Sodium Bisulfate Technical Grade Chemical Grout Acidifies a grout formulation to form a temporary seal while constructing underground tunnels. SBS is combined with aluminum sulfate, magnesium sulfate, and other fillers as a dry compound. This compound is then put in a water solution and combined with liquid sodium silicate for spraying on tunnel walls. The more SBS added, the faster the gel time of the grout formulation. Cleaning Compounds SBS is the acidifier and cleaning ingredient in many compounds. Because of its consistent particle size, SBS is compatible with most formulas. It has been used in formula for cleaning cement, railroad cars, brass, lavatories, showers, and metals. Contract packers producing their own brand name products and those repackaging for major Companies are candidates for SBS. Concrete Wash Out Reduces alkalinity in "wash out" ponds formed by concrete truck clean out. Area concrete companies are potential distributor customers. Jones-Hamilton Co. [echniwl service representatives can recommend pH adjustments. Dry Toilet Bowl Cleaners SBS is [he mayor component In most dry bowl cleaner formulations. Atypical U.S. formulation Consists of 64-70% SBS by weigh[ with salt, soda ash, surfactant and a dye. These cleaners are very popular for hard water areas that generate iron deposits. The dry bowl cleaners are also approved as disinfectants. Emulsion Breaker SBS is used [o separate synthetic and petroleum-based organic compounds from water solutions. Spent metalworking Fluids are pumped into a 55-gallon plastic drum. SBS Is adtled at a rate of 10-15 lbs. and agitated. Wait 24-72 hours until all the oils and organics form a surface layer separated from the water layer. Skim the surface layer and Dlace this residue in a discharge container. Adjust the pH of the water with sodium hydroxide to 7 before discharge. Foliar Fertilizers Adjusts pH of foliar fertilizers for cotton. These liquid fertilizer blends are applied after mid-growth of the cotton plant. Most have a pH range of 8.0- 8.5. If not reduced to a pH of 6.5, the plan[ will take up the fertilizer too fast resulting in plant burn and less fruit growth. SBS is applied at 25-30 lbs. per 16,000-gallon batch to adjust [he pH. Leather Tanning SBS acts as [he acidifier in leather compounds when used in combination with quebacho tannin. 565 is combined with fillers and other chemicals [o acidify hides used for shoe sole leather. Metal Finishing SBS is [he major component in dry acid bath Formulations for metal cleaning. The general formula for most acidic baths include: salts of fluorides (5-lOMo), SBS (90-95%) plus a surfactant. The concentration is generally 4 oz. to 3 lbs. per gallon of water, At temperatures up to 170?F, this bath will clean steel, copper, brass, zinc, aluminum, nickel, magnesium, titanium and stainless steel. Typical U5e5 are for pickling, Scale removal, rust removal and etching. Pulp and Paper 565 acidifies slurries of "broke' paper [o remove cumin and melamine resins before paper making. At specialty paper mills, scrap paper is accumulated and recausticized. The excess resins have to be removed before reprocessing. SBS is added at 10 lbs. per [on of paper slurry before re-routing onto [he paper wire. Recycled Cellulose Insulation 565 reacts with alkaline chemicals in recycled paper to prevent ammonia gas release. Blown insulation i5 produced from recycled newspaper. Ammonium sulfate and boric acid are added as a fire retardant. Alkaline chemicals used in paper manufacturing are present in the recycled newspaper. if not treated Page 2 of 3 http://www.jones-hamil[on.com/sections/products/sbst~apps.html 11!17/04
