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 continuous saponification. 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. It has excellent lubrication, thickening, dispersion, emulsification, demolding, concrete water retention, foaming, and cleaning capabilities. It is used as a water-retaining agent, retarder, foaming agent in concrete cement mortar to improve pumpability, as a saponification agent and lubricant in metal drawing processes, rubber release agent, thickener in industrial water-based latex paints, and mineral flotation agent.

1. Water-retaining agent, retarder, foaming agent for concrete cement mortar, improving mortar pumpability

Sodium Linoleate is used as a water-retaining agent, retarder, and foaming agent in concrete cement mortar to improve pumpability. It enhances the dispersion of cement and sand, significantly improves the plasticity and water retention of mortar, effectively prevents cracking, and increases cement strength. Its water retention property prevents the slurry from cracking due to rapid drying after application, while the retarding effect improves workability and extends operational time, enhancing post-hardening strength. Its excellent foaming ability reduces the weight per unit volume of mortar, decreasing cement usage. Closed-cell foam provides excellent waterproofing capability to concrete, making it an additive for waterproof mortar. It serves as a binder in plaster, gypsum, putty powder, or other building materials for tile, marble, and plastic decoration adhesion, enhancing bonding. Used in ceramic glazes and with enamel to improve adhesion and processability. In refractory mortar for firebrick or cast furnace materials, it improves plasticity and water retention. With superior performance and cost advantages, Sodium Linoleate is an ideal replacement for hydroxypropyl methylcellulose and other cellulose derivatives.

Usage: Add 0.8-1.5kg per ton of concrete cement mortar.

2. Used as a saponification agent in metal processing----saponification powder

Place phosphated workpieces into a Sodium Linoleate drawing lubricant soap solution. The Sodium Linoleate in the solution reacts with the zinc phosphate coating on the workpiece surface to form a zinc linoleate film and soap film layer. This film increases the plastic thickness in the deformation zone during processing, forming a lubricating film between the die and the material, significantly reducing heat, preventing metal sintering and adhesion. It acts as a friction-reducing medium and plasticizer between the die and the workpiece, improving surface finish and processing accuracy of drawn products, reducing wear between drawing tools and dies, and preventing damage. It is easily soluble in water and can be removed from the workpiece surface without adverse effects on heat treatment, annealing, or tempering quality. Stearic acid can be added to the saponification solution (temperature above 60°C) to enhance friction reduction and extreme pressure resistance.

Usage: Prepare a 1%-7% Sodium Linoleate soap solution.

The addition of stearic acid should not exceed 30% of the Sodium Linoleate mass.

3. Industrial Thickener

Sodium Linoleate is a water-based thickener made from natural plant oils, a high molecular biopolymer. Its thickening mechanism involves hydrophobic main chains associating with surrounding water molecules via hydrogen bonds, increasing the fluid volume of the polymer and reducing the free movement space of particles, thereby raising viscosity. It can also increase viscosity through molecular chain entanglement, exhibiting high viscosity at static or low shear and low viscosity at high shear. This is because, at static or low shear rates, the molecular chains are disordered, resulting in high viscosity, while at high shear rates, molecules align parallel to the flow direction, facilitating sliding and reducing viscosity. It is resistant to acids, alkalis, and high temperatures, dissolves well in cold water, viscosity increases over time, and is less affected by temperature. It adjusts rheology to thicken adhesives and sealants, prevents filler sedimentation, provides good physical and mechanical stability, controls workability during application, prevents sagging, dripping, or splashing, and reduces costs.
