WE HAVE READY STOCKS OF Precipitated Calcium Carbonate Powder IN 50 KGS BAGS. The main use of Calcium Carbonate Precipitated is in the construction industry, either as a building material or limestone aggregate for road building or as an ingredient of cement or as the starting material for the preparation of builder's lime by burning in a kiln. However, because of weathering mainly caused by acid rain.

• Calcium carbonate (in limestone form) is no longer used for building purposes on its own, but only as a raw/primary substance for building materials. Calcium carbonate is also used in the purification of iron from iron ore in a blast furnace. The carbonate is calcined in situ to give calcium oxide, which forms a slag with various impurities present, and separates from the purified iron. In the oil industry, calcium carbonate is added to drilling fluids as a formation-bridging and filtercake-sealing agent; it is also a weighting material which increases the density of drilling fluids to control the downhole pressure. Calcium carbonate is added to swimming pools, as a pH corrector for maintaining alkalinity and offsetting the acidic properties of the disinfectant agent. also used for culturing mushrooms.

1. One of the major uses of Hexamine is in the manufacture of dinitrosopentamethylene-tetramine, a blowing agent for rubber.
2. It is used as a catalyst in the manufacture of Bakelite phenol formaldehyde molding powders.
3. It is used as a basic raw material in slurry explosives.
4. It has many other applications in the manufacture of plastics, paints, foundry resins, textiles, plywood, laminated sheets, cement, fertilizers, pesticides, solid fuel tablets etc.
5. Unstabilized Hexamine is used in adhesives, coatings and sealing compounds, in the preservation of hides, as cross-linking agent for hardening phenol-formaldehyde resins and vulcanizing rubber, as corrosion inhibitor for steel, as dye fixative, as fuel tablets for camping stoves, as stabilizer for lubricating and insulating oils, for manufacture of explosives, chemical detection of metals and as an urinary antiseptic.
6. Stabilized Hexamine is used in process industry, as per the requirements of specific customers.

Polyvinyl Alcohol is used as an emulsion polymerization aid, as protective colloid, to make polyvinyl acetate dispersions.

Uses of polyvinyl alcohol include:

• Paper adhesive with boric acid in spiral tube winding and solid board production
• Thickener, modifier, in polyvinyl acetate glues
• Textile sizing agent
• Paper coatings, release liner
• As a water-soluble film useful for packaging. An example is the envelope containing laundry detergent in "liqui-tabs".
• Feminine hygiene and adult incontinence products as a biodegradable plastic backing sheet.
• Carbon dioxide barrier in polyethylene terephthalate (PET) bottles
• As a film used in the water transfer printing process
• As a form release because materials such as epoxy do not stick to it
• Movie practical effect and children's play putty or slime when combined with borax
• Used in eye drops (such as artificial tears to treat dry eyes) and hard contact lens solution as a lubricant
• PVA fiber, as reinforcement in concrete
• Raw material to polyvinyl nitrate (PVN) an ester of nitric acid and polyvinyl alcohol.
• As a surfactant for the formation of polymer encapsulated nanobeads
• Used in protective chemical-resistant gloves
• Used as a fixative for specimen collection, especially stool samples
• When doped with iodine, PVA can be used to polarize light
• As an embolization agent in medical procedures
• Carotid phantoms for use as synthetic vessels in Doppler flow testing
• Used in 3D printing as support structure that can then be dissolved away.

• Polyvinyl alcohol dust is mildly irritating to the eyes and causes discomfort if inhaled. 
• Treat as a nuisance dust and avoid inhalation or contact with eyes. 
• There are no known detrimental effects arising from short-term polyvinyl alcohol exposure either as a solid or in solution with water.
• Can cause coughing & chest discomfort

• Ammonium chloride was used in pyrotechnics in the 18th century but was superseded by safer and less hygroscopic chemicals. Its purpose was to provide a chlorine donor to enhance the green and blue colours from copper ions in the flame. It had a secondary use to provide white smoke, but its ready double decomposition reaction with potassium chlorate producing the highly unstable ammonium chlorate made its use very suspect. 
• Metalwork edit ammonium chloride is used as a flux in preparing metals to be tin coated, galvanized or soldered. It works as a flux by cleaning the surface of workpieces by reacting with the metal oxides at the surface to form a volatile metal chloride. For that purpose, it is sold in blocks at hardware stores for use in cleaning the tip of a soldering iron, and it can also be included in solder as fluxchloroammonium phosphate. The main crops are rice and wheat in asia.

PVC ADDITIVE: Calcium stearate is a waxy material with low solubility in water, unlike traditional sodium and potassium soaps. It is also easy and cheap to produce, and exhibits low toxicity. These attributes are the basis of many of its applications. Related applications exist for the magnesium stearate.

• Calcium stearate is used as a flow agent and surface conditioner in some candies such as smarties, jawbreakers and sprees.
• It is a waterproofing agent for fabrics.
• A lubricant in pencils and crayons.
• The concrete industry uses calcium stearate for efflorescence control of cementitious products used in the production of concrete masonry units i.E. Paver and block, as well as waterproofing.
• In paper production, calcium stearate is used as a lubricant to provide good gloss, preventing dusting and fold cracking in paper and paperboard making.
• In plastics, it can act as an acid scavenger or neutralizer at concentrations up to 1000ppm, a lubricant and a release agent. It may be used in plastic colorant concentrates to improve pigment wetting. In rigid pvc, it can accelerate fusion, improve flow, and reduce die swell.
• Applications in the personal care and pharmaceutical industry include tablet mold release, anti-tack agent, and gelling agent.
• Calcium stearate is a component in some types of defoamers.

• Used Mainly In Pet Resin And Unsaturated Polyester Resin Manufacturing.
