3 Sample Preparation

The sample (if necessary warm) with a stainless steel stirring rod, stir, to reap 500g, stir for testing.

4 Appearance Test

4.1 instruments and equipment 4.1.1 colorimetric tube. 25mL. 4.1.2 constant temperature water bath. 4.1.3 glass rod. φ10mm. 4.2 Test Procedure 4.2.1 take emulsifier 20mL, into a colorimetric tube, placed in a water bath at 50 ℃ ± 5 ℃ in the warm 10min. Remove and wipe away the colorimetric tube water. Against the natural light visually observe and record observable phenomena. 4.2.2 The glass rod is inserted below the liquid level emulsifier 5cm, brought to the surface of the glass rod over 0.4m, so emulsifier flow freely. Visually Observation of flow conditions, record observable phenomena. 4.3 Expression of results Samples reported observations (whether uniform and transparent, without suspended particles and foreign matter, whether thin strip was uniform when the shed). ......
