product description

硫化钠又称臭碱、臭苏打、硫化碱。硫化钠为无机化合物,纯硫化钠为无色结晶粉末。吸潮性强,易溶于水。水溶液呈强碱性反应。触及皮肤和毛发时会造成灼伤。故硫化钠俗称硫化碱。硫化钠水溶液在空气中会缓慢地氧化成硫代硫酸钠、亚硫酸钠、硫酸钠和多硫化钠。由于硫代硫酸钠的生成速度较快,所以氧化的主要产物是硫代硫酸钠。硫化钠在空气中潮解,并碳酸化而变质,不断释出硫化氢气体。工业硫化钠因含有杂质其色泽呈粉红色、棕红色、土黄色。比重、熔点、沸点,也因杂质影响而异。

Sodium sulfide isalso called stinky soda, stinky soda, and alkali sulfide. Sodium sulfide is aninorganic compound, and pure sodium sulfide is a colorless crystalline powder.Strong moisture absorption, easily soluble in water. The aqueous solution was stronglyalkaline. Causes burns when touching skin and hair. So sodium sulfide iscommonly known as alkali sulfide. The aqueous sodium sulfide solution willslowly oxidize in the air to sodium thiosulfate, sodium sulfite, sodium sulfateand sodium polysulfide. Due to the rapid formation of sodium thiosulfate, themain product of oxidation is sodium thiosulfate. Sodium sulfide deliquesces inthe air and is carbonated to deteriorate, which continuously releases hydrogensulfide gas. Industrial sodium sulfide is pink, brownish red, and khaki due toimpurities. Specific gravity, melting point, and boiling point also varydepending on the effects of impurities.

常温下纯品为无色或微紫色的棱柱形晶体,工业品因含杂质常为粉红、棕红色、土黄色块。

具有臭味。溶解于冷水,极易溶于热水,微溶于醇。工业品一般是形不同结晶水的混和物,又含有不同程度的杂质,除外观色泽不同外,密度、熔点、沸点等亦因杂质影响而各异。

At roomtemperature, pure products are colorless or slightly purple prism-shapedcrystals, and industrial products are usually pink, brown-red, and khaki yellowbecause of impurities.

Has an odor.Dissolved in cold water, easily soluble in hot water, slightly soluble inalcohol. Industrial products are generally a mixture of different crystalwaters, and contain different levels of impurities. In addition to differentappearance and color, density, melting point, and boiling point also vary dueto the influence of impurities.

产品用途 Product Usage

1、染料工业中用于生产硫化染料,是硫化青和硫化蓝的原料。印染工业用作溶解硫化染料的助染剂。制革工业中用于水解使生皮脱毛,还用以配制多硫化钠以加速干皮浸水助软。造纸工业用作纸张的蒸煮剂。纺织工业用于人造纤维脱硝和硝化物的还原,以及棉织物染色的媒染剂。制药工业用于生产非那西丁等解热药。此外还用于制硫代硫酸钠、硫氢化钠、多硫化钠等。

2、在铝及合金碱性蚀刻溶液中添加适量的硫化钠可明显改善蚀刻表面质量,同时也可用于碱性蚀刻液中锌等碱溶性重金属杂质的去除。

3、硫化钠还可用于直接电镀中导电层的处理,通过硫化钠与钯反应生成胶体硫化钯来达到在非金属表面形成良好导电层的目的。

4、用作缓蚀剂。也是硫代硫酸钠、多硫化钠、硫化染料等的原料。

5、用于制造硫化染料,皮革脱毛剂,金属冶炼,照相,人造丝脱硝等。

1. It is used inthe dye industry to produce sulfur dyes and is the raw material for sulfur blueand sulfur blue. The printing and dyeing industry is used as a dye aid todissolve sulfur dyes. It is used in the tanning industry to hydrolyze anddepilate raw hides, and it is also used to formulate sodium polysulfide toaccelerate the soaking of dry skin to help soften. The paper industry is usedas a cooking agent for paper. The textile industry is used as a mordant for thedenitration and reduction of nitrates of man-made fibers, and for dyeing cottonfabrics. The pharmaceutical industry is used to produce antipyretics such asphenacetin. It is also used in the production of sodium thiosulfate, sodiumsulfide, sodium polysulfide and the like.

2. Adding anappropriate amount of sodium sulfide to the alkaline etching solution ofaluminum and alloy can obviously improve the quality of the etching surface,and it can also be used to remove alkali-soluble heavy metal impurities such aszinc in the alkaline etching solution.

3. Sodium sulfidecan also be used for the treatment of conductive layers in directelectroplating. The colloidal palladium sulfide is formed by the reaction ofsodium sulfide and palladium to achieve the purpose of forming a goodconductive layer on non-metallic surfaces.

4. Used ascorrosion inhibitor. It is also a raw material of sodium thiosulfate, sodiumpolysulfide, and sulfur dyes.

5. Used in themanufacture of sulfur dyes, leather depilatory agents, metal smelting, photography,rayon denitration, etc.
