UV curing system make use of a technology of instantaneous curing or drying. It normally lasts a couple of seconds to numerous hours and ultra-violet beams are applied on resins such as photo resists, ink, adhesives, and coatings to cause a photopolymerization reaction. The technology was initially used around forty years ago to cure ply-woods used in buildings. Since then, it has been developed and used in various fields.
There are many features and benefits of this technology compared to others. This article highlights and discusses some of them. This method has the advantage of happening in seconds, hence it is highly time efficient. The reaction changes a monomer compound which is liquid into a polymer which is a solid in seconds. The method is also very environmental friendly because the whole material is primarily cured using solvent-free photopolymerization. It fulfills most requirements by environmental bodies.
The procedure takes a short period rendering it possible to control temperature rises on the target object. This ability to control rise in temperature, makes this technology to find a lot of applications in heat-sensitive electronics. It could also be used on many forms of materials with diverse surface hardness and gloss.
The substance that is cured through this technology is called ultra-violet curable resin. The resin comprises an oligomer, photopolymerization initiator, monomer, and various additives such as fillers, stabilizers, and pigments. Monomers are organic substances that get polymerized and turned into bigger molecules of polymers to form plastics. Oligomers are materials that have reacted into monomers already. They react in a similar manner as monomers to form plastics too.
Both oligomers and monomers do not produce a polymerization reaction easily hence they must be combined with the photopolymerization initiator to initiate the reaction. The initiator gets excited when it absorbs the ultraviolet light to initiate the reactions. The resultant product is a high gloss finish such as the one found on guitars, vehicles, or some pieces of furniture. The finish is very durable and tough. It does not peel off easily.
Curing systems are an efficient way of drying optical components. The systems have windows and doors. The safety doors function to guarantee safety to users by halting all operations of the units when the main entry is unlocked. Viewing windows filter all UV rays stopping them from reaching device operators. They also encompass turntables that allow for curing through 360 degrees. The ultra-violet reflectors and lamps make sure that optical components get totally exposed for complete drying.
These systems may be categorized by mode into separated solidifying dehumidification and solidifying dehumidification. Frequency converters are used to regulate the wind rate within the solidifying dehumidification. Regulation of humidity and temperature is an automatic process. This helps to reduce errors that may be introduced by human inconsistencies. They are structurally designed in a manner so as to endure high temperature, airflow, and humidity.
Modern UV curing system are highly advanced. Their prices have gone down because of enhanced technology used in making them and lowered costs of production. They also appear in various shapes, colors, sizes, and are constructed from many different materials.
