Analysis of silica and silicon carbide abrasives characteristics on denim wear

Abstract

This paper presents the development of certain abrasives based on selected industrial wastes and gives an idea of their postuse behavior. These abrasives are manufactured using two methods: pulverization and coating. For these purposes, we used cellulosic nonwoven fibers as reinforcement, three types of resin (polyurethane, acrylic, and polyester) as a matrix, and abrasive grains of silicon carbide (SiC) and silica to obtain the abrasive character. We report the wear of the developed materials by abrasion, the evaluation of their roughness, the influence of the type of the abrasive grains, and their sizes on the wear performances. Scanning electron microscopy was performed to show the morphology of abrasives. The weight loss of abrasives was measured by thermogravimetric analysis and its derivative. Fourier-transform infrared spectroscopy allows the chemical characterization and identification of abrasive grains. Under the same test conditions, experimental results indicate that silica-based abrasives exhibit higher surface roughness and abrasion wear rate than SiC-based abrasives.

Granularity reconstruction and characterization of silicon carbide micronized powders

“…For ceramic MSIM-2022 Journal of Physics: Conference Series 2499 (2023) 012019 IOP Publishing doi:10.1088/1742-6596/2499/1/012019 2 materials, smaller SiC particles are helpful for densification and improving their strength and performance [10] . Elaissi et al [11] research shows that the abrasive wear of SiC composite materials is mainly determined by particle size and type, and particle size is the most influential factor in the wear state.…”

Preparation of apricot kernel shell powder added polyester/calcium carbonate composite discs and investigation of their abrasive properties

“…Abrasive discs can be prepared from natural or synthetic materials, and they are usually prepared by attaching hard and abrasive materials to a binding matrix material. They are frequently produced from materials such as SiC, BC, BN, CeO, zirconia, aluminum oxide, iron oxide, silica and corundum [17][18][19][20][21][22]. However, today, studies on the preparation of abrasive discs from more sustainable, Apricot kernel shell is suitable filler for abrasive materials with its strong, hard structure and dense cellulose content.…”
