Chemical Hardener Making Machine

Chemical hardeners are used to make concrete surfaces denser and harder. They are usually made of inorganic materials and come in dry or liquid forms that can be used on concrete surfaces.There are many types of hardeners, but the most important ones are classified into aliphatic and aromatic amines, anhydrides, and polyamides. Usually, hardener molecules are much smaller than resin molecules and therefore, have low viscosities.The active ingredients of liquid surface hardeners are Lithium Silicate, Sodium Silicate and Potassium Silicate. The basic principle of operation of these products is as follows: Lithium silicate, sodium silicate and potassium silicate react with calcium hydroxide in concrete and form calcium silicate.
