INTRODUCTION:

Product name: Caustic Soda Flake/Solid/Pearl

CAS No.: 1310-73-2Molecular Weight: 40.00 Molecular Formula: NaOH

Appearance: White flakes, solid, pearl.

Sodium hydroxide is the principal strong base used in the chemical industry. In bulk it is most often handled as an aqueous solution, since solutions are cheaper and easier to handle. Sodium hydroxide, a strong base, is responsible for most of these applications. Another strong base such as potassium hydroxide is likely to yield positive results as well.

56 % of sodium hydroxide produced is used by the chemical industry, with 25 % of the same total used by the paper industry. Sodium hydroxide is also used for the manufacture of sodium salts and detergents, for pH regulation, and for organic synthesis. It is used in the Bayer process of aluminium production.[3]

Sodium hydroxide is used in many scenarios where it is desirable to increase the alkalinity of a mixture, or to neutralize acids.

For example, sodium hydroxide is used as an additive in drilling mud to increase alkalinity in bentonite mud systems, to increase the mud viscosity, and to neutralise any acid gas (such as hydrogen sulfide and carbon dioxide) which may be encountered in the geological formation as drilling progresses.

In the same industry, poor quality crude oil can be treated with sodium hydroxide to remove sulfurous impurities in a process known as caustic washing. As above, sodium hydroxide reacts with weak acids such as hydrogen sulfide and mercaptans to give the non-volatile sodium salts which can be removed. The waste which is formed is toxic and difficult to deal with, and the process is banned in many countries because of this.

TRANSPORT&STORAGE

Industrial solid caustic soda or other airtight device used drum packaging barrels of 0.5 mm above wall thickness, compression, packaging than 0.5 Pa sealing mouth must firmly. Packing should be clearly on the "corrosive materials" sign. This product belongs to level of inorganic alkaline corrosion items, customs 95001: Numbers. Should be stored in dry and ventilated warehouse or goods furnishings. To complete, sealed container. With fuel and acids were away. The transport process should notice moisture proof, rainproof. If discover rust, rupture occurred container, hole, melting drips water phenomena, should be replaced immediately packaging or early delivery use, can repair damaged container soldering. Fire, water, soil and can save, but fire extinguishers should pay attention to the water into the corrosive after caustic soda.

QUALITY CONTROL

Rigid quality control on inputs, process and outputs lead to high purity and consistent quality that permit standardization of its use in industry.
