Appearance

Milky white liquid

Inspection Method: Observe the color of the liquid visually.

Solid Content

60%

Inspection  Tools: Watch glass (with a diameter of 7.5cm), oven, high-precision electronic scale.

Inspection Method: Stir the test liquid evenly, take a sample of 2.0g ± 0.5g in a surface dish that has been weighed, weigh it, gently rotate the surface dish, and cover the bottom of the surface dish with the sample. Put it in an 80℃ oven for about 2 hours, weigh it multiple times during heating, make the difference between the two weighings less than 0.005g, and obtain the weight of the solid. Conduct 2 parallel experiments and take the average value.

PH

7~9

Inspection  Tools: Electronic PH Meter.

Inspection Method: Use an electronic pH meter that has been calibrated in a calibration solution to measure the sample taken out.

Viscosity

1200-1400cP

Inspection  Tools: Brookfield viscometer,5# rotor.

Inspection Method: Put the sample into a large caliber beaker or bottle, select the 5# rotor for installation and debugging, immerse the rotor in the sample until the mark, select the speed of 100RPM, and measure the viscosity value.

Adhesive force

Good

Inspection Method: Cut out a small piece of carpet, smooth the carpet, apply the glue evenly on the back of the carpet according to the glue amount of 2.0-2.4kg/m3, and put it in the oven to dry. Pull the dried carpet by hand to see if any fur will fall off.
