Foreword
This standard while lieu consolidated GB/T 16497-1996 "surfactant-oil-water emulsion stability Part 1 Test Method
Score. water in oil emulsion storage stability was measured oven method "and GB/T 16498-1996" water emulsion stability of surfactant-oil
Test methods - Part 2. Determination of storage stability of water in oil emulsion - Low to ambient temperature cycling method. "
This standard and GB/T 16497-1996 and GB/T 16498-1996 compared, the main differences are as follows.
--- Name specification standard "measurement water emulsion storage stability of the surfactant-oil."

Determination of water in oil emulsion storage stability
1 Scope
This standard specifies the surfactant-oil emulsion at different temperature changes, emulsion stability measurement method.
This standard applies to the surfactant-oil emulsion at a constant temperature, and raised to 21 ℃ ± 3 ℃ to -18 ℃ ± at room temperature
1.5 ℃ room temperature cycling, its use and determination of storage stability.
2 Normative references
The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, all subsequent
Amendments (not including errata content) or revisions do not apply to this standard, however, whether under this standard to encourage the parties to reach an agreement and research
You can use the latest versions of these documents. For undated reference documents, the latest versions apply to this standard.
Determination of GB/T 11275-2007 surfactant water content
3 Sampling
In order to ensure uniformity of the sample, pipetting the required amount in the previous test, the sample must be thoroughly mixed. 1L or less capacity for 1L
, You can manually vigorous agitation or mechanical mixing 3min ~ 5min. For larger containers, stirring time may be extended to
Ensure sample homogeneity.
4 instruments and equipment
4.1 thermostatic oven, temperature fluctuation range is less than equal to the difference between the oven temperature and the room temperature of ± 1%;
4.2 graduated cylinder, 100mL stoppered glass cylinder, sub-scale of 1mL, cork with venting slots;
4.3 pipettes, 10mL;
4.4 bottles, about 30mL;
4.5 Refrigerator. Can temperature control in the refrigerator or freezer of -18 ℃ ± 1.5 ℃.
5 measurement method
5.1 oven method
Method summary. The 100mL samples were transferred to a graduated cylinder, the cylinder placed in 85 ℃ constant temperature oven with a blast of 48h or 96h, and then
Determination of the amount of sample is separated from oil and water. Further, the upper and lower samples specified moisture content level may be obtained separately.
5.1.1 Method A. 48h Test
5.1.1.1 48h test procedure
The 100mL samples were transferred to a graduated cylinder, covered with cork. The cylinder is placed in a thermostat at 85 ℃ ± 1 ℃ constant temperature oven 48h. the amount
Tube placed in the middle of the oven, from the bottom of the oven at least 75mm, in order to ensure temperature uniformity.
The cylinder is removed from the oven and allowed to stand at room temperature for 1h, observe and record the volume of separating oil and water. And the pipette tip accurate
Graduated cylinder placed at 80mL, 10mL sample was slowly pipetted into glass vials, as an upper layer sample; then placed accurately pipette tips
15mL graduated cylinder at the slow shift of 10mL sample into a glass bottle, as a lower layer sample.
Note 1. When several simultaneous determination of the cylinder should be placed to avoid the lack of convection caused by the temperature difference between the oven. And determining the number of samples should be
limit.
Note 2. If the amount of water separation equals or exceeds 10% in volume, the lower the moisture content of the sample was selected to do the steps.
