Abstract
Plate av lignocellulosemateriale og en | ; f fremgangsmåte for fremstilling av en sli. k plate. Materialet desintegreres til partikler eller fibrer, tørkes, limes før eller etter tørkingen, formes til en matte og tørkes til slutt ved varmpressing til en ferdig plate. I I samsvar med oppfinnelsen modifiseres ligninet. , kjemisk minst i overflateskiktet av partiklene ; eller fibrene før slutt-tørkingen, slik at det !oppnås en øket bindingsreaktivitet ved innfø-ring av hydrofile grupper og slik at myknings- : temperaturen for ligninet senkes. Derved sul- i foneres lignocellulosematerialet i platen del-vis, slik at det organisk bundne svovel over- : skrider innholdet av nativt svovel i materialet, men er lavere enn 0,4%.Plate of lignocellulosic material and a | ; f method of making a sli. k plate. The material is disintegrated into particles or fibers, dried, glued before or after drying, formed into a mat and finally dried by hot pressing into a finished plate. In accordance with the invention, the lignin is modified. , chemically at least in the surface layer of the particles; or the fibers before the final drying, so that an increased binding reactivity is obtained by the introduction of hydrophilic groups and so that the softening temperature of the lignin is lowered. Thereby, the lignocellulosic material in the plate is partially sulfonated, so that the organically bound sulfur exceeds the content of native sulfur in the material, but is lower than 0.4%.
