What is the difference between rust inhibitor and rust inhibitor on the surface of stainless steel m

The way it works and the focus is different.

General rust inhibitors work by removing rust from metal surfaces and preventing metal surfaces from coming into contact with air and water.

Stainless steel rust inhibitor, because stainless steel itself is not easy to rust, pure air and moisture will not corrode stainless steel, so the stainless steel rust inhibitor mode of action is to improve the ability of stainless steel surface to resist salt spray erosion, in order to make up for the anti-corrosion weakness of many types of stainless steel.

Rust inhibitors and rust inhibitors on the surface of stainless steel metal materials are the same thing, and rust inhibitors are mainly used to prevent rust of steel. The problem of metal rust spreads throughout all industries, and metal rust will damage the performance of metal products, and even cause major failures to scrap equipment. Therefore, many products will do a salt spray corrosion test.

The formula of rust inhibitor is varied, and the formula of rust inhibitor produced by each manufacturer is not exactly the same, and the formula of different models and specifications or different uses of rust inhibitor produced by the same manufacturer is not exactly the same.

Antirust liquid is an industrial liquid injection preparation (commonly known as antirust agent), which is a water-soluble antirust solution; No volatile toxic substances are produced; Direct physical contact with the product is not permitted.

Rust inhibitors can be divided into rust inhibitors between and after the process, which are called rust inhibitors between processes and rust sealants (also known as sealants) after processes. The anti-rust process is generally divided into inter-process anti-rust and product sealing anti-rust.

One is to prevent rust on the surface, and the other is to clean up the rust on the surface.

There are two main types of oil-soluble anti-rust additives: water-soluble rust inhibitor and oil-soluble rust inhibitor, as the name suggests, the biggest difference between water-soluble and oil-soluble is that they are soluble in different media. The difference in nature leads to the difference in use.

Metalworking parts are easy to rust in the process of production, processing and transportation, which requires the use of anti-rust oil to form a thin film on the metal surface to prevent metal rust chemicals. The so-called rust is due to the action of oxygen and water on the surface of the metal to produce a mixture of oxides and hydroxides, rust is red, patina is green, and aluminum and zinc rust is called white rust. It is difficult for machinery not to contact with oxygen, moisture or other corrosive media in the air during operation and storage, and these substances will be electrochemically corroded and rusted on the metal surface, and the above substances must be prevented from contacting the metal to prevent corrosion.

Rust inhibitor is a kind of anti-rust product, and other types include anti-rust oil, anti-rust paper, etc.

1: The composition is different.

Volatile antirust oil is carefully formulated by specially selected volatile hydrocarbon compounds and a variety of antirust additives, with fast volatilization, good film-forming and anti-rust properties. Oil film anti-rust oil, the product is made of mineral oil with a high degree of refinement as the base oil, and added a variety of imported additives such as anti-rust and anti-oxidation.

2: The object of use is different.

Volatile anti-rust oil precision parts, suitable for the final anti-rust of steel workpieces after machining. The oil film is thin, more cost-saving, and is suitable for workpieces that are not cleaned and rust-proof and are directly used for assembly. Oil film anti-rust oil is suitable for large bearings, large workpieces, suitable for internal lubrication and anti-rust of machinery during storage, transportation and deactivation period, suitable for anti-rust and lubrication of mechanical gears and hardware fasteners.

3: The appearance of the oil film is different.

The volatile antirust oil film is thin, and the appearance is a colorless and transparent oil film; The oil film is anti-rust, the oil film is thicker, and the oil film is more sticky to the touch!

4: The anti-rust time is different.

The specific anti-rust time of volatile anti-rust oil and oil-based anti-rust oil needs to be determined according to the customer's salt spray test requirements, anti-rust requirements, and use scenarios.

Whether it is volatile anti-rust oil, oil-based anti-rust oil or other types of anti-rust oil, the specific selection and use should be determined according to their own processing workpiece, use environment, anti-rust cycle, and processing technology! The most important thing is to find a reliable anti-rust oil**.

There are many varieties of rust inhibitors, and the composition is not the same, but the working principle is the same.

That is, an insulating film is formed on the surface of the protective part to prevent the protected object from being oxidized.

Before using metal rust inhibitors, the metal surface should be cleaned of oil, oxide scale and other contaminants.

Before using the metal rust inhibitor, the dust liquid must be stirred to ensure that the components of the metal rust inhibitor are evenly distributed.

When using metal rust inhibitors, all parts of the metal are covered with metal rust inhibitors.
