Catalase Boli CA is applied to eliminate hydrogen peroxide residues originating from the bleaching process of textile fabrics and improve dyeing quality with reduced processing time and less effluents. It is also used to prevent skin irritation that might be caused due to the presence of hydrogen peroxide residues in textile fabrics after bleaching and/or sterilizing at hotels, hospitals and laundries.
Product CharacteristicsÂ
| Declared Enzyme: | Catalase |
| EC Number: |
EC 1.*1.1.6 |
| Activity: | *0,**0 U/ml (minimum) |
| Appearance: |
Light to dark brown liquid |
| Product pH: |
5.5 to 7.0 |
| Specific Gravity: |
1.*0 to 1.*0 |
Benefits
Save water:
Application of catalase Boli CA to the elimination of hydrogen peroxide only requires cold bath for once. Inactivation and washing is not needed before dyeing. The elimination of hydrogen peroxide can be conducted in the same bath of dyeing without washing, resulting in considerable savings of rinsing water (saved by more than *5% in average).
Save time:
Boli CA's characteristic of decomposing hydrogen peroxide in a highly efficient way results in big saving of washing time, which is roughly half of the preparation time before dyeing process.
Save energy:
Elimination of hydrogen peroxide with Boli CA does not need heating and the process flow is comparatively short, thus allowing less electricity consumption.
Safe dyeing:
Boli CA does not have any side effects on dyeing performance of vat dyes. Hydrogen peroxide is decomposed into water and oxygen, which do not have any side effects on dyes either.
Save cost:
Hydrogen peroxide is decomposed into water and oxygen without hazardous effluents, allowing considerable savings of wastewater treatment costs.
Effect of PH and Temperature
Boli CA is active at a wide pH range of 6～*0 at temperature of
*0～*0ºC (*6～**0ºF). The optimal pH is 7.0 at the optimal
temperature of *0ºC (**4ºF).
Effect of Substrate Concentration
The reaction speed of Boli CA has a positive correlation with the
concentration of substrates when the concentration of hydrogen
peroxide is less than ***0 ppm. However, the reaction speed
decreases when the concentration of hydrogen peroxide is excessive
high.
Usage
Guidelines
Take batch-wise processing for instance:
Step 1: Discharge bleaching solutions completely;
Step 2: Wash with cold water for once, or add water directly to the
required bath of dyeing;
Step 3: Adjust pH to 6～*0 (recommended to use glacial acetic acid
) and control temperature below *5ºC (**1ºF);
Step 4: Add Boli CA according to the ration of 0.1～0.2 ml per
liter of water (in case, limited processing time is allowed due to
consecutive operation, this enzyme can be applied with larger
amount without any side effects);
Step 5: Keep the reaction for *0～*0 minutes, then examine (with
Merck reagent or any other common peroxide reagent) whether the
hydrogen peroxide is eliminated completely or not. If not, keep the
reaction for another 5～*0 minutes and the decomposition shall
complete thoroughly;
Step 6: Continue to dyeing with the same bath, or wash the bleached
or sterilized fabrics with water and take it out.
Note:
The exact dosage and processing method should be adjusted to fit
for the actual situation.
