查询词典 permeability

Knitting oil stable at high and low temperature was prepared by emulsification between 20# white oil as base oil and O-3 and O-6 of narrow molecular weight distribution, Span-80, Tween-80, PK, and barium petroleum sulfonate as emulsifier. Condensation point, residue analysis, emulsifying properties, permeability, antistatic performance and application effect were used to characterize knitting oil.
