INTRODUCTION

ROCK

It is a naturally occurring solid aggregate of minerals.

BASALT ROCK

It is an igneous rock formed from frozen lava. It occupies 1/3 of earth’s crust. Plentiful in Michigan’s upper peninsula. In India it occurs in deccan traps .

Page 3: basalt fibre

It is a material made from extremely

fine fibers of basalt, which is composed

of the minerals plagioclase, pyroxene,

and olivine.

BASALT SOURCES FORFIBER PRODUCTION

Temperature history and rate of cooling of

lava

• Slow cooling results in segregation and

precipitation

• Weathering and oxidation over-time

Chemical characteristics and uniformity of

basalt quarry are essential for good fibers.

Manufacturing should be close to suitable

basalt quarries and inexpensive energy.

SPINNING OF BASALT

FIBER Though basalt stones are available in

different compositions, only certain compositions and characteristics can be used for making the continuous filaments with a diameter range of 9 to 24 microns.

Compounds present in the basalt rock may vary, especially the SiO2 content depending on their nature and origin. Basalt rocks with SiO2 content about 46% (acid basalt) are suitable for fiber production.

Page 8: basalt fibre

MANUFACTURING PROCESS OF BASALT FIBREQuarried basalt rock is first crushed,

then washed and moved into melting

baths in gas-heated furnaces. under

temperature of 1460-1500 °C. Here,

the process is simpler than glass fiber

processing because the basalt fiber

has a less complex composition.

BASALT FIBRE PRODUCTION

1. Tank for sizing

2. Furnace

3. Bushing

4. Sizing applicator

5.Tray for used sizing

collection

6. Winder

7. Spool

8. Tank for used sizing

Page 10: basalt fibre

Molten basalt flows from furnace through a

platinum-rhodium bushing with 200, 400 ,800 or

more holes and the fibers can be drawn from the

melt under hydrostatic pressure

A sizing is applied to the surface of the fibers by

a sizing applicator to impart strand integrity,

lubricity, and resin compatibility.

Finally, a winder allows to release some large

spools of continuous basalt filament.

BASALT CONTINUOUS

FIBERS Basalt Continuous Fiber (BCF) is a raw material for the

production of various types of materials & products.

APPLICATIONS

Reinforcing material for concrete & asphalt, concrete

covering for roads, airport runways & taxiways.

Filters for industrial & residential waste waters, filters

for smoke & dust emissions of industrial enterprises.

Reinforcing nets for construction.

BASALT PLASTIC PIPES

Basalt fiber composite pipes are obtained by

winding basalt threads, fabrics, prepegs

impregnated with a binder.

These pipes are useful as components for

shafts linings, building components, for

transporting corrosive liquids and gases in the

construction, industrial, agricultural and public

services sectors.

Basalt pipes are resistant to the action of fungi

and micro organisms.

BASALT SUPER THIN

FIBERS It has good heat-insulation qualities.

The material is absolutely nonflammable, it has

high thermo durability.

High chemical durability towards water, salt

solutions, alkali and acids.

APPLICATIONS :

Fireproof materials of fire protection systems

Heat and sound insulation material for the

manufacture of automobile mufflers, gaskets,

insulation screens, plastics, composites.

BASALT ROVING

Basalt roving is bundle of continuous mono

directional complex basalt fibers.

Roving possesses high natural strength,

resistance to aggressive environments, long

service life and excellent electric insulating

properties. APPLICATIONS: Filament winding of pipes,

tanks and cylinders

Reinforced plastics

Chopped basalt roving is mainly used as a substitute of fiberglass

Page 22: basalt fibre

FIELDS OF APPLICATIONS1.CONSTRUCTION:• Reinforcement of bridges,

tunnels.

• Internal waste pipes

• Repair of cracks, local damage to buildings & bridges.

2.PETRO CHEMICAL INDUSTRIES:

• Chemical & wear proof coverings of tanks.

• pipelines, oil pipelines.• nonflammable coverings &

composite materials.

Page 24: basalt fibre

A distinctive feature of this rebar is high

corrosion resistance to aggressive

environments, namely to chloride salts, carbon

dioxide, nitrogen oxide.

It can even put uncoated chopped fiber

in concrete for crack resistance

High Strength compared to steel.

Light weight and flexibility makes installation

easier.

ADVANTAGES OF BASALT FIBER

Basalt fibers show 15-20% higher tensile strength and modulus.

Better chemical resistance.

Extended operating temperature range.

Better environmental friendliness.

Recyclability.

The processing of basalt fibers does not require special equipment or technologies.

DISADVANTAGES OF BASALT

FIBER

The price of fibers made from basalt is

higher than those made of E-glass.

The American Concrete Institute,

Canadian Standards Association,

International Federation for Structural

Concrete and other internationally

recognized engineering code authorities

have not provided specific design

guidance for its use.

1. Basalt fibers have excellent set of properties like Chemical Thermal Mechanical environmental 2.It can replace glass in large part is widely used in

aerospace, petrochemical, automative and other areas therefore basalt fiber is known as 21st

century “SILK VOLCANIC CHANGE”.As a result of its characteristics and

properties, basalt fiber can be really considered as the material of OUR FUTURE FOR A GREEN AND SUSTAINABLE DEVELOPMENT
