Heavy Push | Refuse Acid Washing, Efficient Neutral Rust Removal, No Flash Rust, Continuous Metal Protection

Preface

According to a survey by the International Association of Corrosion Engineers (NACE), the global annual losses due to metal corrosion amount to $2.5 trillion, equivalent to approximately 3.4% of the global gross domestic product; The hazards of corrosion are widespread in all industries, such as chemical, energy, transportation, machinery, infrastructure, and many others.

Metal corrosion mainly comes from chemical corrosion and electrochemical corrosion. Chemical corrosion is the corrosion of metals caused by contact with oxygen, water, and other corrosive chemicals, resulting in the oxidation of metals. Electrochemical corrosion is caused by the formation of a water film on the surface of a metal object, which dissolves substances such as oxygen and carbon dioxide, thereby forming a primary battery with a negative potential on the metal, accelerating the corrosion rate of the metal.

1. Multiple options for rust removal

Generally speaking, there are two common rust removal methods: mechanical rust removal and chemical rust removal. Mechanical rust removal mainly involves physical methods such as grinding and sandblasting to remove rust. Traditional rust removal is mainly achieved by dissolving iron rust with acid.

2. Professional rust removal product LA CT 101

LA CT101 is a sulfur-containing neutral rust remover with excellent rust removal efficiency. Chemical reactions can quickly occur on the surface of metal oxides to achieve rapid rust removal.

△ LA CT 101 Physical Characteristics

01. Only reacts with metal oxides

02. The pH is neutral, so it will not corrode the metal itself

03. It has excellent anti flash rust effect and the metal surface will not appear blackened after rust removal

3. Comparison of rust removal test results

#01 Rust removal effect of galvanized sheet

Spray rust removal onto the surface of the rusted galvanized sheet, wait for 1-2 minutes, and then observe the surface of the test piece.

The test results show that after 1-2 minutes, the rust on the rusted test piece significantly reduces, achieving the rust removal effect;

#02 Cold rolled iron plate rust removal effect

Soak the rusted iron sheet directly in rust remover, wait for 1-2 minutes, and observe its surface condition.

The test results show that the first image on the right is taken out and wiped dry with a tissue after immersion rust removal, the middle image is washed with water and wiped dry after immersion rust removal, and the third image is directly rinsed with water and naturally dried after rust removal;

After rust removal and drying, the iron sheet will not rust back even after being placed in a normal environment for half a month. However, if it is directly washed with water after rust removal and not dried, it will quickly rust back.

#03 Horizontal comparison of rust removal effects among competitors

Place the test piece into two experimental samples with a concentration of 30% and observe the surface changes.

The test results show that the competitor on the left not only removed rust but also caused significant blackening on the surface of the iron sheet;

The product on the right can achieve good rust removal and flash rust prevention effects, and the metal surface will not appear black or other phenomena after rust removal.

4. Summary of Advantages of LA CT101

01 High rust removal efficiency

For common materials such as iron sheets and galvanized parts, it only takes 1-2 minutes to achieve the desired rust removal effect;

02 Rust removal and durability

After rust removal, it is not easy to experience rusting and the metal surface should be kept clean for a long time;

03 Easy to operate

Simply soak or spray this product directly on the rusted area to easily remove rust stains;

04 Green and Environmental Protection

No harmful substances are generated during use, and the liquid after rust removal can be safely discharged to ensure environmental safety.

Main applications

This product is mainly designed for rust removal of various metals such as precious metals or precision instruments (rust remover will protect the metal itself from corrosion and only react with metal oxides)

5. Product usage precautions

1. No need to add water (adding water will slow down the rust removal efficiency);

It is recommended to soak the rust removal of 2 small workpieces directly in LA CT101, and the rust can be removed in a few minutes;

For rust removal of precision instruments or large workpiece equipment, it is recommended to spray rust remover directly on the surface of the rusted area. After about 1-2 minutes of reaction, rinse it off with water and dry the rusted area before taking rust prevention measures (wiping off surface water stains. Under normal conditions, there will be no flash rust on the metal surface within half a month).
