Being simplicity and efficient manufacturing method in order to prepare the core of the pencil from simplicity in order

摘要

Dampen the process, mix the powder and the binding agent the process and the blend which obtain the graphite powder to which this invention being simplicity in order to manufacture the core of the pencil from the second hand of aluminum industry or pot liner for abolition and something which relates to efficient manufacturing method, administers thermal shock processing the process which pulverizes the above-mentioned liner in small size, vis-a-vis process, wash the reaction product with the distilled water process and dry ones which add chromic acid to the liner which is pulverized, smooth does finely at necessary water content, pressure easing to put out process and the kneading powder which form the hard kneading powder, the product of disk formThe process which is obtained, the dry disk, under inactive/reducing atmosphere, 1 - 6 hours, the process which is heated, and the process which obtains the core of the pencil, is included with the furnace of the temperature range of the 400-1200C.
