Water-soluble coloured lead or coloured chalk and method for preparing the same |
| abstract |
A colored lead or a colored chalk is proposed which contains 1 to 30% by weight.nPolyvinyl alcohol as a binder and 1 to 25% by weight of a monomeric polyalcoholnand / or an oxyethylated polyphosphate as a plasticizerncontains. Such, still fillers, colorants, lubricants and optionallynStarting mixtures containing auxiliaries are first mixed intensively homogeneouslynand then extruded into mine or chalk strands. The strandsnonly have to be cut to length. A drying step like minenor chalks based on a water-swellable cellulose derivative. |
