Metallography. In Smithells Metals Reference Book (Eighth Edition), 2004. CHEMICAL POLISHING. Chemical polishing is adopted usually as a quick method of obtaining a passable result, rather than as a method of preparing a perfect surface. However, where it is difficult to prepare a deformation-free surface by other means, as with some very soft …
Cement acts as the binder between aggregates (fine and coarse rocks) in the formation of concrete. While cement makes up only a small percentage of the mix (approximately 12 percent by volume), it is almost exclusively responsible for the resulting CO 2 emissions. In the cement-manufacturing process, raw materials are heated to high …
Berlin / Johannesburg / Dauerthal – Global chemicals and energy company has joined Concrete Chemicals project, an innovative consortium of 's new business unit ecoFT, global cement producer CEMEX and German renewable energy company ENERTRAG. The international consortium sets course for climate-neutral …
The production of cement leads to a large amount of CO2 emission. Using industrial waste slag, such as ceramic polishing powder (PP), to replace part of Portland cement can reduce the pollution caused by the cement industry and solid waste …
Condensate Polishing is a process deployed to remove contaminants from condensate streams like steam, turbine and process condensate, before it is returned to the boiler/heat exchangers. It is highly important to remove traces of soluble inorganic impurities present in the feed water, as they may get concentrated within the system. Tulsion ...

CMP (Chemical Mechanical Polishing/Planarization) is a highly precise polishing process. It combines two specific actions. Firstly, the process modifies chemical properties of the substrate by chemical agents. Meanwhile, highly designed abrasive particles are performing the mechanical treatment. Properties of the process. Experts recommend chemical …
Chemical-mechanical planarization (CMP), a key manufacturing step enabling the continuation of Moore's Law, is increasingly employed also for the fabrication of "More than Moore" devices. In this chapter, the application of CMP for power transistors, MEMS and micro-opto devices and wafer bonding will be discussed in detail and examples of ...
Penetrating chemical hardener. After performing initial coarse grinding with the metal-bonded diamond abrasives, it's often beneficial to apply a liquid chemical hardener to the concrete to help solidify and densify the surface and provide extra protection from water penetration and staining. Hard concrete also produces a better polish.
