Powder Form Sodium Sulphate Anhydrous 99% 7757-82-6 PH 8 For Glass

Product Specification

sodium sulphate Anhydrous (anhydrous sodium sulfate) Sodium sulfate is a salt formed by the combination of sulfate and sodium ions. The chemical formula isNa2SO4Sodium sulfate is soluble in water, and most of its solutions are neutral, soluble in glycerol but insoluble in ethanol. Inorganic compounds, high purity, fine particles of anhydrous matter is called anhydrous sodium sulphate. Anhydrous sodium sulphate, white, odorless, bitter crystal or powder, hygroscopicity. The shape is colorless, transparent, large crystal or granular small crystal. Sodium sulfate is easy to absorb water when exposed to air, generating sodium sulfate decahydrate, also known as mirabilite, which is alkaline. It is mainly used for manufacturing water glass, glass, porcelain glaze, Pulp, refrigeration blending agent, detergent, desiccant, dye diluent, analytical chemical reagent, medical supplies, feed, etc. In241℃When sodium sulfate is converted into hexagonal crystallization. Sodium sulfate is a commonly used post-treatment desiccant in Organic Synthesis Laboratories.

Physical properties: Appearance and character: monoclinic system, short columnar crystal, compact block or leather phone case-shaped aggregate, colorless and transparent, sometimes with light yellow or green, easily soluble in water.

Main purpose:

1. The chemical industry is used to manufacture sodium sulfide sodium silicate water glass and other chemical products.

2. The cooking agent used in the paper industry to produce sulfate pulp.

3.glass industry is used to replace soda ash as cosolvent.

4.textile industry is used to allocate Vinylon spinning coagulant.

5.used in non-ferrous metal metallurgy, leather and other aspects.

6.used to make sodium sulfide, Pulp, glass, water glass, porcelain glaze, also used as laxative agent and barium salt poisoning antidote, etc. It is a by-product of making hydrochloric acid with salt and sulfuric acid. It is used in chemical industry to manufacture sodium sulfide, sodium silicate, etc. The laboratory is used to wash away barium salt. Industrial use as preparationNaOHAndH2SO4The materials are also used for paper making, glass, printing and dyeing, synthetic fiber, leather making, etc. Sodium sulfate is a commonly used post-treatment desiccant in Organic Synthesis Laboratories.

7.mainly used as fill material of synthetic detergent. The cooking agent used in the paper industry to manufacture kraft pulp. Glass industry is used to replace soda ash. The chemical industry is used as a material for manufacturing sodium sulfide, sodium silicate and other chemical products. Textile industry is used to allocate Vinylon spinning coagulation bath. The pharmaceutical industry is used as a laxative. It is also used in non-ferrous metallurgy, leather and other aspects.

8.make the hydration product calcium sulphoaluminate generate faster, thus accelerating the hydration hardening speed of cement. The dosage of sodium sulfate is generally cement quality0.5%~2%, can improve the early strength of concrete50%~,28The daily intensity sometimes increases, sometimes decreases, and the increase is about10%Around, it varies with cement type, curing conditions and dosage. It is also used as fill material of synthetic detergent, as well as paper industry, glass industry, chemical industry, textile industry and pharmaceutical industry.

9.Used as analytical reagents, such as dehydrating agent and digestion during nitrogen determination, and interference inhibitor in atomic absorption spectrochemical analysis. It is also used in the pharmaceutical industr

10.used in chemical industry, paper making and glass, dye, printing and dyeing and pharmaceutical industry,It is also used in the manufacture of synthetic fiber, leather making, nonferrous metallurgy, porcelain glaze, etc.,It is also used as an additive in detergents and soaps.

11.can be used as buffer in sulfate galvanizing to stabilize plating solutionpHThe value.
