Water glass , also known as potassium silicate and sodium silicate, is a basic inorganic chemical raw material manufactured with soda ash, caustic soda and quartz sand as raw materials.
Common chemical parameters that make up water glass are Baume degree, silica content, sodium oxide content, modulus, density, water insoluble matter, water content. The Baume degree is used to express the concentration. But many customers will report that the same concentration, why some water glass is thicker, and some water glass is thinner, and it feels very different to use?
The thinness of water glass is chemically represented by viscosity, and the instrument for direct measurement is viscometer.
Although the instrument for measuring viscosity is viscometer, the factor that affects viscosity is indeed another parameter: modulus.
The so-called modulus is a proportional relationship between silica and sodium oxide. It has a relatively proportional relationship with viscosity, that is, under the same Baume degree, the higher the modulus, the higher the viscosity, and the lower the modulus, the lower the viscosity . For example, for the same 40 Baume water glass, the viscosity of the modulus 3.1-3.4 will be higher than that of the modulus 2.1-2.5.
So everyone should be clear that the same concentration is not the same effect. It is best to choose the water glass that suits you.
