1. (1) Safety and environmental protection: UV resin is a solvent-free resin, with a solid content of 100% that is completely converted into a film after exposure to light. The film is plump and bright, and there is no harmful gas emission during the curing process, which is helpful Improve the working environment and prevent air pollution. (2) High production efficiency: Basically not affected by the severe cold season, it can be cured quickly at room temperature. (3) Good film-forming performance: UV coating not only has high gloss, flat and smooth film, and has the properties of heat resistance, water resistance and scratch resistance. (4) Strong operability: Because the traditional curing mechanism of UV glazing is different, it is not limited by the coating time. The coated object will not be cured without ultraviolet light irradiation, and there is sufficient time to exhaust and remove Air bubbles, clean, well-maintained and unused resin can be used continuously, reducing waste and saving drug costs. (5) Brushing, spraying, roller coating, curtain coating and other processes can be used. The coating can be thick or thin, and can be applied several times for products that require film thickness.
2. UV resin curing mechanism The basic principle of UV coating is to use a certain wavelength of ultraviolet light to initiate a rapid curing reaction to form a transparent glossy coating on the surface of the object, which plays a role in beautifying decoration. Since the light curing speed is proportional to the intensity of light, in order to increase the light intensity, in addition to using high-energy ultraviolet lamps, the distance between the lamp and the work must be shortened to a minimum. If a low-energy light source is used, the lamp distance is best to be 6-8CM, and the closer the distance between the lamps, the better. If you use a high-energy high-pressure lamp, the irradiation distance should be 25-35CM. The high-energy lamp will increase the temperature and accelerate the curing speed. It should be comprehensively controlled during operation.
3. Precautions in UV coating operation: The light-curing resin is an independent material, so please pay attention to it during use.
(1) UV light curing resin cannot be mixed with other coatings.
(2) It is strictly forbidden to add thinner to dilute, if adding thinner will seriously affect the effect after curing, the fullness and hardness will not meet the requirements, and even blisters may occur.
(3) When using UV light-cured resin, it is best to use spraying. The film should not be too thick. Regardless of self-leveling or other methods, you should wait for the bubbles to drain before irradiating with the UV lamp.
(4) When using UV light curing resin, the working environment should be clean and dust-free operation, because it is not coated to prevent the film surface from being polluted.
(5) When using UV light curing resin, it is better to use high-energy light source for better effect.
(6) Regardless of the light source, you must pay attention to the timely update of the lamp. Light curing cannot be separated from the light. The stronger the light, the better the curing effect. The service life of the lamp is limited. Replace it in time if it exceeds the service life, otherwise Will affect the curing speed and effect.
