Generally ranges from 2500 yuan / ton to about four or five thousand yuan a ton, the specific price according to the price of raw materials, the content of sodium hydroxide, the form of sodium hydroxide, manufacturers and other factors to decide. Caustic soda is the common name of sodium hydroxide, it is a more important and commonly used chemical raw materials.
Expanding knowledge: where to buy caustic soda and how to identify the real
Caustic soda where to buy:
Generally, if you need to purchase large quantities of caustic soda for industrial production, it is recommended that you directly contact manufacturers to place wholesale orders, and if you are a small amount of purchase.
General, if the industrial production needs to purchase large quantities of caustic soda, it is recommended to contact the manufacturer directly to order wholesale, if it is a small amount of purchase, such as for experimental use, or home with the sewer, you can buy through the following channels:
1, to the plating materials sales store can be purchased at the same time reagent grade and industrial grade sodium hydroxide.
2, to the chemical reagent store can buy reagent grade sodium hydroxide.
3.You can buy industrial grade sodium hydroxide at chemical reagent stores, and some of them will also supply reagent grade.
How to identify the authenticity of caustic soda:
1, from the appearance of judgment
Pure caustic soda generally refers to the content of more than 96% of the sodium hydroxide, so that the caustic soda is a semi-transparent crystals between white and transparent. If you feel that the caustic soda you buy is not the right color, or has black or other color impurities, then it proves that it is not high purity or is fake. Secondly, caustic soda flakes are brittle and will instantly crumble and break apart when pressed hard. Caustic soda water is smooth feeling to the touch and is completely transparent, if there are insoluble impurities, it is also impure.
2, look at the temperature when dissolved
Caustic soda dissolving process is to give off a lot of heat, you can put the caustic soda into the water, touch the outer wall of the diluted liquid container, feel the temperature, generally about 2 two caustic soda dissolved into 5 pounds of water, the temperature is about 50 ° C or more after 10 seconds. Low content of caustic soda or fake caustic soda will not heat up or heat up less. It is important to note that you should never touch caustic soda flakes or caustic soda water directly with your hands, they are extremely corrosive and can damage your skin.
3, look at the price
Caustic soda prices are generally affected by a variety of factors, there are high and low, the market demand for large prices will be higher, we have to pay attention to distinguish the price of the purchase, the cost of production plus the cost of transportation, distribution markups and other costs to buy the hands of the general to be more than two dollars a catty, if it is too cheap, then it is necessary to Consider whether the caustic soda is fake or the content does not meet the standard.
