Specific embodiment
For a further understanding of the present invention, the preferred embodiment of the invention is described below with reference to embodiment, still
It should be appreciated that these descriptions are only further explanation the features and advantages of the present invention, rather than to the claims in the present invention
Limitation.
The embodiment of the invention discloses a kind of solids of dry laser Particle Size Analyzer to wash material, comprising:
40~70wt% of barium sulfate；
30~60wt% of silica flour.
Solid provided by the present application wash material be primarily directed to the analysis sample carryover of dry laser Particle Size Analyzer in point
The cleaning of the positions such as analyzer pipeline, feed inlet and discharge port, since the analysis detection sample of analyzer is dry material, and dry powder
Material has the characteristics that light, density is low, is easy absorption and poor fluidity, is difficult to clean completely, as a result, using traditional material of washing
This application provides a kind of solids to wash material comprising barium sulfate solid powder and silica flour.The application is to the dry laser grain
Degree analyzer is not particularly limited, and is analyzer well known to those skilled in the art.
The barium sulfate powder specific gravity that the application uses is big, is not easy to adsorb, and has good mobility, is conducive to dry method and swashs
The cleaning of dry material in light Particle Size Analyzer.The quartz powder particles and barium sulfate are capable of forming good gradation, itself
Specific gravity is larger, is not easy to adsorb.
According to the present invention, the barium sulfate and the silica flour use suitable mass fraction, the solid that could make
Washing material has optimal cleaning effect.The content of the barium sulfate is 40wt%~70wt%, and the content of the silica flour is
30wt%~60wt%；The content of the barium sulfate is lower than 40wt%, then the solid obtained is washed the active force that material provides and reduced, washes
Wash effect variation；The content of the barium sulfate is higher than 70wt%, and the barium sulfate can be to the pipeline of dry laser Particle Size Analyzer
It causes to wear, influences precision and the service life of instrument.Preferably, the content of the barium sulfate is 48~65wt%, more excellent
It is selected as 50~60wt%.The content of the silica flour is excessive or the very few gradation that also will affect solid and wash material, final to influence cleaning
Effect.The content of the silica flour is preferably 35~52wt%, more preferably 40~50wt%.
In order to make solid wash the washing effect of material more preferably, it further includes auxiliary agent that the solid, which is washed in material, and the auxiliary agent is preferably
Surfactant, the surfactant is surfactant well known to those skilled in the art, not special to this application
Limitation.Preferably, the content of the surfactant is preferably 0~10wt%.
According to the present invention, in order to reach optimal washing effect, it includes: barium sulfate solid powder that the solid, which washes material,
60wt%, silica flour 30wt%, surfactant 10wt%.
The barium sulfate solid powder that herein described solid is washed in material is consistent with commercially available analysis pure chemicals, the silica flour
Granularity is preferably 30 microns~90 microns.
Present invention also provides wash the cleaning method that material carries out dry laser Particle Size Analyzer using above-mentioned solid, comprising:
The silica flour of the barium sulfate of 40~70wt% and 30~60wt% is placed in dry laser Particle Size Analyzer, is started
The injection procedure of the dry laser Particle Size Analyzer is cleaned for the first time, starts the cleaning of the dry laser Particle Size Analyzer
Function is cleaned again.
During above-mentioned cleaning, the sample introduction pressure of the injection procedure is preferably 2.0~4.0bar, and sample introduction speed is excellent
It is selected as 30%~50%；Preferably, the sample introduction pressure be 2.5~3.8bar, the sample introduction speed be 36%~
45%.The sample introduction pressure is less than normal, then solid washes material and is not easy to scatter, and influences cleaning effect；The sample introduction excessive velocities, then inhale
The impurity being attached on pipeline is difficult to efficiently remove, and needs wash number more, and the sample introduction speed is excessively slow, then solid is washed material and do not had
Have completely into pipeline, also will affect cleaning effect.
The application washes the placement location expected in the dry laser Particle Size Analyzer to the solid and does not limit particularly
System, in order to keep the cleaning effect of the dry laser Particle Size Analyzer preferable, preferably washes material for the solid and is placed in the dry method
The sample cell entrance of laser particle size analyzer makes dry laser Particle Size Analyzer from entrance to outlet under the action of air-flow, can
To realize comprehensive cleaning.
During above-mentioned cleaning, the number cleaned for the first time is preferably 3~5 times, the number cleaned again
Preferably 3~5 times, the application is not particularly limited the number of the cleaning, can be depending on specific cleaning effect.This Shen
The mass ratio for please washing material and sample to be cleaned in the dry laser Particle Size Analyzer to the solid is not particularly limited, root
According to actual conditions, the solid that different quality may be selected washes material, or increases the number of cleaning.
The application using the solid particle of barium sulfate and silica flour as washing material, by dry laser Particle Size Analyzer into
Solid is washed material and is blown into sampling system by sample program and cleaning function, and since solid is washed, material is not easy to adsorb in itself, density is larger, stream
Dynamic property is preferable, and light material can be taken away to the tube wall of analyzer, achievees the purpose that cleaning, and easy to operate simple.
