Sodium silicate may be used for various paints and coatings, such as those used on welding rods. Such coatings can be cured in two ways. One method is to heat a thin layer of sodium silicate into a gel and then into a hard film. To make the coating water-resistant, high temperatures of 100 °C (212 °F; 373 K) are needed. [16]
Salts used may include metasilicates, alkali metal hydroxides, sodium carbonate etc. [3] Enzymes: Break up protein-based food deposits, and possibly oil, lipid and fat deposits. [4] The enzymes used are similar to the ones used in laundry. [5] Anti-corrosion agent(s): Often sodium silicate, this prevents corrosion of dishwasher components.
An aqueous solution of sodium silicate is acidified to produce a gelatinous precipitate that is washed, then dehydrated to produce colorless silica gel. [6] When a visible indication of the moisture content of the silica gel is required, ammonium tetrachlorocobaltate(II) (NH 4 ) 2 [CoCl 4 ] or cobalt(II) chloride CoCl 2 is added. [ 6 ]
The same principle applies when baking soda is used to boil pretzels before baking. The pantry staple can also serve as a tenderizer for certain ingredients—like meat and even canned chickpeas .
Sodium alginate produces a medium viscosity gel but may have some aftertaste. High-methoxy pectin is one of the most widely used gelling agents in food processing. It reacts with some sugars and acids and sometimes includes minerals to improve gelling process. Low-methoxy pectin reacts with calcium, and is used for the preparation of low sugar ...
Sodium Metasilicate reacts with acids to produce silica gel. [6] Cements and Binders - dehydrated sodium metasilicate forms cement or binding agent. Pulp and Par - sizing agent and buffer/stabilizing agent when mixed with hydrogen peroxide. Soaps and Detergents - as an emulsifying and suspension agent.
Let’s chat baking soda. Chances are you probably have a box chilling in the back of your fridge. But the white stuff, otherwise known as sodium bicarbonate, can do so much more than just absorb ...
Typical molecular sieves are of the LTA type. They feature sodium aluminosilicates cages (sodium not shown) that have high affinity for water. Vials of mesoporous silica. A molecular sieve is a material with pores (voids or holes), having uniform size comparable to that of individual molecules, linking the interior of the solid to its exterior.
