Description

Cigarette flame retardant performance test device

technical field

The utility model belongs to the technical field of cigarette production, in particular to a test device for the flame-retardant performance of cigarettes.

Background technique

According to statistics, the fires caused by smoking account for a large proportion (about 20%) in major fire accidents all over the world in recent years. For this reason, the United States began to conduct research on the test methods for the flame retardant performance of cigarettes in the 1990s. Prior to this, the National Institute of Standards and Technology had formulated two methods: one was the imitation burning method, which placed the lit cigarette on three different standard fabrics, and if the charred part spread to 10 mm of the cigarette Otherwise, the flame retardant performance of the cigarette is considered to have failed; the other is the cigarette extinguishing method, the lit cigarette is placed on a substrate composed of 3, 10 or 15 layers of ordinary filter paper, and if the cigarette burns the entire length, the cigarette is considered to be flame retardant. Combustibility failure. Research on flame-retardant cigarettes is currently a hot topic in the field of international tobacco research. The preparation of flame-retardant cigarettes is closely related to the research on the test methods for the flame-retardant properties of cigarettes. Moody Paper, Austria's Wattens Paper, produces flame-retardant cigarette paper that uses reduced airflow to control the cigarette burning process. New flame-retardant cigarettes developed by Philip Morris could reduce fires caused by smoking. The research on flame-retardant cigarettes in my country has just started. According to the cigarette industry standards in my country, when the cigarettes are still burning, there must be no flame-out of the cigarettes. This shows that almost all domestic cigarettes can burn completely, do not have flame-retardant properties, and do not meet the current international requirements for flame-retardant cigarettes (the proportion of complete combustion is not more than 25%). Therefore, the export of domestic cigarettes is blocked, forcing domestic cigarettes to Manufacturers have to conduct research on the flame retardancy of cigarettes. At present, there is no device for pre-delivery testing of the flame retardancy of cigarettes in major domestic cigarette factories.

Utility model content

By adopting the above-mentioned technical scheme, when the utility model is in use, the transparent cover is first removed, then the cigarettes are lit, and then the burning cigarettes are placed on the filter paper, and the filter tip is inserted on the pricking needle, and all the cigarettes are lighted. After placing it, finally put the transparent cover on the support plate. In this way, the burning state of the cigarette on the surface of the filter paper can be observed through the transparent cover. Since the inside of the transparent cover is a closed cavity, it is necessary to adjust the air intake into the transparent cover by pushing and pulling the valve plate. The air entering upwards through the through hole does not support the combustion of cigarettes, but it can avoid cigarette sticking caused by insufficient air. Automatic extinguishing occurs. Filter paper is a kind of flammable material, and it is stacked in layers on the base plate. By observing the flame retardancy of the burning cigarette, see if it can ignite the filter paper and whether the cigarette is extinguished. If the cigarette can't ignite the substrate in this environment, after many tests, the flame extinguishing rate of the cigarette reaches more than 75%, it can be considered that the cigarette is safe and has flame retardant properties. On the contrary, it does not have flame retardant properties.

Through holes are set on the support plate and the opening size of the through holes is adjusted through the valve plate, which can simulate the flame retardancy performance of cigarettes being discarded on combustibles in indoor, outdoor and windy environments. The cooperation of the positioning ring and the transparent cover can ensure that the transparent cover is placed on the support plate more firmly, avoiding the transparent cover from being knocked down and broken, and improving the sealing performance. The cooperation of the positioning sleeve and the column not only ensures that the bottom plate is placed firmly and horizontally on the column, but also allows the bottom plate to be removed, which is convenient for dumping and cleaning the soot after burning the cigarette.

The utility model is simple in structure, easy to operate and easy to control. It simulates the discarding of cigarettes on combustibles, and simulates various environments of discarding. Improvement of flame retardancy provides reference.
