Traditional Chinese Antistatic resin pencil: Workshop Formula, Ratios & Method
In short: Traditional Chinese Antistatic resin pencil. This entry documents a formula & ratios taken from Chinese practical-technology literature, written for small-scale makers and home producers. The text below is the full English translation of the original Chinese workshop notes, covering materials and quantities, the step-by-step sequence, and the practical cautions recorded in the source. Roughly 2846 words of English technical text, translated and preserved without editing. It is intended for experimental and reference use, not for regulated or commercial certification.
Antistatic resin pencilIn the past, people used natural wood to make pencils. Due to the increasing shortage of this type of wood, in order to ensure a stable supply of pen-making raw materials, reduce costs, and improve quality, people are scrambling to study the use of resin instead of wood to make resin-shaped pencils. However, since the resin itself is easily charged with static electricity, debris often adheres to the pen barrel, blade or cutter during cutting, making it troublesome to wipe off, and may also stain your hands. It is difficult for the cutter to perform continuous cutting, which is very inconvenient. Therefore, some people add a certain amount of antistatic agent when manufacturing resin rod ingredients to overcome the above disadvantages. However, the effect is not ideal. The antistatic agent often leaks out and adheres to the pen barrel. The film has an unpleasant sticky feeling and therefore loses its antistatic ability. Therefore, how to make the static inhibitor evenly distributed in the resin and keep its properties stable has become the focus of attention.Hiroyuki Shiga solved this problem by creating a resin-shaped pencil with antistatic agent microcapsules or absorbers that are evenly dispersed. The antistatic agents he uses include guanidine derivatives, phosphoric acid-containing anion activators, polyoxyethylene alkylphenols, polyethylene glue, silicone oil, propylene, isobutylene and other high molecular compounds, and colloidal solutions such as silver sulfide, ferric oxide, and silicon tetrachloride. The absorbers of antistatic agents include alginic acid, polyvinyl alcohol, gelatin, gum arabic, dextrin, egg protein, epoxy resin, polystyrene, etc., as well as certain inorganic materials, such as activated clay, alumina, etc. The solution hardening method, organic solvent aggregation method, etc. are used to stabilize the antistatic agent, form microcapsules, and improve the antistatic ability. It is generally required that the antistatic agent will not evaporate under heat treatment conditions; adhere well to the resin; be evenly distributed; …
