PROCESS FOR IMPROVING OF EXPANSION CHARACTERISTIC OF THERMICALLY EXPANDARLE SULPHUR-GRAPHITE GRAINS.

摘要

in the invention, a thermally expandable sulfuric acid - grafitru00e9szecsku00e9k expanziu00f3stulajdonsu00e1gainak suitable procedure to regulate, which is characterised by the fact that the grafitru00e9szecsku00e9k oxidant produced in the presence of sulfuric acid and sulfuric acid vu00e9gzettreagu00e1ltatu00e1su00e1val - a grafitru00e9szecsku00e9ket the exp anziu00f3stulajdonsu00e1gokat affecting vizesmosu00f3folyadu00e9kkal compound containing 2 and 8.a positive ph between 3 and 7 elu00e9ru00e9su00e9igmossu00e1k, where the ph is measured in the washed grafitru00e9szecsku00e9ktu0151l elvu00e1lasztottmosu00f3folyadu00e9kban sulphuric acid, and drying the particles, and thus a thermal expandable sulfuric acid - grafitru00e9szecsku00e9kintumesszenciu00e1s tu0171zvu00e9de the application relates to ku00e9szu00edtmu00e9nyekelu0151u00e1llu00edtu00e1su00e1ra lu00e1ngvu00e9du0151 lmi as an additive, in particular amelyku00e9szu00edtmu00e9nyeket walls in buildings.floor and / or mennyezetu00e9benlevu0151 breakthroughs, transfers and similar openings in fire protective tu00f6mu00edtu00e9seihezhasznu00e1lnak. oh
