KR20000072291A - A preparation method of Ascon filler used by industrial waste - Google Patents

Abstract

PURPOSE: A manufacturing method of ascon filler using waste instead of limestone used in a conventional method is provided, which reduces manufacturing cost, improves abrasion resistance and heat resistance. CONSTITUTION: The manufacturing method of ascon filler using waste comprises the steps of: gathering wastes such as steel-making dust, waste gypsum and fly-ash; storing in silo; mixing steel-making dust, waste gypsum with fly-ash in a ratio of 6:2:2, 5:2:3 and 6:1:3; delivering produced ascon filler to products silo; manufacturing ascon.

Description

A preparation method of Ascon filler used by industrial waste}

The content of this patent is a technology for producing ascon filling material using waste generated in the workplace.

Currently, ascon filling material is used for the powder of mineral materials such as limestone powder, portant cement, slaked lime. In addition, the material used as the filling material is KSL 3501, whose quality is prescribed.

(Table 1 granularity)

-1.0% or less of water content

(Table 2 Other Regulations)

Currently, steelmaking dust has been recognized for its usefulness as a filling material for asphalt concrete under special 1994-0012781, and it has been put into practical use in the case of waste gypsum. It refers to the sediment generated by adding limestone to neutralize the waste. It is classified as general waste in the workplace, not designated waste under the Waste Management Act, and is recycled as raw material for cement and gypsum board, aggregate for aggregate, and brick material.

The combustion material refers to Fly-Ash, which is collected by the electric dust collector in the exhaust gas burning the bituminous coal and is currently being recycled as a ready mixed concrete, concrete admixture or cement additive. However, the government encourages the recycling of resources as designated by-products along with steel slag and construction wastes under the Promotion of Recycling of Resources Act. However, the amount of generation is increasing year by year, and about 1 million tons of combustion materials are generated. The remaining part is processed by simple landfill, so the environmental pollution is serious and the recycling plan is urgently needed.

Also, incineration ash is a material produced by burning paper sludge produced at the papermaking process by high temperature, and the ash may contain a large amount of cl- component, which makes it difficult to recycle. However, there is a problem inherent in the fundamental recycling method.

As such, the ratio of the composition of steelmaking dust: waste plaster: burned material to the total amount ratio is 6: 2: 2, 5: 2: 3, 6: 1: 3 using mechanical mixing equipment using steelmaking dust, waste gypsum and combustion materials. It is intended to be recycled as ascon packaging material by mixing.

Figure 1 is a process for producing ascon fillers according to the present patent contents

The composition of the present invention is a step that each component is generated in the workplace and collected in the cyclo and fund site, the step of transferring into the mixing facility, the step of storing in the storage cycle in the mixing facility, mixing by each component ratio, mixed production It consists of transferring the filled fillers to the product cycle, transferring and supplying the commercialized fillers to the ascon factory, and producing the ascons by using the fillers, and recycling the waste resources into chemically and physically good quality ascon fillers. Will be.

The effects of the present invention are as follows.

First, the landfilled or disposed of wastes are used as ascon fillers, which contributes to the recycling of wastes. The benefits of lowering production costs, wear resistance, acid resistance and heat resistance are expected to improve.

Third, there is an advantage of reducing the natural damage and the depletion of resources due to the production of limestone powder by replacing the existing limestone powder.
