In recent years, local provincial and provincial governments have seized the important historical opportunity of building a national “big data†comprehensive pilot zone, and raised the development of “big data†industry to the strategic level of the province, accelerating and strengthening.
In the 21st century, a new round of scientific and technological revolutions and industrial changes triggered by information technology and the Internet have profoundly affected the progress of human progress. In recent years, local fire departments are catching up with the pace of the times, actively experimenting and exploring new technologies, and have accumulated rich experience and mechanisms, and have achieved great results and benefits.
The fire detection accuracy can be easily increased several times, and the fire rescue and rescue command system can realize one-click scheduling, enabling high-rise buildings to realize 24-hour fire supervision. New technologies such as big data, cloud computing and artificial intelligence are applied to the fire protection field, just like “the most The strong brain "runs with the same acceleration, and puts "wisdom wings" into the fire fighting work.
Under the overall information framework of the public health department of the Ministry of Fire, the local fire departments have comprehensively carried out information construction and application, and formed a new pattern of comprehensive, full-featured and full-process application informationization, showing a new trend of “hundred flowersâ€.
According to incomplete statistics, about 280 cities across the country have proposed or are building “smart citiesâ€, with a total investment of nearly one trillion yuan, relying on “smart cities†to build “smart firefightingâ€, intelligent command of strong combat power, and use of massive data. , predict risks, and establish early warning mechanisms.
Set up an "integrated platform", build a fire big data integrated business management service platform, integrate resources, build an integrated management service platform, and simultaneously aggregate data to achieve linkage and interoperability of various departments. For example, Yichang's five-level fire management grid makes it possible to convert countless information into fire big data and service fire protection. Le Bird developed the “Le Bird Cloud†fire-fighting IoT system to predict building fire risk.
The mystery of the industrial age is the division of labor, and the magic weapon of the Internet era is integration. Many regions have begun to provide standardized data interfaces, pooling and integrating the detachment information system and related department system information data, and centrally display and integrate these system data to realize information sharing. The analysis and judgment "accurately locate the weak links of fire hazards, analyze the quality of the bu team and individual work in the vertical direction, and compare the similar work between other units and individuals in the province.
In addition to relying on the overall planning of resources and the unified deployment of the corps, fire informationization and big data construction require more fire departments to develop intelligent applications in combination with the actual situation and problem requirements of the jurisdiction to solve their own unique problems. Applying big data, the management service aims at “four upgradesâ€, improving the fire prevention and control level of high-rise buildings, improving the comprehensive level of social fire protection, improving the refined level of fire fighting and rescue decisions, and improving the management level of fire safety.
Technology has enormous potential. Embracing big data, governments at all levels are open-minded, using the courage and determination to open the road and meet the water, and push forward the construction of fire information technology. In the new era, the fire department is taking the initiative to use big data to break through the fire work. "Providing the core driving force.
With the extensive application of fire information and big data construction, it is necessary to insert "wisdom wings" for fire protection work and promote the rapid development of fire protection.
Calcium Carbonate
According to the different production methods of calcium carbonate, calcium carbonate can be divided into Heavy Calcium Carbonate, light calcium carbonate, colloidal calcium carbonate and crystalline calcium carbonate. White solid, tasteless and odorless. There are two forms of amorphous and crystalline. The crystal type can be divided into orthorhombic crystal system and hexagonal crystal system, which are columnar or diamond-shaped.
Calcium carbonate is widely used in filling polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), acrylonitrile butadiene-styrene copolymer (ABS) and other resins. The addition of calcium carbonate has a certain effect on improving certain properties of plastic products and expanding their application range. In plastic processing, they can reduce resin shrinkage, improve rheology, and control viscosity. It can also play the following roles:
(1) Improve the dimensional stability of plastic products;
(2) Improve the hardness and rigidity of plastic products;
(3) Improve plastic processing performance;
(4) Improve the heat resistance of plastic products;
(5) Improve the astigmatism of plastics;
(6) It can make the product have some special properties;
(7) Reduce the cost of plastic products.
