Soft lime

B. Ozonizer. The conversion of oxygen to ozone is accomplished by means of three Berthelot tubes constructed of soft lime glass (Note 2) with the dimensions shown in Fig. 3. It is important that the glass be thoroughly cleaned and that the... 

The potential for expansion because of free lime or magnesia in the steel slag is of particular concern, which could result in pavement cracking if ignored. It is recommended that no detectable soft lime particles or lime-oxide agglomerations be present.36... 

Limestones that are relatively soft, are subject to thermal degradation, or produce a soft lime may not be suitable for calcining in shaft kilns. They may, however, be calcined in certain types of rotary or other kilns (see section 16.4.11),... 

Mari Dredged from dry lake bottoms, marl is a soft lime similar to chalk but has the consistency of clay. It is a composite of clay and calcium carbonate with good water holding capacity. 

When lime-stone is calcined at low temperature, the decomposition of CaC03 is incomplete. The product, which is porous and whose volume is not much less than that of the original lime stone, is known as soft lime. Because, of lower CaO content, soft limes slake slowly.

Soft-burned lime is a quicklime that is calcined at a relatively low temperature. It is characterized by high porosity and chemical reactivity. 

Hardness. Most limestone is soft enough to be readily scratched with a knife. Pure calcite is standardized on Mohs scale at 3 aragonite is harder, 3.5—4. Dolomitic limestone is generally harder than high calcium. Dead-burned or sintered limes are 3—4 on this scale, whereas most commercial soft-burned quicklimes are 2—3 (see Hardness). 

Both of the above extremes are undesirable for most lime uses. Usually, the objective is to produce a completely calcined but soft-burned lime having no core or no more than 1—2% core. Such limes are more porous and chemically reactive. 

Various other soft materials without the layer—lattice stmcture are used as soHd lubricants (58), eg, basic white lead or lead carbonate [598-63-0] used in thread compounds, lime [1305-78-8] as a carrier in wire drawing, talc [14807-96-6] and bentonite [1302-78-9] as fillers for grease for cable pulling, and zinc oxide [1314-13-2] in high load capacity greases. Graphite fluoride is effective as a thin-film lubricant up to 400°C and is especially useful with a suitable binder such as polyimide varnish (59). Boric acid has been shown to have promise as a self-replenishing soHd composite (60). 

Lime and Lime-Soda Processes. The first softening plant in the early 1900s used the lime softening process with fill and draw units. Later, continuous-treatment units, which greatiy increased the amount of water that could be treated in a faciUty of given size, were developed. More than 1000 municipahties soften water. Most are in the Midwest and in Florida. However, concern for the adverse effect of soft water on cardiovascular disease (CVD) may limit the number of plants that introduce softening. 

Colas represent the largest segment of the U.S. soft drink market followed by lemon—lime brands. Pepper-type, juice-based, toot beer, and orange flavored soft drinks represent two to five percent of the total soft drink market (Fig. 4). Diet and caffeine-free categories represent the fastest growing segments of the market. 

Calcium Oxide. Also called lime or quicklime (4,5), calcium oxide [1305-78-8] (Class 1, nonregenerative), is relatively iaexpensive. It is prepared by roasting calcium carbonate (limestone) and is available ia a soft and a hard form according to the way ia which it was burned. For desiccant service, soft-burned lime should always be used. Calcium oxide is most commonly used to dehydrate Hquids and is most efficient when it can be heated to speed the reaction rate. The reaction product is calcium hydroxide, which cmmbles as it picks up moisture. 

Milk-of-lime transfer pumps should be of the open impeller centrifugal type. Pumps having an iron body and impeller with bronze trim are suitable for this purpose. Rubber-lined pumps with rubber-covered impellers are also frequently used. Makeup tanks are usually provided ahead of centrifugal pumps to ensure a flooded suction at all times. Plating out of lime is minimized by the use of soft water in the makeup tank and slurry recirculation. Turbine pumps and eductors should be avoided in transferring milk of lime because of scaling problems.

The most important property of the dissolved solids in fresh waters is whether or not they are such as to lead to the deposition of a protective film on the steel that will impede rusting. This is determined mainly by the amount of carbon dioxide dissolved in the water, so that the equilibrium between calcium carbonate, calcium bicarbonate and carbon dioxide, which has been studied by Tillmans and Heublein and others, is of fundamental significance. Since hard waters are more likely to deposit a protective calcareous scale than soft waters, they tend as a class to be less aggressive than these indeed, soft waters can often be rendered less corrosive by the simple expedient of treating them with lime (Section 2.3). 

Therefore, for the treatment of soft or aggressive waters, the use of C02 in combination with lime or calcium hydroxide is advisable to increase water hardness. This process is called remineralisation and is meaningful in water treatment plants, because soft water is indigestible. 

Aggregates of soft powdery lime indicate absence of churning, unless such aggregates are very small and form rapidly. Soft powdery lime is a substratum feature in Vertisols. 

A wide range of substances is permitted for alternative crop production. For example, LOJ, Denmark is the only certifying body reviewed so far that provides maximum concentrations of solutions of sulphur, soft soap and mineral oils. Furthermore, several substances permitted by IFOAM and EU standards are not allowed, such as pyrethrum, copper salts, chloride of lime and soda, or microbial pest controllers. Spain (CRAE 1994) stands on the other end of the spectrum with their exclusive focus on the EC Reg. 2092/91.
