eight.Production techniqueThe manufacturing route of EPT Metabisulfite refers to two kinds of [3], dry and soaked.
(1) dry law. When the soda and drinking water are evenly stirred in accordance to a particular molar ratio, when the Na2CO3.nH2O is created to be lumpy, it is place into the reactor with a certain hole amongst the block and the block and then through into the SO2 right up until the stop of the response is concluded, the lump is removed and the concluded item is crushed.
(two) moist strategy. In EPT Bisulfite solution, a specific amount of soda is included to make the suspension of sodium sulfite, then into SO2, that is, the crystallization of sodium pyrosulfite is produced, and the completed merchandise is centrifuged and dried.

9.Storage approach:It must be saved in a awesome, dry storeroom. EPT and sealing, air oXiHu (West Lake) Dis.dation must be prevEPTd. Pay focus to humidity-proof. Rain must be lined with rain and daylight. It is strictly prohibited to retailer and combine with acids, oXiHu (West Lake) Dis.dants and dangerous toXiHu (West Lake) Dis.c substances. The item should not be stored for a EPT time. When loading and unloading, it ought to be ligEPT and ligEPT to prevent the EPT from breaking. Drinking water and various fire extinguishers can be utilized when the fireplace is misplaced.
10.Precautions for procedureShut operation to improve ventilation. Operators have to endure EPT instruction and strictly abide by the principles of procedure.
