Are coatings harmful to the human body, and what are the hazards of coatings to the human body?

Harmful, painters, a lot of people don't do it.

When it comes to coatings and inorganic pigments, many small partners should also have a vision, there are many raw materials related to this piece on the market, what are the coatings and inorganic pigments? What are the hazards of coatings to the human body? Let's take you to understand the detailed introduction of this piece, and also add relevant information about the hazards of coatings to human health.

What are the coatings and inorganic pigments?

1. At present, there are many coatings and inorganic pigments on the market, let's get to know them first. The so-called coating is brushed on the surface of the material with decorative design, maintenance and other effects, coatings are very common in daily life, such as polyurethane paint, nitro paint and its ultraviolet light solid reflection paint are all types of coatings. In summary, the viscous liquid made of epoxy resin, moisturizing emulsion, oil, etc., as the leading raw materials, and modified agents such as water or organic solutions, are all coatings.

2. The key to inorganic pigments refers to a kind of color paste made of some inorganic compounds, which has very good environmental protection characteristics. To sum up, as long as you see that titanium dioxide, iron blue, cadmium red, lithop powder, carbon black, iron oxide yellow, etc., which are made of various hydroxides, sulfides and sulfates as key raw materials in the packaging design, are all inorganic pigments.

What are the hazards of coatings to the human body?

1. Formaldehyde and benzene contained in the paint are very harmful to human health. Formaldehyde is invisible or touchable, but it has a strong smell, and long-term contact will affect the body's respiratory tract, tissues and other aspects. Moreover, the release period of formaldehyde and its substitution period is very long, up to 15 years, so we must buy big brands when buying coatings, and most of the formaldehyde content of big brands meets China's technical standards.

2. Benzene is also a colorless gas, but it has a very special fragrance, and the benzene content in the air is mainly in chemical raw materials such as coatings and super glue, and the body will cause certain damage to the central nervous system if inhaled for a long time. In addition, blood cells and red and white blood cells are gradually reduced, which can lead to aplastic anemia. In particular, the content of formaldehyde and benzene in some fake and shoddy coatings may exceed the standard, so you must pay attention to identification when buying.

1. Improper construction is easy to cause pollution According to experts, a large number of tests have proved that the purchase of coatings and the construction process have a great impact on the size of paint pollution.

Second, the construction of workers skills are not up to standard, the proportion of paint deployment is inappropriate. This often leads to the paint is not easy to dry, harmful gases are difficult to volatilize, and it is difficult to completely solve the problem even if it is ventilated for a long time. In a sense, the quality of the finishing depends on the coating, seven depends on the construction, if this is not good, even if the choice of high-quality paint, it is inevitable to endanger human health.

Paints. Coating, in China, the traditional name is paint. The so-called coating is a continuous film coated on the surface of the object to be protected or decorated, and can form a firm adhesion with the coated object, usually based on resin, oil, or emulsion, with or without adding pigments, fillers, adding corresponding additives, and a viscous liquid prepared with organic solvents or water.

Many owners will choose to paint latex paint when decorating, according to the needs of the market has also derived related industries, such as some people are engaged in paint production, some people are engaged in the painter industry, etc., as we all know that coatings contain benzene and other harmful substances, so is paint harmful to the body? Next, I will briefly introduce it to you.

1. Making coatings is harmful to the body. Paint is a major indoor pollution, containing organic compounds VOC, benzene, formaldehyde, lead, mercury and other harmful substances, of which benzene is identified as a carcinogen by the World Health Organization; Formaldehyde is a highly toxic substance; VOCs are defined as volatile organic compounds that are harmful in the sense of environmental protection, and long-term exposure to paints and coatings is prone to toxic encephalopathy (chronic painter's syndrome, etc.), and there is a higher risk of aplastic anemia, leukemia, nasopharyngeal carcinoma, tuberculosis, etc.

2. The hazards after the construction of the paint can not be ignored, and the ventilation should be carried out after the paint is painted indoors. When opening windows for ventilation, use air circulation to reduce the concentration of indoor pollutants, and the ventilation time should not be too short, and try to ventilate for more than one month. However, after the paint construction is completed, it is not possible to open the window immediately for ventilation, we need to wait until the paint is dry before ventilating, so as to avoid problems such as cracking of the paint film and dust sticking to the paint film.

3. If you want to paint indoors, you should try to choose environmentally friendly products. Coatings on the market can be divided into solvent-based coatings and water-based coatings, according to Qeeka Home experts, solvent-based coatings contain higher benzene content than water-based coatings, and it is best to choose water-based coatings. When we buy coatings, we also need to see whether the products are produced by regular manufacturers, and try to choose brand products with good reputation; It is also necessary to check the VOC and formaldehyde indicators of the coating.

Summary: Regarding whether making paint is harmful to the body, I will briefly introduce it to you here. I hope that after reading this article, you will be able to understand this. When we carry out interior decoration, we try to choose environmentally friendly paint products, and we also need to pay attention to ventilation after the coating application is completed.
