823 mold special anti-wear agent is one of the series of DJB 823 solid film protectant (national military specification GJB 1300 91) created by Professor Peng Daoru of Beijing Institute of Chemical Protection, Beijing University of Posts and Telecommunications. The product is corrosion resistant; has outstanding smooth function and Wear-resistance function; can improve the die life by 3~10 times; and the cost is low, the operation is simple, the cycle is short, and the effect is quick.
First, the product features
1. Organic composites: 823 anti-wear agents are two kinds of artificial organic compounds with special layout materials and smoothing agents associated with metal corrosion inhibitors. The composites are strong polar molecules with permanent dipole moments; The electrostatic field force and the coordination field force of the molecular end group are chemically linked with the empty trajectory of the metal atom; the contact force is 30~150 kcal/mol; the contact force between the molecules is 11~300 times larger.
2. Polar molecules: Polar molecules consist of head and tail; there are dense electron clouds in the head of polar molecules; the electrons with larger energy enter the metal outer surface. The empty trajectory forms a chemical bond with the metal atoms (covalent bond and coordination). Key); has a strong polarity. The entire molecule length is about 35~37Ã…
3. Effect mechanism:
a. Corrosion resistance: The metal appearance of 823 anti-wear agent; can form a layer of intact film. This film is made up of numerous polar molecules; it forms a solid film; it separates air and moisture. The medium touches the metal surface; it shows excellent corrosion protection.
b. Smoothness: The mutual movement of the two metals coated with 823 anti-wear agent is actually a conflict between the tail and tail of the polar molecule of the 823 anti-wear agent riveted on the metal surface; constitutes a conflict between non-metal and metal.
c. Abrasion resistance: The metal appearance of the 823 anti-wear agent can form a multi-molecular layout; usually 3 to 4 layers, thickness of about 200 Ã… (20 nm). If beyond 4 layers; 823 anti-wear agent molecules can not be placed; Adsorption layer. Multi-molecular layout of 823 anti-wear coating; composition conflict is the conflict between film and film; coated and uncoated with improved wear resistance 11.09 times.
d. Easy to use: 823 anti-wear agent process is simple; put the workpiece into the 823 solution after immersion for 1-3 minutes to remove and dry to form a fine dry film; thickness of about 1 ~ 2 microns. The film is not Affect the dimensional accuracy of the workpiece and the inherent physical properties.
e. Low cost: 500ml solution can be applied to the outer surface of 5~7 square meters; coating cost per square decimeter is about 0. 2~0. 5 yuan.
f. Widely used: 823 anti-wear agent process is suitable for all kinds of metal materials; not only in the appearance of steel products and in the powder metallurgy and cast iron parts, the thickness is uniform, finely arranged layer. Widely used in steel, cast iron, steel pipe, steel plate And the appearance of non-ferrous metals and non-metallic materials such as gold, silver and copper.
g. High contact strength: 823 anti-wear agent and metal base parts have high strength; no skin, no drop, no rust, not only adhere to the original mechanical function of the metal base; and increase wear resistance and corrosion resistance.
h. Uniform coating: 823 anti-wear agent coating is even and fine. Whether it is shallow hole, deep hole, inner wall of the pipe, product corner and other shapes, the appearance of the mess; can be evenly applied to the surface of the coating; no pitting, no porosity.
823 anti-wear agent can be satisfied with sixteen functional indexes such as smooth, wear-resistant, conductive, insulating, anti-wetting, anti-mold, anti-salt, anti-sweat, impact resistance, industrial atmosphere, high and low temperature resistance. The indicators have reached or exceeded the skills and functional indicators on the literature collected by the National Patent Office and the National Science and Technology Commission Information Center and collected by international patents; they are at the international advanced level.
