After 25 minutes of dry vulcanization molding, and then impregnating 2% of the polyurethane release agent, it was dried at 120 degrees for 6 minutes, cooled, and then removed from the mold to obtain a finished glove.
测试物理性能：手套的扯断力达到 13N,伸长率达到 750%，不仅超过了 GB 10213-2006 一次性使用医用橡胶检查手套 的要求， 还达到了 GB 7543-2006 一次性使用灭菌橡胶外科 手套 的要求， 有广泛的应用前景。 Test physical properties: the tearing force of the glove reached 13N, the elongation reached 750%, not only exceeded the requirements of GB 10213-2006 disposable medical rubber inspection gloves, but also reached the GB 7543-2006 disposable sterilization rubber surgery The requirements of gloves have broad application prospects.
此外， 由于手套的内外两层都是丁腈橡胶材质， 中间的天然橡胶材质不与人体或外界 物质接触， 因此手套不会引起部分人群的过敏， 也对化学品、 溶剂有着很好的耐受性能。
In addition, since both inner and outer layers of the glove are made of nitrile rubber, the natural rubber material in the middle is not in contact with the human body or foreign materials, so the glove does not cause allergies in some people, and is also well tolerated by chemicals and solvents. performance.
