1. About VCI anti-corrosion

Metal corrosion refers to the process of conversion from metal to metal compounds,also the original mineral form, under the influence of the surrounding environment medium.Under normal circumstances ,the more energy the refinery of certain metal consumes,the faster the metal will be corroded . On the surface of metal that has not be treated, there exists little electron ion , which will form the movement from the high-energy area(anode)to the low-energy area (cathode) due to the atmosphere corrosion factors to from current.The current will convert the simple substance of metal into the corresponding stable compounds ,thereby generating corrosion.

2. what is the principle of VCI gas phase antirust?

VCI is the English abbreviation of Volatile Corrosion Inhibitor, which is prepared by special compounding technology and mixing It can ,separately or when being cohesive to proper carrier,directly gasify at ambient temperature and under mormal air pressure .This inhibitor can fill the mixed gas containing VCI antirust factors in any interstitial space of the operating unit by its adjustable continuous volatility in a sealed environment.The mixed gas will adhere to the metal surface when it touches the surface to from a compact protection film with thickness of one or more molecule.The protection film can effectively isolate the metal surface from moisture , oxygen and other harmful atmosphere corrosive factors and inhibit .The occurrence of electrochemical reactions resulting in metal corrosion so as to achieve the best antirust and anti-corrosion effects.

3. Applicable Metals:

Ferrous metal ,alloy steel ,cast iron ,copper,brass,bronze,plated metal,zinc and its alloy,chrome and its alloy,cadmium and its alloy,nickel and its alloy,thin and its alloy ,aluminum and its alloy,and other metal materials and their products.

4. The applicable scope of Rustoper-VCI products includes but not limited to:

.Various metal materials,including plates, extrusions and sheets;

.Multiple-metal components,aerospace devices and various parts;

.Parts and installation kit for automobiles and motorcycles;

.Various large-scale machinery,machine tools and heavy equipment;

.Motors,bearings,gears,all types of pipe joints,metal stamping parts;

.Electronical,electrotechnic,electrical appliance and electrical products and their installation kits;

.Components,parts and fittings of electromechanical devices;

.Medical equipment ,sophisticated machinery and equipment;

.Various hardware tools,power tools,measuring and cutting tools and tool¨

.Various castings,powder metallurgy products;

.Boiler,pipeline and other pressure container system,and their components and fittings;

.Various IC products and PCB products;

.Firearms,cartridge case,artillery and other military equipment,and their components;

.Other machined products and metal products for daily use;

5. What are the features of Rustoper-VCI products:

.VCI products possess overall antirust effect; all-round antirust without leaving any blind spot can be achieved no matter the metal surface is regular or not.

.VCI products are long in antirust period which (generally two to five years) may exceed ten years after special treatment.

.VCI products are easy to operation during which coating, oil removal and cleaning and other working procedure can be omitted ,so they may save labor and time,improve working efficiency and save cost.

.Unimolecule protective layer will be formed after VCI gasification,which will not damage the material of the metal products,without any side effect.

.VCI products boast excellent antirust performance, which can prevent the protected metal from rusting and corrosion even though the metal is in the high-corrosive atmosphere with high temperature,high humidity and high salt during ocean shipping.

.VCI products are not only applicable to ferrous metal,but also to the non-ferrous metal or the combination of both; effectively reduce the cost of customer purchasing and inventory.

.The products are extensively applied from single parts to the whole equipment;simply achieving the purpose of antirust.

.The products have high degree of transparency,enabling the protected articles to be dynamically visual.

.The products are sanitary,safe and green,being unharmful to human beings and the environment.

6. VCI Film And VCI Bags:

VCI plastic film and VCI bags are the new generation of creative hi-tech products based on the combination of the high polymer material and VCI antirust technology.After the film is used to pack and seal the articles for antirust , VCI contained in the film begins to sublimate and volatilize the antirust gas factors which diffuse and penetrate into the surfaces of the articles for antirust and adhere on them to form a compact protection film with the thickness of monomolecular to avoid the surfaces of the articles for antirust in contact with all factors inducing corrosion,thus the corrosion is effectively prevented.

Features/Advantages:

.The film performs excellent gas phase and contact antirust function,with good antirust effects and high cost performance.

.The film is clean ,harmless and non-toxic,so it is safe to environment.It passes SGS certification and meets ROHS directives.

.The articles for antirust may be used immediately with no need to be degreased and cleaned. Therefore,the film can save labor and time ,improve work efficiency and save cost.

.The film is extensively applicable,and may be used for either single part or entire equipment.
