For example, combs, plastics, paints, inks, pigments,
〇Light calcium vertical oxide is used as raw material for paper manufacturing, fertilizer, toothpaste, medicine, organic synthesis, cosmetics, filler, etc. Light calcium vertical oxide can be produced using JII method using general acid gasification method, lime soda method, soda method, etc. There are various shapes depending on the purpose, such as spindle shape, columnar shape, or needle shape. There is also activated light calcium carbonate whose surface is treated with a surfactant such as an aliphatic compound or an aromatic compound.

して広く用いられている。In addition, heavy calcium carbonate is usually manufactured by crushing and classifying limestone, and has a larger particle size than light calcium carbonate (General 1 to 5J), and has various crystal shapes and is irregular.
However, since the price is extremely low, it is widely used as an extender or filler.

。Calcium legate is used not only as a powder but also as a dispersion or slurry in an aqueous medium, for example, as a water-dispersible paint (emulsion paint) or as a slurry. When blending into coating agents for coated paper, charshun calcium is often dispersed in water or alkaline liquid in advance and used as a slurry.
Slurry products have also been commercialized for this purpose.

。One of the important things in handling the prepared calcium sulfate dispersion or slurry is that
The purpose is to maintain uniformly dispersed calcium oxide for a long period of time without causing changes over time such as agglomeration or solid-liquid separation.
特にスラリー品においては輸送上の経済性からも出来る
限り高鎖度の状態で固液分離が起らないことが極めて重
要である。Particularly in slurry products, it is extremely important to keep the degree of chain as high as possible so that solid-liquid separation does not occur from the viewpoint of economical transportation.

が悪くなり取扱いが困難であった。In conventional slurry preparation or slurry products, the solid content am is 35 to 40 even if easily dispersed calcium carbonate is used.
The limit is about 1% by weight, and if the concentration is more than 1IIIL, solid-liquid separation occurs during transportation or when left as it is, resulting in poor fluidity and difficulty in handling.
