We all know that new houses contain formaldehyde. In order to prevent people living in them from absorbing formaldehyde, people with plenty of time will choose to buy a house early, decorate it early, and then ventilate the house frequently to remove the formaldehyde inside. But if the house is to be used urgently and the formaldehyde in the house has not been completely eliminated, what professional methods can we use to remove formaldehyde? Formaldehyde is a colorless gas with a strong irritating odor. It is easily soluble in water and appears in the form of aqueous solution. Soluble in water, ethanol, alcohol and ether. Formaldehyde is a gas at room temperature, and a 35-40% formaldehyde aqueous solution is usually called formalin. The aldehyde group in the formaldehyde molecule undergoes condensation reaction to obtain phenolic resin (Bakelite). Formaldehyde is an important organic raw material, mainly used in the plastics industry (such as phenolic resin, urea-formaldehyde plastic - electroplating), synthetic fibers (such as synthetic vinylon - polyvinyl formal), leather industry, medicine, dyes, etc. Open windows to keep the house ventilated. By allowing the indoor air to circulate naturally, harmful gases in the room can be removed and diluted. This method is the most primitive and the most effective method. Plant removal method. Such plants include spider plants, tiger plants, ivy, aloe vera, agave, and gerbera. Activated carbon adsorption method. Using activated carbon and bamboo charcoal with adsorption function to remove these harmful gases is also the most widely used method at present. However, one thing is certain: the active carbon has a small working space. If the space is large, the amount of activated carbon required will also be larger. Formaldehyde removal method. This method is the most direct and effective, but the requirements for products are also very professional. Currently, such products include chemical products, nano photocatalysts, plant liquid formaldehyde removal products, etc. This type of product will cause some "secondary pollution" so use it with caution. Local method. Soak 300 grams of black tea in two basins of water, put it in the room, and open the window for ventilation. You can also put some grapefruit peels, orange peels, pineapples, etc. indoors. These things all have a certain effect. What harm does formaldehyde do to the human body? 1. Stimulation The main hazard of formaldehyde is its irritation to the skin and mucous membranes. Formaldehyde is a protoplasmic toxic substance that can combine with protein. When inhaled in high concentrations, it can cause severe respiratory irritation and edema, eye irritation, and headaches. 2 Sensitization Direct skin contact with formaldehyde can cause allergic dermatitis, pigmentation, and necrosis, while inhalation of high concentrations of formaldehyde can induce bronchial asthma. 3 Mutagenic effect High concentrations of formaldehyde are also a genotoxic substance. Experimental animals may develop nasopharyngeal tumors if they inhale high concentrations in the laboratory. |
