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 an automatic dispersing device for carbon nano tube conductive slurry. The automatic dispersing device comprises a ceramic grinding barrel; a controller with a timer therein is arranged on the bottom of the ceramic grinding barrel; a snakelike circulating water pipe is uniformly wound on the periphery of the side wall of the ceramic grinding barrel; the ceramic grinding barrel is filled with carbon nano tube conductive slurry, a liquid level sensor and a temperature sensor; a liquid outlet is formed in the bottom of a de-foaming agent storage tank; a solenoid valve and a flow sensor are arranged in the liquid outlet; a dispersing effect tester comprises an electrode a, an electrode b and a resistance meter; a distance between the electrode a and the electrode b is constant; and after being guided out through guide wires separately, the electrode a and the electrode b are connected to the resistance meter. The automatic dispersing machine can automatically add the de-foaming agent in a dispersing process, can give out a time node for dispersing and stirring the carbon nano tube slurry, and avoids excessive stirring.

Description

technical field [0001] The application relates to an auxiliary inspection device in the production process of carbon nanotube slurry, in particular to an automatic dispersion device for carbon nanotube conductive slurry. 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 nanotubes is similar to that...
