Application scope:

Clean rust and slag in equipment made of mixed materials such as cast iron, carbon steel, stainless steel, copper, titanium, nickel, alloys, etc. Dissolve metal oxides.

Product Features:

Efficient rust remover can restore the original color of the metal. Rust, pollutants (carbon deposits), and oxides can be removed in a short period of time. No damage to the base material, can clean the surface of * * * components. Chemical drugs used as food additives can be used with confidence. It can significantly reduce the generation of exhaust gas. Prevent environmental pollution. Rust and other substances can dissolve automatically and also have an effect in fine crevices. It can be effective at room temperature without the need for heating. It will not affect plastic, rubber products, or painted areas. No flammability or explosiveness.

Usage:

Reasonable concentration and cleaning time should be selected based on factors such as corrosion degree and thickness, and can be diluted 1-5 times for use. This product is a concentrated formula that still has good effects on floating rust when diluted more than 20 times. Immersion, immersion, painting, spray, forced circulation and ultrasonic cleaning can be used. Manual scrubbing and derusting have better effect. It usually takes 10 minutes to clean up.

Packaging and storage: 5kg, 25kg, 200kg plastic drums.

Engineer's suggestion:

Increasing the concentration appropriately can improve cleaning ability and shorten cleaning time. If there is white sediment, shake it evenly before use.

During transportation and storage, it should be protected from direct sunlight and stored in a cool and dry place.

Efficient rust remover is biodegradable. If accidentally splashed into the eyes or hands, rinse immediately with clean water.

Wear protective goggles and rubber gloves during manual cleaning to avoid splashing into the eyes.

Metal surface rust remover

Overview

Metal surface rust remover is composed of * * * rust remover and high-efficiency corrosion inhibitor. It can quickly remove rust without causing corrosion to the material of the workpiece, and can be used as an environmentally friendly substitute for hydrochloric acid and sulfuric acid.

Product Features

The rust removal effect is rapid, which can quickly remove rust spots on the metal surface. It can also penetrate and dissolve sediments such as carbonates (such as scale), and decompose and detach other insoluble substances during the reaction process.

There is no smoking phenomenon or danger in use similar to concentrated hydrochloric acid.

purpose

Metal surface rust remover can quickly remove rust spots on black metal surfaces, copper, iron, marble, ships, electroplated parts, bicycle chains, agricultural tool parts, mechanical equipment and components, * * * metal products and components, etc.

Usage:

You can use soaking, scrubbing, or spraying methods, soaking method.

After rust removal, rinse the residue with a large amount of water. If rust prevention is required after rust removal, rinse with a large amount of water, neutralize and passivate with a 5% solution, wipe dry, and then spray rust inhibitor for protection.

Construction method:

Before using metal surface rust remover, the product must be stirred evenly (without diluent), and loose floating rust, broken oxide skin, welding slag, soil, oil stains, etc. on the steel surface should be removed before painting.

Brushing this product is different from general paint brushing. It is advisable to first brush horizontally and then vertically, with thin rust and light rust, and thick rust, without omission. If there are obvious brush marks and pinholes, they should be repaired in a timely manner. If white bubbles appear on the coating, they should be immediately wiped off with cotton yarn, and then lightly wiped with cotton yarn dipped in a small amount of alcohol to reduce residual acidic substances on the surface and not affect the quality of rust prevention.

This product should not be used for construction in rain or snow, and should be protected from water for 24 hours. If exposed to moisture, white powder will appear, which can only achieve the purpose of rust removal. After 24 hours of natural drying, it must be repainted.

After the processed material is dried, it can be painted or coated with rust proof oil.

The steel surface that originally required two coats of anti rust primer can be reduced by one coat of anti rust primer after applying this product.

The use of metal surface rust remover alone not only has good anti rust effect (with anti rust effect in a short period of time), but can only fully exert its anti rust effect when combined with other coatings. When used in conjunction with anti rust primer, it can be matched with various red lead primers, oil-based paints, alkyd resin paints, etc. The matching of asphalt primer is generally suitable, while the matching of epoxy resin paint and chlorinated rubber paint should be noted. Inorganic zinc rich paint is prohibited.

Non corrosive rust remover

Product Features

1. Efficient: Uniform rust removal * * *, strong removal ability for impurities such as rust and oxide scale on the surface of steel. Rust removal and prevention are completed in one go without generating secondary floating rust.

2. Long rust prevention period: After rust removal, the rust prevention period of steel parts in a ventilated and dry place is about one month.

3. Safety: Non flammable, non explosive, * * *, no acid mist, good corrosion inhibition effect on steel and iron parts.

4. Environmental Protection: Water based products, free of heavy metal ions, environmentally friendly.

5. Energy saving: No heating required for use at room temperature.

Scope of application

1. Non corrosive rust remover is suitable for rust removal and anti-corrosion treatment of various steel products such as steel plates, steel pipes, and steel bars before use.

2. Painting and rust removal of various steel components, steel machinery equipment, facilities, and containers.

Product***

1. Non corrosive rust remover is an environmentally friendly product. Compared with acid washing, it greatly reduces acid mist and pungent odor, fully inhibits the volatilization of acid, improves the working environment and reduces air pollution. Rust removers do not contain toxic or harmful substances, nor do they produce toxic or harmful emissions. The amount of discarded rust removers produced after recycling and comprehensive utilization is smaller. The operating temperature is -10~35 ℃ at room temperature, and the operating temperature is 10~30 ℃.

2. The rust removal and cleaning effect is good. The surface quality of rust removal and cleaning can reach ≥ Sa21/2, without the formation of black film, presenting the true appearance of the steel. Due to the clean and efficient cleaning, the adhesion and smoothness of the coating can be improved after coating.

3. Compared with acid pickling, non corrosive rust removers can improve the quality of steel. During the rust removal and cleaning process, there is no occurrence of "hydrogen embrittlement" or "over corrosion". Even if immersed in rust remover for a long time, there is almost no "weight loss" phenomenon, which protects the original mechanical and processing properties of the steel. Therefore, compared with acid washing, the mechanical properties of steel processed with rust removal solution have been improved.

4. Reduce labor intensity and save * * *. Compared with traditional pickling methods, using rust removers can greatly reduce labor intensity. Due to the fact that rust removers can extend their service life several times compared to the original pickling process and can be used for * * *, the unit weight of * * * can be reduced. Moreover, rust removers can be recycled (with the addition of additives) and comprehensively utilized, so through comprehensive calculation, * * * will not increase the cost compared to the original pickling process.
