    • This invention relates to new liquid or fluid polyamine/carbonic acid salt compositions free from crystalline content and their preparation from mixtures containing at least one aliphatic or cycloaliphatic polyamine, an aliphatic or cycloaliphatic hydroxyamine having at least one hydroxyl group and at least one amino group, and water and optionally diluents and/or conventional auxiliary agents and additives, by the addition of carbon dioxide. The proportion of polyamine to hydroxyamine is in the range of from about 95:5 to 10:90 % by weight, the quantity of water added is from about 0.01 to 5 mol of H.sub.2 O per amine equivalent (but at least 1 mol of water per mol of CO.sub.2) and the quantity of CO.sub.2 added is from about 0.01 to 0.99 mol of CO.sub.2 per amine equivalent. The invention further relates to the use of these liquid polyamine/carbonic acid salt compositions for the production of foamed polyurethane ureas, especially for coating substrates or for the production of sheet products, using prepolymers preferably containing blocked isocyanate groups and the liquid polyamine/carbonic acid salt compositions as chain lengthening agents and/or crosslinking agents and at the same time as physiologically harmless blowing agents.
    • 本发明涉及不含结晶含量的新的液体或流体多胺/碳酸盐组合物,它们由含有至少一种脂族或脂环族多胺,至少具有一个羟基和至少一个氨基的脂族或脂环族羟胺的混合物制备, 和水以及任选的稀释剂和/或常规助剂和添加剂,通过加入二氧化碳。 多胺与羟基胺的比例在约95:5至10:90重量%的范围内,加入的水的量为约0.01至5摩尔每胺相当的H 2 O(但每个至少1摩尔水 二氧化碳的摩尔数),加入的二氧化碳的量为每个胺当量约0.01至0.99mol的CO 2。 本发明还涉及这些液态多胺/碳酸盐组合物用于生产泡沫聚氨酯脲,特别是用于涂覆基材或用于生产片状产品的优选使用含有封端异氰酸酯基团的预聚物和液态多胺/碳酸 盐组合物作为增链剂和/或交联剂,并且同时具有生理上无害的发泡剂。

    • The invention relates to a method for the automatic control of batch processes by means of a process control in which the automatic control programs access individual control modules, wherein a) the control instructions and parameter definitions contained in the partial formulations or phases of the formulation program are stored in a separate program level for the activation, interlocking and switch-on blocking of actuators in the field, b) in the separate program level, the control instructions and parameter definitions for each actuator to be activated are collected actuator by actuator and, if appropriate, logically combined, and c) the currently effective activations, interlockings and switch-on blockings are output, actuator by actuator, to the process operating and monitoring system.
