Abstract
The invention relates to a method for manufacturing fiber by taking coal gangue slag as raw material, which takes the coal gangue slag as main raw material, the method is characterized in that the method comprises the following steps: mixing and stirring the coal gangue slag with the softening agent, the disperser and the water and then granulating, melting by heating in sealed furnaces with high temperature, controlling the steady melt viscosity, being blown out and forming into silk after being melted by multi-holed spinnerets under pressurizing, then spraying the surface modifier, namely obtaining the super fine inorganic calcium fiber. The method has the beneficial effects that the physical property of the coal gangue slag can be accord with that of the plant fiber property, the coal gangue slag can replace the plant fiber and be used as the main raw material for making paper, the method functionally utilizes the industrial waste, which saves the consumption of log and has obvious significance in forest resource protecting, and enables the industrial waste to be an ideal energy-saving material.
Description
Technical field
The present invention relates to pulp technology for making paper, relating in particular to a kind of is the method that raw material is made fiber with the coal gangue clinker.
Background technology
The raw material of paper technology use at present generally is a large amount of vegetative fibers that come from plants such as timber that utilize, cut down timber in large quantities natural resources and existent environment of people have been caused great destruction, cause environmental pollution owing to being easy to generate a large amount of industrial wastewaters in the production process simultaneously.And the coal gangue clinker of power plant's output is directly disposed usually simultaneously, use added value and do not obtain paying attention to, and the severe contamination and the waste of resource on the one hand, and effective on the other hand resource does not obtain sufficient renovation and utilization, very unfortunate.
Summary of the invention
The purpose of this invention is to provide a kind of coal gangue clinker fiber, to replace the existing plant paper fibre that causes environmental pollution and the waste of the great forest reserves easily commonly used.。
The method that with the coal gangue clinker is raw material is made fiber of the present invention may further comprise the steps: be main raw material with the coal gangue clinker, its preparation process is: coal gangue clinker is mixed with softening agent, dispersant and water stir and granulation, heat fused in high temperature closure formula stove, the melt viscosity of control stabilization, add to depress and be emitted into silk by the fusion of porous spinnerets, spray necessary cooling agent or surface modifier subsequently, promptly obtain ultra-fine inorganic calcium fiber; Wherein raw material comprises following components in weight percentage: softening agent 2-12%, dispersant 1.2-8.6%, surface modifier 1.8-10.6%, coal gangue clinker 20-60%, water 25-35%; Wherein said softening agent is selected from hydrochloric acid, sulfuric acid, acetic acid, alkyl acid slaine one or more mixture wherein; Described dispersant is selected from wherein one or more mixture of sodium polyphosphate, algae acyl acid sodium, lauryl sodium sulfate, neopelex, oxidic polyethylene, emulsification methyl-silicone oil; Described surface modifier is selected from polyvinyl alcohol water solution, polyacrylamide solution, the modified starch aqueous solution, carboxymethyl cellulose, size emulsion one or more mixture wherein.
Beneficial effect of the present invention is: coal gangue clinker fiber physical property of the present invention reaches the equal performance of string, can substitute the important source material of string as field products such as papermaking fully; Method of the present invention is given industrial waste with the functionalization utilization, saves log and expends, and is remarkable to the meaning that protects forest resources, and is desirable energy-saving raw material; can extensively promote the use produce heat insulation, warming, insulating materials, density board; buildings such as pitch swelling fiber, packing, fields such as building materials.
