In the process of coating construction, the most influential factors are construction environment, coating process and curing process. Therefore, in order to achieve high quality coating effect, it is necessary to inspect and control the above three aspects.
(1) The construction environment mainly includes the temperature and humidity of the roll coating room, as well as the indoor ventilation cycle conditions.
(2) Coating technology mainly includes the viscosity of coatings on machine, the number of layers of coatings, the thickness of coatings, the speed ratio of rollers to production line and the quality of roll surface.
(3) Curing process mainly includes hot air circulation, hot air temperature, curing temperature curve setting and other factors.
