Can sandalwood be used in in addition to formaldehyde?
Sandalwood can only mask the smell of formaldehyde, which is still there. Besides sandalwood, oranges, pomelos, mangoes, durians and so on all have similar effects. Some indoor green plants, such as reeds in Phnom Penh, can even purify formaldehyde through certain procedures. Suggest a try.
Effective method for remove formaldehyde
1, ventilation mode
Ventilation method does not need too much explanation, that is, it discharges harmful gases to the outside through the flow of air. This is a simple and effective method. The only drawback is that the formaldehyde release cycle is long, usually three to fifteen years. It is obviously unrealistic to leave the new house idle for more than three years after renovation. Because of this, ventilation alone cannot meet the requirements.
2. Plant-derived air purification liquid
AQ air purification spray plant-derived biological preparation, using biotechnology, refined and extracted its effective components, such as sesquiterpene polyesters and alcohol compounds, from plants such as Populus euphratica, Robinia pseudoacacia, Melia azedarach, etc., and made a plant-derived compound purification liquid with exclusive patent formula, with remarkable and lasting sterilization effect. Tested by authoritative departments such as Hong Kong Polytechnic University, it is effective against Salmonella, Shigella, pathogenic Escherichia coli, Vibrio cholerae, Staphylococcus aureus, Legionella and SARS coronavirus. And effectively decompose toxic gases such as formaldehyde, benzene and TVOC. Instantaneous decomposition, no secondary pollution. Can enter the eye.
3, formaldehyde scavenger or formaldehyde dissolving enzyme
Formaldehyde scavenger "removes" formaldehyde through chemical reaction, the essence of which is to reduce the toxicity of the target substance or convert it into non-toxic substance. Formaldehyde can be oxidized to formic acid or reduced to methanol. Although the toxicity and irritation of these two substances are lower than formaldehyde, their toxicity still exists. For example, some highly oxidizing formaldehyde scavengers can oxidize formaldehyde, but they are easy to decompose by themselves. Spraying on the board will damage the wood, and it will be ineffective within a few hours. It is impossible to "spray it to the end". In addition, the high concentration scavenger sprayed in the air will cause new pollution hazards to people. Other oxidants and reductants can not effectively remove formaldehyde, and will also introduce similar new pollution.
4. Activated carbon adsorption
Teacher Li, who specializes in activated carbon in Nankai University, told the reporter that the initial use of activated carbon did have an effect, because the pores had adsorption potential, which was formed by the mutual attraction of carbon molecules and adsorbed molecules. The smaller the aperture, the stronger the adsorption potential. In addition, according to the theory of molecular motion, all objects are composed of molecules or atoms, and there are gaps between them, and at the same time they are in an endless state of random thermal motion, and molecules collide frequently. According to relevant data, in the standard state, the free movement speed of formaldehyde molecule is about 450m/s, and one formaldehyde molecule collides with other molecules 109 times per second. At this time, if the diameter of the collision molecule matches the pore of the activated carbon, it is adsorbed. Both traditional activated carbon and fried modified activated carbon have limited adsorption capacity because of too large pores.
The maximum temperature of sunlight is only about 50 degrees Celsius, which can only evaporate water. The pollutants adsorbed by activated carbon can not be completely volatilized, and the adsorption function of carbon can not be completely restored. So exposure is more about removing water from activated carbon. The adsorption performance cannot be recovered.
Generally, activated carbon has a certain adsorption effect on benzene, but the adsorption effect on formaldehyde is not obvious. Generally, the adsorption capacity of activated carbon will weaken after one month.
5. Soak in water, vinegar and black tea to remove formaldehyde.
Many people on the Internet say that because formaldehyde is soluble in water, you can put more pots at home to absorb formaldehyde, or soak it in vinegar or black tea. It is a fact that formaldehyde is soluble in water, water, alcohol and ether. Free formaldehyde in the air will dissolve into it when it meets water during movement, which is similar to the adsorption principle of activated carbon. The contact area between a basin of water and air is only the size of a basin, while the specific surface area of internal pores of 1g activated carbon can reach the size of a football field. Even if you put a hundred pots of water in the room, the adsorption effect will not be much stronger than 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 temperature. With the increase of humidity in the air, the release of formaldehyde will greatly increase. The experimental results show that when the relative temperature in the air increases 10%, the indoor formaldehyde emission will increase by about 5%.
Can sandalwood be used in in addition to formaldehyde? To sum up, sandalwood can help people effectively remove the unpleasant smell in the air, but if you want to use it to remove formaldehyde, it is unlikely. Even though the pungent smell of formaldehyde is masked by the smell of sandalwood, it still exists in the indoor air. Don't think that there is no formaldehyde without pungent smell in the room. Also, formaldehyde may be colorless and odorless, and it may remain indoors for several months. Everyone should be at ease.
