Industrial grade Magnesium sulfate heptahydrate
Main ingredients: Magnesium sulfate
Molecular formula: MgSO4 (or MgSO4.7H2O)
Technical indexes:
No. Item Index 1 Appearance small colorless granular crystal 2 Magnesium sulfate, % ≥ 99.50 3 Chloride (as Cl), % ≤ 0.015 4 Heavy metal (Pb), % ≤ 0.002 5 Arsenic (As), % ≤ 0.0005 6 Iron salts (Fe), % ≤ 0.002 7 Loss on ignition % 48.0-52.0 8 pH(Ph) 5-8 9 Clarity Clarify Performance and characteristics:
Appearance and property: orthorhombic, granular or quadrangular diamond crystal, colorless, transparent, aggregates of white, pink or green glass shiny shape of fibers, needles, granules or powder, odorless, bitter taste...
Solubility: soluble in water, slightly soluble in ethanol and glycerol.Uses and usage advice:
Food: Of the provisions for food supplements can be used for dairy products, the use of an amount of 3-7g / kg; use in liquid and drink milk drink an amount of 1.4-2.8g / kg; maximum use of the mineral beverages 0.05 g / kg.
Industry: Multi together with calcium for yeast with water, according to 4.4g / 100L of water were added to increase the hardness 1 degree, the use of the bitterness and produce hydrogen sulfide odor is used as tanning, explosives, paper, ceramics, fertilizers, as well. Oral laxatives and other medical, mineral water additives.
Agriculture: magnesium sulfate is used in agriculture a fertilizer, because magnesium is one of the Main ingredients of chlorophyll is commonly used magnesium deficiency potted plants or crops, such as tomatoes, potatoes, roses and other magnesium sulfate compared to other fertilizers. The advantage is that the higher solubility. magnesium sulfate is also used as bath salts.
Transportation Note: When you want to complete shipment Packing, loading should be safe during transport to ensure that the container does not leak, did not fall, do not fall, no damage is strictly prohibited and acids, food chemicals mixed mixed operation transit should prevent... exposure, rain, high temperature. Vehicle transport is completed should be thoroughly cleaned.
Handling Precautions: closed operation, enhance ventilation operator must go through specialized training, strict adherence to rules proposed operating personnel wearing self-absorption filter respirators, wearing chemical protective safety glasses, wear protective overalls on infiltration, wear rubber gloves. Avoid generating dust. Avoid contact with acids. When moving gently, to prevent damage Packing. equipped with spill response equipment. Empty containers may be harmful residues when airborne dust concentrations exceeding have to wear self-absorption filter masks when Emergency rescue or evacuation, should wear protective masks.Storage Packing:
Industrial grade Magnesium sulfate heptahydrate: PE bag lined plastic woven bag, Net wt 25kg.
Stored in a cool & ventilated warehouse. Away from fire, heat source should be stored separately from acids, etc., and avoid mixing reservoir. The storage area should be equipped with suitable material for leakage.
Polyaluminium Chloride
Main ingredients: Polyaluminium Chloride
Molecular formula: Al2Cln(OH)6-n

Standard GB/15892-2009 GB/T22627-2008 Index Drinking water grade Water treatment grade liquid solid liquid solid Al2O3 (%) ≥ 10.0 29 6.0 28.0 Basicity B (%) 40.0-90.0 30-95 Water insolubles % ≤ 0.2 0.6 0.5 1.5 PH value 3.5-5.0 3.5-5.0 Fe % ≤ --- 2.0 5.0 Arsenic (As).ppm ≤ 0.0002 0.0005 0.0015 Cd .ppm ≤ 0.0002 --- --- Cr .ppm ≤ 0.0005 --- --- Pb % ≤ 0.001 0.002 0.006 Hg % ≤ 0.00001 --- --- Performance and characteristics:
1. This product is a conventional inorganic polymer flocculant, with excellent performance and better bridging adsorption increased coagulation effect, so the adsorption capacity and cohesion are high;
2, wide PH adapt Range of water, compared with other conventional inorganic flocculants, coagulation speed of the river water, lake water, industrial wastewater, and other water quality adaptability;
3, good solubility, low corrosion, no sediment, conducive to the operation;
Uses and usage advice:
Mainly used in drinking water treatment, industrial water treatment, sewage treatment, industrial wastewater treatment.
Use should be based on water quality small test, elected purification effect, put a small amount of the best point solution should be with the distribution with the use of non-potable water should be selected according to the amount of the actual situation.
When using solid first dissolved in water to accompany dubbed 10-25% solution, then diluted with water to the desired concentration, at the time of dissolution before adding water slowly feeding, and continue stirring.
Water treatment chemicals from different manufacturers or different brands can not be mixed, and may not be mixed with other chemicals exist.
TECH and diluent slightly corrosive, but lower than other types of inorganic flocculants.
Storage Packing:
Packing is food grade polyethylene bags lined double-layer woven bag, Specification is 25Kg.
This product is prohibited be mixed with toxic substances during transportation and Storage, the product should be stored in a dry, ventilated and cool place, avoid moisture.
Handle with care, storage period of solid product is one year.
