Abrasives are substances both natural and synthetic that are used to grind, polish, abrade, scour, clean, or otherwise remove solid material usually by rubbing action (as in a grinding wheel), but also by impact (pressure blasting). The most important physical properties of materials that qualify as abrasives are hardness, toughness (or rigidity), grain shape and size, character of fracture (or cleavage), and purity (or uniformity). In the final analysis, the choice of a high-grade abrasive depends upon the quality and quantity of work performed by the abrasive per unit of cost. Initial cost of an artificial abrasive may be much greater than that of a natural abrasive, but the artificial mineral may do so much better work and do it so much faster than the ultimate cost is less. It is for this reason that artificial abrasives have largely replaced natural abrasives. Chemical Properties: Purities are available from PreRish Tri sometimes as high of a typical purity as 99.999% down to low purity recycled abrasive grains or powders Physical Properties: Numerous shape and size options are usually readily available from READE as large as 50 mm grinding and tumbling media down to as small as 20 100 nanometer particles. Typical Applications: Buffing, coated abrasives, coatings, deburring, electrical potting insulation, fillers, fining, flow finishing, friction, grinding wheels, heat transfer component, investment casting molds, wear resistant parts, metal lapping, polishing, pressure blasting, slurry sawing, tumbling, ultrasonic machining.

Electroplating wastewater include the pretreatment rinsing wastewater, plating rinsing wastewater. And the principal pollutants are heavy metal ion . 1.1 Up-to-standard discharge technology The emission of waste water which contains heavy metal ions such as Cr, Cu and Ni must meet the local requirements by adopting the means of Physical and Chemical Reaction + Sequencing Batch Precipitation + Ion Exchange + Compulsory Filtration to reach the standard. 1.2 Electroplating wastewater reuse technology Electroplating wastewater reuse technology means to add reclaimed water reuse system and reuse system on the basis of standardized discharge technology. The effluent can meet reclaimed water reuse standards(such as cleaning). 1.3 Electroplating wastewater zero-discharge technology MVR evaporator Working principle: MVR evaporator will increase the energy of secondary steam by using compressor, and will take advantage of the secondary steam with improved energy to recycle the potential heat of secondary steam. Specifically: Increase the pressure and temperature of the secondary steam generated by evaporator through the adiabatic compression in compressor, and after that, the steam will be fed into the heating chamber of evaporator (heat exchange system) as the heating steam, thus the potential heat of steam can be reused. The cold material will absorb the heat of non-condensable gas through preheating exchanger before being sent into evaporator, so the temperature of the cold material will increase, meanwhile, the condensate can be cooled by this material. This can further improve the utilization ratio of heat.
