Description

Säurefester und isolierender Baustoff Bei der Verarbeitung von Holz und .sonstigen vegetabilischen- Stoffen auf Zucker durch Hydrolyse mittels Säure wird neben. dem Hydrolyseprodukt der Gellulose ein Rückstand erhalten, welcher überwiegend aus Lgnin besteht. Diesen Rückstand hat man bereits entsäuert und mit und ohne Zusatz von Bindemitteln brikettiert.Acid-resistant and insulating building material When processing wood and other vegetable substances on sugar by hydrolysis by means of acid will next. the hydrolysis product of the gelulose obtained a residue, which predominantly consists of lgnin. This residue has already been deacidified and with and without additives briquetted by binders.

Es wurde nun gefunden, daß man derartige Preßkörper, welche man aus dem entsäuerten Rückstand ohne Zusatz von Bindemitteln, gegebenenfalls mit Zusatz von Füllstoffen, erhält; als säurefesten und isolierenden Baustoff verwenden kann. Diese P'reßkörper sind wegen ihrer dichten: glatten Oberfläche besonders für die Herstellung von säurefesten Gefäßen `und Belägen und auch als Wand-und Fußbodenplatten sowie als Baustoff verwendbar; für den gute thermische und elektrische Isolierfähigkeit verlangt wird.It has now been found that such compacts, which one from the deacidified residue without the addition of binders, optionally with additives of fillers, obtained; can be used as an acid-proof and insulating building material. These pressed bodies are because of their dense: smooth surface especially for Manufacture of acid-proof vessels `and coverings as well as wall and floor panels as well as usable as building material; for good thermal and electrical insulation is required.

Gewünschtenfalls können dem Abfallmaterial' auch noch Füllstoffe oder Hilfsstoffe> welche dem Anwendungszweck dienen, zugesetzt werden. Als solche kommen: z. B. Kieselgur und Asbest in Betracht; man kann dem Abfall-Lignin z. B_ 2o bis. 5oo,'o Asbest' zusetzen.If desired, the waste material 'can also fillers or Auxiliaries> which serve the purpose of use, are added. As such come: z. B. kieselguhr and asbestos into consideration; you can the waste lignin z. B_ 2o to. Add 5oo, 'o asbestos'.

Für die Verwendung des Hydrolyserückstandsmaterials in Form von Preßkörpern als säurefester isolierender Baustoff ist es von entscheidender Bedeutung, daß die natürlichen Eigenschaften des Materials nicht durch Zusatz von Bindemittelxt für den Verwendungszweck ungünstig beeinflußt werden, und daß das Abfallmaterial in einer Form erhalten wird, daß es zum überwiegenden Teil aus Lignin besteht, weil nur diesem die Eigenschaft der großen: Säurefestigkeit zukommt, nicht aber den Verwandlungsprodukteza. der Cellulo&e, welche etwa dem Lignin beigemischt sind.For the use of the hydrolysis residue material in the form of compacts As an acid-proof insulating building material, it is of vital importance that the natural properties of the material not by adding binder text for the intended use are adversely affected, and that the waste material in a form is obtained that it consists predominantly of lignin because only this has the property of great strength: acid resistance, but not the products of metamorphosis. the Cellulo & e, which are mixed with the lignin.
