Description
Technical field
The utility model relates to a kind of multiple tube, relates to a kind of antiseptic and rustproof pressure piping particularly.
Background technique
Pressure piping refers to and utilizes certain pressure, for carrying the tubular equipment of gas or liquid.The steel pipe layer (or claiming " inside liner ") that existing pressure piping is made up of stainless steel usually and the shell of carbon steel material are composited, interior pipe has certain anti-corrosive properties, but outer field anti-corrosive properties are poor, easily cause pipeline breaking, not only affect thermal-insulating waterproof performance and the aesthetic measure of pipeline, also can reduce the working life of pipeline.
Prior art CN201133519Y disclose to have concurrently inside and outside one anticorrosion, intensity is high, resistant to elevated temperatures " stainless steel carbon steel-glass fibre reinforced plastic composite pipe ", it comprises inside liner, mesosphere and enhancing anticorrosive coat, wherein inside liner is made up of stainless steel material, mesosphere is arranged on the outside of inside liner, it is made up of carbon steel material, strengthening anticorrosive coat is then by the outside of glass fiber winding in mesosphere, is then formed with unsaturated polyurethanes solidifying.Prior art CN103629446A discloses a kind of low-lying corrosion resistant alloy corrosion-resistanting insulation pipe, and it is made up of steel pipe layer, multicomponent alloy anticorrosion layer, polyurethane insulation coating and protective polyethylene layer.Still there is deficiency or the defect of the aspects such as the feature of environmental protection, physical stability, heat insulation effect, corrosion resistance in pipeline configuration disclosed in above-mentioned prior art, urgently the pressure piping structure of development of new is to solve the problem.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of novel antiseptic and rustproof pressure piping is provided, there is excellent anticorrosion, antirust, sun-proof performance, have again the advantages such as flame retarding, heat insulating ability, mechanical property, water proofing property, the feature of environmental protection, physical stability concurrently simultaneously.
For achieving the above object, the utility model adopts following technological scheme:
A kind of antiseptic and rustproof pressure piping; described pressure piping comprises pressure tube tube layer (or claiming " inside liner "), complete water base hard foamed polyurethane layer and sun-proof paint protective layer from inside to outside; wherein, described complete water base hard foamed polyurethane layer passes through spray coating foaming direct forming in described pressure tube tube layer.
In the utility model, the thickness of described complete water base hard foamed polyurethane layer is 2-5cm, is preferably about 3cm.
Described complete water base hard foamed polyurethane layer, directly (by the form of spraying, through foaming) to form in pressure tube tube layer and to fit tightly with it, without the need to being prefabricated into special shape, also fit tightly with pressure tube tube layer without the need to being realized by tackiness agent, be suitable for the convenience that Pressure Piping Engineering site operation installs streamlined operation.
The important technological parameters of described complete water base hard foamed polyurethane layer comprises: density of material 55kg/m
3thickness is 2-5cm, elongation at break and drawing coefficient are respectively 16.44%, 40.4kPa (GB/T6344), water absorption rate 3vol% (GB/T 8810), hydrophobic rate 99.6% (GB/T 10299-1988), thermal conductivity 0.04W/ (mK) (GB/T 10291-1988), total carbon content TVOC 333.1 μ gC/g (VDA277), fire-protection rating core B1, B2 level, composite A-grade.
Described complete water base hard blown polyurethane materials is the complete water base hard blown polyurethane materials of richness god adopting Fu Shen company to rely on North America and the exploitation of European high performance polymer material application technical research center research and development strength.Specifically, it is stoste based on polyethers, polyester, take amine as catalyzer, with water-soluble silicon-carbon type silicone oil (abbreviation organosilicon) for foam stabilizer, being stabilizer with deionized water, take phosphorus-containing compound as the polymeric compound that the polyether polyols raw polyol that is mixed to form of fire retardant and isocyanates carry out exothermic reaction generation.This material is complete water base foaming system, this make shaping after macromolecular material hydrophilic radical distribute more balanced in the material with hydrophobic radical; In addition, this material is hole-closing structure, and thermal-insulating waterproof heat-shielding performance is superior, without Small molecular noxious gas emission, and strong mechanical property, durable in use, with the building same life-span.
Remarkable result of the present utility model is:
Pressure piping of the present utility model has excellent anticorrosion, antirust, sun-proof performance, has again the advantages such as flame retarding, heat insulating ability, mechanical property, water proofing property, the feature of environmental protection, physical stability concurrently simultaneously.The flame retarding of described pipeline can reach B2 rank, thermal conductivity is less than or equal to 0.024W/ (mK), tensile bond strength is more than or equal to 0.10MPa, compressive strength is more than or equal to 0.15MPa, water absorption rate is less than or equal to 3%, dimensional stability be less than or equal to 1.5% and oxygen index be more than or equal to 26%, visible, having excellent flame retarding, heat insulating ability, mechanical property, water proofing property and physical stability etc. concurrently, is the extremely strong anti-corrosion anti-rust material of a practicability.
Compared with conventional pressure pipeline, ducted pressure tube tube layer of the present utility model and complete water base hard foamed polyurethane layer fit tightly, and without the need to passing through tackiness agent, bonding force is strong, antiseptic and rustproof effective; Secondly, the composite structure light weight of pressure tube tube layer and complete water base hard foamed polyurethane layer, can effectively reduce pipeline deformation mechanical load, strengthens overall structure toughness and cracking resistance sex change.
With Conventional insulation as compared with extruded sheet, styrofoam, mineral wool, vitrification micropearl morttar etc.; complete water base hard polyurethane foam thermal insulating material thermal conductivity of the present utility model is little; high insulating effect, makes described pipeline be thermal-insulating waterproof integral structure, low-carbon (LC), green, environmental protection.
The mechanical stretch intensity of complete water base hard polyurethane foam thermal insulating material of the present utility model is high, and optimum with pressure tube tube layer cementability, and with pressure tube tube layer without cold-heat bridge, resistance to cracking is good, free from flaw, and this is that Conventional insulation cannot realize.
The rate of closed hole of complete water base hard polyurethane foam thermal insulating material of the present utility model is high, and can reach more than 92% (GB10799), moisture absorption moisture proofness is good, for pressure piping, can realize thermal-insulating waterproof integration.
Other thermal insulating material relatively, complete water base hard polyurethane foam thermal insulating material of the present utility model forms complete water base hard foamed polyurethane layer by spray coating foaming direct forming in pressure tube tube layer, without the need to being prefabricated into special shape, also without the need to being fitted tightly by tackiness agent and pressure tube tube layer, its convenience in forming materials, construction and installation is its unrivaled advantage.
