摘要： Oversprayed paint in a paint spray operation is detackified by dosing the water of the waste water system of such operation with a composition comprising a polymer and aluminum sulfate. The polymer contains at least about 10 mole percent of cationic mer units of monoethylenically unsaturated monomer.

摘要： Oversprayed paint in a paint spray operation is detackified by dosing the water of the waste water system of such operation with a composition comprising an amphoteric polymer and aluminum salts. The amphoteric polymer contains at least about 10 mole percent of cationic mer units of monoethylenically unsaturated monomer and at least 1 mole percent of anionic mer units. The aluminum salt preferred is aluminum sulfate, or its hydrates, for example alum. The amphoteric polymers preferably contain DMAEM, DMAEM.multidot.H.sub.2 SO.sub.4, DMAEM.multidot.MCQ, or mixtures thereof, with acrylic acid, methacrylic acid, AMPS, or mixtures thereof. The amphoteric polymers may also contain neutral monomers such as (meth)acrylamide.

摘要： A method and an apparatus for dispersing or dissolving a pelletized material in a liquid, in which a pelletized material is placed on a platform in a container having a lower chamber portion, and a stream of liquid is introduced into that lower chamber to produce a vortex of the liquid which washes across the pelletized material, thereby causing it to become dispersed or dissolved into the liquid.
