Embodiment 1

[0025] Such as figure 1 The shown embodiment 1 is a nano-calcium carbonate emulsification cycle modification device, which is used in the emulsification cycle modification process of nano-calcium carbonate manufacturing enterprises. The device is provided with an emulsification tank 14, an emulsification machine 3 is installed above the emulsification tank, and the emulsification head 31 of the emulsification machine stretches in from the top of the emulsification tank and is fixed on the top of the emulsification tank. The shape of the entire emulsification tank is a cylindrical stepped rod shape. The corresponding emulsification head is the upper section of the ladder rod, and the others are the lower section. The diameter of the upper section is smaller than that of the lower section, that is, the location of the emulsification head is the position with the smallest diameter of the emulsification tank. The top of the emulsification tank is slightly curved. The left side of ...

Abstract

The invention discloses a nanometer calcium carbonate emulsification circulation modification apparatus, which comprises an emulsifying pot and an emulsifying machine and comprises a circulating pipe.The emulsifying machine is arranged at the top of the emulsifying pot; an emulsifying head of the emulsifying machine extends downwards into the emulsifying pot and is located at the upmost end inside the emulsifying pot; the emulsifying pot is provided with two openings, which are connected to an upper end opening and a lower end opening of the circulating pipe; the circulating pipe is providedwith a pump; and the upper end opening of the circulating pipe is higher than the downmost end of the emulsifying head. Based on the apparatus, the invention further provides a nanometer calcium carbonate emulsification modification method, which adopts the nanometer calcium carbonate emulsification circulation modification apparatus. The method can emulsify a nanometer calcium carbonate thick liquid in a high-quality efficient manner, and is saved in energy consumption and reduced in production cost.

Description

technical field [0001] The invention belongs to the field of calcium carbonate industry, in particular to a nano-calcium carbonate emulsification cycle modification device and a method for applying the device to carry out nano-calcium carbonate emulsification modification. Background technique [0002] When nano-calcium carbonate acts directly on the organic medium, there are two defects: one is the agglomeration of nano-calcium carbonate powder caused by electrostatic interaction, hydrogen bond, etc.; the other is that nano-calcium carbonate is a hydrophilic inorganic compound, and its surface has hydrophilic The strong hydroxyl group is strongly alkaline, which makes its affinity with the polymer worse, and it is easy to form aggregates, resulting in uneven dispersion in the polymer, resulting in interface defects between the two materials, and the direct application effect is not good. . Therefore, it is necessary to modify the surface of nano-calcium carbonate to reduce...
