Abstract
A method of industrial filler material is made using chemical sludge, belong to environmental chemical engineering, technical field of sludge disposal, the processing application pollution on the environment that can solve the problems, such as chemical sludge, includes the following steps: chemical sludge carrying out mud-water separation, thickening；Chemical sludge after thickening is dried to the moisture requirement for meeting industrial filler material；Chemical sludge after drying is crushed, is classified, the powder for meeting granularity requirements is obtained, surface is carried out to the powder after crushing and classification using coupling agent or surface modifier and is modified, industrial filler material is obtained.The present invention had not only solved the problem of environmental pollution of chemical sludge, but also provided a kind of industrial filler material of the industries such as rubber, plastics, building materials, daily-use chemical industry, in addition simple process and easily operated, energy conservation and environmental protection.
Description
Technical field
The invention belongs to environmental chemical engineerings, technical field of sludge disposal, and in particular to a kind of to make industry using chemical sludge
The method of filler material.
Background technique
In industrial processes, various industrial wastewaters are often generated, the processing of these industrial wastewater needs reaches
It could be discharged after mark, during processing, the precipitation method are one of widely applied methods to industrial wastewater, can generate a large amount of chemistry
Sludge.These chemical sludges often complicated component, if can be caused very to ecological environment and human health without effectively disposing
Big harm.Chemical sludge there is no effective method of disposal at present, substantially using construction material is prepared after desiccation, such as brick or building block
Deng or landfill disposal.Preparing construction material using sludge is a kind of preferable method of disposal, but due to chemical sludge ingredient
Complexity, not all chemical sludge are suitable for preparing brick or building block, such as when containing a large amount of carbonate in sludge, meeting
Cause the caking property of raw material to be deteriorated, increases the difficulty of brickmaking or building block.And landfill disposal can not only occupy valuable land resource,
But also the secondary pollution easy to form to environment.
Summary of the invention
The present invention provides a kind of using chemical sludge aiming at the problem that processing application of chemical sludge pollutes the environment
The method for making industrial filler material.
The present invention adopts the following technical scheme:
A method of industrial filler material being made using chemical sludge, is included the following steps:
Chemical sludge is carried out mud-water separation, thickening, the chemical sludge after obtaining thickening by the first step；
Chemical sludge after thickening is dried to the moisture requirement for meeting industrial filler material, obtains drying by second step
Chemical sludge afterwards；
Chemical sludge after drying is crushed, is classified by third step, the powder for meeting granularity requirements is obtained, using idol
It is modified to the powder progress surface after crushing and classification to join agent or surface modifier, obtains industrial filler material.
Mud-water separation described in the first step uses filter or centrifuge.
Drying means described in second step include in drying equipment convection drying or after natural drying again using drying set
It is standby to be dried.
Coupling agent described in third step includes silane coupling agent, titanate coupling agent, aluminate coupling agent, phosphate coupling
Any one in agent and boric acid ester coupler；The surface modifier includes fatty acid salt surface modifier or quaternary ammonium salts
Surface modifier.
Beneficial effects of the present invention are as follows:
A kind of production technology that can convert harmful chemical sludge to advantageous industrial filler material may be implemented in the present invention, both
It solves the problem of environmental pollution of chemical sludge, and provides a kind of industry of the industries such as rubber, plastics, building materials, daily-use chemical industry
Filler material, in addition simple process and easily operated, energy conservation and environmental protection.
Specific embodiment
The moisture requirement for meeting industrial filler material in the present invention refers to when industrial filler material product is respectively used to coating, rubber
When the different industries such as glue and plastics, moisture content meets applied specific industry and requires the moisture control of filler material, for originally
Field technical staff's well-known technique.
Crushing and classification in the present invention obtains the powder for meeting granularity requirements, refers to when industrial filler material is respectively applied to
When different industries, the difference of partial size is required, technology is known to the skilled person.
Embodiment 1
Using sludge caused by certain sewage treatment plant as raw material, the method for making industrial filler material using the sludge, including it is as follows
Step:
The first step, the chemical sludge that will be generated in calcium oxide with industrial wastewater, using plate and frame filter thickening；
Second step, by the chemical sludge naturally dry after thickening, using far infrared drying oven to the sludge dried at 120 DEG C
Under 4h is dried, after measured moisture content be 0.3%；
Third step crushes the chemical sludge after drying with high speed disintegrator, the standard for being 0.045mm using screen size
It is sieved, obtains 325 mesh powders, be added in Xiang Shangshu powder and account for stearic acid of the powder quality than 1%, stirred at 85 DEG C
15min progress surface is mixed to be modified to get industrial filler material product is arrived.
Above-mentioned gained industry filler material is replaced into powdered whiting, is added in PVC plastic and makes composite board, formula is such as
Under: PVC:100 parts, industrial filler material: 200 parts, asbestos: 80 parts, stabilizer: 3 parts, plasticizer: 30 parts.Made composite plate
Material sample fracture tensile strength 15.2MPa, elongation at break 292%, compressive resistance 10.5MPa.
Above-mentioned industrial filler material is added in PP plastics and makes composite board, additive amount 50%, made sample breaks
Split tensile strength 16.3MPa, elongation at break 356%, compressive resistance 9.7MPa.
