三、工作原理:

★利用乙二醇与水泥熟料中的游离氧化钙反应后,溶液的电导率与游离钙含量成一定的比例关系,通过电导率的测量间接反应出水泥熟料中游离氧化钙含量。本仪器需通过标定才能达到**测量的目的。

★有机溶液乙二醇在高温下与水泥熟料中的游离氧化钙反应:

        (CH2OH)2+CaO→(CH2O)2Ca+H2O

 上式反应成的乙二醇钙按下式在乙二醇中离解:

        (CH2O)2Ca→(CH2O)22-Ca+Ca2+

★乙二醇离子和钙离子在溶液中导电,导电程度与游离氧化钙含量存在一定的关系。通过对溶液导电率的测量可间接测量出水泥熟料中的游离氧化钙的含量。

★在水泥游离氧化钙快速测定仪使用中,电**的清洁度对测量结果的准确具有较大的影响。因此,在仪器的使用过程中应保持电导电**的清洁。

以单片微型计算机芯片为A控制芯片,采用大规模集成电路。经严谨的科学设计,完成对恒温槽的恒温控制。电导电**加载电源,电导率的测量、键盘管理、

Third, the working principle of cement free calcium oxide analyzer:

★ Using ethylene glycol to react with free calcium oxide in cement clinker, the electrical conductivity of the solution has a certain proportional relationship with the free calcium content, and the free calcium oxide content in cement clinker is indirectly reflected by the measurement of the conductivity. This instrument needs to be calibrated to achieve the purpose of ** measurement.

★ Glycol in organic solution reacts with free calcium oxide in cement clinker at high temperature:

        (CH2OH) 2 + CaO → (CH2O) 2Ca + H2O

 The calcium glycol reacted by the above formula dissociates in ethylene glycol as follows:

        (CH2O) 2Ca → (CH2O) 22-Ca + Ca2 +

★ Ethylene glycol and calcium ions conduct electricity in the solution, and the degree of conductivity has a certain relationship with the content of free calcium oxide. The content of free calcium oxide in cement clinker can be indirectly measured by measuring the conductivity of the solution.

★ In the use of cement free calcium oxide rapid tester, the cleanliness of electricity has a greater impact on the accuracy of the measurement results. Therefore, the electrical conductivity should be kept clean during the use of the instrument.

A single-chip microcomputer chip is used as the A control chip, and a large-scale integrated circuit is used. After rigorous scientific design, the thermostatic control of the thermostatic bath is completed. Electrically conductive ** Loading power, conductivity measurement, keyboard management,


四、注意事项:

★待测的水泥熟料样品一定是研磨至全部通过孔径为0.008的筛子的粉末,否则影响反应速度,导致测量结果偏低。

★所用的50ml反应瓶一定是干燥的,测定过程中不能带进水。否则影响反应速度,导致测量结果偏低。

★电导电**在测量过程中可浸泡在纯乙二醇溶液中,并应经常更换乙二醇溶液,电**使用中可能在铂电**表面沾有水泥样品,因而影响测量结果,因此需用稀盐酸和蒸馏清洗,一般1——2次/周

Fourth, the matters needing attention of cement free calcium oxide analyzer:

★ The cement clinker sample to be tested must be a powder that has been ground to all through a sieve with a pore size of 0.008, otherwise the reaction speed will be affected and the measurement result will be low.

★ The 50ml reaction bottle used must be dry, and water cannot be brought in during the measurement. Otherwise, the reaction speed will be affected, resulting in low measurement results.

★ Electrical conductivity ** can be immersed in pure ethylene glycol solution during the measurement process, and the ethylene glycol solution should be replaced frequently. Electricity may use cement samples on the surface of platinum electricity ** during use, thus affecting the measurement results Therefore, it needs to be washed with dilute hydrochloric acid and distillation, generally 1-2 times / week
