Basalt continuous fibers materials production

It is more profitable to remake primary BCF materials into finish BCF products. Organization of based - basalt continuous fiber materials production is very important and key question for improvement of the economic indexes of the BCF production. At the first stage it should be basalt chopped fiber, basalt-plastic rebar, basalt-plastic rods and structural shapes; at the next stage - production of basalt-plastic pipes and composites of various shape, geo grids, meshes and reinforcement nets and various fabrics.

Chopped basalt continuous fiber (BCF chopped fiber)

Chopped basalt continuous fiber (BCF chopped fiber)Chopped basalt continuous fiber (BCF chopped fiber) BCF chopped fiber will be used in great demand at the building and road construction for reinforcing of concrete and asphalt- concrete. Using of basalt chopped fiber is one of the effective and perspective methods for strengthening of characteristics of concrete, which are using in the building of foundation, piles, wall panels, slab floors, finishing cement covering, and for reinforcing of asphalt-concrete road.                       

For volumetric formed reinforcement needs about 1, 5–2 kg of basalt chopped fiber for 1 metric cubic concrete (one cubic cm includes about 100 filament fibers with diameter of 15-18 microns and length of 12mm).

 
Results of volumetric formed reinforcement is the hardening of concrete, including:
  • Compressive resistance to be increased by 20 - 25%;                                       
  • Tensile load on bending - by 200 – 230 %;             
  • Refinement of freeze resistance by 1.6 – 2 times;
  • Gain of crack growth resistance under load and dynamic load.                                   

Good results give reinforcements of the finishing covering of the floor.   BCF can not destroy or damage under the influence of MOISTURE, SALT and SEA WATER.

See article. « Application of BCF-based materials in construction»

There are two types of the equipment for chopping basalt fibres, including: the simplest machines for chopping of rovings and more productive installations for chopping the bundles of primary fibres (filament) in the process of their production (immediate chopping).  Installation for multi-passage drawing and chopping of primary BCF-bundles is used at the big production volume of chopped BCF. 

Production of composite basalt-plastic materials and products. Basalt-plastic rebar. Section materials. Pipes.

There are three types of the process equipment (pultrusion lines) for production of basalt-plastic rebar and section materials.

Bobbin carrier for basalt fiber roving and the section for installing the bobbin carriers for feeding basalt fiber roving to the pultrusion process lineBobbin carrier for basalt fiber roving and the section for installing the bobbin carriers for feeding basalt fiber roving to the pultrusion process linePultrusion process line for the production of basalt-plastic section materials and rebarPultrusion process line for the production of basalt-plastic section materials and rebar

Process line for manufacturing of basalt-plastic rebar

Basalt-plastic rebar of two types and basalt-plastic rods

Lately, production of composite materials based on basalt fiber has significantly increased, and conventional metallic materials are substituted with light durable composite materials in automobile, municipal service, chemical, power, and construction industries.  Basalt-plastic rebar have strength which is 2 … 2.5 times higher than the strength of steel reinforcement,  are 6 … 8  times lighter than steel rebar, are not subject to corrosion, and have no fatigue cracks in long-term service and under alternating loads. The cost of BPR is lower then the cost of analogous steel materials at 10-20%. Basalt-plastic reinforcing (BPR) have advantages when used in the production of no tensioned concrete products and road slabs. At the present time, the use of basalt-plastic reinforcing materials is sufficiently regulated. The corresponding tests of such materials were performed and normative documents - specifications and standards for the use of BPR have been developed by design institutions in Ukraine, China, and Russia and some other countries. In USA Standard ASTM for Composite reinforcement was developed.  With consideration of these factors, continuous basalt fiber is perspective material, specifically for use in production of basalt-plastic composite materials.

The advantages of composite Basalt-plastic pipes, tanks and reservoirs, high pressure cylinders over steel materials and products are the following: higher chemical resistance to aggressive media and corrosion, longer service life, lower density (the weight of basalt-plastic pipes is about 6 -8 times lower at the same strength), and higher strength properties; no need insulation and carrying out of welding works

Production of the Geo- textile road meshes and construction meshes

Toughening of requirements to the quality of road construction, operation and maintenance of road pavements entails the use of new reinforcing and geo-textile materials.
State Standard for application of Geo- textile road meshes in road construction were developed and introduced in Europe, USA, PR China, Ukraine, Russian Federation and other countries.  Materials made of whinstone-based continuous fibers possess fairly high strength properties, chemical and thermal resistance, and to the fullest extent meet the requirements to road pavements. The use of BCF-materials for motor-road construction and repair works decreases the total cost of their fulfillment and considerably increases operational lifetime, as well as overhaul life of road pavements.

Road meshes are manufactured from BCF-roving, warp-wise and weft-wise, and are interknitted with twisted thread using knitting-and-punching machines. Then, they are permeated with bitumen compounds in dipping tanks and are heat-treated (polymerized and dried) in driers.

To manufacture construction meshes (with the cells 4x4 mm and 5x5 mm), the special looms are used for netting meshes from twisted thread.  Then, the interknitted meshes are permeated with latex and silane compositions, polymerized and dried in driers. The reinforcing meshes are used in construction and also for reinforcement of cutting and abrasive wheels
