Description
Technical Field
The utility model relates to a resin production technical field specifically is a resin material production line based on vertical heavy vertical stretching method.
Background
As is well known, a product made of glass fiber reinforced epoxy resin (or unsaturated polyester) is also called epoxy resin pipe, and is widely used in national defense, industrial and agricultural production and daily life of people, such as missile shell and satellite fairing, heat-proof material of spacecraft, shells, fins and propellers of aircrafts and ships, etc., the glass fiber reinforced epoxy resin (or unsaturated polyester) product is mainly used for pressure vessels and pipelines, anticorrosion vessels, automobile instrument panels, bumpers, electrical insulation members, yachts, etc. in civil industry, when the glass fiber reinforced epoxy resin (or unsaturated polyester) product is mainly used for various pipelines, the production process mainly comprises coating epoxy resin (or unsaturated polyester) on glass fiber, winding the glass fiber coated with epoxy resin (or unsaturated polyester) layer by layer through compression rollers and winding shafts, after the winding thickness reaches the requirement of the pipe wall, a glass fiber reinforced epoxy resin (or unsaturated polyester) blank pipe is produced, and then high-temperature curing is carried out, so that the final finished pipe can be obtained. However, in the production process, the most common problem is that in the winding process, due to the existence of air, bubbles or cavities are formed between layers, which seriously affects the quality and performance of the product, and causes low product yield and increased production cost. And the glass fiber is away from the winding roller by a certain distance after the sizing step, the phenomenon of glue solution agglutination often occurs in the distance conveying process, so that the glue solution is unevenly distributed in the later-wound overshoot, and tiny air chambers can occur in the pipe wall after the drying treatment, which seriously affect the product quality and the service life of the finished pipe
Another common drawing and squeezing process is to soak felt, cloth, continuous untwisted yarn and other reinforcing material in resin, to produce pipe with unlimited length, and to draw the pipe with a tractor.
The mechanical strength of the epoxy resin is mainly determined by the fibers, and the main function of the matrix resin is to bond the fibers together and transmit stress strain. If the bonding between the resin and the fibers is poor, stress cannot be effectively transmitted between the fibers, and it is difficult to exert the main load bearing effect of the fibers.
The following examples of the application of epoxy resin in insulating towers and petrochemical pipelines are as follows:
firstly, insulating pole tower:
in recent years, due to the expansion of the application field of glass fiber composite materials, the glass fiber composite materials have excellent characteristics of light weight, high strength, weather aging resistance, strong corrosion resistance and the like, and are used in products such as power transmission poles, towers and the like in the field of power communication and power transmission, so that the insulation property of lines can be greatly improved, and the pollution flashover resistance, ice flashover resistance, windage yaw resistance and lightning resistance of the lines can be greatly improved. The performance and use of composite transmission towers has been gradually valued in the power field.
Most of the existing towers designed by composite materials are single-pole type towers, and the transmission voltage class of the towers is limited below 35 KV. The higher voltage level can not be applied, and the bearing capacity can not meet the special requirement of the high voltage level, so that the development of the composite material tower is limited.
Secondly, petrochemical engineering pipelines:
the steel pipeline anticorrosive coatings which are widely applied in China comprise petroleum asphalt, PE jackets and PE foam jackets, epoxy coal asphalt, coal tar enamel, epoxy powder, a three-layer composite structure and the like, and two pipeline anticorrosive modes which are most widely popularized and applied at present are a three-layer structure polyolefin anticorrosive coating and single-layer powder epoxy.
(1) The petroleum asphalt anticorrosive coating is prepared by soaking glass fiber cloth in asphalt and is placed on the outer wall of an oil pipeline to play a role in corrosion prevention. The technology is mature, the needed raw materials are low in price, and the sources of the materials and the ingredients are easy and wide. However, the material has low high temperature resistance and high water absorption, and the corrosion resistance of the material is reduced due to the absorption of a large amount of water, and the corrosion resistance effect is also reduced linearly due to the influence of factors such as the surrounding environment. Moreover, the labor condition is poor, the quality is difficult to ensure, and the environmental pollution is serious.
(2) The epoxy coal tar pitch has simple and convenient operation, but the covering layer has long curing time, is greatly influenced by the environment, is not suitable for field operation and is difficult to construct at the temperature of below 10 ℃.
(3) The fusion bonded epoxy powder anticorrosive coating has strong adhesion force with the surface of a steel pipe, good chemical medium corrosion resistance, good temperature resistance and the like, good corrosion resistance, cathode stripping resistance, aging resistance, soil stress resistance and the like, and wide use temperature range.
(4) The epoxy powder is anticorrosive, and is well sintered with a pipe body which is made of the same material and is anticorrosive by adopting an electrostatic spraying mode, the bonding force is strong, but the waterproofness of the epoxy powder is poor (the water absorption rate is higher and reaches 0.83 percent), and certain difficulty is brought to the design of cathode protection. The requirements of field appliances are high, the operation difficulty is high, and the quality is not easy to control.
(5) The polyolefin anticorrosive layer has two structures, namely a two-layer structure and a three-layer structure. The bottom layer of the two-layer structure is adhesive, the outer layer is polyethylene, the bottom layer of the three-layer structure is epoxy coating, the middle layer is adhesive, and the surface layer is polyethylene. The epoxy coating in the three-layer structure can be liquid epoxy coating or epoxy powder coating.
The polyolefin anticorrosive layer with the two-layer structure has the main advantages of high insulation resistance, good stray current resistance and convenient construction, and has the main defects of long spiral lap joint and easy adhesion failure at the lap joint to form corrosive medium infiltration.
The polyolefin anticorrosive coating with the three-layer structure has the advantages of strong pipeline anticorrosion and sealing performance, high mechanical strength, strong waterproofness, stable quality, convenience in construction, good applicability and no environmental pollution. The PE has low water absorption (lower than 0.01 percent), high epoxy strength, low PE water absorption, good hot melt adhesive flexibility and the like, has high anticorrosion reliability and has the following defects: high cost and complex process.
At present, epoxy resin production lines at home and abroad are semi-automatic growth lines, the production mode is horizontal, and bubbles or cavities are formed between layers due to the existence of air; due to gravity generated by the gravity, resin soaked in the upper layer of the mould can automatically flow downwards to cause less resin in the upper layer, so that the wall thickness of the upper layer and the wall thickness of the lower layer of the pipe are not consistent, eccentricity is caused, and the strength of the pipe is influenced.
