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. Zinc stearate is widely used in plastics processing, rubber, coatings and adhesives, food, cosmetics, building materials and other fields. Zinc 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 zinc stearate is C36H70ZnO4, CAS number 557-05-1. It is usually a white light powder, odorless and tasteless, smooth to the touch, insoluble in water, ethanol, ether, and easily soluble in hot aromatic hydrocarbons, fatty acids and other organic solvents. It has stable chemical properties and excellent heat resistance. It gradually decomposes when heated to above 200°C. It has excellent lubricity, mold release and dispersibility, and has a certain degree of transparency. It has good compatibility with plastics, rubber, coatings and other materials. Industrially, it is mainly used in the plastic processing field (as a lubricant, release agent and heat stabilizer, especially suitable for transparent products without affecting product transparency), the rubber industry (as an activator and release agent for rubber vulcanization accelerators); it is also used in coatings and inks (as a flattening agent, dispersant), cosmetics industry (as an emollient, talcum powder raw material), and can also be used in powder metallurgy (lubricant), food packaging materials (compliance additives) and other fields, especially for products that require transparency.

Technology comment
The melting method is the core mainstream technology for the production of zinc stearate. It is produced by reacting stearic acid and zinc oxide under molten conditions. The product has good dispersion and excellent thermal stability. It accounts for more than 80% of the domestic zinc stearate market. This data set represents this mainstream technology: using stearic acid and zinc oxide 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.
