Honeycomb ceramic materials for automotive exhaust gas treatment are often porous cordierite, with a geometry of 400 channels per square inch and a porous structure of 2-3 mm in the material, resulting in a high specific surface area of ​​0.2-0.3 m 2 /g. The atomic arrangement of noble metal platinum on the surface of the honeycomb ceramic support can be accurately determined by the EXAFS (extended X-ray absorption fine structure), which shows that the platinum atom forms a so-called sponge on the surface of the cordierite ceramic carrier. The crystals make the gas contact area in the catalytic converter average above 2000M 2 , and also make the gas molecules have a high probability of colliding with noble metal atoms in the catalytic converter to produce an effective catalyst conversion reaction. In addition to the development of different types of all-ceramic carriers, Inlay Semik High-tech Ceramics Co., Ltd. has catalytic honeycomb technology and production processes for the production of composite, alloyed and ceramic coatings.
In the event of a power outage, the emergency exit light displaying the exit sign must remain lit for an emergency period of 90 minutes and must remain lit continuously in working condition. Specially designed plastic and acrylic materials are lightweight, ABS material is strong, insulating, and not conductive. The letters "EXIT" can be printed on the transparent acrylic sheet and can be customized in green or red. Easy to install, simple to operate, can be hung on the wall or hung from the ceiling. The Emergency Exit Sign lamp suitable for different commercial buildings or public places such as hospitals, schools, subways, train stations, etc.
