Six bonding methods of refractory adhesive
- Hydration combined - agent reacts with
water hydration hydration products generated at room temperature by means of a
combination combined.
- Chemical binding - binding means between
the agent and curing agent, binding agent and the refractory, or chemical reaction
at room temperature or with heating to produce a chemical reaction which
generates a compound having a binding agent binding effect.
- Polymeric binding - by means of a
catalyst or a cross linking agent, the bonding agent is a poly condensation to form
a network-like structure to produce bonding strength.
- Ceramic bond - means combining
low-temperature sintering, which can be added in bulk refractory to reduce the
sintering temperature refractory additives or metal powders, in order to
greatly reduce the temperature of the liquid appeared to promote the
solid-liquid reaction at low temperatures combine to produce low-temperature
sintering.
- Cohere - rely on adding coagulant to make particles (colloidal particles) combine to produce condensation occurs
- Adhesive binding - is one of the following means of several physical effects
arising from combining.
- Physical adsorption: intermolecular interactions
depend - van der Waals force binding generated;
- Diffusion: the role of the
thermal motion of molecules of the substance, the molecules are bonded with the
adhesive composition of the diffusion interaction occurs forming a diffusion
layer, thereby forming a strong bond;
- Electrostatic interactions: the
interface is bonded with the adhesive composition of the existence of the
electric double layer by electrostatic forces arising from the electric double
layer combination.
