  • Calcium stearate dispersion is water-based calcium, also known by the name calcium stearate.Solid Content: 50 %Note: We also offer food grade, pharmaceutical-grade and industrial-grade calcium stearate. Calcium Stearate Emulsion: Calcium stearate The white powder has the molecular compound C36H70CAO4 and is not soluble in water. It can be used to make plastic auxiliary tools, waterproofing agents, and lubricants. Calcium stearate (calcium carboxylate) is divided into soap. It's a lubrican Aqueous calcium stearate dispersion containing 40 to 55 percent solids is a preferred starting material. Aqueous calcium stearate dispersions are typically prepared by reacting stearic acid with aqueous hydrated lime slurry in the presence of conventional, commercially available dispersing agents, such as polyethoxylated alkyl phenol or dialkyl phenol, e.g., polyethoxylated nonyl phenol or nonyl phenol. Although it is to be understood that the invention is not intended to be limited by any parti This invention provides a urea-free, high solids content aqueous calcium stearate dispersion suitable for use as an additive in paper or paperboard coating formulations. More particularly, this invention provides a urea-free aqueous calcium stearate dispersion having a solids content of about 60 to about 80 weight percent, the balance being water. The solids portion of the dispersion comprises from about 30 to about 55 weight percent of calcium stearate, from about 10 to about 60 weight percent Aqueous calcium stearate dispersions have long been used as additives in paper coating formulation, the calcium stearate imparting lubricating, leveling, and anti-dusting properties to the coating formulation. Since it is preferable in the paper-making industry to use as many pre-dispersed starting materials as possible to prepare various coating formulations, it is advantageous to provide aqueous calcium stearate dispersions with as high a solids content as possible. Such advantages include low Moisture and aggressive ions transferring into concrete harm the durability of reinforced concrete structures. To tackle this problem, damp-proofing admixtures, like calcium stearate, can be incorporated into the concrete mixture design to restrict water and aggressive ions’ ingress into concrete. Calcium stearate is a damp-proofing admixture providing a water-repellent layer along the capillary pores. As a result, it can reduce the permeability of concrete under non-hydrostatic conditions. This In a preceding paper, it was found that, during coating with solutions of a stearin salt in water, whatever the concentration used, a considerable part of the PCC surface remains free, indicating the development of an incomplete monolayer. This was explained by assuming a micelle adsorption mechanism as the dominating process in water, resulting in a multilayer structure composed of an inner incomplete chemisorbed monolayer and one or more physically adsorbed layers. This model predicted a physi What is Water-based calcium stearate?Calcium stearate lubricant is a water-insoluble metallic soap class surfactant. Generally, it is made as an aqueous liquid dispersion. Water-based calcium stearate refers to water-based calcium stearate, also known as calcium stearate emulsion and dispersion. Water-based calcium stearate is used as a white emulsion; it has an exceptionally slight smell and a slippery feel when it comes in contact with the skin. This product is mutually soluble in water, ethan The invention relates to a water-based dispersion and a preparation method, wherein the water-based dispersion takes calcium stearate as the main component and is used for papermaking. The dispersion is mainly used as an auxiliary, a functional auxiliary, and a coating lubricant in the papermaking and coating processes. The dispersion is formed by processing the calcium stearate, an emulsifier A, an emulsifier B, an auxiliary, a dispersing agent, a defoamer, a fungicide, and water; and the produ Another kind is the two-step method, and preparation calcium stearate powder is distributed to the calcium stearate powder under the effect of auxiliary agents such as surfactant in the water more uniformly earlier, grinds at last. This method is simply easy and is the maximum method of the synthetic employing of calcium stearate in the market; But, because calcium stearate has stronger hydrophobicity, the shortcoming is that the emulsifying dispersant consumption is big, and the relative cost i Calcium stearate can also be used as a flatting and waterproofing agent in coating material production. Good lubricity is widely used in paper making, applying lubricating agents and perchloroethylene heat stabilizer fields. Accompanied by the rapid development of plastics, coating, paper machine petroleum chemical industry, the demand for calcium stearate increases year by year, and market prospects are still expected. Calcium stearate has water-insoluble matter; to increase its dispersed unifo
