How should Caustic Soda be stored and transported?   Sodium hydroxide (NaOH), commonly known as caustic soda, is a strong alkali with strong corrosivity. It is generally in the form of flakes or pearls, and is easily soluble in water (exothermic when dissolved in water) and forms an alkaline solution. Caustic Soda generally adopts 25kg three-layer plastic woven bags, the inner and outer layers are plastic woven bags, and the middle layer is plastic inner membrane bags. Caustic Soda is classified as category 8.2 alkaline corrosive goods in the classification and marking of commonly used hazardous chemicals (GB 13690-92), which belongs to class 8 dangerous goods, and the hazard code is 1823. It should be stored in a ventilated and dry warehouse or shed. The packaging container should be complete and sealed. It shall not be stored and transported together with inflammables and acids. Pay attention to damp proof and rain proof during transportation. In case of fire, water, sand and various fire extinguishers can be used to put out the fire, but firefighters should pay attention to the corrosivity of caustic soda dissolved in water. Caustic Soda is widely used. It is used in light textile industry such as papermaking, synthetic washing and soap, viscose fiber, rayon and cotton fabrics, pesticide, dye, rubber and chemical industry, oil drilling, petroleum industry for refining petroleum grease and tar, as well as national defense industry, machinery industry, wood processing, metallurgy industry, pharmaceutical industry and urban construction. It is also used in the manufacture of chemicals, paper, soap and detergent, rayon and cellophane, the processing of alumina from bauxite, and the mercerization of textiles, water treatment, etc.

What are the precautions in the use of caustic soda Caustic soda is generally flaky or granular. It is easy to dissolve in water to form alkaline solution, and it is also easy to deliquesce. It is easy to absorb water vapor and carbon dioxide in the air. Hydrochloric acid can be added for testing. It is used in the production of paper, soap, dyes, rayon, metal smelting, oil refining, cotton finishing, coal tar product purification, food processing, wood processing and machinery industry. Add water to dilute or dissolve Caustic Soda, prepare 1~2 Caustic Soda solution for spray disinfection, which is mainly used for the disinfection of livestock houses and vehicles, and 50 solution is used for the corrosion of newborn horns of cattle and sheep. Note: the bactericidal power of Caustic Soda solution tends to increase with the increase of concentration and temperature, so the disinfection effect of hot solution is good; Adding a small amount of sodium chloride to the Caustic Soda solution can improve the sterilization effect; As the Caustic Soda solution is a strong alkali, attention should be paid to the protection of disinfection personnel during disinfection to avoid burning people and animals, which is corrosive to textiles and metalware, and is not suitable for disinfection of these items. Livestock and poultry houses and utensils shall be disinfected with Caustic Soda solution for half a day, and then washed with clean water to avoid burning livestock and poultry hoofs or skins. Caustic soda has strong hygroscopicity. If it is used for high-temperature calcination, it should be mixed evenly as far as possible, calcined in a short time, and should not be placed for a long time. When preparing the solution, it must be fully stirred. On the one hand, Caustic Soda releases a lot of heat in the dissolution process, melting and hardening at the bottom of the container. In addition, Caustic Soda is highly corrosive and has a strong pungent smell when dissolved in water. When used in large quantities, ventilate and wear gas masks.

Flake Caustic Soda and granular Caustic Soda are common and used solid alkali, and granular Caustic Soda is easier to use than flake one, but the manufacturing process of granular is more difficult and messy. Therefore, the price of granulated Caustic Soda is naturally higher than that of flake Caustic Soda. In addition to being used in the industrial field and construction industry, flake Caustic Soda can also be used as a cleaning agent to clean oil dirt, and its effect is obvious. A range hood needs 100 grams of flake Caustic Soda. Use a plastic basin that can hold the downwind wheel, fill half of the basin with more hot water, and put flake Caustic Soda into the liquid medicine. Then remove the wind wheel, put it into the potion and soak it for five or six minutes, and then turn it over and soak it continuously. Through soaking, the grease almost all falls off, and then washed with clean water, that is, dry and clean. After the wind wheel is washed, the used Caustic Soda water can wash the drum bellows: wear rubber gloves, use steel balls, scrub the drum bellows, rub it almost, and then wipe it clean with a dry rag. The filter screen should also be soaked in the potion for a while, and then brushed with a toothbrush. After that, throw the rags and steel wire balls into the potion prepared with flake Caustic Soda, and put them in clean water for a while. It looks like a new one.

The difference between flake caustic soda and granular caustic soda in application. We know that both granular caustic soda and flake caustic soda are sodium hydroxide in composition. The difference lies in their forms, so there are some differences between their applications. Granular caustic soda is mainly used as chemical raw materials, which is an important basic chemical raw material, and has a wide range of uses. The chemical industry is used to manufacture formic acid, oxalic acid, borax, phenol, sodium cyanide and soap, synthetic fatty acids, synthetic detergents, etc. Textile printing and dyeing industry is used as desizing agent of cotton cloth, solvent of scouring agent, mercerizing agent, vat dye and navy blue dye. It is used in the smelting industry to manufacture aluminum hydroxide, alumina and metal surface treatment agents. The instrument industry is used as acid neutralizer, decolorizer and deodorant. The adhesive industry is used as starch gelatinizer and neutralizer. In addition, it is widely used in enamel, medicine, cosmetics, tanning, paint, pesticides, glass and other industries. Flake caustic soda, white translucent sheet solid, is a basic chemical raw material, which is widely used in paper making, synthetic detergent and soap, viscose fiber, rayon and cotton fabrics and other light textile industries, pesticides, dyes, rubber and chemical industries, oil drilling, oil refining and tar refining, as well as machinery industry, wood processing, metallurgical industry, pharmaceutical industry and urban construction. It is also used in the manufacture of chemicals, paper, soap and detergent, rayon and cellophane, the processing of bauxite alumina, and for mercerizing textiles and water treatment.

Sodium hydroxide, also known as caustic soda, its main chemical component is sodium hydroxide, which is highly alkaline and absorbent. If directly placed in the air, it can absorb water in the air and deliquesce into liquid sodium hydroxide, namely liquid alkali. In solid state, caustic soda mainly can be divided into flake caustic soda and granular caustic soda. Brief Introduction: Product Name: Sodium Hydroxide Other Name: Caustic Soda Chemical Formula: NaOH CAS No.: 1310-73-2 Formula Weight: 40.00 Melting Point: 318 ℃ Boiling Point: 1388 ℃ Solubility(water): 111 g/100 ml(20 ℃) Density: 2.13 g/cm3 UN No.: UN 1824 8/PG 2 HS Code: 2815110000 Uses: It is used for making special soaps and pesticides, softening hard water, refining beet sugar, descaling boilers, glass lubrication, etc., and for organic synthesis and preparation of barium salt; In chemical experiments, in addition to being used as a reagent, it can also be used as an alkaline desiccant because of its strong hygroscopicity. The Department that uses caustic soda most is the manufacturing of chemicals, followed by paper making, aluminum smelting, tungsten smelting, rayon, rayon cotton and soap manufacturing. In addition, in the production of dyes, plastics, pharmaceuticals and organic intermediates, the regeneration of old rubber, the electrolysis of metal sodium and water, and the production of inorganic salts, the production of borax, chromium salt, manganate, phosphate, etc., also need to use a large amount of caustic soda.

Before use 1-MCP, to know banana better: 1.Storage and transportation characteristics (1)Species. There are great differences in storability among banana`s different species, so it is necessary to distinguish them strictly. (2)Gas, physiology. Banana has a typical respiratory peak, and there is a peak of endogenous ethylene release with respiratory jump. Ethylene has a strong ripening effect on banana. 0.2% - 0.3% ethephon at 18 ~ 20 ℃ for 70 hours, that is, the ratio of peel rhubarb or ethylene gas to banana fruit volume is 1:1000, and it can ripen and turn yellow in 2 ~ 3 days. It is known that co2>10% or 02<1% in storage will cause low 02 or high CO2 damage. In addition, co2>5% in low humidity can cause damage and odor. (3)Temperature and humidity. Bananas are sensitive to chilling injury. When the storage temperature is lower than 11 ~ 12 ℃, chilling injury occurs. The epidermis is browning and blackening, showing a "pockmarked face" shape, sunken black spots, scalding, and the flesh is astringent but not ripened and softened. When the temperature of green banana fruit is >35 ℃, although the respiration and ethylene jump of banana fruit are not affected, the de greening of banana fruit is inhibited, and bananas cannot be ripened normally, which is related to temperature <10 ℃ and humidity <80%. The humidity required for banana ripening is 85% - 90%. In winter, the humidity is low, so it is particularly important to maintain high humidity. 2.Banana harvesting Bananas must be harvested in the green and hard period before the peak of respiration. The easiest way to judge the maturity is to look at the plumpness of the fruit: when the edges and corners of the fruit are obvious, the maturity is less than 70%; When the fruit surface is nearly flat and full, the maturity is about 70%; When the fruit surface is perfect without edges, the maturity is more than 90%. Which maturity is the most suitable for harvesting is mainly determined by the length of storage time required and the distance of transportation. If it is sold locally or transported close, it can be harvested at nine maturity; Those used for storage or long-distance transportation are harvested at 70% to 80% maturity. Before use 1-MCP, to good prepare: 3.Pretreatment of bananas before storage After quality selection, the bananas are graded according to the size and maturity of the fruits. The size and maturity of the fruits used for storage and preservation should be basically the same, and then they should be trimmed, rinsed and soaked in drugs. (1).Trimming: before rinsing, carefully trim the cut of the banana handle with a half moon cutter and re cut it, so as to prevent the original cut from carrying germs and affecting the storage effect. The trimmed incision should be flat and smooth without sharp corners and fibrous whiskers, so as to prevent sharp corners from stabbing banana fruits and bacteria from invading from fibrous whiskers during storage and transportation. (2).Rinsing: after finishing, immediately put the banana into 0.1~0.2% alum water or clean water for rinsing, wash the banana, and then dry it. (3).Drug soaking: the main disease of bananas during storage and transportation is shaft rot, and the treatment of drug solution is an important measure to prevent shaft rot. Soak the rinsed and dried banana with 1000~2000 times methyl tobuzin or carbendazim solution, or imazazole 500ppm aqueous solution for 30 seconds, then take it out and put it into the bamboo basket for filtration. About 1% sucrose ester can be added to the liquid medicine, and the effect is better. The liquid medicine is filled in a large tank (pool), which is ready to use. The new liquid medicine is replaced once every 48 hours. The comb naked oats rinsed with alum water should not be soaked in the liquid medicine, and the cut of the banana handle should be dipped in the liquid medicine. 4.Preservation of 1-MCP in banana storage ⑴ Spontaneous controlled atmosphere storage at room temperature Store at normal temperature in ventilated warehouse, ordinary warehouse or underground warehouse (room). The suitable gas indexes for banana storage environment are oxygen concentration of 2%-5% and nitrogen dioxide concentration of 5%-7%. After bananas are picked and put into storage, they can be fumigated with 1-MCP in time. Under the condition of spontaneous controlled atmosphere storage at room temperature, the storage time can be extended by 2-3 times on the basis of the original fresh-keeping. The key points of management are: in the early stage of warehousing, close vents and doors and windows to insulate heat during the day, and open ventilation at night to cool down; After winter, ventilation should be carried out every 3-5 days. When the temperature outside the warehouse is lower than 12 ℃, all vents and doors and windows should be closed to keep warm. Ventilation should be carried out at noon when the temperature is high. Normal temperature storage in Guangdong is mainly used for banana storage in winter and spring (November March), but this method is not suitable in hot summer. ⑵ Low temperature storage Bananas that need long-distance transportation or long-term storage should be stored and transported at low temperature. The most suitable storage temperature for bananas is 11-13 ℃, and the relative humidity is 90% - 95%. Similarly, after bananas are picked and put into storage, they can be fumigated with 1-MCP in time. Under low-temperature storage conditions, the storage time can be extended by 2-3 times on the basis of the original fresh-keeping.

Main uses of calcium carbide 1.Making acetylene Reaction principle:CaC2+2H2O→Ca(OH)2+CH≡CH↑ CaC2 can conduct electricity. The higher the purity, the easier it is to conduct electricity. 2.Other uses (1)Acetylene produced by the reaction of calcium carbide with water can synthesize many organic compounds For example: synthetic rubber, artificial resin, acetone, ketene, carbon black, etc; At the same time, acetylene oxygen flame is widely used in metal welding and cutting. (2)When powdered calcium carbide is heated with nitrogen, it reacts to produce calcium cyanamide, that is, lime nitrogen. When heated, lime nitrogen reacts with salt to produce cyanide melt, which is used in gold mining and non-ferrous metal industry. (3)Calcium carbide itself can be used as desulfurizer in iron and steel industry. (4)Polyvinyl chloride (PVC) is produced by calcium carbide method. Acetylene (C2H2) is generated by calcium carbide (CaC2) in water. Vinyl chloride monomer (ch2chcl) is synthesized from acetylene and hydrogen chloride (HCl), and then vinyl chloride is generated into polyvinyl chloride through polymerization reaction; Chemical reaction method. 3.Health hazards Damage the skin, causing skin itching, inflammation, "bird's eye" ulcer, and melanoderma. Skin burns are characterized by long-term non healing of the wound and chronic ulcer. Exposed workers have less sweating, enamel damage, and an increased incidence rate of dental caries. Explosion hazard: This product is flammable when wet. 4.Hazardous characteristics It does not burn when dry, and can quickly produce highly flammable acetylene gas in case of water or moisture. When it reaches a certain concentration in the air, explosive disasters can occur. It can react violently with acids. 5.Industrial process Electric furnace smelting method and oxygen heating method are generally used in industry. Electric furnace smelting method is to melt coke and calcium oxide (molecular formula Cao) in an electric furnace at about 2200 ℃ to produce calcium carbide (molecular formula CaC2). Oxygen heating method: that is, smelting CaC2 (calcium carbide) with oxygen enriched oxygen heating method in blast furnace, extracting carbon from limestone, high temperature and low pressure gas generator. This three furnace process technology enables CaC2 production to comprehensively utilize the waste heat and coal ash in the coal gasification process. After the coal ash is added and melted, CaC2 and ferrosilicon are generated (when purifying CaC2); High temperature and low pressure; The gas producer makes the production (generation) of gas natural. For each ton of 80% CaC2 smelted, about 168kg of pure carbon is extracted from limestone to produce 6000-2600 m3 of gas (CO is 55-95%) and about 4.5 tons of methanol can be produced. Oxygen enrichment not only improves the furnace temperature, but also improves the co quality of gas. Oxygen is particularly dual-use. The gas after the utilization of coal heat energy is used in coal chemical industry or clean power generation. This process is energy free CaC2 production and gas production. 6.Operation processing Closed operation, ventilation. The operators have been specially trained and strictly abide by the operating procedures. It is recommended that operators wear self-priming filter dust masks, protective glasses, chemical protective clothing and rubber gloves. Avoid dust generation. Avoid contact with acids and alcohols. Pay particular attention to avoid contact with water. Handle with care to prevent package and container damage. Equipped with leakage emergency treatment equipment. Emptied containers may leave harmful substances.

What is Calcium Carbide Calcium carbide, inorganic compounds, white crystals, most appearance are gray black blocks, and the cross section is purple or gray. In case of water, it immediately reacts violently to generate acetylene and release heat. Calcium carbide is an important basic chemical raw material, which is mainly used to produce acetylene gas. It is also used in organic synthesis, oxyacetylene welding, etc. Brief Introduction: Product Name: Calcium carbide Other Name:acetylenogen CAS No:75-20-7 Molecular Formula:CaC2 Molecular Weight:64.10 EINECS No.:200-848-3 InChI: InChI=1/C2. Ca/c1-2;/q-2;+2 Melting Point:447℃ Density:2.22 Boiling Point:2300℃ Physical and chemical properties: the ore is yellowish brown or black massive solid, and the pure product is white crystal (purple with higher CaC2). The density is 2.22 g / cubic centimeter, the melting point is 447 ℃, the boiling point is 2300 ℃. When it meets water, it immediately reacts violently to generate acetylene and release heat. The melting point also changes with the content of calcium carbide. Impurities: calcium arsenide (CA3 as2), calcium phosphide (CA3 P2) and other impurities are often contained in calcium carbide, which will release toxic gases such as hydrogen arsenide (AsH3), phosphine (PH3) when acting with water. Therefore, acetylene produced by calcium carbide is toxic (it must be removed by concentrated H2SO4 and potassium dichromate washing solution). Relative density (water =1):2.22.
