Problems solved by technology

[0003] Compared with natural mica, synthetic mica has a larger specificity and higher hardness. Because it is synthesized at high temperature, it cannot be softened by calcination and soaking like natural mica. Therefore, the traditional production method of natural synthetic mica powder is not suitable for synthetic mica powder. production
Due to the production method, it is impossible to produce synthetic mica powder whose product quality meets user requirements and is stable, thus limiting the application of synthetic mica powder

Embodiment 1

[0021] 1 ton of finely selected synthetic fluorophlogopite fragments with a particle size of +16 mesh were hydraulically crushed by a high-pressure water pump with a water pressure of 1.4 MPa to obtain material A with a particle size of 20 mesh, and the processing capacity of the hydraulic crushing was 100 kg / hour; Put material A into a stainless steel three-legged centrifuge with an outer diameter of 1 meter for centrifugal dehydration for 10 minutes, and the water content of material B obtained after dehydration is 25%; Material B is milled, the time of wheel grinding is 3 hours, and the time of polishing is 0.5 hours to obtain material C; then use a pump to pump material C into the classification pool, and measure the depth of material C to be 40cm. When the product requirement is 200 When the sedimentation velocity is 2cm / min, the sedimentation time is 20 minutes, and the particle size distribution is d 95 =138±5μm, d 90 =120±3μm, d 50 =63±2μm, d 10 =21±2μm, d 5 = 15±2...

Embodiment 2

[0023] 1 ton of finely selected synthetic fluorophlogopite fragments with a particle size of +16 mesh were hydraulically crushed by a high-pressure water pump with a water pressure of 1.8mpa to obtain material A with a particle size of 120 mesh, wherein the processing capacity of hydraulic crushing was 150 kg / hour; Put material A into a stainless steel three-legged centrifuge with an outer diameter of 1 meter for centrifugal dehydration for 15 minutes, and the water content of material B obtained after dehydration is 30%; use a wheel mill with a wheel mill gap of 0.8mm to Material B is milled, the time of wheel milling is 5 hours, and the time of polishing is 1.5 hours to obtain material C; then use a pump to pump material C into the classification pool, and measure the depth of material C to be 38cm. When the product requirement is 600 When the sedimentation velocity is 0.55cm / min, the sedimentation time is 69 minutes, and the particle size distribution is d 95 =51±3μm, d 90...

Abstract

A process for preparing mica powder from synthetic mica includes such steps as hydraulic breaking, deawtering, grinding to obtain sludge, classifying in classifying pools, and baking.

Description

technical field [0001] The present invention relates to a kind of preparation method of mica powder, relate in particular to a kind of synthetic mica flakes especially synthetic fluorine phlogopite fragments [KMg 3 (AlSi 3 o 10 ) F 2 ] as a preparation method of synthetic mica powder with a particle size of less than 200 mesh prepared by a wet method as raw material. Background technique [0002] Synthetic mica flakes are a kind of mica crystals artificially synthesized under high temperature conditions with a variety of chemical raw materials. Synthetic Fluorphlogopite [KMg 3 (AlSi 3 o 10 ) F 2 ] is synthesized at high temperature, so it does not contain hydroxyl groups and has better temperature resistance. Synthetic mica is widely used in electrical insulation and electronics industries due to its excellent electrical insulation properties, and a large number of synthetic mica fragments are also produced. In the past, synthetic mica fragments were mostly made int...
