Chitosan is a natural polymer that can be used as source of materials because it has good characteristics. in the cosmetic sector humectant, thickener, moisturizer, antioxidant, sunscreen cream, and stabilizer. The shell chitosan shells an emulsion stabilizer Hand Body Cream product problems its unstable nature so oil water are easily separated. parameters observed were stability, pH, TPC. resu...

Greased bearings in electric motors (EMs) are subject to a wide range of operational requirements and corresponding micro-environments. Consequently, greases must function effectively these conditions. Here, the tribological performance four market-available EM was characterized by measuring friction wear silicon nitride sliding on hardened 52100 steel. The evaluated had similar viscosity grade...

in this research work, the parameters affecting the settling velocity within the thickeners were studied by introducing an equivalent shape factor. several thickener feed samples of different densities including copper, lead and zinc, and coal were prepared. the settling tests were performed on the samples, and the corresponding settling curves were plotted. using the linear regression analysis...

Dewatering of water-coal slurry or thickened product under conditions operating SUEK-Kuzbass JSC enrichment plants is a promising direction obtaining technogenic mineral resources. It should also be noted that the quality obtained will directly influenced by initial raw materials. If content carbon particles high and average ash solid phase low, such interest in terms additional volumes coal af...
