Polymer-thickened deicing composition and anti-icing composition for aircraft |
摘要 |
The composition described includes as thickener water-soluble crosslinked acrylic homopolymers having a mean molecular weight of from 750,000 to 1,250,900 and a viscosity, in the form of a 0.5% strength by weight aqueous solution with a pH of 7.0 and a temperature of 20 DEG C., of from 1000 to 13,000 mPaxs, measured with a Brookfield viscometer at 20 rpm, and in addition thereto from 0.02 to 1.5% by weight of at least one nonionic surfactant formed from an alcohol having 6 to 22 carbon atoms which is reacted with from 1 to 10 molecules of a low molecular mass alkylene oxide, and from 0.03 to 1% by weight of at least one water-soluble salt compound of an inorganic acid or a carboxylic acid or a mixture thereof. The deicing liquid described is notable for a long holdover time and good flowoff behavior.
