    • A composition is provided comprising two liquids which are separately maintained prior to forming an admixture during delivery to a surface to be treated, whereupon the admixture generates a foam sufficient for cleaning efficacy and stability. A first liquid preferably includes a hypohalite, or a hypohalite generating agent and a second liquid preferably includes a peroxygen agent. The first liquid is thickened to a specified rheology, resulting in the generation of a highly effective foam. As the two liquids are initially separated, the hypohalite generating agent can be maintained in an environment free of peroxygen agent and otherwise conducive to their cleaning activity and stability up to the time of use. When the two liquids are allowed to mix, for example, by simultaneously pouring into a drain, the hypohalite and peroxygen react to liberate oxygen gas. As foam generation occurs, the escaping gas contacts surfactant in the solution, and creates foam which expands to completely fill the drain pipe. The expanded foam contains an excess of the hypohalite, which acts to clean the drain.
    • 提供了一种组合物,其包含两种液体,其在输送到待处理表面之前形成混合物之前分开保持,因此该混合物产生足以清洁功效和稳定性的泡沫。 第一液体优选包括次卤酸盐或次卤酸盐生成剂,第二液体优选包括过氧化剂。 第一液体增稠至特定的流变性,导致产生高效泡沫。 当两种液体最初分离时,次卤酸盐生成剂可以保持在不含过氧化物的环境中,否则有利于其使用时的清洁活性和稳定性。 当允许两种液体混合时,例如通过同时倒入排水管中,次卤酸盐和过氧化物反应释放氧气。 当发生泡沫发生时,逸出的气体与溶液中的表面活性剂接触,并产生膨胀以完全填充排水管的泡沫。 膨胀的泡沫包含过量的次卤酸盐,其用于清洁排水管。

    • A composition is provided comprising three liquids which are separately maintained prior to forming an admixture during delivery to a surface to be treated, whereupon the admixture generates a heated foam sufficient for cleaning efficacy and stability. A first liquid preferably includes a hypohalite, or a hypohalite generating agent, a second liquid preferably includes a peroxygen agent and a third liquid includes a reducing agent, such as a thiosulfate. The first liquid is thickened to a specified rheology, resulting in the generation of a highly effective foam. As the liquids are initially separated, they can be maintained in an environment free of reactants and otherwise conducive to their activity and stability up to the time of use. When the liquids are allowed to mix, for example, by simultaneously pouring into a drain, the hypohalite and peroxygen react to liberate oxygen gas, while the hypohalite and thiosulfate react to generate heat. As foam generation occurs, the escaping gas contacts surfactant in the solution, and creates foam which expands to completely fill the drain pipe. The expanded foam is hot as a consequence of the exothermic reaction, and further contains an excess of the hypohalite, both of which act to clean the drain.
    • 提供了一种组合物,其包含三种液体,其在输送到待处理表面之前形成混合物之前分别保持,因此该混合物产生足以清洁功效和稳定性的加热泡沫。 第一液体优选包括次卤酸盐或次卤酸盐生成剂,第二液体优选包含过氧化剂,第三液体包括还原剂,例如硫代硫酸盐。 第一液体增稠至特定的流变性,导致产生高效泡沫。 当液体最初分离时,它们可以保持在没有反应物的环境中,否则有利于它们在使用时的活性和稳定性。 当允许液体混合时,例如通过同时倒入排水管中,次卤酸盐和过氧化物反应释放氧气,而次卤酸盐和硫代硫酸盐反应而产生热量。 当发生泡沫发生时,逸出的气体与溶液中的表面活性剂接触,并产生膨胀以完全填充排水管的泡沫。 膨胀的泡沫由于放热反应而是热的,并且还含有过量的次卤酸盐,两者都用于清洁排水管。
