Solidification agent

The compatibility of typical metal waste components with solidification agents is discussed by Wiedemann (1982), Wiles (1987)... 

For solidification of epoxy oligomers, numerous substances are produced, such as aliphatic polyamines, aromatic amines, dicyanoamines and their derivatives, the anhydrides of di- and polycarboxylic acids, as well as a number of catalysts for solidification. These substances impart a large variety of technological properties to epoxy oligomers. Some properties of the main solidification agents produced worldwide are listed in Table 8 [229-231].

Solidification may involve chemical reaction of the waste with the solidification agent, mechanical isolation in a protective binding matrix, or a eombination of chemical and physical processes. It can be accomplished by evaporation of water from aqueous wastes or sludges, sorption onto solid material, reaction with cement, reaction with silicates, encapsulation, or embedding in polymers or thermoplastic materials. 

In RPs, insufficient compaction and consolidation before plastic solidification or cure will result in air pockets, incomplete wet-out and encapsulation of the fibers, and/or insufficient fiber or uniform fiber content. These deficiencies lead to loss of strength and stiffness and susceptibility to deterioration by water and aggressive agents. 

STABL Stabilization Stabilization (also referred to as solidification) involves the addition of stabilizing agents (e.g., Portland cement) to a waste to reduce the teachability of metal constituents... 

The production of CLS by the melt dispersion technique is based on the melting of the lipid core material together with the lipophilic agent (i.e., phospholipids). Afterward, a warm aqueous solution is added to the molten material and is mixed by various methods (i.e., mechanical stirring, shaking, sonication, homogenization). Then the preparation is rapidly cooled until lipid solidification and the formation of particle dispersion. This method was used by Olbrich et al. [19] to produce the cationic solid lipid nanoparticles to use as novel transfection agent.

Furthermore, it was cleared that the adhesion force of the remained clusters to the agent and the acceleration ability of the agent for heterogeneous nucleation were closely related each other on the acceleration mechanism for the solidification of CaCl2 6H20 melt.

The soil-cement mixing wall (SMW) is an in situ technology for the fixation, stabilization, and solidification of soils contaminated with metals and semivolatile organic compounds. SMW can be used to treat soils contaminated with pesticides, polychlorinated biphenyls (PCBs), phenols, and poly aromatic hydrocarbons (PAHs) to depths of up to 100 ft. The technology uses hollow-stem augers to inject solidification/stabilization agents and blend them with the soil. 

The second study (Ref 58), published in 1976, likewise noted a 10—11% shrinkage upon solidification, and studied the solubility of various gases in the melt, as well as the rate of solidification of the supercooled liq at various rates of heat removal and at various temps. The role of nucleating agents was discussed, and HNS was shown to be effective. The established physical principles of solidification were found fully applicable t TNT...
