The basalt fiber chopped strands or chopped basalt fiber for reinforcing concrete is mainly replacing the alkali-resistant fiberglass (AR-glass) chopped strands. Normally, the tensile strength of basalt fiber should be twice more than the one of AR-glass in the concrete. However, a good ...
The basalt fiber is just a new product compared to other reinforcing fiber so it is very young and need to have very clear blueprint for the technology, management and scale development. First of all, for the technology, this is the fundamental issue that basalt fiber manufacturer and ...
Not all of the basalt stone can be used to produce basalt fiber, especially the FeO/Fe2O3 portion, Ca and Na elements should be restrictly required. For the material stable performance and consistency, the basalt stones should be firstly tested to get the element analysis then all the required stone...
For normal fiberglass manufacturer, there are at least hundreds and thousands of sizing formulas they can use such as, filament winding, pultrusion, weaving, spray-up, hand lay-up, chopping, mat-use, SMC, BMC, transparent panel and so on. For a special resin and process method, there wil...
Talking about the basalt fiber production process engineering, we will start with the production line design. Normally, production process is a macro-angle view which includes furnace design, bushing design, fabrication and installation, rolling machine, fiber drawing machine and so on. In this arti...
Nowadays, the basalt fiber bushing design and fabrication technology seems to be not as advanced as fiberglass bushing. Because of the sticky melt basalt and its unique narrow temperature control zone of fiber forming, basalt fiber bushing should be different from the fiberglass bushing such as Rh e...
Right now, the furnace of basalt fiber is just one furnace with one bushing production line. The efficiency is not high and the goods quality is not stable. The annual production capacity can not be more than 100 tons. So to build bigger furnace, for example 2000 tons production line should be manuf...
Nowadays, basalt fiber industry is against fiberglass (including Alkali-resistant fiberglass, E-glass and ECR-glass), carbon fiber, aramid fiber, polyvinyl fiber and so on. However, the major competitors are e-glass, AR-glass and carbon fiber. For the first stage, because of the basalt f...
In AR-glass fiber, the alkali resistance property is the key factor in the fiber manufacturing that is supported by the heavy metal oxides. The 15% consistence of ZrO2 determines AR-glass good qualities in concrete reinforcement process. High consistence of iron oxides (12÷14%...
As to the thermal extension coefficient, basalt fiber is very close to concrete than other conventional reinforcements – steel or AR-glass. According to its parameters, basalt fiber is the most compatible one among concrete reinforcement materials. The detailed data are as foll...
