Background technique
Currently, carbon fiber heating cable is widely used to the industrial circles such as petroleum, chemical industry, steam power plant and fire protection pipeline etc.
Public sphere.Carbon fiber heating cable, including carbon fiber exothermic part, are surrounded by protective case outside the heater, outside the protective case
It is surrounded by insulating layer, the insulating layer is made of inner insulating layer and external insulation layer, and shielded layer, the screen are surrounded by outside the external insulation layer
It covers and is surrounded by threading casing outside layer.
And penetration pipe can be divided into according to flame retardant property that halogen is fire-retardant and halogen-free flameproof two types, wherein though there is halogen fire-retardant
Right additive amount is small, flame retardant property is high, but can volatilize a large amount of poison gas when its burning, causes " secondary disaster ".Halogen resistance
The matrix of combustible material is usually metal oxide, metallo-organic compound, hydration metal hydroxides etc., and fire retardant is hydroxide
Magnesium, aluminium hydroxide, antimony oxide, compound of molybdenum etc..If flame retardant formulations are unreasonable, flame retardant effect is not satisfactory, if
If improving flame retardant property by increasing additive amount, and the cost of product can be improved and affect the bending performance of material,
It is difficult to the regulation being up to state standards.
Summary of the invention
