3these active substances, but they are with the existence of " vitreum " inert condition, by the chemical process exciting, allow it that chemical reaction occurs, produce cohesiveness, can greatly reduce inorganic gel consumption and improve its utilization ratio, and can accelerate inorganic gel setting rate, improve its early strength.Active activator is preferably one or both in calcium chloride, sodium-chlor (Industrial Salt).
The molecular energy oriented adsorption of water reducer is in cement particle surface, make inorganic gel particle surface with same electric charge, form electrostatic repulsion, impel inorganic gel particle mutually to disperse, flucculation structure is destroyed, discharge and be wrapped part water, participate in flowing, thereby effectively increase the mobility of high strength sound binding agent, it is good that the slump of binding agent slurry keeps, reach the effect of diminishing, and then improved the intensity of tack coat.Because the hydrophilic group polarity in water reducer is very strong, therefore the water reducer adsorption film of inorganic gel particle surface can form the stable solvation moisture film of one deck with water molecules, this layer of moisture film has good lubrication, can effectively reduce the intergranular sliding resistance of inorganic gel, thereby the mobility of high strength sound binding material slurry is further improved.Water reducer can be at adsorbed inorganic gel particle surface, is formed with the three-dimensional adsorption layer of certain thickness wetting ability.When inorganic gel particle near time, adsorption layer starts overlapping, between inorganic gel particle, produces sterically hindered effect, overlapping more, sterically hindered repulsion is larger, also larger to the obstruction of inorganic gel interparticle coagulation effect, makes the slump of high strength sound binding material slurry keep good.Water reducer is preferably one or more in calcium lignin sulphonate, sodium lignosulfonate, naphthalene series high-efficiency water-reducing agent.
Hydrophobic powder can strengthen intensity and the water resistance of system.Hydrophobic powder is preferably the organic silicon water-proofing powder that Chengdu clear spring waterproofing agent of organosilicon factory produces.
Dispersion agent can have the interfacial agent of lipophilicity and two kinds of opposite nature of wetting ability in molecule simultaneously.Dispersion agent can impel each component of high strength sound binding agent to be uniformly distributed at slurry, and prevents solid particles sediment and the cohesion in slurry.Dispersion agent is preferably Sodium hexametaphosphate 99.
The sound insulation principle of sound insulation binding material: formed sound insulation binding material by inorganic gel, stopping composition, sound absorbent material, cracking resistance fortifying fibre and various auxiliary agent, added suitable quantity of water mix even, obtained sound insulation binding paste.Wherein cracking resistance fortifying fibre is woven into one " net " in system, the skeleton of constitution system, stopping composition and sound absorbent material are filled in equably in " net " under the effect of dispersion agent, inorganic gel is bonded together cracking resistance fortifying fibre and stopping composition, sound absorbent material securely, and can form small sealing microbubble in system.Sound wave is in communication process, and easy endergonic sound absorbent material and cracking resistance fortifying fibre have consumed the energy of sound wave; The minimum gas blocking in the microbubble of sealing, almost approaches vacuum, also the transmission of acoustic wave segment capable of blocking.The moisture that the auxiliary agent such as water reducer, hydrophobic powder can be controlled well in system effectively, has reduced the amount of water medium, acoustic wave propagation velocity is slowed down, thereby increased the power consumption time of other approach.Number of ways comprehensive, makes sound insulation binding material have good sound-proofing properties.
