We according to the national standard "QC T 484-1999 paint quality standards" on the vehicle's paint thickness of the minimum limit. What is the minimum limit, that is, put aside the quality of paint first talk about, that is, the car's paint can not be less than how many um is qualified. According to this standard, the minimum paint will be divided into the following reference standards:
First: for the cheapest entry-level economic mini-car (bare car prices less than 50,000) standard, the worst of its paint can not be less than 90um can be, we have this grade models of paint thickness requirements can be said Is relatively low Less than 90um as a paint cut corners.
Second: for more than 50,000 yuan for any model of the standard, this standard will increase some: the minimum can not be less than 120um (hard targets). Less than 120um as a paint cut corners.
Different models of the same parts, the thickness of the paint is different, different models with the thickness of the same part of the thickness:
① paint the thickness of the average greater than or equal to 120μm of the car, you can get the stars praise.
Note: the two standards are not the upper limit of the thickness of the requirements, theoretically, the paint the thicker the better, but we will not ignore those very strange numerical results, such as the price of 100,000, but with and more than one million models The same thickness of more than 200 um, which is not normal, where we will be specific to the specific analysis of the specific models, certainly not the implementation of the dogmas the thicker the better the logic.
② the maximum thickness of the difference between the thickness of less than or equal to 20μm car, you can get Star praise.
Note: the general depot coating process will be 4 or so, according to each process is less than or equal to 5μm as a reference standard, we set the maximum difference of 20μm.
