Harm of foam: Foam in cement mortar can reduce the strength of the mortar, reduce its water-resistance, and increase its permeability. This can lead to structural damage over time due to water infiltration, which can cause cracking and spalling of the mortar. Foam also reduces the bond between the cement and aggregate, resulting in a weaker mortar. In addition, foam can trap air bubbles in the mor...
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...
Foam is often used as a delivery system for pesticides, but it can be dangerous if not used properly. Foam can trap and concentrate the pesticide in one area, leading to an increased risk of exposure to humans and animals. It can also cause damage to plants and other organisms if not applied correctly. Additionally, foam can be difficult to remove from surfaces and may leave behind residues that c...
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 ...
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...
Biological water treatment is a solution that eliminates contaminants from wastewater by means of living organisms. This type of treatment is commonly used in industrial settings that generate large volumes of wastewater, such as food processing factories. The solution works because the organisms used in the process consume the contaminants and break them down into harmless by-products. In contras...
