Manual Relative Density Testing Apparatus

The primary use of Ammonium Sulphate is as a fertilizer for alkaline soils. In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth. The main disadvantage to the use of Ammonium Sulphate is its low nitrogen content relative to Ammonium Nitrate, which elevates transportation costs. It is also used as an agricultural spray adjuvant for water soluble insecticides, herbicides, and fungicides. There it functions to bind iron and calcium cations that are present in both well water and plant cells. It is particularly effective as an adjuvant for 2,4-D (amine), glyphosate and glufosinate herbicides.

We are supplier and exporter of Hematite Powder. Hematite Powder is a mineral, coloured black to steel. It is mined as a main of iron ore and used as a weighting agent in oil drilling. It is the mineral form of iron(III) oxide (Fe2O3). Fluids weighted with API Hematite Powder contain fewer solids by volume than, making higher mud fluids possible. API Grade Hematite Powder is applicable in all types of drilling fluids, including freshwater, seawater and oil-base muds. It is used as a density increasing product, used as a weighting agent and in the paint industry. Hematite is also a harder mineral than Barite so it is more resistant to particle size degradation. High Density Hematite Powder API Grade -SG = 5.19 - 5.47 -Fe2O3 = 96.70% -Fe = 71.82% -SiO2 = 0.89% -Mesh Size (passing at 98%) = 325

Metal tin is mainly used in the manufacture of alloys. Tin and sulfur compounds - tin sulfide, which is similar in color to gold, is commonly used as a gold pigment. Tin's modern application is as a solder for the electronics industry. Used in various purities and alloys (often with lead or indium), tin solders have a low melting point, which makes them suitable for bonding materials.
