Abstract
The invention belongs to the technical field of coal mine transfer piping and discloses a method for preparing a steel-belt occlusion welding plastic-coated composite pipe. The invention is characterized in that the steel-belt occlusion welding plastic-coated composite pipe comprises a pipe of which the two ends are welded with a flange plate, the pipe is formed by spiral winding galvanized steel belts, the adjacent galvanized steel belts are occluded and welded into a whole, and an inner wall and an external wall of the pipe are respectively provided with an inner plastic-coated layer and an external plastic-coated layer; during the preparation, the galvanized steel belts are spirally wound, and occluded with each other, occlusion seams are welded, the flange plates are welded on the both ends of the pipe, the inner plastic-coated layer and the external plastic-coated layer are coated on the inner wall and the external wall of the pipe; and the pipe is subjected to levelling and curing process. The steel-belt occlusion welding plastic-coated composite pipe provided by the invention has low use cost; and the occluding position of the adjacent galvanized steel belts is airtight and air-proof and serves as a reinforcing rib; and the whole tube strength is increased, thereby being capable of bearing higher negative pressure and having the advantages of high corrosion resistance and antistatic behavior and long service life.
Description
Technical field
The invention belongs to colliery conveyance conduit technical field, relate in particular to a kind of method for preparing steel-belt occlusion welding plastic-coated composite pipe.
Background technology
Ventilating system under coal mine, the system that draws out methane, whitewashing system, water drainage-supply system need to use a large amount of conveyance conduits, and current conveyance conduit adopts stainless steel tube, seamless steel pipe, PE pipe, pvc pipe or glass reinforced plastic pipe mostly.Though stainless steel tube, seamless steel pipe intensity are big, the use cost height, and because the colliery subsurface environment is abominable, and stainless steel tube or seamless steel pipe easily are corroded, service life is shorter.Though PE pipe, pvc pipe or glass reinforced plastic pipe cost are lower, antistatic behaviour is poor, is easy to generate the crack in construction, and safety in production is caused certain threat.
Summary of the invention
The deletion of this section.
The technical problem to be solved in the present invention just provides a kind of method for preparing steel-belt occlusion welding plastic-coated composite pipe.
The deletion of this section.
The deletion of this section.
For addressing the above problem, the technical solution used in the present invention is, steel-belt occlusion welding plastic-coated composite pipe comprises that two ends are welded with the body of ring flange, body is entwined for the galvanized steel strip spiral, adjacent galvanized steel strip is welded into one with bite, the inside and outside wall of body is respectively arranged with internal plastic coating layer, outer coating layer, and the preparation method comprises the following steps:
The first step is twined galvanized steel strip spiral on spiral interlock machine becomes body, makes the mutual interlock of adjacent galvanized steel strip, with bonding machine the interlock seam welding is carried out in interlock place of adjacent galvanized steel strip simultaneously and is handled;
Second step is at body two ends difference welding flange;
The 3rd step was sent body into heating furnace and is heated to 90 ℃---and 250 ℃;
The 4th body of step after will heat delivered to fluid bed, sprays PE modified powder coating respectively at the inside and outside wall of body, makes the inside and outside wall formation internal plastic coating layer of body, outer coating layer;
The 5th step carried out levelling with body and solidifies processing.
Its additional technical feature is: described bonding machine is provided with the ointment application device;
Described PE modified powder coating includes following materials in weight portion:
Steel-belt occlusion welding plastic-coated composite pipe provided by the invention compared with prior art, body is entwined for the galvanized steel strip spiral, adjacent galvanized steel strip is welded into one with bite.The use cost of galvanized steel strip is significantly less than the use cost of stainless steel tube, seamless steel pipe, and adjacent galvanized steel strip is welded into one with bite, then its interlock place was not only airtight air tight but also play the reinforcement effect, and whole body intensity strengthens, and can bear high negative.And spraying the PE modified powder coating that is made of high density polyethylene (HDPE), low density polyethylene (LDPE), red phosphorus, antimony oxide synergistic flame retardant, conductive black, compatilizer respectively, the inside and outside wall of body forms internal plastic coating layer, outer coating layer, PE modified powder antistatic property is good, and the sheet resistance of internal plastic coating layer, outer coating layer can be reduced to 3.0X10
4, fire resistance can reach the UL94-V0 level, can satisfy standard and requirement that the colliery draws out methane, and adopts phosphorus flame retardant, good flame retardation effect, does not produce toxic and harmful, very environmental protection.Make corrosion resistance, the antistatic behaviour of steel-belt occlusion welding plastic-coated composite pipe improve greatly, useful life prolongs greatly.And the thickness of galvanized steel strip is 0.5---2.0mm then greatly reduces the weight of body.In addition, the ointment application device is installed on the welding gun next door on the bonding machine, earlier galvanized steel strip is coated with cream and handles before welding, and the unrestrained solder joint in welding back can easily be swept.Do the spiral steel pipe inner surface that both can make after the moulding like this and preserve from, cleared away road for next process-pipe plastic coating again.
