Product Introduction
HA-LF is a low foam alkali resistant penetrant, mainly used in high concentration sodium hydroxide solution. The typical application process is mercerizing and alkali desizing.
Technical indicators
Ingredients: mixture of cresol anionic surfactants
Appearance: Yellow transparent liquid
Ionicity: Anionic
Specific gravity: 1.05
Performance and Characteristics
1. It is a highly active penetrating agent in high concentration sodium hydroxide solution.
The settling speed test of this product is as follows
Settling time of 7 seconds (the time when the cotton cloth strip disappears from the liquid surface)
MM/LF concentration 3g/L
NaOH concentration 30 ° Be ˊ Or 54 ° Tw
Temperature 20 ℃
2. The data shows that HA-LF has low foaming properties.
Time (seconds) foam height (mm)
0    10
30   4
60    0
*Condition: At 50ml30 ° Be ˊ Add 3g/L of HA-LF to the NaOH solution and pour the above solution into a 100ml cylindrical container. Shake vigorously 10 times at a temperature of 20 ℃.
3. It has good stability in NaOH solution with a concentration of 30 ° Be or 54 ° Tw.
4. In the subsequent process, it helps to remove residual alkali.
