1、濟南除甲醛公司:負離子凈化

1. Jinan Formaldehyde Removal Company: Negative Ion Purification

室內(nèi)甲醛分子結(jié)構(gòu)的尺寸在0.27納米技術(shù)上下,表層種群的功效及其吸咐質(zhì),空氣負離子與氣體中的病原菌體細胞融合后,使體細胞內(nèi)部能量轉(zhuǎn)移、構(gòu)造更改,造成其身亡,使氣體中飄浮的煙、塵、蜂花粉等吸進細顆粒物聚集而大自然地基沉降,超過凈化室內(nèi)空氣的目的.

The size of indoor formaldehyde molecular structure is above and below 0.27 nanometer technology, the effect of surface population and its absorbent substance, the fusion of air negative ions and pathogenic bacteria cells in the gas, causes the energy transfer and structural change inside the body cells, resulting in its death, and causes the floating smoke, dust, bee pollen in the gas to absorb fine particulate matter and the natural foundation to settle, exceeding the purpose of purifying indoor air.

優(yōu)點:使用比較簡單;高壓放電等技術(shù)使空氣產(chǎn)生負離子,負離子與空氣中的顆粒污染物結(jié)合,使微小的顆粒聚集、沉降,對凈化空氣有一定作用.

Advantages: It is relatively simple to use; high voltage discharge and other technologies make air produce negative ions, which combine with particulate pollutants in the air, make tiny particles gather and settle, and have a certain role in purifying air.

2、用水、醋、紅茶泡水去除甲醛

2. Removal of formaldehyde with water, vinegar and black tea

在網(wǎng)上許多人詳細介紹說,因為甲醛溶于水,能夠在家中多放好多個水槽用于去除甲醛,或是用醋或綠茶泡茶等方式 .室內(nèi)甲醛溶于于水、水、醇和醚它是客觀事實,氣體中的礦酸室內(nèi)甲醛健身運動全過程中碰到水之后融入在其中,這與活性碳的吸咐基本原理相近.一盆水與空氣的接觸面積只有水盆的大小,而1克活性炭內(nèi)部孔隙的比表面積可以達到一個足球場那么大.即使在房間內(nèi)放一百盆水,其實吸附效果不會比一小包活性炭強多少.因此利用水、紅茶、醋等方法來吸附甲醛,顯然是不現(xiàn)實的.甲醛的釋放與室內(nèi)的溫度和濕度密切相關(guān),空氣中溫度增加,甲醛的釋放量會大大增加.實驗結(jié)果表明,空氣中相對溫度增加10%,室內(nèi)甲醛釋放量會增加5%左右.

Many people on the Internet have explained in detail that because formaldehyde dissolves in water, it can put many more sinks at home to remove formaldehyde, or use vinegar or green tea to make tea. Indoor formaldehyde dissolves in water, water, alcohol and ether. It is an objective fact that indoor formaldehyde in mineral acid in the gas is integrated into the whole process of indoor formaldehyde fitness exercise after meeting water, which is similar to the basic principle of activated carbon absorption. The contact area with air is only the size of the water basin, and the specific surface area of the pore inside 1 gram of activated carbon can reach the size of a football field. Even if a hundred pots of water are placed in the room, the adsorption effect will not be much stronger than that of a small bag of activated carbon. Therefore, it is obviously unrealistic to use water, black tea and vinegar to adsorb formaldehyde. The release of formaldehyde is closely related to indoor temperature and humidity. With the increase of air temperature, the formaldehyde emission will increase greatly. The experimental results show that the relative air temperature increases by 10%, and the indoor formaldehyde emission will increase by about 5%.

植物吸收甲醛

Formaldehyde absorption by plants

植物能夠通過光合作用吸入部分有害物質(zhì),但這類方法的作用極為有限.原因如下:

Plants can inhale some harmful substances through photosynthesis, but the effects of these methods are extremely limited. The reasons are as follows:

1)、綠色植物開展的是植物光合作用,通常在大白天吸進一部分有害物,而在夜里不具有這一作用.人的衣食住行規(guī)律性通常全是大白天戶外,夜里在房間內(nèi),在人最必須空氣過濾時,綠色植物沒有方法具有相對的功效.

1) Green plants carry out photosynthesis, which usually absorbs a part of harmful substances in the daytime, but not at night. The regularity of people's food, clothing, living and transportation is usually outdoors in the daytime. At night, in the room, when people most need air filtration, green plants have no method to have relative efficacy.

2)、綠色植物消化吸收的有害物極其不足.國家行業(yè)標準對室內(nèi)甲醛的釋放出來值規(guī)定小于0.08mg/立方,絕大多數(shù)剛室內(nèi)裝修完的房屋,室內(nèi)甲醛高于0.2mg/立方,而去除甲醛高效率較高的綠籮,每鐘頭消化吸收的室內(nèi)甲醛僅為20微克.以一個100平米,房高3米,甲醛值為0.2毫克/立方米的房間來講,同時需要1800盆綠蘿,幾乎要把整個房子空間添滿,才能將甲醛降為0.08毫克,這還是在白天光線充足的情況下進行的、并且要保證在進行吸收的過程中不再有甲醛的釋放.而事實上裝修后的家具中甲醛還在一直不斷釋放.因此,植物僅能對甲醛、苯等有害物質(zhì)起到輔助的治理作用.

2) The harmful substances digested and absorbed by green plants are extremely inadequate. The release value of indoor formaldehyde is less than 0.08 mg/cubic according to national industry standards. Most newly decorated houses have indoor formaldehyde higher than 0.2 mg/cubic. The green bamboo with high formaldehyde removal efficiency only absorbs 20 mg of indoor formaldehyde per hour. With a 100 square meter, the room height is 3 meters, and the formaldehyde value is 0.2 mg/cubic. For a square-meter room, it also needs 1800 pots of green radish to fill up the whole room space, so that formaldehyde can be reduced to 0.08 mg. This is still done in the daytime when the light is sufficient and no formaldehyde is released during the absorption process. In fact, formaldehyde is still continuously released in the furniture after decoration. Therefore, plants can only be harmful to formaldehyde, benzene and other harmful substances. Quality plays an auxiliary role in governance.

6、植物源

6. Plant Sources

植物源空氣凈化噴灑霧化為萜類化合物具有廣泛生物活性,但依賴植物體的傳統(tǒng)生產(chǎn)方式是推廣應(yīng)用的瓶頸之一.采用合成生物學(xué)策略,創(chuàng)制微生物"細胞工廠",有望為植物源萜類化合物低成本、可持續(xù)供給提供先進技術(shù).丹參酮為我國傳統(tǒng)中藥丹參的主要脂溶性活性成分,屬于松香烷類去甲二萜化合物.該研究組與中醫(yī)科學(xué)院中藥資源中心黃璐琦研究員課題組合作,前期構(gòu)建了高產(chǎn)丹參酮合成前體次丹參酮二烯的酵母工程菌株(J. Am. Chem. Soc.,2012, 134(6): 3234). 

Atomization of terpenoids from plant-derived air purification spraying has a wide range of biological activities, but the traditional production mode depending on plants is one of the bottlenecks to promote its application. Using synthetic biology strategy to create a microbial "cell factory" is expected to provide advanced technology for low-cost and sustainable supply of terpenoids from plant sources. Tanshinone is the main lipid-soluble active ingredient of Tanshinone, a traditional Chinese medicine. A yeast engineering strain (J. Am. Chem. Soc., 2012, 134 (6): 3234) producing tanshinone diene precursor was constructed by our team in collaboration with Huang Luqi, a researcher at the Center of Traditional Chinese Medicine Resources, Chinese Academy of Sciences. http://www.whkjgn.com./
