Description

Technical Field

[0001] The utility model relates to the technical field of nylon manufacturing, and particularly relates to a nylon flame resistance testing device. Background Art

[0002] Nylon is a synthetic fiber. Since various materials can be added to nylon, nylon has various physical properties. Among them, this type of product has a wide range of uses and is a good material for replacing metals such as steel, iron, and copper with plastics. It is an important engineering plastic; cast nylon widely replaces wear-resistant parts of mechanical equipment and replaces copper and alloys as wear-resistant parts of equipment. It is suitable for making wear-resistant parts, transmission structure parts, household appliance parts, automobile manufacturing parts, screw anti-mechanical parts, chemical machinery parts, and chemical equipment. Such as turbines, gears, bearings, impellers, cranks, instrument panels, drive shafts, valves, blades, screws, high-pressure washers, screws, nuts, sealing rings, shuttles, sleeves, bushing connectors, etc.

[0003] In modern production, nylon has different physical properties due to various added materials, such as wear resistance, high hardness, anti-deformation, etc. Among them, when the added materials are shaped by a mold, the flame resistance of nylon is also the most common type. When detecting the flame resistance of nylon, the corners of nylon will be burned for a long time to observe the burning situation at the corners of nylon, see if there is a dripping situation, and then judge the flame resistance of nylon by observing how long it takes to extinguish after burning.

[0004] However, in the actual application process, for the combustion test of nylon, most of the existing equipment uses a clamping device in cooperation with a flame device. The flame device is located below the clamping device and can move. However, when the existing equipment burns, it will detect whether there is a dripping situation of nylon. If nylon is unqualified, dripping will occur, and these drippings may hit the flame outlet of the flame device, affecting the test structure and posing a risk of accidents.
