Application of Sodium percarbonate

Sodium percarbonate is used as an active oxygen component in detergents, bleaches and cleaning agents. Due to the unsatisfactory storage stability of the uncoated sodium percarbonate in warm/moist surroundings and in the presence of certain detergent and cleaning agent components, sodium percarbonate must be stabilized against the loss of active oxygen. An essential principle of stabilization involves encasing the sodium percarbonate particles in a coating of components having a stabilizing action. Here comes the definetion: the coated sodium percarbonate is the sodium percarbonate crystals coated with single or multiple layers of various substances in order to increase active oxygen stability and optimize storage and ensiling properties.
Coated sodium percarbonate is the more commonly commercialized peroxide compared with the uncoated sodium percarbonate. But the uncoated product is still the preferred ingredient for simply mixing with enough quantity of soda ash and some surfactants to form the popular oxygen bleaches.
4.Application of Sodium Percarbonate:
Sodium Percarbonate is a new type excellent detergent and bleaching agent based on hydrogen peroxide.It is a good cleaning and bleaching agent at normal temperature, gives good sense of touch and brilliance to the fabric and has strong fungicide effect. Fruits and vegetables treated with sodium percarbonate can be kept fresh,and be stored for a long time. In medicine,it can be kill staphylococcus,and colon bacillus. It has wide application in electro-plating,wood,anti-corrosion,waste water treatment,etc.This product is a white particle powder,non-toxic no contamination,non-flammablem,non-explosive,easy to get damp,and soluble in water.

Packing&Storage of Sodium percarbonate

Packing of Sodium percarbonate:
25Kg (N.W.) sodium percarbonate packed in a plastic woven bag, inside lined with plastic bag 500G or 1000G (N.W.) packed in a plastic bag.
Storage of Sodium percarbonate:
Conveying and storing sodium percarbonate,don't put it together with the other products and keep the packing material in good state.This product should be stored in a dried and well ventilated warehouse.

Fire Hazards
Oxidizer. Storage vessels involved in a fire may vent gas or rupture due to internal pressure.
Damp material may decompose exothermically and ignite combustibles. Oxygen release due
to exothermic decomposition may support combustion. May ignite other combustible
materials. Avoid contact with incompatible materials such as heavy metals, reducing agents,
acids, bases, combustibles (wood, papers, cloths etc.). Thermal decomposition releases
oxygen and heat. Pressure bursts may occur due to gas evolution. Pressurization if confined
when heated or decomposing. Containers may burst violently.
Fire-Fighting Measures
Evacuate all non-essential personnel
Wear protective clothing and self-contained breathing apparatus
Remain upwind of fire to avoid hazardous vapors and decomposition products
Use water spray to cool fire-exposed containers

6. Accidental Release Measures
Spill Clean-up Procedures
Oxidizer. Eliminate all sources of ignition. Evacuate unprotected personnel from equipment
recommendations found in Section 8. Never exceed any occupational exposure limit.
Shovel or sweep material into plastic bags or vented containers for disposal. Do not return
spilled or contaminated material to inventory.
Flush remaining area with water to remove trace residue and dispose of properly. Avoid
direct discharge to sewers and surface waters. Notify authorities if entry occurs.
Do not touch or walk through spilled material. Keep away from combustibles (wood, paper,
oils, etc.). Do not return any product to container because of the risk of contamination.
Wash affected skin with soap and mild detergent and large
amounts of water.
If the person is conscious and not convulsing, give 2-4 cupfuls of
water to dilute the chemical and seek medical attention
immediately. Do not inducing vomiting.

7. Handling and Storage
Storage
Oxidizer. Store in a cool, well ventilated area away from all source of ignition and out of
direct sunlight. Store in a dry location away from heat. Store at temperatures less than 40degree C.
Keep away from incompatible materials. Keep containers tightly closed. Do not store in
unlabeled or mislabeled containers.
Protect from moisture. Do not store near combustible materials. Keep containers well sealed,
seal only with original vent cap. Ensure pressure relief and adequate ventilation.
Store separately from organics and reducing materials. Avoid contamination which may lead
to decomposition.
Handling
Avoid contact with eyes, skin, and clothing. Use with adequate ventilation.
Do not swallow. Avoid breathing vapors, mists, or dust. Do not eat, drink, or smoke in work
area.
Prevent contact with combustible or organic materials.
Label containers and keep them tightly closed when not in use.
Wash thoroughly after handling.

8. Exposure Controls/Personal Protection
Engineering Controls
General room ventilation is required. Local exhaust ventilation, process enclosures or other
engineers controls may be needed to maintain airborne levels below recommended exposure
limits. Avoid creating dust or mist. Maintain adequate ventilation. Do not use in closed or
confined spaces. Keep levels below exposure limits. To determine exposure levels,
monitoring should be performed regularly.
Respiratory Protection
For many conditions, no respiratory protection may be needed; however, in dusty or
unknown atmospheres or when exposures exceed limit values, wear a NIOSH approved
respirator.
Eye/Face Protection
Wear chemical safety goggles and a full face shield while handling this product.
Skin Protection
Prevent contact with this product. Wear gloves and protective clothing depending on
condition of use. Protective gloves: Chemical-resistant (Recommended materials: PVC,
neoprene or rubber)
Other Protective Equipment
Eye-wash station
Safety shower
Impervious clothing
Rubber boots
General Hygiene Considerations
Wash with soap and water before meal times and at the end of each work shift. Good
manufacturing practices require gross amounts of any chemical be removed from skin as
soon as practical, especially before eating or smoking.
