What is delay coking? Delay coking is a process used in petroleum refineries to upgrade heavy residual oils into lighter products such as gasoline and diesel fuel. It involves heating the residual oil to very high temperatures in a coker unit, which causes the oil to break down into smaller molecules that can be more easily processed into lighter products. The process is called “delay” because the...
What is adhesive? Adhesives are substances that are used to bond two surfaces together. They can be either natural or synthetic and are often used in construction, manufacturing, and other industries. Adhesives can be applied as liquids, solids, or aerosols and come in a variety of forms such as tapes, glues, sealants, and coatings. Harm of foam for adhesive? The use of foam for adhesive can cause...
WHAT IS FIBER CHEMENT？ Fiber cement is a composite material made of sand, cement, and cellulose fibers. It is a durable and low-maintenance building material that can be used for siding, roofing, and trim on both interior and exterior surfaces. It is also fire-resistant and insect-proof. Harm of foam for fiber cement board Bubble formation in fiber cement boards can be a serious problem as it can ...
What is Wet Process Phosphoric Acid？ Wet process phosphoric acid production is a process used to produce phosphoric acid from phosphate rock. It involves the reaction of sulfuric acid with phosphate rock, which produces phosphoric acid and calcium sulfate (gypsum). The gypsum is then separated from the phosphoric acid by filtration or centrifugation. The resulting phosphoric acid can be used in va...
Sea water desalination is the process of removing salt and other minerals from seawater to make it suitable for drinking or other uses. This process is used in many parts of the world to provide a reliable source of fresh water, especially in areas where there is limited access to freshwater sources. However, excessive foam problem affect the efficiency of sea water desalination. Harm of foam in s...
Urban wastewater treatment is the process of eliminating pollutants from surface runoff (storm-water) and household wastewater. The goal of this process is to produce Environment-friendly fluid waste and solid waste suitable for disposal or reuse. Physical, chemical and biological methods can be used in the treatment process to remove physical, chemical and biological pollutant...
Reverse osmosis water treatment is a solution that eliminate ions, molecules, and larger particles from drinking water under the action of a semi-permeable membrane. The operating principle of this solution is to force water through the membrane under pressure, allowing only clean and pure water to pass while blocking the passage of pollutants. Reverse osmosis is comm...
Fertilizer is a basic substance to feed every growing crops, usually organic or inorganic.It can provide essential nutrients such as nitrogen, phosphorus, and potassium to plants after adding to the soil. Fertilizers can be used to improve the quality of soil and make crops thrive. Harms of foam for fertilizer/phosphoric acid Foam in fertilizers may lead to harmful effects on crops if not applied ...
