What criteria do we use in choosing our anti-rust oils?

.................................................................................................................................................................
Just because an anti-rust oil is long-lasting, doesn't necessarily make it the most appropriate one to use for rust-prevention on every kind of part. First, we must have an understanding of the entire production process. What parts, for example, is the anti-rust oil need for? What is the speciality of their material? How long must be they rust-free? Where and in what manner are they to be maintained? How are they handled, pre- and post-production? It is only after consideration of these various conditions that we can recommend the anti-rusting product most appropriate for our clients’ needs.

Why are anti-rust oils (or pressing oils) necessary during the manufacturing process?

.................................................................................................................................................................

1.   To keep the parts from scraping and being damaged
2.   To prevent wear and tear in the molds, extending their lifespan.
3.   To cut down on friction, enhancing precision.
4.   To reduce work-time.

What are the effects of improperly regulated concentration and PH in water-soluble cutting agents?

.................................................................................................................................................................
1.     Problems from poorly regulated concentration.
Over-Concentrated Under-Concentrated

1. Failure to attain sufficient cutting coarseness.
2. Excessive scrap during production.
3. Secondary emulsification of operation oil.
4. Unpleasant odors resulting from the over-concentrated oil products themselves
5. Skin irritation.
6. Frothing.

1. Shortened lifespan of cutting tools.
2. Rusting of the machine parts.
3. Inferior production.
4. Bacteria growth.
5. Mold and mildew.


2.     Problems from poorly regulated PH
High PH Low-PH

1. Corrosion of non-irons.
2. Separation of thinners.
3. Erosion of coating.
4. Skin irritation.

1. Iron rust
2. Graying of thinners
3. Bacteria and fungus growth

What are the functions of pickling inhibitor?

.................................................................................................................................................................
1.Corrosion prevention in steel-based materials………fights off wear and tear, improves the appearance of steel, slows corrosion
2.Saves on acid usage…………………………………less acid needed than before.
3.Minimizes hydrogen production……………………less acid, healthier work environment
4.Inhibits hydrogen from infiltrating the steel…………less hydrogen-induced fragility
5.Efficient use of acid…………………………………less steel dissolved by the pickling solution
