HYDRATED LIME
Quicklime can
also be hydrated with water, in a process commonly referred to as slaking,
resulting in HYDRATED QUICKLIME (or calcium hydroxide), a dry free flowing
powder product that is practical and efficient for many uses.
INDUSTRIES WHICH ARE USING HYDRATED
LIME AND THEIR USAGE PURPOSE:
Construction:
Lime
stabilization for roadway construction,
As an
additive in HMA for multiple benefication,
In AAC
production,
In calcium
cilikate brick production,
In concrete
block and some component production to increase the its strength,
It is using
as a binder for production of the mortar and plaster, and using as a limewash
to increase the workability of mortar.
Hydrated Lime for Increasing Asphalt
Durability
Hydrated lime
is used as an additive in asphalt. Hydrated lime improves the cohesion of the
asphalt binder to the aggregate particles, making the asphalt pavement less
sensitive to moisture and reducing "stripping." Hydrated lime retards
the asphalt aging process and improves stiffness properties. Hydrated lime
helps reduce asphalt pavement rutting and increases fatigue resistance to heavy
wheel loads, a cause of pavement cracking. Adding hydrated lime to asphalt
significantly increases pavement life and serviceability.
Hydrated lime
Mining Industry:
Hydrated lime
is using for floatation of the some ore like copper, lead, zinc as a ph
regulaor and pirit supressor,
is using as a
binder for pellet of the iron ore and pellet production which has naturally
contain slug.
Metal Industry:
Hydrated lime is using for leaching
gold by cyanide method as a ph regulator.
Paper Industry:
Flue Gas Treatment:
Chemicals:
Water Treatment:
Waste Water Treatment:
Precipitation
of the solids by using hydrated lime and recovery of the alcohol, calcium
lignosulfat by using HL as a filtration contributer.
Desulphurisation
of the SO2 and SO3 by using Wet and dry fgd methods,
HCL cleaning
in the waste incineration system,
Capturing
some heavy metals by using HL and active carbon.
Calcium hypo
chlorite production by reaction of the hydrated lime and Clor,
Rafination of
the citric acid,
Some type of chemicals
production by reaction of the organic and inorganic acid with HL,
and it is
used in the chrome chemicals production as a neutralizer, in the ethylene or
propylene production phase.
Decreasing
the hardness degree of the carbonat in the water, decreasing the hardness
degree of the other elemnets in the water lime/soda process,
Precipitation
of the solids in the water by using HL, aluminium and iron powder, neutralizing
acidic water,
Increasing
the PH value in the water in order to remove bacteria and some virus.
In the waste
water treatment, precipitation of the solids in the water by using HL,
aluminium and iron powder, removing phosphor and nitrogen,
Neutralisation of the
acidic water in the ındustries, precipitation of the some metal ions like iron
and chrome, clarifying water in
