preparation example Construction

[0097] The preparation method of described copper-organic ligand is:

[0098] Put BTC and copper nitrate containing polar groups in a polytetrafluoroethylene autoclave according to a certain molar ratio, add 2 / 3 of the volume of distilled water, then seal it, and conduct hydrothermal treatment at 80-120°C for 6-18 hours. The blue copper-organic ligand can be prepared.

[0099] In the present invention, the particle component B is a composite of copper-organic ligand and silicon dioxide.

[0100] In the present invention, the silicon dioxide may be commercially available or prepared.

[0101] (1) Dissolve the transition metal salt in an acidic solution such as hydrochloric acid, and stir at a certain temperature to completely dissolve it. The transition metal ion concentration is between 0.1 and 1mol / L, and the transition metal salt that can be used in this method can be a strong salt of an active metal, such as hydrochloride and sulfate of metals such as sodium, magnesium, a...

Abstract

The invention provides a ceramic filter composition capable of being used at high impacts. The ceramic filter composition at least comprises a fiber component A, a particle component B and a basic component C; the fiber component A is prepared from metal complex, a solvent, PVP and nano strontium titanate; the component B is prepared from a compound of copper-organic ligands and silicon dioxide; the basic component C is prepared from a ceramic matrix; the metal complex is the complex of metal and ligands, and the metal is selected from one or more of Bi, Cu, Ni, Ba and Ca. The ligands are selected from polar group containing aromatic carboxylic acid, and the polar group is nitryl or fluorine. The solvent is prepared from water and ethyl alcohol according to the volume ratio of 1:(3-8).

Description

technical field [0001] The invention relates to a filter material, in particular to a ceramic filter material which can be used under high temperature and high pressure. Background technique [0002] Mixing between two phases is a process that can occur naturally, but separating a two-phase or multi-phase mixture phase by phase is a process in which the enthalpy change is less than zero, so additional work is required. [0003] Filtration is a kind of separation technology, which mainly relies on filter materials to capture solid particles suspended in fluid. In the filtration process, there are three substances involved in the whole filtration process: dispersed particles, dispersed fluid and filter media. Filtration is a phase separation process that does not require additional work, so it can be widely used in various fields. According to the classic filtration effect, the common filtration mechanisms are mainly interception effect, inertial deposition effect, diffusion...
