Embodiment 1

[0038] A petrographic analysis method of a powder sample, including six steps of sample mounting, rough grinding, fine grinding, polishing, erosion and petrographic analysis. Before the sample mounting, the powder sample is added to the sulfur that has been heated and melted in advance. After stirring evenly and standing for 3 minutes, the conventional sample mounting, rough grinding, fine grinding, polishing, etching and petrographic analysis steps are carried out; in this example, the mixing volume ratio of molten sulfur to powder sample is 0.1:1.

Embodiment 2

[0040] A petrographic analysis method for powder samples, including six steps of sample mounting, rough grinding, fine grinding, polishing, erosion and petrographic analysis. Before mounting the samples, the powder samples are added to the liquid resin with a curing agent, After stirring evenly, after standing still for 15 minutes, carry out conventional sample mounting, rough grinding, fine grinding, polishing, etching and petrographic analysis steps.

[0041] In this embodiment, the mixing volume ratio of the liquid resin with the curing agent and the powder sample is 0.5:1, the curing agent is ethylenediamine, and the liquid resin is epoxy resin; the mixing ratio of the curing agent and the liquid resin is 0.1:1.

[0042] Described sample mounting, coarse grinding, fine grinding, polishing, erosion and petrographic analysis, the specific steps are as follows:

[0043] (1) Mounting

[0044] Put the lump material into the mold, and import the liquid resin with curing agent,...

Embodiment 3

[0056] A petrographic analysis method for powder samples, including six steps of sample mounting, rough grinding, fine grinding, polishing, erosion and petrographic analysis. Before mounting the samples, the powder samples are added to the liquid resin with a curing agent, After stirring evenly, after standing for 10 minutes, carry out conventional sample mounting, coarse grinding, fine grinding, polishing, etching and petrographic analysis steps; in this embodiment, the mixing volume ratio of liquid resin with curing agent and powder sample 0.3:1, the curing agent is ethylenediamine, and the liquid resin is epoxy resin; the mixing ratio of the curing agent and liquid resin is 0.4:1.

[0057] Described sample mounting, coarse grinding, fine grinding, polishing, erosion and petrographic analysis, the specific steps are as follows:

[0058] (1) Mounting

[0059] Put the lump material into the mold, and introduce it into the liquid resin with curing agent. The curing agent is et...

Abstract

The invention discloses a method for analyzing lithofacies of powder samples, which comprises six steps of mounting, coarse grinding, fine grinding, polishing, etching and petrographic analysis, wherein powder samples are added into adhesives to be made into a bulk shape, the adhesives are used to adhere powder cement together to be made into the bulk shape, and powder is powder clinker or cement. The method for analyzing lithofacies of powder samples is substantially used to analyze the lithofacies of the powder samples, solves the problem in the prior art that just bulk materials are analyzed, and has the advantages that the method for analyzing lithofacies of powder samples is simple in operation and has great guiding significance to productive process.

Description

technical field [0001] The invention relates to a petrographic analysis method, in particular to a powder sample petrographic analysis method. Background technique [0002] Petrographic analysis is a method of analyzing the crystal optical properties, microstructure and phase type, content, shape, aggregation state, etc. of the phases in natural rocks or silicate materials using an optical microscope. Using petrographic methods to study the mineral composition and microstructure of cement clinker, through it, we can understand various problems that may arise in the production process, understand the mechanism of clinker formation process and hydration process, and have a good understanding of the subsequent cement production process and products. Quality improvement is of great significance. [0003] On March 25, 2015, the State Intellectual Property Office disclosed a piece of publication No. CN104458741A, titled a petrographic analysis method for cement clinker. The metho...
