufactured by the method is flat and free of defects, high in tensile strength, large in elongation, high in surface hardness, small in friction coefficient and excellent in scratch resistance and hydrophobicity, friction damage caused by concrete aggregate and corrosion damage from external erosion media can be effectively reduced, chemical reaction and physical adsorption caused by cement are prevented, and the construction quality and the demolding ef
