The cleaning effect of the pipeline cleaning agent prepared in the embodiments 1 to 3 of the invention is systematically evaluated by a degreasing capability test by taking a commercially available pipeline cleaning agent as a reference.

Degreasing ability test

(1) Material preparation

a. Cleaning agent for pipelines: tap water was used to prepare a 1:100 concentration sample solution.

b. Artificial dirt (mixed oil): mixing the following raw materials in butter: lard oil: the vegetable oil is prepared according to the proportion of 1:1:2, and the polyglycerol ester fatty acid accounting for 5 percent of the total mass of the vegetable oil is added to obtain the mixed artificial oil stain, and the mixed artificial oil stain is cooled at the temperature of minus 5 +/-0.5 ℃ for standby.

c. Preparing an oil stain slide glass: and boiling the glass slide in deionized water for 15min, wiping, then soaking in an acid washing solution for 1h, washing with clear water until no acid liquor is left on the glass slide, and then washing with the deionized water. And (4) drying, namely drawing a line from top to bottom of the glass slide by 10mm, and limiting oil stains below the line for later use.

(2) Smearing method

The pretreated slides were weighed precisely (to 0.001g) using an analytical balance and recorded as m₀After the weighed slide glass is fixed by a clamp along a line of more than 10mm, smearing is prepared.

When the oil stain is kept at a certain temperature (when the room temperature is 20 +/-0.5 ℃, the oil temperature needs to be heated to 80 ℃, when the room temperature is 25 +/-0.5 ℃, the oil temperature needs to be heated to 45 ℃, when the room temperature is too high or too low, the test is not suitable, and the room temperature needs to be adjusted to a proper temperature range), the clamp for fixing the slide glass is held by a hand, the slide glass is immersed into the oil stain for 1-2 s below a line of 10mm, and the slide glass is slowly taken out. After standing at room temperature for 4h, the mixture is weighed (to the nearest 0.001g) using an analytical balance and recorded as m₁At this time, the amount of smears on the smeared sheet was 0.5. + -. 0.05 g.

(3) And (3) determination of decontamination rate: taking a proper amount of pipeline cleaning agent to prepare a sample solution with a corresponding concentration, heating the sample solution in a water bath at 30 ℃ while stirring until the mixture is uniformly stirred and the temperature rises to 30 ℃. And fixing the slide glass together with the clamp above the sample solution, and ensuring that the part below a line of 10mm on the slide glass is immersed in the sample solution for 1 min. After the slide is fixed, the magnetic stirring is started, the set rotating speed is 150r/min, and the duration is 5 min. After the end, the slide glass and the clamp are taken out and put back to the original position, the slide glass is dried for 3 hours at room temperature until the slide glass is completely dried, and the slide glass is weighed to be m by an analytical balance₂(accurate to 0.001 g).
