Another approach to providing sufficient borate
to a bridge timber is to drill holes in the member before treatment and fill the holes with solid or powdered preservative.
could not precipitate from sea water under dynamic, crystallizing conditions until the concentration was 2500-4000 ppm B because of extreme super saturation .
The Gerstley borate
mine is located near the town of Shoshone, California, population 52, near the Nevada state line, approximately 50 miles east of Death Valley.
The general purpose of this project is to develop decay-resistant glulam and LVL using combined borate
treatment and effective transparent coating systems.
pressure treatment, the precut logs are enclosed in a pressure-treating cylinder, where a vacuum is applied.
Roskill says that smaller end-uses of boron compounds with potential for future growth include flame retardants, in which borates
are used in place of, or in addition to, antimony trioxide, and in neodymium-iron-boron magnets, which are used in applications where high ratios of magnetic strength to weight are required.
Insoluble impurities, including anhydrite, magnesite, hematite, borate
minerals and clays, can sometimes make up as much as 50% of the rock, but are typically present at a much lower concentration.
In this study, short lengths of heavily blue stained, post-MPB lodgepole pine lumber (Pinus contorta) were treated with the buffered amine oxide carrier to borate
levels less than the retentions recommended for protection against attack by the Formosan subterranean termite (average, 0.
Borax supplies 45 percent of the global demand for borates
- a salt used in products ranging from detergents, shampoos and water softeners to food preservatives, ceramics and fiberglass.
are added to the liquor cycle to expel carbon dioxide from sodium carbonate, forming trisodium borate
in the recovery boiler smelt.
Two men were instrumental the initial development of the raw borates
from Death Valley and the Mojave Desert for eventual worldwide benefit.
were discovered in Death Valley in 1873, only a couple of years after the discovery of the Nevada playa borates
at Columbus Marsh and Teel's Marsh.
