Abstract

A method for producing water-adsorbable silicic porous body is provided to apply the water-adsorbable silicic porous body to silicic or organic manure, water-purifying agent, microorganism-culturing agent, water culture agent, and deodorizing agent. A water-adsorbable silicic porous body is produced by mixing 50-80 wt% of natural mineral materials and 20-50 wt% of lime, swelling the mixed matter of natural mineral materials and lime to have a volume of 5-7 times through a foaming process using vegetable and animal foaming agents, and performing a drying process and a hardening process on the swollen matter. The natural mineral materials are selected from silicate minerals consisting of elvan, biotite, pegmatite, granite, quartz, and feldspar.

Description

The water absorption silicic acid matter numerous hole body production techniques for which natural mineral matter was used}

The present invention relates to a method for producing a water-absorbing siliceous porous body using a natural mineral, in particular, a water absorption ratio appropriate to the intended use by using a natural mineral (macbanite, biotite, maestro, granite, quartz, feldspar, etc.) The present invention relates to a method for producing a water-absorbing siliceous porous body using natural minerals, which can be used for siliceous fertilizer, water purification (red tide, green algae remover), microbial culture, hydroponic cultivation, and deodorant.

The livestock manure treatment in 2006 shows a total production of 45 million tons, marine emissions of 3 million tons, and the 2012 ban on marine discharges.

Livestock manure disposal measures, which have been wasting more than trillions of dollars over decades, have not yet found their core.

With no clear solutions yet, the livestock sector is under pressure to open up the market to achieve international competitiveness such as the FTA along with international environmental issues such as the London Convention.

In addition, according to the Ministry of Environment, the main cause of groundwater water pollution is serious contamination of microorganisms and nitrate nitrogen, mainly due to manure and livestock waste water nitrate fertilizer (chemical fertilizer).

In addition, if the livestock manure that is generated when the cattle are collectively discharged as it is, it seriously pollutes the water and soil.

Recently, livestock wastewater treatment was applied to the bottom of the barn using sawdust to absorb manure and remove odor.

However, sawdust has a problem that the water absorption rate is low and the large amount should be laid and the fertilization period takes at least one year, and the supply and demand is absolutely insufficient and the total amount depends on imports.

On the other hand, food wastewater is being discharged in large quantities every day, and until now, the wastewater has been treated by ocean dumping method. However, since July 1, 2007, only wastewater having a water content of 95% or more can be dumped. Is difficult.

In addition, since the food itself contains a large amount of salt, there are many difficulties in producing manure and compost.

Therefore, the present invention was devised to solve the problems described above, by using a natural mineral (egban rock, biotite, feldspar, silicate minerals such as granite, quartz, feldspar) to treat livestock manure and remaining foods It is an object of the present invention to provide a method for preparing a water-absorbing siliceous porous body using natural minerals, which can be used for siliceous fertilizer, water purification (red tide, green algae remover), microbial culture, hydroponic cultivation, and deodorization.

Water absorbing siliceous porous body manufacturing method using a natural mineral according to the present invention for achieving the above object is to crush the natural mineral and lime to 300 mesh or more to mix the natural mineral 50 to 80% by weight and lime 20 to 50% by weight, Plant and animal foaming agent is added to expand the volume of natural minerals and lime by 5 to 7 times, characterized in that the foaming, drying, firing is produced.

Water-absorbing siliceous porous body manufacturing method using a natural mineral according to the present invention made of a configuration as described above according to the intended use by using natural minerals (macbanite, biotite, maestro, granite, quartz, feldspar, etc.) There is an advantage that can be used in siliceous and organic fertilizer, water purification (red tide, green algae remover), microbial culture, hydroponic cultivation, deodorant having a proper water absorption.

Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.

1 is a process chart showing a water-absorbing siliceous porous body manufacturing process using a natural mineral according to the present invention.

As shown in this figure, the method for producing water-absorbing siliceous porous body using the natural mineral according to the present invention is to crush the natural mineral and lime to 300 mesh or more to mix 50 to 80% by weight of the natural mineral and 20 to 50% by weight of lime It is prepared by expanding the volume of natural mineral and lime by 5 ~ 7 times by adding vegetable and animal foaming agent to foaming, drying and firing.

Here, the natural mineral is selectively used any one of silicate minerals consisting of elvan, biotite, macrorite, granite, quartz, feldspar.

Therefore, the water-absorbing siliceous porous body using the natural mineral according to the present invention is mostly composed of fine bubbles (humidity control ability), it is possible to produce a water-absorbing siliceous porous body of 5 to 7㎥ of the raw material 1㎥.

The manufacturing process of water absorbing siliceous porous body is environmentally friendly.

When curing autoclave, the optimum temperature is 170 ~ 200 ℃, the most preferable temperature is 180 ℃, steam curing time is 2-3 hours, and steam used in steam curing process is reused several times. The curing method does not generate any harmful substances that are harmful to air, water and soil.

The following is a lightweight foaming agent cured by high pressure sterilizer. The main raw materials are natural minerals (silicates composed of barley, biotite, macrorite, granite, quartz and feldspar) and lime containing a lot of silica (SiO ₂ ).

Mix the blowing agent and stabilizer with natural minerals (macrite stone, biotite, macrorite, granite, quartz, feldspar silicate), put them in the formwork, expand and expand the foam, and remove it when it solidifies into a cake shape. Heal at 10 atm.

The specific gravity is 0.7-0.9, and it is a siliceous porous body having a volume deformation of porous (more than 80% of porosity) when it is absorbed and dried so that it is excellent in microbial culture or water absorption and silicon oxide (SiO ₂ ) is 50% or more.

In addition, since the water-absorbing siliceous porous body uses natural minerals (silicate minerals such as elvan, biotite, macrorite, granite, quartz, feldspar), it is inexpensive and has no problem in moisture, and the composting period is about 7 to 15 days.
