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 utility model 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 utility model, 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.
