Ceramics, calcium carbonate, talc powder, sulfate, etc. are commonly used in the coating industry as fillers to improve the physical, chemical, or optical properties of the coating film.
White soil, talc powder, white ravioli, titanium pink powder, sulfate, calcium carbonate, etc. are commonly used in the papermaking industry as fillers to improve the opaque, smooth ink absorption of the paper.
Magnesium sulfate, gypsum, sodium sulfate, ammonium sulfate, glucose, etc. are commonly used in the leather industry as fillers so that the leather is full, elastic, and shallower.
In the pesticide industry, when processing the agent into powder, wettable powder, and particle agents, inert powder such as talc powder, clay, and diatomic soil often use as fillers.
