As the Year of the Snake approaches, Tongzhou District is preparing for its annual fireworks sales, which will begin on February 5, 2013, coinciding with the Lunar New Year. With the start of sales, the first batch of fireworks and firecrackers has already been stored in warehouses, triggering heightened security measures across the area. Recently, a reporter accompanied law enforcement officers from the Tongzhou District Security Supervision Bureau to inspect the storage facilities, gaining insight into the strict protocols in place.
According to the warehouse manager, over 9,000 boxes of fireworks and firecrackers have been stored since the beginning of the season. To ensure maximum safety, the facility has increased staffing to maintain 24-hour surveillance. An advanced infrared detection system has been installed on the outer walls, ensuring that even the smallest movement—like a bird flying by—will trigger an alarm. In addition, high-definition video surveillance systems are in place, allowing warehouse managers to monitor the premises remotely via computer. These systems are connected to both district and city-level security authorities, creating a multi-layered monitoring network.
At the entrance of each warehouse, electrostatic discharge devices are installed. Visitors must touch a stainless steel ball to eliminate static electricity before entering, reducing the risk of accidental ignition. All electronic devices, including mobile phones, are required to be turned off prior to entry, and only eight individuals are allowed inside at any given time. Temperature and humidity levels are continuously monitored using digital charts, as fluctuations can increase the risk of spontaneous combustion in fireworks.
During a recent inspection, law enforcement officers unpacked and examined several boxes of fireworks and firecrackers. They confirmed that all products are managed through an integrated system, utilizing electronic tags to track their entire lifecycle—from production to sale. Each box contains a unique chip embedded in the packaging, which can be scanned using specialized equipment to retrieve detailed information such as the product name, ingredients, manufacturing date, and current inventory status. This technology enables real-time tracking and ensures transparency throughout the supply chain.
On the same day, officials also conducted a thorough check of the warehouses, verifying compliance with regulations regarding the types, quantities, and storage conditions of fireworks. They assessed ventilation, stacking practices, and overall safety measures. Additionally, they reviewed the surrounding environment, security infrastructure, personnel training, and emergency response procedures to ensure everything is in order for the upcoming season.
With these comprehensive measures in place, Tongzhou District is working hard to guarantee the safe handling and distribution of fireworks during one of the most important holidays of the year.Sandwich Panel
What are the methods for judging the pros and cons of sandwich panel?
The material of the sandwich panel directly affects the later use. Sandwich panels are the main building materials for Prefabricated House and Steel Structure Warehouse. If you want to choose high-quality panels, you must have an understanding of their basic quality. There are many types of boards on the market, and their core materials, steel plates, adhesives, etc. are different, and the quality will also be affected. So how to judge its pros and cons?
check edge
Because the sandwich panel has several layers, it is difficult to judge its internal quality from the surface. Therefore, it is still necessary to observe its exposed edges first, and it is necessary to pay attention to whether its cross-section is clean and ensure that it is tight. If there are problems such as graying and impurities, then there must be problems in quality, so it is still necessary to do a good job of cross-sectional inspection.
Tap to hear the sound
If it is a relatively good board, you can simply tap it with your fingers. If the sound is a crisp metallic sound, then it is a relatively good board. The fire rating of the Rock Wool Sandwich Panel is Class A, and the fire rating of the polyurethane sandwich panel and Eps Sandwich Panel is B1.
Note the thickness
The thickness of the sandwich panel directly affects the long-term use in the later period. It is necessary to observe the substrate, peritoneum, etc., especially the thickness and quality of the coating, which we cannot ignore. It is necessary to choose a plate with a relatively thick coating and guaranteed quality. Generally, the thickness of the substrate should be about 0.4-0.8MM. If you see the real thing, you should also measure it. The thickness of the finished product is 50mm, 75mm, 100mm, 150mm. The bulk density of the core material is also an important link that affects the quality.
certificate
In fact, as long as it can cooperate with regular manufacturers, the plates sold by the manufacturers need to go through various inspections, and the quality must meet the regulations. Therefore, when purchasing, you can directly check whether it has a certificate of conformity. If you choose a plate from a regular manufacturer, you can not only enjoy a preferential price for direct sales from the manufacturer, but also enjoy good after-sales service.
Now there are many manufacturers supplying plates, and the market quotations and quality of each manufacturer are also different, so it is still necessary to do a good job of quality comparison and price measurement. It is suggested that when purchasing sandwich panels, one must pay attention to its specific quality, and compare the quality of the actual products in order to select high-quality panels.
