Ⅰ.Product property and use
1. Dinonylnaphthalene calcium sulfate is a kind of
steady oil soluble antirust additives, which are
extensively applied in diversified antirust oils.
2. Since dinonylnaphthalene calcium sulfate also has
good emulsion resistance, it is most suitable for

Experiment methods |
①In a
glass test-tube of diameter 30mm-40mm and height
120mm-130mm, add test sample to 2/3 height and observe
from the tube side in greenhouse.
②Add 150# neutral oil (rubber industrial solvent oil for T705) to a
beaker, add in 5% sample and dissolve it fully. Put it
aside for 24 hours. If the solution has no white
precipitation and suspension,it's qualified. |
