Product Description
DHT Type Wire Drawing Powder
Solid lubricants are powdered lubricants used for dry wire drawing. Its composition is a variety of single metal soaps or metal soaps with some additives. Metallic soaps are metallic salts of fatty acids. Metal soaps used as lubricants require a high softening point and transfer temperature (the temperature at which the coefficient of friction suddenly rises), good wear resistance and pressure resistance. The commonly used metal soaps for wire drawing lubricants are sodium and calcium soaps. Sodium soap is caussoda and saturated fatty acid glycerin C17H35COO) combined sodium stearate C17H35OONa, is a water-soluble soap, easy to remove, suitable for medium speed and temperature rise is not too high dry drawing, or subsequent coating operation of steel wire drawing. Calcium soaps are calcium stearate made by combining calcium hydroxide or calcium oxide with glycerin stearate. Others include barium stearate, zinc stearate, aluminum stearate and other metal soaps. Calcium soap can form a thick lubricating film, has good extensibility and lubricity, so it is often the main component of solid lubricants. Calcium soap is insoluble in water and not easy to be washed away. It is not suitable for drawing steel wire before coating.| Technical Specifications | ||||||

| Features | 1 Having a good pressure resistance, under the higher tensile strength, the powder coating does not remove after tough squeezing. 2 having good thermal stability to bear high temperature, the powder does not decompose and coking metamorphism. 3. Strong ductility, after being subjected to shear force, it can be extended with the deformation and elongation of steel wire, and does not break, so that the steel wire deformation is uniform, and the mechanical properties will not decline due to the uneven local shear stress. 4 Good absorptivity, can ensure the lubrication layer adhesion and uniform distribution. The thickness of lubricating film at first pass is more than 0.15 microns. 5 With a good lubrication effect, it reduces the coefficient of friction to lower the heating from drawn wires and wire drawing dies, resulting in reducing power consumption and lessening the wear-out of wire drawing dies. 6 It is of non-toxic and harmless, no pollution to the environment, non-corrosive and easy to clean away. | |||||
