Sample records for industrial inorganic pigments

Nuclear magnetic resonance has been used to look at a number of colourful industrial inorganic pigment systems, most of which are sold commercially in large quantities. Industrial inorganic pigments were examined using 19 F, 23 Na, 29 Si, 51 V and 91 Zr NMR. In these systems, paramagnetic species are incorporated into the sample in small quantities creating the colourful industrial inorganic pigment.

The impurity dopants in the systems studied either dope directly into lattice sites in the zircon, or form an extra chemical phase. NMR was able to distinguish between these two doping mechanisms in a number of industrial inorganic pigments. Most spectra showed effects which were due to the magnetic influence of paramagnetic colouring species, and the strength of the interaction depended on the magnetic moment of the ion containing the unpaired electron. In the case of vanadium doped zircon, the moment was small enough that it allowed extra contact shifted peaks to be resolved in the spectra which indicated that the V 4+ colouring ion probably substitutes into both the tetrahedral SiO 4 site, and at the dodecahedral ZrO 8 site. This is of current interest, and many other spectroscopic and computational experiments have also been performed to elucidate which of the two sites V 4+ is located at.

A 17 O-enriched zircon sample was also synthesised through a sol-gel route, and the local environment at the oxygen sites was followed through zircon formation from the TEOS and Zr-isopropoxide precursors. A multinuclear approach looking at the 11 B, 23 Na, 27 Al and 29 Si isotopes within silver containing glasses was able to provide information about the coordination of the isotopes within the glasses. 109 Ag NMR was evaluated as an experimental technique for examining silver containing compounds. 119 Sn NMR was used to quantify the amount of Sn(ll) and Sn(IV) in orange coloured SnO-ZnO-TiO 2 (TZT) produced pigments, and the colour of the sample was found to correlate with the width of the Sn(IV) peak.

Industrial Enamel Paints, Equipment and Supplies

Industrial enamel paint, paint equipment, and paint supplies are used to apply paints, coatings, and stains to surfaces and equipment to protect them and refresh their appearance.

Interior paints and stains are suitable for furniture, floors, walls, ceilings, and other indoor surfaces. Exterior paints and stains are designed for buildings, houses, decks, patios, driveways, fences, and other outdoor surfaces. Brushes, rollers, sprayers, trays, drop cloths, and other painting supplies let painters apply paints, stains, and coatings neatly and efficiently.

Industrial enamel paint and wallpaper tools prepare surfaces for painting and wallpapering, streamline the application of paint and wallpaper, and facilitate cleanup when the job is done. Floor coatings protect floor surfaces from traffic, abrasion, moisture, cleaning chemicals, and other damaging elements. They can also improve the floors’ appearance or add increased traction in pedestrian areas such as walkways, stairs, and ramps.
