Förfarande och anordning för fibrillering av cellulosahaltiga materialer |
摘要 |
<p>In a method for manufacturing fibril cellulose, cellulose based fibre raw material is processed mechanically in a refining gap for separating fibrils. The fibres to be refined are subjected to the action of a surface roughness Ra provided by grits elevated from a refining surface delimiting the refining gap, said surface roughness being lower than 3μm, advantageously lower than 2μm. The refining surface is formed by spraying grits and binder onto a substrate.</p> |
