First, product profile
Catalase: also known as hydrogen peroxide removal enzyme or
deaerator enzyme, the product can quickly and effectively decompose
residual hydrogen peroxide (change hydrogen peroxide into water and
oxygen). widely apply to textile after oxygen bleaching biological
deoxy flaws or dyeing of residual hydrogen peroxide, and shorten
process time to improve dyeing quality, reduce wastewater
discharge, also apply to hotel, hospital, laundry, hydrogen
peroxide is used to bleach or disinfecting textiles, to prevent
skin irritation, triggering inflammation and other adverse
consequences caused by presence of hydrogen peroxide residue in
fabric; also avoid fabric oxide brittle loss, thereby prolonging
period of use. The same time, product quickly and effectively break
down food processing residual hydrogen peroxide (hydrogen
peroxide), to protect food nutrients not damage, avoid hydrogen
peroxide with food enters body, such as nausea, vomiting and other
adverse reactions. Play a good role in improving food security in
The advantages of product is easy to use, safe, excellent price,
water-saving, energy-saving, section, and environmental protection,
can reduce more than 40% cost of process.
The products have LYP-30 LYP-50, high concentration and many
specifications, implementation of production standards:

1, Due to the difference of plant bleaching process and deal with
fabric, we recommend should in process run under normal temperature
(close steam), appropriate dosage is 0.1g/l, processing time is
2, If deal with extra-thick fabrics and cheese should appropriate
to increase dosage and extend action time.

Electricity (to before dyeing)
1, Calculate with 1000 kg cloth, soluble ratio 1:10.
2, Price: water (including volume of sewage) -2 yuan/ton, electric
0.58 yuan/kWh, steam -60 yuan/cubic.
Five, Product packaging and storage conditions
Pack in 25kg blue plastic barrels, or packaging according to
customer requirements. Protect from light, store at room
Six, four methods for treatment with oxygen catalase
1, Hydrogen peroxide after bleaching enzyme, adds directly to
2, After neutralization bleaching bath, plus catalase.
3, Let go bleaching effluent, re-flooding water then plus catalase.
4, Drain bleaching effluent, fabric wash once with water, plus
water and catalase.
Seven, detection method of catalase
In 25 ℃, PH = 7, decomposition 1μmol hydrogen peroxide per minute
amount is enzyme 1U.
