Development of Sodium Silicate Adhesives for Electrical Steel Bonding
Inorganic adhesives have several benefits over traditional joining methods for joining electrical steels used in magnetic cores of numerous industrial applications. As insulators with very high melting temperatures, the adhesives offer the possibility of increasing the efficiency of these machines. The aim of this project was to characterize sodium silicates as adhesives for such applications a...
متن کاملSilicate-Promoted Phosphorylation of Glycerol in Non-Aqueous Solvents: A Prebiotically Plausible Route to Organophosphates
Phosphorylation reactions of glycerol were studied using different inorganic phosphates such as sodium phosphate, trimetaphosphate (a condensed phosphate), and struvite. The reactions were carried out in two non-aqueous solvents: formamide and a eutectic solvent consisting of choline-chloride and glycerol in a ratio of 1:2.5. The glycerol reacted in formamide and in the eutectic solvent with ph...
متن کاملCow blood adhesive: Characterization of physicochemical and adhesion properties
strength were measured. The degree of hydrolysis increased with increasing basic pH value. The adhesive exhibited shear-thinning viscous behavior. Both viscosity and shear-thinning character showed a remarkable shift at pH 10.2 and at 50 1C. The curing time decreased with curing temperature within 60–80 1C range. The water solubility of the adhesive was the lowest when sodium silicate, the curi...
متن کاملSynthesis and characterization of inorganic , lamellar nanofillers with high aspect ratio
9 Mesostructured silica phases with lamellar structure were prepared by the liquid crystal templating (LCT) technique, from double chain alkylammonium surfactant and sodium silicate or tetraethylorthosilicate (TEOS) silica precursors. The structural characterization of these phases is presented and compared. Surface modification of the silica layers, together with elimination of the organic tem...
متن کاملBonding-Compatible Corrosion Inhibitor for Rinsing Metals
A corrosion-inhibiting mixture of compounds has been developed for addition to the water used to rinse metal parts that have been cleaned with aqueous solutions in preparation for adhesive bonding of the metals to rubber and rubberlike materials. Prior to the development of this corrosion inhibitor, the parts (made, variously, of D6AC steel and 7075-T73 aluminum) were rinsed by deionized water,...
