Problems solved by technology

[0002] In the process of producing sponge titanium, the electrodes of the molten salt chlorination furnace used usually include refractory materials. Due to the difference in thermal expansion coefficient between refractory materials and graphite electrodes, gaps will gradually form under long-term high-temperature work, resulting in salt leakage. accidents, there is currently no effective way to avoid the phenomenon of salt leakage

preparation example Construction

[0020] The present invention also provides a preparation method of the anti-leakage cement. The preparation method includes mixing corundum, mullite, a water reducer and a binder.

[0021] According to the preparation method provided by the present invention, the mixing can adopt various methods in the field, for example, it can be mixed step by step or mixed together, and the order in which each component is added has no special influence on the performance of the obtained anti-seepage cement The consumption of each component can be adjusted according to actual needs, and in order to make the performance of the anti-leakage mortar better, preferably, the consumption of each component is such that the total weight of the obtained anti-leakage mortar is the basis, and the corundum content is 35-70% by weight, the content of the mullite is 5-15% by weight, the content of the water reducer is 0.01-0.2% by weight, the content of the binder is 20-50% by weight, further preferably, t...

Embodiment 1

[0031] This example is used to illustrate the preparation of the anti-leakage cement provided by the present invention.

[0032] First corundum, mullite and clay are ground to a particle size of 0.08mm. Based on the total weight of the anti-leakage cement to be prepared, each raw material is 45% by weight of corundum, 10% by weight of mullite, and 10% by weight of clay. , sodium tripolyphosphate 0.1% by weight, aluminum dihydrogen phosphate (bulk density is 1.35g / cm 3 ) and 34.9% by weight are evenly mixed, which is the anti-leakage cement for molten salt chlorination furnace.

Embodiment 2

[0034] This example is used to illustrate the preparation of the anti-leakage cement provided by the present invention.

[0035] First corundum and mullite are ground to a particle size of 0.08mm. Based on the total weight of the anti-leakage cement to be prepared, each raw material is prepared according to the weight of corundum 55%, mullite 10% by weight, sodium hexametaphosphate 0.1 % by weight, aluminum dihydrogen phosphate (bulk density is 1.35g / cm 3 ) and 34.9% by weight are evenly mixed, which is the anti-leakage cement for molten salt chlorination furnace.

Abstract

The invention provides an anti-seep cement gum for a molten-salt chlorination furnace as well as a preparation method and application of the gum. The anti-seep cement gum contains corundum, mullite, a water reducer and a binding agent. The anti-seep cement gum provided by the invention has the advantages of good molten salt erosion resistance, good sealing property and the like. The anti-seep cement gum provided by the invention is applied to the external part of combining a refractory matter around an electrode of the molten-salt chlorination furnace with a graphite electrode, and the molten salt which may leak is blocked, so that the salt leakage of the electrode of the molten-salt chlorination furnace can be effectively avoided, stable and continuous production of TiCl4 is ensured, and the anti-seep cement gum has good economic benefits and social benefits.

Description

technical field [0001] The invention belongs to the technical field of refractory materials, and in particular relates to an anti-leakage cement used in a molten salt chlorination furnace and a preparation method and application thereof. Background technique [0002] In the process of producing sponge titanium, the electrodes of the molten salt chlorination furnace used usually include refractory materials. Due to the difference in thermal expansion coefficient between refractory materials and graphite electrodes, gaps will gradually form under long-term high-temperature work, resulting in salt leakage. accident, there is no effective way to avoid the phenomenon of salt leakage at present. Contents of the invention [0003] The object of the present invention is to overcome the defects of the prior art and provide a fire-resistant and anti-leakage mortar with good corrosion resistance to molten salt and good sealing performance. [0004] In order to achieve the above obje...
