Cold Pressure Wall Panel Making Machine for Fiber Cement / Mgo
Sandwich Board
New-type (Mgo) Sandwich Wall Panel Making Machine/fiber cement
sandwich wall board machine
I Equipment Feature
This machine adopts the technology of double-drive
double-roller-extruding, and the product is formed once after
sizing, material feeding, spreading
no-woven cloth, compounding and repressing. The equipment runs
stably with high
automatic degree, and the specification of its product can be
adjusted arbitrarily.
The equipment actually realizes the industrial production-line of
new model building
wall board, and the product have even and glazed surface with high
compactness.
The equipment largely reduces the labor intensity of worker and
thoroughly changes
many shortages of the former casting forming with upright mould or
flat mould,
such as large mould usage, low recycling rate, required electrical
heating or steam
heating, single kind of product as well as the sound insulation and
heat-preserving
which don’t meet the market requirements.
II Project Feature
1. The source of the production raw materials is widely with no
regional restriction.
The product is made of sawdust, straw (rice hulls), many kinds of
crop straw and
inorganic material (such as talcum powder, infusorial earth and
powder coal ash)
after special technology. So this project have low production cost,
small investment
and fast effectiveness.
2. The equipment has high automatic degree, simple production
technology, low
labor intensity and production line, and there is no noise and
three-wastes (waste water, waste gas and waste residue) during
production.
3. Low production energy consumption. With the influence of
chemical reaction, it
can meet the requirements about production technology without high
temperature
and high pressure.
Product Feature and Performance

III Feature
1. Anti-earthquake with light weight: In view of its weight per
unit area is only 1/10
of red brick wall, the product has good anti-earthquake
performance. It can be used
at low-rise building and high-rise building, and it is preferred to
be used at workshop
with steel frame structure. It can replace the color steel plate
with its better
performance.
2. Fast and convenient operation: It can be installed by board or
combination with
the dry method, and the product can be nailed, cut, planed, drilled
and stuck.
3. Low comprehensive cost: The product is made of agricultural and
industrial
wastes, so the production cost is low. With the low load of girder
and short
construction period, it can reduce over 20% of engineering cost
after compared with
solid brick and hollow brick.
4. Energy-saving and environmental protection: The production
processing need no high
temperature and high pressure. Being a green
environmental-protection energy-saving building materials, the
product has no toxicity, harm, pollution and
radioactivity.
5. Increasing the usage area: Under the same condition of
heat-preserving and
sound insulation, with the thinner plate, the product can increase
over 10% usage
area after compared with the same building.
6. Having the following features: fireproofing, water-proof,
anti-impact, acid & alkali resistant and anti-aging.
