Alcohol blowtorch / alcohol burner burning test device model: HAD-CMK-1 1.1 Main uses and scope of application The device is mainly used for non-metal products for coal mines (coil cylinders, air duct coating cloths, conveyor belts, pipes, plastic nets, cables, FRP products, non-metallic casings for instruments and meters, non-metallic materials for coal mines, etc.) ) Flame retardant performance test. This device is available with the following latest standards: MT113 "General test method for flame retardant and antistatic properties of polymer products used in coal mines Judgment rule MT164 "Positive pressure air duct for coal mine" MT165 "Negative Pressure Duct for Coal Mine" MT383 "Technical Conditions for Coating Coats for Coal Mines" GB16413 "Code for inspection of safety performance of glass reinforced plastic products for underground mines" MT147 "Fire-retardant antistatic fabric core conveyor belt for coal mine" MT141 "Plastic top for plastic mesh in coal mine" MT181 "Code for Inspection of Safety Performance of Plastic Pipes for Underground Coal Mines" MT191 "Code for Inspection of Safety Performance of Rubber Pipes for Underground Coal Mines" MT157 "General technical conditions for explosion-proof water tanks and explosion-proof water bags for coal mines" 2.1 Principle The mixed fuel with a capacity ratio of 95% industrial ethanol (GB394) and 5% methanol (GB338) flows through the plastic hose into the preheating section of the alcohol burner, and is heated and vaporized by the preheating section to form a certain pressure of alcohol gas. , sprayed through the nozzle, burning to produce a high temperature flame. According to the standard requirements, the test piece is fixed to the combustion frame, and under the specified flame temperature and flame length condition, the sample is ignited for a certain period of time, the alcohol burner lamp is removed, and the test piece is flamed or flameless. After the test is completed, the smoke exhaust system is activated to exhaust smoke. During the test, the change process of each test piece shall be observed at any time until the flame or flameless combustion of the test piece or the dripping material is extinguished. Depending on the operating state of the alcohol burner, the burner can be tilted at 45° or placed vertically. The burner can be raised and lowered and tilted by 45°. 2.2 Structure The device consists of an alcohol burner burner, a burner base, a sample holder, a fuel bottle, a combustion test chamber, and a smoke exhaust system.
