Description
Technical field
The present invention relates to production of resins technical field, specifically a kind of resin material production based on the stretching method that hangs down vertically again
Line.
Background technique
It is well known that product made of glass fiber reinforced epoxy resin (or unsaturated polyester (UP)) is also known as epoxy resin
Tubing, high temperature resistant corrosion-resistant with its, radiation hardness and density is small, rigidity is good, intensity is high are widely used in national defence, industrial and agricultural production
In people's daily life, as guided missile shell case and satellite fairing, the heat insulation material of spaceship, aircraft and naval vessel shell
Body, fin and propeller etc., glass fiber reinforced epoxy resin (or unsaturated polyester (UP)) product are mainly used in civilian industry
In pressure vessels and pipes, anticorrosion container, automobile instrument panel, bumper, electrical insulation, yacht etc., glass fiber reinforcement epoxy
When tree (or unsaturated polyester (UP)) product is mainly used for various pipelines, production technology is mainly included on glass fibre and coats
Epoxy resin (perhaps unsaturated polyester (UP)) will be coated with the glass of epoxy resin (or unsaturated polyester (UP)) by pressure roller and winding axis
Glass fiber is wound layer by layer, after thickness to be wound reaches the requirement of tube wall, glass fiber reinforced epoxy resin (or insatiable hunger
And polyester) shell i.e. produce, then carry out hot setting, final production tube can be obtained.But in production process
In, during the most common problem is wound around, since air exists, and bubble or cavity is formed in interlayer, seriously affect production
Quality and performance cause product qualification rate not high, and production cost increases.And glass fibre after carrying out sizing step away from
From winding roller, there are also a distances, in this section in transmission process, often will appear the phenomenon that glue is aggregated, cause in the later period
Glue is unevenly distributed in the overshoot of winding, will appear small gas chamber in tube wall after carrying out drying and processing, these are all serious
Influence the product quality and service life of production tube
Another is common for pulling pultrusion technique, and the reinforcing materials such as felt, cloth, continuous zero twisted yarn are mainly passed through infiltration tree
Rouge then by pipe mold, then is pulled through dragger, to continuously produce the unrestricted epoxy resin of length
The products such as tubing.
The mechanical strength of epoxy resin is mainly to be determined by fiber, and the main function of matrix resin is that each bundle fiber is glued
Knot together, carries out the transmitting of ess-strain.If bonding bad between resin and fiber, will result in stress cannot be effective
It transmits between the fibers, it is difficult to play the effect that fiber undertakes Main Load.
Below by taking the application of epoxy resin in insulating pole tower and petrochemical pipe as an example:
One, insulating pole tower:
In recent years, due to the expansion of glass fiber compound material application field, with it is its it is light-weight, intensity is high, anti-gas
Wait the excellent characteristics such as aging, corrosion resistance be strong, power communication field of power transmission have glass fiber compound material is used for it is defeated
In the products such as electric pole, tower, the insulating properties of route can be increased substantially, greatly improves the resistance to pollution flashover of route, ice sudden strain of a muscle, wind-deviation, resistance to
Thunder is horizontal.The performance of composite material transmission tower and use are gradually by the attention of power domain.
And be mostly at present single rod type by the shaft tower of composite Materials Design, conveying voltage class is confined to 35KV or less.
Higher voltage grade can not be still applicable in, and the particular/special requirement of high pressure level is not achieved in bearing capacity, thus makes composite material pole tower
Development is restricted.
Two, petrochemical pipe:
The more steel pipeline anti-corrision layer of domestic application has asphalt, PE jacket and PE foam jacket, epoxide coal bituminous, coal tar
Oily enamel paint, epoxy powder and three-layer composite structure etc., promoting and applying two kinds of most wide pipeline corrosion protection modes at present is three-decker
Polyolefin erosion resistant coating and single layer powder epoxy.
(1) asphalt coating, the erosion resistant coating are to utilize glass fabric after pitch immersion treatment, are placed on defeated
The outer wall of oil-piping plays antisepsis.The technical matters comparative maturity, the prices of raw materials needed are cheap, at the same material and
The source of ingredient is easy, extensively.But the material heat-resisting quantity is lower, has high-hydroscopicity, due to having sucked more moisture, meeting
The antiseptic property of material is reduced, due also to the influence of the factors such as surrounding enviroment, will also result in the decline of anti-corrosion effect straight line.And labor
Dynamic condition is poor, and quality is difficult to ensure, environmental pollution is serious.
(2) epoxide coal bituminous, it is easy to operate, but coating curing time is long, and it is affected by environment big, it is unsuitable for field work
Industry, 10 DEG C or less are difficult to construct.
(3) clinkery epoxy powder corrosion-inhibiting coating, since clinkery epoxy powder corrosion-inhibiting coating is strong, resistance to steel tube surface cohesion
Chemical mediator erosion performance, heat resistance etc. are all relatively good, corrosion resistance, the fissility of resistance to cathode, resistance to ag(e)ing, the stress of resistance to soil
Etc. performances it is also fine, the wide of use temperature range but coating is relatively thin, anti-sharp object impact force is poor, easily by impact failure.
(4) epoxy powder anti-corrosion, using electrostatic spraying mode, good with same material corrosion-resistant tube body clinkering, bonding force is strong,
But epoxy powder waterproofness is poor, and (water absorption rate is higher, reaches 0.83%), certain difficulty is brought to cathodic Protection Design.Scene
Utensil requires height, and operation difficulty is big, and quality is not easy to control.
(5) polyolefin erosion resistant coating is divided to double-layer structure and two kinds of three-decker.The bottom of double-layer structure is adhesive, outer layer
For polyethylene;The bottom of three-decker is epoxy coating, and middle layer is adhesive, and surface layer is polyethylene.In three-decker
Epoxy coating can be liquid epoxy coating, be also possible to epoxide powder coating.
The major advantage of two-layer structure polyolefin erosion resistant coating is that insulation resistance is high, anti-stray current is good, easy for construction,
Major defect is that spiral shape overlapping the slot is long, easily coheres failure in lap-joint's generation and forms corrosive medium and penetrate into.
Layer polyethylene system erosion resistant coating, pipeline corrosion protection leakproofness is strong, and high mechanical strength, waterproofness is strong, and quality is stablized, and applies
Work is convenient, and applicability is good, free from environmental pollution.PE water absorption rate is low (being lower than 0.01%), is provided simultaneously with epoxy intensity height, PE water imbibition
Low and hot melt adhesive flexibility is good etc., there is very high anti-corrosion reliability, the disadvantage is that: cost height, complex process.
Currently, epoxy resin producing line is semi-automatic growth line both at home and abroad, production method is that horizontal life is horizontal, due to sky
Gas exists, and forms bubble or cavity in interlayer；The gravity generated due to terrestrial gravitation, the resin meeting of mold upper layer infiltration
Automatically it flows downward and causes upper layer resin few, to easily cause tubing upper and lower level wall thickness inconsistent, cause bias, so that
Tubing intensity is affected.
