2 results and discussion
The performance test of 2.1AAA, BBB
2.1.1 alkalinity
The AAA of the configuration different quality concentration working solution of scouringing and bleaching, measures its pH value and calculates alkali content, the results are shown in Table 2.
Table 2 variable concentrations AAA scouring and bleaching pH value and the alkalinity of liquid
As can be seen from Table 2, low temperature scouring and bleaching agent AAA alkalinity lower be 26.63%.It is 10.5 left and right that the working solution pH value of COTTON FABRIC hydrogen peroxide bleaching requires, and AAA mass concentration pH value in the time of 3g/L is 10.7, the requirement of best pH value 10.5-10.8 when composite oxygen is floated.Therefore, in general technology formula, need to add the 3g/L low temperature agent AAA that scourings and bleaching can meet technological requirement.
2.1.2 permeability
Prepare respectively the common refining agent FRD-88 of 1～6g/L and low-temperature refining agent BBB working solution, test the permeability of the two, the results are shown in Table 3.
Permeability/the s of the different refining agents of table 3
As can be seen from Table 3, the sedimentation time of low-temperature refining agent BBB is 4～15s, and the sedimentation time of common refining agent FRD-88 is 10～60s.In general pre-treatment process, it is 5～20s that the sedimentation time of refining agent is required, and therefore low-temperature refining agent BBB is applicable to pre-treatment process.
2.1.3 spumescence
The scouring and bleaching foaming characteristic of agent AAA, low-temperature refining agent BBB of test for low temperature, in table 4.
The foaming characteristic of table 4 AAA, BBB
As can be seen from Table 4, AAA shakes after 20 times, drops to 20ml at 6min inner foam height by 65ml, afterwards along with the prolongation foam height of time changes little.This illustrates that its foaming characteristic is lower; After BBB concussion 20 times, drop to 20ml at 1min inner foam height by 40ml, afterwards along with the prolongation foam height of time changes little.This illustrates that its foaming characteristic is also very low, and has certain bubble ability that presses down.
2.1.4 chelating ability
AAA counterweight metallic ions Ca
2+, Fe
2+and Mg
2+have certain sequestering power, relatively the sequestering power of itself and commercially available common chelated dispersants, the results are shown in Table 5.
The sequestering power comparison of the different dispersants of table 5
| Metal ion/(mg.g-1) | Ca 2+ | Fe 2+ | Mg 2+ |
| EDTA | 214.06 | 504.78 | 176.78 |
| Chelated dispersants HD-540 | 180.54 | 276.68 | 94.56 |
| The low temperature agent AAA that scourings and bleaching | 120.33 | 249.64 | 82.34 |
As can be seen from Table 5, the low temperature agent AAA counterweight metallic ions Ca of scouringing and bleaching
2+, Fe
2+and Mg
2+there is certain sequestering power, but compared with a little less than the sequestering power of EDTA and commercially available common chelated dispersants.In view of this, adding visual water quality and the concrete condition such as grey quality in man-hour, add separately appropriate conventional chelated dispersants.
2.1.5 the stability to hydrogen peroxide
In hydrogen peroxide bleaching process, be subject to the high-alkali catalyticing decomposition action of heavy metal ion, metal fillings and high temperature and decomposition occurs for fear of hydrogen peroxide, need in liquid, add stabilizing agent scouringing and bleaching.Low temperature scouring and bleaching agent AAA to the stablizing effect of hydrogen peroxide in table 6.
The stablizing effect of table 6 AAA to hydrogen peroxide
As can be seen from Table 6, when the temperature of scouringing and bleaching is 100 DEG C, in the situation that not adding stabilizing agent, hydrogen peroxide has substantially decomposed in 30min; Add the decomposition of hydrogen peroxide after agent AAA of scouringing and bleaching of the low temperature of 3g/L to need 40min left and right, the stablizing effect of hydrogen peroxide stabilizer DA-1 is suitable with adding.So, not needing to add separately hydrogen peroxide stabilizer using low temperature to scouring and bleaching in the technique of agent AAA, this is also to use one of reason that this product cuts down finished cost.
2.2AAA low temperature Scouring and bleaching process is optimized
2.2.1AAA the impact of mass concentration on the effect of scouringing and bleaching
Change the low temperature agent AAA mass concentration of scouringing and bleaching, measure it to the scouring and bleaching impact of effect of COTTON FABRIC, the results are shown in Table 7.
