Test Method
Sample
Aqueous solutions of SEDORAN FF at the concentrations listed in the table above were used as neutral samples. The pH of the neutral sample was adjusted to 12.8 using a 1 mass% aqueous solution of sodium metasilicate 9-hydrate to make it an alkaline sample.
Methods of Measuring Cleaning Ratio
The following standard contaminated plates (steel plates) were immersed in the sample adjusted to 20°C, 40°C, 55°C, or 80°C for 10 or 20 seconds and then removed and allowed to dry naturally. The cleaned steel plate was taped with cellophane tape and the remaining contaminants were transferred to a blank sheet of paper to obtain the reflectance measurement sample (1).
The standard contaminated plate was also taped with cellophane tape, and the contaminants were transferred to a blank piece of paper to obtain the reflectance measurement sample (2).
Next, the reflectance at a wavelength of 440 nm of the contaminated surfaces (1) and (2) and the surface with cellophane tape attached to the white paper (3) were measured with a multiple light source spectrophotometer, MSC-2 [Suga Testing Machinery Co.
<How to Prepare Standard Contaminated Plates>
Cold-rolled steel sheets that had been polished and cleaned were soaked in the following standard contaminants for 10 seconds, then removed and dried.
Composition of standard stain
Carbon black ： 0.3% by mass
#60 spindle oil ： 2.5% by mass
Oleic acid ： 0.5% by mass
Carbon tetrachloride ： 96.7% by mass
Total ： 100.0% by mass
<Calculation formula for cleaning rate>
Cleaning rate % = 100 x (RW - RS)/(RO - RS)
RW: Reflectance of (1)
RS: Reflectance of (2)
RO: Reflectance of (3)
