In this ESD work, additional light scattering agent has been added during the production process of a normal acrylic. The added agent is a tiny inorganic particle. This particle make the light scattered in every direction and not only in the direction of the light beam. The ESD sign can be seen in a perpendicular direction to the light source. This is a new possibility and a major advantage against a normal acrylic. This newly created ESD process has been already patented “Thai Patent, submission no.0701001860, 18 April 2007”. This picture shows the Construction of ESD on the Advertisement media. An ESD plate surface is smooth and easy to attach an advertisement media. A scratch on an ESD plate will not cause a black spot on the sign. This is one of a major advantage against a current advertisements acrylics sign With ESD one can use both plate surface for the display.
A normal acrylic sign is built from a white acrylic with a painted color it give a good impression during the day. However during the night in order to illuminate the sign, a lot of light bulk are required which result in a high electric energy consumption. ESWA is created with the focus to due with this problem. The ESWA is a new white acrylic with a new mixture of different type of white pigments With the new mixture ESWA has less opacity and has double lightness against a typical white acrylic plate. Additional advantage of ESWA is their better mechanical strength. Comparison between ESWA and a normal white acrylic plate. For the same brightness ESWA required only two 16 watt fluorescence lamp. A normal white acrylic required three of them with even less brightness. At the end with the used of ESWA the energy consumption is reduced approximately by 33%. The ESWA work has been already patented “Thai Petty Patent, submission no.0803000578, 22 April 2008”. This ESD and ESWA research works are a co-operation projects between Rajamangala University of Technology Thanyaburi and Pan Asia Industrial Co.,Ltd with the funding from The Thailand Research Fund and National Innovation Agency
