Author:

Graphite powder is insoluble in water,dry and wet sampling dispersion are all okay, Generally, due to the low cost of wet laser particle size analyzer, wet sampling system is recommended.

When test graphite powder, need cleanser essence or Polyoxyethylene Sorbitan Fatty Acid Esters as dispersant, ultrasonic time need 1 minute, the main purpose is to make the sample fully dispersed, with water as the dispersion medium, Stable and precise particle size distribution could be got then.

Graphite powder are mainly used as battery materials, the average particle size is 16-18 micron, winner2000E and 2000ZDE laser particle size analyzer can meet the test requirements.

How to use laser particle size analyzer to control glass materials particle size distribution?

The glass industry control of the raw material is divided into three aspects: one is the composition of the control; two is batch control; three is the control of particle size, including maximum particle control ,control of ultrafine powder, and control for a variety of different particle ratio. With the continuous development of science and technology progress, the industry has become more and more profound understanding of the impact of raw materials on the quality of glass,and particle size control has been widely accepted by the customers.

How to choose laser particle size analyzer for coal water slurry

Coal water slurry, as a kind of clean oil, has the advantages of high concentration, fine particle size, high fluidity, high combustion efficiency, environmental protection, energy saving, and so on. It has been widely used in industrial boiler and power plant boilers and industrial furnaces. In addition to the large power plants, combustion equipment steel, refining and other enterprises, more and more small and medium sized boiler (20 tons) also started burning water coal slurry. Considering the energy structure of our country and the situation of our country, The government is to encourage coal water slurry industry development, Therefore, the production and marketing prospect of coal water slurry is very broad.

Laser Particle Size Analyzer Application In Petrochemical Industry

Laser Particle Size Analyzer Application In Petrochemical Industry Petrochemical industry have strong requirement for particle size measurement,Particle size is a very important parameter in petrochemical industry. In 90s, the traditional method of sieve analysis and centrifugal settling has been replaced by laser scattering particle size measure method,Laser scattering particle size analysis has become a fast, accurate and efficient method for the analysis of particle size. Petrochemical industry, there are mainly the following categories of samples need to detect particle size: (1) catalyst: including research and quality control. This is the main application of the refinery and the catalyst plant. (2): analysis of flue gas flue gas particle content and distribution pipeline in front hood, to protect the safety hood. (3) clay: lubricating oil additive. (4) the emulsion: the particle size determines the stability of the emulsion. (5) PVC, styrene and ABS: quality control and research of raw materials and products. (6) chemical fiber: quality control and research of raw materials and products. Our famous customer: America DuPont Co., Ltd. ,In 2006, Choose Winner2000ZDE Laser Particle Size Analyzer and Winner801 DLS nanometer particle size analyzer for their Lab research institute of Guangzhou branch company.
