Standard reagents for vertical stain removers with standard cloth

1、 Preparation of contaminated cloth test piece

1According to the standardsGB/T 13174-2021Requirements for detergent performance testing,Select the requiredJBSeries of test specimen varieties. Cut the contaminated cloth used for measurement into test pieces,Combine six groups with similar average chromaticity by category(To eliminate the differences between different batches of contaminated fabrics,Six sets of test pieces should use the same block as much as possibleJBSeries of dirty cloth cutting obtained). Used for stain removal testing in each groupJBEach type of test piece should4Film or more,Used for testing whiteness retention or cyclic washing performanceJB-00Each type of test piece should6piece,At the same time, keep a record of the numbering of the test pieces,Each set of test pieces is used for performance testing of one sample.

Note:

a:Each set of test pieces is used for performance testing of one sample,Determine the required number of test piece groups based on the quantity of measured products and the model of the cleaning machine,Six sets of test pieces are the maximum amount for one vehicle testing of common models of vertical cleaning machines.

b:In the determination of decontamination and washing,in accordance withJBDifferent varieties of test specimens in the series,Can test the cleaning power of detergents separately for different stains,Providing test results can also combine multiple types of stains to test their cleaning power together,Then compare and provide the test results separately. The test conditions should be specified in the test result report.

2According to the testing purpose,choiceJBSeries of dirty cloth,Measure the cleaning power or cyclic washing performance. Cut the dirty cloth into circular or square shapes of a certain size before use(for example,JB01/JB-02/JB-03For diameter6cmrotundity,JB-00for8cmX8cmsquare),Known as test piece, the uneven edges around each dirty cloth,The test piece can be cut off and needs to undergo multiple repeated washing tests to avoid a large amount of detachment during washing,If necessary, pre lock the edges with full cotton thread.

2、 Production of dirty cloth

Artificially dyed cotton fabric made by treating the original white cotton fabric with specified types of stains through a certain procedure,Used to measure the ability of detergents to remove such stains, determining the type of stain based on the type of stain.

JB-00The production

Cut cotton white cloth into rectangular pieces of a certain size along the warp and weft lines,Add to drum washing machine,Wash with tap water according to the standard washing mode of the washing machine,After shaking dry,Heat and wash with deionized water again30min,The washing temperature is60Around ℃,After being shaken dry, it is flattened and dried by an ironing machine or electric iron,Cut into a certain size(as27cmX44cm)That's it. For the next stage of preparing dirty cloth or testing the performance of cyclic washing.

JB-01Production of dirty cloth

Adjust the rolling pressure to0.3MPa.Adjust the sewage tank properly,Translate into EnglishJB-W1Used for contaminated liquid100mfabric filtration,Pour into the dirty liquid tank of the rolling mill.取JB-00After soaking and pressing the white cotton cloth once,Dip the stained cloth in the opposite direction again,Hang it to dry.

JB-02Production of dirty cloth

Weigh out6.7gGum acacia,After wetting with a small amount of water,Heat and dissolve on a water bath. put in4.5gcarbon black.Grinding about2minBackup use.

Weigh out38.6gmilk powder,join120mLAfter stirring the water evenly, add it to the above solution and mix it, and then add water to the total volume356ml.

Take a beaker and put it in70gegg liquid,Among them, egg white42g.egg yolk28g.356mlMix the water evenly and set aside for later use. Use an emulsifier to10000r/minHomogenize the solution at a speed of left and right,20minafter,Add egg mixture and continue to emulsifyd)40min,Make a dye solution.

Adjust the rolling pressure to0.3MPa,Adjust the sewage tank properly,Filter the prepared wastewater into the rolling mill wastewater tank using two layers of gauze.取1B-00White cotton fabric pad dyeing,Hang it to dry.
