<Activated carbon>

Charcoal is a Korean word meaning "fresh force". It is a solid product that is produced when the wood is cut off by heating the air supply or heated with very little air. The char is adsorbed and deodorized due to the porous structure of the charcoal, far-infrared emission and anion generation. It is widely known that it is effective in controlling humidity, condensation, preventing corruption, and insect repellent.

When charcoal is heated in the air, the water in the wood is first removed, and then carbon, oxygen, and hydrogen in the wood are converted into carbon dioxide and water by volatilization, and volatilized, and only a very small amount of ash is burned. Will remain. Just burn the wood to ashes. In other words, charcoal is carbonized by extracting gas from wood as heat and is also called charcoal. As a material, hard wood is generally used. In Korea, oaks (brown oak, oyster oak, Oak, row oak, etc.) are mainly used.

Activated carbon is a product that is processed by chemical and physical heat treatment of charcoal by adding water vapor of 600 ℃ ~ 900 ℃ to activate the adsorption power which is the biggest characteristic of carbonized charcoal. In order to increase the effectiveness of the charcoal, these small holes must be many, so the same process is performed once again at a temperature of 600 ℃ ~ 900 ℃, this process is called activation, most of the charcoal available on the market is carbonized Only the process, but not the activation process, because it is almost impossible to activate the char in a conventional charcoal kiln.

The inventor of the present invention uses activated carbon in order to maximize the effect of the charcoal-containing paint by repeating a number of experiments, the particle size of the powder should be 350 ± 50 mesh to maintain the porosity of the activated carbon and the coating film is damaged even under a light impact The present invention was completed by finding out what can be prevented.

<Diatomaceous earth>

Diatomaceous earth (kieselguhr) is a sediment deposited on the seabed (seawater) or reservoir (freshwater) by the harmfulness of single cell algae called diatoms (Diatoms-cell wall is composed of SiO ₂ ). It is a kind of fossil soil in which the main body of oil is piled up to form strata. As it is formed, clay, sand, volcanic ash, vegetative humus, iron hydroxide, iron sulfide, etc. are mixed and contain a lot of water.

Such diatomaceous earth is a siliceous raw material which is produced as a powder, and is a lump of dirt in which the harmfulness of diatoms is deposited. However, it is hardened by acupressure and is in a soft rock state. The chemical composition of pure diatomaceous harmful is almost SiO2 with SiO ₂ 96.16 ~ 96.80%, Al ₂ O ₃ + Fe ₂ O ₃ 1. 20 ~ 1.80%, compounded water 1.92 ~ 1.98%. However, since diatomaceous earth actually produced is caused by the accumulation of the harmfulness of diatoms at the bottom of the sea or the bottom of the lake, the chemical composition varies according to the type and amount of impurities mixed at this time, and the physical properties vary according to the type of diatomaceous earth. do.

Diatomaceous earth contains a variety of contaminants, the most common of which are organic matter, sand, and iron oxide. The organic substance can be removed by calcination, and the sand can be removed by iron chloride, and the iron oxide can be removed by iron chloride by mixing with salt and calcining at 700 to 800 ° C. Fossil diatoms are about the size of a micron and can only be confirmed by a hundred-fold magnification under a microscope. Good diatomaceous earth is very light, soft, and very porous, so porous that it can absorb up to five times its volume. The structure is a collection of porous cells such as circular, needle and semicircular. The material properties of diatomaceous earth vary depending on the type and shape of the diatomaceous earth, but the only characteristic is that there are a myriad of gaps in the cell of the diatomaceous earth, which can filter out any impurity particles. Diatomaceous earth has various characteristics due to such a porous and thus has various uses. In terms of the heating properties of diatomaceous earth, the specific gravity is generally about 0.5 to 0.7 below 700 ° C, but is about 1.4 when heated to 1100 ° C to 1400 ° C, and is about 2.2 when heated to 1400 ° C to 1600 ° C, compared to calcination at 700 ° C. The volume is about one quarter. And shrinkage by heating increases in proportion to temperature.

The best ratio of diatomaceous earth is 2.05 ~ 2.15, the specific gravity is 0.2 ~ 0.3, and the purity is a little less 0.3 ~ 0.8. The volume porosity is 77-80%, which is 6-8 times that of ordinary clay calcined at low temperatures. The permeability is 0.0957 ml / cm 2 in the 1 cm thick layer, the thermal conductivity is 0.00013 to 0.00018 gr · cal / cm 2 / sec / ° C. at 100 ° C. to 900 ° C., and the specific heat is about 0.25.

Diatomaceous earth is generally almost amorphous, but heating to 1000 ~ 1600 ℃ relatively easily cristobalite (hardness-6.5, specific gravity-2.27, streak color-white) or tridymite (hardness-6.7-7.0, specific gravity- 2.28-2.33, streaky-white). The chemical composition of diatomaceous earth is made of high purity products with 99.5wt% SiO ₂ (silicon dioxide), and its uses and characteristics are as follows.

1) As an inorganic chemical in the form of sediment of endless diatom, it is an environmentally friendly substance that is harmless to human body.

2) It is composed of fine microporous cells, and it is used as a heat insulating material, moisturizing material, heat insulating material, filtration promoting material, deodorizing purifier, and sound absorbing material by using small density, heat insulation, fire resistance, and chemical resistance.

3) It is a very small cell of diatom, which prevents the growth of mold, mites, cockroaches and pests, and it is effective for sensitive constitutions such as bronchitis, atopic dermatitis and allergy when applied to indoor architecture. It enhances exercise and releases waste accumulated in the body to maintain the health of the body.

4) As the color of streaks is white, the appearance of aesthetics and textures are varied with the use of inorganic pigments that are harmless to the human body and various roller techniques.

<Natural plant extracts>

It is the phytoncide that regards the forests with cool forest scent as the best sanctuary regardless of east and west gold. Phytoncide is a generic term for the antimicrobial substances produced by plants, meaning "phyton" and "kill". Phytoncidran, a compound of "cided" (created by the Russian-born US bacteriologist Waxman, who won the Nobel Prize in Medicine in 1952), is a cool forest fragrance from trees and streptococci, staphylococci, and diphtheria Volatile substance that kills microorganisms.

All plants have antimicrobial properties, and essential oils, the main components of natural plant extracts, are mainly terpenes and monoterpenes, camphor, citral, sesqui It consists of dozens of substances such as terpenes, diterpenes, triterpenes, mentol and geraniol, beta-selinene, beta-citral and camphene. Essential oils are neutralized by biomass, causing changes in the molecular structure of odorous substances to decompose and remove odorous substances.

In other words, the plant extract is to remove the odor by the following reaction.

〈Removal of Sulfur Compounds〉
