Description

Microporous preservation activated carbon and manufacturing method of ocher board and mortar using same {Manufacturing method of activated charcoal with micro-pore, loess board and mortar using the same}

The present invention relates to a method for manufacturing activated carbon board, which is a built-in finishing material for building using activated carbon and loess, and to minimize the blockage of activated carbon micropores due to the mixture, and converts the activated carbon to the original state after a certain time. It relates to an activated carbon production method that can fully exhibit the function of.

Currently, gypsum board used in Korea occupies most of products manufactured by adding gypsum fine powder, sand and crack asbestos at a certain ratio.

Since the existing gypsum board is made of gypsum and sand, which are fast curing materials, and pulp attached to both sides of the gypsum board, it is heavy and has poor compressive strength and tensile strength, making it difficult to manage the product during construction. There are problems in terms of economics and durability. Therefore, attempts have been made to manufacture boards to which stone powder, gravel, sand, etc. have been added in order to compensate for the above disadvantages and to improve the durability, robustness, and water absorption of the product, but due to the specific gravity and characteristics of the gypsum plaster which is anhydraulicity, It has caused some problems. In other words, when excessive mixing of gravel and sand to increase the compressive strength and tensile strength, the weight is higher than the volume, there is a lot of difficulties in transportation and use, and the water absorption rate is lowered when excessively increasing the mixing ratio of the fiber to increase the tensile strength As a result, there have been many difficulties in manufacturing a finishing board that satisfies absorbent performance and simultaneously meets durability and light weight.

Therefore, the micropores of about 1 / 10000mm are distributed innumerably, and have a surface area of about 250 ~ 300㎡ (75 ~ 90 pyeong) per 1g, which removes harmful substances and odors in water and air. Research on the manufacture of activated carbon ocher board using light activated carbon and loess, excellent in water absorption, sound absorption and sound insulation, has been conducted. However, in the case of the activated carbon, despite the above advantages, the foreign matter mixed with the feature of rejecting the mixing of other foreign matters is not applied to the actual site due to the problem of solidifying the micropores of the activated carbon.

An object of the present invention is to provide a method for producing activated carbon mixed with various boards or mortar to maintain the micropores of the activated carbon for solving the problems of the gypsum board and the problem of activated carbon.

Another object of the present invention is heavy and high failure rate in the characteristics of gypsum board through the use of the activated carbon, supplementing and removing the low absorption rate and at the same time by mixing ocher, germanium ore and elvan to remove odor and prevent mold in the room To provide a light and strong building interior board manufacturing method using, ocher and gypsum.

In addition, to provide a method for producing mortar for juveniles having similar characteristics to the board made of a mixture of activated carbon, loess, germanium ore and elvan, which have the micropores having the above advantages.

The present invention classifies the main materials of activated carbon (particularly pine, oak, and bamboo), heats and carbonizes them in a kiln at a temperature of 1000 ° C to 1500 ° C, and then sorts only the carbonized activated carbon and grinds it into particles of 0.5 to 1.0 mm. Was precipitated in a solution of Dow Corning LS303 silicone, which is a food additive, in a 3: 7 mixture of water, and dried first.Then, it was formed and cured by mixing germanium ore, elvan, loess, sand, cotton yarn and gypsum plaster. To manufacture the board.

That is, in order to solve the problem that the activated carbon, which is the main material of the present invention, refuses the mixing of other foreign substances and the mixed foreign substances solidify the micropores of the activated carbon, foods to avoid filling by the foreign substances of the micropores of the pulverized activated carbon Dow Corning LS303 silicone (3) as an additive was mixed and diluted at a ratio of water (7), and then pulverized and screened activated carbon was placed in a sack and precipitated in the mixed solution for 10 to 30 minutes to dry. Dry at high heat. The reason why the activated carbon is precipitated in the mixture of Dow Corning LS303 silicon and water is to prevent the micropores of the activated carbon from filling with other foreign substances, and the other mixture filling the micropores of the activated carbon through mixing and drying the precipitated activated carbon is The above problems were solved by slowly dissolving the micropores, which are inherent in activated carbon, and additionally used a board plaster plaster for safe curing of the mixed materials. In addition, even after successful curing, the curing rate, the time required for the curing reaction, and the strength after the completion of the curing has a side effect that adversely affects the quality of the product. In other words, if the curing speed is too fast, the product manufacturing process cannot recognize the time and completeness of the product, and if the curing is too slow, the board may be shaken like thin acrylic and lose the function of the board. Therefore, in order to solve the above problems, it was possible to obtain the dual effect of increasing the strength and reducing the weight by adjusting the elasticity by mixing the clay with activated carbon and crushing and mixing the gypsum and mineral powder. In addition, fine coarse yarn was added to replace asbestos to increase cohesiveness, and cohesion was improved by attaching crack prevention nets and pulp on both sides in order to improve the firmness of the board.

In other words, the characteristic of activated carbon that has been precipitated and dried is that the micropores of activated carbon are temporarily charged and then dissolved and decomposed in the mixing process of foreign substances, so that the micropores exist as the raw materials of the activated carbon. Performance is superior to other materials. In addition, the characteristics of the activated carbon are combined with the merits of ocher and gypsum plaster, and when reacting with foreign substances, the mineral elements that convert and generate ion electrons contained in germanium ores into pure oxygen, causing decomposition, neutralization and removal. Phosphorus germanium ores were mixed, and in addition, elvan minerals were added to remove the chemical odors of various paints used for the space decoration of cement mortar finishing walls and interior buildings.

In addition, by bonding the crack prevention net, which is a mesh made of synthetic resin or natural fiber, which is not used in the manufacturing process of the existing gypsum board to both sides of the board, the durability is reduced by reducing the breakage rate during the transport and use process. The unit weight is also about 1/4 lighter than the existing gypsum board, thereby ensuring the convenience of construction.

In addition, cement, ceramic or loess added products commonly used in the field is a lot of cost and time required for drying or curing by mixing in the field, while the loess board of the present invention does not mix water The dry packing method can be used as a material for consolidation on the floor or wall at the site by drying the packaging, which can shorten the manufacturing cost and production process.

In addition, in order to prevent breakage and chipping of the processed cut surface of the activated carbon ocher board, it may be finished by treating with liquid silicon or ordinary silicon containing activated carbon. The activated carbon ocher board can be applied to various interior materials of furniture (kitchen sinks, wardrobes, shoe cabinets) using not only the interior finishing materials for construction but also the ability to block moisture and mold during the rainy season or during the rainy season.
