1990年1月1日 (3) The slaking rate of pure lime powders depends on the particle size of the powder and the calcination conditions under which the lime was made from calcium carbonate. High calcination temperatures and long calcination times cause coalescence of the lime particles and a reduction of slaking rate.

2014年3月31日 The amount of water used and the temperature reached during slaking affect the particle size distribution of the lime putties. However, in the lime samples slaked with water-to-lime ratios from 1:3 onwards these differences are not significant.

In pharmaceutical research and development, various new chemical entities (NCE) are found to be poorly water-soluble. Therefore, solubility enhancement, a key factor for higher bioavailability, is a major challenge in pharmaceutical industries. Particle size reduction is one such method that increases the surface area of the pharmaceutical compounds and subsequently leads to a

Lime is the most widely used reagent in water treatment applications. It is supplied in two forms: quick lime: CaO; slaked (or hydrated) lime: Ca(OH) 2. Warning: in both cases, these reagents will contain between 4 and 20% of solid impurities (CaCO 3, SiO 2 ). These impurities must be removed before the product is used. quick lime slaking ...

Of these, slaking temperature is perhaps the most important, as it directly influences the particle size of the hydrated lime—and, therefore the reactivity of the slurry. Simply put, the closer the slaking temperature is to the boiling point of water, 212°F (100.0°C), the finer the particle size, the greater the surface area, and

2017年11月1日 It is well known that slaking conditions influence Ca(OH) 2 particle size. Higher slaking temperatures tend to reduce particle size (Zinck and Aube, 2000) whereas some slaking water impurities, such as sulfates, increase particle size (Potgieter et al., 2003). Slaking technologies, including mixing and milling, also influence slaked lime ...
