Embodiment Construction

[0006] see figure 1 , the preparation method of the nano-carbon liquid of the present invention, comprising:

[0007] The first step of material preparation: (1) Purify the water, and purify the water in the water production workshop to obtain deionized pure water with a pH value of 6.5-7.2 and a resistance value of 1MΩ-50MΩ. The resistance value is 18MΩ or more. (2) prepare the pole plate, select graphite carbon, require the purity of graphite carbon to be 99.99%, the ash content to be less than 100PPM, the fineness to be above 300 mesh, and the strength to be above 58mpa, and processed according to the requirements of the pole plate geometry;

[0008] Trial run before the second step of processing: use the processed graphite carbon plate as the positive plate, set metal negative plates on both sides, keep a certain gap between the positive plate and the two negative plates, and then put the prepared deionized Soak in pure water for 24 hours, turn on electricity, test whethe...

Abstract

A process for preparing the liquid containing carbon nanoparticles includes such steps as preparing deionized water, preparing graphite carbon plate as positive electrode, arranging two metal plates as negative electrode at both sides of graphite carbon plate, immersing them in said deionized water for 24 hr, applying a low voltage (3-35 v) for 7-10 days to obtain said liquid, laying aside for 24 hr, and ultrasonic treating for 1-2 hr. Its apparatus is composed of casing, circulating pump, supporting frame, plate electrode connecting rods, and positive and negative plate electrodes.

Description

technical field [0001] The invention relates to a method and equipment for preparing carbon liquid, in particular to a method for preparing nano-carbon liquid and its manufacturing equipment. Background technique [0002] There are many ways to prepare nano-carbon liquid by carbon oxidation, such as using concentrated nitric acid, concentrated sulfuric acid, nitro corrosion acid, potassium hypochlorite or potassium permanganate and other oxidants, as well as ozone oxidation, discharge oxidation or plasma discharge oxidation, electron ray irradiation, etc. method. None of the above-mentioned methods can directly obtain nano-carbon suspension, and many extremely cumbersome auxiliary processes are required, such as neutralizing acidity and removing harmful impurities such as metal particles in the carbon liquid. reunion. Preparation of nano-carbon liquid by the above method, its equipment is too complicated, and the process is too loaded down with trivial details Contents o...
