This ageing oven being applicable to tubulose sample can be used in process plastic conduit and plastics gas cylinder sample, this ageing oven being applicable to tubulose sample can meet the accelerated aging test of GB/T14522-2008 and GB/T16422.1-2006 standard in the lab to non-metal tubular sample by the high-energy accelerated deterioration ray source of the standards such as ultraviolet, xenon lamp, carbon arc lamp, namely aging light source 8 is ultraviolet or xenon lamp or carbon arc lamp, and aging light source 8 is fixed in this casing 10 being applicable to the ageing oven of tubulose sample by light source fixture 9.This ageing oven being applicable to tubulose sample by the irradiation to tubulose sample 3, for further performance test provides sample after the accelerated deterioration of surface uniform.
Specimen holder 2 can drive the tubulose sample 3 handled by this ageing oven to move to close or away from aging light source 8 direction.The below of specimen holder 2 is provided with sample slide rail 1, sample slide rail 1 along aging light source 8 and this ageing oven the line direction of treatable tubulose sample 3 axis arrange.
Specimen holder 2 comprises the rotating disk for fixing tubulose sample 3, and the axis of this rotating disk and the dead in line of tubulose sample 3, specimen holder 2 also comprises the motor that this rotating disk can be driven to rotate for axle with the axis of this rotating disk.Specimen holder 2 is connected with sample control system, by sample control system Control Assay fixture 2, thus tubulose sample 3 is rotated and moves along close or away from aging light source 8 direction.Simultaneously, this sample control system is by this motor of control and rotating disk thus given pace rotation pressed by control tubulose sample 3, even to ensure the photoreceiving surface of tubulose sample 3, the velocity of rotation of tubulose sample 3 needs to control within limits, both ensured the homogeneity of specimen surface ageing process, and can ensure again not bring effects of reduced temperature because rotating speed is too fast to tubulose specimen surface.Concrete, specimen holder 2 can comprise top rotary table and the lower rotary table of stacked setting, the center of lower rotary table is provided with convex axle, this convex axle is plugged in top rotary table, and motor can drive top rotary table with this convex axle for axle rotates, and top rotary table can fix tubulose sample 3, the axis of this convex axle and the dead in line of tubulose sample 3, lower rotary table is provided with the chute matched with sample slide rail 1, and lower rotary table can move along sample slide rail 1, thus drives top rotary table to slide along sample slide rail 1 together with tubulose sample 3.
The described ageing oven being applicable to tubulose sample also comprises light intensity probe 6, and light intensity probe 6 is positioned at the top of the treatable tubulose sample 3 of this ageing oven institute, simultaneously light intensity pop one's head in 6 be also positioned at this ageing oven the concordant position of the outward flange of treatable tubulose sample 3.Light intensity probe 6 is for detecting the irradiation intensity that tubulose sample 3 outside surface is subject to.Light intensity probe 6 is connected with probe slide rail 4 by probe gripper 5, and light intensity probe 6 and probe gripper 5 can move back and forth along probe slide rail 4, this probe slide rail 3 along this aging light source 8 and this ageing oven the line direction of treatable tubulose sample 3 axis arrange.Probe gripper 5 and probe slide rail 6 are existing device or structure, no longer specifically introduce.
Light intensity probe 6 is all connected with intensity control system with aging light source 8, and this intensity control system can be popped one's head according to light intensity, and to realize the irradiance that tubulose sample 3 receives constant for supply current that the 6 actual irradiation intensities received adjust aging light source 8 automatically.The effect of intensity control system is when tubulose sample 3 is away from aging light source 8, can cause the variable density of light source.Now receive actual irradiation intensity for foundation with light intensity probe 6, supply current is turned or tuned up to system down automatically to realize the constant of irradiance.The actual irradiation intensity that such as light intensity probe 6 receives is greater than preset value, then intensity control system is by reducing the electric current of aging light source 8, to reduce the irradiance that tubulose sample 3 receives; If the actual irradiation intensities that receive of light intensity probe 6 are less than preset value, then intensity control system is by increasing the electric current of aging light source 8, and to improve the irradiance that tubulose sample 3 receives, thus it is constant to realize the irradiance that tubulose sample 3 receives.
Two shading baffles 7 are positioned at same plane, this plane orthogonal in tubulose sample 3 to aging light source 8 near or away from direction.Two shading baffles 7 can close to each other or away from.Two objects every baffle plate 7 are set and are width by controlling described crack thus the width controlling the ray that aging light source 8 gives off, reduce the operation of ray to ensure that tubulose specimen surface connects irradiated place and remains within angle θ.The minimum intensity of light E of the edge accepted in irradiation range need be made

Shading baffle 7 is for splitting packaged type, and its objective is that the light after according to the change in radius of adjustment tubulose sample 2 exposes width, the angle making specimen surface receive the multipair central angle of answering in region of irradiation remains within the scope of θ °.The permission light pass of exposing between width d and θ and r that shading baffle 7 adjusts is d=2r × sin θ/2, requires that centrally line is symmetrical.
Distance between aging light source 8 and tubulose sample 3 is controlled by mobile tubulose sample 3 and specimen holder 2 on sample slide rail 1, and it must be made to remain certain certain value d, and (d need meet: both ensured not because of too small apart from radiation intensity too far away; Again can not because of light source and sample excessively close to and affect the homogeneity of specimen surface irradiation intensity, and the effect of the aging light source of variable effect because of specimen surface, concrete range data can with reference to the design of the international ripe company such as ATALAS, Q-LAB), if d can be 50mm.
The described ageing oven being applicable to tubulose sample comprises for realizing the constant intensity control system of irradiance that tubulose sample 3 receives, also comprises the sample control system for controlling tubulose sample 3 velocity of rotation.The equipment such as the described ageing oven being applicable to tubulose sample also comprises temperature control, control is wet are as all identical with the ageing oven of ordinary flat sample in blackboard temperature meter, firing equipment, sprinkling equipment, cooling device etc., introduce no longer in detail at this patent.
The above; be only specific embodiment of the utility model, the scope of utility model enforcement can not be limited with it, so the displacement of its equivalent assemblies; or the equivalent variations to do according to the utility model scope of patent protection and modification, all still should belong to the category that this patent is contained.In addition, the technical characteristic in the utility model and all can using by independent assortment between technical characteristic, between technical characteristic and technical scheme, between technical scheme and technical scheme.
