Formaldehyde is a colorless, pungent gas with a strong odor, and its 35% to 40% aqueous solution is known as formalin. Formaldehyde is a pure syrup poison. The main health hazards of formaldehyde are as follows:

a. Stimulating effect: The main hazard of formaldehyde is the stimulating effect on the skin and mucous membrane. Formaldehyde is a protoplasmic toxic substance, which can bind to protein and cause severe respiratory irritation and edema, eye irritation and headache when inhaled at high concentration.

b. Sensitization: Direct contact with formaldehyde can cause allergic dermatitis, pigmentation, necrosis, and bronchial asthma can be induced when inhaled high concentrations of formaldehyde.

c. Mutagenic effects : High concentrations of formaldehyde are also a genotoxic substance. Experimental animals can cause nasopharyngeal tumors when inhaled at high concentrations in the laboratory.

d Outstanding performance: headache, dizziness, fatigue, nausea, vomiting, chest tightness, eye pain, sore throat, poor appetite, palpitations, insomnia, weight loss, loss of mind and autonomic disorders; long-term inhalation of pregnant women may cause fetal malformations, Even death, long-term inhalation of men can lead to male sperm deformity, death and so on.

Various artificial boards (particleboard, fiberboard, plywood, etc.) may contain formaldehyde because of the use of a urea-formaldehyde binder. The production of new furniture, the laying of walls and floors, the use of adhesives. Wherever a large amount of adhesive is used, there is always formaldehyde release. In addition, some chemical fiber carpets and paints also contain a certain amount of formaldehyde.

The floor is an indispensable part of the home decoration. Because the floor is beautiful and warm and durable, it has always been an indispensable part of the home decoration. However, for the floor, many people attach great importance to quality and environmental protection when purchasing the floor. However, it is difficult for ordinary consumers to thoroughly understand these factors.

After the concept of floor dust-free installation has been widely promoted, a new term has appeared on the floor, called “floor aldehyde removal installation”. It is literally understood to be able to eliminate formaldehyde, but for “floor aldehyde removal” is a The new promotional gimmick is really especially effective, but it is difficult to tell.

The basic idea of ​​aldehyde installation is that bamboo charcoal (activated carbon) adsorbs free formaldehyde, which is theoretically feasible, and the floor is three-point quality and seven-point installation. The environmental grade of domestic flooring has been upgraded from E1 to E0. Therefore, the installation of aldehydes is a good way to solve the problem of environmental protection. At present, a brand has begun to create the concept of aldehyde-free installation, which is to uniformly lay bamboo charcoal between the floor mat and the floor to absorb the free formaldehyde released from the floor. The effect of this method is absolutely achievable. But consumers will also worry, if the activated carbon is "filled up", what should be done. This problem is probably the first place where aldehyde removal is not satisfactory. But objectively speaking, the amount of formaldehyde released is a process of curve decline. As long as the room is kept ventilated, there is no need to worry too much about formaldehyde.

As for the wooden floor in addition to the aldehyde installation is a gimmick, I think the benevolent sees the wise and sees wisdom, but I think the appearance of the floor in addition to aldehyde installation is also good, because after all, there is still an effective installation. However, consumers should not rely too much on it. After installing the floor and keeping the room ventilated, be sure to prepare for the removal of formaldehyde again.
