Shell powder is a kind of wall coating, which uses high-quality deep-sea shells as the main raw materials and is developed through special high temperature calcination, grinding, catalysis and other high-tech processes. At the same time, unique inorganic nanotechnology is added to make the finished product appear dry powder. Main components and uses of shell powder
Its 95% main component is calcium carbonate, with a small amount of amino acids and polysaccharides. It can be used as high-grade materials for food, cosmetics and interior decoration. It is widely used in animal feed, food calcium source additives, jewelry processing, desiccants, etc. Shell powder biological coating is a new domestic decoration in recent years Interior wall paint , is one of the new applications of shell powder, and natural and environmental protection is its most important advantage.
1、 Formaldehyde
Source: Latex paint , wallpaper, paint, paint, floor, etc.
Hazards: The release period of formaldehyde is 3-15 years, which has the characteristics of long-term, latency and concealment, and has been identified by the World Health Organization as carcinogenic and deformed substances.
The National Cancer Institute of the United States released research results in 2009, and the death rate of blood cancer and lymphatic cancer among people who frequently exposed to formaldehyde was 37% higher. Formaldehyde ranks first in the national chemical priority control list. Data display:
Children with 0.06-0.07mg/m3mg/m3 will have slight asthma
0.1mg/m3 has peculiar smell and discomfort
0.5mg/m3 can stimulate eyes and cause tears
0.6mg/m3 throat discomfort and pain
30mg/m3 will cause immediate death
Not only that, formaldehyde can also lead to miscarriage of pregnant women, fetal malformations, ectopic pregnancy, anencephaly, etc.
For infants, long-term living in rooms containing formaldehyde can lead to chromosome abnormalities, leukemia, etc.
