The metal tube has the advantages the metal tube with a ceramic particle strengthened composite material lining has excellent wear resistance and corrosion resistance, service life is greatly prolonged, raw materials of the metal tube are easy to be obtained, and further, the metal tube is simple in manufacturing process, lower in cost, convenient for actual application and mass production of factories and obvious in economic benefit.
Description
Technical field
The utility model relates to a kind of composite wear-resistant tube.It specifically is a kind of ceramics particle strengthened composite material lining metal tube.
Background technique
In various industry fields such as mining, metallurgy, have that for example pit backfill of many processes, mineral transport, waste disposal, the husky mud of excavation, clean ore, transport coal ash etc. and all need the slurry of carrying a large amount of solid materials or solid-liquid to mix at a distance, these materials or slurry contain the bulk or the granular solids of a large amount of high hardness, and therefore corresponding conveyance conduit is faced with serious wear problem.In these commercial Application, not only require conveyance conduit intensity height, good toughness, also need to improve as far as possible the wear-resisting property of pipeline.The pipeline wear-resisting property of single metal material preparation improves very limited, and therefore, NEW TYPE OF COMPOSITE inner liner metal pipeline is one of measure that solves pipeline wear resistance and good construction performance.Person skilled has been carried out big quantity research and innovation in this field both at home and abroad in recent years.
Domestic patent of invention CN1072007 has proposed a kind of wear-and corrosion-resistant composite steel pipe and manufacture method thereof of cast stone liner, its characteristics are that be the liner that base-material mixes the cementitious matter formation that cohesiveencess is good, flexible has anticorrosion antiwear at common steel tube internal fixation one deck with the high cast stone material of wear-resistance and anti-corrosion performance, have improved the wear-resisting and anticorrosive property of pipeline.Its defective is that the cast stone liner pipe is comparatively heavy, and transportation and installation are all difficult; And cast stone liner easy breaking releasing when pipeline is subjected to STRESS VARIATION violent.
Domestic utility model patent CN201225460 has proposed a kind of stupalith inner liner abrasive resistant pipeline, its characteristics are that liner is the bulk ceramics pipe, between internal lining pipe and outer sleeve, be provided with the packing layer of forming by heatproof glue and thermal insulating filling, the wear-resistant and decay resistance of pipeline is significantly strengthened.Its defective is that the preparation process of ceramic-lined pipe is very complicated, with high costs; And stupalith fragility is big, " avalanche type " takes place easily come off, rupture; Because outer sleeve and internal lining pipe difference of thermal expansion coefficients are very big, the as easy as rolling off a log inner and outer pipes that causes comes off under high-temperature condition.
Domestic patent of invention CN2219411 has proposed a kind of bimetal composite wear resistant tube, and its characteristics are that inside liner adopts cast iron materials, have good wear resistance energy and toughness and tenacity, and the internal and external layer material structure is close, and thermal compatibility is good, long service life.Its shortcoming is that compound lining thickness is big, and liner and outer wall are difficult for realizing metallurgy combination that in corrosive atmosphere, corrosive liquid easily corrodes the pipe outer wall fast by the slit and leaks.
U.S. patent of invention US4101623 has proposed a kind of abrasion-proof pipe manufacture method that adopts thermosetting plastics as inside liner, has more effectively improved the wear-resisting property of pipeline, and has reduced manufacture cost.Its defective is that the thermosetting plastics decay resistance is relatively poor, and easy ageing failure; Combination force between plastics and steel pipe is lower, deforms easily and comes off.
Though above-mentioned multiple tube has improved the abrasion condition of conventional metals pipeline in the conveying material process in various degree, all have and be difficult to the defective that overcomes separately.
Summary of the invention
The utility model aims to provide a kind of ceramic particle reinforced composite liner metal tube, has higher wear resistance and long working life.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of ceramics particle strengthened composite material lining metal tube, comprise outer sleeve, and it is characterized in that: outer sleeve is the metal tube of Stainless Steel Tube, alloy steel pipe or other types; On the inwall of outer sleeve, be consolidated with the ceramics particle strengthened composite material lining layer.The ceramics particle strengthened composite material lining layer is bonded on the inwall of outer sleeve by the rubber-metal Bond that is coated on the outer sleeve inner wall.The utility model has following advantage compared to existing technology:
A. inside liner adopts the polyurethane-base ceramic particle composite material, and its wear resistance compares other inside liner materials with corrosion resistance and single polyurethane material has very big lifting, and pipeline is improved working life;
B. polyurethane matrix adopts 4 in the inside liner composite material, and 4 '-'-diphenylmethane diisocyanate (MDI) system improves combination force by the rubber-metal bond between inside liner and the metal pipe internal wall, has improved the defective of prior art interface binding power difference;
C. this invention raw material is easy to get, and manufacturing process is simple, and cost is lower, is convenient to factory's practical application and batch process, remarkable in economical benefits.
The beneficial effects of the utility model are: by introduce polyurethane-base ceramic particle composite material inside liner, the wear resistance and the working life of greatly having improved metallic conduit in metallic conduit.
Below in conjunction with drawings and Examples the utility model is further specified.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A sectional drawing of Fig. 1.
Among the figure: 1, outer sleeve, 2, the rubber-metal bond, 3, inside liner.
As depicted in figs. 1 and 2, ceramics particle strengthened composite material lining metal tube is made up of stainless-steel seamless pipe outer tube 1 and the ceramics particle strengthened composite material lining layer 3 that is cemented on the outer sleeve inner wall. For improving the adhesion between inner liner and the outer tube, between outer sleeve inner wall and inner liner, also be coated with rubber-metal binding agent 2.
Embodiment
The manufacture method of composite material lining metal tube is, earlier at the even brushing one deck of stainless-steel seamless pipe inwall rubber-metal Bond, places it in then on four cylinders in the large-scale baker, and one of them cylinder is with 300 rev/mins rotational speed.When treating that outer steel pipe is heated to 90 ℃, keep constant temperature, stretch into the slotted cast pipeline in below, the liquid pouring material is injected in the gate spool road under certain pressure, the liquid pouring material is slotted along the below extrude and attached on the outer sleeve inner wall.
After cast thickness reaches requirement, stop to feed the liquid pouring material and withdraw the cast pipeline, continue centrifugal rotation and stop the cylinder rotation after 1 hour.Temperature is risen to 120 ℃ and be incubated 20 hours, make the full cure of polyurethane-base ceramic particle composite material, form stable solid-state inside liner.
