Calcination of high calcium carbonate rock minerals occurs at ~900°C and atmospheric pressure yielding the highly reactive calcium oxide or 'quicklime' (CaO), which can then be hydrated to the hydroxide form Ca(OH)2. This is achieved either using steam to produce a dry hydrate, or by slaking in water to produce a wet putty.

Dispersion experiments for 3000mesh calcium carbonate showed that DispersantB had the highest dispersing capability of the four dispersants. The dispersing capability of DispersantA was close to that of Acumer9400, but higher than that of SP40M at the dosage range of ‰. DispersantB and SN5040 were the suitable dispersants for the ...

Many greaselubricated machines operate in wet environments, and are vulnerable to contamination because of water exposure. Reports suggest that even the presence of 1% water in grease reduces the life of a bearing by 90%. Nevertheless, only a few qualitative tests and standards are available to characterize the water resistance properties of greases. In this paper, we propose a standard for ...
