The present invention relates to a pencil for writing or colouring, which includes the following three layers produced by co-extrusion: a non-expanded polyolefin lead; with a non-expanded protective intermediate layer surrounding the lead and including a mixture of polystyrene and EVA; and an expanded synthetic wood material made of a styrene polymer surrounding the protective intermediate layer, the thickness ratio of the protective intermediate layer to the radius of the lead being from 0.05 to 0.17, preferably from 0.07 to 0.15.
摘要:
Die Erfindung betrifft eine Graphit enthaltende Mine oder Kreide, bei der das Graphit in einer polymeren Bindemittelmatrix gebunden ist, wobei die Bindemittelmatrix zumindest teilweise aus wenigstens einem ersten Polymer besteht, welches ein mit Maleinsäureanhydrid gepfropftes Polyolefin ist. Die Erfindung betrifft außerdem einen Stift mit einer Graphit enthaltenden Mine.
摘要:
A chalk line device that includes a housing, a reel mounted for rotation within the housing, a liquid container disposed within the housing, and a handle connected with the reel and extending outside the housing is provided. The reel is constructed and arranged to carry a chalk line wound thereon. The reel is positioned in the liquid container such that the chalk line wound therein is at least partially submerged in the liquid chalk received in the liquid container. The liquid container has a sealed configuration and an unsealed configuration. In the unsealed configuration, the liquid container is configured to receive liquid chalk therein. In the sealed configuration, the liquid container substantially seals the liquid chalk received therein. The handle is operable to wind up the chalk line onto the reel.
