Zum Weißen, Füllen und Glänzen (Satinieren) von Papieren und Kartons, sowie als Zusatz zu Farben wird neben Ton (Chinaclay), Asbest und Blanc fixe auch schwefelsaurer Kalk angewendet, und zwar teils als einfach gemahlener und geschlämmter Gips (Annalin) oder, wo es sich um bessere Qualitäten handelt, als gefällter schwefelsaurer Kalk. Letzteres durch Ausfällen der LösungFor whitening, filling and shining (satin finishing) of paper and cardboard, as well as In addition to colors, clay (Chinaclay), asbestos and blanc fixe also become more sulfuric Lime is used, partly as simply ground and slurried gypsum (Annalin) or where it is of better quality acts as precipitated sulphate of lime. The latter due to failure of the solution
ίο eines Kalksalzes mit Schwefelsäure oder gelösten schwefelsauren Salzen enthaltene Produkt wird technisch als Perlweiß (Pearlhardening) bezeichnet.ίο a lime salt with sulfuric acid or dissolved Product containing sulfuric acid salts is technically called pearl white (pearlhardening) designated.
Von Adolph Frank ist nun bereits früher .15 der Vorschlag gemacht (conf. S. 365 in Ho fm an η, Bericht über die Entwicklung der chemischen Industrie 1875, Braunschweig, Viewegs Verlag), zur Fällung von schwefelsaurem Baryt und schwefelsaurem Kalk die schwefelsaure Magnesia zu verwenden, welche sich als Kieserit massenhaft in den Kalisalzlagern findet, oder auch zu weiterer Vermehrung der Ausbeute an Füllstoff die Lösung der schwefelsauren Magnesia mit Ätzbaryt oder Ätzkalk auszufällen:Von Adolph Frank is now earlier .15 made the proposal (conf. P. 365 in Ho fm an η, report on the development of the chemical industry in 1875, Braunschweig, Viewegs Verlag), for the precipitation of sulfuric barite and sulfuric lime die To use sulfuric magnesia, which is found en masse as kieserite in the potash salt deposits finds, or to further increase the yield of filler, the solution of sulfuric acid magnesia with etching barite or to precipitate quick lime:
Mg Mg S O4 + Ca O = Ca S O4 + S O 4 + Ca O = Ca S O 4 + Mg Mg O.O.
Das nach letzterer Methode gewonnene Gemisch von Perlweiß und Magnesiumhydrat hat sich aber in der Praxis als nicht recht brauchbar erwiesen, weil es infolge der amorphen Beschaffenheit der Magnesia an der Faser schlecht haftet und außerdem durch seine alkalische Reaktion auf den Harzleim und auf zugefügte Farbstoffe ungünstig einwirkt. The mixture of pearl white and magnesium hydrate obtained by the latter method but has not proven to be very useful in practice because it is due to the The amorphous nature of the magnesia adheres poorly to the fiber and as well through its alkaline reaction has an unfavorable effect on the resin glue and on added dyes.
Um aus schwefelsaurer Magnesia und Ätzkalk oder Ätzbaryt einen für die Zwecke der Papierfabrikätion, sowie für Appretur von Textilstoffen brauchbaren Füllstoff zu erhalten, wendet man das folgende Verfahren an.In order to make from sulfuric magnesia and quick lime or Ätzbaryt one for the purpose of To obtain paper mill and filler that can be used for the finishing of textile materials, use the following procedure.
Eine Lösung von schwefelsaurer Magnesia oder von Kieserit wird mit der entsprechenden Menge zu Milch gelöschten Ätzkalks oder gelöstem Ätzbaryt ausgefällt und dann in das entstandene Fällungsgemisch unter Umrühren Kohlensäure im Überschuß eingeleitet; hierbei entsteht zunächst kohlensaure und dann gelöste, saure kohlensaure Magnesia. Nachdem alles oder doch der größte Teil des Magnesiumhydrats in Magnesiumbicarbonat umgewandelt ist, wird die Masse, event, unter öfterem Umrühren, längere Zeit der Luft ausgesetzt, wobei unter Entweichen von Kohlensäure neutrale kohlensaure Magnesia (Mg C O3 + 3 aq) event, neben geringeren Mengen eines etwas basischeren Magnesiumcarbonates in zarten Nadeln ausgeschieden wird, welche ebenso wie die Kristalle des schwefelsauren Kalks, denen sie in Form und Volumgewicht ziemlich gleichen, sich mit der Papier- oder Stoffaser gut vereinigen und binden. Durch Behandeln im Vakuum oder durch Erhitzen des mit Kohlensäure gesättigten Gemisches auf 70 bis 800C. kann die Abscheidung des neutralen kohlensauren Salzes beschleunigt und zugleich die entweichende Kohlensäure für neue Verwendung wieder erhalten werden. Erhitzt man endlich die Lösung des sauren kohlensauren Magnesiums unter hohem Druck auf 160 bis 1700 C, so fällt die neutrale kohlensaureA solution of magnesia sulfuric acid or kieserite is precipitated with the appropriate amount of quicklime or dissolved acidic baryta which has been slaked into milk, and excess carbonic acid is then introduced into the resulting precipitation mixture with stirring; this results in carbonic acid and then dissolved, acidic carbonic acid magnesia. After all or at least most of the magnesium hydrate has been converted into magnesium bicarbonate, the mass is exposed to the air for a longer period of time, possibly with frequent stirring, with the escape of carbonic acid, neutral carbonic acid magnesia (Mg CO 3 + 3 aq) and less Quantities of a somewhat more basic magnesium carbonate are excreted in delicate needles which, like the crystals of calcium sulphate, to which they are quite similar in shape and volume weight, combine and bind well with the paper or fabric fiber. By treating in vacuo or by heating the mixture saturated with carbonic acid to 70 to 80 ° C., the deposition of the neutral carbonic acid salt can be accelerated and at the same time the escaping carbonic acid can be recovered for new use. If the solution of the acidic carbonic acid magnesium is finally heated under high pressure to 160 to 170 ° C., the neutral carbonic acid falls
