Experimental example 1: cleaning effect test

3 Pieces of 20 x 20cm tinplate were prepared for testing, with a soil of 12g of N68 engine oil + 2g of carbon black.

The testing steps are as follows:

Weighing the mass m1 of the iron sheet.

Marking a circle with the diameter of 12cm on the iron sheet, uniformly coating dirt in the circle with the dosage of 0.20 g-0.25 g, and weighing the mass m2 of the dirt-coated iron sheet.

Fixing the dirt-coated iron sheet on a vertical horizontal object, filling a sample into a hand spray bottle, spraying for 4-6 times 15 cm-20 cm away from the dirt iron sheet, wiping dirt for about 20 times by using dry clean soft cloth after waiting for 4-6 s, repeatedly cleaning the iron sheet for 3 times according to the operation, and weighing the mass m3 of the iron sheet after wiping.

The data of the test of example 1-example 3 were recorded, and the cleaning effect of the cleaning agent was tested with the data of the comparative example as a control. The measurement results were calculated according to the following formula:

X＝(m2-m3)/(m2-m1)*100％，

Wherein:

x—decontamination rate in percent (%);

m 1A test piece mass before dirt application, in grams (g)

M2 is the mass of the test piece after dirt is smeared, and the unit is gram (g);

m 3A test piece was wiped and its mass was measured in grams (g).

According to the calculation results, the greasy dirt removal rate of the cleaning agents prepared in examples 1-3 reaches over 92%, and the cleaning agent prepared in comparative examples still has greasy dirt removal capability, but the effect is obviously inferior to that of the cleaning agents prepared in examples 1-3, as shown in Table 1.

Table 1 cleaning effects of the cleaning agent

Experimental example 2: flash point test

The test was performed at a location that was wind-tight and dark.

According to the test results, the flash points of the cleaning agents prepared in the examples 1-3 are between 180 ℃ and 186 ℃ and are shown in Table 2 in detail.
