Description
Uppfinnare: A. Sundelin.
I patentet 1463 heskrives ett forfarande vid tillverkning av formade fiberprodukter, t. ex. fiberplattor, varvid en fuktig, ligninhaltig, eventuellt limmad trafibermassa, framstalld ur en vattenuppslamning, torkas, eventuellt under samtidig pressning, vilket forfarande kannetecknas av, att fiberuppslamningen eller den mer eller mindre avvattnade fibermassan forsatles med halogener eller halogenaNspaltande amnen °eh att vid darvid skeende reaktion bildade vattenolosliga halogenforeningar, sasom halogenlignin, Ia kvarbliva i fibermassan under den efterfoljande torkningen resp. pressnin gen.
Bet liar nu visat sig, att man med fordel kan anvanda klorerat vattenglas, t. ex. natronvattenglas, sasom halogena-vspaltande amne. Bet klorerade vattenglaset bor darvid icke innehalla storre mangd klor an som svarar mot det mer eller mindre utspadda vattenglasets utsaliningsgrans.
Exempel. Fibermaterialet behandlas enligt det i patentet 120 463 angivna exemplet, men vid malningen i kontinuerlig hollandare tillsattes f5rst 0,5 (;-'0 hartslim, raknat pa fibermaterialets torrvikt, och i slutet cv hollandaren tillsattes 100 % av en losning, erhallen genom att inleda gasformig Iclor i en losning av vattenglas (1 del natronvattenglas (spec. vikt 1,35) + 15 delar vatten), tills den tillsatta klornaangden uppgar till 0,s % av 18sningens vikt. Darefter vidarebehandlas materialet enligt exemplet i patentet 1463, men med ute- slutande av kloreringssteget.
