On the surface, dust does not directly injure people. However, this substance is actually composed of various phenols and hydrocarbons, and contains substances with strong carcinogenicity, especially wood powder with a particle size of less than 10 μm. It will directly enter people's lung tissue and damage the mucous membranes. As far as human health violations are concerned, they are reflected in the following major aspects:
(1) Systematic infringement
Long-term inhalation of higher concentrations of dust can cause systemic disease (pneumoconiosis) with diffuse, progressive fibrosis in the lungs; if inhaled toxic dust, it can be dissolved in the bronchial wall and be absorbed, and it can be caused by blood to all parts of the body. Systemic poisoning causes serious damage to the central nervous system, respiratory system, and digestive system.
(2) Local infringement
Contact or inhalation of dust first produces local irritative effects on the skin, cornea, mucous membranes, etc., and produces a series of lesions. If dust acts on the respiratory tract, it can cause hyperactivity of the nasal mucous membranes in the early stage, and the telangiectasias can form hypertrophic rhinitis for a long time. Finally, atrophic rhinitis is formed due to insufficient supply of mucosal nutrients. Can also form pharyngitis, laryngitis, trachea and bronchitis. Action on the skin, can form acne, folliculitis, pyoderma, such as lead dust immersed in the skin, there will be some small red spots, known as "lead rash."
(3) Carcinogenic induction
Intensive exposure to dust such as nickel, chromium, and chromate can cause lung cancer; contact with radioactive mineral dust can easily generate lung cancer; asbestos dust can cause skin cancer.
How to effectively control and eliminate dust during the renovation of a new house has become one of the most difficult problems faced by many businesses.
(1) Brush solid, block ground particles
Now that some of the new houses’ walls and walls are not in place due to paint, it is very easy to cause emptying, cracking, and dusting. This is the source of dust pollution.
In response to this, some home improvement companies have launched "adding a solid" program. Ground solidification is the surface curing agent, which is used for the curing treatment of the cement floor in the early stage of decoration. Ground solid can infiltrate the cement floor and block the loose particles on the ground, which facilitates the close combination of the decorative materials and the ground, effectively prevents the empty drum phenomenon of the floor tiles, and facilitates the floor cleaning.
(2) Wet wood cleaning
Before you move into a new home, ventilating the room is a must-have program for removing dust. In addition to cleaning the dust with a vacuum cleaner, wet cloth, etc., can wait until the dust has completely landed, and then spread some wet wood to the floor to clean. As sawdust has an adsorption effect, splashing with water will not dust, so that the dust will be cleared away.
(3) Doing dust protection
Usually in the wall part of the home renovation, the decoration workers first level with plaster, and then putty powder. In order to partially smooth the wall, after the putty powder is completely dried, it needs to be hand-polished with fine sandpaper.
During this process, there will be a large amount of material shedding, which is what we see as dust. During this period, regardless of workers or users, necessary protective measures must be taken.
(4) Use a dustless cutter
Nowadays, some companies in the industry have used dustless cutters to prevent the generation of dust through precise cutting. The built-in dust extraction technology in the cutter can also absorb a very small amount of dust generated to prevent the escape of dust and eliminate the dust to the utmost. When consumers purchase floors, the quality of floor coverings should also be considered.
The above is about the hazards of home dust pollution and the introduction of prevention and control measures. If you want to know more information, please contact us for the decoration information channel.
