CONCLUSION:

FIRST GRADE


Application: 
Sodium nitrate is used as an ingredient in fertilizers, pyrotechnics, as a food preservative, and as a solid rocket propellant, as well as in glass and pottery enamels; the compound has been mined extensively for those purposes.Sodium nitrate is also synthesized industrially by neutralizing nitric acid with soda ash.


usage & storage: 
Sodium nitrate is the important chemical material and widely used in the industries including glass, dye, detonator, metallurgy, machi nery and enamel, etc.
1.Stored in the dry and ventilation place and prevent rain and sunlight exposure. rained, heated .
2. Avoid mixing with organic compound or sulphur or reducer during storage and transportation in case of explosion 
3.Handle with care against friction and bounce while handling and pile.
4.The fire caused bu sodium nitrate can be put out by using lots of water


Packing: 
Sodium Nitrate NaNO3 Formula - 25kgs pp/pe bag (25mt/20'fcl without pallet), or as per the buyer's requirement.



1. Sodium Nitrite 99%

Appearance: White Crystal powder

7632-000


Sodium Nitrite is mainly used as the raw material of productions of nitro compound and azo dyes, etc. Sodium Nitrite is also used as mordant and bleacher for fabric dyeing, as well as metal heat treatment agent, early-strength admixture and antifreeze of cement. 

 

Notice: 

1.Stored in the dry and ventilation place and prevent rain and sunlight exposure. rained,heated .

2. Avoid mixing with organic compound or sulphur or reducer during storage and transportation in case of explosion

3.Handle with care against friction and bounce while handling and pile.

4.The fire caused bu sodium nitrate can be put out by using lots of water
