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. Calcined talc powder is mainly used in plastics processing, rubber, coatings and inks, papermaking, ceramics, cosmetics, pharmaceutical excipients and other fields. Talc powder 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, where the preliminary treatment of wastewater in the utility process and the waste gas treatment process are included within the dataset boundary, 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 crushing of talc raw material, fine grinding in the mill, water addition and mixing, forming, calcination, secondary crushing, finished product and other process steps.
Activity Description
The production activities of this product include talc raw material crushing, mill fine crushing, water mixing, molding, calcination, secondary crushing, finished products and other processes.
Process Description
Calcined talc powder is an inorganic powder material obtained by crushing, grinding and high-temperature calcination of natural talc ore to remove crystal water. It appears as white or slightly yellow powder, odorless and tasteless, with low hardness (Mohs hardness 1-2), density of about 2.7-2.8g/cm³, and good lubricity, heat resistance and dispersibility. It is insoluble in water, acid (except hydrofluoric acid) and most organic solvents, has stable chemical properties, is resistant to acid and alkali, aging, and high temperature. It has excellent compatibility with polymer materials such as plastics, rubber, and coatings, and has certain reinforcing, toughening, and filling functions. Industrially, it is mainly used in the plastic processing field (as an inorganic filler and modifier to reduce production costs), the rubber industry (as a reinforcing filler); it is also used in the coating and ink industry, the paper industry (as a filler and sizing agent), and can also be used in ceramic glazes, cosmetic raw materials (to adjust skin feel), pharmaceutical excipients (anti-adhesive agents) and other fields.

Technology comment
The production of calcined talc powder uses talc as the main raw material. The talc is transported to a crusher for crushing, then sent by a conveyor belt to a mill for fine grinding to the required fineness. After ball milling, water is added to the talc powder through an automatic water addition system for mixing. The mixture is then processed by an eight-hole brick press to form talc powder green bricks. These green bricks are placed on kiln cars, which move through a tunnel kiln transfer system for calcination. After calcination, the bricks are crushed again with a crusher. Finally, talc powder with enhanced whiteness, uniform density, good gloss, and a smooth surface is obtained.
