a) Silicates are stronger alkalis since their (Si O 2 / Na 2 O) ratio is low. For sodium silicates, this ratio can be changed by optionally adding sodium hydroxide. The pH value of silicate solutions is relatively high. For example, 2O metasilicate pH for 5H is 30 grams / liter solution 12.8. This alkalinity has the same advantages over organic soils as sodium carbonate.
Silicates are used in a wide variety of industries. The use of silicates in detergents is the most common use. Washing and cleaning products Large quantities of liquid silicates have been successfully used in the formulation of washing and cleaning products for many years. In this area, manufacturers can benefit from many features of these raw materials. Silicates act as a buffer, source of alkali and binders for the neutralization of metals responsible for water hardness. Same...
