Does the Amount of VCI Powder Work in a Humid Environment?
2025-09-07 17:02Anti-rust in a humid environment, is it useful to sprinkle more anti rust powder? In fact, it's not that the more, the better. The anti-rust effect of anti rust powder depends on whether it can evenly release the anti-rust ingredients in the sealed space, rather than relying on increasing the amount, choosing the right product and using the right method, even if the normal amount can have a good anti-rust effect in a humid environment.
The problem with humid environments is that there is a lot of moisture, which can easily speed up the oxidation and rust of steel. However, the principle of anti rust powder is to form a protective film on the surface of steel by releasing gaseous anti-rust components. As long as these components can fill the sealed space and cover the surface of the steel, moisture and air can be isolated. If you only increase the amount blindly, anti rust powder will accumulate, which is not only wasteful, but may also cause rust in some areas due to uneven distribution. There is no anti-rust component. What really affects the anti-rust effect in humid environments is whether the anti rust powder 's own formula can be used in high-humidity scenarios and whether the packaging is sealed. This is more important than the amount added.
The anti rust powder we produce has a finer particle size and a more uniform distribution. It can spread naturally after being sprinkled into the sealed space, and there will be no agglomeration or local accumulation. There was an export company that used our VCI powder for metal for anti-rust packaging of machine tool parts. It is used in conventional quantities. The parts are transported by sea in containers for 20 days, and there is no rust after unpacking, which meets the export requirements.
We will also provide VCI powder for metal dosage recommendations according to the specific scenarios of customers. For example, for cubic meters of sealed boxes, how many grams of powder will be recommended, so that customers will not be affected by improper dosage. Anti-rust effect.
We carry out the whole process from raw material mixing, grinding to dispensing in a dust-free workshop to ensure the purity and uniformity of VCI powder for metal. And we are equipped with a special laboratory. Our laboratory has passed the CNAS certification. The laboratory has a modern experimental space covering an area of 4,000 square meters and is equipped with more than 100 cutting-edge instruments and equipment, including high-precision chromatographs, spectrometer, etc. Before each batch of VCI powder for metal leaves the factory, it will be tested for rust prevention to ensure that the rust prevention effect is up to standard before delivery.
CVCI's VCI powder for metal normal dosage can also cope with humid environments, and professional dosage guidance can make anti-rust work better. We will also continue to optimize our products so that the products we produce can better meet the needs of our customers.
