Abstract

The invention relates to a method and an apparatus for measuring the gas forming quantity of calcium carbide by using a single calibrating weight method, belonging to the technical field of chemical detection. The apparatus for measuring the gas forming quantity of calcium carbide by using a single calibrating weight method comprises a weight weighing machine, a reactor and a gas purifier, wherein a gas inlet of the gas purifier is connected with a gas outlet of the reactor; the reactor and the gas purifier are arranged on the upper part of the weight weighing machine; and the weight weighing machine weighs the weight of the reactor and the gas purifier. In addition, the invention also provides a method for detecting the gas forming quantity of the calcium carbide by utilizing mass variation values before and after the weighed calcium carbide reacts with water. The invention has accurate measurement data, simple and convenient operation method, small volume of the measurement device, low price, convenient use and verification and convenient generalization and popularization.

Description

technical field

[0001] The invention relates to a method and an instrument device for measuring the gas generation of calcium carbide by a single-calibration gravimetric method, belonging to the technical field of chemical detection. Background technique

[0002] At present, the production, trade and use units of calcium carbide in China are basically not standardized in the measurement of gas generation. Some units and individuals even judge the quality by visually observing the intensity of the reaction between calcium carbide and water, resulting in the above situation. The reason is that the traditional measurement method is based on the volume of acetylene gas generated to judge the amount of calcium carbide gas generated. Since the measured gas volume is easily affected by various external conditions, this measurement method has great limitations.

[0003] According to the national standard GB 10665-2004 of "Calcium Carbide (Calcium Carbide)", the gas output of calcium...
