Description
Technical Field
The utility model relates to a needled felt technical field specifically is a compound needled felt that fluorine meisi is high temperature resistant.
Background
The needle felt is a material which is produced by processing the surface of a needle felt produced by polyester staple fiber and polyester twisted yarn through post treatments such as hot rolling, singeing or coating and the like by adopting a non-woven needle-punching process and utilizing fine fiber cloth with fibers which are arranged in a staggered way and uniformly distributed gaps.
The existing composite needled felt is poor in overall high-temperature-resistant effect, short in service life due to the fact that the felt is used in an environment with high smoke temperature, frequent in replacement, increased in use cost and poor in practical effect.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a compound acupuncture felt of resistant high temperature of fluorine meisi to the holistic high temperature resistant effect of the compound acupuncture felt of current that proposes in solving above-mentioned background art is poor, uses under the high environment of flue gas temperature and can cause life weak point, and it is therefore frequent to change, has increased use cost, problem that practical function is poor.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a compound needled felt of resistant high temperature of fluorine meisi, includes the base cloth layer, the outside on base cloth layer is provided with first superfine fiber needled felt layer, the outside on first superfine fiber needled felt layer is provided with high temperature resistant layer, high temperature resistant layer includes the polyimide fibrous layer, the outside on polyimide fibrous layer is provided with polytetrafluoroethylene fibrous layer, polytetrafluoroethylene fibrous layer's the outside is provided with the asbestos fiber layer, the outside on high temperature resistant layer is provided with second superfine fiber needled felt layer, the outside on second superfine fiber needled felt layer is provided with the PTFE layer.
Preferably, the thickness of the first superfine fiber needled felt layer and the second superfine fiber needled felt layer is between 0.6 and 1.5 cm.
Preferably, the layer surface of the high temperature resistant layer is provided with air holes.
Preferably, the thickness of the PTFE layer is between 0.2 and 0.4 cm.
Preferably, the thickness of the high temperature resistant layer is between 1 and 2 cm.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses simple structure, the high temperature resistant layer of constituteing through polyimide fibrous layer, polytetrafluoroethylene fibrous layer and asbestos fibrous layer can improve holistic high temperature resistant characteristic to can improve holistic high temperature resistant effect when using under the high environment of flue gas temperature, the anti high temperature and the corrosion-resistant effect on surface can be strengthened in setting up of cooperation PTFE layer, can avoid like this that the temperature influence reduces holistic life, avoids the operation of frequent change, reduces use cost.
