Abstract
The invention discloses a thermal shock resistance test method of a transparent glass piece of an explosion-proof lamp. The method includes the steps that (1) a transparent glass piece sample to be detected of the explosion-proof lamp is taken and placed in a thermostat, the temperature of the thermostat is regulated to be t1 which ranges from 110 DEG C to 290 DEG C, and after the transparent glass piece sample of the explosion-proof lamp is kept warm at the temperature of t1 for 1-6 hours, the transparent glass piece sample of the explosion-proof lamp is taken out; (2) test water with the temperature of t2 is provided, the t2 ranges from 20 DEG C to 35 DEG C, the thermal shock resistance of the taken out transparent glass piece sample of the explosion-proof lamp is detected with the test water, and whether the transparent glass piece sample of the explosion-proof lamp fractures or not is observed. If the transparent glass piece sample of the explosion-proof lamp does not fracture, it shows that the transparent glass piece sample of the explosion-proof lamp can endure the thermal shock temperature difference of delta t, wherein delta t=t1-t2. The test method is simple and convenient to operate and capable of being used for detecting the degree of the thermal shock resistance of the transparent glass piece of the explosion-proof lamp fast and effectively.
Description
Technical field
The present invention relates to a kind of heat resistanceheat resistant drastic change test method, relate in particular to a kind of explosion-proof lamp glass transparent spare heat resistanceheat resistant drastic change test method.
Background technology
Along with developing rapidly of industry, more and more important effect is played in illumination.Transparent Parts is light fixture indispensable matching component of when work, has protection, printing opacity, anti-dazzle effect.Because lamp power is large, the heating meeting of light source in the light fixture course of work is so that the rising of Transparent Parts temperature, rain or the abominable situation such as flushing light fixture if run into, the then unexpected drastic change of Transparent Parts surface temperature, if the heat resistanceheat resistant drastic change performance of Transparent Parts can not meet the demands, then can cause it to break, finally cause light source and electric component to damage, increase maintenance job and cost, even more serious situation is the Transparent Parts entail dangers to personal safety of breaking.
Heat resistanceheat resistant drastic change performance is to judge an important safety index of Transparent Parts quality.Traditional Transparent Parts heat resistanceheat resistant drastic change test method is that the Transparent Parts sample is contained on the light fixture, and under real use state, input rated voltage work is done popular drama change test to thermal equilibrium.The work because actual dress lamp is lit a lamp needs to change Transparent Parts at every turn, and can occur the damage of the parts such as light source, trigger, electric capacity, ballast resistor in the process of the test, has so not only increased laboratory technician's workload, has also increased experimentation cost.Therefore, have qualified heat resistanceheat resistant drastic change performance in order to guarantee the Transparent Parts product, a kind of energy is easy, and the test method that scientificlly and effectively detects Transparent Parts heat resistanceheat resistant drastic change performance quality becomes very necessary.
Summary of the invention
Embodiment of the invention technical matters to be solved is, a kind of explosion-proof lamp glass transparent spare heat resistanceheat resistant drastic change test method is provided, can be easy, and scientificlly and effectively detect the quality of explosion-proof lamp glass transparent spare heat resistanceheat resistant drastic change performance.
In order to solve the problems of the technologies described above, the embodiment of the invention provides a kind of explosion-proof lamp glass transparent spare heat resistanceheat resistant drastic change test method, may further comprise the steps:
(1) gets explosion-proof lamp glass transparent spare sample to be detected, be placed in the incubator, Temperature of Warm Case is adjusted to t
1, t
1Be 110 ℃～290 ℃, described explosion-proof lamp glass transparent spare sample is at t
1Insulation was taken out after 1～6 hour in the incubator of temperature;
(2) providing water temperature is t
2Test water, t
2Be 20 ℃～35 ℃, the described explosion-proof lamp glass transparent spare sample that takes out is detected its heat resistanceheat resistant drastic change performance with described test water, observing it has crack-free.
The purpose of step (1) be so that explosion-proof lamp glass transparent spare sample to be detected under the mal-condition of high temperature, integral body reaches thermal equilibrium state, is beneficial to subsequent detection.
Preferably, explosion-proof lamp glass transparent spare sample is at t
1Insulation was taken out after 4 hours in the incubator of temperature.Step (2) if in explosion-proof lamp glass transparent spare sample crack-free to be detected, show that then this explosion-proof lamp glass transparent spare sample can tolerate Δ t=t
1-t
2The popular drama temp .-differential.
The mode of the explosion-proof lamp glass transparent spare sample heat resistanceheat resistant drastic change performance of wherein, taking out with the test water detection in the step (2) is not limit.
Preferably, test water is contained in the glue case in the step (2), and the explosion-proof lamp glass transparent spare sample of taking-up directly immerses in the glue case of splendid attire test water.
Preferably, test water is contained in the container with nozzle in the step (2), the explosion-proof lamp glass transparent spare sample surfaces that test water is being taken out by nozzles spray.More preferably, the explosion-proof lamp glass transparent spare sample that takes out in the step (2) places on the iron grid, and the iron grid places on the hungry area case.
Reach the explosion-proof lamp glass transparent spare sample to be detected of thermal equilibrium state, the temperature value t under this state through step (1)
1Water temperature value t for the heat resistanceheat resistant drastic change temperature approach index of explosion-proof lamp glass transparent spare sample to be detected or prediction temperature approach and test water
2Sum, when it runs into suddenly the test water of low temperature, the drastic change of Transparent Parts sample generation instantaneous temperature.Because all objects all can produce the effect of expanding with heat and contract with cold, if moment difference variation excessive, for glass, will break, be fragmented into countless little glass blocks.
In addition, select the glue case as the test water container containing, in experimentation, will adopt a plurality of glue casees to be filled with water, prevent that test water from too much causing temperature to change along with placing sample size, and affect test result.
Employing detects the mode that test water directly sprays the explosion-proof lamp glass transparent spare sample surfaces of heating, and like this, sample interior does not pour water, more meets the actual operating position of light fixture Transparent Parts.
Implement the embodiment of the invention, have following beneficial effect:
(1) test method of the present invention is keeping under the constant condition of Transparent Parts failure mechanism, by using temperature difference test method, just can effectively judge the good and bad performance of Transparent Parts heat resistanceheat resistant drastic change, avoided the dress lamp to light a lamp, repeatedly change numerous and diverse program of Transparent Parts, thereby reduced testing expenses and experimenter's working strength;
(2) test method of the present invention is easy, easy to operate, can with detecting simultaneously with batch a plurality of samples, shorten the test period.
