Description
Technical field
The present invention relates to inflammable gas, liquid or fluidized solids transfer tube, more particularly to a kind of anti-electrostatic fire retardant
Shaped steel plastic composite.
Background technology
Many inflammable, explosive occasion needs large-scale Pipeline transport gas, even liquid, fluidized solids.Many pipelines
The gas conveyed, liquid or liquefied solid, inherently explosives, inflammable items, such as the various transfer pipelines under mine, such as
The high underground air of firedamp drainage content, blast furnace gas, flyash.Under this occasion, there is higher requirement to transfer conduit, such as
Fire-resistant, prevent electrostatic phenomenon, wear-resisting, anti-leakage etc..So traditional engineering discipline can only use cast iron pipe, or large-diameter steel
Pipe.Its weight is big, and corrosion is too fast, if it is considered that to be directed at use cost too high for friction loss.So needing what is constructed
Occasion is often invested greatly.
In the last few years with material technology, the raising of technique, due to being solved well in pvc pipe road and composite glass steel pipe
Fire-retardant and antistatic problem.The plastic composite pipe of PVC and fiberglass etc has been also widely used under mine and similar
Occasion.By fiber or fabric it is base-material in composite plastic pipe manufacture craft, using thermosetting resin adhesive as adhesive, adds and match somebody with somebody
Fire retardant, antistatic additive, curing agent and inserts composition adhering and solidifying agent, in the coating bonding of tubular mould top winding base-material side
Curing agent, forms the pipeline with prefabricated ring flange fitment combination after final solidification, the structure of pipeline includes three layers：In tubular mould
Even application has the tool that conductive and flame-retarding characteristic thermosetting resin adhesive is formed simultaneously for upper winding fiber or its fabric
There is impervious and anti-wear performance inner liner, wind enhanced fiber on the basis of ring flange mold and inner liner are formed or it is knitted
Even application has the strength layer that conductive and flame-retarding characteristic thermosetting resin adhesive is formed to thing simultaneously, in the table of strength layer
The thermosetting resin adhesive of fiber or its fabric while even application with strong conduction and flame-retarding characteristic of densification is wound on face
Formed surface conductive layer.Due to its low cost, corrosion resistance is strong, service life received the welcome of pole up to 50 years.
But with application, the shortcomings that inner obvious is exposed, as flexural strength is too low, difficulty of construction is larger.Then remove
Also capacity of resisting impact load is poor outside above weakness, and quality is crisp, poor toughness easily causes comminuted breakage in the presence of a harsh environment,
Easily without possessing excellent security, its anti-wear performance is also poor for leakage, for the big gas of dustiness and fluidized solids
Conveying then shows hidden danger clearly disadvantageous and for security.In addition, existing steel-plastics composite pipe, its steel pipe is moulded with inside and outside layer
Material pass through PUR adhering and sealing, easily causes steel pipe and is combined with plastics not firm enough, the particularly time one is grown and cold and hot caused
Under stress, it may occur that separate, slip between steel pipe and plastics, cause steel pipe by corrosion, reduction of service life.
