aluminium sulphate

description

Aluminum sulfate (Al2 (SO4) 3), white orthorhombic crystalline powder, density 1.69g/mL (25 C). In the paper industry, as a precipitating agent for rosin, wax emulsion and other rubber compound, as flocculant in water treatment, it can also be used as an internal combustion agent for foam extinguisher, raw materials for alum and aluminum white, oil decoloring, deodorizing agent, raw materials of some drugs, etc.. Artificial gem and advanced ammonium alum can also be made.

Matters needing attention

Explosion hazard: This product is nonflammable and irritating.
 
Health hazards: the eye, mucous membrane has a certain stimulating effect. Take lots of aluminum sulfate have a stimulating effect on the mouth and stomach.
Toxicological data: oral LC50:6207mg/kg in mice.
 
Information Ecology: usually slightly harmful to water, do not be undiluted or a lot of contact with groundwater, waterways or sewage systems, without the permission of the government is not material discharged into the surrounding environment.
 
Skin contact: remove contaminated clothing, rinse with flowing water.
 
Eye contact: lift eyelids, rinse with flowing water or saline. Medical treatment.
 
Inhalation: from the scene to the fresh air. If breathing is difficult, give oxygen. Medical treatment.
 
Ingestion: drink plenty of warm water, emetic. Medical treatment.
 
Hazard characteristics: no special combustion explosion characteristics. The formation of toxic sulfide smoke by high temperature decomposition.
Hazardous combustion products: natural decomposition products unknown.
 
Fire fighting methods: Firefighters must wear full body fire protection clothing, fire in the upper air. Fire the vessel as far as possible from the fire to the open space.
 
Emergency treatment: isolate leakage pollution area, limit access. It is recommended that emergency personnel wear dust masks (full cover) and wear protective clothing. Use clean shovels to collect in dry, clean, covered containers and transfer to safe place. If a large amount of leakage is collected, recycled or transported to the disposal site of waste disposal.
 
Operation notes: closed operation, partial air exhaust. Operators must undergo special training and strictly abide by the operating procedures. It is suggested that the operators should wear self suction filter dust masks, wear chemical safety goggles, wear poison penetration overalls, and wear rubber gloves. Avoid dust. Avoid contact with oxidants. Light and light unloading while handling, prevent packing damage. Equipped with leakage emergency treatment equipment. Empty containers may have harmful effects.
 
Storage notes: stored in a cool, ventilated warehouse. Keep away from fire and heat. Should be stored separately with oxidants, should not be mixed storage. The storage area should be equipped with suitable materials for leakage.
 
Storage: shipment to complete the packing, loading should be safe. In the process of transportation, make sure that the container does not leak, does not collapse, does not fall, does not damage. With no oxidant edible chemical conventionalmixing luck. During transportation, should be exposed to insolation, rain, anti high temperature. Complete cleaning should be carried out after the vehicle is transported.
