20 is a flow chart for preparing a degradation promoter using brown algae contained in the microcapsule layer according to the third embodiment of the present invention.

First, brown algae are washed with ethanol to remove impurities from the brown algae. Herein, the brown algae may include kelp, sea bass, sweet potato, mackerel, mackerel, rhubarb, and mackerel. In addition, the brown algae may use a single kind or two or more kinds, and when two or more types are used, the content ratio of the raw materials may be variously set according to the design of the manufacturer.

For example, kelp and sea mustard are prepared at the same weight ratio, and the prepared kelp and the seaweed are firstly washed, and the impurities attached to the kelp and the seaweed are firstly washed.

In addition, the kelp and the seaweed in which the first impurities are removed are washed with ethanol to remove impurities remaining in the kelp and the seaweed (S2010).

Thereafter, the brown algae from which the impurities are removed are dried so that the moisture content is 20% or less (for example, the moisture content is 15% to 20%).

At this time, the drying method may be dried through a dryer (not shown) or naturally dried at room temperature.

For example, the brown algae containing the kelp and the seaweed from which the impurities have been removed are dried through the dryer to a moisture content of the brown algae of 20% or less (S2020).

Thereafter, the dried brown algae and an aqueous solution of sodium hydroxide (for example, a 1.5 wt% aqueous solution of sodium hydroxide) are mixed at a weight ratio of 1: 0.7 to prepare a mixture.

Further, the brown algae mixed with the sodium hydroxide aqueous solution through a heater (not shown) is boiled (or heated) at a temperature ranging from 180 ° C to 220 ° C (generally 200 ° C) for 50 minutes to 70 minutes ).

For example, 35 kg of the aqueous sodium hydroxide solution is mixed with 50 kg of the dried brown algae, and the aqueous solution of sodium hydroxide mixed with the brown algae is boiled for 60 minutes at 180 ° C to 220 ° C by a heater (S2030).

Thereafter, the boiled mixture is centrifuged through a centrifugal separator (not shown) to remove the aqueous solution and the precipitate, and to secure (or obtain / prepare) the first residue material. At this time, the boiled mixture may be cooled at room temperature for a preset time of 1 hour to 24 hours, and the cooled mixture may be centrifuged to remove the aqueous solution and the precipitate, thereby securing the first residue material.

For example, the heated mixture is centrifuged through the centrifugal separator to remove the aqueous solution and the precipitate to secure the first residue (S2040).

Thereafter, the first residual material is filtered through a filter paper (e.g., No. 2 filter paper (Whatman plc., Kent, UK) to secure (or obtain / prepare) a second residual material .

For example, the first residual material is filtered through the filter paper to secure a second residual material (S2050).

Thereafter, the second residual material is gamma-processed through a gamma processor (not shown), and a decomposition promoter 230 using brown algae is prepared through a sterilization process.

That is, the cobalt-60 radioisotope (1.17 MeV) is irradiated to the second residual material through the gamma processor for 8 seconds to 12 seconds (generally 10 seconds) to remove the sterilized decomposition promoter 230 ).

For example, the gamma processing function of the second residual material is performed through the gamma processor to perform a sterilization treatment on the harmful groups, bacteria, and the like remaining in the second residue material, and the sterilized decomposition promoter 230 (S2060).

As described above, the embodiment of the present invention can provide an environmentally friendly pad by forming a microcapsule layer using pulp powder, superabsorbent resin and degradation accelerator using brown algae.

In addition, as described above, in the embodiment of the present invention, when the superabsorbent resin contained in the pad absorbs the liquid phase and changes to the gel state, the superabsorbent resin changed to the gel state reacts with the degradation accelerator using brown algae So as to rapidly accelerate the decomposition speed of the superabsorbent resin, thereby decomposing the superabsorbent resin into a treatable liquid state that helps to preserve the environment, not waste, thereby preventing environmental pollution and lipid contamination.
