Industrial zinc sulfide

蒙自Industrial zinc sulfide

The molecular formula is ZnS, molecular weight is 97.45, melting point is 1020 ℃(15MPa), white to gray or light yellow powder, density is 4.08g/cm3. Almost insoluble in water, but soluble in acid. Long-term placement in humid air will convert to zinc sulfate. Main uses: can be made into blue light-emitting tubes; powdered zinc sulfide is the most important electroluminescent material, light fluorescent material, used in the preparation of picture tube screen, scoreboard display, light-emitting paint, etc.; widely used in the production of infrared windows, fairing and infrared optical components; zinc sulfide is also used in leather, enamel, rubber, dyes and other industries; used as analytical reagents, phosphors, optical conductor materials. It is also used in the manufacture of dyes, coatings, pigments, glass, cured oil, etc. Used as various filters and laser window coating; Optical coating target material; X-ray fluorescent screen; Add trace radium or new thorium salt for the luminous dial of the table; Used for TV fluorescent screen, etc. The company's annual output is 8000 tons.    

Precipitated barium sulfate

The relative density is 4.50(15 ℃), the melting point is 1580 ℃, has a high refractive index (1.63~1.65), is almost insoluble in water, ethanol and acid, soluble in hot sulfuric acid. It is easy to make mixed crystal with potassium permanganate, calcium carbonate or metal nitrate. It can be reduced to barium sulfide with carbon at high temperature. It is an important basic chemical raw materials, the main purpose: used as paint, ink, plastics, advertising pigments, cosmetics, battery raw materials or fillers, rubber products both as fillers, and play a reinforcing role, polyethylene chloride resin as filler and weighting agent, printing paper and copper board paper surface coating agent, sizing agent for textile industry. Glass products are used as a fining agent, which can defoaming and increase gloss. It can be used as a protective wall material for radiation protection. Also used in ceramics, enamel, spices and pigments and other industries.

High purity barium sulfate

蒙自High purity barium sulfate

Tasteless, non-toxic. Decomposition above 1600 ℃. Soluble in hot concentrated sulfuric acid, insoluble in water, organic and inorganic acid, caustic solution, soluble in hot sulfurous acid and hot concentrated sulfuric acid. It is chemically stable and cothermally reduced to barium sulfide with carbon. It does not change color when exposed to hydrogen sulfide or toxic gases in the air. Main uses: one of the basic raw materials of the chemical industry, mainly used in the manufacture of inorganic chemical fertilizers, non-ferrous metal smelting, steel pickling, petroleum refining and petrochemical, textile printing and dyeing, national defense, pesticides, pharmaceutical tanning and coking and other industrial sectors. The company's annual output is 48000 tons.

Low iron sodium sulfide

蒙自Low iron sodium sulfide

Also known as alkali sulfide, smelly alkali, is an inorganic salt, strong moisture absorption, soluble in water, hydrolysis of sodium hydroxide and sodium hydrosulfide, aqueous solution is strong alkaline, strong corrosive. Main Uses: Used in the dye industry to produce sulfur dyes, sulfide green, sulfide blue or dye intermediate reducing agents and mordants; Used as a flotation agent for ores in the color control industry; Used as a depilatory agent for raw hides in the leather industry, and also used to prepare sodium polysulfide to accelerate the soaking and softening of dry hides; Used as a cooking agent for paper in the paper industry; The textile industry is used for denitrification of man-made fibers and reduction of nitrided and mide, as mide; the pharmaceutical industry is used to produce phenacetin and other antipyretic drugs; in addition, it is also used to make sodium thiosulfate, sodium hydrosulfide, sodium polysulfide, etc.; it is widely used in textile, pigment, rubber, pharmaceutical and other production industries, and is one of the important inorganic salt industrial products. The company's annual output is 60000 tons.
