UV curing equipment features

The UV curing device is an ultraviolet emitting device designed for the curing of photocurable coatings. It can cure coatings composed of prepolymers of free polymeric unsaturated groups, ethylene molecules that can dissolve them, and photosensitizing substances (photosensitizers), and commonly used are unsaturated polymers with added photosensitizers. Ester resin, unsaturated alkyd resin and modified epoxy resin and other photocurable coatings, this coating solid equipment has the following characteristics:

(2) Disadvantages

Considering the penetration of light energy, it is only applicable to transparent or translucent light-curing coatings, and other coatings cannot use this curing equipment. Low energy efficiency. Due to the short curing time, the input power of the UV bulb is large, and the output UV power is small, thus generating a large amount of thermal energy loss. Generally, only 20% of the ultraviolet light bulb power is converted to ultraviolet light, visible light accounts for 10%, infrared light and thermal energy account for 70%, and the general mercury lamp wall temperature can reach about 600°C.

The shape of the object to be coated is required to be simple, and it is not suitable for the solidification of the object to be painted which is liable to produce shadows. Although the aluminum plate can reflect more than 90% of the ultraviolet rays, the shadows are reduced to the minimum, but the shaded objects cannot be used.

Ultraviolet light bulbs emit intense ultraviolet rays, which can damage the skin and cause eye pain when directly irradiating the human body. Therefore, attention should be paid to this when designing an ultraviolet irradiation device, and the operator should wear protective glasses. In addition, ozone generated by ultraviolet light bulbs will corrode the surrounding equipment, and ozone also has adverse effects on the human respiratory system. Therefore, the design of the equipment should be considered.

Ultraviolet light bulbs generally have a service life of (1500-2000) hours, and the amount of ultraviolet light generated by the latter will decrease by (15-20)% in the later period. Therefore, regular cleaning of the reflectors is required.

(1) Advantages

Because of curing at room temperature, objects with poor heat resistance and objects with large heat capacity can be used. UV-curable coatings are essentially UV-cured and do not require direct heating. The infrared rays other than the ultraviolet rays emitted from the ultraviolet light bulb will increase the temperature of the curing chamber atmosphere and the temperature of the workpiece. In this case, the temperature of the workpiece can be controlled to 80° C. or less by adopting suitable measures. Therefore, paper, plastics, and wood can be cured in a short time. The curing of workpieces with large heat capacity is more energy-efficient.

Curing time is generally less than 20s, reducing the equipment footprint and energy consumption.

UV light irradiation equipment is relatively simple, investment and maintenance costs are cheap.
