However, the above methods are not suitable for the determination of the UV stability of light-colored petroleum products such as rubber filler oil, 150BS bright oil, and white oil. For the UV stability of petroleum products, it is necessary to establish a method suitable for the determination of the UV stability of these light-colored petroleum products

Embodiment 1-5

[0008] Take 5 samples including KN4006, 15# white oil, K4010 (6-1), 150BS bright oil (7-1), and Qingrun (8-1) for the test. Take 120ml samples respectively, pour them into clean and dry test cups, place them symmetrically on the position of the test cups on the turntable of the test chamber, turn on the high-pressure mercury lamp, turn on the ventilation fan, and adjust the temperature in the chamber to 40-60°C. When the temperature reaches the specified temperature, start to count the time and keep the constant temperature during the test. After 1×(1±0.5)h, turn off the power of the instrument, open the door, take out the test cup and put it in the desiccator. According to the requirements of the customer Use GB / T3555 or GB / T6540 or SH / T0168 for color evaluation. Pour the measured sample into the original test cup, and then place it on the position of the original test cup on the turntable of the test box, follow the measurement steps of the first hour, and carry out the meas...

Abstract

This invention relates to an analysis method for ultraviolet light stabilization of petroleum product and is characterized by the following: the ultraviolet light power is 375W; its shooting time is one to six hours; its temperature is 40 to 60 deg. C; its ultraviolet wavelength is 365 nm. The sample after being shined may choose GB / T3555 or GB / T6540 or SH / T0168 to evaluate its color. This invention is of high utility and its adopted operation conditions is close to those of light-color petroleum products and its manufactured products and so the measured results of this invention can satisfy the needs of ultraviolet light stabilization of petroleum product. This operation is simple without any difficult technical demands in the process and can get accurate result only if it can correctly judge the colors.

Description

Technical field: [0001] The invention relates to a method for analyzing the ultraviolet light stability of petroleum products. Background technique: [0002] At present, the only petrochemical industry in my country for the determination of the UV stability of paraffin is SH / T0404. This method is only applicable to the determination of the light stability of refined paraffins. The measurement conditions are: UV lamp power: 375W, irradiation temperature: 90±2°C, irradiation time: 60min, ultraviolet wavelength: 365nm, and the chromaticity measurement method after irradiation is: SH / T0403 (paraffin wax colorimetric method). It cannot be used for the determination of the UV stability of liquid petroleum products, so this method has certain limitations. In addition, in China, Yueyang Petrochemical Rubber Factory has built a method for evaluating the light stability of oil-extended SBS rubber, that is, using a 15W ultraviolet lamp to measure oil-extended SBS rubber, and the samp...
