Description
Vermiculite in Industrial
Applications
A.Seal and Seal
ring
One of the most important use of
vermiculite is to protect the components of catalytic converter on
theautomobile.A a good example
is a USA company use large quantity of vermiculite to produce this
components. And also there are other famous company using
vermiculite produce similar products.
B,Fireproof
Cause the reason that vermiculite
is ideal fireproof material .which is widely applied on high
temperature furnace ,oil industrial ,underground construction,smelt
the coat of metal and fireproof safe deposit box and fireproof
door.
C. High temperature insulation
materials use on steel factory and Metal Casting
The features of heat
insulation ,low density , natural heat resist and easy handle
makes vermiculite to be the suitable material applied on
steel factory and metal casting on the purpose of
wrapping and covering the melted steel and metal to keep
warm and prevent heat lose .
D.Packing material
Expanded vermiculite is a
very practical material .They are not only very light ,
environmental
protection,easy
packing the irregular products ,but also
a good cross
wall
To prevent middle and bad chock
occurred during the wrong moving .It is mainly used to wrap
harmful chemical liquid , chemicals and easy overflow accidents
.Expanded vermiculite also used to storage the fruits and
phosphorus stem tuber plant.Due to the feature of soft, durable
heat resist ,it is also large used as a stuff of swimming
base.
E.Animal feed
With the characters of soft
, sterility,good
liquidity,powerful absorption ,vermiculite could be used as a
additive or carrier of many nutrient,such as enrichment fat,
vitamin preparations,honey .The application of
vermiculite could enlarge the output ,help gastric absorption and
easy to mixed with other feed.
F. Processed
vermiculite
Vermiculite could be milled or
mould pressing according to the needed size before expanded or
after expanded.This grinding material could be used to produce
sound-absorbing paint ,high performance seal and seal ring,and
improve the the fireproof abililty of organic foam and other
polymeric material.Vermiculite also could be colored according to
the use.
G.Friction plate
Vermiculite now widely used on
producing fricton plate ,such as break ,clutch plate . which is a
safe replacement of asbestos .It is important material in this
area.
H.Fire resist products
Vermiculite as high
temperature insulation materials or fire resist products often
used together with alumina cement, coal clay and silicate to
produce many serials of vermiculite products.According to the types
of the products and application ,vermiculite could bare ***0
centigrade temperature .Vermiculite fire resist products including
:firebrick which baked with coal clay.A replacement of alumina
concrete. High alumina mixed brick .Plate and other special section
, Mixed silicate insulation material and casting products.
Compressed vermiculite could be used on high temperature brick
furnace .steel furnace, destructor,boilor , wooden burn furnace and
caliente fornalia.
Application of vermiculite on
agricultural
Soil conditioner
Under whatever
condition,vermiculite could be used to improve the soil ,for
example ,it could soften the soil, So it is widely used as a media
of the growth of plant.
Fertilizer
carrier.
When vermiculite used as a
carrier or additive of fercilizer ,we often use the no 4 or smaller
size one . Besides,It is also used as a carrier or addictive
of herbicide and pesticide.It could makes a good
liquidity
Garden
Expanded vermiculite is a good
growth media of the seed. Especially used on the sand , peat moss
and the not fertile land. It has the ability to adjust the
changeable temperature and moistures.It is often used to produce
the mixed fertilizer .The existence of vermiculite in the mix
fertilizer is helpful for the air flow,keep moisture ,and
improve the release of the fertilizer .And also could be used as
mixture of pot-planting widely used on soilless culture.
Hydreoponics
Expanded vermiculite is the main
element of water load method system.The principle of the
Hydreoponics is very simple ,the liquor could Concentrated
provides nutrients for the plant .Thus the plant donn’t need
to waste energy to mineralize its root instead to put its
energy on the leaf and fruit .Plant could growth among few soluble
chemical water.But vermiculte have three elements of the four
nutrient: calcium ,magnesium. Kalium
Vermiculite used on
construction
A.Bituminous coating vermiculite
plate
When vermiculite was coated with
bituminous,it could be used on the roof plate .Such plate have
the features of heat insulation, moistureproof,east to storage
.
B. Construction
painting
Vermiculite coating is a
basic light material,have many use.But the most important use is to
be a protector of the high building and other buildings.
Vermiculite could be ues to prevent the destroy to steel when
occurred the fire.Under **0 centigrade the steel will bend.This
will cause the collapse .But if the cement contain the vermiculite
will extend the time of the collapse.And save time let the
inhabitants to move out and also prevent the destroy of t he
steel.
C.light concrete
Light concrete is very light and
have good insulation characteristic.It is a natural born fireproof
material.Vermiculite concrete could be used on roof and floor
and other concrete production..It could be also used on boil wall
and other fireproof wall materials.
D.Stuff of the insulating
material
Vermiculite
stuff could be used on the pavilions beam with the function to keep
warm.Expanded vermiculite have good flowability,this make it easy
to install.Cause the light quality ,it is used to reduce the
density of the construction.This greatly improve
thesound insulation
of the door ,top and proof of the construction
E.Vermiculite
plaster.
Vermiculite plaster could
be produced from gypsum and cements.The advantage of the
vermiculite are :it can improve the effect of the covering. light
quality ,durable ,fire resist ,reduced thermal conductivity,
strengthen adherences, high crack wrinkle resistance,No
matter vermiculite gypsnm or vermiculite cements ,it could be paint
by person or machine, As a friction material ,vermiculite are very
suitable to spray. And such spray application could cause very
attractive effect .
F.Fireproof
plate.
Vermiculite could be used to
produce plate, The raw high grade vermiculite concentrate could be
added into the plastic plate to improve the fireproof. This is
largely and widely used at the moment.
