| 摘要 |
The present invention describes a new fire-extinguishing and fire-prevention process in which calcium precipitates and/or specially activated calcium carbonate, i.e., specially finely ground or finely divided calcium carbonate that is environmentally friendly and not injurious to health, is used. This seals the burning surface immediately and breaks the reaction chain. The toxic gases and injurious substances that are released by the thermal decomposition of plastics react with the calcium carbonate and are bound so that no dioxins, including toxic chlorinated and/or fluorinated hydrocarbons, are formed.
