1. In terms of policies and regulations: The regulations and policies in the coating industry still have limited reflection on the concept of environmental protection, and some of the currently implemented regulations are far out of date.
2. In terms of technological innovation: Many small and medium-sized coating manufacturers still have certain obstacles in mastering and developing water-based technology. However, these conditions have been gradually improved, and more and more domestic companies are developing water-based technologies. The production and R&D capabilities of water-based coatings have reached a level comparable to that of foreign companies.
3. Application development: Due to people’s inherent concepts and the fact that many companies have reached a very proficient level in the construction of solvent-based coatings, many application companies have a relatively negative attitude towards the construction of water-based coatings, and Construction workers lack awareness of the hazards of solvent-based coatings to the human body and the environment.
4. Cost: The cost of water-based coatings is higher than that of traditional coatings, and the unit selling price is twice that of traditional coatings.
5. Public awareness: The general public’s awareness and recognition of water-based products and technologies is relatively low, and investment in popular education is limited.
Jia Feng, deputy director of the Publicity and Education Department of the Ministry of Environmental Protection, said: "From the perspective of national policy makers, VOC should be controlled as an important environmental factor and the corresponding environmental standards should be improved. From a policy perspective Policies have made the reduction of VOC an important legal requirement."
Qian Borong, chief engineer of a chemical research institute, said: "The introduction of regulations and standards will play a great role in promoting our country's coating companies. . Not only does it increase corporate environmental awareness, but also, due to the requirements of new standards, companies must carry out technological innovation.”
Traditional coatings use organic solvents as diluents and contain a large amount of volatile organic compounds (VOC). , about 2.2 million tons of VOC are emitted into the air every year in our country, which is equivalent to the total air inhaled by 1.3 billion Chinese people for 16 consecutive hours, and is increasing at an average annual rate of 9%
The impact of traditional coatings on the atmospheric environment and human health. Traditional coatings use organic solvents as diluents and contain large amounts of volatile organic compounds (VOCs), such as benzene, toluene, ethylbenzene, formaldehyde, methanol, ethylene glycol and other harmful substances. These substances are harmful to the human body through inhalation or skin contact. Cause harm.
