corrosion inhibiting clinic

1. What is VCI?
Volatile Corrosion Inhibiting
Simply put, VCI is Volatile Corrosion Inhibiting. At room temperature, it utilizes emission of rust-inhibiting vapor that dissolves in water in the open air for inhibiting "rust" from electrochemical reaction.

The reason for causing corrosion on steel, based on electrochemical theory, is the ionization of metal which generates anode and cathode. Zerust corrosion-inhibiting series of products are leveraging chemical NI-22790 to inhibit ionization on anode and cathode for inhibiting corrosion. It has unique buffering system for gradually neutralizing acid level to maintain a PH value of 4.5 ~ 10.5. This produces significant inhibiting effects on corrosions rooted from sulfide gas, chlorine, ammonia, and salt.

2. What are the differences between using anti-corrosion oil + plastic bag and anti-corrosion bag?
Poor-quality anti-corrosion oil will dissolve under high temperature and cannot achieve corrosion prevention results. When anti-corrosion oil gets dry, the plastic bag will get suck with anti-corrosion oil causing oil stain on the surface of products and result in inconvenience during manual assembly. The anti-corrosion bag does not have such deficiency so that your products will be delivered to customer site AS IS.

3. What is the applicable life cycle for Anti-Corrosion Bag?
The applicable life cycle for using anti-corrosion bag is one year.
(The life cycle for the material is 5 years.)

4. There are many anti-corrosion products on the market, what are ZERUST’s differentiations and advantages?
All of our products have passed FDA & RoHS and local Inspection Bureau’s quality approvals. We also have partners in more than fifty countries so that they can quickly help resolve arguments related to corrosion and corrosion prevention between importing and exporting countries to professionally address customers needs with quality services.

5.What Zerust product categories are tailored for packaging different materials?
Our anti-corrosion products are categorized into “Ferrous”, “Non-ferrous”, and “Common”. They are used to package different materials.
