When preparing, transferring and storing polyacrylamide solution, iron ions should be avoided as far as possible. The iron ions can make the polyacrylamide degrade. #Superkim #flocculant

Fly ash - Class F Class "F": The burning of harder, older anthracite and bituminous coal typically produces Class F fly ash. This fly ash is pozzolanic in nature, and contains less than 7% lime. Possessing pozzolanic properties, the glassy silica and alumina of Class F fly ash requires a cementing agent, such as Portland cement, quicklime, or hydrated lime—mixed with water to react and produce cementitious compounds. Alternatively, adding a chemical activator such as sodium silicate to a Class F ash can form a geopolymer. #concrete #construction #readymixconcrete #durability

The increasing use of alternative fuels in #cement production has led to increased wear on kiln refractories. Infiltration of sulphur oxides, alkali sulphates, and chlorides require more frequent attention to the state of the refractory to ensure continued safe operation of the kiln line. 💡 Larry Morley, Applications Manager for HarbisonWalker International, highlighted this topic recently in the #May issue of the International Cement Review. ⬇ Click below for the full article, where Larry discusses first understanding the wear, planning ahead, and using research-based support to cement operators across the globe. 🔗 https://lnkd.in/eucQfKQB #thinkHWI #wearecalderys #innovation #refractories

HK-SSL Sodium silicate liquid create intricate gel-like structures that interact with the clay and non-clay surfaces of the formation, forming a protective barrier against water absorption and effectively stabilizing the shale structure. Sodium Silicate Liquid Drilling additive is a water-soluble sodium silicate that is used in the oilfield industry for wellbore stabilization. #SodiumSilicate #Fluids #WaterAbsorption #ShaleStructure #LiquidDrillingAdditive #WaterSoluble #OilfieldIndustry #WellboreStabilization #hkdrilling

Changing fuels = changing refractory wear! Interesting read from Larry Morley.

Water retention by drilling fluids (Muds) Mud contains ~80% water. It will collapse the rocks if, filtered out. Then, how the water is retained in mud?   ‘Hydrogen bonds’ bind the water molecules to mud additives. Carboxy Methyl Cellulose (CMC) and Poly Anionic Cellulose (PAC) are normal constituents of mud, under different brand names. PAC is heavily substituted CMC. They make hydrogen bonds with water and restrict it from filtering out to rocks. You know, we measure this property inversely by ‘water loss’ or ‘filtration loss control’ values. #drillingfluids

Demineralised Plant Demineralized Water also known as Deionized Water, Water that has had its mineral ions removed. Mineral ions such as cations of sodium, calcium, iron, copper, etc and anions such as chloride, sulphate, nitrate, etc are common ions present in Water. Deionization is a physical process which uses specially-manufactured ion exchange resins which provides ion exchange site for the replacement of the mineral salts in Water with Water forming H+ and OH- ions. #DemineralizedWater #DeionizedWater #WaterPurification #IonExchange #MineralRemoval #CleanWater #WaterTreatment #PureWater #H2O #WaterQuality #EnvironmentalEngineering #IndustrialWaterTreatment #IonExchangeResin #WaterDeionization #ChemicalFreeWater

📌The steel industry cannot be conceived without the use of lime, ever-present during the whole steel-making process. 📌The addition of lime is necessary in electric arc furnaces, AOD converters, in refining ladles… 📌Lime in steel-making can be a purifier to eliminate impurities, to remove Sulphur, removing phosphorus, it can act as a flux, neutralizing. And all with a specific goal, that of transforming iron ore into steel and other ferrous products. ✨Globe Stone Hills is ever ready to supply you with calcium carbonate, calcium oxide, calcium hydroxide, in any quantity, we can also export to all countries. 🌏 Please contact us through: 📞 201024869002+ 📞 201122002931+ 📱201555500451+ ‏‏📧/gstonehills@gmail.com ‏📧/sales@globestonehills.com ‏📧/info@globestonehills.com https://lnkd.in/d_hHXPiY #calciumcarbonate #Calciumoxide #Calciumhydroxide #iron #export
