Storage and transportation of products by sodium nitrite manufacturers

Many people do not know much about sodium nitrite, so what does it belong to? Today, sodium nitrite manufacturer Shandong Hailan Chemical Industry Co., Ltd. popularizes science for everyone.

Sodium nitrite (NaNO2) is an inorganic salt ionized and formed by nitrite ion and sodium. Sodium nitrite is easy to deliquesce and soluble in water and liquid ammonia. Its aqueous solution is alkaline and its pH is about 9. It is slightly soluble in organic solvents such as ethanol, methanol and ether. Sodium nitrite has a salty taste and is used to make fake table salt. Sodium nitrite will react with oxygen to form sodium nitrate when exposed to air. If heated to above 320 ℃, it will decompose to produce oxygen, nitrogen oxide and sodium oxide. Contact with organic matter is easy to burn and explode. Because of its salty taste and cheap price, it is often used as an unreasonable substitute for table salt when making illegal food. Because sodium nitrite is toxic, food containing industrial salt is very harmful to humans and carcinogenic.Storage and transportation of products by sodium nitrite manufacturers

Sodium nitrite should be placed in a cool, dry and ventilated warehouse. Doors and windows are tight to prevent direct sunlight. It can be stored in the same stock as other nitrates other than ammonium nitrate, but stored separately from organic matter, flammable substances, reducing agents, and fire sources.

Packing method: two-layer plastic bag or one-layer plastic bag outside sack, plastic woven bag, latex cloth bag; plastic bag outside composite woven bag (polypropylene three-in-one bag, polyethylene three-in-one bag, polypropylene two-in-one bag , Polyethylene two-in-one bag); screw-open glass bottles, iron-capped glass bottles, plastic bottles or metal barrels (cans) outside ordinary wooden boxes; screw-open glass bottles, plastic bottles or tin-plated thin steel barrels (cans) Grate box, fiberboard box or plywood box with full bottom.

Warehousing and acceptance: mainly check the packaging for leaks, tight and effective sealing, rain, moisture, etc.

Stacking toma mat: the stack should be 15-30cm high. The height of the stack should not exceed 2.5m, to keep the stack secure and safe, with a stack distance of 80-90cm and a wall distance of 30-50cm.

In-store inspection: In addition to daily safety inspections of warehouses and stacks before and after shifts, the custodians should also conduct quality inspections of the items under management every 3 months and make records.

Temperature and humidity management: strictly control the temperature in the hot season, the warehouse can adopt the method of sealing the warehouse, try to keep the warehouse dry, and allow natural ventilation in the dry season. The temperature in the warehouse is below 30 ℃, and the relative humidity is below 75%.

Safe operation: Operators must wear work clothes and gloves; during operation, they must be handled with care, and rubbing, throwing, bumping, rolling are strictly prohibited; all acceptance inspection operations should not be carried out in the warehouse, and should be carried out at the designated place.

Storage period: two years.
