Embodiment 1

[0029] refer to figure 1 , the specific preparation method of the carbon-silicon composite material is as follows:

[0030] 1) First select graphite carbon with a purity of 99.9%, and use a calcined static pressure process to make a graphite carbon plate 220. The calcined static pressure process can achieve the best value for the purity and hardness of graphite, thereby producing the smallest particle size and the highest purity Highest carbon nanoparticle;

[0031] 2) Select silicon dioxide powder with a particle size range of 1-50nm to make a silicon dioxide plate 230;

[0032] 3) Place the graphite carbon plate 220 and the silicon dioxide plate 230 in the electrolytic reaction tank 210, connect the pulsating ion magnetic field stirring device 240 with a copper wire in series, and after adding pure water, feed the pulsating direct current into the electrolytic reaction tank 210 , to control its pulsating DC current 40A, voltage 12V;

[0033] 4) After the pH value in the e...

Abstract

The invention provides a carbon-silicon composite and a preparation method and system thereof. The preparation method of the carbon-silicon composite comprises the steps that graphite carbon with the purity being 99.9% is selected and made into a graphite carbon plate through calcination static-pressing technique; silicon dioxide powder meeting the particle size requirement is selected and made into a silicon dioxide plate; the graphite carbon plate and the silicon dioxide plate are placed in an electrolytic reaction tank, a pulse ion magnetic field stirring device is started, and pulse direct current is guided into the electrolytic reaction tank after purified water is added into the electrolytic reaction tank; and the reaction is stopped 10-12 days later after the pH value in the electrolytic reaction tank reaches 2.5. The preparation system at least comprises the electrolytic reaction tank, the graphite carbon plate, the silicon dioxide plate and the pulse ion magnetic field stirring device. The carbon-silicon composite is mainly prepared from graphite carbon, silicon dioxide and purified water. The preparation method has the advantages that operation is easy and convenient, the production cost is low, and large-scale production can be achieved easily. The preparation system has extremely high production practicability and is extremely economical.

Description

technical field [0001] The invention relates to a carbon-silicon composite material and a preparation method and system thereof, belonging to the technical field of soil improvement. Background technique [0002] my country is a big agricultural country, but not a strong one. The total area of ​​all kinds of saline-alkali land in the country is 1.487 billion mu (1 mu ≈ 667m 2 ), including 554 million mu of salinized soil, 673 million mu of residual salinized soil, and 260 million mu of potential salinized soil. Soil salinization refers to the phenomenon that the soil contains too much salt, which makes crops less productive or unable to grow. When the salt content of the soil surface exceeds 0.3%, the yield of crops will decrease significantly; when the salt content of the soil surface exceeds 0.6%, most plants cannot grow; when the salt content of the soil surface exceeds 1.0%, Only some plants specially adapted to saline soil can grow. Soil salinization is very harmful ...
