Embodiment 1
[0045] see Figure 1-6 , a new rust removal process based on nanobubble technology, including a sealed box 1, see Figure 1-2 The inner walls of both sides of the sealed box 1 are equipped with nano-bubble generators 2, the upper and lower parts of the sealed box 1 are equipped with electromagnets 3, the inner wall of the sealed box 1 is fixedly connected with a support plate 4, and the support plate 4 is close to the bottom The electromagnet 3 is characterized in that: the sealed box 1 is filled with a rust remover, and a plurality of rust remover balls 5 are placed in the rust remover; it includes the following steps:
[0046] S1, first put the workpiece to be derusted on the support plate 4, and then cover the sealing cover of the sealing box 1;
[0047] S2, filling inert gas into the sealed box 1 to discharge the air in the sealed box 1;
[0048] S3, inject the derusting agent into the sealed box 1, and finally put the derusting ball 5 into it.
[0049] see Figure 3-4...

The invention discloses a novel rust removal process based on a nano-bubble technology, and belongs to the technical field of rust removal. The novel rust removal process based on the nano-bubble technology comprises a sealing box, removes dust by utilizing ultrasonic waves and impact force generated when nano-bubbles are broken, can achieve a good rust removal effect, and is particularly suitablefor workpieces with uneven surfaces; an electromagnet is used for controlling rust removal balls to move up and down, so that the rust removal balls can carry nano-bubbles, furthermore, the rust removal balls are enabled to impact the surface of the workpiece by means of adsorption force of the electromagnet, a rust layer can be removed in a physical impact mode, extrusion force can be applied tothe nano-bubbles to promote the nano-bubbles to be broken, and therefore, the rust removal speed and efficiency are increased; and in addition, the removed rust is adsorbed through adsorption rods, so that the rust is prevented from being accumulated in a large amount in a rust remover, the rust removal effect is further improved, and compared with the prior art, a better rust removal effect canbe achieved and the equipment is simple in structure, low in investment cost and high in efficiency.
Description
technical field [0001] The invention relates to the technical field of rust removal, and more specifically relates to a novel rust removal process based on nano-bubble technology. Background technique [0002] Nanobubbles refer to bubbles with diameters ranging from tens of microns to hundreds of nanometers when bubbles occur. This kind of bubbles is between microbubbles and nanobubbles, and has physical and chemical characteristics that conventional bubbles do not have. The dissolution of nanobubbles in water is a process in which bubbles gradually shrink. The increase in pressure will increase the dissolution rate of gas. With the increase of specific surface area, the speed of bubble shrinkage will become faster and faster, and finally dissolve into water. Theory The pressure suffered when the upper micro-nano bubbles are about to disappear is infinite. When the nanobubbles burst, they can generate ultrasonic waves at a speed of about 400 kilometers per hour. [0003] T...
