Bus arson incident exposes bus safety inspection board
On the morning of the 15th, bus No. 656 of Xiamen Road headed to Caitang station. An old man under the vehicle suddenly used alcohol to set fire and threatened with murder. Afterwards, the naked flame was extinguished and passengers pushed and burned during the evacuation process. This is a common case of public safety in public transportation: Just as many bus explosions in the past, all actors ran their anger on innocent people to vent their anger. As a public transport with a high traffic flow, buses will cause serious casualties and property losses in the event of a malignant incident such as an explosion. However, compared with the stringent security inspections such as subways, trains and airplanes, buses are open to letting themselves drift, making buses very easy to become a high risk area for security risks. As the easiest and quickest means of transportation, there are numerous bus lines, complex lines, complicated passengers, and large mobility. There is no relatively closed operating environment and it is difficult to set up artificial safety supervision links. However, unavailability does not mean that it cannot be done. In this regard, some attempts have also been made in various places. For example, Xiamen takes the safety staff to follow all the buses and follow-up measures; Urumqi adds a full-time security inspection staff to each BRT platform; Chengdu There are hand-held liquid detectors at the entrances to the stations of the 2nd Ring Road Bus Rapid Transit. At the same time, temporary spot checks and spot checks on bus safety have also been stepped up in some places to facilitate the timely elimination of hidden dangers. However, it is not difficult to see that there are still many loopholes in these measures and there is no way to exercise full control and seamless control. To solve bus safety loopholes, we need to start from various aspects. First, we must improve the safety inspections at the pit stops, and implement compulsory safety supervision like subways and trains. Second, we must increase the number of safety guards for buses. It is necessary to conduct prevention and control of key personnel, but also to discover abnormal conditions on the vehicle in time. Third, it is necessary to increase the provision of automatic detection equipment for vehicles, especially small-scale security inspection equipment applicable to bus systems, and to strengthen the technology. Short board can discover hidden troubles and seedlings in time. A large number of facts indicate that the application of security technology can play a fundamental and critical role in ensuring the safety of public transportation. “Human Defence + Technical Defence†is the two major means to ensure the safety of public transportation. While strengthening technology prevention and increasing safety supervision staff, the key is to establish and nurture public safety awareness, safeguard and safeguard from the height of social governance transformation. Individual rights, timely elimination of various safety hazards, efforts to build a civilized, harmonious and tolerant society, elimination of widespread anger and hatred in society, can fundamentally ensure the safety of public transport, and extreme examples of bus arson can only be fundamental. Get guarded and put an end to it. Water-assisted injection molding: Water-assisted injection molding technology is an advanced injection molding process in which part of the melt is injected into the mold cavity and high-pressure water is injected into the melt through the equipment to finally shape the workpiece.
Due to the incompressibility of water, the water front creates a solid interface, squeezing the inner wall of the product into a cavity, and the water front also acts as a rapid cooling. Therefore, the water supplement has many advantages over the gas supplement. Research and application show that the water supplement can produce thinner and more uniform cavity wall, and the inner surface of the flow channel is very smooth. Especially for thick wall workpiece, the cooling time can be greatly reduced compared with gas auxiliary.

High gloss injection molding: Highlights the basic process of injection molding is prior to injection molding, through the use of high temperature and high pressure steam will mould surface rapidly warming, the forming die cavity surface temperature of resin plastic glass transition temperature (Tg) above, then the plasticizing good plastic melt into the closed mold cavity, the injection stage, mold temperature by high temperature and high pressure steam remains the same, When the injection is finished, the air supply is stopped, and the water vapor in the pipe is blown clean by air pressure of the air pipe. After that, the cooling water is injected to make the mold temperature drop rapidly until the mold is cooled and the product is removed by opening the mold
