Some national heavy metal element content standards
Total lead-refers to the total content of lead and its compounds in the material factory (in terms of lead element content).
After treatment by acid digestion, the lead content is quantitatively determined with special equipment.
It can be seen from the above requirements that the current European standards are the most stringent, restricting 19 heavy metal elements.
This is from the year before last, from the previous 8 kinds of heavy metal elements restrictions have been tightened to 19 items.
Among the 19 elements, hexavalent chromium and organotin have the highest requirements for detection technology, equipment, and standard solutions, and they are also hard indicators to measure laboratory capabilities.
Normal laboratories can only detect up to 17 elements.
At present, there are about 5 laboratories that can do 19 tests and are accredited by HOKLAS and CNAS.
Standards for plasticizer limits in China and Europe
As for the limits of phthalates, the following table:
It can be seen from the above table that the restriction requirements of China, Europe and the United States are basically the same.
What I want to emphasize here is that our country’s requirements have been newly added in recent years and are required to be implemented on January 1, 2016.
Three aspects to control harmful substances in coatings
The control of harmful substances in coatings is mainly divided into the following aspects:
1.
The use of environmentally friendly paint means that the paint itself meets the requirements of relevant standards.
For each batch of coatings, there should be a test report of the relevant qualification laboratory.
2.
In the production process, ensure that the formulated paint meets the standard requirements.
This requires first to control the process, such as paying attention to whether the added substances, containers, agitators, and environmental cleanliness will introduce toxic and hazardous substances.
Finally, the samples were tested and proved to be qualified.
3.
When raw materials, auxiliary materials and batches change, they must be tested and verified before they can be used.
