Introduction to Sodium Linoleate PX-N98Y:

Sodium Linoleate is developed by Zibo Pengxin Chemical Technology Co., Ltd. through the reaction of sodium hydroxide with linoleic acid purified from soybean oil, using a continuous saponification method. It is a compound composed of hydrophobic and hydrophilic groups, belonging to an anionic surfactant. Its specific physical properties vary with changes in the alkyl chain length. The powder is soluble in water and possesses excellent lubrication, thickening, dispersion, emulsification, demolding, concrete water retention, foaming, and cleaning capabilities. It is used as a water-retaining agent, retarder, and foaming agent in concrete cement mortar to improve pumpability, as a saponification powder and lubricant in the metal drawing process, as a rubber release agent, and as a thickener in water-based latex paints and mineral flotation agents in industrial applications.

2. Used in the Saponification Process of Metal Processing----Saponification Powder

Phosphated workpieces are immersed in a sodium linoleate drawing lubricant soap solution, where the sodium linoleate reacts with the zinc phosphating film on the workpiece surface to form a zinc linoleate film and a soap film layer. This film increases the plastic thickness of the workpiece deformation zone, forming a lubricating film between the die and the processed material, significantly reducing heat generation and preventing metal sintering and adhesion. It acts as a friction-reducing medium and plasticizer between the die and the drawn part, improving the surface finish and processing accuracy of the drawn products, reducing wear between drawing tools and dies, and preventing damage. This product is easily soluble in water and can be easily removed from the workpiece surface, with no adverse effects on the heat treatment, annealing, or tempering quality of the product. Stearic acid can also be added to the saponification solution (the temperature of the saponification solution must be above 60°C) to enhance its friction-reducing and extreme pressure resistance effects.

Usage Method: Prepare a 1%-7% sodium linoleate soap solution for use.

The amount of stearic acid added should be within 30% of the mass of sodium linoleate.
