Effect of ZrO2 content on the properties of diamond grinding wheel vitrified bond

Study of Monitoring the Real Liquid Level of the SBR Discharge System Accurately Based on Soft-sensing

“…The mainstream production technology of SBR at present is the low temperature emulsion copolymerization with butadiene and styrene as the main raw material, dicumyl peroxide as the initiator, formaldehyde sodium bisulfate and EDTA ferric sodium salt as the activator, mixed soap of potassium salt of disproportionate rosin and sodium salt of fatty acid as the emulsifier, water as dispersion medium. [5,6,9] Together with other unit operations, such as monomer recycle, latex blending (or oil filling), salt-free condensation and after-treatment, the massive SBR is produced [7] . SBR production process is shown in Fig.1 …”

Characterization of low sintering temperature and high strength SiO2-B2O3-CaO vitrified bonds for diamond abrasive tools

“…Previous studies have investigated the influences of different additives (Bi 2 O 3 , CaO, ZnO, TiO 2 , alkali oxides, ZrO 2 , polycrystalline mullite fibers, etc.) and their effects on the mechanical properties and microstructures of vitrified bond super-hard abrasive tools [12][13][14][15][16][17][18]. Research has shown that borosilicate vitrified bonds with low refractoriness, low expansion coefficients, high bending strength, and good wetting performance have potential use with diamond abrasive tools; however, some problems remain, such as increasing the vitrified bonds strength while decreasing the sintering temperature.…”
