Abstract
The invention relates to a method for preparing a glass wool, specifically relates to a formulation for manufacturing a glass wool with silicon-manganese steel slag as a raw material and the preparation method of the glass wool, belonging to the field of a glass wool heat insulating material. The glass wool is prepared by using a fused centrifugal method and taking silicon-manganese steel slag and other powder materials as raw materials; the method for preparing the glass wool is simple in process. The total amount of the acid-pickling boron slag and the silicon-manganese steel slag in the formulation provided by the invention is up to about 50%, so that the industrial waste is adequately utilized and the raw material cost is effectively reduced. The glass wool manufactured by the invention has excellent physical and chemical performances, and also has an excellent heat insulating effect. The product manufactured by the invention can be manufactured into all kinds of pipes, blankets and plates, and can be widely applied to insulating heat for the buildings, chemical apparatuses and pipelines.
Description
Technical field
The present invention relates to a kind of preparation method of glass wool, specifically establish the prescription and the preparation method that relate to the manufacturing glass wool take the silicomanganese slag as raw material, it belongs to the glass fibre cotton field of heat insulating materials.
Background technology
The glass wool goods are owing to the heat insulating etc. that has good thermal and insulating performance, uninflammability and weather resistance and be widely used in building heat preservation, freezer and refrigerating plant insulation, petroleum and chemical industry equipment and pipeline.The glass wool goods are received increasing concern owing to having the not available advantageous properties of polymer lagging material such as urethane and benzene plate.Usually glass wool production is with quartz sand (or ground silica), feldspar, and Wingdale, rhombspar, borax, soda ash and glass cullet are main raw material, through high temperature melting be centrifuged into fine-fibered, form through applying glue, collection cotton and curing again.Owing to having used the higher borax of price in the raw material, having made the cost of glass wool goods relatively high.
Blast-furnace slag, slag, flyash equal industrial residue generally all contain SiO
2, Al
2O
3, Fe
2O
3, CaO, the oxide compounds such as MgO can be used for glassmaking.But the research and the operation that utilize the silicomanganese slag to decide to want the raw material production glass wool there is not yet report.
Summary of the invention
The object of the present invention is to provide a kind of is prescription and the preparation method that main raw material prepares glass wool with trade waste silicomanganese slag.
To achieve these goals, technical scheme of the present invention is: be raw material with silicomanganese slag, glass cullet and other powder, its quality per distribution ratio is:
Silicomanganese slag 20～40
Glass cullet 30～50
Soda ash 5～20
Ground silica 0 ~ 10
Boron magnesium slag 0 ~ 10
Borax 0～5
Reductive agent 1 ~ 2
Used reductive agent is carbon dust or coal dust, and the purpose that adds reductive agent is for S
6+Be reduced into S
2-, SO when avoiding high temperature
2Effusion pollutes.
Described make take the silicomanganese slag as raw material the glass wool step of preparation process as:
1) batching: the silicomanganese slag is pulverized with pair roller, crossed 40 mesh sieves;
2) mix: adopt mechanical mixer to mix in silicomanganese slag and other powder admixtion; The glass cullet that with granularity are again 30 ~ 40mm are sneaked in the material.
3) found: glass is founded in the heat accumulating type end port furnace, 1000 ~ 1100 ℃ of feed temperatures, 1380 ~ 1400 ℃ of glass melting temperatures.
4) be shaped: 1000 ~ 1050 ℃ of tear drop temperature, 950 ~ 1050 ℃ of spinning head temperature.Spinning head rotating speed 2800 ~ 3500 turns, stretching wind pressure 0.03 ~ 0.05Mpa, the cotton wind pressure 0.015 ~ 0.020Mpa of cloth.
5) the applying glue collection is cotton.
6) solidify: 180 ~ 200 ℃ of lower curing in the net belt type curing oven.
7) cut out dress.
