The Central Meteorological Observatory predicts that there will be heavy snow in central and eastern Heilongjiang, eastern Jilin, and other areas today and tomorrow (November 17-18). Local blizzards or blizzards may cause disasters due to snow accumulation. This is the third rainy and snowy weather process in Northeast China since November. Which parts of China are most prone to snow disasters? What are the types and hazards of snow disasters? How to defend? Please keep this snow disaster encyclopedia.
These three major regions are most prone to snow disasters. Local areas can see snow cover throughout the month
In China, snow disasters have a wide range of impacts, with snow disasters occurring in both the north and south. From a regional perspective, snow disasters are mainly concentrated in three major snow covered areas, namely the Qinghai Tibet Plateau, northern Xinjiang, Inner Mongolia, and the Northeast region.
The statistical data of the average annual snow cover days in the past 30 years shows that the eastern part of Inner Mongolia, Heilongjiang and most of Jilin, as well as the northern part of Xinjiang, have the longest average visible snow cover time in China, with more than 50 days of snow cover in local areas in a year. Throughout the year, November to March of the following year is the period with the highest number of snow cover days in various parts of China. In December, except for South China, two-thirds of China's territory will experience snow cover. The number of snow cover days in eastern Inner Mongolia, Heilongjiang, most of Jilin, northern Xinjiang, and other places can reach over 25 days, with local snow cover even visible throughout the month.
Snow and snow disasters have a special name in pastoral areas - white disasters, which refer to the phenomenon of livestock being unable to eat normally due to the thick and long duration of snow cover, burying grass, and generally occurring from October to May of the following year. Among them, November and March and April are the most common, which can cause a large number of livestock to be frozen and starved to death and the collapse of sheds.
Snowstorms are usually caused by the combined influence of strong cold waves and southwest airflow. When a place experiences more than 10 millimeters of snowfall within 24 hours, with wind speeds of 18 meters/second or more, and temperatures falling below -5 ℃, a snowstorm is formed. The low visibility caused by snowstorms may cause airport flight delays, highway closures, and strong winds can also cause trees to break and houses to be damaged.
The snow disaster has brought serious harm to the national economy:
1. Transportation is obstructed, affecting logistics transportation and the supply of production and daily necessities.
2. Damage to infrastructure, affecting the normal operation of power, communication, and other systems.
3. Impact agricultural production, reduce crop yield and quality
4. It poses a threat to the safety of people's lives and property, especially for people traveling and living in mountainous areas
5. Increasing social burdens, such as medical assistance and post disaster reconstruction, requires a significant investment of manpower and resources.
Therefore, we need to strengthen monitoring and early warning, take timely measures, and minimize the impact of snow disasters on the national economy as much as possible
How to respond to a snow disaster? Please check this defense and self rescue guide
The snow disaster has a great impact on people's lives and agriculture and animal husbandry. FkhChem has specially summarized the defense and self rescue guidelines before, during, and after the arrival of a blizzard, to help you survive the winter safely.
Before the arrival of a blizzard, it is necessary to pay attention to meteorological warning and forecast information, as well as traffic information such as highway closures and airport delays, and adjust travel plans in a timely manner; Also, prepare sufficient food and water, and take measures to keep warm; To prevent snow from crushing the roof, it is necessary to stay in a sturdy house; If in pastoral areas, it is necessary to ensure sufficient feed as much as possible.
When a blizzard arrives, do not rush out to sweep the snow, try to stay indoors for heating, and pay attention to the correct use of equipment. If using coal, be careful to avoid carbon monoxide poisoning. If it is necessary to go out, be fully armed from head to toe, and pay attention to keeping your head and feet warm. When driving on snowy days, it is necessary to maintain a large distance between vehicles and reserve sufficient braking distance to avoid vehicle slipping. If the wind and snow are too heavy and the vehicle is trapped, it is also necessary to call for help in a timely manner in the car to avoid staying outside for too long and losing temperature.
If using a generator, please place it outdoors at least 20 feet away from home to avoid diseases or deaths caused by carbon monoxide.
After the end of a blizzard, the temperature is often still relatively low, the snow has not completely melted, and there may be a risk of road icing. When going out, it is still necessary to be cautious of slippery roads. If you fall, try to use your hands or elbows to support the ground as much as possible to avoid injuring important parts such as the head. In pastoral areas, herdsmen need to repair or rebuild sheds in a timely manner, and pay attention to feed supply to prevent livestock from losing weight.
Have you learned the above snow disaster tips and blizzard prevention guidelines? FkhChem reminds you to enhance disaster prevention awareness, master disaster prevention knowledge, and be able to self rescue at critical moments.

The CAS number (Chemical Abstracts Service number) is a unique identification number used to identify chemical substances. It is assigned and managed by the Chemical Abstracts Service. The main function of CAS numbers is to ensure accurate and unique identification of chemical substances globally.
The CAS number consists of three parts: prefix, hyphen, and suffix. Prefix is usually composed of 2-7 digits, used to identify the serial number of a chemical substance. Hyphens are used to separate prefixes and suffixes. A suffix is a number or letter used to distinguish different forms or isomers of the same chemical substance.
The CAS number has a fixed length of 9 digits and can identify millions of different chemical substances. Each chemical substance has a unique CAS number, which enables scientists, researchers, and engineers to accurately identify and retrieve relevant chemical information.
By querying and using CAS numbers, people can obtain various information related to chemical substances, including chemical formulas, structural formulas, physical properties, toxicity data, chemical reactions, and uses. CAS numbers are also commonly used for chemical labeling, safety data sheets (SDS), scientific literature citation, and communication.
In summary, CAS number is a globally recognized chemical substance identification number that provides convenience and guarantee for accurate and unique identification of chemical substances, promoting chemical research, product development, and safety management.

Prospects of sodium chlorate
Posted on Nov 09.2023
Prospects of sodium chlorate
![]()
Sodium chlorate, as an important chemical raw material, has a wide range of applications, including papermaking, water treatment, metallurgy, dyes, and so on. With the increasing awareness of environmental protection, the demand for energy and resource conservation, as well as environmentally friendly products, the market prospects of sodium chlorate are generally showing a good trend
On the one hand, with the development of the economy and the improvement of people's living standards, the development momentum of industries such as papermaking and water treatment is good, and the demand for sodium chlorate remains at a high level. On the other hand, with the development of new technologies and the rise of alternative products, the market size of sodium chlorate may be affected to some extent.
In the global sodium chlorate market, four companies dominate: Italy's Ica Chemicals Limited (a subsidiary of Akzo Nobel), Canada's ERCO, Canada's Canexus, and Finland's Kemira. China is one of the world's largest consumer markets, accounting for a considerable proportion of the total sodium chlorate market. There are about 18 domestic sodium chlorate enterprises, with a production capacity of 913000 tons in China, including 570000 tons of individual production units and 343000 tons of supporting production units.
However, due to the relatively sluggish downstream industry of sodium chlorate in recent years, the global demand for sodium chlorate has shown a decreasing trend. But in 2021, as pain is brought under control, the economy and industry recover, and the demand for sodium chlorate applications rebounds. At the same time, as demand continues to increase, the sodium chlorate market will move away from disorderly and low-priced competition, which is conducive to the long-term stable development of the industry
Overall, although the global demand for sodium chlorate has fluctuated, it shows good development prospects overall. In the future, the sodium chlorate market may be affected by environmental policies, the introduction of new technologies, and market competition, but overall, it will still maintain a stable growth trend.
