Dicyclohexyl ammonium nitrite for antirust

1)VCI power with a long period of anti-rust. 2)Easy to use. 3)Reliable performance.

  In the field of metal protection, one kind of material is called as vapor corrosion inhibitors (VCI) that can volatile gases which can slow down metal corrosion under certain conditions through the role of vapor pressure. Dicyclohexyl ammonium nitrite has been the major categories of vapor phase anti-rust materials with reliable performance, long rust-proof period, simple operation, easy to use and so on.

1. Name

Dicyclohexyl Ammonium Nitrite [(C6H11) 2NH] HNO2    Molecular weight: 228

2. Characters

  White powder, amine odor, 175 (decomposition) of melting point, solubility in water at room temperature for 3.9 %, in methanol for 27 %, in 70 % ethanol aqueous solution for 16.7 %. Decomposing when it encountered strong acid and strong alkali. It is also easy to break down in the light and humid environment. Vapor pressure at 25 is mercury of 0.0002 millimeters. The evaporation rate increased at 75 . Combustible.

3. Uses

  There are good inhibition and rust-proof effects to black metal. It can be used for auto parts, decelerating speed chassis, internal combustion engine piston, sleeve, spare parts, machine tools and machine parts, tools, cutting tools, measuring, bearings, seamless steel pipe, machinery parts, textile machines and accessories, knitting machine needles, sewing needle, industry and civil blades, blades, aerospace mechanical, aircraft engines, steel wire, steel plate, steel strip, large-scale storage, packaging buckets, etc..

4. Applicability

  Slowing down corrosion and antirusting to steel, tin, nickel, chromium, aluminum, cast iron; accelerating corrosion to zinc, cadmium, magnesium, copper and its alloys.

5. Technical indicators

In accordance with JB/T6071 standards:

  Content:     > 95%

  Chloride:    <0.03 %

  Sulfate:     <0.04 %

  pH value:    7.5-8.0

  Solubility:   All solvent without the oil slick

  Gas Corrosion Test:       No corrosion to steel      SH/T0080-91

  Contact Corrosion Test:  No corrosion to steel      SH/T0080-91

6. Application

  VCI can be used in itself, also can be used through a variety of carriers by different forms to meet the different needs.

6.1 Direct method: Scattered into metal surfaces or internal of containers by direct use of corrosion inhibitor powder or bagging it, being made of films, balls, spindles (adding a small amount of adhesive, active agent) etc.; It also can be suspensed, placed in different parts of machinery and equipment. Generally effective range is not greater than 40 cm, and dosage is not less than 50 g / cm3.

6.2 Solid vectors: Coating on paper, plastic film, cloth, cardboard as a packaging material, or mixed with the molecular sieve desiccant to play a role in hydrophilic, moisture proof, at the same time play a role in anti-rust; It was made of cushioning and antihunting packaging by being mixed with particles of foam to play a role in anti-rust.

6.3 Hydrosolvent vectors: It was made of VCI water by dissolving in water to clean, soak, do pressure test and anti-rust between processes; To be made of VCI cutting fluid; It also can be made of VCI spray by dissolving in volatile solvents.

6.4 Oil vectors: Added in the lubricating oil, anti-rust oil, cutting oil to play an anti-rust role.

6.5 Other vectors: Added to substances such as adhesives and resins to be made of VCI belt, peelable plastics, etc..

7. Packaging and storage  Packaging: Carton board, 20 kg (Divided into 20 plastic packages).  Storage: Indoor treasury.
