Method.
Technical background
With the reinforcement of environmental consciousness, coal fuel brings flyash discharge capacity serious harm environment, combustion
The flyash total amount that coal steam power plant is discharged every year increases year by year, the development of the national economy and ecology to China
Environment causes huge pressure.Country builds with Regional Recycling Economy industry to following total utilization of PCA and carries
New demand for development is gone out.Think the potentiality of comprehensive utilization flyash high value added utilization, be real synthesis
Using the developing direction with recycling economy.China is building work, building materials, water by developmental research, flyash
Li Deng all departments are widely used.The approach of total utilization of PCA with from past roadbed, embankment,
Outside the application of the aspects such as concrete admixture, soil remediation, develop into current in cement raw material, cement
Mixing material, Large Hydro-Junction engineering, pump concrete, mass concrete product, senior filler etc.
Advanced utilization ways.Flyash is mainly used to production pulverized fuel ash cement, flyash brick, flyash silicic acid
Salt building block, powder ash air-entrained concrete and other construction materials, also act as agricultural fertilizer and soil improvement
Agent, reclaims the raw material of industry and makees environmentally conscious materialses.The present invention is according to flyash in coal dust firing and discharge process
The composite construction mixture of the crystal, vitreum and a small amount of unburned charcoal composition of middle formation.Propose a kind of new
Glass fibre and preparation method thereof, to expand the utilization field of flyash.
The present invention, by experiment for many years, improves calcium hydroxide and magnesium sulfate ratio using flyash, can
Alkali-resistant glass fibre is obtained, make the utilization of flyash has a new development field again.
The content of the invention
It is an object of the invention to improve calcium hydroxide and magnesium sulfate ratio using flyash, alkali-proof glass is obtained
Fiber, had both solved the problems, such as fine coal ash fouling environment, and the quality of glass fiber product is improve again.
To achieve these goals, processing step of the present invention is as follows：
First, composition of raw materials quality score：
2nd, technological process and technical parameter
1st, flyash, calcium hydroxide, magnesium sulfate, borax, steel fibre are crushed to 320~480 mesh, according to matter
Amount ratio, adds in reactor, under agitation, is sufficiently mixed uniform；
2nd, by well mixed feeding melting furnace, melted under 1200 DEG C of high temperature, cool down to obtain chips of glass body；
3rd, kiln temperature starts to feed intake at 1600 DEG C, depending on rate of feeding is according to chips of glass body molten state in kiln, when logical
Road temperature reaches 1200~1500 DEG C, and metal level reaches design height, and glass quality is qualified, is transferred to wire drawing
Operation.
4th, using 69-1 type bitubular automatic can_doffing wire drawing machinees, temperature control, level control, bushing are controlled to ripe skill
Art, there is wire drawing machine Automated condtrol.
5th, wire drawing finished product can alkali resistance, a diameter of 10-20 microns, tensile strength is 16-19MPa, elasticity
Coefficient is 600-70MPa, it is adaptable to manufacture pressure vessels for the chemical industry and reinforcing concrete.
The beneficial effects of the present invention are：
1st, inventive formulation is simple, and processing technology is mature technology, has expanded the value of exploiting and utilizing of flyash.
The industrial products of high added value are processed using flyash,
2nd, the present invention meets national total utilization of PCA and Regional Recycling Economy industry builds demand for development, right
In protecting ecology, resource reutilization is a promising project.
3rd, the present invention also relates to Materials Science and Engineering science and technology, workability, compression strength to material,
Rupture strength has the development of exploration.
Specific embodiment
Example 1, the present invention are tested using Lanzhou A Ganzhen collieries flyash, and the processing step of use is as follows：
