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. Although treated sodium silicate samples are composed of the same elements in similar proportions, as the untreated sodium silicate samples, the water solubility of the treated and untreated substances is very different.

Abstract:
A method of forming a thin film strip. The method comprises coating a liner substrate with a wet slurry of film forming ingredients and drying the wet slurry in a drying oven to form a film. A moisture content of the film is measured as the film exits the drying oven and the film is rewound on itself. The rewound film is then stored in a minimal moisture loss environment during a curing process.
Abstract:
There is disclosed a method for permanently and decoratively enhancing a polyethylene surface of a preformed article. In this method, a decorative enhancement composition is created by blending particulate thermoplastic powder, a binder solid, and a colorant into a liquid carrier. The particulate thermoplastic powder bonds to the colorant, the binder solid promotes adhesion of the colored thermoplastic to the polyethylene surface until it can be bonded, and the liquid carrier facilitates the transfer of the colored thermoplastic to the polyethylene surface of the preformed article. The decorative enhancement composition is applied to the polyethylene surface. The deposited decorative enhancement composition and the interfacing polyethylene surface are heated sufficiently to incorporate the decorative enhancement composition into the polyethylene surface. The enhanced polyethylene surface is allowed to cure by removal of the application of heat. Upon curing, the decorative enhancement composition is permanently incorporated into the polyethylene surface enhancing the physical properties and the appearance of the preformed article. This invention also comprises a decorative enhancement composition for the permanent decorative enhancement of polyethylene surfaces of preformed articles consisting essentially of a dry weight ratio of 30 to 70 percent binder solid to 70 to 30 percent particulate thermoplastic powder combined with colorant, wherein colorant comprises 9 to 50 percent of the total dry weight of the binder, powder, and pigment, mixed with liquid carrier, wherein the liquid carrier comprises 20 to 90 weight percent of the overall decorative enhancement composition.

Abstract:
The present invention provides a method for preparing mesoporous TiO2 thin films with high antibacterial and photocatalytic activities. The method involves coating onto a substrate a TiO2 sol-gel prepared from hydrolysis and condensation of titanium alkoxide in the presence of a stabilizer and thermally treating the substrate at a temperature ranging from 400° C. to 900° C. The TiO2 thin films fabricated according to the method of the present invention show two times higher antibacterial and photocatalytic activities than the conventional TiO2 thin films.

Abstract:
A C/Si/O composite material having improved oxidation resistance is prepared by impregnating graphite with a crosslinkable silane or siloxane, causing the silane or siloxane to crosslink within the graphite, and heating at 300-1,200° C. in a non-oxidizing gas. The C/Si/O composite material can be efficiently prepared through simple steps, on an industrial scale and at a low cost and will find use as a high-temperature structural material by virtue of oxidation resistance.
