Environment-friendly wiping rust remover

Abstract

Belonging to the technical field of minimally invasive rust removal on metal surfaces, the invention, more specifically, relates to an environment-friendly rust remover. The rust remover is characterized in that: corrosion at places that cotton swabs, cloth strips, and cotton threads can reach can all be removed, and the rust remover also has a short-term antirust function, so that enough time can be acquired for long-acting anticorrosion treatment. The rust remover is especially suitable for corrosion and rusty spots appearing on some precision equipment, instruments and meters, and processed precision parts and components. Additionally, for the corrosion problem of some electroplated parts, the rust remover also can reach very good surface treatment effects. The rust remover disclosed in the invention is composed of the following components by mass: 5-15% of tartaric acid, 10-20% of citric acid, 1-5% of phytic acid, 1-5% of sodium salicylate, 0.1-0.5% of a surfactant OP-10, and the balance distilled water.

Description

technical field [0001] The invention belongs to the technical field of minimally invasive rust removal on metal surfaces, and more specifically relates to an environment-friendly rust remover. technical background [0002] Conventional metal derusting is carried out during the manufacturing process of the product. The rust, oxide scale, oil stains, etc. on the metal surface are cleaned by "immersion" or "spraying" to form a brand new metal surface, ready to be transferred to Subsequent passivation or phosphating, painting or swimming paint, electroplating, spraying and other processes. However, these existing rust removal products still cannot solve the rust and rust spots that appear again during the use of the manufactured products, especially precision equipment, instruments and meters, electroplating accessories, etc. (the rust cannot be removed by soaking). In production practice, we can only use the traditional treatment method and apply anti-rust grease to delay the ...

Problems solved by technology

It should be pointed out that in this invention, the specific composition of the surface treatment agent for steel at room temperature is not stated; polyethylene glycol has not given its molecular weight, and molecular weight is very important for polyethylene glycol. Molecular weight 400 is liquid and has Cleaning performance active agent, waxy with a molecular weight above 2000, often used in metal processing grinding fluid; the disadvantage of ethylene glycol monobutyl ether is that it is volatile and flammable, and it is not suitable for use in rust removers

And on the whole, this invention is still the traditional "soaking" treatment method used in the production of products, but on the basis of "soaking", the relatively advanced operating process of "ultrasonic" is added; "soaking" Usually it is for detachable metal parts, and no matter whether the surface of the metal parts is completely rusted or not, it needs to be immersed in the descaling solution; in addition, the cost of organic acid is high, and it should be used in the "soaking" descaling solution that is slightly rusted during treatment. Use, the timeliness of its use is short, and the amount of use is large, so the cost is high and it is wasteful
