The principles of refractory binder

(1) Combination of hydration: by means of the binder at room temperature with the water hydration reaction of hydration products generated by the combination. Such as various types of cement are combined through the combination of mechanisms to achieve and make the material strength.

(2) Chemical combination: with the combination of agents and coagulants, or between the binder and refractory at room temperature chemical reaction occurs, or when heated to produce a chemical reaction with a combination of compounds generated by binding. Such as sodium silicate (sodium silicate) binding agent plus sodium silicate coagulant.

(3) Poly-condensation combination: by means of the catalyst or cross linking agent, the binder occurs poly-condensation to form a network structure to produce bonding strength.

(4) Sintering combination: in the refractory material can reduce the sintering temperature of additives or metal powder, in order to greatly reduce the temperature of the liquid phase, and promote solid-liquid reaction at low temperature to produce low-temperature sintering combined.

(5) Adhesion (adhesion): by means of the following physical effects of one or more of the role of superposition to produce a combination of: one adsorption; the other is the diffusion effect; the third is the electrostatic effect.

(6) Agglomeration: By adding it, the particles (colloidal particles) are agglomerated to form a bond.
