Description
Technical field
The present invention relates to a kind of production technique of inorganic non-metallic fiber, relate in particular to the production technique of the pure basalt continuous fiber of a kind of high-performance novel high-strength.
Background technology
The basalt continuous fiber high-strength light, and have excellent properties such as high temperature resistant, anti-oxidant, radioprotective, thermal insulation, insulation, sound insulation.Can be widely used in fields such as fire-fighting, environmental protection, Aeronautics and Astronautics, military project, automobile, shipbuilding, communications and transportation, electric, equipment protection, communal facility, chemical building, simultaneously; It in process of production; No obnoxious flavour, discharge of wastewater; Not producing waste residue, is pollution-free not carcinogenic green material.Basalt continuous fiber is to be the filamentary material that raw material is processed by natural basalt, however the difference at the zone that distributes because of its Irish touchstone ore, ore deposit point, aspect, position, its basic oxide compound attribute content also there are differences, and the Chemical Composition fluctuation is bigger.And wherein some oxide compound fusing point is higher, do not have fixed fusing point, melt diathermancy poor, be prone to crystallization, material property is short, wetting angle is little.Thereby, be difficult to stably produce high performance high-quality basalt continuous fiber according to existing manufacturing technique.Some producer is in order to pursue manufacturability; Production technique with reference to glass; Artificially having added some other raw mineral materialss makes up; Had a strong impact on the due quality of basalt continuous fiber, caused the reduction of the fundamental propertys such as intensity, chemicalstability, thermostability of fiber, so press for research and development and improve a kind of comparatively production technique of suitable high-strength pure basalt continuous fiber.
High-strength pure basalt continuous fiber, be by a kind of natural basalt as single component raw material, be pulled through founding.Irish touchstone is to be formed after cooling off by the lava flow that volcanic explosion is sprayed and spoiled over out; Because of the abundant fusion migration of the lava high pressure-temperature in 1 years of magma chamber under the earth's crust; Spray and spoil over through outburst suddenly again; So lava is the slaking homogeneous already, toxic gas volatilizees totally already, and has characteristics such as significant acid and alkali-resistance, high temperature resistant, physicochemical property be stable.
Irish touchstone is the product of volcanic explosion, and is very wide in distribution on global, and volcanic explosion is the geological phenomenon of Earth Activities, has with living.Because of differences such as its geological age, regional distribution, tectonic structure, power mechanism, magmatic origin, migration process, land occupation conditions; And general Irish touchstone mineral deposit is many at the repeatedly dissimilar compound ore body of the stratiform that outburst built up of different periods warps; So the Irish touchstone ore between different distributed areas, ore deposit point and each aspect, the position, its oxide compound attribute and content and Chemical Composition all have than great fluctuation process.
Summary of the invention
Influence the due quality of basalt continuous fiber in order to overcome the deficiency of existing technology, to solve, cause the problem of the fundamental property reductions such as intensity, chemicalstability, thermostability of fiber, a kind of high-strength pure basalt continuous fiber production technique is provided.
