Product Usage:
Used in the production of paper, soap, dyes, rayon, metal smelting, petroleum refining, cotton fabric finishing, coal tar product purification, and food processing, wood processing and machinery industries. Chemical experiment: can be used as a chemical experiment. In addition to being used as a reagent, it can also be used as an alkaline desiccant due to its strong water absorption and deliquescent properties. It can also absorb acid gas (for example, in the experiment of sulfur burning in oxygen, sodium hydroxide solution can be filled into a bottle to absorb toxic sulfur dioxide); sodium hydroxide is widely used in the national economy, and many industrial sectors require hydrogen sodium. The sector where sodium hydroxide is used most is the manufacture of chemicals, followed by papermaking, aluminum smelting, tungsten smelting, rayon, artificial cotton and soap manufacturing. In addition, in the production of dyes, plastics, pharmaceuticals, and organic intermediates, the regeneration of old rubber, the electrolysis of sodium metal, water, and the production of inorganic salts, the production of borax, chromium salts, manganese salts, phosphates, etc., must also be used When a lot of caustic soda. At the same time, sodium hydroxide is one of the important raw materials for the production of polycarbonate, super absorbent polymer, zeolite, epoxy resin, sodium phosphate, sodium sulfite and a large amount of sodium salt.

Warehousing and transportation:
The solid sodium hydroxide is put into a 0.5 mm thick steel drum and sealed tightly, and the net weight of each drum does not exceed 100 kg; plastic bag or two-layer kraft paper bag with full or middle opening steel drum; screw-top glass bottle, iron lid pressure glass Ordinary wooden boxes outside bottles, plastic bottles or metal drums (cans); glass bottles, plastic bottles or tin-plated steel drums (cans) with threaded mouths, full-bottom grid boxes, fiberboard boxes or plywood boxes; tin-plated steel drums ( Cans), metal drums (cans), plastic bottles or metal hose outer corrugated boxes. The packaging container should be complete and sealed, with obvious signs of "corrosives". Sodium hydroxide is slightly corrosive to glass products, and both will generate sodium silicate, which makes the piston in the glass instrument stick to the instrument. Therefore, do not use glass bottle stoppers when holding sodium hydroxide solution, otherwise the bottle cap may not be opened. For railway transportation, steel drums packed in gondola cars can be used for transportation. The packaging should be complete when shipping, and the loading should be secure. During transportation, ensure that the container does not leak, collapse, fall, or damage, and is moisture-proof and rain-proof. If the packaging container is found to be rusted, cracked, holes, melted water, etc., the packaging should be replaced immediately or shipped early. The damaged container can be repaired by soldering. Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature does not exceed 30℃, and the relative humidity does not exceed 80%. Mixed shipment and transportation with combustibles or combustibles, acids, edible chemicals, etc. is strictly prohibited. Transportation vehicles should be equipped with leakage emergency treatment equipment during transportation.

Safety Precautions:
Closed operation, strengthen ventilation. Operators must undergo special training and strictly abide by operating procedures. It is recommended that operators wear self-priming filter dust masks, chemical safety glasses, anti-poison penetration overalls, and rubber gloves. Avoid generating dust. When handling, load and unload with care to prevent damage to packaging and containers. Equipped with leakage emergency treatment equipment. The operator wears labor protection equipment during use or transportation.
