Types and characteristics of snow melting agents
12 Nov,2024
Snow melting agent is a chemical substance used to melt road snow. According to different classification methods, snow melting agents can be classified into multiple types. The following are several common types of snow melting agents: 1. Classified by ingredients: Snow melting agents can be divided into chloride type snow melting agents and calcium chloride type snow melting agents. The main components of chloride type snow melting agents are magnesium chloride, sodium chloride, calcium chloride, etc., and the price is relatively low. Among them, chloride type snow melting agents such as a mixture of calcium chloride and sodium chloride can form chloride ions on the road surface in a short period of time, promote the melting of ice and snow, but have certain corrosiveness and are mainstream snow melting agent products on the market. However, long-term use can corrode roads and vehicles. Calcium chloride based snow melting agents that do not contain chlorine have less corrosive effect on roads and vehicles, but are more expensive. 2. Classified by usage: Snow melting agents can be divided into spreading type snow melting agents and spraying type snow melting agents. Spread type snow melting agents are mainly suitable for areas with heavy snow accumulation on roads, and can be evenly distributed on the road surface, but require more manpower and time. Spray type snow melting agents are suitable for larger areas such as airports and squares.

The role of calcium chloride in wastewater treatment
28 Jun,2024
The role of calcium chloride in wastewater treatment Calcium chloride plays an important role in sewage treatment, and its role is mainly reflected in the following aspects: 1. PH neutralization: Calcium chloride aqueous solution is acidic, so it can be used to neutralize sewage, pre adjust the acidic sewage pipeline network, thereby extending the service life of the pipeline network and saving investment costs. During this process, calcium chloride can effectively adjust the acidity and alkalinity of wastewater, providing suitable environmental conditions for subsequent wastewater treatment. 2. Sterilization and disinfection: Calcium chloride is a typical ionic halide, and its chloride ions dissolved in water have a bactericidal and disinfection effect. This property enables calcium chloride to effectively kill harmful bacteria in water, reduce water toxicity, and improve the safety of water quality. 3. Ion exchange: In the wastewater treatment process, the calcium ions in calcium chloride can replace the metal cations in the effluent, especially in the wastewater treatment process containing metal cations. This displacement effect can effectively remove toxic and harmful substances from water, reduce the damage of metal cations to the biochemical stage, and thus play a crucial pre-treatment role. 4. Filter aid effect: Calcium chloride can also be used as a filter aid in wastewater treatment, helping to improve filtration efficiency and further purify water quality. 5. Multi functional sewage treatment agent: Calcium chloride can be used as a common defluorinator, dephosphorizer, decolorizer, degreaser, etc. in sewage treatment. As a fundamental inorganic salt water treatment agent, calcium chloride combined with other efficient sewage treatment agents can not only reduce the cost of sewage treatment, but also achieve standard discharge of sewage. In summary, calcium chloride has various functions in wastewater treatment, including neutralization, sterilization, displacement, filtration assistance, and serving as a multifunctional wastewater treatment agent. These effects have made calcium chloride widely used in the field of sewage treatment, making important contributions to improving water quality and protecting the environment.
