Embodiment 1
[0038] like figure 2 As shown, a production system for passivated pure calcium cored wire in this embodiment includes a heater 1, an extruder 2, a cored wire unit 8, a passivation processor 3 and an automatic filling mechanism. Wherein, the heater 1 is located at the feed end of the extruder 2, the inlet end of the passivation processor 3 is located at the discharge end of the extruder 2, and the outlet end of the passivation processor 3 is provided with a core wire unit 8, the pure calcium cored wire to be processed passes through the heater 1, the extruder 2, the passivation processor 3 and the cored wire unit 8 in turn, wherein the above-mentioned extruder 2 is used to extrude the calcium rod into calcium Wire, passivation processor 3 is used to passivate the calcium wire. A liquid inlet is provided on the upper part of the passivation processor 3, the inlet end and the outlet end of the passivation processor 3 are sealed soft joints, and the passivation processor 3 is us...
Embodiment 2
[0058] A kind of production method of passivation pure calcium cored wire of the present embodiment, its steps are:
[0059] Step 1. Preparation of passivation solution
[0060]The methyl silicone oil and talc powder were weighed according to weight percentages of 90% and 10%, respectively, and the weighed methyl silicone oil and talc powder were placed in a high-speed stirring tank and stirred for 30 minutes to obtain the required passivation solution, And it is packed into passivation processor 3 and passivation liquid storage tank, the alkalinity PH of gained passivation liquid is 6.5;
[0061] Step 2. Heating and extrusion of calcium rods into filaments
[0062] Start the production system of passivated pure calcium cored wire, heat the pure calcium rod to be treated with heater 1, when the calcium rod is heated to the plastic extrusion temperature, put it in the extruder 2 for extrusion treatment , to extrude it into a metal calcium wire of Ф7mm, and the mass fraction o...
Embodiment 3
[0069] A kind of production method of passivation pure calcium cored wire of the present embodiment, its steps are:
[0070] Step 1. Preparation of passivation solution
[0071] The methyl silicone oil and talc powder were weighed according to weight percentages of 95% and 5%, respectively, and the weighed methyl silicone oil and talc powder were placed in a high-speed stirring tank and stirred for 25 minutes to obtain the required passivation solution, And it is packed into passivation processor 3 and passivation liquid storage tank, the alkalinity PH of gained passivation liquid is 6;
