A kind more than 700, power is by 100w-25kw.UV, which is solidificated in English, claims UV Curing or UV Coating, UV curing to be light
Chemical reaction, i.e. the UV radiation curables material of liquid are irradiated through being printed or applied to stock or workpiece surface through UV light
Realize the process of hardening, UV curings are similar to traditional drying process, but principle is different, and traditional drying is typically by means of coating
The volatilization of solvent in material and form hardening, and UV curing crosslinking then solvent-free volatilization.Since UV curings have, speed is fast, the period
The characteristics of short, efficient so that it has been widely used in the industry.
In general, UV power source internals other than power device, be additionally provided with transformer, capacitance, etc. heating devices, it is whole to generate heat
Amount is very big, and to ensure that heat dissipation is abundant, general housing volume is larger, and cost is also higher, and it is more inconvenient to use.
