現在把我們用土法制造膠布初步經驗介紹如下,以供参考: 成分:生橡膠8斤松香(細末) 12斤氧化鋅(細粉) 12斤凡士林7斤工业用汽油30斤(以上成分約可做氧化鋅橡成硬膏0.8公尺寬65公尺长) 制造方法: 先取生橡膠(軋成薄片狀)剪成細小塊,加适量工業用汽油浸渍10小时,每隔2—3小时攪拌一次,直至变成糊狀,將松香細末分次加入,用力不断攪拌,同时將氧化鋅細末徐徐加入,直至無顆粒为止(粘度較大时可加适量汽油,目的使打膠輕松,如粘度稀薄,会影响干燥时間),最后加入已熔融的凡士林,使攪拌均匀,即可上膠。俟橡膠稍干,將硬紗布合上去即为成品。据已使用單位反映,粘度适合,部分有厚薄不匀現象(現在已改进)。注意事項: 1.操作工场可在露天广場,將細布拉平,無线 Now we introduce the preliminary experience of using plastics to manufacture adhesive tapes for reference: Composition: Raw rubber 8 pounds of rosin (fine powder) 12 pounds of zinc oxide (fine powder) 12 pounds of petroleum jelly 7 pounds of industrial gasoline 30 pounds Made of zinc oxide rubber into plaster 0.8 meters wide and 65 meters long) Manufacturing method: Take raw rubber (rolled into thin pieces) into small pieces, add appropriate amount of industrial gasoline to dip for 10 hours, stir once every 2-3 hours, Until it becomes a paste, the rosin powder is added in portions, and stirring is continued. At the same time, the zinc oxide powder is gradually added until no particles are present (the gasoline can be added when the viscosity is large, for the purpose of making the rubber easy, such as thinning viscosity. , will affect the drying time), the final addition of molten petrolatum, so that uniform mixing, you can sizing. The rubber is slightly dry, and the hard gauze will be finished. According to the units used, the viscosity is suitable, and there are some uneven thicknesses (now improved). Matters needing attention: 1. The operation workshop can be in the open square, will fine Brapin, wireless
