Dispersion of precipitated calcium carbonate in glycol |
| abstract |
PURPOSE: The titled dispersion that is obtained by wet-crushing a precipitated calcium carbonate of specific dispersibility and particle sizes in a glycol, thus being used to stabilize the video tape running, because the particle size is uniform and the particle size distribution is sharp in glycol. n CONSTITUTION: The objective dispersion is obtained by wet-crushing (A) a precipitated calcium carbonate which has more than 0.1 micrometer of primary particle size D 1 calculated from the specific surface area S 1 determined by the BET method according to the equation: DX=60,000/2.7SX [DX is the average particle size in micrometer of the precipitated calcium carbonate calculated from the specific surface area SX determined by the BET method] and which satisfies the equation: R 1 =d 1 /D 1 ≤7 where R 1 is the ratio of d 1 /D 1 in which d 1 is 50% weight average particle size determined in water and D 1 is the average particle size in (B) glycol so that the ratio R 2 of the particle size D 1 to the primary particle size D 2 which is calculated from the specific surface area S 2 of the wet-crushed calcium carbonate satisfies equations: R 2 =D 1 /D 2 , 1<R 2 ≤10. n COPYRIGHT: (C)1987,JPO&Japio |
