Electroplating rust remover, the easiest way to remove rust from electroplated metals

Similar to the cleaning agent you mentioned, the name and model of each factory are different.

I'll send you information for your own reference.

Xiamen Huatian metal surface treatment materials line, professional ** metal pretreatment materials, details can be called 0592-6387836 Mr. Huang.

The easiest way to remove rust from electroplated metal1Lime and salt: Sprinkle the salt over the rusty area, then squeeze out the lime juice and pour over the salt.

The more lime juice you have, the better, then let it sit for 2 to 3 hours before scraping off any remaining rust stains. 2.Use chemical rust removers:

There are many chemical products that can remove rust, most of which are made of phosphoric acid or oxalic acid, and they are harmful to the world. Therefore, before using chemical rust removers to treat the rust layer, it is necessary to take precautions. 3.

Grinding off the rust layer with an abrasive: This method requires a lot of effort, but it can effectively remove the rust layer. A screwdriver at home is great for rust removal.

What is a rust remover?

Generally speaking, the main function is to remove the rust on the surface of the steel bar, protect the steel matrix, and show the original color after use.

Why use a rust remover?

Because in the "Code for Acceptance of Construction Quality of Concrete Structure Engineering" GB 50204-2002, it is stipulated that "the steel bar shall be straight and without damage, and there shall be no cracks, oil stains, granular or flake rust on the surface." "So in order to meet the requirements for qualification, there are many rust removal products on the market.

What about those rust removers that are substandard products?

At present, the rust remover is searched on the Internet to find many products, some of which contain sulfuric acid, hydrochloric acid, nitric acid, phosphoric acid, complexing agent, water and other raw materials made of rust remover, these are unqualified products, the use of rust removers of these products will cause environmental pollution, great harm to human health, but also corrode the steel body, the use of strong acid to clean steel bars in construction is also expressly prohibited.

Which rust removers are qualified products?

Qualified rust removers are highly efficient rust removers prepared from raw materials such as a variety of organic acids (vegetable acids, citric acids and edible phosphoric acid), complexing agents, permeation agents, corrosion inhibitors, surfactants, water and thickeners.

The main features include high safety performance, no phosphorus, no volatile, no odor, non-toxic, non-flammable and explosive, efficient performance, thorough rust removal, no damage to the mother, water-free washing after rust removal, no impact on the follow-up process of post-treatment, environmental protection and high efficiency, pH neutral, waste liquid is also weakly acidic, no acidification reaction will occur, no heavy metal ions, waste liquid dilution can be directly discharged after simple treatment, can avoid the cost of customer wastewater treatment and labor costs.

Most of the steel bar rust removers sold on the Internet add hydrochloric acid in pursuit of rust removal effect, but hydrochloric acid is strictly prohibited in building codes. How to identify whether the steel rust remover contains hydrochloric acid, the first is to take a sample to the local quality supervision station or chemical research institute to test the hydrochloric acid content (or consult the earth steel bar rust removal company to provide technical support), and then to identify by the senses, the hydrochloric acid content is high with a pungent smell and the agent is yellow; Low content or use high-purity hydrochloric acid in the sun for a few minutes, the color of the agent quickly turns yellow. At present, there are some unscrupulous manufacturers selling steel bar rust removers containing hydrochloric acid, which seriously damages the interests of the steel bar rust remover industry, and it is recommended that users consider it carefully.

Rust remover is an organic acid, mainly composed of surfactants, organic acids, accelerators, corrosion inhibitors and deionized water and other materials, metal surface rust remover, is composed of strong rust removers and high-efficiency corrosion inhibitors.

With ammonium chloride solution, mainly based on its hydrolysis is acidic, it reacts with rust ferric oxide.

Rust remover is a weak acid solution, using the principle of acid corrosion, to remove rust, really help you look forward to it

Rub the metal with potato skins to wipe off the rust. If a silver spoon or other silverware is rusty, wipe it with toothpaste to make it shiny. Copperware, especially patina, is not only unsightly, but also prone to food poisoning.

To get rid of patina, you can use 160g of fine wood, 60g of fossil powder, 240g of wheat bran and pour about 50g of vinegar together, mix it into a paste, apply it to copperware, and after the wind dries, after the wind dries, the patina will be removed.

1. When the electroplating parts have the problem of rust, you can use a little toothpaste, apply the rusty position, and then wipe the surface of the electroplating parts with a clean rag. Or use a rag dipped in a little weak acid, wipe the surface of the electroplating parts, and then wipe it with a clean fine rag, so that the rust is gone.

2. Electroplating is the process of using the principle of electrolysis to coat a thin layer of other metals or alloys on some dusty metal surfaces, and it is a process that uses electrolysis to attach a layer of metal film to the surface of the gold cavity or other materials, so as to prevent metal oxidation (such as rust), improve wear resistance, conductivity, reflectivity, corrosion resistance and enhance aesthetics. Many coins also have electroplated outer layers.
