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, belonging to the field of a glass wool heat insulating material, wherein the glass wool is prepared by using a fused centrifugal method and taking the 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 lowered. The glass wool manufactured by the invention has excellent physical and chemical performances, and 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 heats for all kinds of buildings, chemical apparatuses and pipelines.
Description
Technical field
The present invention relates to a kind of preparation method of glass wool, specifically establish and relate to a kind of prescription of making 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 technique 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 pickling boron slag, 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.
The characteristics that the present invention gives prominence to are: prepare glass wool take silicomanganese slag and other powder as main raw material adopts the melting centrifuging, technique is simple.Pickling boron slag, silicomanganese slag total amount can reach about 50% among the present invention, take full advantage of trade waste, and effectively reduce expense of raw materials.Glass wool of the present invention has good physics and chemistry performance, and good heat insulating effect is arranged.Product can be made into all kinds of tubing, cotton felt and sheet material, can be widely used in the heat insulating of various buildings, chemical industry equipment and pipeline etc.
Embodiment
Making the prescription of glass wool take the silicomanganese slag as raw material, is raw material with pickling boron slag, silicomanganese slag, glass cullet and other powder, and 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.
