How to deal with the smelly cat's eye at the entrance?

In view of this smell, mild cases can be removed by natural ventilation for a period of time without treatment. If the smell is serious or unacceptable, you can contact the property or manufacturer to dissolve a reagent in perlite, which can effectively neutralize the smell.

The reason why this happens is related to the material filled in the door. For example, some materials contain perlite, active magnesium oxide (MgO), magnesium sulfate (MgSO4 _ 4 _ 4), flame retardant and other substances, which will volatilize after contacting with air, resulting in pungent smell in some entrance doors.

Although this smell is unpleasant, it will not have an impact on human health, and the production and manufacture also meet the national standards, so residents do not need to worry too much about the health hazards of this smell.

Noun explanation:

Door mirror is commonly known as cat's eye. Cat's eye is a small optical instrument installed on the door of a house. Because the light it refracts looks like the light emitted by Persian cat's eyes in the distance at night, it is nicknamed cat's eye.

Cat's eye, also known as door mirror, is a small optical instrument installed on the door of a house to facilitate residents to observe outdoor conditions. It has become a necessity for family safety.

It consists of a concave lens (objective lens) and a convex lens. The focal length of the objective lens is extremely short, which makes the people or things outside become an upright and reduced virtual image, which falls right in the focus of the eyepiece, and finally gets a reduced upright virtual image, which is just near the visual distance of the human eye, so that the situation outside the door can be clearly seen.
