specific Embodiment approach

[0029] Before the detection starts, confirm whether there is a strong light source at the same level as the detection mechanism in the nearby environment. If it needs to be removed, place the quartz glass plate 6 on the glass plate base 7 and fix it on the platform through the glass plate base support 8 On the end far away from the electric control box 2, the metal dust cover 9 is covered on the ignition source application mechanism, and the candle holder 17 is exposed. There is a long and narrow groove 10 on the metal dust cover 9, so that the guide rod 11 can drive the candle holder. 17 to move, and ensure that as little dust as possible enters the ignition source applying mechanism. When the detection starts, put the candle in the candle positioning ring 20 on the candle holder 17, and install the sleeve 21 at one end of the candle holder 17 in the guide rod 11. When adjusting the candle holder 17 to a proper position, roughly adjust the vertical height of the candle tip , ...

Abstract

The invention discloses a tester of inflammability of foamed aerosol, comprising an ignition source applying mechanism, a flame detecting mechanism and a platform. An electric cabinet is installed at one end of the platform and the flame detecting mechanism is fixed at the other end of the platform. The ignition source applying mechanism is installed between the electric cabinet and the flame detecting mechanism. The tester has high degree of detection automation, realizes automatic ignition and detection of the samples, can detect the flame intensity and the duration and fill up the blank in the domestic technology of detecting the foamed aerosol; the tester has wide applicable range and realizes detecting various foamed aerosol, such as the foamed aerosol, pasty aerosol, powdered aerosol, liquid aerosol and the like; the tester adopts the automatic detection device, is fast in detection, can continuously work and is strong in safety in the detection process; and the tester has high detection accuracy and overcomes the detect that the traditional artificial detection height and duration are incorrect.

Description

technical field [0001] The invention relates to a detection device, in particular to a foam aerosol flammability tester. Background technique [0002] Foam aerosols are dangerous goods in international trade. The "Recommendations on the Transport of Dangerous Goods: Manual of Tests and Standards" issued by the United Nations requires that foam aerosols be tested for flammability and relevant test standards have been formulated. The Foam Aerosol Flammability Tester is used to determine the flammability of foam aerosol products in order to assess the relative fire hazard. [0003] At present, my country's verification methods for foam aerosols have a low degree of automation, mostly manual operations, low measurement accuracy, low measurement efficiency, and poor safety. With the implementation of new standards, they no longer meet the verification requirements; There is no similar device yet. Contents of the invention [0004] In view of the deficiencies in the detection m...
