The first new non chlorine snow melting agent used in Chang'an Street as corn straw extract

Yesterday, the reporter learned from the municipal appearance committee that for the first time, a new type of chlorine free snow melting agent has been applied in large scale in the city in the early snow, which can quickly melt snow in Tian'anmen Area and Chang'an Street Although the use of snowmelt brings convenience to people's travel, it may have an impact on the environment Therefore, the city has been more cautious about the use of snow melting agent The first use of non chlorine snow melting agent is extracted from corn straw The effect of snow melting and ice melting is basically the same as that of salt snow melting agent, but it has no pollution to the environment, plants and water After yesterday's spraying, the new snow melting agent can melt snow quickly, and the snow melting can be directly discharged through the sewage pipeline However, this kind of non chlorine snow melting agent is liquid, which can only be sprayed by sprinkler, the scope of operation is limited to a certain extent, and it can not be used in back streets, alleys and sidewalks It was also learned that the city also plans to provide snow and ice removal equipment in back streets and alleys, and require communities, streets, property departments and other departments to provide small snow removal machinery, so as to improve the efficiency of snow removal in alleys and communities - can the non chlorine snow melting agent be used? The price of the cheapest one ton of non chlorine snow melting agent is relatively high, and whether it can be "affordable" still faces a test According to the reporter, since 2007, the non chlorine snow melting agent has been approved for sale in Beijing market for the first time The non chlorine snow melting agent, also known as organic salt snow melting agent, can achieve the purpose of snow melting without polluting the environment, but the production cost of this snow melting agent is relatively high It is reported that the most expensive product is 15000 yuan per ton, and the cheapest one is about 10000 yuan per ton However, the production cost of the deicing agent containing chlorine is relatively low, and the manufacturer's quotation is generally about 1000 yuan per ton, with a price difference of more than 10 times In recent years, non chlorine snow melting agent products are only used in key areas such as airports Why do you encounter snow in the morning? Snowmelt agents do not make complaints about the first snow, so many citizens Tucao encounter the snow on the road when they go out in the morning Is it not enough for snowmelt agents? According to the municipal appearance Committee, the snow on the road seen by the early rising citizens was due to the fact that the snow melting agent had not yet begun to "take off" After the solid granular snow melting agent is scattered on the ground, it must be rolled by vehicles to release heat to play the role of snow melting However, since 4 a.m., there are few vehicles on the road, and the snow melting agent without rolling cannot fully melt the snow As a result, there is snow cover Yesterday, the city finally ushered in the first snowfall of this year The Municipal Urban Management
