Who are the main suppliers of Calcium Chloride in China?
The main suppliers of Calcium Chloride in China are LIANYUNGANG RIFENG CALCIUM & MAGNESIUM CO., LTD, SHANDONG HAIHUA CO.,LTD, WEIFANG BAOSHENG CHEMICAL CO., LTD, WEIFANG TENOR CHEMICAL CO LTD, QINGDAO LIFENG CHEMICAL CO LTD and WEIFANG HAIZHIYUAN CHEMICAL INDUSTRY CO., LTD.
What is the production process of Calcium Chloride?
Calcium Chloride is typically produced through two main processes: the reaction of limestone (calcium carbonate) with hydrochloric acid or as a byproduct of the Solvay process, which produces soda ash. In both methods, the resulting solution is purified and concentrated, then crystallized or dried into solid form.
What are the packaging specifications for Calcium Chloride?
Calcium Chloride is commonly packaged in a variety of specifications depending on the application. Typical packaging includes 25 kg or 50 lb bags, 500 kg or 1,000 kg jumbo bags, and bulk containers. It is available in solid form as pellets, flakes, or powder, and in liquid form for industrial use.
What are the quality certification standards for Calcium Chloride?
Calcium Chloride typically adheres to quality standards such as ISO 9001 for general quality management and ISO 14001 for environmental management. Specific industry standards like NSF/ANSI 60 for water treatment chemicals and food-grade certifications ensure compliance with safety and purity requirements in respective applications.
What are the applications of Calcium Chloride?
Calcium Chloride is used in various applications including ice and dust control on roads, as a desiccant for drying gases, in concrete acceleration for construction, in water treatment, and as a food additive for firming agents. It's also used in refrigeration brines and agricultural practices.
What are the health risks associated with using Calcium Chloride?
Calcium Chloride can cause skin and eye irritation upon contact, and inhalation of dust may lead to respiratory issues. Ingestion can result in gastrointestinal irritation, nausea, or vomiting. Proper handling, use of protective gear, and adherence to safety guidelines can minimize these risks.
What are the advantages of Calcium Chloride compared to similar products?
Calcium Chloride offers superior moisture absorption, faster melting of ice, and lower freezing points compared to similar products like sodium chloride. It is more effective in de-icing, dust control, and as a desiccant. Its high solubility and hygroscopic properties make it ideal for various industrial applications.
What are the logistics and transportation costs for Calcium Chloride?
The logistics and transportation costs for Calcium Chloride vary depending on factors like shipping distance, packaging type (bulk or bags), and volume. Bulk shipments generally reduce costs, while smaller, packaged goods may incur higher fees. Additionally, its hygroscopic nature requires moisture-resistant packaging, influencing overall transportation expenses.
What are the storage conditions for Calcium Chloride?
Calcium Chloride should be stored in a cool, dry, and well-ventilated area. It must be kept in tightly sealed, moisture-resistant containers to prevent it from absorbing moisture from the air, as it is highly hygroscopic. Avoid storing near incompatible materials like strong acids or metals.
What are the market trends of Calcium Chloride?
The market trends for Calcium Chloride show increasing demand in de-icing, dust control, and oil drilling applications. Its use in water treatment and food industries is also growing. Market growth is driven by infrastructure development, especially in regions experiencing harsh winters, and the expanding industrial sector globally.
