The positive effect of the proposed solutions is that:
1. Much easier discharging ink compositions of the bead mill, reducing the time of this operation, the operation itself takes place by gravity, does not require the use of vacuum, temperature decreases upload up to 80°C. All this is a direct consequence of increasing the fluidity of the ink composition as a result of entering into it aluminum salts.
2. Aluminium salts help to reduce adhesion of the composition to glass (glass beads) and the metal casing bead mill. As a result, the flow of product from the reactor when the discharge increases, and consistent with several parties accumulation of residual quantities of nespivshegosya from the reactor product does not occur.
3. Enter aluminum salts in the composition increases its mass and does not impair its main qualitative features as intermediate for oiling status is Bob either individually, neither the complex as a whole. On the contrary, the latter, in particular, is improved by reducing the negative impacts of water treatment processes sodium sulfite and using feeding. And the surface treated in this oiling skin acquires a certain water-repellent properties.
4. The required solutions of aluminum salts can be obtained in the same bead mill, where the production of the black ink composition. Therefore, no need to search their manufacturer and address associated with the purchase, delivery and storage issues.
