PRODUCT DESCRIPTION

VCI Desiccant Rust Proof Desiccant


Product introduction

       

The VCI desiccant is a combination of natural mineral attapulgite and VCI anti corrosion material. It has both water absorption and corrosion proof functions. It is a new concept of new technology rust inhibitor, suitable for packaging of iron or non-ferrous metals, etc., which require water absorption and rust prevention;

In addition: our company also sells desiccant without VCI anti-corrosion component


The product principle


(1)Moisture absorption: Adsorption depends on its large surface area, surface physicochemical structure and ion state, and 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  by van der Waals force; chemical adsorption is the formation of adsorption centers on the surface of attapulgite by chemical bonds between molecules.


(2) VCI anti rust principle: VCI particles automatically release a molecular thick protective layer on the metal surface to prevent electric ion flowing from the anode to the cathode, therefore inhibiting the corrosion reactions, while rust particles combined with internal oxygen and water molecules. Molecules are combined with each other to limit their free movement,andachieve rust proof purposes;


Product advantages


(1)It has strong water absorption and is 2-3 times of water absorption of silica gel desiccant;


(2)The higher the temperature, the stronger the water absorption, and the water will not be released outward after saturation;


(3)Mineral desiccant, non-toxic, odorless, non-corrosive, and does not pollute metal products;


(4)The corrosion inhibiting particles can penetrate into the corners of package, especially for the metal products, the corner of which are difficult to apply by the anti rust oil, and can handle the corners which is difficult to treated by the general anti corrosion agent, hence achieving better effect of corrosion proof ;


(5)It does not affect the characteristics of metal products, and does not need to be cleaned later;


(6)Do not need vacuum packaging,sealed and packaged easily;


(7) The materials used in VCI rust prevention products are FDA approved food grade chemical raw materials, which do not contain substances that are hazardous to  human body, so that they are non-toxic,safe, and environmentally friendly;


Characteristics


1)Color: dark brown granular


2) Desiccant specifications: 10 g / non-woven bag, 30 g, 50 g, 80 g, 100 g, etc.
