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. The calcium-zinc composite stabilizer is used as the most widely applied non-toxic PVC stabilizer, commonly used in food packaging, medical devices, wire and cable compounds, environmentally friendly plastic products, etc. This dataset includes the main raw and auxiliary materials, energy, waste and air emissions of the production process, where the waste gas treatment process is included within the dataset boundary, and 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 raw material pretreatment, melt mixing, formulation adjustment, molding and other process steps.
Activity Description
The production activities of this product include raw material pretreatment, melt mixing, formula adjustment, molding and other processes.
Process Description
Calcium-zinc composite stabilizer is an environmentally friendly heat stabilizer composed of calcium stearate and zinc stearate as core ingredients, and auxiliary ingredients such as lubricants, antioxidants, chelating agents, etc. It mostly appears as white powder, granules or paste, and has no obvious odor. It is insoluble in water and easily dispersed in polymer materials such as polyvinyl chloride (PVC). It has excellent compatibility with resins. It has stable chemical properties, good heat resistance and weather resistance. It can effectively inhibit the degradation and discoloration of PVC during high-temperature processing. It does not contain heavy metals such as lead and cadmium, and complies with environmental protection and safety standards. It is mainly used in PVC processing (as an environmentally friendly heat stabilizer, especially suitable for products with strict requirements for environmental protection and no heavy metals) and the rubber industry (as a rubber vulcanization aid); it is also used in coatings and adhesives, and modification of plastic products. It can also be used in fields with higher safety requirements such as medical-grade PVC products and packaging materials.

Technology comment
To increase the fluidity of the raw materials, polyethylene wax and paraffin wax are placed into the mixer as lubricants; they must be heated to a molten state, and the mixer is activated to stir evenly. Stearic acid is then added, and after it becomes liquid, calcium stearate and zinc stearate are introduced. After thorough mixing, zeolite, calcium carbonate, etc. can be optionally added according to the required formulation. Once uniformly mixed, the material is conveyed through a trough into a slicer to be cut into flake products, or it is pulverized using a crusher to obtain powdered products.
