    Abstract: 揮發性有機物 (Volatile Organic Compounds, VOCs),為一種環境的汙染源,其排放主要來自於塗料工業上溶劑的使用,現今工業上塗裝場所多在大氣中,若長久下來暴露於高VOCs濃度的場所可能危害人體。
    本實驗將分為兩部分討論:材料的部分:單體三官能基與單體二官能基調配而成,並且成功以無溶劑的型態調配UV固化溶液;噴塗的部分,實驗真空度為2×10-2 torr,藉由氣體壓力噴塗塗佈基板化妝瓶製作液相膜,接著在噴塗過程中使用高速攝影機觀察紀錄噴塗液體的分布情形,其後,將液相膜利用紫外光固化原理,放置UV燈底下照射使其固化,生成UV固化膜成品。
    ;Volatile Organic Compounds, VOCs, are environmental source of pollution, which mainly emitted by using solvent in industry of painting. Nowadays, the workplace of painting is most in atmosphere, if we exposure in this place, it may damage the human body.
    In order to reduce the solvent used in painting, in other words, reduce the contact with VOCs, this study established a vacuum polymer coating system to improve the spraying environment and use solvent-free coatings to move the process of industrial coating in the atmosphere to vacuum. Recycling and exhausting systems are established in the vacuum chamber to reduce the possibility of contact with the human body; Using UV-curable materials, it is desirable to achieve a solvent-free UV-curing solution, reducing the viscosity use in a vacuum spray system, atomizing by pressure , achieving a coating effect with a minimum spray amount and rapidly curing into a film. Complete the sample and establish the process of the vacuum spray system.
    The study began with improvements in the materials and environment in the coating industry. The research will discuss in two parts: Part of the material: monomer trifunctional and monomer difunctional. The UV curing solutions formulated in a solvent-free form; the sprayed part has an experimental vacuum of 2×10-2 torr, and the coating material sprayed with a nozzle by a pressure. The substrate cosmetic bottle be coated into a liquid film, and then uses a high-speed camera observe the distribution of the spray during the spraying process. Thereafter, the liquid film irradiated by UV lamp formed a UV curing film.
    This experiment compares the effects of different viscosity on adhesion and atomization, and UV curing film formation, observes the atomization phenomenon, solves the film formation problem, and successfully produces a film with a smooth and non-porous film surface. In the heat curing and UV process on the market, there are lower temperature and less energy consumption. The UV illumination time of the coating is 50 seconds, the hardness can reach 6H or more, and the adhesion is the highest level of 5B, which is friendly environment and high. Efficiency (no solvent), low VOCs emissions process.
