Description
This dataset is a market dataset representing the consumption market of the region. The dataset includes the transport of the product from the gate to the consumption end, and the transport service is calculated based on the transport situation of the product in the region. Calcium stearate is widely used in plastics processing, rubber, coatings and adhesives, food, cosmetics, building materials and other fields. Calcium stearate is modeled as a pure substance, and when modeling this substance the user needs to add a solvent of their choice in the model; this dataset includes the main raw and auxiliary materials, energy, waste and air emissions of the production process, while infrastructure such as production equipment manufacturing and plant construction is not included within the dataset boundary; the data inventory is formed by merging data from multiple sources; the production activity of this product includes feeding, reaction, discharge mixing, crushing and other process steps.
Activity Description
The production activities of this product include feeding, reaction, discharging, mixing, crushing and other processes.
Process Description
The chemical formula of calcium stearate is C36H70CaO4, CAS number 1592-23-0. It is usually a white fine powder, odorless and fluffy in texture. It is insoluble in water, ethanol, ether and other solvents, and can only be dispersed in hot water. It has stable chemical properties, is acid-resistant, alkali-resistant, and high-temperature resistant. It will not decompose until heated above 400°C. It has both lubricity and anti-adhesion properties, and has certain thermal stability. It has good compatibility with polymer materials such as resin and rubber. Industrially, it is mainly used in the field of plastic processing (as heat stabilizer, lubricant and release agent), rubber industry (as rubber softener and release agent); it is also used in coatings and adhesives (as anti-sedimentant, matting agent), food industry (as anti-caking agent), and can also be used in cosmetics (to adjust texture), feed additives (moisture-proof and anti-caking), building materials (water-proof additives) and other fields.

Technology comment
The melting method is the mainstream technology for the production of calcium stearate. It is produced through the reaction of stearic acid and calcium oxide in a molten state. The process has a high degree of continuity and the product purity is stable. It accounts for more than 85% of the domestic calcium stearate market. This data set represents this mainstream technology: using stearic acid and calcium hydroxide as raw materials, the production process is divided into main steps such as feeding, reaction, discharging, mixing, crushing and packaging:
1. Feeding: It is mainly divided into two processes: unpacking and pipeline feeding. Unpacking is performed in the feeding station. Powdered materials such as calcium hydroxide and zinc oxide will generate dust;
2. Reaction: The reactor is heated by a natural gas thermal oil furnace, heated to 130°C for about 4 hours, and a white molten product is obtained at the end of the reaction. The reaction process will produce dust and organic waste gas;
3. Discharge mixing: The reaction product enters the discharging cooling mixing system through a closed pipeline and uses a cooling water circulation system for indirect cooling. At the same time, the materials are initially crushed. This process will generate dust;
4. Crushing: The cooled material enters the crushing system through a closed pipeline to obtain the finished product.
