    • "FORMULATION FOR PRODUCING A WRITING ARTICLE, PROCESS FOR MANUFACTURING A WRITING ARTICLE AND A WRITING ARTICLE", wherein the formulation of said writing article can optionally comprise the following components (with a variation of ±2.5%): ABS (Acrylonitrile-Butadiene-Styrene, 37-50%), SAN (Styrene- Acrylonitrile, 14%), Graphite (35-42%), Calcium Stearate (5-10%), Stearin (8%), Talc (5-23%), Mineral Oil (2-3%), Polyethylene (1%), Bentonite (5-15%), Calcium Carbonate (1%). Said article (1) is defined as a single-piece object (2), which has an integral tip (3) that is produced by sharpening; the body of said single-piece object (2) is configured according to a profile standard, and may include multiple sides (4) giving said single-piece object an hexagonal appearance, or even only one encircling side (5), which gives said single-piece object a cylindrical appearance. The manufacturing process consists of the following steps: (a) weighing the raw materials; (b) homogenizing the raw materials using mixing equipment, into which all of the raw materials are fed; (c) feeding the mixture obtained after processing the raw materials in the mixer into a piece of equipment called a pelletizing extruder; (d) feeding the granulated material obtained after processing the mixture in the pelletizing extruder into a second extruder; (e) producing a continuous graphite bar; (f) cutting the graphite bar into bar sections of adequate length according to the size of a pencil; (g) sharpening the graphite sections; and (h) printing, a step that defines obtaining the final product: a writing article (1), which can then be packaged.
    • “制剂用于生产书写制品,用于制造的书写ARTICLE和写的文章” worin所述写入制品的制剂可以任选包括下列组分(具有±2.5%的变化):ABS(丙烯腈 - 丁二烯 - 苯乙烯 ,37-50%),SAN(苯乙烯 - 丙烯腈,14%),石墨(35-42%),硬脂酸钙(5-10%),硬脂酸(8%),滑石(5-23%),矿物油 (2-3%),聚乙烯(1%),膨润土(5-15%),碳酸钙(1%)。 所述制品(1)被定义为一个单件对象(2),其具有一体地尖端(3)即通过锐化产生; 所述单件对象(2)的主体被配置雅丁到配置文件的标准,并且可以包括六边形的外形的多个侧面(4),得到所述单件对象,甚至只有一个环绕侧(5),其给出说 单件对象的筒状的外观。 制造过程besteht以下步骤组成:(a)称量原料; (B)使用均化混合设备的原料,在其中所有的原料被输送; (C)供给加工原料进入混合器成一台设备称为造粒挤出机后获得的混合物; (D)将在造粒挤出机将该混合物加工成第二挤出机之后获得的粒化材料; (E)产生连续的石墨棒; (F)切割所述石墨棒成适当长度gemäß到铅笔的大小的条段; (G)锐化石墨部; 及(h)打印中,步骤做了定义获得最终产物:书写物品(1),然后可将其包装。
