Since China's first subway was officially put into operation in Beijing in 1971, the subway has been an indispensable part of urban transportation, effectively solving the problem of excessive crowds caused by obvious agglomeration effects in big cities.
In the early days, there were no barriers between the subway platform area and the track area. Cases of delays in operations or even accidents due to factors such as people falling off the track or jumping off the platform were often reported in the news. As the urban population continues to increase, the subway has the characteristics of large passenger flow, short departure intervals, and short staying time at the station. Without any safety guarantee, a large number of crowded passengers are influx. If the subway platform does not have corresponding measures, Accidents falling into the track will greatly increase, and the piles will be shocking. In order to reduce the chance of such tragedies, in 2002, Guangzhou Metro Line 2 used an advanced screen door system in the subway for the first time. So far, subway screen doors have blossomed everywhere in the subways of major cities. Nowadays, subway screen door systems have almost become one of the standardized projects in subway construction.
The subway screen door is a high-tech product integrating materials, machinery, electronics and information science, including top boxes, fixed doors, sliding doors, emergency doors, load-bearing structures and thresholds. Among them, the toughened glass and stainless steel frame of the fixed door, and the toughened glass and stainless steel load-bearing structure of the sliding door are all bonded and sealed with high-performance sealant. Due to its high requirements for safety, subway screen door sealing and bonding often learn from traditional glass curtain wall bonding and sealing methods and adopt high-performance silicone sealant, which helps to ensure the safety of the screen door glue under the condition of toughened glass.
