    摘要： Stripping action of an alkaline paint stripper is improved when ammonia is partially or completely replaced with ammonium bicarbonate or chemical equivalent thereof which decomposes into ammonia and carbon dioxide. A benzyl alcohol solvent system containing at least ammonium bicarbonate is preferably a water-in-oil emulsion emulsified with oleic hydroxyethyl imidazoline and thickened with hydroxypropyl cellulose or hydroxypropyl methylcellulose. A mixture of ammonium carbamate and ammonium bicarbonate identified as ammonium carbonate is the preferred activator for this alkaline paint stripper. Improved stripping can also be provided by reacting ammonium bicarbonate and ammonia in situ within the water-in-oil emulsion.

    摘要： A liquid for removing printing and screen printing inks consists of an essentially anhydrous mixture of (a) .gamma.-butyrolactone and/or N-methyl-2-pyrrolidone in an amount of up to 25% (v/v) and/or (b) propylene carbonate in an amount of up to 90% (v/v), and (c) up to 90% (v/v) of a high-boiling aromatic compound or a mixture of such compounds having a relative evaporation rate with respect to N-butyl acetate of 0.01 or less. Such a liquid can remove all printing and screen printing inks, and it is considerably less unhealthy than the known cleaning liquids.

    摘要翻译： 当氨被部分或完全替换为分解成氨和二氧化碳的碳酸氢铵或其化学当量时，碱性涂料汽提器的剥离作用得到改善。 至少含有碳酸氢铵的苄醇溶剂体系优选是用油酸羟乙基咪唑啉乳化的油包水乳液，并用羟丙基纤维素或羟丙基甲基纤维素增稠。 确定为碳酸铵的氨基甲酸铵和碳酸氢铵的混合物是该碱性涂料剥离剂的优选活化剂。 还可以通过在油包水乳液中原位使碳酸氢铵和氨反应来提供改进的汽提。

    摘要： Composition and method of removing a coating painted on a surface. The method involves applying to the surface an acetone based composition containing an organosilicon compound, rubbing the acetone based composition into the surface, and removing from the surface the painted coating and the acetone based composition. The composition is a mixture of 1 to 75 percent by weight of acetone; 1 to 10 percent by weight of water; and 1 to 20 percent by weight of a volatile silicone fluid. The volatile silicone fluid having a vapor pressure of less than 0.10 mm Hg.

    摘要： Use of (C.sub.1 -C.sub.5) alkyl esters of aliphatic (C.sub.8 -C.sub.22) monocarboxylic acids for removing fat, inks and the like from printing apparatus, in particular from offset printing machines, and a cleaning agent for this, containing as its main component a (C.sub.1 -C.sub.5) alkyl ester of an aliphatic (C.sub.8 -C.sub.22) monocarboxylic acid or a mixture of such esters.The most suitable esters are methyl, ethyl or isopropyl esters or mixtures thereof, and particularly expedient is an ester mixture obtained by interesterification of an oleic acid containing oil or by esterification of an acid mixture having a corresponding composition.The ester or ester mixture may be admixed with up to 50% by weight of vegetable oil.Further, the ester or ester mixture or the mixture thereof with vegetable oil may be emulgated in water in such amount that the water phase comprises up to 50%, preferably 25-35% by weight of the emulsion using an emulsifier in an amount of 1-10%, preferably 3-5% by weight of the emulsion. In that case it is convenient to further add a corrosion inhibitor in an amount of up to 2%, preferably 0.5-1% by weight of the emulsion.These esters and mixtures are low viscosity substances which are excellent and quickly acting solvents for inks, etc. They are moreover biologically degradable, non-toxic and have a low vapor pressure so that they do not involve any risk for the environment.
