Multi-metal universal type, specifications and packaging methods can be customized according to customer requirements, suitable for various metal materials and their products between the process or storage and shipping of rust-proof and moisture-proof packaging - Qingdao Xiangyuan desiccant.

VCI is the English abbreviation of Volatile Corrosion Inhibitor, which is a corrosion inhibitor prepared by special synthesis process and compounding. It can be directly vaporized at room temperature and pressure, either alone or attached to a suitable carrier. In the sealed environment, through its own adjustable continuous volatilization, any space gap in the work unit will be filled with a gas mixture containing VCI anti-rust factor, which will adsorb on the metal surface when it encounters it, forming a dense protective film layer with only one or several molecules thick.

The protective film can effectively isolate the contact between the metal surface and moisture, oxygen and other harmful atmospheric corrosion factors, and inhibit the occurrence of electrochemical reactions that promote metal corrosion, so as to achieve the best anti-rust effect.

As for the vapor phase rust prevention, it is very useful, because it has many specifications and types, so it is basically needed by various industries, from military equipment and machines to parts. Because of the vapor phase rust prevention, it is easier to use than the conventional rust prevention method, and it is harmless to the environment and the human body, and will become the mainstream rust prevention product in the future.

Vapor phase anti-rust desiccant (Qingdao Jindun) is a product made by combining the natural mineral attapulgite and VCI gasification anti-rust substance. It has both the function of absorbing water and the function of preventing rust. It is a new concept that absorbs water using new technology materials.

Rust inhibitor, suitable for iron or non-ferrous metal packaging and other packaging projects that need water absorption and anti-rust function;

In addition, Qingdao Jindun also sells desiccant that does not contain VCI gasification anti-rust ingredients;

Second, the principle of the product.

1) Attapulgite moisture absorption principle: the adsorption depends on its large surface area, surface physical and chemical structure and ion state, which is divided into physical adsorption and chemical adsorption. The essence of physical adsorption is the adsorption of adsorbate molecules on the inner and outer surfaces of attapulgite clay through van der Waals force. Chemiadsorption is the formation of adsorption centers on the surface of attapulgite clay by chemical bonds between molecules.

2) VCI anti-rust principle: VCI anti-rust particles are automatically released on the metal surface to form a molecular thick protective film, preventing the current from flowing from the anode to the cathode, thereby inhibiting the occurrence of corrosion reactions, and at the same time, the anti-rust particles are combined with the internal oxygen molecules and water molecules to restrict their free activities, produce interlocking functions, and achieve the purpose of rust prevention;

3. Product advantages.

1) It has strong water absorption, which is 2-3 times the water absorption of silica gel desiccant;

2) The higher the temperature, the stronger the water absorption, and will not release water after saturation;

3) Mineral desiccant, non-toxic, tasteless, non-corrosive, does not pollute metal products;

4) Anti-rust particles can penetrate into all corners of the packaging, especially the inside of metal products that are difficult to apply anti-rust oil, and can deal with the corners that cannot be treated by general anti-rust agents, so as to achieve a better anti-rust effect;

5) It does not affect the characteristics of metal products, and there is no need to clean it in the later stage;

6) Our products do not need to be vacuum-packed, and can be simply sealed and packaged;

7) The materials used in VCI gasification products are food-grade chemical raw materials recognized by the FDA, and do not contain substances that are carcinogenic or mutated to the human body, so as to be safe, environmentally friendly and non-toxic; Qingdao Jindun is the largest production base of anti-rust desiccant in China.

1. Comprehensive anti-rust effect. Regardless of whether the metal surface is regular or not, it can prevent rust in all directions, leaving no dead corners.
