Problems solved by technology

[0005] For automobile volatile organic compound (VOC) pollution, Europe, the United States, Japan, Russia and other countries have implemented mandatory management systems according to relevant standards, while my country has no mandatory standards and management measures
On March 1, 2012, GB / T "Guidelines for Air Quality Evaluation in Passenger Cars" has been implemented for one year. Although it is a recommended standard, it also lays the foundation for the introduction of mandatory VOC emission standards in China. It can be seen that low The era of VOC products will not be far away
However, this form is not suitable for the long-term high anti-corrosion automobile inner cavity. The position of the weld seam with accumulated water is easy to cause reverse emulsification, and the film is easy to be washed away, which cannot achieve a long-term anti-corrosion period.
At the same time, water-based anti-corrosion wax products will freeze irreversibly in winter, and then break the emulsion and cannot be used
Under low temperature environment, the volatilization speed of water-based products is extremely slow, and it is not easy to form a film
