在焊条制造过程中,涂料中常加入許多鉄合金,进行脫氧和增补燒損的合金元素。同时为了使制成的焊条有一定的坚固性和强度,又必須渗入相当数量的水玻璃作为涂料的粘結剂。这兩种成分在互相进行攪拌时,就会产生发酵現象,发生有似沸騰,并帶有大蒜味的化学反应。 Si(Mh)+2NaOH+H_2O→Na_2SiO_3+2H_2↑(1) Si(Mn)+2H_2OSiO_2+2H_2↑………… (2) 这种反应的結果,严重的使焊条生产受到限制,輕一些的则在焊条涂料內存在着細小的气孔,使涂料組織疏松化。
In the electrode manufacturing process, paint often add a lot of 鉄 alloy, deoxidation and additional burn alloying elements. At the same time in order to make the electrode has a certain degree of ruggedness and strength, but also must infiltrate a considerable amount of water glass as a coating binder. When the two ingredients are stirred with each other, fermentation occurs, and boiling-like and garlic-like chemical reactions occur. Si (Mh) + 2NaOH + H_2O → Na_2SiO_3 + 2H_2 ↑ (1) Si (Mn) + 2H_2OSiO_2 + 2H_2 ↑ (2) The result of this reaction severely limits the electrode production. In the electrode coating there are small pores, so that the coating material loose.
