  • Publication number: 20140261047
    Abstract: A dimensionally stable combination of wood and inorganic material is provided as railway sleepers or ties. The wood is preferably a softwood impregnated with an alkali-metal or alkaline earth-metal silicate solution, which has been rendered water insoluble after impregnation. Preferably sodium silicate (water glass) is used as the solution. Any cracks, gaps, shakes, splits, or the like, remaining after impregnation are filled so as to deny entry of water, ice, snow, and debris into such cracks, etc. Predrilled holes in the ties receive deeply threaded railway spikes, capped by a hexagonal cap to hold the rails. Preferably, the spikes and caps are coated with a similar solution to provide both corrosion protection and strong bonding of the components.

  • Patent number: 8221893
    Abstract: Wood products, specifically wood commonly used in construction including dimension lumber, pressure treated pine, composite wood materials such as plywood, particle board, and wafer board, and samples of paper and fabric were variously treated with concentrations of sodium silicate (Na2O.SiO2) also known as water glass. Cellulosic materials including dimension lumber, plywood, particle board, wafer board, paper, and fabric were treated with sodium silicate (Na2O.SiO2) in concentrations ranging from 400-0.04 g Na2O.SiO2/kg water. To overcome the disadvantages of sodium silicate, sodium silicate treated samples were further treated to convert the water soluble sodium silicate to a water insoluble form, thereby overcoming the disadvantages of water solubility and rendering the material effective for internal and external uses.

  • Patent number: 7297411
    Abstract: Wood products, specifically wood commonly used in construction including dimension lumber, pressure treated pine, composite wood materials such as plywood, particle board, and wafer board, and samples of paper and fabric were variously treated with concentrations of sodium silicate (Na2OSiO2) also known as water glass. Cellulosic materials including dimension lumber, plywood, particle board, wafer board, paper, and fabric were treated with sodium silicate (Na2O.SiO2) in concentrations ranging from 400-0.04 g Na2O.SiO2/kg water. To overcome the disadvantages of sodium silicate, sodium silicate treated samples were further treated to convert the water soluble sodium silicate to a water insoluble form, thereby overcoming the disadvantages of water solubility. and rendering the material effective for internal and external uses.

  • Patent number: 6040057
    Abstract: Materials variously treated with sodium silicate were studied until enough information was obtained to find a way to solve the problems that have prevented sodium silicate from being the used as a fire retardant. These problems are: 1) water solubility (miscible with water), which results in extensive leaching when exposed to water, 2) cracking, chipping and peeling of treated surfaces, and 3) surface granulation. During flame tests it was discovered that sodium silicate formed a foam-like material, and this material was found to have become water insoluble, yet its elemental composition had remained virtually identical to that of the unmodified sodium silicate. This investigator proposes that under the influence of heat and dehydration, sodium silicate undergoes a polymerization process resulting in particles sizes too large to dissolve in water, and then developed a mechanism to explain how the process could occur.
