The density of stearic acid used in this study is g/cm 3, the BET of the raw slag is m 2 /g and the content of SA is 1%. Therefore, using the above formula, the theoretical thickness of the stearic acid coating is derived, yielding nm.
This system is most commonly used for coating calcium carbonate with stearic acid to meet the requirements for fillers used in the plastics industry. The EPIC's proprietary injector design achieves a high degree of atomization of the coating fluid, while the high tip speeds produced by the counterrotating pin disks provide the high shear ...
A series of experimental precipitated calcium carbonates coated with commercial stearic acid (stearin), with the coating amount of stearin added to the PCC particles ranging from 3 to wt %, were prepared in aqueous medium and characterized by Fourier transform infrared spectroscopy, thermogravimetric analysis, and differential scanning calorimetry. A series of experimental precipitated ...

Stearic acid is widely used to coat basic fillers such as calcium carbonate, magnesium hydroxide [14, 18,2122 23 and hydromagnesite [24]. Compounds containing stearate coated fillers show ...
The optimum level of surface coating was found to correspond to the minimum of surface tension [13], [14], [15], which is reached at complete monolayer coverage, or rather, when all active sites on the surface of calcium carbonate react with stearic acid molecules. Surface coating of PCC with stearic acid considerably reduces its surface ...

Since the particle size, shape, specific surface area, and purity of the ground calcium carbonate (GCC) decide its usability in the paper, paint, and plastic industries, the effect of grinding is important. However, the effect of stirred and ball mill grinding on the particle shape of GCC by dynamic image analysis (DIA) is still lacking in the literature. Therefore, the aim of this study is to ...
The coating of the lime mud flocs with newly formed PCC via the in situ calcium carbonate process (LHCC50, LHCC70, pLHCC50, and pLHCC70 in Figure 5) increased the lightness further. We then compared the role of the in situ calcium carbonate process to the simple mixing of the LMHTG and commercial PCC (LMHTG/PCC50 and LMHTG/PCC70 in Figure 5 ...
This research focuses on recycling rubber tire waste through pyrolysis to produce recovered carbon black (rCB). The rCB is combined with recycled lowdensity polyethylene (rLDPE), calcium carbonate (CaCO 3 ), fatty acid, metallic stearate, and polyethylene (PE) wax to create an rCB masterbatch for household packaging. Surface modification of CaCO 3 particles using stearic acid improves the ...
Surface modification of precipitated calcium carbonate particles (calcite) in a planetary ball mill using stearic acid as a modification agent for making dispersion in hydrocarbon oil was investigated.
A planetary ball mill, PM 100, with tungsten carbide balls of diameter mm was used. The vial containing 62 g of powder and 620 g of tungsten carbide balls in the ratio 1:10 (wt/wt) was utilized.
Stearic acid is a common longcarbon chain saturated fatty acid. It has both the lipophilic end of the long carbon chain and the hydrophilic end of the carboxyl group. The surface of nano calcium carbonate is hydrophilic, so stearic acid is coated on the nano, the surface of calcium carbonate can greatly improve its lipophilicity. When it is filled in rubber, plastics, advanced inks, its large ...
