Abstract

In the wallpaper paste experiment with addition of 0% of illite, HCHO was 0.0619 ppm in the first and 0.0659 ppm in the second, so the effect on the human body that it is possible to smell. In addition, in the experiment in which 50% of illite was added, 0.0122 ppm in the first and 0.013 ppm in the second were obtained, confirming that it was the lower limit of the HCHO measuring instrument. The basis for this result is shown in Table 1. The purpose of this study is to determine how much HCHO and TVOC emitted from wallpaper can be reduced by illite, so it was analyzed by T-Test to find out if it was statistically significant. Based on Table 11, the P value was 0.01984915296, which is less than 0.05, and thus the result was statistically significant. As a result, it was concluded that the amount of HCHO released from the wallpaper can be effectively reduced when the wallpaper paste mixed with illite is applied to the wall.

Description

The effect of indoor building materials added with illite on indoor air quality{THE EFFECTS OF ILLITE ON INDOOR AIR QUALITY}

Odor removal, Illite application.

Since the 1960s, people have been pursuing high-rise and large-scale buildings due to the urbanization phenomenon in which the population is concentrated in cities until now. With the economic growth of industrialization, people's living standards have improved, and they are interested in maintaining a healthy life not only for the purpose of living in their homes but also in the living space. However, a syndrome called Sick House Syndrome is interfering with the goal of living a healthy life for people residing in new apartments or new public institutions. This research team proposes Illite, which has been attracting attention so far, as a solution to this problem. Illite is the most important and most important clay mineral from shale or sandstone. It contains a large amount of K + and is rich in Si +, Mg 2 +, and H 2 O than similar mineral muscovite mica. Illite's scientific features include oxygen deficiency supplementation, toxic element adsorption performance, semiconductor action, human immunity enhancement, viral disease prevention, heavy metal detoxification, environmental hormone removal and liver toxicity relief, negative ion far-infrared radiation, autonomic nervous system stability, antibacterial and antibacterial Virus outbreak, normalization of pulse, prevention of cellular aging, removal of human wastes, etc. (Chang-Oh Choo, mineralogical properties of Illite and its application, 2001).

Recently, with the popularization of capsule coffee machines that can conveniently enjoy coffee beans, it was thought that a large amount of discarded coffee capsules would affect environmental pollution. Since this discarded capsule is composed of aluminum and plastic ground beans, the invention was invented to absorb odors in the house and adsorb fine dust with the separated coffee grounds by a method of separating and recycling these environmental pollutants.

Many experiments and previous papers on the change in air quality due to interior building materials have been published.

exist. In a recent paper on illite, there was a paper that evaluated the reduction of the concentration of radon gas, a first-class carcinogen, due to magnesium oxide board using anthracite.

As a result, the concentration of radon gas decreased when a certain amount of anthracite was added.

Do (Pyun Soo-jeong, Lim Hyun-woong, Lee Sang-soo, 2018, Evaluation of reduction of radon gas concentration in indoor air quality of magnesium oxide board using anthrasite). However, there are many factors that affect indoor air quality as well as building materials. Therefore, in this study, as the first experiment, after excluding other additional interiors and applying only general wallpaper and paste to a house built of ordinary wood, a wallpaper paste was produced with different illight addition rates, and this paste was used as a harmful substance in the indoor air quality. (HCHO, TVOC) I would like to conduct research on how it affects.

In the experiment of wallpaper paste with 0% of ilite added, HCHO was 0.0619ppm for the first and 0.0659ppm for the second, and the effect on the human body is enough to smell. In addition, in the experiment in which 50% of illite was added, the values of 0.0122 ppm for the first and 0.013 ppm for the second were shown, confirming that the values were the lower limit values of the HCHO meter. The rationale for this result is shown in Table 1.

It is stated. The purpose of this study is to determine how much illite reduces HCHO and TVOC emitted from remote areas, so it was analyzed by T-Test to find out whether it is statistically significant. Based on Table 11, the P value was 0.01984915296, which was less than 0.05, so the result was statistically significant. As a result, it was concluded that the amount of HCHO released from the wallpaper was effectively reduced when ilite was mixed with the wallpaper paste and applied to the wall.

Fig. 1 is an embodiment of the present invention

In the experiment of paint with 0% illite added, HCHO was 0.62 ppm for the first and 0.304 ppm for the second, and the effect on the human body is that it causes breathing disorders and irritation to the neck. Next, in the experiment with 50% of illite added, the values of 0.393ppm for the first and 0.0985ppm for the second were shown, indicating that the measurement result was significantly lower than the HCHO measurement result of the paint experiment with 0% illite added. It can be seen that breathing problems begin and you can feel the smell. The rationale for this result is given in Table 1. When viewed with the naked eye, especially in Table 7, it can be seen that the average value of the results of the two experiments is significantly different, but the T-Test was conducted to perform a little more accurate and objective analysis. As can be seen from Table 13, the P value was 0.03162096456, but it was statistically significant because it was less than 0.05. In the paint experiment with 0% illite added, TVOC was found to be 4.81mg/m 3 in the first and 2.701 mg/m 3 in the second. Next, in the wallpaper paste experiment with 50% illite added, the first 1.504mg/m 3 and the second 0.876mg/m 3 were obtained. TVOC is considered to have a clear adverse effect on health if a value of 3.0 to 25 mg/m 3 is measured in Table 2. There was a significant decrease when viewed with the naked eye, but statistically, the P value was greater than 0.05, so it was meaningless. A conclusion was made. Therefore, it was concluded that illite was not effective in reducing TVOC from paint from this experiment.
