2. Principle of experiment
Under the condition of defined temp. and washing time in the decontamination testing machine, the detergent solution with defined concentration is prepared by using water with a certain hardness, and various stain test pieces are washed, and the whiteness values of the test pieces before and after washing are measured by using whiteness meter under the selected wavelength.
3. Measurement of whiteness of stained cloth
Selecting a WSD-3 whiteness meter:
(1) preparing: placing the instrument in a well-ventilated room, checking a power line, and turning on a power switch;
(2) taking out the working white board and the blackboard from the instrument accessory box, and flatly placing the working white board and the blackboard on a laboratory bench;
(3) adjustment and correction
ZERO setting, namely, when a screen has ZERO, putting a blackboard on the sensor, and pressing a ZERO setting button;
correcting, namely putting a working white board on the sensor when the screen is in a 'STANDARD' state, and pressing a STANDARD button;
(4) measurement: after zero setting and correction, the measurement can be carried out, at the moment, the dirty cloth is placed on the sensor, two whiteness values are sequentially read, the cloth is turned over, the same operation is carried out, 2 readings are obtained again, 4 readings are measured for one piece of cloth, and the average value is the average whiteness value of the dirty cloth.
4. Hard water preparation and preparation of test solution
(1) Preparation of 2500mg/kg hard water
1.20g of anhydrous magnesium sulfate and 1.67g of anhydrous calcium chloride are accurately weighed, dissolved in a 1000mL volumetric flask, added with water to the scale and shaken uniformly.
(2) Preparation of test solution
Weighing 2g of laundry detergent into a 1000mL volumetric flask, adding 100mL of 2500mg/kg hard water, continuing adding deionized water to the scale, and shaking up.
5. Washing test
The washing test is carried out in a vertical decontamination tester, stirring impellers, a working groove and a decontamination bathtub are numbered and fixed one by one to form a 'working unit' before the measurement, the instrument is preheated to 30 +/-1 ℃ for a period of time, 1L of prepared test solution (preheated to 30 ℃ in advance) is poured into a corresponding decontamination bathtub during the test, the bathtub is placed in a corresponding position and the stirring impellers are installed, the temperature is adjusted to keep the experimental instrument at 30 +/-1 ℃, test pieces with whiteness measured are respectively placed into the bathtub, the stirring is started, the stirring speed is kept at 120r/min, the washing is stopped for 20min, the dirty cloth in the bottle is taken out and washed by tap water, and the dirty cloth is placed in an enamel disc for air drying and then the whiteness measurement is carried out (the method is the same as before).
6. Calculating the decontamination value and decontamination ratio:
stain removal value R ═ (∑ F)2-∑F1)/2
F2For whiteness after washing, F1Is the whiteness before washing. RTest forIs the sample laundry detergent detergency value, RStandard of meritIs the standard laundry detergent decontamination value.
The decontamination ratios of the three dirty cloth tests are all larger than 1, and the three dirty cloth tests meet the regulation of QB/T1224-.
7. The test results are shown in Table 3.
TABLE 3 detergency test results
And (4) analyzing results:
comparing groups a to e, it can be seen that the detergency of the active material composition in hard water is higher when the AES ratio AEO-9 is 3:1 to 5:1 (mass ratio), and particularly that the detergency of the active material composition in hard water is the strongest when the AES ratio AEO-9 is 4:1 (mass ratio).
Comparing group c and groups f to i, it can be seen that the detergency of the active material composition in hard water is higher when KY-CAO-30: CAB is 1:1 to 1:3 (mass ratio), and particularly that the detergency of the active material composition in hard water is the strongest when KY-CAO-30: CAB is 1:2 (mass ratio).
Comparing groups g and I-IV, it can be seen that the active compositions have the strongest detergency in hard water when the active compositions are composed of 7.5 parts by weight of component A and 1.5 parts by weight of component B.
As can be seen from the results of comparative group 1 and comparative group 2, the detergency in hard water is significantly lower than that of the other groups, indicating that the four components of AES, AEO-9, KY-CAO-30 and CAB can exert better hard water resistance and detergency.
