Abstract
The invention discloses non-corroding ultrasonic cleaning equipment. A rust remover for ultrasonically cleaning a metal mould is used for rapidly and completely removing rusts on the surface of the metal mould, generating a dense and complete passivation film at the same time and avoiding a secondary oxidization. The rust remover is prepared from the following raw materials by mass percent: 8-30% of phosphoric acid, 6-25% of room-temperature steel surface conditioning agent, 1-4% of citric acid, 1-5% of tartaric acid, 1-4% of phytic acid, 1-8% of polyethylene glycol, 1-3% of penetrant JFC, 1-6% of ethylene glycol monobutyl ether and the balance of water. A preparation method of the rust remover comprises the following steps of: firstly, adding water with a calculated amount into a stainless steel reaction kettle, starting an agitator and controlling a rotary speed of the agitator to 40-60 r/min; then respectively taking the calculated amount of the phosphoric acid, the room-temperature steel surface conditioning agent, the citric acid, the tartaric acid, the phytic acid, the polyethylene glycol, the JFC and the ethylene glycol monobutyl ether and sequentially and slowly adding the materials into the reaction kettle; and adding the materials while agitating until the solution becomes a light-green transparent liquid.
Description
Technical field
The present invention relates to a kind of metal die ultrasonic cleaning rust remover and preparation method; Especially a kind of ultrasonic cleaning apparatus that do not corrode; Can rapidly, thoroughly remove the metal die surface corrosion and generate closely complete passivation epithelium simultaneously, avoid the metal die ultrasonic cleaning rust remover and the preparation method of secondary oxidation.
Background technology
Metal die is in the courses of processing such as compacting plastics, Al-alloy products, Zinc-alloy; Because the erosion of corrosive medium in high temperature oxidation, wear-out failure, the damp atmosphere; The antirust oil film on its surface is destroyed; So the metal die surface produces a large amount of corrosions gradually, can have a strong impact on the surface quality of plastics and various alloy products, must carry out acid pickling and rust removing to metal die.Because the metal die structural shape is complicated, there are irregular cavity, big or small length hole, micropore, blind hole to reach
FolderSeam, and to the gap size of its moulding movingly in one's power the surface smoothness of workplace require very strict, so at present metal die is adopted the ultrasonic cleaning rust cleaning mostly.The dominant mechanism of ultrasonic cleaning rust cleaning is that the small complex that exists in the matting deruster is under action of ultrasonic waves; Vibration, growth and break suddenly in bubble disruptive moment, can produce up to thousands of atmospheric pressure; Its surging force is enough to make rust deposite broken; The localized hyperthermia that is produced, high pressure help to quicken the dissolving of rust deposite, reach the purpose of cleaning rust cleaning.Its technical process is: UW pre-washing rust cleaning → UW master cleans rust cleaning → UW rinsing → neutralizing treatment → antirust processing.Yet because existing metal die ultrasonic cleaning rust remover all contains hydrochloric acid, sulfuric acid or oxalic acid basically, adjuvant used in addition, inhibiter does not match, and causes existing following problem:
1. corrode the stainless steel trough body of ultrasonic equipment;
2. washing speed is slow, temperature condition is high, and halfway problem sometimes also can eliminate rust;
3. mould produces the excessive erosion phenomenon through after cleaning rust cleaning, and surface blackening not only can not expose the true qualities of metallic matrix, and mould changed dimensional precision, has destroyed surface smoothness, causes mould to scrap;
4. after mould process pre-washing rust cleaning and the main cleaning rust cleaning, the surface produces corrosion again because of secondary oxidation before the rinsing of entering UW;
5. although after cleaning rust cleaning, carried out antirust processing, rust-proof life did not reach three months.
Summary of the invention
The present invention is in order to solve the above-mentioned technical problem of existing in prior technology; A kind of ultrasonic cleaning apparatus that do not corrode is provided; Can rapidly, thoroughly remove the metal die surface corrosion and generate closely complete passivation epithelium simultaneously, avoid the metal die ultrasonic cleaning rust remover and the preparation method of secondary oxidation.
