Description
本創作是有關於一種抗菌抗病毒的奈米複合過濾材，尤指一種結合奈米活性層及空氣過濾層的奈米複合過濾材，能有效過濾空氣中細菌、病毒、消除空氣中的有害氣體如甲醛等及PM2.5，達到淨化空氣的效果。 This creation is about an antibacterial and antiviral nanocomposite filter material, especially a nanocomposite filter material that combines a nano active layer and an air filter layer, which can effectively filter bacteria and viruses in the air and eliminate harmful gases in the air Such as formaldehyde and PM2.5, to achieve the effect of purifying the air.
隨著科技的發展，造成氣候變遷、全球暖化，使得環境空氣品質逐漸惡化且日趨嚴重，室內環境的空氣污染程度更是遠超過一般人的想像。空氣中存在許多肉眼看不見的微小污染粒子，如細菌、病毒、灰塵、油煙、塵埃、煙霧與有害氣體等，都不斷地從建築物、裝飾材料、電器用品等各種現代化的設備裏面釋放出來，而這些都會危害人體的健康；近年來環境空氣汙染日益嚴重，尤其是細菌及病毒的傳播，已經對人體健康造成嚴重的威脅。惟，面對室外環境汙染，人們長期使用紗門及紗窗來過濾空氣，對PM2.5、有害氣體及細菌、病毒的去除效果不甚理想。再者，由於長久以來人們依賴空調設備所帶來的舒適，但是，空調設備不具過濾機能，在循環的過程，也代表病菌等汙染物可以透過這個途徑傳播到室內所有人員。 With the development of science and technology, climate change and global warming have caused the environmental air quality to gradually deteriorate and become more serious. The degree of air pollution in the indoor environment is far more than ordinary people's imagination. There are many tiny pollutants in the air that are invisible to the naked eye, such as bacteria, viruses, dust, oily smoke, dust, smoke, and harmful gases, which are constantly released from various modern equipment such as buildings, decorative materials, and electrical appliances. All of these will endanger human health; in recent years, environmental air pollution has become more and more serious, especially the spread of bacteria and viruses, which have caused serious threats to human health. However, in the face of outdoor environmental pollution, people use screen doors and screen windows to filter the air for a long time, and the effect of removing PM2.5, harmful gases, bacteria and viruses is not ideal. Furthermore, because people have long relied on air-conditioning equipment for comfort, but air-conditioning equipment does not have a filtering function, in the process of circulation, it also means that pollutants such as germs can spread to all people indoors through this route.
為了解決這項問題，人們需求使用具有除塵、殺菌、殺病毒、除臭、防霉等作用的空氣濾網與現有空調設備結合，不會降低空調設備的性能，使我們生活環境更為健康、舒適。 In order to solve this problem, people need to use air filters that have the functions of dust removal, sterilization, virus killing, deodorization, and mildew resistance to combine with existing air conditioning equipment, which will not reduce the performance of air conditioning equipment and make our living environment healthier. Comfortable.
故，如何突破既有紗門、紗窗及空調設備的缺失，來大幅提高其使用效益，並有效防止環境中PM2.5及抑制細菌、病毒的滋生及傳播，實為一具實用價值之技術課題。 Therefore, how to break through the lack of existing screen doors, screen windows and air-conditioning equipment to greatly improve their use efficiency and effectively prevent PM2.5 in the environment and inhibit the growth and spread of bacteria and viruses is a technical subject of practical value.
如本國專利公告的第M513804號揭示一種車用多功能空調濾網，乃利用結合有靜電過濾層、活性碳中間層與負離子抗菌層之三層結構，從而可將靜電過濾去除細懸浮微粒(PM2.5)、活性碳除臭及消除有害氣體甲醛甲苯等、抗菌防霉、分解一氧化碳與產生負離子淨化空氣等多種功能整合為一，使汽車空調濾網的空氣濾淨效果獲得大幅提昇，將有助於提昇車內環境之空氣清新度，可維護乘車者的舒適和健康，藉以提升產品的附加價值及創造經濟效益。 For example, the national patent publication No. M513804 discloses a multifunctional air-conditioning filter for vehicles, which uses a three-layer structure that combines an electrostatic filter layer, an activated carbon intermediate layer and an anion antibacterial layer, so that the electrostatic filter can remove fine suspended particles (PM2). .5) Activated carbon deodorization and elimination of harmful gases such as formaldehyde and toluene, antibacterial and anti-mold, decomposition of carbon monoxide and generation of negative ions to purify the air, and other functions are integrated into one, so that the air filtration effect of the car air conditioning filter can be greatly improved. It helps to improve the freshness of the air in the car environment, and can maintain the comfort and health of the occupants, thereby enhancing the added value of the product and creating economic benefits.
如本國專利公告的第M570401號揭示一種複合機能空調濾網，乃結合有靜電過濾層、活性碳中間層、負離子抗菌層與多酚抗自由基層等四種結構，其中負離子抗菌層與多氛抗自由基層也可整合為一層，以達到靜電過濾去除細懸浮微粒(PM2.5)、活性碳除臭、產生負離子消除有害氣體、抗菌防霉以及天然多氛的抗氧化、抗自由基等複合功能整合為一，同時避免可能導致人體不適的香氛或異味，藉以提供消費者具完整機能的空調濾網，來滿足規格日趨嚴謹之濾網產品的各項要求。 For example, the national patent announcement No. M570401 discloses a composite function air conditioning filter, which combines four structures: an electrostatic filter layer, an activated carbon intermediate layer, an anion antibacterial layer and a polyphenol anti-radical layer. The free radical layer can also be integrated into one layer to achieve electrostatic filtration to remove fine suspended particles (PM2.5), activated carbon deodorization, generation of negative ions to eliminate harmful gases, antibacterial and anti-mildew, and natural atmosphere's anti-oxidation, anti-free radical and other composite functions Integrate into one, while avoiding fragrances or odors that may cause discomfort to the human body, so as to provide consumers with air-conditioning filters with complete functions to meet the requirements of increasingly stringent filter products.
綜合上述專利主要揭示空調濾網的功能改進，惟，目前空氣過濾網主要使用靜電棉利用靜電吸附粉塵達到高過濾效率，但靜電會隨時 間衰退或受環境影響，且以負離子抗菌層或多酚自由基層對細菌及病毒抑制效果不甚理想。面對日趨嚴重的空氣汙染及細菌病毒的傳播急需有一種過濾效率不受環境影響、低壓差及容易與現有紗窗、紗門及空調設備結合的過濾材，期能達到淨化空氣的功效。 The above-mentioned patents mainly reveal the functional improvement of the air-conditioning filter. However, the current air filter mainly uses electrostatic cotton to absorb dust to achieve high filtration efficiency, but static electricity will always Decay or be affected by the environment, and the negative ion antibacterial layer or polyphenol free radical layer has an unsatisfactory inhibitory effect on bacteria and viruses. In the face of increasingly serious air pollution and the spread of bacteria and viruses, there is an urgent need for a filter material that is not affected by the environment, has a low pressure difference, and is easily integrated with existing screen windows, screen doors and air conditioning equipment, and is expected to achieve the effect of purifying the air.
