Problems solved by technology

[0004] However, for the Xinjiang region, which is located in the northwest of China, the logistics is too far away, and the production cost of using inland raw materials is too high, so there is no market competitiveness

Embodiment Construction

[0019] Further detailed explanation through specific implementation mode below:

[0020] A kind of dry anti-seepage material among the present invention, the raw material composition of each embodiment and comparative example is shown in the following table:

[0021] serial number Experimental case coal gangue andalusite Binding agent 1 Example 1 70 10 20 2 Example 2 60 15 15 3 Example 3 80 8 12 4 Comparative example 1 50 30 20 5 Comparative example 2 90 5 5 6 Comparative example 3 70 10 20 7 Comparative example 4 70 10 20

[0022] The preparation method of the scheme of above-mentioned serial number 1-5 all comprises the following steps:

[0023] The first step is to select the local coal gangue in Xinjiang, remove the surface impurities, then crush it, grind it into fine powder, and pass the fine powder through a 325-mesh sieve;

[0024] In the second step, add andalusite fine powder and CA...

Abstract

The invention belongs to the field of anti-seepage materials, and specifically relates to a dry anti-seepage material. The dry anti-seepage material comprises the following components in parts by weight: 60 to 80 parts of coal gangue, 8 to 15 parts of andalusite and 15 to 23 parts of a binder, wherein the coal gangue is originated from the coal gangue in the area of Xinjiang in China. Meanwhile, the invention also discloses a preparation method for the dry anti-seepage material. Compared with a traditional dry anti-seepage material, the dry anti-seepage material provided by the invention is ananti-seepage material produced by modifying and processing a local main raw material capable of being utilized by a local enterprise in Xinjiang in terms of a process, so the production cost of the enterprise is greatly reduced, and the dry anti-seepage material provided by the invention is surely accepted by the market.

Description

technical field [0001] The proposal belongs to the field of anti-seepage materials, and specifically relates to a dry anti-seepage material and a preparation method thereof. Background technique [0002] During the operation of the aluminum electrolytic cell, due to the existence of pores in the cathode carbon block and the effect of the DC electric field, the electrolyte (or aluminum liquid) will leak under the cathode carbon block and continue to leak down along the cracks of the refractory bricks. The cathode refractory brick layer is gradually destroyed by the penetration of the molten electrolyte and the action of steam and loses its protective effect on the insulation brick layer below, resulting in damage to the aluminum electrolytic cell. Therefore, new refractory materials with good electrolyte permeability resistance are constantly being studied. At the end of the last century, a new type of refractory material for aluminum electrolytic cells-dry anti-seepage mate...
