Embodiment
With reference to specific embodiment, the present invention is described in further detail, it is described be explanation of the invention and
It is not to limit.
One kind detection volatile method of optical cable, specific detecting step are：
Step (1)：Sample from finished cable needed for interception detection, per root long 300mm, quantity 5, ensure sample two
The port on side is smooth.
Step (2)：Sample mass before weighing detection with assay balance, comprises the following steps：
A, the quality of pan paper is weighed, is designated as m0；
Sample is placed on to the gross mass that sample and pan paper are weighed on pan paper, be designated as m b,1；
C, with sample and the gross mass m of pan paper1Subtract the quality m of pan paper0Draw the quality (m of sample1-m0)；
D, above-mentioned quality measurements and result of calculation retain after decimal point 4, and unit is gram.
Step (3)：Sample after weighing is lain in a horizontal plane in air -oven, oven temperature is 69 ± 1 DEG C.Inventor's phase
Hope and test process is accelerated by accelerated test, to be best understood from the volatility of optical cable.However, inventor is groping to accelerate examination
Found in the condition tested, the temperature of baking oven may not exceed 80 DEG C, and no person is in prolonged high-temperature baking, the material meeting in optical cable
Gradually softening, and then deform under gravity.Although still optical cable sample mass can be carried out under deformation condition
Measurement, still, inventor perceives, and the deformation in optical cable result in the change of cable interior structure, and this to volatilize in optical cable
The volatilization rule of property material has occurred that change, and measured volatility data can not reflect the volatilization of the optical cable of normal use
Property rule.Therefore, inventor is in order to enable detected optical cable volatility result more really to reflect that optical cable normally makes
The volatilization rule of used time, temperature is set at less than 80 DEG C.Meanwhile in order to further reduce high temperature to the material inside optical cable sample
The imperceptible destruction of material, inventor further reduce air -oven temperature to less than 70 DEG C.But when the temperature is low,
The acceleration effect of accelerated test is not notable, the test period length, therefore, after inventor is by balance, it is determined that baking oven optimal temperature
Spend for 68~70 DEG C.Moreover, it is optical cable sample is horizontal positioned, can reduce as far as possible optical cable experiment internal material by
Gravity influence, avoid the possible deformation of optical cable sample as far as possible, ensure detection result can more really reflect normal use
Optical cable volatility rule.
Step (4)：Sample is put into air -oven and starts timing, sample is loaded into test tube sealing after 12h, is cooled to room
Temperature, the quality of test sample.After being measured, the method as described in step 3), optical cable sample is put back in air -oven and continued
Heating.In this way, taking out sample measurement its quality at different time point, put back to after being measured in air -oven, until completing
Set time of measuring.In the present embodiment, the time interval measured every time is 12 hours, and the time of measuring set is 240
Hour.
The data obtained is used for step (5) or step (5A).Wherein, the data obtained uses following form of presentation：
mnFor the quality of the optical cable sample of n-th measurement gained；
mn+1For the quality of the optical cable sample of (n+1)th measurement gained
TnOptical cable sample is put into the time of air -oven for n-th measurement distance；
Tn+1Optical cable sample is put into the time of air -oven for (n+1)th measurement distance；
tn+1The time interval measured for (n+1)th measurement distance n-th, equal to Tn+1-Tn；
Step (5)：After test terminates, according to the mass loss of optical cable sample in different time sections, when being calculated different
Between optical cable rate of volatilization α, rate of volatilization α calculation formula is：
Wherein, mnFor the quality of the optical cable sample of last measurement gained；mn+1For the optical cable sample obtained by this measurement
Quality；tn+1For the time interval of this measurement distance last time measurement.Further, on the basis of the data of step (5), paint
Optical cable rate of volatilization α processed changes over time curve map.
Wherein, in the present embodiment, the time interval measured every time is fixed 12 hours, therefore depicts volatilization speed
Rate α is with pendulous frequency change curve.Wherein, time point corresponding to each measurement, pendulous frequency are multiplied by 12 hours.Gained is waved
Speed α is sent out to show in Fig. 1 with pendulous frequency change curve.
Obtain step 4) data after, can also without the method for step (5), and using the method for step (5A) come
Evaluate and test the volatility of optical cable.
Step (5A) draws period mass loss percentage βn+1With time of measuring point Tn+1Line chart, wherein,
In the present embodiment, the data of step (4) are handled using step (5A), acquired results drafting pattern 2.
Could be aware that according to Fig. 2, in the initial period of test, the extension over time of the volatility of optical cable and strengthen.The volatilization of optical cable
Property reached peak value at 100 hours or so, then gradually weaken；After 200 hours, the volatility of optical cable, which tends towards stability, (volatilizees
Degree tends to constant value), therefore, when assessing the volatility of optical cable according to method provided by the invention, test period needs to reach 200
It was optimal with 240~300 hours more than hour；Further extend test period to be difficult to obtain more valuable test data.
