Abstract
The invention relates to super thin strengthened microcrystalline fiber made from molten slag of power station and preparation methods and wide applications thereof in the industry. The microcrystalline fiber can be added to road pavement materials, engineering plastic, rubber, cement, and paper pulp to produce remarkable engineering performances.
Description
Technical field
The present invention relates to a kind of microcrystalline cellulose and its production and use, ultra-fine toughness reinforcing microcrystalline cellulose of producing more specifically to the slag that utilizes ignition power power station liquid molten and its production and use.
Background technology
Common glass fibre is crisp but also lacking toughness not only, is unsuitable for adding to such as playing the framework effect in the material structure and the intensity and the amount of deflection of strongthener in paper pulp, plastics, rubber, cement, coating or the like the Industrial materials.
Microcrystalline cellulose of the present invention has superfine diameter (3-30 micron) and stronger toughness, has overcome the deficiency on the glass fiber material performance, if add the intensity and the water resistance that can strengthen paper product in the paper pulp to; If add in the plastics, intensity and amount of deflection that can the reinforced plastics member make it not easy fracture and distortion; If add in the rubber, can improve the intensity and the wear resistance of rubber item; If add in the highway pavement material, can increase the ductility on road surface and resist the pavement cracking that variation of ambient temperature causes; If add in the cement material, intensity that can the refinforced cement goods and prevent permeability performance.
Summary of the invention
The preparation method of microcrystalline cellulose directly introduces special resistant to elevated temperatures stirring with about 1500 ℃ the molten slag in fuel-burning power plant to hold stove, this rabbling roaster is to be formed by fire-resistant brick system, cylindrical or have an identical rectangular cross section rectangle, be 30 ° to 60 ° angles of inclination with ground, a different shapes is wherein arranged every about half meter, the partition that does not wait highly, at the highest point of this stove at two inlets, one is the inlet of slag fused, another inlet is the inlet of tenderizer, slag fused from top to bottom process of flowing just tenderizer mix the process that stirs with slag fused.Place a rotary whipping appts in the bottom exit of aforementioned rabbling roaster, this device is cylindrical, below tapered, a discharge port is arranged in the bottom.Rotary whipping appts below the liquid material inflow that the effusive slag fused of the rabbling roaster of front was mixed with tenderizer makes it to stir fully and mix by rotation.Settle a general spinning machine in the nethermost outlet of revolving stirrer, the fused material is reeled off raw silk from cocoons, 3 to 30 microns of the diameters of this filament, this product is exactly a microcrystalline cellulose.

Embodiment
Explain below in conjunction with 1 pair of microcrystalline cellulose manufacturing process of Figure of description, the slag in fused power station flows into the rabbling roaster 3 that has from agitating function from hopper 1, the temperature of the slag that flows into has 1500 to 1600 ℃, tenderizer flows into from rabbling roaster 3 from hopper 2, tenderizer by calcium hydroxide and magnesiumcarbonate form its ratio be 20: 1 to 10 to 1, institute's addition is 25% to 35% of a slag weight.Rabbling roaster is built into by refractory brick, 6 meters to 8 meters of its length, and body of heater becomes 30-60 ° of angle with the level ground.A dividing plate is arranged every about half meter in burner hearth, see figure median septum 4 and dividing plate 5, this dividing plate is arranged regularly by one high and one low, maybe can be that height is arranged brokenly, and the upper surface of this dividing plate is 30 ° to 60 ° inclinations, specifically sees Fig. 8 and Fig. 9.The slag that its objective is the fused power station is in rabbling roaster from front to back in the process of flowing, because the ramp effect of dividing plate makes fluid produce rotation, thereby slag fused is mixed automatically with tenderizer.Fully stir the back from discharge port 6 inflow spinning machines 7 at slag and tenderizer, this spinning machine is the general-purpose industrial spinning machine, for example the spinning machine of wQ---100 model.The compound that temperature is reduced to 1200 to 1300 ℃ in spinning machine reels off raw silk from cocoons, the microcrystalline cellulose of extracting out can be long, can as required it be cut into needed length later on,, can extract 3 microns to 30 microns thick microcrystalline celluloses out according to adjustment to spinning machine.
Fig. 2 is the sectional view with rabbling roaster of square-section, is rectangle perpendicular to the section of the rabbling roaster of slag flow direction, and Fig. 2 is the sectional view along slag flow direction rabbling roaster, and it shows the arrangement and the structure of dividing plate wherein.Do not make the slag fused alluvial in order to help flowing of slag,, dividing plate is made as shown in FIG. the cambered surface with fillet R in the one side of separator face towards the mobile slag.
The section that Fig. 3 is perpendicular to the rabbling roaster of slag flow direction is the sectional view of the cylindrical rabbling roaster of circle.In order to reduce the furnace wall molten slag mobile is hindered, body of heater is made cylindrical, help molten slag and flow.Because section of burner hearth is rounded, so partition shape wherein also has suitable variation.Same separator face is made dividing plate the cambered surface with fillet R towards the one side of mobile slag.Dividing plate is wherein arranged regularly by one high and one low, maybe can be that height is arranged brokenly.Anyway arrange, its purpose is wanted slag fused to have in process of flowing to roll exactly, is beneficial to mixing of slag and tenderizer.
Fig. 4 is rotary rabbling roaster, the opening for feed of 1 expression fusion plant slag wherein, the 2nd, the opening for feed of tenderizer, the 3rd, furnace wall, the 4th, body of heater, the 5th, discharge port.Motor rotates by belt or geartransmission driven rotary formula rabbling roaster, from the effusive material that mixes of discharge port, is transported to spinning machine and reels off raw silk from cocoons.
Certainly, shown in Figure 1 from rabbling roaster, can unite use with rotary rabbling roaster shown in Figure 4, flow into rotary rabbling roaster from the effusive compound of rabbling roaster, certainly, just do not need to have carried tenderizer toward this rotary rabbling roaster again, just can remove the tenderizer opening for feed yet.Purpose is more fully slag to be mixed with tenderizer by rotation, and well-mixed raw material is sent to spinning machine and reels off raw silk from cocoons.
As required, can extract the microcrystalline cellulose of different thicknesses out,, cut as required then and be cut into needed length.Be applied to different fields respectively.
1. microcrystalline cellulose can be added in the rubber in the ratio of total amount 5% to 50%,, improve the rigidity of goods simultaneously to increase the wear resisting property and the tensile property (being toughness) of rubber item.
2. microcrystalline cellulose can be added in the plastics in the ratio of total amount 5% to 30%,, improve the intensity and the toughness of goods simultaneously to increase the wear resisting property and the tensile property (being toughness) of plastics.
