1、济南除甲醛公司:负离子净化

1. Jinan Formaldehyde Removal Company: Negative Ion Purification

室内甲醛分子结构的尺寸在0.27纳米技术上下,表层种群的功效及其吸咐质,空气负离子与气体中的病原菌体细胞融合后,使体细胞內部能量转移、构造更改,造成其身亡,使气体中飘浮的烟、尘、蜂花粉等吸进细颗粒物聚集而大自然地基沉降,超过净化室内空气的目的.

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.

优点:使用比较简单;高压放电等技术使空气产生负离子,负离子与空气中的颗粒污染物结合,使微小的颗粒聚集、沉降,对净化空气有一定作用.

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、红茶泡水去除甲醛

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

在网上许多人详细介绍说,因为甲醛溶于水,能够在家中多放好多个水槽用于去除甲醛,或是用醋或绿茶泡茶等方式 .室内甲醛溶于于水、水、醇和醚它是客观事实,气体中的矿酸室内甲醛健身运动全过程中碰到水之后融入在其中,这与活性碳的吸咐基本原理相近.一盆水与空气的接触面积只有水盆的大小,而1克活性炭内部孔隙的比表面积可以达到一个足球场那么大.即使在房间内放一百盆水,其实吸附效果不会比一小包活性炭强多少.因此利用水、红茶、醋等方法来吸附甲醛,显然是不现实的.甲醛的释放与室内的温度和湿度密切相关,空气中温度增加,甲醛的释放量会大大增加.实验结果表明,空气中相对温度增加10%,室内甲醛释放量会增加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

植物能够通过光合作用吸入部分有害物质,但这类方法的作用极为有限.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)、绿色植物开展的是植物光合作用,通常在大白天吸进一部分有害物,而在夜里不具有这一作用.人的衣食住行规律性通常全是大白天户外,夜里在房间内,在人最必须空气过滤时,绿色植物沒有方法具有相对的功效.

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)、绿色植物消化吸收的有害物极其不足.国家行业标准对室内甲醛的释放出来值规定小于0.08mg/立方,绝大多数刚室内装修完的房屋,室内甲醛高于0.2mg/立方,而去除甲醛高效率较高的绿箩,每钟头消化吸收的室内甲醛仅为20微克.以一个100平米,房高3米,甲醛值为0.2毫克/立方米的房间来讲,同时需要1800盆绿萝,几乎要把整个房子空间添满,才能将甲醛降为0.08毫克,这还是在白天光线充足的情况下进行的、并且要保证在进行吸收的过程中不再有甲醛的释放.而事实上装修后的家具中甲醛还在一直不断释放.因此,植物仅能对甲醛、苯等有害物质起到辅助的治理作用.

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

植物源空气净化喷洒雾化为萜类化合物具有广泛生物活性,但依赖植物体的传统生产方式是推广应用的瓶颈之一.采用合成生物学策略,创制微生物"细胞工厂",有望为植物源萜类化合物低成本、可持续供给提供先进技术.丹参酮为我国传统中药丹参的主要脂溶性活性成分,属于松香烷类去甲二萜化合物.该研究组与中医科学院中药资源中心黄璐琦研究员课题组合作,前期构建了高产丹参酮合成前体次丹参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.jntkzl.com./
