It sets；3) viscosity for improving basalt glass influences the uniformity of basalt glass；4) not only increase production cost on raw material,
Change production technology but also the production cost increases.
Author has found in the research of early period, the tensile strength of continuous basalt fiber and basaltic main chemical component
SiO2Content, host component (quartz, orthoclase, plagioclase and pyroxene) and melt homogenize it is related.Continuous basalt
The tensile strength of fiber is with SiO2The increase of content and improve；As quartz, orthoclase close the increase of plagioclase content and rise
Height is reduced with the increase of pyroxene content；The homogenieity of Basalt melt is better, is more conducive to improve basalt glass melt
Homogenieity, to be conducive to the promotion of the tensile strength of continuous basalt fiber.And basalt glass melt homogenize with
Basaltic production technology performance, such as: viscosity, fusion temperature, crystallization ceiling temperature are related with fiberizing temperature range,
It is related with basaltic chemical component and mineralogical composition.
Summary of the invention
The technical problem to be solved by the present invention is in view of the above shortcomings of the prior art, and provide it is a kind of improve it is continuous profound
The continuous basalt fiber production technology of military rock tensile strength of fiber.
In order to solve the above technical problems, the present invention adopts the following technical scheme:
A kind of continuous basalt fiber production technology, which is characterized in that including burden process, melting process and fiberizing
Process, the sorting process configurations mixture, mixture is by high SiO2The basalt of content and low SiO2The basalt of content presses matter
Amount percentage 10-60:40-90 is mixed, high SiO2The basalt of content and low SiO2The basalt of content be silicon saturation or
Supersaturated rock.
High SiO2The basalt SiO of content2Content be 55-75%, low SiO2The basalt SiO of content2Content be
40-55%.
The high SiO2The basalt of content is andesite, trachyandesite, dacite, toscanite or rhyolite, low SiO2
The basalt of content is basalt, basalt andesite, trachybasalt or Black Warrior trachyandesite.
High SiO in mixture2Rock Species in the basalt of content are one kind, low SiO in mixture2The Black Warrior of content
Rock Species in rock are one or more.
The essential mineral group of the mixture is divided into quartz, orthoclase, plagioclase or pyroxene, wherein quartz, orthoclase or
One of plagioclase or more than one content are higher than the single basalt before mixing.
The essential mineral component of the mixture expire weight percent foot: plagioclase: 45%-60%, quartz: > 10% or
Orthoclase > 10%.
The present invention is not in the case where changing original technique and device, by the method for ore mixing, in low SiO2Content
Basalt in introduce high SiO2The basalt of content forms basalt combination material.Compared with single basalt, basalt combination
The chemical component of material and the variation of mineral constituent improve the tensile strength of basalt fibre, and the optimization that performance is melted in basalt promotees
Into homogenizing for basalt glass, to improve the tensile strength of basalt fibre.
The glass viscosity of continuous basalt fiber of the present invention combination material, viscosity at 1450 DEG C is 50-350dPa ﹒ s, and
Viscosity is 200-2000dPa ﹒ s at 1300 DEG C.
Crystallization temperature of the crystallization temperature lower than single basalt glass of continuous basalt fiber combination material of the present invention, combination
The fiberizing temperature range of material basalt glass is wider than the fiberizing temperature range of single basalt glass.Performance is melted
Optimization, is conducive to homogenizing for Basalt melt, is conducive to the tensile strength for improving continuous basalt fiber.
The utility model has the advantages that
(1) pervious technology is to improve continuous basalt fiber by adding one or more oxides into basalt
A certain performance, this technology increases the difficulty that homogenizes of Basalt melt, while bringing more bubbles into and entering melt, makes
Wire-drawing operation is obtained to have some setbacks.And in the present invention, it is mixed and is homogenized by two or more basalt, both remained the pure of raw material
Natural sex, and do not change original production process route and equipment, moreover it is possible to reduce production cost.
(2) in the present invention, as SiO in basalt combination material2Content is greater than single basaltic SiO2When content, basalt
The tensile strength of combination material fiber is higher than the tensile strength of single basalt fibre.What is more, when in basalt combination material
SiO2Content is close to or smaller than single basaltic SiO2When content, the tensile strength of basalt combination material fiber is still above list
The tensile strength of one basalt fibre, this is because mixing becomes the type and content of basaltic essential mineral component
Change (quartz, orthoclase, plagioclase content increase, the reduction of pyroxene content), thus to the tensile strength of continuous basalt fiber
It improves and generates Beneficial Effect.
(3) quartz, orthoclase, the silicate that plagioclase is rack-like structure, content increases so that rack-like knot in mineral constituent
The increase of the silicate mineral of structure, so that the polyhedron number into the rack-like structure in basalt glass melt increases, thus
The tightness of glass network structure connection is improved, and then improves the tensile strength of continuous basalt fiber.
(4) present invention optimizes basaltic melting technology while improving the tensile strength of continuous basalt fiber
And fiber-forming process, the homogenieity of Basalt melt is improved, the production technology of continuous basalt fiber is greatly optimized.
