Transmittance Tester | Acrylic Application
Acrylic has been discovered for more than 100 years. It is also called plexiglass or PMMA. The name is derived from English acrylic and the chemical name is polymethyl methacrylate. So far, we have found the existence of acrylic in many places, or if you don't pay attention to observe, you think it is just plastic or ordinary glass. This transparent material often needs to cooperate with the transmittance tester.
In today's acrylic technology, it has been used in many different fields, such as windows; soundproof doors and windows; light boxes; signs; train and car doors and windows; childcare boxes; aquariums; lampshades and screens. Let ’s talk about some of the uses of acrylic that everyone may not know. During the Second World War, the fighter and submarine fuselages and hull glass of many countries were made of acrylic, because acrylic is lighter than glass and resistant to pressure. In addition, in some large-scale underwater parks, the transparent tourist corridor that runs under the seabed is specially designed to allow tourists to watch various marine animals as if they were in the underwater world. In fact, the transparent material that separates the water from the corridor is also acrylic. In the case of the need to observe the external environment through acrylic for the windshield of the aircraft or the glass of the underwater tour corridor, there is a relatively standard requirement for the light transmittance of acrylic, which cannot be dealt with casually. At this time, the transmittance tester played its role.
Using a transmittance tester to detect the light transmittance of acrylic is a very convenient way to directly reflect the light transmittance standard of the tested product. For example, a specialty store has created a large acrylic advertising light box. In a conspicuous place, it hopes to attract more guests to the store at night. If the light transmittance of the acrylic light box is insufficient, it is difficult for friends who are far away to see that there is such a store, which will indirectly lose potential customers. Therefore, it is necessary to use a transmittance tester to test the light transmittance before installing the acrylic advertising light box. Only when it reaches the relevant standards can it be used. The purpose of this is to ensure that the function of the light box can be played. It takes the least effort to detect, so the transmittance tester is actually inextricably linked to the acrylic process.
Since acrylic is so widely used today, what are its advantages?
Advantage one: Acrylic has crystal-like transparency and clear vision. If it is dyed, it will have a good color development effect.
Advantage two: It has good surface hardness and high temperature resistance.
Advantage three: It has good processability and can be thermoformed or mechanically formed.
Advantage four: The light-transmitting properties are similar to glass, but the density is only half of the glass. The weight is lighter under the same volume; it is not fragile, even if it is destroyed, it will not form sharp fragments like glass.
Advantage five: Strong chemical stability, resistant to various chemicals.
In fact, the advantages of acrylic are so many that can't be listed out. The most important thing is that this transparent material is used in conjunction with the transmittance tester. Of course, Linshang transmittance tester is the most recommended light transmittance measurement equipment.
