Description
본 발명은 아이스팩 충진제를 활용한 항균성 제습제에 관한 것으로, 더욱 상세하게는 아이스팩 충진제로 사용되고 있는 고흡수성 수지(Super Absorbent Polymer; SAP)를 가공한 후, 항균 물질로 코팅함으로써, 항균 및 제습 효과가 우수한 항균성 제습제에 관한 것이다. The present invention relates to an antibacterial dehumidifier using an ice pack filler, and more particularly, by processing a super absorbent polymer (SAP) used as an ice pack filler and then coating it with an antibacterial material, which has excellent antibacterial and dehumidifying effects. It relates to an antibacterial desiccant.
아이스팩을 냉동하여 얼음 대용으로 각종 음식물이나 수산물의 보관 및 운반시 또는 미용 등 다양한 목적으로 사용하게 된다. 이러한 아이스팩은 얼음에 비해 사용시간이 길어 그 효과가 우수하여 현재 널리 사용되고 있다.Ice packs are frozen and used as a substitute for ice for various purposes such as storage and transportation of various foods or marine products, or beauty. These ice packs have a longer use time than ice and have excellent effects, and are therefore widely used.
이러한 아이스팩은 충진제로서 종래 물을 얼려 사용하는 형태의 팩보다 장시간 냉각 상태를 지속할 수 있다는 점에서 고흡수성 수지를 많이 사용하고 있다. 최근에는 음식 배달 문화와 온라인 주문 등으로 인하여 그 수요가 크게 증가함에 따라 아이스팩 시장은 급격한 성장세를 보이고 있다. These ice packs use a lot of superabsorbent polymers as a filler in that they can maintain a cooling state for a longer period of time than conventional packs using frozen water. Recently, the ice pack market is showing rapid growth as the demand for food delivery has increased significantly due to the culture of food delivery and online ordering.
고흡수성 수지(Super Absorbent Polymer; SAP)는 자기중량의 수백 배 내지 천여 배에 이르는 물을 흡수하여 보유할 수 있는 고분자 물질로서, 물을 첨가하면 팽윤(swelling)하여 수화젤(hydrogel)을 형성하고 이 수화된 젤은 외부로부터 압력을 가해도 물을 쉽게 배출되지 않는 특징을 가지고 있다.Super Absorbent Polymer (SAP) is a polymeric material that can absorb and retain hundreds to thousands of times its own weight in water. When water is added, it swells to form a hydrogel. This hydrated gel has a feature that does not easily drain water even when pressure is applied from the outside.
그러나, 고흡수성 수지가 충진된 아이스팩은 폐기가 용이하지 못하다는 문제점이 있다. However, there is a problem in that the ice pack filled with the superabsorbent polymer is not easy to dispose of.
고흡수성 수지가 충진된 아이스팩은 가격이 저렴하고, 쉽게 구매가 가능하여흔히 쓰이지만, 대부분 일회용으로 한번 쓰고 버려진다. 그런데 따로 버릴 곳이 마땅히 없고 분리배출도 어려워 쓰레기 배출량을 증가시키고 있다. Ice packs filled with superabsorbent polymer are inexpensive and easily available, so they are commonly used, but most of them are used once and thrown away. However, there is no proper place to throw it away, and it is difficult to separate and dispose of it, increasing the amount of waste.
폐기 시, 포장재 내부에서 고흡수성 수지를 분리 배출해야 하는데, 가정이나 회사 등과 같이 별도의 특수처리 시설이 구비되어 있지 않은 곳에서 겔 상태의 고흡수성 수지를 싱크대나 하수구에 버리면, 겔 상태를 유지하려는 수지의 특성으로 수지가 배관 내벽에 유착되고, 결국 유로를 차단하는 문제점이 있다. 또한, 배관으로부터 수지가 배출된다 하더라도 초미세 플라스틱 상태로 강이나 바다로 흘러 들어가게 되어 환경에 악영향을 미치게 되며, 하수처리장으로 유입된 고흡수성 수지는 다양한 물질과 결합하여 하수처리 장비의 고장을 유발하는 문제점이 있다. 또한, 아이스팩을 소각처리한다 하더라도 겔 상태의 고흡수성 수지를 소각하는데 매우 큰 에너지가 필요하여, 소각 방식은 실질적으로 적용이 불가능한 문제점이 있다.When discarding, the super absorbent polymer must be separated and discharged from the inside of the packaging material. If the super absorbent polymer in a gel state is disposed of in a sink or drain in a place where a separate special treatment facility is not equipped, such as at home or in a company, it is difficult to maintain the gel state. Due to the nature of the resin, the resin adheres to the inner wall of the pipe and eventually blocks the flow path. In addition, even if the resin is discharged from the pipe, it flows into the river or the sea in the state of ultra-fine plastic, which adversely affects the environment, and the superabsorbent polymer introduced into the sewage treatment plant combines with various substances to cause failure of sewage treatment equipment. There is a problem. In addition, even if the ice pack is incinerated, very large energy is required to incinerate the superabsorbent polymer in a gel state, so the incineration method has a problem in that it is practically impossible to apply.
따라서, 고흡수성 수지를 대체하거나 이미 사용된 고흡수성 수지를 재활용할 수 있는 방안이 필요한 실정이다.Therefore, there is a need for a plan that can replace the super absorbent polymer or recycle the super absorbent polymer that has already been used.
이에 본 발명의 발명자는 사용 후 버려지는 아이스팩에 충진된 고흡수성 수지를 활용함으로써 제습 및 항균 탈취 효과가 우수함을 확인하고, 본 발명을 완성하기에 이르렀다. Accordingly, the inventors of the present invention confirmed that the dehumidifying and antibacterial deodorizing effects were excellent by using the superabsorbent polymer filled in the ice pack to be discarded after use, and came to complete the present invention.
본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위하여 안출된 것으로, 본 발명의 일 목적은 아이스팩에 충진된 고흡수성 수지를 활용한 항균성 제습제의 제조방법을 제공하는데 있다.

본 발명은 아이스팩 충진제로 사용되고 있는 고흡수성 수지(SAP)에 항균성 물질을 첨가한 후, 다공성 입자 형태로 가공함으로써, 항균 및 제습 효과가 우수한 항균성 제습제의 제조방법에 관한 것이다. The present invention relates to a method for manufacturing an antibacterial dehumidifier having excellent antibacterial and dehumidifying effects by adding an antimicrobial material to a superabsorbent polymer (SAP) used as an ice pack filler and then processing it into porous particles.
본 발명에 따르면, 아이스팩으로부터 분리한 고흡수성 수지를 제습제 원료로 재활용함으로써 친환경적이고, 제조단가가 낮으며, 사용 후 상대적으로 높은 비용의 폐기 처리가 필수적으로 수반되지 않아 경제적이다. 또한, 본 발명에 따라 제조된 항균 제습제는 표면적이 넓고 다수의 기공이 포함되어 있으므로, 같은 중량의 고흡수성 수지에 비해 제습 및 항균 탈취 효과가 우수하다. 본 발명의 발명자는 이러한 결과를 거듭 확인함으로써, 본 발명을 완성하였다. According to the present invention, by recycling the superabsorbent polymer separated from the ice pack as a raw material for the desiccant, it is eco-friendly, has a low manufacturing cost, and is economical because relatively high-cost disposal treatment after use is not necessarily involved. In addition, since the antibacterial desiccant prepared according to the present invention has a large surface area and contains a large number of pores, it has excellent dehumidification and antibacterial and deodorizing effects compared to superabsorbent polymers of the same weight. The inventor of the present invention completed the present invention by repeatedly confirming these results.
본 발명의 일 실시예에 따른 항균 제습제의 제조방법은, a) 아이스팩으로부터 얻은 고흡수성 수지 100 중량부에 항균성 물질 1 내지 30 중량부, 밀가루 5 내지 30 중량부, 편백나무 분말 5 내지 10 중량부 및 첨가제 0.001 내지 5 중량부를 첨가하여 혼합물을 준비하는 단계; b) 상기 혼합물의 점도를 조절하는 단계; c) 상기 혼합물을 액적으로 분무하여 다공성의 입자를 형성하는 단계; d) 상기 입자 내 함유 수분율이 10% 이하가 되도록 건조하는 단계; 및 e) 상기 건조된 입자 표면을 아로마 오일로 코팅하는 단계를 포함한다. In the method of manufacturing an antibacterial dehumidifying agent according to an embodiment of the present invention, a) 1 to 30 parts by weight of an antibacterial material, 5 to 30 parts by weight of wheat flour, and 5 to 10 parts by weight of cypress tree powder are added to 100 parts by weight of the superabsorbent polymer obtained from an ice pack. and preparing a mixture by adding 0.001 to 5 parts by weight of an additive; b) adjusting the viscosity of the mixture; c) spraying the mixture into droplets to form porous particles; d) drying so that the moisture content in the particles is 10% or less; and e) coating the surface of the dried particles with aroma oil.
본 발명의 일 실시예에서, 상기 a) 단계의 혼합물은 고흡수성 수지에 항균성 물질과 밀가루, 편백나무 분말 및 첨가제를 더하여 준비된다.In one embodiment of the present invention, the mixture in step a) is prepared by adding an antibacterial material, wheat flour, cypress tree powder, and additives to the superabsorbent polymer.
상기 고흡수성 수지는 자기중량의 수백 배 내지 천여 배에 이르는 물을 흡수하여 보유할 수 있는 성질로 인하여, 종래에도 제습제 뿐만 아니라 기저귀 및 생리대 등 생활용품에 사용되는 물질이다. 본 발명에서는 이와 같은 특성이 있는 고흡수성 수지를 아이스팩으로부터 분리하여 재활용하는 것을 특징으로 한다. The superabsorbent polymer is a material conventionally used in household items such as diapers and sanitary napkins as well as dehumidifiers due to its property of absorbing and holding hundreds to thousands of times its own weight in water. In the present invention, it is characterized in that the superabsorbent polymer having such characteristics is separated from the ice pack and recycled.
상기 항균성 물질은 인체에 유해하지 않으며, 항균 효과가 있는 성분이라면 어느 것이든 특별히 제한되지 않으나, 바람직하게는 나린진(naringin), 키토산(Chitosan), 토코페롤(tocopherol), 테르펜(terpene), 니신(nisin), e-폴리리신(epolylysine), 나타마이신(natamycine) 및 이들의 혼합물로 이루어진 군으로부터 선택되는 1종일 수 있다. The antibacterial substance is not harmful to the human body, and any component having an antibacterial effect is not particularly limited, but is preferably naringin, chitosan, tocopherol, terpene, or nisin ), e-polylysine, natamycin, and mixtures thereof.
한편, 습기를 흡수하는 흡습성은 기상 물질인 습기를 흡수하여 조해(潮解, deliquescence)되고, 상기 조해에 의해 생성된 염 용액을 고흡수성 수지가 흡수하여 유지하는 형태로 습기 제거 메커니즘이 이루어진다. 그런데 상기 고흡수성 수지는 액상 물질에 대한 흡수력은 높으나, 저습도의 기상 물질에 대해서는 흡수력이 미미한 수준이다. 이에 따라 본 발명의 일 실시예에서는, 상기 고흡수성 수지에 항균성 물질과 더불어 밀가루와 편백나무 분말을 첨가함으로써, 기상 물질에 대한 흡수력을 향상시키는 동시에 후공정에서 상기 혼합물을 액적으로 분무하기 위해 요구되는 높은 점도 수준을 만족시킬 수 있다. 구체적으로 밀가루는 공기 중 수분에 대한 흡수력이 높으며, 편백나무 분말은 강력한 탈취 효과가 있다. 이에 따라, 고흡수성 수지에 이들을 첨가함으로써 제습 기능을 더욱 향상시킬 수 있다.On the other hand, the hygroscopic property that absorbs moisture is deliquescence by absorbing moisture, which is a gaseous material, and the moisture removal mechanism is achieved in a form in which the superabsorbent polymer absorbs and retains the salt solution generated by the deliquescence. However, the superabsorbent polymer has a high absorption capacity for liquid materials, but has a negligible absorption capacity for gaseous materials at low humidity. Accordingly, in one embodiment of the present invention, by adding wheat flour and cypress tree powder to the superabsorbent polymer along with an antibacterial material, the absorption capacity for gaseous substances is improved and at the same time required for spraying the mixture into droplets in a subsequent process High viscosity levels can be satisfied. Specifically, flour has a high absorbency for moisture in the air, and cypress tree powder has a strong deodorizing effect. Accordingly, the dehumidifying function can be further improved by adding them to the superabsorbent polymer.
본 발명의 일 실시예에서, 혼합물에 첨가되는 상기 첨가제는 필요에 따라 계면활성제, 가용화제, 점도조절제, 코팅제, 보존제 및 분산제로 이루어진 군으로부터 선택되는 1종 이상의 물질일 수 있으나, 이에 한정되는 것은 아니다. 상기 첨가제는 본 발명에 따라 제조되는 제습제의 물성 및 특성에 영향을 주지 않는 상기 범위 내에서 적절히 첨가될 수 있다.In one embodiment of the present invention, the additives added to the mixture may be one or more materials selected from the group consisting of surfactants, solubilizers, viscosity modifiers, coating agents, preservatives, and dispersants, if necessary, but are not limited thereto no. The additives may be appropriately added within the above ranges that do not affect the physical properties and characteristics of the desiccant prepared according to the present invention.
본 발명의 일 실시예에서, 상기 b) 단계는 앞서 준비된 혼합물의 점도를 10,000 내지 30,000 CPS로 조절할 수 있다. 이 때, 상기 점도는 공지된 방법에 의해 조절할 수 있으며, 바람직하게는 혼합물에 용매로서 물과 점도조절제를 첨가하고, 진공상태에서 용매를 휘발시켜 점도를 조절하고, 혼합물 내 갇혀 있는 미세기포를 제거함으로써 탈포하여 점도를 안정화한다. 이 때, 혼합물의 점도에 따라 표면 거칠기가 높고 균일한 기공을 갖는 다공성의 입자의 형성 여부가 결정된다. 높은 표면 거칠기 및 다공성 입자의 형성은 넓은 표면적을 확보할 수 있고, 이는 곧 공기 중 분자와 접촉할 수 면적을 의미하므로, 궁극적으로 항균 및 제습 효과를 증진시킬 수 있게 된다. 만약 점도가 상기 범위보다 낮은 경우, 에어 노즐을 이용한 스프레이 분사 방법으로 입자를 형성하는데 있어서 입자의 크기 및 강도가 적합하지 않으며, 기공을 갖는 다공성 입자를 형성하기 어렵다. 반면, 점도가 상기 범위보다 높은 경우, 에어 노즐을 이용한 스프레이 분사 방법을 적용하는 것 자체가 용이하지 않다. 이러한 점에서 상기 혼합물의 점도는 10,000 내지 30,000 CPS를 만족하는 것이 바람직하며, 더 바람직하게는 15,000 내지 25,000 CPS일 수 있다. In one embodiment of the present invention, step b) may adjust the viscosity of the previously prepared mixture to 10,000 to 30,000 CPS. At this time, the viscosity can be adjusted by a known method, and preferably, water and a viscosity modifier are added as a solvent to the mixture, the solvent is volatilized in a vacuum state to adjust the viscosity, and microbubbles trapped in the mixture are removed. By doing so, the viscosity is stabilized by defoaming. At this time, whether to form porous particles having high surface roughness and uniform pores is determined according to the viscosity of the mixture. Formation of high surface roughness and porous particles can secure a large surface area, which means an area that can come into contact with molecules in the air, so that antibacterial and dehumidifying effects can ultimately be enhanced. If the viscosity is lower than the above range, the size and strength of the particles are not suitable for forming the particles by the spray injection method using an air nozzle, and it is difficult to form porous particles having pores. On the other hand, when the viscosity is higher than the above range, it is not easy to apply the spray injection method using an air nozzle itself. In this respect, the viscosity of the mixture is preferably 10,000 to 30,000 CPS, and more preferably 15,000 to 25,000 CPS.
본 발명의 일 실시예에서, 상기 c) 단계는 혼합물을 에어 노즐에 투입한 후, 압력을 가하여 분사함으로써, 10 내지 100 mm의 크기를 갖는 다공성 입자를 형성할 수 있다. 이 때, 상기 다공성 입자는 표면에 0.01 내지 0.08 mm의 크기의 기공을 형성함으로써, 넓은 표면적을 확보할 수 있다. In one embodiment of the present invention, step c) may form porous particles having a size of 10 to 100 mm by injecting the mixture into an air nozzle and then applying pressure to spray it. At this time, a large surface area can be secured by forming pores having a size of 0.01 to 0.08 mm on the surface of the porous particle.
본 발명의 일 실시예에서, 상기 d) 단계의 건조는 상기 형성된 다공성 입자 내 함유 수분율이 10% 이하가 되도록 건조 과정을 수행할 수 있다. 그 방법에 있어서, 특별히 제한되지 않으나, 바람직하게는 70 내지 80 ℃의 온도에서 20 내지 30 시간 동안 방치하여 수행될 있다. In one embodiment of the present invention, the drying in step d) may be performed such that the moisture content in the formed porous particles becomes 10% or less. The method is not particularly limited, but is preferably carried out by leaving it at a temperature of 70 to 80 ° C. for 20 to 30 hours.
본 발명의 일 실시예에서, 상기 e) 단계는 상기 건조된 입자 표면에 아로마 오일을 도포 내지 분사함으로써 항균, 탈취 및 방향 기능을 더욱 부여할 수 있다. 이 때, 상기 아로마 오일은 항균, 탈취, 방향에 효과적인 것이라면 어느 것이나 제한되지 않으나, 바람직하게는 편백오일, 스피어민트 및 그린티를 각 1:1:1로 혼합한 것일 수 있다. In one embodiment of the present invention, step e) may further impart antibacterial, deodorizing and fragrance functions by applying or spraying aroma oil on the surface of the dried particles. At this time, the aroma oil is not limited to any one effective for antibacterial, deodorizing, and aromatic, but may preferably be a mixture of cypress oil, spearmint, and green tea in a ratio of 1:1:1.
아울러, 본 발명은 다른 일 실시예에서, 상기 항균 제습제의 제조방법에 의하여 제조된 항균 제습제를 제공한다. 상기 방법에 의하여 제조된 항균 제습제는 표면적이 넓고 다수의 기공이 포함되어 있으므로, 같은 중량의 고흡수성 수지에 비해 제습 및 항균 탈취 효과가 우수하다. 따라서, 이에 따라 제조된 항균 제습제는 실내용 또는 차량용 제습제, 건조식품, 곡물류, 제약류 및 전기, 정밀기기 등의 수분에 의한 열화를 방지를 필요로 하는 분야에 다양하게 사용될 수 있다.In addition, in another embodiment, the present invention provides an antibacterial desiccant prepared by the method for preparing the antibacterial desiccant. Since the antibacterial desiccant prepared by the above method has a large surface area and contains a large number of pores, it has excellent dehumidification and antibacterial and deodorizing effects compared to superabsorbent polymers of the same weight. Therefore, the antibacterial desiccant prepared according to this method can be used in a variety of fields requiring deterioration due to moisture, such as indoor or vehicle dehumidifiers, dried foods, grains, pharmaceuticals, electricity, and precision instruments.
이하에서는, 구체적인 실시예를 통하여 본 발명을 더욱 상세하게 설명한다. 하기 실시예는 본 발명의 바람직한일 구체예를 기재한 것이며, 하기 실시예의 기재 사항의 범위 내로 본 발명의 권리범위가 한정되는 것은 아니다. Hereinafter, the present invention will be described in more detail through specific examples. The following examples describe preferred embodiments of the present invention, and the scope of the present invention is not limited within the scope of the descriptions of the following examples.
실시예 1.Example 1.
아이스팩으로부터 얻은 고흡수성 수지 100 중량부에 나린진과 토코페롤을 각 5 중량부씩 첨가하고, 밀가루 12 중량부, 편백나무 분말 10 중량부, 가용화제 0.5 중량부, 색소 0.01 중량부를 더하여 혼합하였다. 상기 혼합물에 물과 점도조절제를 첨가하고, 진공상태에서 용매를 휘발시키고, 탈포하여 점도가 15,000 CPS가 되도록 조절하였다. 상기 배합한 혼합물을 스프레이 분사 노즐에 투입하고 액적으로 분무하여 약 60~90 mm 크기의 입자를 형성하였다. 이어서, 상기 형성된 입자를 70 ℃의 온도에서 30 시간 동안 건조시켰다. 건조과정을 통해 수분의 증발로 입자의 크기가 처음 대비 약 30% 부피 이하로 감소되었다. 상기 건조된 입자 표면에 편백오일, 스피어민트 및 그린티를 각 1:1:1로 혼합한 아로마 오일을 분사하여 코팅함으로써, 본 발명에 따른 항균 제습제를 제조하였다. 5 parts by weight each of naringin and tocopherol were added to 100 parts by weight of the superabsorbent polymer obtained from the ice pack, and 12 parts by weight of wheat flour, 10 parts by weight of cypress tree powder, 0.5 part by weight of solubilizing agent, and 0.01 part by weight of pigment were added and mixed. Water and a viscosity modifier were added to the mixture, the solvent was volatilized in a vacuum, and the viscosity was adjusted to 15,000 CPS by defoaming. The blended mixture was put into a spray nozzle and sprayed into droplets to form particles having a size of about 60 to 90 mm. Then, the formed particles were dried at a temperature of 70 °C for 30 hours. Due to the evaporation of moisture through the drying process, the size of the particles was reduced to about 30% less than the original volume. An antibacterial dehumidifier according to the present invention was prepared by spraying and coating the surface of the dried particles with aroma oil mixed with cypress oil, spearmint and green tea in a ratio of 1:1:1.
비교예 1. Comparative Example 1.
상기 실시예 1에서 혼합물을 탈포하여 점도가 15,000 CPS가 되도록 조절하는 단계 및 상기 혼합물을 스프레이 분사하여 액적을 형성하는 단계를 거치지 않은 것을 제외하고는, 실시예 1과 동일한 방법으로 항균 제습제를 제조하였다. An antibacterial dehumidifying agent was prepared in the same manner as in Example 1, except that the step of degassing the mixture to adjust the viscosity to 15,000 CPS and the step of spraying the mixture to form droplets were not performed. .
비교예 2. Comparative Example 2.
상기 실시예 1에서 고흡수성 수지에 밀가루와 편백나무 분말을 첨가하지 않은 혼합물을 준비하는 단계, 상기 혼합물을 탈포하여 점도가 15,000 CPS가 되도록 조절하는 단계 및 상기 혼합물을 스프레이 분사하여 액적을 형성하는 단계를 거치지 않은 것을 제외하고는, 실시예 1과 동일한 방법으로 항균 제습제를 제조하였다. Preparing a mixture in Example 1 in which flour and cypress tree powder were not added to the superabsorbent polymer, adjusting the viscosity to 15,000 CPS by defoaming the mixture, and spraying the mixture to form droplets An antibacterial dehumidifying agent was prepared in the same manner as in Example 1, except that it did not go through.
실험예 1. 흡습율 평가Experimental Example 1. Evaluation of moisture absorption
실시예 1 및 비교예 1에서 제조된 항균 제습제의 최대 흡습율을 평가하고, 그 결과를 하기 표 1에 나타내었다.The maximum moisture absorption rate of the antibacterial desiccant prepared in Example 1 and Comparative Example 1 was evaluated, and the results are shown in Table 1 below.
흡습율은 온도 30 ℃ 및 상대습도 80%로 습도가 높은 환경에 5일 동안 지속적으로 노출시켜 흡습율을 측정하였다.The moisture absorption rate was measured by continuously exposing to a high humidity environment at a temperature of 30 °C and a relative humidity of 80% for 5 days.
상기 표 1에서와 같이, 실시예 1에 따라 제조된 제습제의 경우, 흡습율이 비교예 대비 현저히 높은 것을 확인할 수 있다.반면, 비교예 1의 경우, 실시예 1의 혼합물과 동일하게 제조되었음에도 불구하고, 실시예 1 대비 현저히 낮은 흡습율을 보였다.As shown in Table 1, in the case of the desiccant prepared according to Example 1, it can be confirmed that the moisture absorption rate is significantly higher than that of the comparative example. And, compared to Example 1, it showed a significantly lower moisture absorption rate.
또한, 비교예 2의 경우, 비교예 1의 혼합물과 일부 성분의 차이만 있을 뿐, 동일한 제조과정을 거쳐 제조되었음에도 비교예 1 대비 더욱 낮은 흡습율을 보였다.In addition, in the case of Comparative Example 2, there was only a difference in some components from the mixture of Comparative Example 1, and even though it was manufactured through the same manufacturing process, it showed a lower moisture absorption rate than Comparative Example 1.
이러한 결과는, 본 발명의 실시예 1에서 10,000 CPS 이상의 높은 점도를 갖는 혼합물을 사용하여 액적을 형성하는 경우, 다공성의 입자가 형성되어 공기 중에 물 분자와 접촉하는 표면적이 더 크기 때문인 것으로 판단된다.It is believed that this result is due to the fact that when droplets are formed using a mixture having a high viscosity of 10,000 CPS or more in Example 1 of the present invention, porous particles are formed and the surface area in contact with water molecules in the air is larger.
또한, 혼합물 내에서 밀가루 및 편백나무 분말이 기체 상태의 수분에 대한 흡수력이 크기 때문에 이들을 포함하는 혼합물을 사용하여 제습제를 제조한 경우, 흡습율이 보다 향상되는 것으로 판단된다. In addition, since flour and cypress tree powder have a high absorption capacity for gaseous moisture in the mixture, it is judged that the moisture absorption rate is further improved when the desiccant is prepared using a mixture containing them.
실험예 2. 폼알데하이드 탈취 시험Experimental Example 2. Formaldehyde deodorization test

However, the detection limit was set at 0.5 umol/mol.
