| 摘要 |
<p>The invention relates to the use of hydrocarbons or hydrocarbon mixtures as additives for reducing the dust caused by dry, especially powdery chemical products for construction, especially hydraulically binding or cement-based materials, such as tile adhesives, jointing mortar, filler, sealing materials and the like. Such dedusting additives based on hydrocarbons or hydrocarbon mixtures create a long-lasting dedusting effect on the chemical products treated therewith, an effect which is maintained both in closed storage and in open storage, especially under atmospheric oxygen, without affecting the treatment and application characteristics of the chemical products for construction treated in this way.</p> |
