The oil can always be removed during the stiffing. Third, your muneca may be contaminated with particles either from worn and loose fibers on the muneca or from particles in the air that have landed on the guitar.

油可以在强化时去除。3，你的涂施包可能被破碎的布纤维污染了也或者是空气中的飘尘落到了乐器表面。

Fe2O3 acts as an activator more than a catalyst in the desulfurization reaction with lime. Fe2O3 acts as the "activation center" around which CaO particles are sulfurized. The new dispersal formation mode of product differs from the compact layer that used to be. And the pore structure of product layer on the surface of lime particles is optimized, which makes SO2 penetrate into core parts of lime more easily. As a result, the desulfurization reaction is developed deeper into the core parts of absorbent.

氧化铁所起的是改变石灰颗粒表层产物生成方式的活化作用，使反应生成物不会形成一个致密的外壳，而以氧化铁为活性中心进行硫化反应，形成了分散的硫酸钙产物堆积，改善了硫化过程中的表面孔隙结构，减少了石灰颗粒表面硫化产物层对反应气体向石灰颗粒内部扩散的阻力。
