What is a photopolymer?
Photopolymer is a polymer that heals or becomes solid when exposed to light. The word polymer means "many parts" and is defined as any material, synthetic or organic, consisting of small simple molecules chained together to form a larger molecule. Photopolymer photo indicates its sensitivity to light.
Photopolymer is maintained in a liquid state before use. After exposure to the light, the photopolymer is transformed into a firm condition. Light, or actinic radiation , can be emitted from a laser or lamp. Compounds that become solid after exposure to a certain radiation are known as radiation excreable; The photopolymer will only treat under the light, but other compounds can be similarly sensitive to microwave or thermal radiation. Usually, the photopolymer consists of a complex mixture of compounds rather than a single element. Photopolymer is used in conjunction with this process to make grades because it is cheaper thanReal rubber. This is achieved using a metal plate covered with a photopolymer film and the impression or printing of the desired image on a transparent surface. Photopolymer plate and image are exposed together in light, usually ultraviolet. The photopolymer is effectively "engraved" with a picture.
Photopolymer is also used to print type and art. The print plate made of a photo -volume can be used in letterpress and also has some advantages over traditional lead or magnesium plates. Photopolymer plates are easier to design than metal. In addition, they require less maintenance, they are more environmentally friendly because they are not etched by acids, and their surface is abrasion resistant and therefore will not wear out - causing longer life and more consistent type. The consumer can use the software to design a computer to set the type and also integrate any pictures or works of art and then send SKEnvrying a professional platelomaker.
Photopolymer Products is also used to produce photoresteners , which are patterned impressions such as those on the circuit board. These photoresteners are used in applications such as flat panel displays, printed or integrated circuits and microelectromechanical systems.
The photo of the photopolymer can also be used to produce largely larger models, as in rapid prototyping . Fast prototyping is an automated prototype building from a three -dimensional drawing. The three -dimensional CAD drawing is loaded on a computer and optically scanned and the ultraviolet laser beam solidifies two -dimensional photos of the photo -volume fluid in VAT according to the computer instructions. The stiff area is then covered with another layer of photopolymer liquids and the process is repeated until the three -dimensional prototype is completed.
