Problems solved by technology

The amount of defoamer added cannot be controlled, and during the dispersion process, as the dispersion time prolongs, the defoamer is easy to volatilize, and the defoaming effect is poor. The defoaming effect is greatly reduced

Abstract

The invention discloses a sand mill capable of automatically adding an antifoaming agent and automatically testing a dispersion effect. The sand mill comprises a ceramic grinding barrel, a CNT (carbon nanotube) conductive paste, an antifoaming agent storage tank, a dispersion effect tester and an online viscosity tester, wherein serpentine circulating water pipes wind uniformly around the periphery of the side wall of the ceramic grinding barrel; the ceramic grinding barrel is filled with the CNT conductive paste, and a liquid level sensor and a temperature sensor are arranged in the ceramic grinding barrel; the antifoaming agent storage tank is arranged above the ceramic grinding barrel; the dispersion effect tester comprises an electrode a, an electrode b and a resistance instrument; the online viscosity tester is arranged above the ceramic grinding barrel and comprises a rotor extending into the CNT conductive paste. The sand mill can automatically add the antifoaming agent in a dispersion process and can automatically determine the adding quantity of the antifoaming agent according to the liquid level and the temperature of the CNT conductive paste. Besides, the CNT conductive paste dispersion effect and stirring time nodes can be judged accurately and effectively, and excessive stirring is avoided.

Description

technical field [0001] This application relates to an auxiliary inspection device in the production process of carbon nanotube slurry, especially a sand mill that can automatically add defoamers and automatically test the dispersion effect. Background technique [0002] As a one-dimensional nanomaterial, carbon nanotubes are light in weight, perfectly connected in a hexagonal structure, and have many unusual mechanical, electrical, and chemical properties. [0003] Carbon nanotubes have good mechanical properties. The tensile strength of CNTs reaches 50-200GPa, which is 100 times that of steel, but the density is only 1 / 6 of steel, which is at least an order of magnitude higher than that of conventional graphite fibers; its elastic modulus can reach 1TPa , equivalent to the modulus of elasticity of diamond, about 5 times that of steel. For carbon nanotubes with a single-walled ideal structure, the tensile strength is about 800 GPa. Although the structure of carbon nanotube...
