Usage and Dosage:
1. Industrially: ferrous sulphate heptahydrate is mainly used as a precursor to other iron compounds. It is a reducing agent, for the reduction of chromate in cement.
2. Nutritional Supplement: Together with other iron compounds, ferrous sulphate is used to fortify foods and treat iron-deficiency anemia. Constipation is a frequent and uncomfortable side effect associated with the administration of oral supplements. Stool softeners often are prescribed to prevent constipation.
3. Colorant: Ferrous sulphate can also be used to stain concete and some limestones and sandstones a yellowish rust color.
4. Water Treatment: Ferrous sulphate has been applied for the purification of water by flocculation and for phosphate removal in municipal and industrial sewage treatment plants to prevent eutrophication of surface water bodies.
Storage:
Storage Store in cool, dry, well ventilated area, removed from oxidising agents (eg. hypochlorites), acids, metals and foodstuffs. Ensure containers are adequately labelled, protected from physical damage and sealed when not in use. Large storage areas should have appropriate ventilation systems.

THF is an important organic synthetic raw material and a solvent with excellent performance. It is especially suitable for dissolving PVC, polyvinylidene chloride and butyl aniline. It is widely used as a solvent for surface coatings, anticorrosive coatings, printing inks, tape and film coatings, and used in combination. As a reaction solvent, the thickness and brightness of the aluminum layer can be arbitrarily controlled when used in the aluminum electroplating solution. THF itself can be polycondensed (ring-opening and repolymerization initiated by cations) into polytetramethylene ether glycol (PTMEG), also known as tetrahydrofuran homopolyether. PTMEG and toluene diisocyanate (TDI) are made into special rubbers with abrasion resistance, oil resistance, good low temperature performance and high strength; with dimethyl terephthalate and 1,4-butanediol to make block polyether polyester elastic Material.
SODIUM DIISOBUTYL DITHIOPHOSPHATE C4H9O2PSSNa CAS:53378-51-1
Sodium dibutyl dithiophosphate is a good chemical reagents which is used as collector for non-ferrous metal and precious metal; Soluble in water; mainly used as flotation reagent for copper ores and zinc ores with high selective activities.Chemical and mining industries,chemical mineral processing reagent,acid reagent.
FH products are Pure nonionic derived the endosperm of guar polysaccharide (Cyamopsos tetragonolobus). The products are unique with ultra-high viscosity with fastest hydration characteristics as shown in Figure 1 below. Also, when added with other drilling components, to seawater, a KCl solution or other aqueous system, the product suspension disperses readily without lumping, even under low-shear conditions generating most of its full viscosity within just a few minutes.
PRODUCT COMPATIBILITY:
FH series of products are compatible with most of the chemicals and auxiliaries used in drilling operations. However, the products are not compatible with Arabic and Crystal gums. Also, in presence of borates they form elastic gel.
PRODUCT APPLICATIONS:
FH series of products are natural, high viscosity, fast hydrating non-Newtonian hydrocolloids with suitable cross linking components in diesel slurries and are versatile for continuous mix applications, where extremely fast hydration and subsequent viscosity development is required. They are excellent viscosifiers, stabilizers, thickeners and suspending agent for use in oil-drilling, workover fluids and several other oilfield applications like hydraulic fracturing, oil well stimulation, mud drilling, oil well capping, flocculent and liquid shoring etc. The product is used as a surfactant; synthetic polymer and deformer ideally suited for all rheological requirements of water based and brine based drilling fluids.
