method of removing grease surface of titanium rod and titanium alloy rod
titanium materials are widely used in various industries, including chemical industry, petroleum, aerospace, ocean, common titanium screw and medical equipment in daily life. in particular, medical titanium rods are most widely used in the application industry. however, in the long-term use of titanium rods, there will inevitably be losses, especially in the chemical industry and medical field. in this 24-hour production and processing industry, the loss will be greater, oil will inevitably appear on the surface, so we need to deal with it in time. the methods for removing grease surface of medical titanium rod and titanium alloy rod are as follows:
in chemical industry and industrial engineering related to corrosive media, a large number of machines and equipment are corroded and damaged. it is estimated that hundreds of millions of tons of iron and steel are discarded by corrosion every year in the world, accounting for one tenth of the total output, and can not be recovered due to corrosion and loss. corrosion will not only discard a large number of metal materials, but also bring about environmental pollution and pollution. corrosion can also cause explosion and combustion, leading to catastrophic accidents.
before removing oil, droplets gradually rise and become reservoirs. chemical degreasing is related to electrodegreasing. it removes saponified oil by saponification of hot alkali solution and non-saponified oil by emulsification. saponification reaction is the alkaline reaction between animal and vegetable oils and sodium hydroxide to produce water-soluble soaps and glycerol.
in short, the necessary conditions for chemical degreasing are as follows:
advantages of cathodic degreasing:
1) electrolysis of 1 mole of water can produce 1 mole of hydrogen, and electrolysis of 2 moles of water can produce 1 mole of oxygen. when the same charge is applied, the volume of cattle gas produced on the cathode is twice the volume of gas produced on the anode. natural gas power generation is the main reason for oil-free electricity generation.
2) it does not corrode the workpiece. the hydrogen generated on the cathode has a recovery effect, so that the metal atoms on the surface of the workpiece will not be oxidized or lost electrons and dissolve from the workpiece in the ionic state. therefore, you have copper and copper alloys, zinc and zinc alloys (including die casting), you must use cathode to remove oil, otherwise you will become black or corroded.
