Description
Rock wool products according to the main performance is divided
into: rock wool board, fire rock wool board, waterproof rock wool
board, stick the aluminum foil rock wool board, high density rock
wool board, rock wool insulation board. Rock wool blanket, rock
wool blanket, steel wire nets rock wool blanket. Rock wool tube,
waterproof rock wool tube, fire rock wool tube, aluminum foil rock
wool tube. Is a selection of high-quality basalt as the main raw
material, after melting the day after tomorrow, adopting
international advanced system of four roll centrifugal cotton
process, to basaltic rock wool high temperature melt into a
discontinuity of the 4 ~ 7 microns fiber, and then add a certain
amount of binder in rock cotton fiber hatred, dust, oil, water,
after sedimentation, curing, cutting, such as technology, according
to the different USES to make series of products of different
density. Also on the surface of rock wool board to stick
moistureproof aluminum foil, black (white) glass fiber cloth
reinforcement glass fiber mat and other decorative and
moistureproof cover.
This company produces the rock wool products, complete
specifications, stable quality, no stimulation to the human body,
is the ideal thermal insulation material, industrial and
construction is also a good sound-absorbing, filter material.
Coefficient of thermal conductivity:
Different coefficient of thermal conductivity of rock wool products
with bulk density and different temperature change, this is mainly
due to the porosity of rock wool products a lot of material in the
heat conduction, convection and radiation heat transfer of three
ways with capacity and temperature variations caused by different
proportions.
The highest temperature of use:
The highest use temperature of the rock wool refers to the
long-term use of it allows maximum temperature. Rock cotton fiber
softening point in *******0 - c, of any change in the use for a
long time not under **0 c.
Incombustible:
Heat preservation field of both construction and other industries,
incombustible materials is very important. Incombustible refers to
the concept of under the condition of a given test, in the test
furnace of **0 c, the sample without any sense of burning.
Long-term use of stability:
Rock wool products with chemical stability, timely in wet or humid
conditions deliquescence long-term use will not occur. Because of
hatred in water, rock wool products almost no water absorption,
according to JISA********9 method to test its hydrophobic rate
above *9%.
Rock cotton fiber has higher heat resistance, good formability and
chemical stability and hydrophobic, ensure the long-term use of
rock wool products.
Rock wool products almost does not contain fluoride, chloride ion
corrosion, such as he had no corrosive to equipment
Sound-absorbing:
For all kinds of industrial noise and house sucking sound energy
received obvious benefits, especially for the high frequency noise
has good sound absorption performance.
Structure: architecture is mainly composed of rock wool board:
bonding layer, thermal insulation layer, plaster, act the role of
the surface and accessories.
Adhesive layer to for the building, is between the bottom and the
surface, first with gelled material will firmly bonding together
two layer, its source and inorganic filler basically.
Insulation layer in order to avoid and cut down the heat loss to
the environment of the steam turbine, the steam turbine and pipe
laying off-grade looks insulation layer, the main filler for rock
cotton fiber and a certain amount of organic matter, moisture, and
adhesive, etc.
Act the role of the surface should be chosen finishing mortar,
ornament mortar lightweight functional coating or outstanding
permeability of water-based exterior wall coating, which makes rock
wool board to keep the characteristics of its light weight, also
increased its beautiful.
Accessories mainly choose all kinds of paint, on the one hand,
increase the surface of the rock wool board color, make its can be
applied to any environment and coating could be partly its role to
the flame retardant and heat preservation.
