Abstract:
The present disclosure relates generally to deicer compositions comprising a liquid deicing agent which is as an aqueous solution of a deicing salt and additives that provide reduced corrosiveness with reduced biochemical oxygen demand. Aspects of the disclosure are particularly directed to use of the deicer composition as a liquid deicer or an anti-icer. The deicer composition can further include a solid deicing agent such as sodium chloride, where the liquid deicing agent and additive form a pre-wetting agent when mixed with the solid deicing agent to form a pre-wetted deicer.
Abstract:
In some variations, the invention provides a deicer composition comprising alkali acetate, a solvent (such as water) for the alkali acetate, and a corrosion inhibitor comprising lignin or a lignin derivative. The acetate and the lignin or lignin derivative are preferably each derived from the same biomass feedstock. In some embodiments, the alkali is selected from the group consisting of potassium, sodium, magnesium, calcium, and combinations thereof. In some embodiments, the alkali acetate is present in a concentration from about 30 wt % to about 99 wt %. Deicer products may be a crystallized or dried form of the deicer composition.
Abstract:
A natural antibacterial waterproof composition for soil and wood and a method for manufacturing includes beef tallow, soybean oil, turpentine, pine resin, paraffin, and a natural antibacterial insecticide, wherein the natural antibacterial insecticide is made by extracting effective components from ginkgo leaves through hot-water extraction. According to the present invention, the natural antibacterial waterproof composition for soil and wood is applied to the surfaces of the soil wall, soil brick and wood and absorbed therein, thus providing waterproofing performance and protecting the soil wall, soil brick and wood from harmful insects like ants, worms and so on. Further, the composition has excellent waterproofing and insecticidal performance during a long period of time as well as during a short period of time, thus desirably decreasing the maintenance cost.
Abstract:
The invention relates generally to a mixing system for mixing a dry material with a liquid. The mixing system includes a supply of dry material and a supply of liquid. An infinitely variable metering device meters the dry material into the liquid. A sensor senses the ratio of dry material to liquid. The sensor is operatively connected to the metering device to control the metering device to obtain a desired ratio of dry material to liquid. The dry material is dispensed volumetrically by volume of liquid to form the desired ratio of dry material to liquid.
