一、Aerated Concrete Equipment introduction：Aerated concrete products in foreign countries and now have nearly
a hundred years of history, has become a pillar industry of the
construction industry, introduce the technology in China nearly
four years of history, its production equipment, mature technology
and equipment. As the bulk density of aerated concrete has a light,
high performance thermal insulation, sound-absorbing effect, there
are certain advantages of strength and process ability, and
abundant raw materials, particularly the use of fly ash as raw
material, which can be comprehensive utilization of industrial
waste, environmental pollution without destroying farmland, but
also to create a good social and economic benefits, is a reasonable
alternative to the traditional solid clay phase of the wall
materials, wall materials innovation over the years by national
policy, tax policy and environmental policy support, plus gas New
Building Materials Concrete Products has become an important part
of a broad market prospect.
二、Aerated Concrete ProductionAerated concrete can base on raw materials category, quality and
process characteristics of major equipment, adopt different
production processes. However, under normal circumstances, the fly
ash or silica sand ground into a paste with water, adding powdered
lime, regular cement, gypsum and foaming agent, was injected into
the mold by mixing box, static oxygen foam cured, cut into a
variety of specification block or plate, keep a car from the steam
into the autoclave, in the high temperature vapor that is formed
under the conservation of porous lightweight aerated concrete
products.
First, the raw materials will be stored by the measurement of
ingredients (1) after pouring into the mixer, by mixing (2) even
after the pre-pouring temperature and time dependent (4) green body
to a certain hardness, by the turn to die and billet spreader body
hanging to the cutting machine. Flip spreader to complete the
following features: a to die in the air for 90 degree turn (5)
(mold side of the board as supporting green body until the steam
curing the finished floor), b hanging rack carrying car or cutting
support to complete mold, mold release (6), c take off the mold box
and return to the steam curing side (16) and then reassembled into
a mold (17) wait for the clean-up after the injection (18)
re-casting. Body step by step in the cutting machine for six-side
cutting; a first for the vertical sides of cut green body (7), b
and longitudinal horizontal cut (8); c Finally, lateral horizontal
cut (9). Segmented by the semi-green body with floor spreader crane
to raise steam car (10), and then incorporated into the autoclave
(11) for high-temperature steam curing (12), after a good steam
curing kettle (13), hanging from the finished product with the
finished product stacking (14) or loading, packing (15), steam
curing side returns (16)
三、producing equipment
Aerated concrete production equipment selection and process design
is according to the number of programs to determine, according to
process design; casting is divided into two kinds of fixed and
mobile casting. Turn cutting is the main cutting way in China,
other mixing system: like autoclaved equipment maintenance and
other equipment are similar.
