Description

A kind of oil volatility measurement device
Technical field
The present invention relates to oil product volatility sensing equipment technical field, the oil volatility measurement device that particularly a kind of measurement result error is little.
Background technology
Oil product is in use because the speed of evaporation rate can produce series of problems, such as: have some oil products to volatilize than very fast and pollute or lose effectiveness, but oil film rapidly dry (or how long oil film " exsiccation ") can be required other some use occasions user, in this case the evaporation rate of oil product is then required to want fast and can not be too slow, in addition, under different environmental baselines, at (as ventilated from stuffy), different temperature, oil product rate of volatilization also can be different.As can be seen here, can know that the volatility of certain oil product is concerning very important user definitely, and the rate of volatilization of oil product also do not have method of testing and the related experiment instrument of standard at present.A kind of method of the prior art is: be laid in foil disk by a certain amount of petroleum product samples to be measured, insert in the Constant Temp. Oven of steady temperature, start stopwatch immediately, after the stipulated time, take out sample put into exsiccator, weigh with analytical balance after cooling in 10 minutes and calculate the variable quantity putting into oil product before and after baking oven at the appointed time, calculating the data such as the rate of volatilization of oil product, oil product residue thus.But this measuring method of the prior art has following shortcoming:
1) operation is inconvenient, error link is more, traces it to its cause and is:
A, in Constant Temp. Oven, because wind speed is uncertain and uneven, the evaporation rate of oil product is made to produce difference;
B, take out from drying box come analytical balance to carry out in the process weighed may with some materials in air at high temperature time react or adsorb aqueous vapor, dust and so on material and cause error;
C, the evaporating dish after just heating is placed into sample in the process of room temperature and continues some composition in volatilization or air and may to adhere on sample thus to produce error;
The putting into and take out the operational time difference and manual time-keeping also can produce error of d, sample;
2) result that the method is measured is only example weight changing value at the appointed time, namely the result that measured value calculates is the average volatility of oil product in this period, in fact, oil film is not constant value at not rate of volatilization in the same time, weight/the time curve of actual measurement oil film is not straight line, and namely the volatility of Different periods is unequal.Therefore, the method for the average volatility of this employing of prior art a certain period science can not reflect the volatile performance of oil product exactly.
As can be seen here, how to work out a kind of oil volatility measurement device, the oil product volatility result that records can be made closer to the volatility of oil product reality, and for user selects different oil products to provide reference accurately and effectively according to its demand, this is the current technical issues that need to address in this area.
