Description
Technical field
The present invention relates to a kind of processing unit (plant) of fibrous composite, especially a kind of preparation facilities of civil engineering FRP muscle.
Background technology
Reinforcing bar, as a kind of important construction material, is widely used in Structural Engineering.But a large amount of engineering practices shows, change the use of cryosel, harsh climate condition and other factors and easily cause reinforcing bar and steel strand wires corrosion, durability declines to cause xoncrete structure to occur.Fiber-reinforced polymer (Fiber Reinforced Polymer, being called for short FRP) muscle has the advantages such as high-strength light, corrosion-resistant, underrelaxation and anti-fatigue performance are good, using FRP muscle as vertical muscle, abdomen muscle or presstressed reinforcing steel be used in xoncrete structure, the durability of xoncrete structure can be improved, there is good economic and social benefit.
FRP muscle is made up of with the polymeric matrix two parts with cementation the fiber with drawing-resistant function.Wherein, adopt the FRP muscle of thermosetting resin matrix due to features such as its production equipment are simple, energy consumption is low, be progressively widely applied in civil engineering.The traditional processing technology adopting the FRP muscle of thermosetting resin matrix mainly to adopt pultrusion to be wound around, comprise send yarn, impregnation, shaping, be wound in the process such as rib and heat hardening.Traditional FRP muscle preparation facilities comprises creel, steeping vat, threading board, mould, roll, heat tunnel, hauling machine and the cutting machine that the direction of transfer along FRP muscle sets gradually.But, in the FRP muscle product adopting traditional FRP muscle preparation facilities to produce, part FRP muscle tensile strength is low, and standard deviation is larger, the design of restriction FRP muscle in xoncrete structure and application, simultaneously in the process of producing, in heat tunnel, often easily pile up a large amount of thermosetting resins, affect normally carrying out of FRP muscle production.
In order to solve above Problems existing, people are seeking a kind of desirable technical solution always.
Summary of the invention
Technical staff is through large quantitative analysis, recognize and cause part FRP muscle tensile property deficiency, one of reason that tensile strength standard deviation is larger is the on the low side and skewness of the fiber content in product, a large amount of research and experiment shows, the origin cause of formation of this phenomenon is caused to be: the thermosetting resin mobility in steeping vat is lower and along with the growth of production time, mobility constantly reduces, make thermosetting resin that fibre bundle wraps up too much and degree of steeping is different, thus cause in finished product occur fiber content reduce and problem pockety, simultaneously, after entering heat tunnel, the mobility of thermosetting resin increases fast, before heat cure, lower of a large amount of thermosetting resin, be deposited in heat tunnel, affect the distribution normally carried out with fiber in FRP muscle and matrix that FRP muscle is produced.Therefore, the mobility of the thermosetting resin ensured in steeping vat remains on higher level and keeps constant is the key of dealing with problems.
The object of the invention is for the deficiencies in the prior art, provide a kind of steeping vat, the present invention simultaneously also provides the FRP muscle preparation facilities with this steeping vat.
To achieve these goals, the technical solution adopted in the present invention is: steeping vat, comprise for holding the impregnation cell body of thermosetting resin matrix and the constant temperature heating device for heating impregnation cell body, described impregnation cell body is located in described constant temperature heating device.
Preferably, described constant temperature heating device comprises water tank and heating control system, the electric heater that described heating control system comprises controller, is located at the temperature sensor in described water tank and is located in described water tank, described controller is connected with described temperature sensor sampling, described controller and described electric heater control connection.
Preferably, the described water tank heat-insulation layer that comprises skin, internal layer and be located between inside and outside layer.
Preferably, described heat-insulation layer is asbestos layer or vacuum layer.
Steeping vat hinge structure of the present invention has substantive distinguishing features and progress, specifically, pass through constant temperature heating device, impregnation cell body is heated, thermosetting resin keeps constant temperature in impregnation cell body, thermosetting resin is made to keep good mobility for a long time at a proper temperature, make fibre bundle impregnation abundant, evenly and kiss-coating is less, improve the fiber content of FRP muscle, the uniformity coefficient of fiber and resin distribution and the curing rate with thermosetting resin matrix, reduce the stackeding speed of thermosetting resin in heat tunnel, solve the problem that FRP muscle tensile strength standard deviation is bigger than normal, improve the Performance and quality of FRP muscle.
Further, adopt heating water bath, constant temperature heating device structure is simple, and cost is low and effective.Heating control system can Real-Time Monitoring water temperature, and occurs that change Time Controller is intervened in time by controlling electric heater in water temperature, and automaticity is high, easy to use.
Further, the heat-insulation layer between the inside and outside layer of water tank, can reduce heat loss, economize energy.
FRP muscle preparation facilities, this FRP muscle preparation facilities has the steeping vat of said structure.
Preferably, the heat tunnel of this FRP muscle preparation facilities comprises the low-temperature setting passage, hot setting passage and the shaping drying channel that set gradually along FRP muscle direction of transfer.
FRP muscle preparation facilities of the present invention, owing to having the steeping vat of said structure, therefore, the pull resistance solving part FRP muscle in prior art is poor, the problem that FRP muscle performance standard difference is bigger than normal, and concrete effect foregoing describes, and does not repeat them here.
Further, the heat tunnel of this FRP muscle preparation facilities comprises the low-temperature setting passage, hot setting passage and the shaping drying channel that set gradually along FRP muscle direction of transfer, because thermosetting resin matrix solidifies slowly in low-temperature setting passage, the comparison in difference of the inside and outside solidification of thermosetting resin matrix is little, reinforcedathermoset matrices through to a certain degree solidifying enters in hot setting passage and carries out rapid curing, then dry in shaping drying channel, this curing mode improves the uniformity coefficient of solidification, further increases the performance of the Performance and quality of FRP.
