Detailed Description
The present invention will be further described with reference to the following examples.
Example 1
As shown in fig. 1-2, a device for detecting the combustion performance of a plastic film comprises a base plate 1, a sliding plate 2, an igniter 3 and two groups of fixed supports; the fixed brackets are symmetrically arranged on two sides of the bottom plate 1 respectively; the sliding plate 2 is arranged on the bottom plate 1 in a sliding manner and is arranged between the two groups of fixed brackets; an igniter 3 is placed on the slide plate 2 for igniting the plastic film. The setting of fixed bolster can be fixed with plastic film, utilizes the igniter 3 of placing on slide 2, and the removal slide 2 drives igniter 3 and removes, makes plastic film ignite the end and slowly is close to igniter 3. If necessary, the igniter 3 is moved forward according to the change of the contact position, and the edge of the ignited sample is kept in contact with the flame of the igniter 3. The igniter 3 is an alcohol lamp, and in other alternative embodiments, the igniter 3 may also be a candle, a kerosene lamp, or the like. Two guide rails are arranged on the bottom plate 1, and the sliding plate 2 is arranged between the two guide rails to complete sliding arrangement and ensure stable movement. In other alternative embodiments, the bottom plate 1 is provided with a sliding groove, and the sliding plate 2 is provided with a boss which is slidably arranged in the sliding groove.
In the above arrangement, the fixing bracket includes two screws 4 and a fixing plate 5; the fixing plate 5 is disposed on the screw rod 4 by a nut. The whole fixed plate 5 is arranged in a convex shape, so that the plastic film is convenient to fix, and the plastic film can be guaranteed to be tiled. The plastic film is arranged on the fixed plate 5, and the height of the plastic film can be adjusted according to the flame height of the igniter 3, so that the height of the plastic film is positioned at the flame center position of the igniter 3.
One side of the sliding plate 2 is provided with a handle 6 through a vertical plate. Wind shields 7 are arranged on the periphery of the bottom plate 1; an opening is formed in one side of the wind shield 7 and matched with the sliding plate 2, and is used for shielding wind during testing, so that the external wind is prevented from influencing the combustion effect of the igniter 3 and the plastic film.
