    Abstract: 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.

    Abstract translation: 当氨被部分或完全替代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。 含有至少碳酸氢铵的苄醇溶剂体系优选为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。 也可以通过在油包水乳液中将碳酸氢铵和氨原位反应来提供改进的汽提。
