【摘要】：为解决目前阻化剂只有单一阻化作用的问题,加入一种具有耗氧功能的材料,形成一种具有耗氧和阻化双重作用的脱氧型阻化剂。通过试验的方法,将不同配比的脱氧型阻化剂放置在恒温仪器里测其耗氧时间,得到不同配比的脱氧型阻化剂的耗氧速率与氧体积分数的关系以及耗氧速率的变化规律。改变试验温度,得到脱氧型阻化剂的耗氧速率与氧体积分数的关系以及耗氧速率的变化规律。试验结果表明,氧体积分数越大,耗氧速率越高;随温度的升高,脱氧型阻化剂的耗氧速率在加快;硅藻土的量为0.6 g时,脱氧型阻化剂的耗氧速率最快;无机盐使用量相同时,耗氧速率为v(MgCl_2)v(NaCl)v(KCl)v(CaCl_2),耗氧速率随无机盐使用量的增加而降低,使用0.15 g MgCl_2的脱氧型阻化剂耗氧速率最快。
[Abstract]:In order to solve the problem that the inhibitor has only a single inhibiting action at present, an oxygen-consuming material is added to form a deoxidized inhibitor with both oxygen consumption and inhibition. The oxygen consumption time of deoxy inhibitor with different ratio was measured in a constant temperature instrument. The relationship between oxygen consumption rate and oxygen volume fraction and the change rule of oxygen consumption rate were obtained. The relationship between oxygen consumption rate and oxygen volume fraction of deoxidized inhibitor and the variation of oxygen consumption rate are obtained. The experimental results show that the higher the oxygen volume fraction, the higher the oxygen consumption rate, and the higher the temperature, the higher the oxygen consumption rate is. The oxygen consumption rate of deoxy-type inhibitor is accelerating; when the amount of diatomite is 0.6 g, the oxygen consumption rate of deoxy-type inhibitor is the fastest; when the amount of inorganic salt is the same, the rate of oxygen consumption is v / MgCl _ 2 / KCl _ 2 / KCl _ (+) / CaCl _ 2 / S, and the rate of oxygen consumption decreases with the increase of inorganic salt usage. The oxygen consumption rate of deoxy inhibitor with 0. 15 g MgCl_2 is the fastest.
