Why in-process rust should be with water displacement?

Why should in-process rust be with water displacement?

After the process of metal processing (turning, grinding, cleaning, etc.), the water content often remains on the surface of metal parts. And the moisture may be:

Water-based cooler additives, such as cutting fluids and grinding fluids; the water film after cleaning; condensation water formed by air humidity; and the hand sweat of operators.

At this time, the metal parts will go through the subsequent process of transfer, temporary storage, and waiting, and during this period, it's easy to corrode.

 

What is water displacing oil?

In metal processing, water displacement means the anti-rust preventive additive with the features of water displacement. It can exclude the moisture content, humidity, or water-based cleaning fluids on the metal surface and form a uniform protective film. This is helpful to effectively inhibit the rust by the connection of water, moisture, and oxygen.

Why metal process using water-displacing anticorrosive?

In the metal processing of turning, grinding, cleaning, etc, the metal surface often remains the cutting fluids, cleaning fluid, or condensation. If the antirust additive can not displace this moisture content, it will lead to the following questions:

1. The failure of forming a protective film: the water film prevents the direct connection between rust preventive oil and metal, which will cause the discontinuous protective film and lose its effect. The water film residue will become a channel for long-term connection of corrosive substances, like oxygen and chloride, and metal. This is easily to prone to pitting, surface rust, or rust quickly under high humidity and hot environments.

2. In the process of storage or transfer, if the humidity or remained moisture content is not displaced, it can not inhibit rust rust by the way of depending on covering with anti-rust oil.

3. Shortening the protective period: the rust preventive oil lacks water displacement; even if they appear to have good coverage initially, it can not provide long-term effective protection.

4. Influence the subsequent processing: the failure antirust of the metal process will cause surface rust, which influences the subsequent processing of assembly, electroplating, and spraying, and increases the rework cost.

 

To be brief, without water displacement, it can not let the real anti-rust oil connect with the metal, and the protection will fail.

 

Which rust preventive additive is suitable for the metal process?

 

In the metal processing of turning, grinding, cleaning, etc., the metal surface will retain moisture content, which is easily corroded and prone to failure.

Water-displacing rust preventive is a thin film water prevent rust inhibitor additive, which can protect precision parts. The formation of protective film on the metal surface can inhibit the formation and spread of corrosive substances to realize the aim of prolonging the device lifespan and promote the safety and economy during development.

 

Chorus is a professional anti-rust additive supplier in China, and we can provide you with different function rust inhibitor additives.

Rust Preventive Additive Chorus-2100 is used as a rust preventive concentrate to blend water-displacing rust oils that protect metal parts during manufacturing, assembly, and in-plant storage, which is an effective and economic anti-rust additive for short-period rust prevention.

 

The method of spraying or impregnating components to drain and dry metal parts provides a slightly oil protective film for metal parts. With its excellent anti-rust properties and lubricity, 2100 is beneficial to prevent metal from rusting and prolong equipment life span.

The chorus-2100 with its excellent water replacement, water separation, anti-stain, salt spray performance, and rust preventive performance can provide an excellent rust preventive film for ferrous metals and non-ferrous metals exposed in the corrosive environment.

At the same time, the water-displacing rust preventive significantly simplifies the production process that the producers no longer need to source, stor,e and blend multiple individual anti-rust additives. They can get the high-quality final anti-rust oil by diluting concentrated anti-rust into base oil or solvent.
