Transmittance Spectrophotometer for Resin Pt-Co Measurement

Chemical Industry | 2017-08-14 17:18:33
  • Pt –Co standard solution is made by potassium chloroplatinate and cobalt chloride. Comparing the standard liquid with the sample, we can get the sample’s Pt-Co color value. Only liquid can have Pt-Co color value, how can we test powder?

    Brominated epoxy resin (BE or BEO) is a kind of powder, because of its good electrical performance and physical and mechanical properties have been widely used in the electronics, automotive, office equipment, household appliances and other industries.

  • It is insoluble in water, alcohol, xylene, butanone, but soluble in DMF, ethylene glycol dimethyl and so on. Many companies have requirements on Pt-Co color value of brominated epoxy resins, and in order to control its color quality, it is important to measure it by spectrophotometer.

    Transmittance spectrophotometer CS-810 is specially designed for the measurement of liquid transmittance, color and other parameters. Today we will introduce how to measure the Pt-Co color of brominated epoxy resin with it. The following are the tools that we need.
  • transmittance spectrophotometer

    Brominated epoxy resin is in powder form. We will use dioxane to dissolve it into liquid. It is difficult to dissolve in normal temperature, it need to be placed in the warm water, after it is fully dissolved, we can measure.

  • In addition to measuring the Pt-Co color, the instrument also can measure Gardner color for products such as solvents, acids, perfumes and varnishes; Saybolt color for gasoline, white oil, kerosene, lubricating oil and paraffin oil.
