Abstract
The present invention is one kind of composite metal net reinforced superhigh molecular weight polyethylene GRP pipe for hydraulic conveying of coal cinder, mineral sand, silt and other solid grains. The composite pipe consists of outer casing and inner lining, and features the inner lining formed via hot pressing metal net into polymer material, the outer casing of GRP, and the firm adhesion of the inner lining with metal net exposed in outer surface to the inner surface of the GRP outer casing via epoxy resin adhesive. The composite pipe of the present invention has the advantages of light weight, high strength and anticorrosion, like GRP pipe, and the lining with excellent characteristic of being wear resistant, anticorrosive and antiscaling.
Description
Technical field
The present invention relates to a kind of waterpower carries the wire gaze of wear-resisting, the corrosion resistant of solid particles such as coal ash slag, ore in sand form, silt, resistive connection dirt to strengthen the ultra-high molecular weight polyethylene glass fibre reinforced plastic composite pipe.
Background technique
Distance output need be grown to the lime-ash of afterburnt coal by thermal power plant, thermal power plant's pipeline commonly used carries out the waterpower conveying to lime-ash now, wearing and tearing are very serious in conveying, bend part particularly, with reason the accident that pipeline is worn through and leaks often takes place, emergency first-aid repair is continuous, and this has not only influenced the safety in production operation of thermal power plant, increased Cost of repair and maintenance, lime-ash sewage also usually causes environmental pollution.In addition, when the high lime-ash of line transportation calcium content, metallic conduit internal surface scale formation usually takes place also, cause the pipeline passage section to reduce, flow resistance increases, and also has a strong impact on safe operation of power plant.This fouling usually occurs in the top inner surface of horizontal positioned pipeline and the inboard internal surface of bend pipe, and general now antifriction metal (AFM) pipeline such as wear-resistant alloy cast steel is still had no idea to fouling.To the pipeline with the seawater dredging silt, also have the difficult problem of seawater corrosion especially, the metal species pipeline more has not a particle of way.At present, pottery, glass fibre reinforced plastic composite pipe and ultra-high molecular weight polyethylene glass fibre reinforced plastic composite pipe are arranged, and the former the ceramic plate obscission can occur, and the shortcoming of latter's maximum is easy layering, essence does not cement, and its reason is that the ultra-high frequency molecular weight polyethylene is a kind of hard bonding plastics.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming of prior art, solve the difficult sticking problem of macromolecular material, provide that a kind of wear resistance is good, rotproofness is good, can the resistive connection dirt, the wire gaze of less expensive strengthens the ultra-high molecular weight polyethylene glass fibre reinforced plastic composite pipe again.
Task of the present invention is achieved in that a kind of wire gaze strengthens the ultra-high molecular weight polyethylene glass fibre reinforced plastic composite pipe, it is made up of shell and liner, be characterized in: liner be by wire gaze by hot pressing to the macromolecular material form, shell is a glass fibre reinforced plastics, and the liner that is strengthened by wire gaze has the internal surface implementation bonding connection of certain thickness wire gaze with epoxy adhesive and glass fibre reinforced plastics casing by being exposed to its outer surface.
This programme has solved the macromolecular material of making liner and the problem that is difficult to bond of glass fibre reinforced plastics casing.Make the intrinsic lightweight of the existing fiber reinforced plastic pipe of the present invention, high-strength, the advantage of corrosion resistant, and the liner polymer-material wear-resistant arranged again, corrosion resistant, the good characteristic of resistive connection dirt, can be used as corrosion resistant, wear-resisting, the extraordinary pipeline of the waterpower conveying solid substance particle of resistive connection dirt, for example waterpower is carried ore in sand form, silt, the pipeline of solid particles such as lime-ash, even being mordant seawater, fed sheet of a media do not have any problem yet, and the fiber reinforced plastic pipe internal diameter is made can arrive 3-4 rice greatly, therefore the appearance of this composite pipe, to the heavy caliber corrosion resistant, wear-resisting pipeline is made and has been opened up good prospect, has filled up the heavy caliber corrosion resistant, the blank that abrasion-proof pipe is made.
