Sodium metasilicate is a member of the sodium compound family, according to the International Programme on Chemical Safety 1 2. A very basic compound, sodium metasilicate is used in a variety of industrial and household settings 2. While it is a cleaning and de-rusting solution, it is highly corrosive and should be handled with care.
Dec 04, 2009 · I have used a sodium metasilicate-based cleaner for 7 years. My container is nearly empty. It has worked effectively on ceramic tile, cement-based tiles, vinyl and aluminum siding and removes stains from carpet textiles, including nylon, polyester and acrylic, quite thoroughly. I first used it to remove salt and road dirt from my car's floor mats.

In construction of the block traffic curb, the Contractor shall have the option of using either length block shown in the plans, provided the same length block is used throughout the entire project. The curb units shall be made from portland cement and high quality sand and gravel, the
Aug 01, 2015 · The tetrasodium pyrophosphate has a slightly higher pH and will initiate a light attack on the base aluminum itself. Most other builders have a higher pH and require the use of sodium metasilicate to inhibit the attack of the base aluminum.
The use of sodium silicate as a wood preservative may not be common, but it was hardly dreamed up in 2005. I am in the process of using an old method at home that uses sodium silicate solution as a wood sealer/fireproofing which is then sprayed with a boric acid solution which keeps the bugs at bay and forces the sodium silicate to gel.
A cleaning method for removing scales, etc., deposited on the interior of a polymerization reactor which has been used in emulsion or suspension polymerization. This method uses a chemical cleanser comprising a soap builder an, alkali agent, an aqueous solution or dispersion of a surfactant, and an organic solvent and/or polymerizable monomer.
Two anionic surfactants were used in this study. AOT was dissolved into the oil phase, while sodium oleate was used by dissolving it into the water phase. For each surfactant, several concentration conditions within 0.05 - 1.0 wt.% were tested, and the breakthrough
