溶解热法测定水化热所使用的仪器中有些配件特别容易损坏,损坏后不能维修,而且更换成本比较高,更换后续工作较为复杂,影响正常试验进程。本文阐述了贝克曼温度计包裹保护方式的改进,通过改进,延长了其使用寿命,提高了试验的准确性,降低了试验消耗。1改进前的包裹保护状况如果按照国家标准,用石蜡包裹保护,因为石蜡容易脱落,为了保证温度计始终处在安全完好的保护状态,必须经常进行重复的包裹,同时还必须重新标 Dissolved heat method hydration heat used by some of the instruments are particularly vulnerable to damage, damage can not be repaired, and replacement costs are relatively high, replacing the follow-up is more complex, affecting the normal test process. This article expounds the improvement of Beckmann thermometer package protection method, improves its service life, improves the accuracy of test and reduces the test consumption. 1 before the improvement of parcel protection status If in accordance with national standards, with paraffin wax protection, because the paraffin wax off easily, in order to ensure the thermometer is always in safe and well protected state, the package must be repeated often, but also must be re-standard
