General building exterior wall insulation
materials include: inorganic active external wall insulation materials,
silicate insulation materials, rubber powder polystyrene particles, steel wire
net cement foam board etc. These materials are not ideal for fire protection
and environmental protection performance. Now we introduce rock wool panel, it
is a natural environmental protection type fireproof, adiabatic thermal
insulation material. It uses natural rock and blast furnace slag. As the main
raw material, plus a certain number of auxiliary materials, artificial fibers
are made by melting injection at high temperature, and then rock wool products
(rock wool color steel plate) are made with it. Rock wool color steel plate has
passed the national fire prevention test, and its performance characteristics
are as follows:
1. Rigidity is good: Because rock wool core
insulation and two layers of steel plate are bonded together to form a whole
and work together, and the surface of roof panel is corrugated and pressed, its
overall stiffness is much better than that of rock wool (glass silk wool)
in-situ composite plate. After the sandwich paneling is fixed with purlin by
connecting parts, the overall stiffness of the roof is greatly improved, and
the overall working performance of the roof is strengthened. When rock wool
sandwich board is selected, a larger purlin distance can be adopted, thus the
purlin consumption can be saved by 1/3~2/3.
2. Reasonable buckling mode: Rockwool sandwich
roof panel adopts buckling connection mode, which avoids the hidden danger of
leakage of roof panel joints and saves the consumption of accessories.
3. Fixing method is firm and reasonable:
Rockwool roof panel is fixed with special M6 self-tapping screw and purlin,
which can effectively resist the external force such as typhoon. Self-tapping
screw is set at the wave crest position on the surface of roof panel, and
special waterproof structure is adopted to avoid waterproof weak points.
4. Installation cycle is short: Rock wool sandwich panel can not only keep the surrounding environment clean without
affecting the normal operation of other processes, but also greatly shorten the
installation cycle of the board. The average daily installation area of rock
wool sandwich panel reaches 600-800 square meters.
5. Scratch protection: When rock wool
sandwich board is produced, polyethylene self-adhesive protective film can be
pasted on the surface to avoid scratch or wear on the surface of steel plate
during transportation and installation.
6. Excellent fireproofing performance: Rock
wool sandwich board uses raw materials, production process and formula, so that
it has good fireproofing performance.
7. Good thermal insulation: thermal
insulation is based on the thermal conductivity of rock wool 0.043W/m2K and the
thickness of rock wool core material in corresponding proportion. Fire
protection grade: A
8. The effect of sound insulation and
absorption is remarkable.
Sound absorption: It can absorb sound in a
wide range of frequencies. According to ISO354/85 standard, the sound
absorption performance of rock wool board reaches DELTALA=15.7dB(A).
Sound insulation: Rock wool sandwich board
can significantly reduce noise transmission, especially in places where
designated flights pass. In addition, when rock wool roof panel is used, indoor
sound caused by rain and hail impact on roof panel of buildings is also
significantly reduced. Through testing, according to ISO717/82 and UNI8270/7
standards, the sandwich board with density of 100kg/M3 rock wool as core
material is selected. The sound insulation effect can reach RW=29~30Db.
