Technology reclaiming

Reclaiming is a procedure in which the scrap tire rubber or vulcanized rubber waste is converted, using mechanical and thermal energy and chemicals, into a state in which it can be mixed, processed, and vulcanized again. The principle of the process is devulcanization. In devulcanization, it is assumed that the cleavage of intermolecular bonds of the chemical network, such as carbon-sulfur and/or 

A mechanical or reclaimator process (LaGrone, 1986 Szilard, 1973 Klingensmith, 1991 Leyden 1991) has been used for the continuous reclaiming of whole tire scrap. Fine mbber crumb (typically 30 mesh) mixed with various reclaiming oils is subjected to high temperature with intense mechanical working in a modified extmder for reclaiming the mbber scrap. 

A technology for the devulcanization of sulfur-cured scrap elastomers was developed, (Kohler and O Neill, 1997a,b) using a material termed Delink (Sekhar and Kormer, 1995), and this technique was designated as the Delink process. In this process, 100 parts of 40 mesh or finer mbber crumb is mixed with 

2-6 parts of Delink reactant in an open two-roll mixing mill. Delink reactant is a proprietary material and its nature and composition was not disclosed. It should be noted that application of this technology to devulcanize synthetic rubbers is more difficult than natural mbber. 

A simple process for reclaiming of mbber with a vegetable product that is a renewable resource material (RRM) was developed (De et al 1997,2000,1999b). The major constituent of RRM is diallyl disulfide. Other constituents of RRM are different disulfides, monosulfides, polysulfides, and thiol compounds.

We started this chapter with a description of the fundamental differences between thermoplastic and thermoset materials we will end it with an example of a subtle blend of their respective properties. A disadvantage of the three-dimensional network of EPDM, but actually of all thermoset materials, is the lack of recyclability. Crosslinked EPDM, both the waste from production and after use, cannot be processed in the melt again like thermoplastics. Reclaiming technologies have been developed for vulcanized mbber, degrading part of the network via high-temperature and shear treatment, but these technologies are less effective for EPDM vulcanizates, probably because the EPDM chains are so stable. A break-... 

Whereas many of these technologies are not really new, they have never had the regulatory and economic justification for their use in metallizing. Each of these general methods has many variants. Some may be directed to waste treatment, some to recycle, and some to reclaim. An example is filtration, used to prevent release to air of zinc particles from flame spraying, microfiltration of cleaners to extend hfe, in combination with chemical precipitation to remove metal particles from wastewater, and many other uses. 

A proprietary form of Caro s acid is sold to the electronics iadustry under the trade name Nanostrip. Used for reclaiming defective siHcon wafers, it is manufactured by Cyantech (United States), Micro-Image Technology (UK), and RASA Industries (Japan).

Reclaim is a passive, in situ technology that uses a hydrophobic porous polymer to attract, adsorb, and concentrate petroleum hydrocarbons and volatile organic compounds (VOCs) from soils and/or groundwater. Reclaim is considered a passive treatment technology because it requires no mechanical equipment remediation consists of placing polymer-filled canisters in recovery wells and allowing the containers to attract and adsorb organic contaminants. Reclaim canisters are then recycled and contaminants recovered for analysis and/or disposal. This polymer extracts contaminants whether they are in liquid phase, vapor phase or dissolved phase in water.
