Cleaning of molybdenum wire and molybdenum alloy wire
Molybdenum wire or molybdenum alloy wire is the most widely used material for molybdenum products at present, which is mainly used in the fields of electron tube cathode, wire wound core wire, heating element and electrode wire for wire cutting processing. It is an indispensable material for wire products in the electronics industry and machining industry. Its processing technology is more complicated, the quality requirements of its products are also very high, requiring a higher purity and surface finish.
However, after repeated drawing machine, a large number of dirt remains on the surface of molybdenum wire or molybdenum alloy wire, such as the oxide film generated by heat treatment, annealing or strong acid and alkali corrosion, leaving remnants and water vapor; Lubricant (drawing powder, graphite milk) after high temperature, after drawing attachment, etc.
The current treatment includes all kinds of wire or the traditional simple alkali washing process, that is, molybdenum wire or molybdenum alloy wire soaked in a concentrated alkali tank, rinsed with high pressure water, and then dried on a wire rack. Using this process is difficult to completely remove the dirt attached to the surface of molybdenum wire or molybdenum alloy wire, and in the process of placing and drying molybdenum wire or molybdenum alloy wire directly contact with water and air, easy to occur again oxidation, did not achieve the purpose of complete cleaning decontamination and deoxygenation, with great defects, so it is urgent to develop new cleaning technology and new cleaning equipment for molybdenum wire or molybdenum alloy wire.
How to clean molybdenum wire and molybdenum alloy wire is more effective?
Alkali wash: Pass molybdenum wire or molybdenum alloy wire through alkali wash tank containing mass concentration sodium hydroxide solution;
Alcohol washing: after alkali washing, molybdenum wire or molybdenum alloy wire passes through the alcohol cleaning tank to remove the lye from the alkali washing tank;
Deoxidation: After alcohol-washed molybdenum wire or molybdenum alloy wire through the aeration chamber to deoxidize.
Cooling: The deoxidized molybdenum wire or molybdenum alloy wire of the tibia is cooled through the length of the cooling tube.
Our company can produce and process molybdenum wire and molybdenum alloy wire according to customer demand.
