Problems solved by technology

However, there is no literature report on the measurement device for the heating performance of the chemical reaction designed around the new cigarette
Although the temperature that the heating source can provide when the heating source is activated is reported in the relevant patents of new cigarette products, these patents do not provide any information on the heating performance measurement of the heating source, and it is impossible to determine how to obtain the temperature that the heating source can provide when the heating source is activated. temperature

Embodiment 1

[0022] When measuring the heating performance of the liquid-liquid chemical reaction, first place a certain volume of any one of the two reaction liquids in the polytetrafluoroethylene liner of the reaction vessel, cover the lid and screw it tightly. Then, three thermocouples 3 are fixed into the reaction vessel by threads, and the electrodes of the three thermocouples are located at different depths in the reaction vessel, so as to facilitate testing the temperature change of the liquid during the reaction at three different depths. Then connect the data extension line of the thermocouple to the data acquisition recorder, and turn on the data acquisition recorder and the computer, and the data acquisition starts, so as to ensure that the data acquisition is performed from the beginning of the reaction. Finally, another reaction liquid is injected into the reaction vessel through a syringe, and the syringe is quickly pulled out. The reaction starts, and the three thermocouples ...

Embodiment 2

[0024] When measuring the heating performance of the solid-liquid chemical reaction, at first a certain weight of solid reactant is placed in the polytetrafluoroethylene liner of the reaction vessel, and then another liquid reactant is injected, and other steps are the same as in Example 1 .

Abstract

The invention provides a device suitable for detecting heating performance of chemical reaction raw materials of a cigarette. The device is characterized by comprising a reaction container with a sealing cap and thermocouples arranged in the reaction container, injectors for injecting the reaction raw materials are inserted in the sealing cap, one end of each thermocouple is connected with a data acquisition and recording instrument and a computer through connection wires, the reaction container comprises a polytetrafluoroethylene inner container and a stainless steel casing, and the inner container is a heating performance testing cavity for a liquid-liquid chemical reaction or a solid-liquid chemical reaction. One of two to-be-detected reactants for heating in chemical reactions of the cigarette is put into the reaction container through the device, then the other reactant is injected to have a reaction with the first reactant, heat is discharged, the reaction temperature is detected through the thermocouples and transmitted to the data acquisition and recording instrument and the computer, and the temperature of the reaction can be detected, and the heating effect of the reaction raw materials can be evaluated. The device has the advantages of small error and high detection accuracy.

Description

technical field [0001] The invention relates to a chemical reaction heating temperature testing technology, in particular to a device suitable for testing the heating performance of cigarette chemical reaction raw materials. Background technique [0002] With the change of people's lifestyle and consumption concept, and affected by factors such as tobacco control and public opinion, the development of traditional cigarettes has been more and more restricted. At the same time, under the conditions of tobacco burning, it is very difficult to further significantly reduce the release of cigarette tar and harmful components. Therefore, changing the traditional consumption mode of tobacco burning and smoking, developing new types of cigarettes, and continuing to meet the needs of consumers is an important way to fundamentally break through the bottleneck of the sustainable development of my country's tobacco industry. major strategic deployment. [0003] The new type of cigarette...
