[0033] Aiming at the problems existing in the prior art, the present invention provides a method for preparing multi-core blendable metal fibers for X and gamma ray protection, such as figure 1 As shown, it specifically includes the following steps:
[0034] Step 1. Use an automatic winding machine to sequentially electrolyze the heavy metal wire through electrolysis, activation, preheating, and jointing to obtain a coated wire; the grooves are closely connected to prevent the metal wire from being exposed to the air for too long and reappearing on the surface. An oxide film is formed.
[0035]The heavy metal wire is one of the pure metal wires or alloy materials of tantalum, tungsten, bismuth, niobium, molybdenum and zirconium. The material itself has excellent X and gamma ray protection performance, and the wire diameter is 0.2-0.6mm.
[0036] Because heavy metal wires such as tantalum, tungsten, molybdenum and other materials are materials with excellent corrosion resistan...
Embodiment 1
[0059] A method for preparing multi-core blendable metal fibers for X and gamma ray protection, specifically comprising the following steps:
[0060] Step 1, first wipe the pure tantalum wire with a wire diameter of 0.4mm to degrease with alcohol, then clean it with deionized water, put it in the electrolytic cell, and wind the end on the winding machine for winding; the concentration of sulfuric acid in the electrolyte is 50g / L, phosphoric acid 50g / L, polyethylene glycol 0.05g / L, potassium sodium tartrate 15g / L, the balance is water; the current density is 40A / dm 2 , the time is 1min;
[0061] After that, the tantalum wire enters the activation tank for 30 seconds, the proportion of nitric acid in the activation tank is 20%, the proportion of hydrofluoric acid is 3%, and the rest is water;
[0062] The activated metal wire enters the preheating tank through the traction of the winding machine. The temperature of the preheating tank is 50°C and the temperature is kept for 30...

[0068] A method for preparing multi-core blendable metal fibers for X and gamma ray protection, specifically comprising the following steps:
[0069] Step 1. First, wipe the tungsten wire with a wire diameter of 0.6mm to degrease with alcohol, then clean it with deionized water, put it into the electrolytic cell, and wind the end on the winding machine for winding. The concentration of sulfuric acid in the electrolyte is 60g / L, phosphoric acid 70g / L, polyethylene glycol 0.08g / L, potassium sodium tartrate 15g / L, and the balance is water. The current density is 60A / dm 2 , the time is 1min;
[0070] After that, the tungsten wire enters the activation tank for 40 seconds, the proportion of sulfuric acid in the activation tank is 5%, the proportion of nitric acid is 15%, and the rest is water.
[0071] The activated tungsten wire enters the preheating tank through the traction of the winding machine. The temperature of the preheating tank is 70°C, and it is kept for 40s. The comp...
