6. Production technology:
According to raw material's category, quality and
technological characteristics of main equipments, etc, different
technologies can be adopted to produce aerated concrete block.
Generally, fly ash or silica sand is grinded into slurry with
water, and then mixed with lime powder, proper cement, gypsum and
aluminum powder paste and finally filled into mould. After
maintaining, foaming and solidifying, blocks or plank of different
specifications will be cut out and conveyed by trolley into
autoclave. Under the high temperature and saturated steaming
curing, celluar and light-weight aerated concrete products will be
formed. The steps are as follows:
(1) The raw materials such as lime, cement, gypsum,
sand(or fly ash), etc are stored in silo(tank) for use after
treatment.
(2) Aluminum powder or aluminum paste is stored for use
after treatment.
(3) Raw material is measured by electrical scale with
certain proportion. After measured, aluminum powder and water are
fed into aluminum powder mixer to make into suspension
liquid.
(4) Water for proportioning( cold water or hot water
from hot water tank) is measured by electrical scale
(5) After measured, raw materials and aluminum liquid
are fed into casting mixer orderly to be mixed evenly and cast in
moulds(if making plank, then reinforcing mesh should be put in the
mould before hand)
(6) After stopping and precuring under certain
temperature for certain time, the green blocks will reach to
certain strength. And then they are turned *0
